In fact, a hydraulic station is a type of hydraulic device whose main purpose is to complete various prescribed actions. The main structure of a hydraulic station includes a hydraulic pump, motor, and oil tank, which play a very important role. Secondly, it also includes directional valves, namely valves for adjusting direction and throttle valves, which are valves that change the throttling section and length. The structure of the throttle valve is relatively simple, and if there are minor issues, the manufacturing and maintenance costs are also very low. However, throttle valves also have some drawbacks, such as poor sealing, but they exist in hydraulic stations and do not affect the normal operation of hydraulic stations. In addition, it also includes hydraulic source devices or control valves such as relief valves. Due to the combined action of these complex structures, hydraulic stations can perform their specified functions. The situation of insufficient pressure in the hydraulic system is believed to be frequently encountered, because any hydraulic pump station will have more or less insufficient pressure problems after being used for a long time.
Factors affecting insufficient pressure in hydraulic stations
1. Hydraulic oil pumps, such as quantitative vane pumps, variable vane pumps, variable piston pumps, internal gear pumps, and external gear pumps, as well as damaged oil cylinders or motors with significant internal leakage.
2. There is an issue with the design of the integrated channel block. This is completely a matter of the level of ability of hydraulic system designers, and good hydraulic system design engineers will not encounter such problems.
3. Hydraulic oil pumps installed in hydraulic systems, such as quantitative vane pumps, variable vane pumps, variable piston pumps, internal gear pumps, or external gear pumps, have excessively low speeds.
4. The overflow valve is damaged. In fact, the reason for all the hydraulic oil overflowing back into the mailbox after passing through the relief valve is the same as before, either repaired or replaced.
5. The hydraulic oil level in the oil tank is too low. According to the formal usage requirements of hydraulic systems, add oil to the specified height on the oil level gauge of the tank when draining.
