The working pressure of the product is 01MPa~07MPa, and the medium is air that has undergone oil and water removal treatment. The filter press does not require irrigation, and the self suction discharge machine stores wastewater. Automatic induction tank: weighing, high voltage, grounding air pressure. Automatic pressure maintaining, mechanical pressure maintaining, malfunction. Product research and development, manufacturing, and professional production. Compact region and structure, small size, and light weight. Easy to install and maintain. The development and self-reliance of our country have brought our goals to a new level. The scope and ability of self operated pressure regulation in China have reached the level of organizational capability. The range and capability of self operated pressure regulation in China have reached the advanced level of foreign countries, which is based on China’s satisfaction factors for liquids, oils, and other products. China has adopted a comprehensive level of adaptability to water technology, adapting to high flow rates and low pressure losses. The improvement and degree of adaptability have also successively aroused the trust of the country< Eod>.

The compensator design method is applied in some deep sea equipment,
The figure below shows the rolling diaphragm used for its pressure compensator and the basic structure of the pump station.

Rolling diaphragm in practical applications on deep sea submersibles
The pressure compensator has a design pressure of 18 MPa, a flow rate of 1 L / min, and a maximum working water depth of 8000 m.
The hydraulic equipment was prepared before the test in a 90 MPa pressure cylinder with a test pressure of 78 MPa.

Through the experiment, GENERAL SEALTECH LIMITED established a mathematical model of compensation pressure, which was obtained through analysis.

1. Asymmetric actuator action is the main factor causing compensation pressure fluctuations;

2. The process of compensating pressure fluctuation caused by the action of asymmetric actuator is mathematically modeled, and the peak value of compensating pressure fluctuation at steady-state operating point and the peak value of pressure difference inside and outside the rolling diaphragm are obtained, and it is pointed out that the inner diameter of compensator is affecting pressure fluctuation. The main structural parameters of the peak value and the peak value of the internal and external pressure difference, which should take a large value;

3. According to the rolling diaphragm strength theory, according to the design criterion that the peak pressure difference inside and outside the rolling diaphragm must be less than the safe working pressure of the rolling diaphragm, the boundary constraint of the inner diameter of the compensator is derived, and the value range of the inner diameter is obtained, combined with the actual Design requirements and processes, the method of determining the inner diameter of the compensator;

4.Based on the key structural parameters of the inner diameter of the compensator, some compensators for deep-sea equipment were designed and tested by a large number of pressure cylinders. The actual use proved the feasibility of the design method.
