I-1B series of thick pump is a single screw volume rotary pump, the pump using eccentric single-screw rotation within the double helix, so that the thick slurry along the spiral groove from the suction port to the discharge port, the pump delivery Features.

malfunction
the reason
Method of exclusion
1. Difficult to start
1 liquid is not filled pump cavity. Frictional resistance larger:
2. The packing gland is too tight and the friction torque between the shaft and packing is too large.
1. Use pipe clamp to move shaft pump spindle 3 ~ 6 turn:
2. Adjust the packing gland.
After starting
No liquid feed
There is a lot of air inhaled:
2 motor steering is wrong: 3 fluid viscosity is too large.
1. Check? Song? Oxime è° what owes 裉 å¸ suction pipe leaks
2. Transfer any two-phase motor into the line:
3 dilute liquid feed.
3. The pump has a lot of vibration or noise
1 motor and pump shaft is not the heart:
2. Pump inhaled air or liquid mixed with a lot of air -
1. Re-adjust the coaxiality:
2. Check? Stanford Ho? Try to rule out the inhalation of air.
4. During operation, the traffic dropped significantly
1. Bushing wear. Clearance increases:
2. Speed ​​reduced:
3. Universal shaft section or shaft damage Transmission failure:
4. Suction pipe into the liquid depth is not enough. There is air into the pump ^
1. Replace the bushing. If necessary? Q Screw:
2. Say spring Lizhao?
3. Downtime maintenance. More Q axis 朕 shaft section or around the axis:
4. 缧 ∥ 敫??? Once immersed into the depth of exclusion inhaled liquid air.
5. Motor overload
1. Head over the pump stroke too much:
2 liquid viscosity is too large:
3. The voltage is too low.
1. Minimize pipe head loss or replace high-lift pump.
2. Dilution of liquid material:
3. Check cough - raise the voltage to the specified value.
6. A large number of shaft seal packing leakage
1. Gland is too loose:
2. Packing wear:
3. Inverse import and export position.
1. Adjust the gland:
2 replacement packing:
3. The middle flange port for the inhalation.
