Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of high-power plunger emulsion pump that has accumulator is provided, and its output power is big, long service life.
The utility model is achieved by the following technical solution:
Plunger emulsion pump, comprise motor, support, casing, bent axle, motor and casing are installed on the described support, described crankshaft installed is in casing, the output terminal of described motor is by coupling connection gear speed reducer input shaft, the gear reduction box output shaft connects described bent axle, it is characterized in that: annotate pump before being equipped with one on the described support, an end line shaft of annotating pump before described connects the output terminal of described motor, annotate the pump input end before described and connect accumulator, the described preceding pump output terminal of annotating connects liquid entering hole; The bore of annotating pump plunger before described is a little vestibule towards flow distribution apparatus one side, towards cecum be a macroporous cavity, annotate in the macroporous cavity of pump plunger bore before described accumulator is arranged on.
The line shaft of annotating pump one end before described connects the output terminal of described motor by belt, annotates the pump input end before described and connects described accumulator by flange seal, annotates pump output terminal before described and connects liquid entering hole by flange seal.
The inner formation of described bent axle forced lubricating system, the end cap of described casing is provided with gear pump, and the center of described bent axle is provided with lubricating oil path, and mouth spray is towards the crank throw central position.
Described gear pump is by the oil outlet of pipeline connect box inside crankshaft, described gear pump is by pipeline junctor oil cooler inlet, described machine oil cooler outlet connects the threeway inlet opening by pipeline, two delivery outlets of described threeway connect bent axle inlet and drencher pouring orifice by pipeline respectively, and described threeway is installed on the end cap of casing away from the bent axle input shaft.
Described accumulator is elastic material or the visco-elastic damping material that the perfusion identical with the macroporous cavity shape of plunger bore is shaped.
In the said structure of the present utility model, owing to annotate pump before being equipped with, the preceding pump of annotating is installed on the base, during coal mining, preceding notes pump and entire pump are moved together, and its pressure loss is very little, and can guarantee equally that on the gradient thereby its working pressure finishes imbibition, discharge opeing work, the probability that overwork occurs is less, applied widely, and working life is longer; And lubricating oil is sucked through entering the machine oil cooler cooling after the gear pump pressurization by gear pump, flow into threeway, two outlets by threeway, flow into the lubricated bent axle of bent axle pouring orifice and drencher pouring orifice respectively, thereby bent axle obtains sufficient lubrication and fully cooling, be difficult for Yin Gaowen and break down, simultaneously accumulator is arranged in the macroporous cavity of plunger central through bore, the plunger bore is a blind cavity, need not reserve the hydrostatic support fluid passage, both can guarantee the accumulator effective volume, can be plunger cylindrical fluting installation Sealing or seal combination again and created condition, and then can under relatively large gap, realize the sealability of plunger cavity and plunger, thereby improve the rated working pressure of pump, further guaranteed working life.
The beneficial effects of the utility model are: improve the rated working pressure of pump, good seal performance, the noise of hydraulic planger pump are low, have further guaranteed working life.
