Abstract
A kind of seven plunger emulsion pumps, it has drive mechanism, drive mechanism includes input shaft and bent axle, multiple helical gears are provided with input shaft, helical gear includes the left input helical gear and right input helical gear being arranged in pairs, left input helical gear and right input helical gear occur in pairs, and quantity is identical, and the bent axle helical gear of engagement corresponding with input helical gear is provided with bent axle.Seven plunger emulsion pumps of the present invention are compared to existing five-plunger emulsion pump, and under conditions of identical piston structure and lateral separation, flow is significantly raised, and flow may be up to 1200L/min, meets requirement of the coal mine fully-mechanized mining working to super-flow emulsion pump.Moreover, seven plunger emulsion pumps, because each crank phase difference is smaller, the unit flowed fluctuation of emulsion pump is significantly reduced than existing five-plunger emulsion pump.
Description
Technical field
The present invention relates to a kind of emulsion pump for underground coal mine, more particularly to a kind of intersection of use double helical tooth wheel set
The plunger emulsion pump of formula seven.
Background technology
Emulsion power pack is the essential visual plant of coal mine fully-mechanized mining working, and hydraulic pressure is provided for working surface hydraulic support
Power.In recent years, it is increasing with the complicated mining environment such as China's high working face, super high seam fully-mechanized mining working, in order to full
The high setting load of sufficient high working face hydraulic support, high workload resistance, and fast-moving bracket and safety support demand, to emulsion pump
The technical indicators such as the pressure and flow stood propose higher requirement.At present, the structure of domestic and international high-end large-flow emulsion pump
5 piston structures are used, its flow indicator is mainly 630L/min, can not meet the super high-seam working faces of more than 8m
Requirement to large-flow emulsion pump.
In order to solve super high-seam working face hydraulic system feed flow technical barrier, it is proposed that a kind of seven plungers emulsion
Pump.
The content of the invention
To solve the above problems, the present invention proposes a kind of seven plunger emulsion pump, it has drive mechanism, the transmission knot
Structure includes being provided with multiple helical gears on input shaft and bent axle, the input shaft, and the helical gear is left defeated including what is be arranged in pairs
Enter helical gear and right input helical gear, the left input helical gear and right input helical gear occur in pairs, and quantity is identical, described
The bent axle helical gear of engagement corresponding with the input helical gear is provided with bent axle.
It is preferred that being provided with four input shaft bearing on the input shaft, the input shaft bearing is separately positioned on the input shaft
Multiple crankshaft bearings are provided with two ends and centre, the bent axle, the crankshaft bearing is separately positioned on the two ends of the bent axle
And centre.
It is preferred that the input helical gear and the bent axle helical gear have two respectively.
The input shaft bearing for being preferably provided at the input shaft two ends is located at two helical gear outsides of input respectively, is arranged on
Two input shaft bearing in the middle of the input shaft are arranged between two input helical gears.
The crankshaft bearing for being preferably provided at the crankshaft two end is located at the trunnion of crankshaft two end respectively, is arranged on the song
Crankshaft bearing in the middle of axle is arranged between each two rod journal.
The input shaft bearing in the middle of the input shaft and the crankshaft bearing being arranged in the middle of the bent axle are preferably provided at along axle
To arrangement spaced apart.
Seven plunger emulsion pumps of the present invention are compared to existing five-plunger emulsion pump, in identical piston structure and transverse direction
Under conditions of distance, flow is significantly raised, and flow may be up to 1200L/min, meets coal mine fully-mechanized mining working to super-flow
The requirement of emulsion pump.Moreover, seven plunger emulsion pumps, due to poor smaller, the unit flow waves of emulsion pump of each crank phase
It is dynamic to be significantly reduced than existing five-plunger emulsion pump, by the change to bearings, strengthen overall fastness, it is to avoid
The generation of vibration.
Brief description of the drawings
Accompanying drawing 1 is the side view of seven plunger emulsion pumps, one preferred embodiment of the present invention.
Embodiment
Further exemplary detailed description is done to the present invention below in conjunction with the accompanying drawings.
Referring to accompanying drawing 1, which depict a preferred embodiment according to seven plunger emulsion pump of the present invention.
Seven plunger type emulsion pumps are included on the parts such as crankcase, raising middle flask, pump head, feather valve, safety valve, its drive mechanism
Piston 6 is connected, as its name suggests, it has seven pistons.The drive mechanism of seven plunger type emulsion pumps includes input shaft 2 and bent axle
1, two helical gears are provided with input shaft 2, helical gear includes the left input helical gear and right input helical gear being arranged in pairs, system
Claim the bent axle helical gear 3 that engagement corresponding with input helical gear 4 is provided with input helical gear, bent axle 1.
Four input shaft bearing 7 are provided with input shaft 2, are played a supportive role, input shaft bearing 7 is separately positioned on input shaft 2
Two ends and centre, are each one of both sides respectively, and centre sets two, and scattering device plays a part of sharing to be set on load, bent axle 1
Six crankshaft bearings 5 are equipped with, it is corresponding with input shaft bearing, because bent axle stress is larger, therefore two bearings are respectively set on both sides,
Two are set in centre, bent axle is further supported, it is to avoid generation the problems such as vibration.
The crankshaft bearing at the two ends of bent axle 1 is located at the trunnion at the two ends of bent axle 1 respectively, is arranged on the Crankshaft in the middle of bent axle 1
Hold 5 to be arranged between each two rod journal, space is big and firm supporting, does not influence normal spare and accessory parts to change, actual
Using above achieving very good effect.
In actual use, it is desirable to be spaced a distance arrangement between input shaft bearing 7 between crankshaft bearing 5, it is to avoid
Stress concentration.
It is described above, be only patent of the present invention preferably embodiment, but patent of the present invention protection domain not
This is confined to, any one skilled in the art can readily occur in the technical scope of patent diselosesll of the present invention
Change or replacement, should all cover within the protection domain of patent of the present invention.
