Anonymous users2024-02-16Introduction of the pulse controller produced by Henan Qianhe Automation Technology Co., Ltd. and how it works!
The unique anti-interference technology can ensure stable and reliable operation in the harshest industrial environment, and can completely replace PLC control.
The multi-function shortcut key combined with the four-and-a-half-digit digital tube display can easily modify the control parameters, and the process parameters can be displayed when the controller is working, completely replacing the man-machine interface when PLC control.
The standard instrument housing in the standard B-size size can be mounted directly on the panel of the control cabinet, which not only increases aesthetics, but also directly displays the status of the individual output points.
The external multi-function input port can be applied to the external differential pressure switch control or external switch + timing control, and the network control between the controller and the remote DCS system can also be realized.
The control signal of the ash discharge valve output by the fixed port can be set through the panel to realize the setting of the ash discharge cycle and ash discharge time, and the signal can also be used as the end signal of the cycle cycle for the end of the cycle feedback signal when communicating with the DCS.
The programmable combined output mode can realize the output of the reverse air filter below 18+1 points. By setting the parameters, the combination of M inlet valve + N reverse blowing valve can be combined, and the M+N point switching output can be easily realized. The imported high-power contactless device output can realize the real-time output of the output point, and improve the hysteresis phenomenon of relay output.
Double fuse short-circuit protection output is adopted, and each output point has output indication. Combined with the combination of quick quality judgment keys, it is convenient to judge the fault location of the controller, and realize the output fault judgment in the state of no disassembly. The use of fast fuse fuse can realize the early fuse in the case of output short circuit, and protect the contactless device.
The technical parameters are as follows:
Number of air inlet valves: 1-9 pcs.
The number of blowback valves is 1-9.
Valve interval: 3-999s
Interventricular septum: 3-999s
The number of room cleaning: 1-99 times.
Cycle interval: 1-9990s
Ash discharge cycle: 0-99 times.
Input voltage: AC 220V
Output voltage: AC 220V

Anonymous users2024-02-14The performance of a pulse dust collector depends on the following parameters:
1. Handle gas flow, that is, air volume.
2. The dust removal efficiency is equal to 1 minus the ratio of dust concentration at the inlet and outlet.
3. Pressure loss, the pressure at which the gas passes through the dust collector.
4. The emission concentration of the dust collector, that is, the dust concentration at the outlet of the dust collector.
5. The air leakage rate of the dust collector is (inlet air volume - outlet air volume) inlet air volume.
6. The compressive strength of the shell, the strength of the shell of the dust collector under positive and negative pressure.
The dust collector is inseparable from design and production. Only experienced design analysis and removal of the pin collision conditions and countermeasures of the service section, in the production process to ensure the reliable pressure resistance of the box, low air leakage rate, and the most important filter element filter bag selection and quality control, in order to produce the best dust collector. You can find us in Hwacheon.

Anonymous users2024-02-13A good finger Peiming pulse dust collector should have the following characteristics:
Efficient dust removal: It can effectively deal with the particulate matter in the flue gas and achieve a high dust removal effect.
Strong adaptability: It can adapt to different working conditions and the needs of processing materials, with good stability and reliability.
Simple operation and maintenance: easy to clean, maintain and replace filter bags.
Low energy consumption: low power consumption, saving energy and reducing operating costs.
Environmentally friendly and reliable: It meets environmental protection standards and can reuse the collected dust to reduce the impact on the environment.
The basic principle of pulse dust collector is: using compressed air or gas as the power source, through the switch of controlling the injector, let the compressed air or gas be sprayed onto the filter bag, so that the dust particles on the surface of the filter bag can quickly fall off and be deposited in the ash hopper at the lower part of the filter bag. The whole process is called "blowing".
When the dust in the hopper accumulates to a certain level, the hopper needs to be emptied in order to continue working.
In short, a good pulse dust collector should have the characteristics of high efficiency, strong adaptability, simple operation and maintenance, low energy consumption, environmental protection and reliability, and use the principle of compressed air or gas injection to work.
Instructions for use of HD stand-alone pulse dust collector: 1. HD stand-alone bag dust collector is installed near the mechanical equipment that generates dust, and the user is equipped with metal or plastic pipes and dust collection hoods (can also be designed by the manufacturer) according to the size of the upper air inlet of the dust collector. 2. Before the stand-alone pulse dust collector works, check whether the maintenance door and the flange connection are sealed to avoid air leakage and reduce the dust removal effect. >>>More
A dust collection hood is set up in each ash place, and the dust-containing gas is transported to the dust removal device through the pipeline gas path, in which the dust is collected in the dust removal device after the gas-solid separation is carried out, and the clean gas is introduced into the main pipe or directly discharged into the whole set of equipment into the atmosphere, that is, the dust removal system, and the dust collector is an important part of the system. From the perspective of ventilation and dust removal, dust is all solid small particles that can float in the air for a long time, and is a dispersion system, called aerosol, in which air is the dispersed medium and solid particles are the dispersed phase. A dust collector is a device that separates these small solid particles from aerosols.
