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 does not start after the liquid feed: Screw thick pump has a lot of air inhaled;
Screw thick pump motor steering is wrong;
Screw thick slurry pump feed viscosity is too large. : Check the suction port level is too low, suction tube leaks;
Tune the motor into any two-phase wire; dilute the feed liquid.
Screw thick pump has a trap of vibration or noise, screw thick pump motor and the pump shaft is not the heart;
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 immersed in the 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 Immersion depth, removal of inhaled liquid in the air.
Screw thick pump motor overload, thick pump lift head too much pump;
Screw thick slurry pump viscosity too much.
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 import and export of the opposite position, adjust the gland; replace the filler; intermediate flange port for the suction port.
The main operating data required for selection are:
Screw thick pump conveying medium name, corrosive, abrasive, viscosity, solid content, working temperature;
Operating parameters Flow or flow range, maximum pressure, continuous or intermittent operation;
Installation of the environment Horizontal or vertical, fixed or mobile, connecting the special requirements of the pipeline, explosion-proof protection requirements.
I produced the screw thick pump who contact materials are made of high quality stainless steel metal parts, liner cylinder non-toxic and tasteless credit rubber, the working temperature up to 100 ℃ can be used to transport food syrup and viscosity of 1-1000000 cps Solution of solid particles or capsules of slurry, suspension of the corrosive medium.
Screw thick pump troubleshooting
Screw thick pump start difficult: screw thick pump feed liquid is not full pump, larger frictional resistance.
