During use, the operator discovered that the drilling rig had a flaw. First, the power of the mud pump hydraulic motor was insufficient when drilling in quicksand layers and deep wells. The mud pump did not work or the pressure was low, which seriously affected the work efficiency/mud pump. Second, the working time was long. Third, the clutch of the mud pump is manual. It is very inconvenient to start the mud pump before each drilling operation. Fourth, the accumulation of debris on the derrick slide can easily cause serious damage to the surface of the derrick and the nylon plate. Wear causes great resistance to the power head moving up and down. Overview of Coal Mine Mud Pump Series Coal mine mud pumps are single-cylinder or double-cylinder reciprocating pumps with different structural forms such as single-acting and double-acting plungers and pistons. Mainly used in geological drilling to supply flushing fluid, cool drilling tools, dilute clay mud and circulate it. It is also used to supply flushing fluid when drilling underground in coal mine tunnel drilling rigs. Cooling drilling tool chip removal. Pressure injection mud can also be used for coal seam fire extinguishing and hole sealing grouting. It can also be used to reinforce and block water grouting in ground engineering and to lubricate the gap between the pipe surface and the soil layer during pipe jacking construction.
