Embodiment Construction

[0015] The present invention will be described in further exemplary detail below in conjunction with the accompanying drawings.

[0016] See attached Figure 1-2 , which describes a preferred embodiment of the five-plunger emulsion pump according to the present invention, which has a cross-type three-point support method based on a herringbone gear pair.

[0017] The five-plunger emulsion pump includes crankcase 1, middle box 2, pump head 3, unloading valve 4, safety valve 5 and other components. In the crankcase 1, there is an input shaft 6 with a helical gear, one end of which is connected to the gear oil pump 7 to provide forced lubrication for the transmission system, and the other end is connected to the motor to transmit the torque through the engagement of a pair of input helical gears 6 through the crankshaft A pair of helical gears 8 decelerate, drive the crankshaft 9 to rotate, and the crankshaft 9 drives the connecting rod 10, the slider 11 and the plunger 12, and ...

Abstract

A five-plunger emulsion pump comprises an input shaft and a crankshaft. An even number of input bevel gears are arranged on the input shaft. The input bevel gears include the left input bevel gears and the right bevel gears. The number of the left input bevel gears is the same as that of the right input bevel gear. Three input bearings are arranged on the input shaft and arranged at the two ends and the middle of the input shaft respectively. Crankshaft bevel gears correspondingly meshed with the input bevel gears are arranged on the crankshaft. Three crankshaft bearings are arranged on the crankshaft and arranged at the two ends and the middle of the crankshaft respectively. The herringbone gear pair transmission technology is adopted, and damage caused by axial component force of a traditional one-sided bevel gear pair to supporting bearings is eliminated; the supporting mode that the middle supporting point of the crankshaft and the middle supporting point of the input shaft are distributed in an intersected manner is creatively adopted; and split bearing covers are adopted for middle bearings, and therefore under the condition that the overall strength is not lowered, the bearings can be more conveniently replaced, and maintenance and repair are facilitated.

Description

technical field [0001] The invention relates to a five-plunger emulsion pump used in underground coal mines, in particular to a cross-type three-point support five-plunger emulsion pump adopting a herringbone gear pair. Background technique [0002] The emulsion pump station, as an essential and important equipment in the fully mechanized mining face, provides hydraulic power for the hydraulic support of the working face and is the heart of the hydraulic system of the entire working face. In recent years, with the increasing number of fully mechanized mining faces with large mining heights in my country, in order to meet the needs of high initial support force, high working resistance, rapid frame movement and safe support of hydraulic supports with large mining heights, hydraulic supports are supplied with liquid The system puts forward very high requirements in terms of pressure and flow, so it needs a high-pressure and large-flow emulsion pump station for matching, and the...
