Analysis and Treatment of Common Faults of One - way Pneumatic Diaphragm Pump

One-way pneumatic diaphragm pump is usually used in industry, is now a pump pump a wider range of applications. One-way pneumatic diaphragm pumps rely on compressed air as the driving force, is now the most innovative pump on the market. Although the instrument is good, but there will always be a failure, the following let Xiaobian to analyze the common one-way pneumatic diaphragm pump causes of failure and treatment of it. One-way pneumatic diaphragm pump common cause of failure analysis and treatment methods One-way pneumatic diaphragm pump is operated by air pressure machinery. One-way pneumatic diaphragm pump will be imported from the air inlet pump through the pilot valve and valve assembly alternately change the direction of the air flow to alternately promote the left and right diaphragm to absorb and discharge, while the ball with the material into and out of the open and close To cope with the completion of a work cycle. As long as the pump parts of the closed airtight, the smooth flow, the pump will be able to cycle back and forth to work. The following brief introduction of several common causes of pneumatic diaphragm pump failure analysis and processing methods: 1, in a specific environment, there is intermittent work phenomenon, work and everything is normal. Analysis: valve freeze, confirm the method: dead pump, pour a cup of boiling water on the valve assembly, see the effect. Treatment: 1. Keep the air source dry to minimize the amount of water vapor in the air supply; 2. Change the surrounding environment of the pump so that the temperature rises to prevent freezing; 3. Slow down the operating frequency and also eliminate icing . 2, there is a small amount of material in the muffler gas appears. Analysis of the reasons: 1. diaphragm pressure plate loose; 2. internal and external cavity bolts loose; 3. Diaphragm damage. Approach: You must open the entire pump, cleaning and maintenance, including valve assembly also have to clean and fuel, at the same time find out the reasons for handling. 3, the pump shell material appears. Analysis of the reasons: the material appears at the bolt loose or unbalanced Treatment: Balance tighten the bolt. 4, pump work but no material is shot, or although the material is shot but the pressure is low, the flow is small Cause analysis: The seal is not good. 1 inlet or inlet pipe is not sealed; 2 feed pipe, such as the use of one-way valve, it may not open the valve; 3 material viscosity is too high, the valve ball can not be sealed in time and light weight; 4 valve Ball or valve seat is damaged is not sealed; 5 bolts loose seal; 6. diaphragm pressure plate is not sealed loose; 7. Shaft u-shaped ring, thimble o-ring, .
