The invention discloses a vertical type coal mine pump. The vertical type coal mine pump comprises a pump body, a power mechanism and a forced lubrication mechanism. The pump body comprises a power supply box, a transmission case and a fluid power box which are fixedly connected through bolts in sequence from bottom to top. The power mechanism comprises a crosshead which can be limited inside a guide sleeve in an up-down moving mode. The forced lubrication mechanism comprises an oil conveying pump, an oil suction pipe, an oil drainage pipe, an oil suction hole and an oil drainage hole. The oil suction pipe and the oil drainage pipe are connected with an inlet and an outlet of the oil conveying pump respectively, the oil suction hole is connected with the oil suction pipe and is communicated with the middle-lower portion box body of the power supply box on a power supply box body and the guide sleeve at the corresponding position of the crosshead, and the oil drainage hole is communicated with the oil drainage pipe. The vertical type coal mine pump is small in occupied space and can be arranged conveniently, a plunger moves in the vertical direction, eccentric abrasion due to self-weight can be avoided, operational stability is improved, and meanwhile the forced lubrication mechanism is additionally arranged so that the operating efficiency of the crosshead can be effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of reciprocating pumps, in particular to a vertical coal mine pump. Background technique [0002] A reciprocating pump is a positive displacement pump that relies on the reciprocating movement of a piston, plunger or diaphragm in a pump cylinder to alternately increase and decrease the working volume in the cylinder to deliver or pressurize liquid. At present, it is widely used in high-pressure water jet-assisted rock breaking and coal dropping, underground hydraulic prop liquid supply, high-pressure water jet cleaning, metallurgical descaling, powder metallurgy, ship cleaning and decontamination, foundation engineering, liquid transportation, engineering excavation, and various rubber hoses and metal pipes. Various high-pressure reciprocating pumps are used in pumps for pressure testing of oil field drilling wellhead equipment. [0003] For existing high-pressure reciprocating pumps, especially horizontal ...
