Abstract
The utility model relates to a novel oil way. The novel oil way is characterized by comprising an oil tank, a serial pump system, a gear pump, a control valve and an oil cylinder, wherein the oil tank is connected with the gear pump, the control valve is arranged between the gear pump and the oil cylinder, a throttle valve is arranged between the oil cylinder and the control valve, an overflowing valve is arranged on a return oil way of the control valve, the serial pump system is arranged between the control valve and the overflowing valve, and a motor is controlled by the serial pump system to rotate. The novel oil way has the advantages that after the throttle valve is additionally arranged, the return oil way has certain pressure, the descending speed of the oil cylinder is regulated under the load condition according to physical situation, the service life is prolonged, the operation is convenient, and no influence on the personal safety exists; and as the serial pump system can not pump oil by self, the overflowing valve is additionally arranged on the return oil way of the control valve, hydraulic oil can generate pressure when passing through a return oil tank of the overflowing valve, the hydraulic oil can flow in the serial pump system, the serial pump system can run, and the service life of the serial pump system can be prolonged.
Description
Technical field
The utility model relates to a kind of novel oilway.
Background technique
If there is not throttle valve in the oil circuit, in the situation of load, oil cylinder in return because excessive velocities, and unstable, can jolt and shrink downwards, badly damaged coupled sheet metal structural, sheet metal part is caused wearing and tearing, performance to oil cylinder also can cause damage, shortens its working life, in the overweight situation of load, return the vibrations of falling too fast generation, also can damage the operator, as without relief valve, must be by gear pump to its oil transportation, just must additionally add a gear pump, so greatly increased user cost, for addressing the above problem, the spy provides a kind of new technological scheme.
The model utility content
The purpose of this utility model provides a kind of novel oilway.
The technical solution adopted in the utility model is:
A kind of novel oilway, comprise fuel tank, string pumping system, gear pump, control valve and oil cylinder, described fuel tank links to each other with gear pump, be provided with control valve between described gear pump and the oil cylinder, be provided with throttle valve between described oil cylinder and the control valve, the oil circuit of described control valve is provided with relief valve, is provided with the string pumping system between described control valve and the relief valve, the rotation of described string pumping system control motor.
The utility model has the advantages that: added after the throttle valve, owing on the oil circuit certain pressure has been arranged, oil cylinder returns the speed of falling and regulates according to actual conditions under the loading condition, make its slow decreasing, the effective like this wearing and tearing of having avoided sheet metal part, increase its working life, operate conveniently, can not exert an influence to personal safety; Because voluntarily oil suction of string pumping system; therefore the oil circuit at control valve adds a relief valve, and hydraulic oil produces pressure by the relief valve oil sump tank time like this; hydraulic oil will flow in the string pumping system; make its running, when oil circuit pressure was excessive, relief valve will be got through; make it enter fuel tank; keep entering the balance of string pumping system oil circuit pressure, can effectively protect the string pump, increase its working life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, fuel tank, 2, gear pump, 3, control valve, 4, throttle valve, 5, oil cylinder, 6, relief valve, 7, motor, 8, the string pumping system.
Embodiment
As shown in Figure 1, a kind of novel oilway of the present utility model, comprise fuel tank 1, string pumping system 8, gear pump 2, control valve 3 and oil cylinder 5, fuel tank 1 links to each other with gear pump 2, be provided with control valve 3 between gear pump 2 and the oil cylinder 5, be provided with throttle valve 4 between oil cylinder 5 and the control valve 3, the oil circuit of control valve 3 is provided with relief valve 6, be provided with string pumping system 8 between control valve 3 and the relief valve 6,7 rotations of string pumping system 8 control motors.
The utility model has the advantages that: added after the throttle valve 4, owing on the oil circuit certain pressure has been arranged, the speed that oil cylinder falls for 5 times under the loading condition is regulated according to actual conditions, make its slow decreasing, the effective like this wearing and tearing of having avoided sheet metal part, increase its working life, operate conveniently, can not exert an influence to personal safety; Because voluntarily oil suction of string pumping system 8; therefore the oil circuit at control valve 3 adds a relief valve 6, and hydraulic oil produces pressure by relief valve 6 oil sump tank 1 time like this; hydraulic oil will flow in the string pumping system 8; make its running, when oil circuit pressure was excessive, relief valve 6 will be got through; make it enter fuel tank 1; keep entering the balance of string pumping system 8 oil circuit pressure, can effectively protect the string pump, increase its working life.
