Author: admin Date: 2019-08-30 Views: 41
  1. No discharge, but the pump does not run:

Fault (1) The motor is not running; (check the electrical condition of the motor)

(2) The key at the coupling is damaged (replace the key)

(3) Bearing bite (replace bearing)

2. No discharge, but the pump is running:

(1) Motor steering error; (adjust wiring, change motor steering)

(2) No feed; (plus material)

(3) the feed valve is not open; (open the feed valve)

(4) The feed pipe is blocked; (unblock the feed pipe)

(5) There is air in the pipeline or there is air leakage in the pipeline connection (plugging, exhaust)

3. Insufficient traffic:

(1) The motor speed is too low (adjust the motor speed)

(2) Air leakage or damage at the joint of the pipeline; (plugging, repairing the pipeline)

(3) The pressure at the discharge port is too high (the resistance is too large); (reduce the outlet valve and elbow)

(4) Filter screen is clogged (clean and clear)

4.Gasification of the discharged materials

(1) Filter screen, feed valve, feed pipe are blocked; (clean and unblock)

(2) The feed pipe is too thin, the feed pipe is too long, the elbow, too many valves or the filter screen is too thin; (Increase the diameter of the feed pipe, shorten the length of the feed pipe, reduce the elbow, valve: increase Filter aperture)

(3) Feed pressure is too low (high feed)

(4) The viscosity of the conveyed material is too high to exceed its conveying capacity; (reduce the speed; choose a large flow pump)

5. Excessive equipment noise:

(1) Rotor fixed loose (fixed rotor)

(2) The reducer is damaged (repair the reducer)

(3) Loose coupling (replace coupling or key)

(4) High speed (lower speed)

(5) The bearing is damaged (replace the bearing)

(6) The rotor is damaged (replace the rotor)

6. Leakage behind the shaft:

(1) Mechanical seal sealing surface is damaged (replace mechanical seal)

(2) The sealing surface of the mechanical seal is not adjusted properly (refer to the adjustment method of the mechanical seal)
