Abstract
The utility model relates to a two-oil-circuit micro hydraulic pump station belonging to the power output mechanism of the hydraulic machinery field and can be widely applied to the hydraulic machinery field, comprising a motor, an oil circuit integrated block and an oil tank. The inner portion of the oil circuit integrated block is provided with a shaft coupling whose one end is connected with the motor and the other end is connected with a single-way gear pump in the oil tank. The single-way gear pump is connected with an oil filter. The oil circuit integrated block is provided with a hydraulic lock, a pressure adjusting valve and two electromagnetic reversing valves. The oil circuit integrated block is provided with four oil outlets. Two sets of oil circuits can separately control two actuator elements. The utility model has the advantages of high pressure, long service life, no leakage, vibration resistance, water resistance, dust proofing, compact structure, small volume, convenient assembling, convenient repair, etc.
Description
Affiliated field:
The utility model relates to a kind of pair of oil circuit micro hydraulic pumping plant, belongs to the power take-off mechanism in hydraulic machinery field, can be widely used in the hydraulic machinery field.
Background technique:
At present, the micro hydraulic pumping plant of domestic production mostly is a three position four-way directional control valve, can only control an executive component, and can not control two executive components respectively, this is restricted with regard to the application that makes the micro hydraulic pumping plant, because a lot of place needs the micro hydraulic pumping plant to control two or more executive components respectively.
Summary of the invention:
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, and provide a kind of compact structure, volume is little, two cover oil circuits can be controlled two executive components respectively, and have two oil circuit micro hydraulic pumping plants of characteristics such as high pressure, long-life, no leakage, anti-vibration, waterproof and dustproof.
The purpose of this utility model is achieved in that it comprises motor, oil circuit integrated package, fuel tank, in the oil circuit integrated package coupling is housed, one end of coupling links to each other with motor, the other end links to each other with ratchet pump in the fuel tank, the ratchet pump links to each other with oil purifier, hydraulic lock, pressure regulator valve and two solenoid directional control valves are housed on the oil circuit integrated package, and the oil circuit integrated package is provided with four hydraulic fluid ports, and two cover oil circuits can be controlled two executive components respectively.
Described selector valve also can be a manually operated type.
Compared with prior art, the utlity model has following advantage:
1, because the utility model is provided with two selector valves and four hydraulic fluid ports, promptly two cover oil circuits can be controlled two executive components (oil cylinder or motor) respectively, and two cover oil circuits both can use separately, can use simultaneously again.
2, compact structure, volume is little, and is in light weight, energy-conservation reliable.
3, have characteristics such as high pressure, long-life, no leakage, anti-vibration, waterproof and dustproof.
4, hydraulic element of the present utility model adopt German BOSCH-REXROTH technology, and assembling, maintenance, repair are conveniently.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is a fundamental diagram of the present utility model.
Embodiment:
As shown in Figure 1 and Figure 2, it comprises motor 1, oil circuit integrated package 9, fuel tank 4, in the oil circuit integrated package 9 coupling is housed, one end of coupling links to each other with motor 1, ratchet pump 8 in the other end and the fuel tank 4 links to each other, ratchet pump 8 links to each other with oil purifier 7, hydraulic lock 3, pressure regulator valve 12 and two solenoid directional control valves 10,11 are housed on the oil circuit integrated package 9, oil circuit integrated package 9 is provided with A, B, four hydraulic fluid ports 2 of C, D, two cover oil circuits can be controlled two hydraulic jacks 13,14 respectively, both can use separately, can use simultaneously again.Described solenoid directional control valve 10,11 also can be a manually operated type.Fuel tank 4 outsides also are provided with air filter 5 and liquid level rotating mirror 6.Pressure regulator valve 12 can adopt plug-in type or board-like connection.
Working principle of the present utility model: as shown in Figure 3, motor 1 starts, ratchet pump 8 passes through oil purifier 7 from fuel tank 4 oil suctions, high pressure oil is squeezed into two 3-position 4-way solenoid directional control valves 10,11 simultaneously, if the electromagnet of selector valve 10,11 is no electric circuit all, then two selector valves all are in the neutral position, and this moment, high pressure oil was by pressure regulator valve 12 oil sump tanks 4; When the left side of solenoid directional control valve 10 electromagnet is switched on, high pressure oil is by intersecting oil circuit, by the right one-way valve of hydraulic lock 3, the rod chamber that hydraulic fluid port D enters hydraulic jack 13, meanwhile, the internal control oil circuit of hydraulic lock 3 is opened the left side one-way valve, the rodless cavity of hydraulic jack 13 is communicated with, the piston rod withdrawal with fuel tank 4 by hydraulic fluid port C; Otherwise when the right side of solenoid directional control valve 10 electromagnet was switched on, piston rod stretched out.Solenoid directional control valve 10 is controlled stretching out of hydraulic jacks 13 and is withdrawn.
When the left side of solenoid directional control valve 11 electromagnet was switched on, high pressure oil entered the rodless cavity of hydraulic jack 14 by intersecting oil circuit by hydraulic fluid port B, and rod chamber is communicated with fuel tank 4 by hydraulic fluid port A, and piston rod stretches out; Otherwise when the right side of solenoid directional control valve 11 electromagnet was switched on, high pressure oil was by parallel oil circuit, and piston rod is withdrawn.Solenoid directional control valve 11 is controlled stretching out of hydraulic jacks 14 and is withdrawn.
The utility model and computer networking also can realize telecontrol.
