Description
Technical Field
The invention belongs to the technical field of hydraulic pump devices, and particularly relates to a valve type flow distribution axial convex disc ball plug emulsion pump.
Background
At present, most working media of hydraulic pumps are mineral oil hydraulic oil, but the use of the pumps in a series of occasions such as mines is seriously hindered due to the characteristics of flammability, pollution, nonrenewability and the like of the mineral oil hydraulic oil. In order to expand the application range of the hydraulic pump or the motor, simplify certain mechanized systems and improve economic benefit, the low-viscosity green transmission medium such as water is used for replacing mineral oil, and the method has great significance for efficient, safe and green exploitation of coal, so that the method is very practical for developing a high-pressure high-flow emulsion pump. The shaft flow distribution and end face flow distribution modes adopted by the traditional hydraulic pump are not suitable for emulsion due to large leakage amount, and the emulsion cannot have better lubricating effect due to poor lubricity, and the required mineral oil amount in the lubricating function is far smaller than the amount of the traditional integral all-mineral oil, so that the mineral oil is still adopted as a lubricating medium, and the hydraulic pump with the novel flow distribution mode is needed. Most of the existing mineral oil hydraulic pumps are complex in structure, large in volume and mass, large in inertia of moving parts and inconvenient to use. The valve type flow distribution axial convex disc ball plug emulsion pump provided by the invention uses mineral oil as a lubricating medium and emulsion as a power medium, and adopts a novel plunger assembly to isolate the mineral oil from the emulsion, so that the traditional flow distribution mode is changed. The liquid suction and the liquid discharge of the emulsion are realized through the distributing valve. The valve type flow distribution axial convex disc ball plug emulsion pump has the characteristics of light weight, small volume, simple structure and the like, meets the requirements of safe and efficient green exploitation, can effectively solve the defects existing in the traditional hydraulic pump, and is a novel product capable of replacing the traditional hydraulic pump.

Detailed Description
For clarity of presentation of objects, technical solutions and advantages of the present invention, a complete and specific description will be given below with reference to the accompanying drawings and the specific embodiments.
As shown in figure 1, the valve-type flow-distribution axial cam ball plug emulsion pump comprises a transmission shaft 1, a cam 4, a movable cylinder 10, a cylinder body 7 and a rear end cover 2, wherein the cylinder body 7 and the rear end cover 2 form a sealed pump body, the cam 4 is driven by the transmission shaft 1, the working surface of the cam 4 is a uniform multi-action inner curve concave-convex surface, the cam 4 is arranged in a thrust ball bearing 5, the cam 4 is arranged in the cylinder body 7 through the thrust ball bearing 5, and the movable cylinder 10 is arranged in the cylinder body 7.
As shown in fig. 4, the movable cylinder 10 includes a movable cylinder body 15, a bellows 17, a movable cylinder cover 16, a plunger 12 and a plunger ball 6, the bellows 17 is disposed in the movable cylinder body 15, one end of the bellows 17 is fixed with the movable cylinder cover 16, the other end is fixed with the plunger 14, an emulsion cavity k is opened on the movable cylinder cover 16, one end of the emulsion cavity k is communicated with the inside of the bellows 17, the other end of the emulsion cavity k is respectively communicated with an emulsion liquid inlet channel d and an emulsion liquid drain channel L, the outer end of the emulsion liquid inlet channel d is provided with an emulsion liquid inlet c, the emulsion liquid inlet channel d is provided with a quick response liquid inlet valve 11, the emulsion liquid drain channel L is provided with a quick response liquid drain valve 12, a lubrication oil cavity j is formed between the movable cylinder body 15 and the bellows 17, the lubrication oil cavity j is communicated with a lubrication oil inlet a through a lubrication oil duct b, the plunger 14 is provided with an internal lubrication liquid channel, one end of the plunger internal lubrication liquid channel is communicated with the lubrication oil cavity j, the other end is communicated with the outer end face of the plunger, the outer end face of the plunger is a concave surface, the plunger ball 6 is disposed on the outer face of the plunger, and the plunger ball 4 contacts with the working disk.
As shown in fig. 2 and 3, the working surface of the cam 4 is a uniform multi-action curved concave-convex surface, the curve is formed by a uniform closed circular arc, and the working surface of the cam 4 is a uniform concave-convex shape.
The invention works in detail by means of the fact that when the motor drives the drive shaft 1, the drive shaft rotates with the motor. Because the working surface of the convex disc 4 is a uniform multi-action inner curve concave-convex surface, the reciprocating motion of the corrugated pipe plunger in the movable cylinder body can realize the liquid suction and liquid discharge of emulsion under the rotation of the convex disc. When the bellows plunger small ball 6 contacts with the concave curved surface of the convex disc, the bellows plunger 8 stretches, when the closed volume of the emulsion cavity k increases, partial vacuum is formed, emulsion enters from the emulsion liquid inlet c, and the emulsion liquid enters into the bellows cavity k through the emulsion liquid inlet channel d by pushing the quick response liquid inlet valve 11, so that the emulsion liquid sucking process is completed; when the bellows plunger small ball 6 is contacted with the convex curved surface of the convex disc, the bellows plunger 8 is compressed, the airtight volume of the emulsion cavity k is reduced, high-pressure emulsion is pressed out, the quick response liquid discharge valve is pushed open to enter the emulsion liquid discharge channel L, and the emulsion liquid enters the hydraulic actuating element to complete the liquid discharge process. When the emulsion cavity k is in the process of absorbing liquid, the airtight volume of the lubricating oil cavity j is increased to form partial vacuum, so that lubricating oil is pushed away from the lubricating oil inlet a through the lubricating liquid channel b to push the one-way valve 8 and enters the lubricating oil cavity j formed by the outside of the corrugated pipe and the movable cylinder to finish the lubricating oil absorbing process. When the bellows plunger 7 is compressed, the piston small ball end moves leftwards to reduce the lubricating oil cavity j, and because the lubricating oil cavity j is reduced, high-pressure lubricating oil is formed by lubricating oil in the cavity, and the lubricating oil enters the contact surface gaps d and g of the plunger and the movable cylinder body and reaches the contact surface m of the piston small ball through the lubricating liquid channels e, h and f in the piston. The bellows plunger 7 is continuously compressed and the pressure in the lubricating oil cavity j is continuously increased, so that a high-pressure oil film can be formed at the contact surface gaps d and g of the plunger and the movable cylinder and the contact surface m of the small ball of the piston, the static pressure support is realized, the two surfaces are prevented from being directly contacted in the moving process, and the abrasion is reduced. Because the lubricating liquid channels e and f in the piston are measured on the plunger, the high-pressure lubricating liquid can push the plunger ball 5 to do rotary motion, and the friction coefficient between the plunger ball and the convex disc is reduced. When the lubricating oil cavity j forms high pressure, high-pressure lubricating oil is adsorbed on the periphery of the corrugated pipe to realize pressure balance between the inside and the outside of the corrugated pipe, and meanwhile leakage of the corrugated pipe is reduced, so that the volumetric efficiency of the pump is improved. Each plunger in the pump will do the duty cycle described above.
The above is a specific implementation mode of the valve type flow distribution axial convex disc ball plug emulsion pump.
