Abstract
Description
Technical Field
[0001] The utility model relates to a hydraulic system, in particular to a hydraulic system for a garbage compressing device. Background Art
[0002] After garbage is collected, it needs to be compressed. The existing hydraulic systems used in the garbage compression industry generally use a combination of several electromagnetic directional control valves and several DN6 one-way valves with six ports to achieve rapid differential control of the compression cylinder. However, generally, the energy consumption is large, the back pressure is high, and the system temperature rises too fast. The hydraulic system needs to stop for cooling in a short time, resulting in low working efficiency. Content of the Utility Model
[0003] In order to overcome the above deficiencies, the utility model provides a hydraulic system, which can reduce energy consumption, reduce back pressure, and control the temperature rise rate.
[0004] To achieve this purpose, the structure adopted by the utility model is: a hydraulic system, including a compression cylinder group, a loading cylinder group, a motor pump group and a fuel tank assembly. The fuel tank assembly pumps hydraulic oil into the compression cylinder group and the loading cylinder group through the motor pump group. A differential electromagnetic directional control valve is equipped on the oil pipeline of the compression cylinder group, and a loading electromagnetic directional control valve is equipped on the oil pipeline of the loading cylinder group. A pressure control solenoid valve is equipped on the oil pipeline connecting the differential electromagnetic directional control valve and the loading electromagnetic directional control valve to the motor pump group.
[0005] A main pressure valve is arranged between the differential electromagnetic directional control valve and the pressure control solenoid valve.
[0006] A loading pressure valve is arranged between the loading electromagnetic directional control valve and the pressure control solenoid valve.
[0007] An air cooler is also provided.
[0008] Its beneficial effects are: the structure of the utility model is designed reasonably and ingeniously. By using the combination of pressure valves and solenoid valves, on the premise of ensuring the existing installation space and power, the flow rate of the control valve components is enlarged, the energy consumption of the system is reduced, the back pressure is reduced, and at the same time, the air cooler cools down in real time, controls the temperature rise rate, and improves the working efficiency of the hydraulic system.

The fuel tank assembly 10 pumps hydraulic oil into the compression oil cylinder group 1 and the loading oil cylinder group 2 through the motor pump group 9. A differential electromagnetic directional control valve 3 is equipped on the oil pipeline of the compression oil cylinder group 1, and a loading electromagnetic directional control valve 4 is equipped on the oil pipeline of the loading oil cylinder group 2.
