The above list is typical of the type of equipment we have supplied to a variety of industries for varying applications. Whether your process and application requires mixing during conveying, dewatering, batch metering interlocked to weigh system or conventional transfer conveying we have the experience and standard equipment to ensure you have a reliable trouble free installation.

QUANTUM designs and supplies a complete range of Screw Conveyors.

These types include:

•Conveying and transfer conveyors:

•Inclined Screw conveyor

•Horizontal Screw conveyors

•Storage Hopper Discharging & Live Bottom Bin Discharging systems

•Hopper Discharge

•Dosing and metering screw dischargers

•Twin Shafted Screw Conveyors

•Dewatering and compacting screw conveyors

•Batch metering screw feeders with self-emptying storage hoppers.

•Shaftless Screw Conveyors (Auger Covneyors)

Quantum have specialized screw conveying systems installed in chemical, mineral as well as the food and beverage industries. Our designs cater for stainless steel, mild steel with liners and special steel for abrasive materials, through to fully polished, sanitary clean down applications requiring full clean out and knock down construction. Materials handled can be micro powder to granular and lumps. The selection and type of conveyor recommended is critically dependent on the material to be conveyed.

Conveying and Transfer Conveyors: 

Quantum manufacture a standard range of screw conveyors incorporating intermediate center bearings or center less screw conveying for difficult sticky materials. Length of conveyors and size of conveyor depends on capacity and material characteristics.

Inclined and vertical conveying: 

Quantum have designed and installed both vertical and inclined screw conveyor systems. It is recommended to design all incline conveyors without using an intermediate bearing, if possible and to keep incline to less than 75o for optimum efficiency. Whether your application requires a tubular inclined conveyor or trough conveyor, Quantum will select the most suitable conveyor for your application that is suited to the material characteristics, environment, length conveyed and your specific needs such as clean down and residue. Efficiency of vertical conveyors can be as little as 10% and generally require specific design considerations; the nature of material and feed method. Our engineers can assist with the best and most suited conveyor for your needs.

Horizontal transfer conveyors 

A single conveyor can incorporate several hanger bearings over length in access of 100m. However length is very much dependent on the nature and characteristics of the material and the conveying capacity. Some materials cannot be successfully conveyed using any hanger bearings, whilst other materials will accommodate several hanger bearings trouble free. We has a general rule of maximum conveyor percentage full by volume be no more than 40% when using hanger bearings with no more that 1mm/m deflection of center pipe. Quantum design all conveyors for full load start up with much consideration given to conveyor speed to eliminate excessive wear. All our conveyors are designed with gland seal packing to protect spherical bearings.

Hopper and Live Bottom Bin dischargers 

Our hopper and Bin dischargers are used when non free flowing materials need to be discharged from hoppers or storage bins. Size and quantity of screws depend on the hopper configuration and the material characteristics. Using multiple screw dischargers can increase volume of hoppers whilst ensuring a positive discharge of material at a controlled out feed. Each screw can be independently powered or interlocked with one or two drive assemblies depending on loading and capacity of the system.

Generally installed with slow speed counter rotating screw flights that can be over locked for maximum discharging capabilities they are variable pitch or variable flight diameters to ensure even material discharge across hopper.

Heating and Cooling Jackets 

All Quantum Screw Conveyors can be fitted with heating and cooling jackets utilizing steam, thermal liquids, refrigerant, water or brine. Heating or cooling can be designed by our process engineers who will recommend the most suitable size and type of conveyor for your production and needs.

Valves, as components of special equipment, are playing an increasingly important role with the vigorous development of power, petroleum, chemical, metallurgy, shipbuilding, and nuclear energy. The developed countries in the world have paid considerable attention to the safety and quality of their manufacture. For various reasons, in February 2003, China started to license the manufacturing of pressure- bearing valves and supervise and inspect the manufacturing quality. In the past, due to the poor control of the valve quality, valve leakage or valve body rupture often occurred, causing serious loss of life and property. This article through the application of radiation detection technology in the field of inspection valve body, in order to effectively control the valve manufacturing quality and improve the economic efficiency of enterprises, played a very good role in promoting. Now, the state has promulgated relevant regulations on the manufacturing quality control of valves and formulated corresponding standards. The standard also mentions the problems of non-destructive testing applied in valve inspection. However, due to the diversity in the size and thickness of valves, radiation inspection has a short history in the field of valve inspection. Therefore, the process of detecting flaws in radiographs is still not mature enough, and there is a great deal of randomness, which can easily cause defects to be missed and cause economic problems. Wasted phenomenon. This article discusses in detail the nature of the radiation, the various effects and attenuation laws of the radiation when penetrating the material, and the principle of radiographing, and in-depth analysis of various factors that affect the contrast, unsharpness, and graininess of the film. Starting from the three major factors affecting the sensitivity of flaw detection, the choices of ray source, focal length, transillumination method, film, backscattering, etc. were studied, and the principles for selecting various transillumination methods were stipulated; according to the general formula of minor defects, combined with the national The ratio of transillumination thickness specified in the standard deduces the minimum number of filming times for various transillumination methods. In the paper, the characteristics of ray equipment and equipment were studied. Different detection methods for transillumination were designed. Rays were detected on defective valves according to the traditional transillumination method and the transillumination technology studied in this paper. The resulting defects were negative films. By comparing and contrasting, it is proved that the contrast film can be obtained with transmissivity according to the detection technology of this article, and the defect film with better contrast, unsharpness, and graininess can be obtained, and the transillumination result can be analyzed and summarized, thus providing the valve manufacturer with the assurance of the inspection quality. , And can improve the economic efficiency of radiation detection technology.

With the development of audio monitoring technology and advances in pickup technology, there are now more and more widely used monitoring pickups, but many users are still confused about what kinds of pickups they should choose for different venues. Then let Guangzhou Sizheng tell everyone what The location should choose what kind of pickup.

1. Bank window/ban window/counter Many of the bank's ban windows are now equipped with bulletproof glass for security purposes. To facilitate communication, it is necessary to install monitoring microphones as communication media at the window. The relationship between the location, the distance between the window and the window is relatively close, and the audio monitoring process always needs to use the recording, so many unnecessary sounds are obviously not picking objects, such as the dialogue at the counter next door. Therefore, as a window-type monitoring pickup can choose directional pickups, directional pickups can clearly pick up a certain range of sound, such as Sizheng COTT-C1 window pickups, COTT-S1 window digital pickups and so on.

If video is stuck and the picture is delayed during wireless video surveillance, this is undoubtedly the most unacceptable. With the development of modernization, the requirements for wireless surveillance are high-definition, real-time, and smooth. We know that because the wireless monitoring system involves several aspects of wireless monitoring equipment, real-time completion is not possible, but if it is well controlled, the delay can be reduced to almost the same as real-time, invisible to the naked eye. Here we talk about how to minimize the delay.

1. Impact on the performance of the wireless video monitoring device: Due to the insufficient CPU processing capability or system response speed of the device responsible for transmission, a delay occurs in the transmission process.

If we want to transmit 1080P/60 frames of high-definition video data over a broadband-limited network without delay, we must first adopt a chip dedicated to video processing, and then, through innovation and reform of the internal architecture and application algorithms of the transmission equipment. Improve the compression ratio of video encoding so that the video data will not be excessively delayed during transmission, and generally can be kept below 40ms.

2, on the impact of decoder performance: the so-called decoder generally refers to the decoder itself or the client for decoding, if the client's host configuration. The quality of the decoder can easily affect the video decoding speed. If the quality is not good, video delay or card screening may occur. However, what needs to be explained here is that in the course of decoding or encoding, the system automatically adds buffering to maintain the fluency of the video, which is also prone to slight delays.

An expensive codec may not be good, and a cheap codec may not be bad. When selecting a codec, it is not a matter of the price, but whether the standard is appropriate or not. It is better to choose a high quality and match. Codec, this is more conducive to the transmission of video data and reduce the delay phenomenon.

3, on the performance of the transmission line: As we all know, a good network cable and a bad network cable, naturally, a good cable transmission efficiency is higher, but prone to delays and other adverse effects is a bad cable, so choose High-quality transmission equipment is an important measure to reduce delays; in the wired transmission, it is naturally a network cable, and in wireless transmission, high-quality wireless transmission equipment must be selected.

4, on the transmission process of relay equipment jump effect: In the transmission process, each jump once, it means to increase the processing time of a transit device, so the more the number of jumps, the greater the time loss caused. Therefore, reducing the number of jumps in designing the transmission route can effectively reduce the delay.

5, on the performance of the switch: When the network traffic becomes larger, the switch and the router's processing time will accordingly longer, and the poor quality of the switch's delay, packet loss rate, backplane bandwidth, switching capacity, packet forwarding Rates and other factors will also be directly reflected in the network transmission process, so controlling network traffic and selecting quality switches are also effective means to reduce the delay.

The time delay of Shenzhen Leian Technology's wireless monitoring equipment is very small, and within a few milliseconds, it is close to real-time.

The difference between unipolar, bipolar, and tripolar switches is that this is a generic problem. It can also be called a single-link, double-link, triple-switch or an open, double-open, or triple-open switch. The button switch, double switch is the two buttons, and so on.

1. The so-called "bit", also known as "link", means that on a panel, there are several switch function modules. "One" means that there is a switch, and "two bits" means that there are two switches that can control two electrical devices separately.

2. The so-called "control", that is, a switch selectively controls several circuits. For example, a dual-control switch, the letters a, b represent the circuit, that is, the process of the switch is to turn on a disconnect b, or turn b off a process. The two lines will not be turned on at the same time, nor will they be disconnected at the same time. In the home, two dual-control switches can be used to control the function of an electric appliance in two places through a certain rule of a certain line, and this function is more widely used in lighting of living rooms and bedrooms.

Explosion-proof duplex and bipolar are two different meanings.

What is the explosion-proof dual-control dual-control switch?

Explosion-proof double switch has three contacts, such as 1, 2, 3, set 1 as a common point, then there are two states: 1-2 pass 1-3 break or 1-2 cut 1-3 pass. Triple switch has four contacts, such as 1, 2, 3, 4, set 1 as a common point, then there are three states: 1-2 pass other break, 1-3 break other break, 1-4 pass other break. Multipole analogy. Like selector switches and the like. The general lighting switch does not have a triple switch.

Explosion-proof two-pole switch is two sets of contacts, there are four contacts, such as 1,2,3,4, there are two states: 1-2 pass and 3-4 pass and 1-2 break and 3-4 break. Three-pole switch has six contacts, such as 1,2,3,4,5,6, there are only two states: 1-2 pass and 3-4 pass 5-6 also pass, the other state is 1- 2 broken and 3-4 broken 5-6 also broken. Multipole analogy. Like circuit breakers, they are called unipolar, bipolar, and tripolar. Can not say two triple.
