Gear pumps and troubleshooting common faults: The phenomenon of a fault: the pump can not nesting: 1, failure reasons: a, rotating in opposite directions; b, suction or discharge valve closed; c, entry no material or pressure too low; d, the viscosity is too high, the pump can not bite material. 2, troubleshooting: a, to confirm the direction of rotation; b, confirm the valve is closed; c, check valves and pressure gauges; d, check the liquid viscosity to the proportion of low-speed running speed of the flow according to whether there is, if flow , is less than inflow. Failure phenomena 2: pump flow less than: 1, failure reasons: a, suction or discharge valve closed; b, low inlet pressure; c, the export pipeline to plug; d, stuffing box leakage; e, speed is too low. 2, troubleshooting: a, confirmed that the valve is closed; b, check whether the valve open; c, to confirm whether the emission of normal; d, fastening; large leak leakage affecting production should cease operation, demolition inspection; e, check the actual speed shaft; Failure phenomenon III: Sound Exception: 1, failure reasons: a, large or poor lubrication eccentric coupling b, motor failure; c, reducer exception; d, seal to install bad; e, axial deformation or wear. 2, troubleshooting: a, to find positive or filling grease; b, check the motor; c, check the bearings and gears; d, check the seal; e, stop the disintegration of inspection. Failure phenomenon IV: overcurrent: 1, failure reasons: a, the outlet pressure is too high; b, melt viscosity is too large; c, seal assembly bad; d, shaft or bearing wear; e, motor failure. Imports of industrial washing machine pump valve 2, troubleshooting: a, check the downstream equipment and piping; b, test viscosity; c, check the seal, appropriate adjustments; d, after stopping checks, hand-drive vehicles are too heavy; e, check the motor. Failure phenomenon V: pump suddenly stops: 1, failure reasons: a, power failure; b, motor overload protection; c, coupling damage; d, outlet pressure is too high, chain reaction; e, pump bite abnormalities; f, shaft and bearing adhesive stuck. 2, troubleshooting: a, check the power supply; b, check the motor; c, open the safety cover, plate vehicle inspection; d, inspection instruments interlock system; e, parking, Reversible drive vehicle to confirm; f, set car identified
