Abstract
This utility model relates to a pneumatic-hydraulic pump, comprises an oil cylinder and a gas cylinder, a delivery one-way valve and an oil suction one-way valve which are integrated with the oil cylinder, a left pump body and a right pump body which are integrated with the gas cylinder, wherein the oil cylinder is connected with the left pump body, a plunger inside the oil cylinder is connected with a cylinder piston inside the gas cylinder, the left pump body and the right pump body are respectively provided with a pilot valve consisting of a lattice housing, a valve needle and a return spring, belonging to the two position bi-pass spring returning mechanical control and change-over valve. The right pump body is connected with a two position five-pass double gas control and change-over valve via which the external air supply is communicated with a left and a right air chamber of the gas cylinder. The utility model has the advantages that the gas signal of the control and change-over valve is directly switched in by air supply with flexible change-over, due to integration of the change-over valve, pilot valve, delivery one-way valve and oil suction one-way valve with the pump body, this utility model is compact in structure, greatly convenient in installation, examination and repair and due to reduction of the exposed conduit wirings, the leakage is hard to occur.
Description
Technical field:
The utility model relates to a kind of pump, specifically a kind of by the air-driven hydraulic pump of the bigger pneumatic piston of diameter to the less hydraulic plunger transmission pressure of diameter, it is applicable to that hydraulic pressure containers such as petrochemical industry, valve, tubing carry out the liquid pressure testing, also can be used as the hydraulic control system pressure source and uses.
Background technique:
At present, known to the pneumatic hydraulic pump structure disperse, each valve of pneumatic pump disperses to put, it is more to connect required exposed conduit road, gives maintenance is installed makes troubles, and is prone to accidents such as leaking termination of pumping; The commutation gas signal of control selector valve comes from the cylinder barrel, easily causes dumb, the incomplete phenomena of commutation.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of compact structure, installs and overhaul conveniently and can not leak the air-driven hydraulic pump of termination of pumping accident.
The purpose of this utility model is achieved in that it comprises cylinder tube and cylinder barrel and the fuel-displaced one-way valve that is connected as a single entity with cylinder tube and oil sucting one-way valve, the left pump housing and the right pump housing that are connected as a single entity with cylinder barrel, cylinder tube links to each other with the left pump housing, it is characterized in that: the plunger in the cylinder tube links to each other with the cylinder piston in the cylinder barrel; The pilot valve that is made of flower cover, needle and Returnning spring is housed in the left pump housing and the right pump housing respectively, and this pilot valve belongs to bi-bit bi-pass spring reset machinery control selector valve; Be connected with two-position five-way double air controlled selector valve on the right pump housing, external air source communicates with left and right air chamber in the cylinder barrel through this two-position five-way double air controlled selector valve.
When external air source entered left air chamber by two-position five-way double air controlled selector valve, cylinder piston moved right, and drove the oil cylinder plunger simultaneously and moved right, and formed vacuum in the oil cylinder, and oil sucting one-way valve is opened, and hydraulic oil is sucked in the oil cylinder chamber.When cylinder piston collides the pilot valve needle, this valve commutation, control the commutation of two-position five-way double air controlled selector valve simultaneously, at this moment external air source enters right air chamber, making cylinder piston drive the oil cylinder plunger is moved to the left, oil sucting one-way valve is closed, fuel-displaced one-way valve opens, pressure oil is transferred out, when colliding the pilot valve needle that is contained on the right pump housing when cylinder piston, this valve commutation, control the commutation of two-position five-way double air controlled selector valve simultaneously, to-and-fro motion so voluntarily acts on when reaching balance on the cylinder piston when the hydraulic fluid pressure of output acts on the oil cylinder plunger with bleed pressure, and pneumatic pump quits work automatically.
The utility model has the advantages that the commutation gas signal of controlling selector valve comes from source of the gas and directly inserts, thereby commutation flexibly; Selector valve, pilot valve, fuel-displaced one-way valve and oil sucting one-way valve and the pump housing are mounted to one, thus compact structure, give to install, maintenance brings great convenience, open conduit wiring reduces, the difficult leakage.
Below in conjunction with accompanying drawing the utility model is explained.
