In a hydraulic station, if there are two kinds of pressure requirements, then it can be solved, mainly to see whether the pressure difference between the two required pressures is very large. If the pressure difference is relatively large, the one with high pressure can be determined by the system overflow valve, while the one with low pressure can be realized by adding a pressure reducing valve.
1, hydraulic station on the accumulator, which kind of use more?
Accumulators, in terms of specific types, are gravity type, spring type and inflatable type. If they are used on them, they are more inflatable. This kind of accumulator is composed of four: inflation valve, shell, airbag and limit valve. An inflation valve for inflating the airbag is installed above the shell. Generally, nitrogen is injected into the airbag. Inert gas. In addition, the limit valve is used to limit the expansion position of the airbag to prevent it from entering and leaving the oil port.
2. What are the forms of leakage?
Its leakage forms, specifically speaking, there are mainly three types, namely:
Gap leakage: mainly in the equipment fixed seal or joint leakage.
Power leakage: It is a relatively dynamic leakage that occurs when it carries out production activities.
Porous leakage: refers to the equipment leakage is not at one point, but more porous leakage.
3, requires two kinds of pressure, how to solve?
In a hydraulic station, if there are two kinds of pressure requirements, then it can be solved, mainly to see whether the pressure difference between the two required pressures is very large. If the pressure difference is relatively large, the one with high pressure can be determined by the system overflow valve, while the one with low pressure can be realized by adding a pressure reducing valve.
4. Can the combined sealing gasket be used on the hydraulic station?
It is possible to use a combined sealing gasket, and there is no problem in use. Combined sealing gasket, which is made of rubber ring and metal ring integral bonding and vulcanization, mainly to play the role of sealing. On the material of the rubber ring, oil-resistant nitrile rubber or fluorine rubber is generally used. Also, this seal member is available in both metric and imperial sizes. If used with a ferrule fitting, it can be used to plug the oil port. In the form of sealing, it is generally a static seal rather than a dynamic seal.
