Description

Technical Field

[0001] The invention belongs to the technical field of integrated hydraulic station systems, and in particular relates to an integrated hydraulic station system based on intelligent control. Background Art

[0002] Hydraulic station system is widely used in various hydraulic machinery, especially those scenarios where the main machine and hydraulic device can be separated. It has the characteristics of wide application, high efficiency and simple structure, and is an indispensable electromechanical device in industrial production.

[0003] In the operation of traditional hydraulic station system, the following problems may exist: 1. The traditional hydraulic station system lacks intelligent control and cannot effectively adjust the valve closing speed, resulting in sudden changes in liquid flow rate and hydraulic shock.

[0004] 2. Braking problem of high-speed moving parts: The system has insufficient braking control over high-speed moving parts such as the cylinder piston, and inertial impact is generated when the piston stops suddenly.

[0005] 3. Insensitive component response: The hydraulic components in traditional systems react slowly and cannot respond to pressure changes in time, resulting in pressure shocks.

[0006] 4. Lack of buffer devices: There is usually no effective buffer device in the system to absorb the impact energy, which aggravates the impact of hydraulic shock.

[0007] The above problems may cause the oil pressure in the hydraulic system to rise sharply instantly, forming peak pressure, damaging components, affecting the stability and reliability of the system, generating vibration and noise, etc., leading to loosening of connectors, oil leakage, and changes in the pressure regulating pressure of the pressure valve, affecting the stability and reliability of the hydraulic system; and may interfere with normal work. Components such as pressure relays may send out error signals due to hydraulic shock, interfering with the normal operation of the hydraulic system and even causing accidents, resulting in poor working stability and reliability of the hydraulic system.

[0008] To this end, we propose an integrated hydraulic station system based on intelligent control. Summary of the invention
