Description

Technical Field

[0001] The utility model relates to the technical field of emulsion pumps, in particular to an emulsion pump installation structure. Background Art

[0002] The emulsion pump is used in the coal mining face to provide emulsion for the hydraulic support. The working principle is to drive the piston to do reciprocating motion by the rotation of the crankshaft to achieve liquid suction and discharge. The hydraulic support is used to support the roof and provide a certain space for the coal mining machine to prevent the roof from collapsing. The emulsion is composed of 95% water and 5% oil. The hydraulic support is supported by the hydraulic cylinder for expansion and contraction. For example, a horizontal six-unit reciprocating double-output emulsion pump station proposed in CN23756497U mainly consists of the following components: motor 1, pump, crankcase 2, pump head assembly 3, safety valve 4, unloading valve 5. Motor 1 adopts an explosion-proof motor used in coal mines. The pump adopts a plunger pump, which is mainly composed of a crankcase 2, a high-pressure cylinder sleeve, a pump head assembly 3 and other parts. The crankcase is provided with a crankshaft 21. The rotation of the motor drives the first-stage gear to reduce the drive, which drives the crankshaft to rotate. The rotation of the crankshaft drives the plunger through the connecting rod slider, causing the plunger to reciprocate. Each rotation of the crank can complete the suction and discharge twice, so that the working fluid is sucked in and discharged through the suction and discharge valves in the high-pressure chamber, thereby converting electrical energy into hydraulic energy and outputting high-pressure liquid for the hydraulic support to work. The output shaft of the motor is connected to the input shaft of the crankcase, thereby driving the first-stage gear to rotate. When installing this structure, the motor and the crankcase are generally first directly fixed on the chassis with screws. After each installation, the output shaft of the motor and the input shaft of the crankcase are easily misaligned, making it difficult to connect the two shafts coaxially. Utility Model Content
