Screw thick pump start difficult: screw thick pump feed liquid is not full pump, larger frictional resistance. Screw thick pump packing gland pressed too tight, friction between the shaft and packing torque is too large: the use of pipe clamp coupling pump spindle 3 to 6 turn, adjust the packing gland. Screw thick pump start after no liquid material: Screw thick pump has a lot of air inhaled; Screw thick pump motor is not steering; Screw thick slurry pump feed viscosity is too large: Check the suction port liquid level is too low, the suction pipe is Leakage; transfer any two-phase motor into the line; diluted feed. Screw thick pump has a trap of vibration or noise, screw thick pump motor and the pump shaft is not the same; screw thick pump pump pump inhaled air or liquid mixed with a lot of air. Re-adjust the concentricity; check the material level, try to rule out the inhalation of air. Screw thick pump operation, the flow decreased significantly, thick pump screw sleeve wear, the gap increases. Screw thick pump speed reduced. Screw thick pump universal joint or shaft damage transmission failure; screw thick pump suction pipe immersion liquid depth is not enough, there is air into the pump, replace the bushing, if necessary, for the screw; check the power and motor; downtime maintenance , Replace the shaft coupling or around the axis; reduce the suction height, increase the depth of immersion, remove the suction liquid air. Screw thick pump motor overload, thick pump lift more than the pump lift too much; screw thick slurry pump feed viscosity is too large. Screw thick pump voltage is too low, minimize pipe head loss, or replace the high-lift pump. Dilute the feed; check the cause and increase the voltage to the specified value. Screw thick pump shaft seal packing a lot of leakage, thick pump cover is too loose; screw thick pump packing wear; screw thick pump inlet and outlet position opposite to adjust the gland; replace the filler; middle flange port for inhalation mouth. Selection of the main operating data are necessary: ​​screw thick pump conveying medium name, corrosive, abrasive, viscosity, solid content, operating temperature; operating parameters flow or flow range, maximum pressure, continuous or intermittent operation; Type or vertical, fixed or mobile, connecting pipe special requirements, explosion protection requirements.
