Problems solved by technology

At present, the structure of high-end large-flow emulsion pumps at home and abroad all adopts a 5-plunger structure, and its flow index is mainly 630L / min, which can no longer meet the requirements of large-flow emulsion pumps in fully mechanized mining operations with super large mining heights above 8m.

Embodiment Construction

[0012] The present invention will be described in further exemplary detail below in conjunction with the accompanying drawings.

[0013] See attached figure 1 , which describes a preferred embodiment of the seven-plunger emulsion pump according to the present invention.

[0014] The seven-plunger emulsion pump includes components such as a crankcase, a middle box, a pump head, an unloading valve, and a safety valve. The transmission structure is connected to the piston 6. As the name suggests, it has seven pistons. The transmission structure of the seven-plunger emulsion pump includes an input shaft 2 and a crankshaft 1. There are two helical gears on the input shaft 2. The helical gears include a pair of left input helical gears and right input helical gears, collectively referred to as input helical gears. , The crankshaft 1 is provided with a crankshaft helical gear 3 which meshes with the input helical gear 4 correspondingly.

[0015] There are four input bearings 7 on t...

Abstract

A seven-plunger emulsion pump, which has a transmission structure, the transmission structure includes an input shaft and a crankshaft, and a plurality of helical gears are arranged on the input shaft, and the helical gears include a left input helical gear and a right input helical gear arranged in pairs, and the left The input helical gear and the right input helical gear appear in pairs and have the same number, and the crankshaft is provided with a crankshaft helical gear that meshes correspondingly with the input helical gear. Compared with the existing five-plunger emulsion pump, the seven-plunger emulsion pump of the present invention has a significantly higher flow rate under the condition of the same plunger structure and lateral distance, and the flow rate can be as high as 1200L / min. Mining work faces the requirement of super large flow emulsion pump. Moreover, since the phase difference of each crankshaft is smaller for the seven-plunger emulsion pump, the single-unit flow fluctuation of the emulsion pump is significantly lower than that of the existing five-plunger emulsion pump.

Description

technical field [0001] The invention relates to an emulsion pump used in underground coal mines, in particular to a cross-type seven-plunger emulsion pump adopting a herringbone gear pair. Background technique [0002] The emulsion pump station is an essential and important equipment for fully mechanized coal mining face, which provides hydraulic power for the hydraulic support of the working face. In recent years, with the increasing number of complex mining environments such as large mining heights and extra-thick coal seam fully mechanized mining faces in my country, in order to meet the high initial support force, high working resistance, rapid frame movement and safety support of large mining height hydraulic supports Higher requirements are put forward for the technical indicators such as pressure and flow of the emulsion pumping station. At present, the structure of high-end large-flow emulsion pumps at home and abroad all adopts 5-plunger structure, and its flow inde...
