Gear pump common stuck problem and its solution

Gear pump is a type of positive displacement pump, which mainly rely on the work of the pump cylinder and the meshing gear formed by the volume change and movement to transport the liquid or to pressurize the rotary pump. Has now become the transmission, transmission and lubrication of the "good", much market users attention and love. However, users often encounter after a period of time the phenomenon of card pump, in response to this problem should be how to solve this issue for you to interpret one by one Xiaobian. Gear pump common stuck problem and solution (1) gear pump common stuck problem causes of failure: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, the inlet without material or pressure is too low; d, viscosity too High, the pump can not bite countermeasures: a, confirm the direction of rotation; b, confirm the valve is closed; c, check the valve and pressure gauge; d, check the liquid viscosity, low speed operation by the speed ratio of the flow rate is there, , The inflow is insufficient, (2) gear pump failure phenomenon: insufficient pump flow Failure causes: a, suction or discharge valve is closed; b, the inlet pressure is low; c, the outlet pipe plug; d, packing box leak; e, low speed Countermeasures: a, confirm whether the valve is closed; b, check the valve is open; c, confirm the discharge volume is normal; d, tighten; a large number of leaks affect production, should stop running, disassembly inspection; ; (3) Symptoms: abnormal sound failure reasons: a, coupling eccentric or poor lubrication b, motor failure; c, reducer abnormalities; d, gear pump shaft seal security Bad; e, the shaft deformation or wear These are the common pump gear stuck and its solution to the problem, the user should be specific analysis of specific circumstances to identify the problem, to take the right way to deal with countermeasures, I hope the above information to you help.

The ceiling is designed and produced based on gratings, with advantages of light-weighted, beautiful looking, easy installation and strong enough for walking. By hot-galvanizing surface treatment, the ceiling has good property on anti-corrosion and enjoys long life span, no need for painting on surface maintenance. It is widely used in the buildings of cigarette and other industries, large scale stadiums, exhibition centers, commerce facilities, stations, docks, airports, etc.
