Diaphragm pump in the operation should be no abnormal sound, the Department no running, run, drip, leakage phenomena, pressure gauges, control valve work reliably, the performance indicators to meet the specification rated capacity or to meet the production requirements. However, failures can occur due to normal wear and tear or deterioration of parts and components.
　　
Diaphragm pump common fault causes and treatment methods:
　　
Insufficient pressure diaphragm pump or increase the cause of the malfunction and treatment
　　
1, pneumatic diaphragm pump pressure regulator improperly adjusted; adjust the pressure valve to the desired pressure 2, the pressure regulator valve failure; overhaul the pressure adjustment wide 3 pressure gauge spirit; repair or replace the pressure gauge
　　
Pressure drop of diaphragm pump causes and remedies
　　
1, fill the valve insufficient oil; repair valve 2, insufficient feed or feed valve leakage; overhaul the feed conditions and feed valve 3, the plunger seal oil leak; overhaul the seal part 4, the reservoir tank oil is too low ; Add new oil 5, the pump body leak or diaphragm damage; check the replacement gasket or diaphragm
　　
Membrane pump failure causes and treatment methods
　　
1, into the discharge valve bleed; repair or replace the feed valve 2, the diaphragm is damaged; replace the diaphragm 3, the speed is too slow, adjust the failure; overhaul the control device, adjust the speed.
　　
Cause of diaphragm valve oil leakage and its treatment
　　
Gasket, ring damaged or too loose; adjust or replace the gaskets, seals.

Polyacrylamide

Polyacrylamide (PAM) is a water-soluble polymer, which is insoluble in most organic solvents, has good flocculating properties, can reduce frictional resistance between liquids, Can be divided into non-ionic, anionic, cationic and amphoteric four types.

When PAM is used for flocculation, it is related to the surface properties of the species being flocculated, especially the potential, viscosity, turbidity, and pH of the suspension. The kinetic potential of the particle surface is the reason for particle inhibition. Can reduce the potential and condense.

Granular polyacrylamide flocculant cannot be directly added to sewage. It must be dissolved in water before use, and its aqueous solution are used to treat sewage.The water in which the particulate polymer is dissolved should be clean. Generally tap water is suitable for formulating polymer solutions. Strong ACID, strong alkali, high salt water is not suitable for preparation. Water at room temperature is ok, no necessary to heat. Dissolution is slow when the water temperature is below 5 ° C. Increasing the water temperature will accelerate the dissolution rate, but above 40 ° C will accelerate the degradation of the polymer and affect the use effect. The solution concentration is recommended to be 0.1% -0.3%.
