Abstract

The invention provides a plunger pump. The plunger pump comprises a motor, a reduction gearbox, a crankshaft box and an acceleration gear module; an input shaft of the reduction gearbox is connected with an output shaft of the motor; a crankshaft is arranged in the crankshaft box; an input end of the crankshaft is connected with an output shaft of the reduction gearbox; an input shaft of the acceleration gear module is connected with an output end of the crankshaft, and an output shaft is connected with an input shaft of a gear pump; and the rotating speed of the output shaft is higher than the rotating speed of the input shaft. The output end of the crankshaft is connected with the input shaft of the gear pump through the acceleration gear module to guarantee that the rotating speed of the input shaft of the gear pump is higher than the rotating speed of the output end of the crankshaft, so that the purpose of accelerating the rotating speed of the input shaft of the gear pump is achieved, the flow of a traditional gear pump can be increased, and the lubricating effect is improved.

Description

technical field [0001] The invention relates to the field of devices for providing emulsions for hydraulic supports during coal mining, in particular to a novel plunger pump. Background technique [0002] The plunger pump is a hydraulic power source designed for the support equipment of the fully mechanized mining face of large coal enterprises, and is the key equipment to realize high production and high efficiency of the working face. Existing plunger pump mainly comprises motor, reduction gear box and crankcase, and the bearing seat that is used to install crankshaft is arranged in the crankcase, and the slide block that links to each other with plunger is done reciprocating slideway; Inside: the crankshaft, which is driven to rotate by the output shaft of the motor after passing through the reduction gear box; installed on the crankshaft journal: the connecting rod, one end of which is connected to the crankshaft journal through the bearing bush, and the other end is con...
