6 Common Faults Of Directional Drilling Mud Pump

January 7, 2022

During the use of the horizontal directional rotary mud pump, various problems may occur, and these 6 types of failures are the most common.

Fault 1: The pump does not absorb water

Sometimes, during the use of the mud pump, the mud pump does not absorb water due to insufficient filling water and the inability to discharge the air in the pump. In addition, the reason why the mud pump does not absorb water is also caused by the leakage of the suction pipe and the front The gap between the liner and the impeller is too large; when this happens, after finding the cause of the phenomenon, it is necessary to take corresponding measures to solve the problem. The measures include continuing to infuse the water diversion, check the pipeline, and observe Whether there is air leakage, adjust the gap between the impeller and the front liner.

Fault 2: Low water pressure and flow rate

In addition, if the gap between the impeller and the front liner is too large (or the impeller liner is worn), it is also easy to cause the failure of the water pressure and flow rate. This is also one of the common failures of the mud pump. Adjust the gap between them (or replace the impeller and liner). In addition, the reasons for the low water pressure and flow include the air in the pump and the tightness of the clutch. The corresponding solution is to exhaust the air in the pump. Empty, adjust the clearance of the clutch friction plate.

Fault 3: Slow water supply

The slow water supply of the pump is also related to the large gap between the front liner and the impeller. In addition, the failure of the water outlet pipe to seal the air and the full emptying also cause the slow water supply failure of the pump. Therefore, it is necessary to adjust the water outlet pipe. Install the vacuum device.

Fault 4: Water pump vibration

When the pump shaft is not concentric with the diesel engine (motor), it will cause the mud pump to vibrate. Therefore, it is necessary to adjust its concentricity; in addition, the impeller imbalance and bearing damage will also cause the vibration of the water pump. If the impeller is unbalanced, it is necessary to perform a balance test on the impeller. If the bearing is damaged, only the bearing needs to be replaced.

Fault 5: The impeller journal wears quickly

The impeller is one of the most important parts of the pump product. When the high pressure water pump has low lift, misaligned packing, misalignment of the pump shaft and the back cover, etc., the wear of the impeller journal will continue to increase, so it is necessary to adjust the high pressure. The high pressure pump and packing of the mud pump head are replaced. The concentricity of the pump shaft and the back cover can be adjusted appropriately.

Fault 6: Pump wears quickly

When construction is carried out in a place with a poorer construction environment, it will be added to a place with a poorer construction environment, which will increase the wear of the pump. Therefore, it is necessary to maintain a good construction environment to cause this phenomenon The reasons for this also include the long transmission distance and long water inlet pipe, which requires adding an afterburner and shortening the length of the water inlet pipe to reduce cavitation.

There are many common faults of the mud pump, which requires careful inspection of the various parts of the mud pump before construction. Pay more attention to the three processes of startup, operation and shutdown, and operate in accordance with the prescribed procedures to reduce The probability of mud pump failure.
