Background

The hydraulic station is a hydraulic source device including a hydraulic pump, a driving motor, a tank, a directional valve, a throttle valve, a relief valve, and the like, or a hydraulic device including a control valve. The oil supply is carried out according to the flow direction, pressure and flow rate required by the driving device, the oil supply device is suitable for various machines with the driving device separated from a hydraulic station, the hydraulic station is connected with the driving device (an oil cylinder or a motor) by an oil pipe, and a hydraulic system can realize various specified actions;

the hydraulic station is also called as a hydraulic pump station, a motor drives an oil pump to rotate, the pump pumps oil after absorbing oil from an oil tank, mechanical energy is converted into pressure energy of hydraulic oil, the hydraulic oil is subjected to direction, pressure and flow regulation by a hydraulic valve through an integrated block (or valve combination) and then is transmitted to an oil cylinder or an oil motor of the hydraulic machine through an external pipeline, so that the direction change of a hydraulic motor, the strength and the speed of the hydraulic motor are controlled, and various hydraulic machines are pushed to do work; the hydraulic station used in the market at present can only convey hydraulic oil to the oil cylinder from the oil tank, or convey hydraulic oil to the oil tank from the oil cylinder, and can not recover redundant energy when equipment descends, so that the energy-saving effect is poor.

Detailed Description

As shown in fig. 1, an energy-saving hydraulic station includes an oil cylinder 17, the oil cylinder 17 is connected to a first branch oil pipe 18, a second branch oil pipe 19, a third branch oil pipe 20 and a fourth branch oil pipe 21 through oil pipes 16, the ends of the first branch oil pipe 18, the second branch oil pipe 19, the third branch oil pipe 20 and the fourth branch oil pipe 21 are all connected to an oil tank 1, and valve assemblies are disposed on the first branch oil pipe 18, the second branch oil pipe 19, the third branch oil pipe 20 and the fourth branch oil pipe 21.

The valve assembly on the first branch oil pipe 18 comprises a filter 2 mounted on the first branch oil pipe 18, a non-return valve 3, a non-return valve 7, a gear pump 4, the gear pump 4 being provided with an electric motor 5.

The valve assembly on the second branch oil pipe 19 includes the drop valve 8, the makeup solenoid valve 9 and the flow control valve 11 mounted on the second branch oil pipe 19.

The valve assembly on the third branch oil pipe 20 comprises a check valve 10 mounted on the third branch oil pipe 20, an accumulator 12, a release solenoid valve 13 and a pressure switch 14.

The valve assembly on the fourth branch oil pipe 21 includes the relief valve 6 mounted on the fourth branch oil pipe 21.

The oil pipe 16 is provided with a pressure gauge 15.

The hydraulic station may recover pressure within the system as the lift platform is lowered. The specific operation is as follows: when the lifting platform descends, the oil cylinder 17 retracts under the compression of the lifting platform, the descending valve 8 is electrified and opened, hydraulic oil enters the energy accumulator 12 through the oil pipe 16, the descending valve 8 and the one-way valve 10, when the pressure of the energy accumulator 12 reaches a certain degree, the pressure switch 14 sends a signal, the compensation electromagnetic valve 9 is opened, and redundant hydraulic oil flows back to the oil tank through the compensation electromagnetic valve 9 and the flow control valve 11;

when the lifting platform rises, the release solenoid valve 13 is opened, the hydraulic oil stored in the energy accumulator 12 is pressed into the gear pump 4, the motor 5 rotates, the gear pump 4 is driven to rotate, an oil inlet of the gear pump 4 is pressure oil, the motor 5 can be started easily, when the hydraulic oil stored in the energy accumulator 12 is insufficient, the gear pump 4 sucks hydraulic oil from the inside of the oil tank 1 through the filter 1 and the check valve 3, the hydraulic oil passes through the check valve 7 and the oil pipe 16 and enters the oil cylinder 17, a piston rod of the oil cylinder 17 extends forwards, and when the pressure is too high, the hydraulic oil flows back to the oil tank 1 through.

The energy accumulator of the hydraulic station can recover energy when the equipment descends and output the energy when the platform ascends, and power consumption of the motor can be reduced.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures or equivalent flow transformations made by using the contents of the specification and the drawings, or applied directly or indirectly to other related technical fields, are included in the scope of the present invention.
