Problems

Reasons

Solutions

It does not pump drilling fluids while gauge hand jumps violently.

1. The stock outlet is blocked.

2. The pipeline and instrument leak.

1. Remove the obstruction.

2. Screw or block the leaking point.

It does not pump drilling fluids.

1. Its inlet is higher than the liquid level.

2. The rotating direction is incorrect.

1. Raise the liquid level.

2. Check the rotary direction of electric motor.

Pressure gauge indicates pressure at stock outlet, but it still fails to pump drilling fluids.

1. The outlet pipe has got too much resistance.

2. The propeller is blocked.

3. Rotary speed is not fast enough.

1. Check the pipeline

2. Clean the propeller.

3. Increase the rotary speed.

The flow rate is too low.

1. The propeller is too much worn.

2. The pump silts up.

3. The rotary speed is not fast enough.

1. Replace the propeller.

2. Clean pump and pipe manifold.

3. Increase the speed.

The pump consumes too much power.

1. Its feeding amount is too low or is totally closed.

2. The propeller is worn.

1. Open the valve at stock outlet.

2. Replace the propeller

The bearings overheat.

1. The bearings needs lubricating.

2. Some dirty things exist in bearings。

1. Pour more lubricating cream in.

2. Clean or replace the bearings.
