[Asia Fluid Network News] diaphragm pump, also known as control, it is mainly used for painting, ceramics and other fields. However, like many pump equipment, the diaphragm pump in the course of the fault occurred, these serious problems can even seriously affect the diaphragm pump and work. Looking for the corresponding fault solution has become the focus of scientific research personnel. The next few will introduce several common diaphragm pump failure and the corresponding solution. Diaphragm pump failure analysis and solutions 1, the diaphragm pump oil failure causes and treatment methods: a, gaskets, seals damaged or too loose; adjust or replace the gaskets, seals. 2, the diaphragm pump flow failure causes and treatment methods: a, into the discharge valve bleed; overhaul or replacement of feed valve; b, diaphragm damage; replacement diaphragm; c, the speed is too slow to adjust failure; overhaul control device , Adjust the speed. 3, the diaphragm pump pressure shortage or increase the cause of the malfunction and treatment: a, pneumatic diaphragm pump pressure regulating valve improper adjustment; adjust the pressure valve to the desired pressure; b, pressure regulator failure; overhaul the pressure adjustment wide; c, pressure gauge Spirit; repair or replacement pressure gauge. 4, the diaphragm pump pressure drop causes and treatment methods: a, fill the valve insufficient oil; repair oil valve; b, insufficient feed or feed valve leakage; overhaul the feed and feed valve; c, plunger seal Oil leakage; overhaul sealing part; d, storage tank oil level is too low; add new oil; e, pump leakage or diaphragm damage; check the replacement gasket or diaphragm. Through the above four kinds of diaphragm pump to explain the common faults, we can find that diaphragm pump failure may be more than one reason, and some may be many, which for the diaphragm pump repair and troubleshooting to increase the degree of difficulty. For the diaphragm pump, although after years of development, already have some use of the foundation, but if you want to further improve the diaphragm pump effect still need the support and help from all walks of life.
