Pay attention to the suitability of choosing ppe

Users, for a company, are a source of word of mouth and an incentive for product update iterations. Especially for high-tech industries such as VR, it is particularly necessary to interact with users to promote product innovation. Hypereal, the leader of the domestic VR industry, has recently demonstrated how to put “emphasizing user experience” to the extreme – CEO Huang Chaiming personally led the team and Shi Jiazhuang took the flight to solve problems for users. What's the story of the legendary Million Bet and CEO Bakutou?

The cause of the incident was that a Shijiazhuang user reflected in Hypereal's QQ group. He could not use Pano to run games on HypereAL clients, but he could run games on SteamVR platform smoothly. Users expressed that they are VR professional developers, have their own views on specific technical issues, and set a million bets with the CEO, if you can run HypereAL client, give 1 million, if not, then ask the CEO Heads. CEO Huang Chai Ming immediately expressed willingness to personally go to the commissioning equipment and immediately purchased the next flight to Shijiazhuang. This kind of sincerity and efficiency have surprised many users in the QQ group.

The next day, Chai Ming promised to fulfill his promise and personally led software and hardware engineers to the user's home. He answered all kinds of technical questions one by one. After several tests, the final staff found that Hypereal's Space-time Image Reconstruction function is incompatible with the user's hardware. This function is set to optimize the user experience, but it is incompatible with some settings of SteamVR. So it will not start when running Steam VR games. This function is enabled by default when running Hypereal games. Due to the compatibility with the user's hardware, some games cannot run.

After the problem was solved, the user also took a picture with Chai Ming and expressed his appreciation to the CEO for handling the problem. Chai Ming also stated that the user's computer configuration was very special. In the near future, specific documents will be given to summarize the incident. Late at night, Hypereal and his team took a rainy flight back to Shanghai to welcome a new week's work.

The CEO of Hypereal demonstrated how to make a good user experience with practical actions. The so-called millions of bets and gimmicks were finally solved. As the CEO of the company, there are a lot of matters that need to be dealt with, but Huang Chai Ming is passionate about interacting with users. Every day at 12 o'clock in the evening, I leave the company and sleep for 4-5 hours. At 2 am, I am still active in the user group to answer questions patiently. For him, it is normal. Collect personal feedback from the frontline personally, treat each consumer seriously, and provide solutions in a timely manner. Let Huang Chai Ming and Hypereal gain a lot of loyal followers.

The hard work and diligence of CEO Huang Chai Ming also won a lot of honors for himself. In April last year, Huang was selected by Forbes Asia as one of the 30 young talents under the age of 30. In July this year, it also listed Forbes China under 30 elite list. The authoritative magazine's affirmation gave this 85th CEO a new impetus.

"My goal is to make the best possible product at all غير مجاز مي باشدts." Huang Chai Ming said in an interview. Entrepreneurship is hard, but it is cool. With its enthusiasm for “beyond reality” and the spirit of such extremes, Hypereal, the new VR brand, has gone all the way from the summer of 2015 to the present. After all, what else can be done to a CEO who is willing to make a flight and who has personally commissioned a device for a user who has traveled thousands of miles away?

“The draft of the consultation has been reported to relevant leaders and will be reported to the State Council soon.” On March 3, at the “China DME Summit”, Xu Mingming, deputy director of the Office of the National Energy Leading Group and head of the drafting expert group, disclosed This news.
Prior to February 29, the New York Mercantile Exchange overnight electronic session, April light sweet crude oil futures prices reached a record high of 103.05 US dollars a barrel.
On the same day, in the “Chinese Inventory 2007” event just concluded, 1.3 million Internet users voted for the most popular international word for the “oil” word.
This is not only the memory of 2007, but also the reality of 2008. Deng Yusong, director of the Comprehensive Research Office of the Institute of Market Economy at the State Council Development Research Center, said: “The situation of frequent and volatile oil prices will not change in the short term.”
“National Standards” are Desiring Higher oil prices, on the one hand, have accelerated China’s steps to accelerate energy legislation and on the other hand have also expanded the path of alternative new energy sources. In particular, according to the energy endowments of “less oil, more coal, and lack of gas” in China, there is actually much room for green clean energy using coal as raw material.
It is predicted that by 2020 China's oil production will remain at around 200 million tons, oil consumption will reach 450 million tons to 510 million tons, and the dependence on imported oil will reach more than 55%. The pressure on energy supply is huge. China's proven recoverable reserves of coal are 1.02 trillion tons, accounting for 11% of the world's total reserves. The medium and long-term development seems to be available for a century.
“China’s steps in coal deep processing and clean utilization, including the replacement of alcohol ethers, are still not large enough,” said Xu Mingming. “The key to energy development in China in 2008 is to focus on energy conservation, new energy development, green energy, and clean energy. Use."
The dimethyl ether (DME), known as "sister fuel" for liquefied gas (LPG), has been proven to be the cleanest fuel after hydrogen for more than a decade of research. The largest potential use is as a substitute for city gas and liquefied petroleum gas, which is used as fuel for electricity generation and heating for civilian use. In a strategic sense, it can be used as a supplement to petroleum energy, replacing diesel as a fuel for clean vehicles.
In terms of غير مجاز مي باشدt, LPG price is 6500 yuan per ton, DME غير مجاز مي باشدt price is 3000-4000 yuan per ton, and the ratio of DME to LPG replacement is about 1.2-1.0:1, and the space for غير مجاز مي باشدt reduction is also large.
For this reason, as early as in 2006, the NDRC has issued a document saying: "The development of coal-based alcohol ether fuels such as dimethyl ether will help ease the oil supply shortage quickly, and is the focus of recent substitution work."
However, although 100% replacement with liquefied gas can be achieved technically, the industry's eagerly awaited introduction of the dimethyl ether national standard has been delayed. According to Chen Weiguo, secretary-general of the Professional Committee of Alcohols of the China Petrochemical Association, in view of the same name as the construction industry standard ("DME dimethyl ether for town gas" has been approved and implemented on January 1 this year), The relevant provisions of China's standard management, the existence of national standards to cover the issue of industry standards. “So the standard compiling team is drafting a report, and it is proposed that this national standard be renamed as 'Dimethyl ether mixture for town gas',” Chen said.
In this regard, the New Austrian Group, which has a complete new energy industry chain and one of the dimethyl ether standard participating companies, is confident. The president of the group, Yang Yu, told this newspaper: “We have both stable upstream coal and methanol supply, and a terminal logistics and distribution system. At present, more than 90% of our dimethyl ether products are used for blending with LPG, and the rest are used. For aerosols and cutting, but this is only the first step towards industrialization. In the future we need to find a better direction, that is, to replace diesel and liquefied gas."
The clean energy market urgently needs to be planned. Enterprises in the terminal sector may not be calm enough.
A person in charge of the LPG three-level station from Gaoyou, Jiangsu, complained to the reporter: “We are now generally using 20% ​​DME to burn liquefied gas to reduce غير مجاز مي باشدts, but whether it is allowed is still a problem, and the business sector will not. Therefore, the third-grade station is punished. In addition, there is no technical problem in transporting dimethyl ether using the LPG tanker, but the state stipulates that the dangerous goods transporter cannot replace the product arbitrarily. Then the public security and transportation departments found out how to deal with the punishment. ?"
In other words, the use radius and transport radius of dimethyl ether are severely limited. In this regard, Secretary-General Chen Weiguo of the Committee of Alcohol Ether is also quite helpless, because there is no guarantee of standards and regulations, if the punishment is "justified." As a result, new energy sources that have been strongly promoted in the theoretical community have in reality emerged "as long as the economic benefits can be sold without anyone's control."
In addition to the dilemma brought about by the absence of legal protection and standards, the market planning for alternative new energy is also a problem that needs to be solved urgently.
Take dimethyl ether as an example. Although China is the first country in the world to use DME for large-scale industrial production, it is the world leader in commercial applications. However, the contradiction between the dimethyl ether production capacity and the market capacity has not been well resolved, and it has become increasingly fierce.
According to Tian Chunrong, senior engineer of the Sinopec Information Department, at present, the liquefied gas market for civilian and automotive use in urban and rural areas can provide 2.9 million tons of DMC blending capacity; according to conservative estimates, this market capacity will increase to 3.3 million tons by 2010.
However, in recent years, China’s dimethyl ether production has grown explosively. In 2002, the production capacity and output were only 30,000 tons and 20,000 tons respectively, but it is estimated that by 2010, only new production capacity will reach 10 million tons, and the total production capacity will reach 16 million tons. How to deal with surplus production capacity? How to successfully introduce the improved and growing products into practical areas, and truly realize industrialization?
In response, Xu Mingming said to reporters very firmly: "Alternative energy is not enough? The technology speaks; no use? The market speaks." He believes that the "long march" method of long-distance transportation in China's energy industry is contrary to the law of energy. In the field of new energy, the government should establish standards as soon as possible to cultivate the market, build a mature pipeline, and make adequate preparations for large-scale use in the future.
Deng Yusong also believes that since the fuel-consuming retrofit cycle is generally 6-8 years, the policy utility will usually be conducted and reflected after 6-8 years. He said that although there are still relatively few oil and gas substitute products with economies of scale, economy, cleanliness, and safety at the same time, the development of the new main varieties is still a long way, but it has ushered in the best period of development.

Mud pumps are generally used in rural areas as river mud, excrement, river water, and slurry feed to provide water for irrigation, instead of picking shoulders for people, as well as for drainage and drought resistance, it is also possible to carry car heads, river mud, and compost production. It can also be used as a simple fire pump in rural areas. It can also be used as a fish-to-water clear pond, and oxygen in fish ponds. Can also be used in municipal, chemical, printing and dyeing, pharmaceutical, shipbuilding, foundry, food and other industries to pump thick liquids, contaminated liquids, pastes, quicksand and flowing sludge in urban rivers, etc. can be used as coal mines to exclude gravel and small gravel The fluid. If high-pressure water pumps and water guns are combined to form a hydraulic mechanized earthwork unit, they can be used for excavation and transportation of land leveling, river courses, ponds, air defense, and underground projects. Mud pump failure causes and remedies.

Slurry pump failure 1: Pump does not absorb water

Reason: perfusion enough water, air can not be discharged in the pump, the suction pipe leak, front liner and impeller large gap Solution: Continue filling water, check the pipe leaks, the front plate and the gap adjusting impeller

mud pump fault 2: slow pump Sheung Shui
Reason: a large front liner and impeller clearance, the air outlet duct is not sealed, evacuated full solution: gap adjustment, adjusting the water outlet pipe, a vacuum device mounted

mud Fault 3: Small water pressure, flow small

Causes: There is air in the pump, large gap between the impeller and the front liner, the clutch is not tightly closed, and the impeller or liner wears. Solution: Drain the air in the pump, adjust the clearance, adjust the clearance of the clutch friction plate, replace the impeller or the liner
Slurry Pump Fault 4: Water Pump Vibration

Causes: Concentricity between pump shaft and diesel engine (or motor), imbalance of impeller, bearing damage Solution: Adjust concentricity, balance test impeller, replace bearing
Slurry Pump Fault 5: Impeller Shaft Wears Fast

Reasons: High head of low-pressure pump, dislocation of packing, misalignment of pump shaft and back cover. Solution: Replace the high pressure pump above the head of mud pump, replace packing, adjust concentricity
Slurry Pump Fault 6: Pump Wears Fast

Reasons: poor construction environment (large particles), long transportation distance, long inlet pipe Solution: Replace the sand yard, add afterburner units, shorten the length of the inlet pipe, reduce the cavitation double-stage water ring vacuum pump, double-stage rotary vane vacuum pump , Stainless steel submersible sewage pump, non-clogging sewage pump, stainless steel self-priming sewage pump, vertical pipeline sewage pump.

[Netease Smart News, August 28th] This small, safe drone can be used with existing RFID devices.

Imagine a micro-drone rumbling in a warehouse that can automatically track and monitor remote inventory, allowing workers to freely manage and move materials. This is a new system developed by researchers at the Massachusetts Institute of Technology to prevent mismatches. The above empty perspectives help employees find specific products more quickly and enable a group of workers to move around quickly.

Most importantly, a report describing the system showed that small drones are safe when they fly around. They read inventory RFID tags “outside tens of meters” with a tolerance of 19 centimeters. However, this kind of micro-drone that is safe in the warehouse is not big enough to carry an RFID reader with a large enough data transmission range. Therefore, MIT researchers only let the drone and the standard reader transmit signals. Then fly back. This means that these small fleets can use existing RFID reading systems, software and tags.

"From 2003 to 2011, the U.S. military lost .8 billion in its warehouse," Fadeldib said. He is an assistant professor of career development at Sony Corporation and he developed this new system at the MIT Media Lab team. In 2016, the National Retail Federation of the United States announced the shrinkage of retail stores—an average of approximately .2 billion per year. Let drones find and locate items and equipment. This study will provide a fundamental technological advancement to solve these problems. ”

RFID is not a flashy technology that used to be used to save alcohol, track aquarium wildlife, or update patient tracking records in hospitals. It is also used in a large number of warehouses, so the MIT system, which was nicknamed "RFly" in the research team's paper, may be a new way of automatically tracking inventory. Especially when Amazon's drones begin to ship goods directly from the warehouse. (From: engadget and  庵 庵 庵 庵 藸 藸 藸: Li Mu晗)

The Biomass Energy Group of the Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences in a joint study with Tohoku University in Japan and the University of Saskatchewan in Canada found that when phenol is added, lignin can be completely dissolved in high-pressure hot water. The researchers explained that this is because high-pressure hot water can promote the hydrolysis of lignin to phenol oil, and the addition of phenol can prevent the re-polymerization of the hydrolyzed phenol oil.

In published research papers, researchers have clarified the path and mechanism of lignin degradation reactions under high pressure hot water conditions. According to this reaction path, lignin can be completely degraded into phenol oil and can be further processed into bioplastics, chemicals and biofuels.

Lignin is a polymer composed of phenols and has long been considered as the most stable and most difficult to degrade by biological and thermal conversion methods. Fiber alcohol and waste from paper mills contain a lot of lignin. This study is of great significance for the recycling of lignin.

In the increasingly developed mobile Internet today, wireless networks have become the "lifeline" in people's work and life. However, sometimes the wireless at home is also very powerless. Obviously, 100 megabit fiber broadband has been installed. Why do you watch video and brush? The webpage is still very card, it does not matter if it affects entertainment, but delaying work is a big deal. So today we will talk about why the wireless at home will slow down.

1. Power system applied to ARCM products

Code Meaning of Ground Protection System Type

The first letter indicates the power system's relationship to the ground:

T—directly grounded;

I—All live parts are insulated from ground or grounded at one point.

The second letter indicates the grounded relationship of the device's exposed accessible conductors:

T—The exposed conductor is directly connected to the ground for electrical connection. This grounding point is not directly related to the grounding point of the power system.

The N-exposed accessible conductors are electrically connected directly to the ground of the power system through the protection wires.

If there are letters afterwards, these letters represent the combination of neutral and protective lines:

S-neutral and protection lines are separate;

C-neutral and protection lines are one.

2. Transformer selection and installation

3. Temperature sensor installation

The temperature sensor is a custom-made NTC thermistor. It provides a temperature monitoring reference of 0 to 120°C for the device and can be used to monitor the temperature of the cable or distribution box for temperature protection.

Its external dimensions are as follows (in mm):

Select the part where the wire is located close to the wiring of the connector, and try to select the part with the insulating material. This will not only detect the temperature faster, but also ensure the electrical isolation. The black circle below is a more reasonable position.

Bind considerations:

• Try not to make electrical contact with the power supply system at the sensor mounting holes

• Try not to force the sensor's leads when tightening the second half so that the leads are not mechanically damaged.

4. Power on the alarm

Temperature alarm:

1) Is it normal alarm;

2) Remove the temperature sensor and see if the meter display is normal;

3) Check whether the temperature sensor is connected;

4) Check if the temperature sensor is damaged;

Leakage alarm processing method

Leakage finding method

1) Turn off the alarm function (set according to the product specification);

2) determine the size of the leakage current;

Constant reset of the instrument: When the residual current transformer signal of the instrument is removed and the leakage value of the instrument is displayed as 0, the current loop leakage current measurement value may exceed a dozen amperes. (The instrument can no longer operate normally)

The meter display value exceeds 3000mA: The current loop leakage current measurement is about 3A~10A. (The measuring range of the meter itself has been exceeded)

Other display instruments work properly.

3) determine the location of the leakage;

Use the clamp meter to measure each branch of the current circuit separately to see the location of the leakage value.

In the absence of a clamp meter, if the site allows power off. After each branch is powered off one by one, check the meter display value.
