Multifunctional water pump control pneumatic valve used in pumping station automation reconstruction 3)

the current water level, the two pumping stations, double speed pneumatic valve, pneumatic valve manually, and a miniature pump export slowly-closing butterfly check pneumatic valve pneumatic valve equipped with urban station pressure manually, through several years of operation, pump discharge, the main problem is: double speed pneumatic valve opening and closing is inflexible, electromagnetic four-way pneumatic valve failure rate is higher, can't meet the requirements, run automatic pumping station; Slowly-closing check pneumatic valve stroke, debugging is difficult to grasp, this often can appear slowly-closing check pneumatic valve closed lax pump reverse phenomenon, such as hydraulic maintenance and repair more troublesome. L years, the company, rather than the judicial pneumatic valve manufacturing co. , LTD. Zhuzhou south hebei pumping station 'multi-functional water pump control pneumatic valve', the ideal to solve these problems, improve the production safety and the reliability of water supply, automatic operation of the pumping station. A multifunctional water pump control pneumatic valve profile JDX multifunctional water pump control pneumatic valve series, the whole process is a new automatic water supply pneumatic valve, open the automatic centrifugal pump to realize slowly open, when the pump is going to two-phase closed quickly, alleviate closed, in order to prevent the medium pipeline, pneumatic valve can replace the pump discharge pipe pneumatic valve operation, double speed pneumatic valve, slow close check pneumatic valve pneumatic valve water hammer eliminator. Secondly, the design of a few big characteristics. Pneumatic valve in the main sliding plate and the pneumatic valve plate pneumatic valve opening can change the form with the flow, it is close to zero is close to the flow of the ideal, to eliminate water hammer. 。 Control and the diaphragm chamber design, avoid resistant control piston cylinder cavity due to the existence of the circuit breaker failures. At the same time reduces the operation pressure, diaphragm material has reinforced nylon fiber reinforced neoprene mesh first, action, life can be put into. 。 Swing check pneumatic valve power consumption than to reduce the main pneumatic valve plate, a streamlined design, for the wind resistance coefficient. Significantly higher. Low resistance swing one-way pneumatic valve coefficient spacious seat reduce weight %. 。 Easy maintenance, use a wild type pneumatic valve cover, but does not remove the flange, pneumatic valve components can be deleted. Third, the operating data of pump model Sh A kw motor rated speed r/min A of ten thousand head of flow test cases of the 224 m3 / h:. Automatic control of pneumatic valve open to seconds, automatically shut down time Seconds. 。 In minutes, and when the pump to pneumatic valve open. Four, the use of the results of our water company and the product of months, more than the total number of hours trouble-free, normal operation show that the running speed of the pneumatic valve is very stable, in years. 。 Meet the requirements of brake under the centrifugal pump to start, to ensure the pump light load, motor start without electricity, liquid, the pump can be directly to start and stop control, not only solved the pipeline caused by sudden power blackout medium for water hammer pump system produces the influence of the media in return, but also greatly reduces the labor intensity. 。 To eliminate water hammer test result is satisfactory, close the pneumatic valve when the pump stop smoothly, without noise, vibration, pneumatic valve closed tightly, because the water completely in control of the pneumatic valve control, so there is no special management.
