Some Preparations before startup Elephant Mud Pump

The service life of reciprocating mud pump not only relates with design and manufacture but also relates with pump’s service condition, operating and maintenance.  Once the triplex mud pump is installed or stopped for a long time, the following preparations must be carried out:

1. Check whether the fuel tank is full of fuel, whether the water tank is full of coolant, and whether the pump is full of lubricating oil

2. The mud pump is connected with the main equipment by a high-pressure water supply pipe.

3. Open the valves in the pipeline system.

4. Check whether the circuit and oil circuit of the diesel engine are normal, whether the instrument is in good condition and whether the oil and water are enough.

5. Check whether the operation handles and switches are in the initial position.

6. If a mud pump package is newly assembled or has experienced long time stoppage, then below preparations must be arranged in advance before startup: 

(1) Check the suction pipe and pump valve, the suction port is not blocked by foreign matter, the pump valve is opened and closed smoothly, the suction pipe is in good sealing condition, and there is no leakage. The suction end of the suction pipe should be 0.3~0.5m below the water, and 0.5m away from the bottom and side wall of the water pool or tank. 

(2) Please check the Net Positive Suction Head (NPSH) should be no more than 2.5m for clean water, and the value will be decreased if the medium is thick mud. In addition, the suction pipe length should be no longer than 5 meters. 

7. Please make sure that specified brands of lubrication oil or grease shall be added into the pump body, all the oil cups and grease fittings until reaching right oil level. 

8. Please make sure that all the components and parts are well tightened, especially the critical connection between piston and crosshead/connection rod. 

9. Please check if the pressure gauge works well, and if its scale is in ‘0’ position when there is no pressure. 

10. Before starting the pump, fill hydraulic 46 wear-resistant hydraulic oil into the oil discharge port of the hydraulic motor

11. Please fully open the pump relief valves before startup so that it is in idle load condition.
