Abstract

The utility model relates to a hydraulic piston pump for slurry transmission, which comprises a hydraulic cylinder, a working cylinder and ball type check valve control valve sets, and is characterized in that the hydraulic cylinder is arranged at the upper end of the working cylinder and separated from the working cylinder by a cylinder base, and a piston rod is connected with an oil pressure piston and a working piston and passes through a guide sleeve embedded in the center of the cylinder base and a sealing in reciprocating mode. A cleaning cooling liquid inlet and a cleaning liquid outlet are arranged at the upper end of the working cylinder, and a slurry inlet ball type check valve control valve set and a slurry outlet ball type check valve control valve are communicated with the cylinder bottom at the lower end of the working cylinder. The hydraulic cylinder, the oil pressure piston, the piston rod, the working cylinder and the working piston are arranged coaxially. The hydraulic piston pump is compact in structure, can automatically eliminate tiny slurry particles adhered to the inner walls of cylinder bodies, and a cooling effect can prolong service life of the working cylinder and service life of the working piston sealing. By using the double-cylinder reciprocating mode, the working efficiency is high. Appropriate materials are adopted, thereby being abrasion resistant and corrosion resistant, and having long service life.

Description

A kind of hydraulic piston liquid feeding pump
Technical field
The utility model relates to a kind of hydraulic piston liquid feeding pump.
Background technique
At present hydraulic pressure (pottery) plunger liquid feeding pump is widely used, its back and forth (pottery) plunger adopt external pressure packing seal, surface friction drag is big, seal easy to wearly, runs and emits slurry serious, changes frequently; Turnover slurry control valve (group) adopts the plate valve cored structure, to thickness, to contain the particle slurry sealing poor, and the easy pressure break of sealing gasket when starching that high pressure is defeated.More than cause this pump operation cost height.
The model utility content
The utility model provides a kind of compact structure for overcoming the background technique deficiency, hydraulic piston liquid feeding pump safe and reliable to operation.
The utility model adopts technological scheme: a kind of hydraulic piston liquid feeding pump comprises oil hydraulic cylinder, clutch release slave cylinder and ball check valve (number of patent application 201020519553.5) control valve group.Described oil hydraulic cylinder is arranged at the clutch release slave cylinder upper end, separate by the cylinder seat, piston rod connect hydraulic piston and working piston and back and forth navigate within the embedded guide pin bushing in cylinder seat center and sealing in, the clutch release slave cylinder upper end is provided with to be cleaned cooling liquid and imports and exports, the lower end cylinder bottom is communicated with turnover slurry ball formula control valve group; Oil hydraulic cylinder, hydraulic piston, piston rod, clutch release slave cylinder and working piston concentric are provided with.
Working principle of the present utility model: hydraulic piston drives the working piston to-and-fro motion, and when working piston was up, negative pressure made into slurry ball formula control valve open, and pulp ball formula control valve is closed, and slurry sucks clutch release slave cylinder; When working piston was descending, slurry was pressed pulp ball formula control valve is opened, and advanced to starch ball formula control valve and closed, and the slurry pressurization is flowed out.Circulation and so forth.
Compare with background technique, the utility model advantage is: the flexible self-tightening sealing of working piston is reliable, can remove inboard wall of cylinder block automatically and stick small slurry particles, and cooling action can prolong clutch release slave cylinder and working piston seals working life; Adopt cylinder bottom to connect through ball type control valve group, the slurry sealing is reliable, and output steadily deducts the part guiding mechanism, and volume is little and compact;
The utility model hydraulic piston liquid feeding pump adopts suitable material, and energy high-pressure delivery corrosivity, abrasion slurry adopt twin-tub reciprocal, and high working efficiency is beneficial to energy-conservation, and is safe in utilization, and the life-span is long.
Description of drawings
Accompanying drawing is that the utility model partly cuts open structural representation
1. oil hydraulic cylinders, 2. hydraulic pistons, 3. piston rods, 4. cylinder seats among the figure
5. guide pin bushing and seal 6. clutch release slave cylinders, 7. working pistons 8. and clean cooling liquid inlets
9. clean cooling liquid outlet 10. and advance to starch ball formula control valve 11. pulp ball formula control valves
Embodiment
As shown in the figure, the utility model hydraulic piston liquid feeding pump comprises oil hydraulic cylinder 1, clutch release slave cylinder 6 and advances to starch ball formula control valve 10, pulp ball formula control valve 11.Oil hydraulic cylinder 1 is arranged at clutch release slave cylinder 6 upper ends, separate by cylinder seat 4, piston rod 3 passes the embedded guide pin bushing in cylinder seat 4 centers and seals 5 and is connected with working piston 7 with hydraulic piston 2, clutch release slave cylinder 6 upper ends are provided with to be cleaned cooling liquid inlet 8 and cleans cooling liquid outlet 9, and the lower end cylinder bottom is communicated with into slurry ball formula control valve 10 and pulp ball formula control valve 11; Oil hydraulic cylinder 1, hydraulic piston 2, piston rod 3, clutch release slave cylinder 6 and working piston 7 concentric settings.Reciprocating hydraulic piston 2 drives working piston 7 motions by piston rod 3 and sucks, extrudes slurry.
The preferable enforcement that below only is the utility model is sharp, but it does not limit practical range of the present utility model and promptly do not depart from described equal of the utility model claim and change and modify, and still belongs to the protection domain of the utility model.
