The spray pump is a large-flow high-pressure spray dust suppression pump station for large and medium-sized coal mining machines and roadheaders. It can meet the requirements of spraying inside and outside of the coal mining roadheader, and supply the pressure water required by the spray system to achieve spray dust suppression. .
The spray pump is a horizontal three-plunger reciprocating pump. It is driven by a three-phase AC four-stage explosion-proof motor, which reduces the speed of the first gear to drive the crankshaft of three cranks to rotate, and then drives the plunger to reciprocate through the connecting rod and slider, so that the working fluid is sucked in by the suction and discharge valve group And discharge, so that the electrical energy is converted into hydraulic energy, and the pressure water is output for use by the shearer.
The spray pump unit is mainly composed of a motor, a coupling, a spray pump (including a safety valve, an overflow valve) and a bottom trailer.
