Pay attention to the suitability of choosing ppe

As people's requirements for smart living are getting higher and higher, in the field of parking, the parking lot system needs to add more functions, integrate parking, payment, and parking resource integration, thus making the parking industry undergo a qualitative change. What is the current state of development of the parking system and what is the application of it in intelligent transportation?

In the field of parking, the parking system is one of the products most commonly touched by people. From the entry and exit of a single manually-managed vehicle to the current functions of parking, payment, and car-finding, the technology continues to innovate to meet the owner's need for parking. The most basic requirement, but its nature still belongs to a type of equipment that manages the entry and exit of vehicles in a parking lot. Until people mention the concept of parking resource integration, the parking system only has a functional breakthrough.

Although the functional changes in the current parking lot system are all based on the convenience of people parking, for the parking lot management, how to integrate all the parking resources together is an urgent need for them to solve. thing. How to make unified management of parking lots in the same area, including the use of parking spaces in each parking lot, the query of parking spaces, the payment of vehicles and other functions. The parking lot system plays the role of controlling the "entrance" during the period, in order to integrate all The parking resources, need to make a fuss on the software management platform, Doer Parking Cloud platform set the remaining parking spaces to query, cloud video, charge information cloud query, group management, cloud data and other major advantages, combined with the current WeChat payment function , Make parking management intelligent.

As we all know, the parking lot system is an extensive system project. It not only has the function of vehicle access management, but also includes many subsystems such as parking guidance, reverse car search, self-service payment and so on. In order to carry intelligent traffic, further open the market, parking lot System manufacturers need to further break through the bottleneck of serious homogeneity and weak technological innovation.

Stainless steel submersible pump submersible pump submersible pump price submersible pump manufacturers

There are several types of submersible pumps produced by Liangbang Pumps, so different submersible pumps have different methods for controlling the flow of water. The line package in the motor is oil intrusive, water intrusive, and dry. Before using, you must read the instructions. You can't make mistakes. If you do not use it for a long time, you must turn the impeller before use. Otherwise, you will not use the card for a long time. Die while burning the pump.

The suction tube and the pump must be filled with liquid before starting the pump. After the pump is turned on, the impeller rotates at a high speed, and the liquid rotates with the blades. Under the action of centrifugal force, it flies out of the impeller and shoots out. The ejected liquid gradually slows down in the diffusion chamber of the pump casing, the pressure gradually increases, and then the pump Outlet, discharge pipe outflow. At this time, the vacuum is formed in the center of the blade due to the liquid being thrown around to form a vacuum and low pressure area with no air and no liquid. The liquid in the liquid pool flows into the pump through the suction pipe under the action of atmospheric pressure at the pool surface. It is continuously pumped up from the liquid pool and continuously discharged from the discharge pipe.

For the use of high-lift submersible pumps, we mainly deal with the drainage. Then, for the control of the amount of water and water flow, I believe that many people are unaware of the solution. Next, I will explain the various adjustment methods for the flow control of submersible pumps.

1. Variable speed adjustment. Changing the speed of the submersible pump can change the performance of the pump, so that the operating point of the pump changes. This method is called variable speed mediation.

2. Diameter adjustment. After the impeller is turned, the performance of the water pump will change according to a certain law, so that the operating point of the pump will change. The method of turning the impeller to change the operating point of the pump is called adjusting the diameter.

3. Angle adjustment. Changing the installation angle of the blade can change the performance of the water pump so as to achieve the purpose of changing the operating point of the submersible pump. This way of changing the operating point is called the variable angle adjustment of the pump.

4. Throttle adjustment. For a water pump installation with a gate valve installed in a water outlet, when the gate valve is closed and the local resistance is increased in the piping, the characteristic curve of the piping becomes steep, and the operating point moves to the upper left along the QH curve of the pump. The smaller the gate valve is closed, the greater the increased resistance and the smaller the flow becomes. This method of changing the pump operating point by closing the small gate valve is referred to as throttling regulation or variable valve regulation.

When the small gate valve is closed, the local head loss of the pipeline increases, the characteristic curve of the pipeline system moves to the upper left, and the operating point of the pump also moves to the upper left. The smaller the gate valve is closed, the greater the local head loss and the smaller the flow. This shows that throttling not only increases the local head loss, but also reduces the amount of water outflow, which is very uneconomical. However, because of its simplicity, it is used in the performance tests of small-sized pump units and pumps.

The core technology of the Bitcoin system, blockchain, is a decentralized (open, flattened, equal, non-mandatory system structure of the central control) database technology that has entered the field of vision in recent years. . Energy Internet, as the “Internet+” smart energy product that integrates multiple energy sources, information physics, and multiple markets, has also received extensive attention from the academic and industrial communities. “Internet+” smart energy tries to establish “a new form of energy industry development in which the Internet and energy production, transmission, storage, consumption, and energy markets are deeply integrated” and realizes “equipment intelligence, multi-energy coordination, information symmetry, supply and demand dispersion, and systems Flat, trading open." Blockchain technology itself is innovating the traditional Internet structure and pattern, and ensuring trust as the core to promote efficient operation of transactions, authentication and other aspects. Similarly, blockchain technology will also promote the cooperation of multi-form energy sources and participating parties in the energy Internet era, promote the further integration of information and physical systems, and realize the diversification and low غير مجاز مي باشدt of transactions.

Blockchain technology

A blockchain is a data structure formed by an ordered link of blocks. A block refers to a collection of data. The related information and records are included in the blockchain and are the basic unit for forming a blockchain. The special data structure organization style of blockchain enables blockchain technology to have four main characteristics: decentralization, transparency, contract execution automation, and traceability. The characteristics of the blockchain technology and the concept of the energy internet are similar to some extent. See Table 1.

First, surface treatment

Surface treatment refers to the use of metal electrodeposition (commonly known as electroplating), coating (called spraying), chemical oxidation (coloring) or other processing methods to cover or form a protective film on the surface of a part. The film mainly plays an anti-corrosion effect, and also increases the appearance and durability of the product, which is an important factor directly measuring the quality of the product. Common methods for measuring the surface treatment include: thickness measurement of the cover layer, binding force inspection, salt spray and humidity test, appearance inspection, and the like. The coating is applied to the film adhesion, hardness, humidity test and visual inspection.

China's new standards for door locks

The new standards for door locks in China were released in June 2000 and implemented in October 2000. The State Light Industry Bureau and the National Center for Standardization of Daily Use Hardware issued separate notices to revise the original four door lock standards. And the original marble door lock (SG205-80) and the outer double door lock (GB8385-87) combined to increase the double buckle (Tiger) door lock and become the standard for exterior door locks. The current implementation of the light industry standard QB is the revised new standard. The exterior door locks and spherical door locks are divided into two categories, A-level and B-level. Basically, the distinction between high-end villas, apartments and commercial housing, and unit housing is clearly defined.

Second, how to choose when buying

When purchasing lock products, pay attention to the following

1. Should choose well-known products, stable quality and good after-sales service products.

2. First, check whether the marks and signs of the purchased product packaging are complete (including the implementation standards, grades, production company name, address, and production date of the product). Whether the packaging is firm or not, the content of the manual is consistent with the product, beware of exaggeration and inconsistent with the facts. phenomenon.

3. Observe the appearance quality of the product, including whether the lock head, lock body, lock tongue, handle and cover plate components and related accessories are complete, and whether the surface color of the plating parts and paint spray parts is bright and uniform, and whether there are signs of rust, oxidation, and damage. .

4. Check whether the product's use function is reliable and flexible. Select more than two products to check and check. In particular, when buying a two-way lock product, you must use all the keys to test the internal and external locks respectively. Also check the insurance organization of the product. It is recommended to try each lock at least three times.

5. Then check the key's dentising condition. If there are five spoons, each key should have no less than three different spoons. At the same time, the first tooth and the fifth tooth should not try to select the deepest spoon tooth, which will facilitate the insertion of the key. Pull and hard to break.

Total alkaloids were 514.6 soil 29.1 mg/kg. In terms of subacute toxicity, rabbits were treated with uncaria decoction twice a day, each time at 5g/kg (2.5 times the amount of treatment), and they were taken for 10 days without symptoms of poisoning. Rhynchophylla 50mg/kg continuous administration for 14 days, does not cause pathological changes in the rat viscera; dose doubled, although the liver has mild inflammatory changes, the drug returned to normal after discontinuation; no effect on diet, weight and appearance behavior .

toxicity:

The LD50 of intraperitoneal injection of rhynchophylline and rhynchophylla total mice were 162.3 mg/kg and 144.2 mg/kg, respectively, and the activity was reduced when intoxicated, and the whole body was weak. The daily decoction of 10 g/kg was given to rabbits twice. 10 days, Rhynchophylline was administered to the rats at 50 mg/kg for 14 days. There were no changes in symptoms of toxicity and visceral pathology. Rhizoma Alkaloids were fed to the young rats at 50 mg/kg and 100 mg/kg, respectively. The low-dose group had no significant effect on growth, development, liver and kidney function, and hemogram. However, in the high-dose group, the heart, liver, and kidney of the lethal animals showed obvious pathological changes. Therefore, attention should be paid when taking a large dose or long-term use. Liver and kidney function tests.

The median lethal dose of the uncariatine decoction on mice injected intraperitoneally was 26.1±4.3 g/kg or 29.05±0.8 g/kg. Uncaria twig decoction was 35.2 ± 5.4g/kg. The median lethal doses of total alkaloid hydrochloride of Uncaria rhynchophylla in mice by gavage and intraperitoneal injection were 514.6±29.1 mg/kg and 144.2±3.1 mg/kg, respectively. The median lethal doses of quercetin to mice injected intraperitoneally and subcutaneously were 162.3 mg/kg and 165 mg/kg, respectively.

The rabbits were fed with a decoction of uncaria Houttui 5g/kg twice daily for 10 consecutive days without obvious symptoms of poisoning. Young rats were treated with 50 mg/kg total alkaloid hydrochloride (therapeutic dose) for 1 day and dissected after 14 days. No visceral pathological changes were observed. However, when the dose is doubled, mild inflammatory changes occur in the liver and recovery can be quickly achieved after drug withdrawal. Weaning rats were treated with total alkaloid hydrochloride 50-100 mg/kg, once daily for 2 months, and then observed for 1 month after discontinuation. Small doses (50 mg/kg) were given to animals for growth, development, and liver There was no significant effect on renal function and blood count. Pathological examination showed only mild renal nutritional disorders. Large doses (100 mg/kg) can kill animals. Death of the animal heart, liver and kidney have obvious lesions.
