Abstract
A hydraulic double action piston pump of the utility model is composed of a valve body, a pump block, a piston, a piston rod, a tapping valve, an imbibing valve, an end cover, a hydraulically operated change valve, a liquid valve, a fuel pump, a fuel tank and a filter, and is characterized in that the double action piston pump appears in a cylinder shape, the valve body is arranged in the middle part, and the pump block is arranged at two ends of the valve body connected by a thread or a flange bolt; the middle part of the piston rod is provided on a change valve, namely two-position and four-way change valve, whose center is passed through by the piston rod having two ends provided with pistons connected by a thread or a flange; the two ends of the pump block are provided with two end covers, which are connected with the pump block by a thread or a flange bolt, and are respectively provided with a tapping check valve connected in parallel on a fuel or a water outlet line, and a suction check valve connected in parallel on a fuel or a water inlet line; and the two-position and four-way valve and a piston drive system are connected in consequence as required.
Description
One, technical field
The utility model belongs to the hydraudynamic drive technical field, more precisely is a kind of double acting piston pump that surges.
Two, background technique
Reciprocating pump is more widely used a kind of mechanical type augmented injection in each oil field at present or oil-conveying device, but this reciprocating pump exist complex structure, volume big, make relatively big and unreliable, the defective such as working life is short that commutates of impact force when difficulty, commutation of processing.
Three, summary of the invention
The purpose of this utility model is to provide a kind of double acting piston pump that surges, and solves the problem that there is the unidirectional supercharging of complex structure in above-mentioned reciprocating pump.Have simple in structure, efficient is high, lift is high, characteristics such as little, safe and reliable, long service life of impact force when easy processing, low cost of manufacture, commutation.
The utility model is made up of valve body, pump block, piston, piston rod, liquid discharging valve, liquid sucting valve, end cap, hydraulicchange-over valve, fluid valve, oil pump, fuel tank, filter.
Pump housing part mainly is made of pump block, piston, piston rod and guiding valve, valve body and suction, liquid discharging valve.During work, when two-piston and piston rod thereof and guiding valve constantly carry out linear reciprocating motion, the cavity of resorption of the epicoele of upper piston and lower piston is produced inhale, row's function, thereby carry out work, the pump housing partly also can adopt the two diaphragm pump structure.
The liquid controlled reversing system is mainly by hydraulicchange-over valve, and two-position four-way valve constitutes.It is characterized in that the two-position four-way valve body is positioned in the middle of two pump blocks, and be formed by connecting with oil cylinder and be that one, guiding valve are that spool and piston rod are formed by connecting and are one.During work, when two-piston moved to the lower end limit position, two-position four-way valve was connected, and pressure oil enters the left chamber of hydraulicchange-over valve, and the oil in right chamber flows back to fuel tank, and spool moves right, the selector valve commutation, and two-piston moves upward.When moving to the upper end limit position, two-position four-way valve is connected, and pressure oil enters the right chamber of hydraulicchange-over valve, and the oil in left chamber flows to fuel tank, and spool is moved to the left, the selector valve commutation, and two-piston moves downward again.
That compared with the prior art the utility model has is simple in structure, the advantage of little, safe and reliable, the long service life of impact force when easy processing, low cost of manufacture, efficient height, lift height, commutation.

Five, specific embodiment
Describe the CONSTRUCTED SPECIFICATION and the working condition of the double acting piston pump that surges in detail below in conjunction with accompanying drawing.As shown in drawings, a kind of double acting piston pump that surges, by valve body 7, pump block 4, piston 5, piston rod 6, liquid discharging valve 1, liquid sucting valve 2, end cap 3, hydraulicchange-over valve 8, fluid valve 9, oil pump 10, fuel tank 11, filter 12 is formed, it is characterized in that double acting piston pump is cylindrical, in the middle of valve body is located at, pump block is located at two ends of valve body, with being threaded or the flange bolt connection, the middle part of piston rod is located at the selector valve that selector valve is a two-position four-way, piston rod passes the center of two-position four-way valve, the two ends of piston rod are provided with and are threaded or piston that flange connects, two ends at pump block are provided with end cap, be threaded with pump block or flange bolt is connected, on two end cap, be provided with the discharge opeing one-way valve separately and suck one-way valve, the discharge opeing one-way valve be connected in parallel on fuel-displaced or the water outlet pipeline on, suck one-way valve and be connected in parallel on oil-feed or the back with water inlet line, two-position four-way valve pursues preface in accordance with regulations with the piston actuated system and is connected.Work as motor start-up, when oil pump was started working, two-piston moved downward.At this moment the epicoele imbibition of upper piston, the cavity of resorption discharge opeing of lower piston.When two-piston moved to the lower end limit position, C, f connected, and e, d connect, and pressure oil enters the left chamber of hydraulicchange-over valve, and the oil in right chamber flows back to fuel tank, and spool moves right, the selector valve commutation, and two-piston moves upward.At this moment the cavity of resorption imbibition of lower piston, the epicoele discharge opeing of lower piston, when moving to the upper end limit position, C, d connect, and e, f connect, pressure oil enters the right chamber of hydraulicchange-over valve, the oil in chamber, a left side flows back to fuel tank, and spool is moved to the left, the selector valve commutation, two-piston begins to move downward again, begins new stroke.
