Abstract

The utility model discloses a gas-driven hydraulic pump which can automatically control reversing by using magnetic switches. The magnetic-control automatic reversing control hydraulic pump comprises an oil cylinder, a cylinder end cover, a plunger pole, a cylinder body, a piston, an air cylinder pull rod, a two-position five-pass solenoid directional valve, etc. A magnetic ring is installed on the piston of the cylinder, a magnetic switch is arranged on the air cylinder pull rod, and the two-position five-pass solenoid directional valve is disposed at the right end of the air cylinder end cover. The working process is as follows: the magnetic ring moves along the cylinder piston, when the magnetic ring approaches the magnetic switches on the right and the left sides of the cylinder end cover, the contacts inside the magnetic switches are closed, so that the coil of the two-position five-pass solenoid directional valve is electrified and automatically reversed. The hydraulic pump adopts the magnetic switches as the control components to achieve the automatic reversing of the cylinder of the gas-driven hydraulic pump, and solve the shortcoming with the gas-control gas-driven hydraulic pump, and has the advantages of simple structure, low failure rate, stable performance, reliable operation, etc.

Description

The gas drive oil hydraulic pump of magnetic control automatic reverse control

Technical field

The utility model belongs to oil hydraulic pump, is specifically related to a kind of gas drive oil hydraulic pump that utilizes magnetic switch to control commutation automatically.

Background technique

The gas drive oil hydraulic pump is to be power with pressurized air, and by the continuous linear reciprocating motion of cylinder, driving is leant on stopper rod and constantly changed the cylinder body internal capacity, makes cylinder body constantly suck low pressure fluid, discharges high-voltage oil liquid.Be widely used in static pressure and explosion tests such as flexible pipe, valve, pressurized container, instrument and apparatus testing property and pressure calibration, hydraulic clamp, shaping, boring, shearing, punching press, reinforcing bar crimping.The automatic reverse of cylinder is to promote pneumatic pilot valve by the mechanical type push rod in the gas drive oil hydraulic pump that uses at present, and pneumatic pilot valve control air-flow enters two five-way Pneumatic reversal valves and drives two five-way Pneumatic reversal valve commutations.This control needs mechanical push rods, spring, two pneumatic pilot valves, two five-way Pneumatic reversal valve and many to expose pneumatic tube.This measure design has not only increased the cost cost of gas drive oil hydraulic pump, and rate of fault is higher.For overcoming the shortcoming that cylinder automatic reverse control exists in the present gas drive oil hydraulic pump, the utility model proposes a kind of comparatively desirable cylinder automatic reverse control gear.

Summary of the invention

The purpose of this utility model provides a kind of gas drive oil hydraulic pump with magnetic control automatic reverse control function, thereby makes the gas drive oil hydraulic pump have simple in structure, reliable performance, characteristics that rate of fault is low.

The utlity model has cylinder body 1, cylinder end piece 2, plunger rod 3, cylinder block 4, piston 5, air cylinder tie rod 6 and two five-way solenoid directional control valves 7 etc.The concrete technological scheme that each parts of the utility model connect is: magnet ring 8 is housed on cylinder piston 5, magnetic switch 9 is housed on air cylinder tie rod 6, right-hand member at cylinder end piece 2 is equipped with two five-way solenoid directional control valves 7, is furnished with 4 one-way valves 10 at the upper and lower end of cylinder body 1.The concrete mounting point of these 4 one-way valves is: oil cylinder bottom, left side is furnished with first one-way valve 10-1; Oil cylinder top, left side is furnished with second one-way valve 10-2; Oil cylinder top, right side is furnished with the 3rd one-way valve 10-3; Oil cylinder bottom, right side is furnished with the 4th one-way valve 10-4.For offering some clarification on its working principle, above-mentioned each parts combination can be divided into dynamical element, executive component and control unit three parts: wherein dynamical element is made up of cylinder end piece 2, cylinder block 4 and piston 5; Executive component is made up of plunger rod 3 and four one-way valves 10; Control unit is made up of two five-way solenoid directional control valves 7 that are installed in magnetic switch 9, the magnet ring 8 on the air cylinder tie rod 6 and are installed in cylinder end piece 2 right-hand members.Concrete working procedure is: magnet ring 8 moves right with cylinder piston 5, when magnet ring 8 and right-hand member magnetic switch 9 near the time, the make contact of magnetic switch 9 inside, the coil electricity of two five-way solenoid directional control valves 7 and commutation, cylinder piston 5 and magnet ring 8 beginnings are oppositely to left movement; When the magnetic switch 9 of magnet ring 8 and cylinder end piece 2 left ends near the time, the make contact of magnetic switch 9 inside, the coil electricity of two five-way solenoid directional control valves 7 and commutation, 8 of cylinder piston 5 and magnet rings begin to move right.

Description of drawings

Fig. 1 is the utility model gas drive hydraulic pump structure figure.Fig. 2 is the utility model gas drive oil hydraulic pump gas-liquid fundamental diagram.

Embodiment

Below by specific embodiment the utility model is further described.Magnetic switch of the present utility model is near switch, adopts CS1-U (AC220V10W) type, and two five-way solenoid directional control valves adopt the 4V2-20-08-AC220V type.With reference to accompanying drawing 1, cylinder body 1 assembles with cylinder end piece 2, and plunger rod 3 is connected as a single entity by link and piston 5, and magnet ring 8 is installed on the piston 5.Cylinder end piece 2 and cylinder block 4 are assembled by air cylinder tie rod 6; Magnetic switch 9 is installed on the air cylinder tie rod 6, and two five-way solenoid directional control valves 7 are installed on the right cylinder end piece 2.Concrete working procedure is (with reference to Fig. 1, Fig. 2): magnet ring 8 moves right with cylinder piston 5, plunger rod 3 withdraws from from left side cylinder body 1, produces negative pressure in the left side cylinder body 1, oil cylinder bottom, left side one-way valve 10-1 sealing, left side oil cylinder upper one-way valve 10-2 opens, and sucks hydraulic oil.Meanwhile the other end of plunger rod 3 gos deep into right side cylinder body 1, produces high pressure in the right side cylinder body 1, right side oil cylinder upper one-way valve 10-3 sealing, and oil cylinder bottom, right side one-way valve 10-4 opens, the output high pressure oil.When the magnetic switch 9 on magnet ring 8 and cylinder end piece 2 right sides near the time, the make contact of magnetic switch 9 inside, the coil electricity of two five-way solenoid directional control valves 7 and commutation, cylinder piston 5 and magnet ring 8 beginnings are oppositely to left movement, realize that right side cylinder body 1 sucks hydraulic oil by opening of right side oil cylinder upper one-way valve 10-3, left side cylinder body 1 is exported high pressure oil by opening of oil cylinder bottom one-way valve 10-1.When the magnetic switch 9 in magnet ring 8 and cylinder end piece 2 left sides near the time, the make contact of magnetic switch 9 inside, the coil electricity of two five-way solenoid directional control valves 8 and commutation, 8 of cylinder piston 5 and magnet rings begin to move right.When system needed high pressure oil, the gas drive oil hydraulic pump can be exported high pressure oil automatically continuously.
