Diaphragm hydrogen compressor for hydrogen refueling station
The main equipment of the gas station includes: diaphragm compressor, high-pressure hydrogen storage cylinder group, hydrogen refueling machine and other auxiliary equipment. The key equipment is the diaphragm compressor. Diaphragm compressor belongs to a special structure of positive displacement compressor, which relies on the deformation of the intermediate diaphragm to change the volume of the gas chamber and achieve gas compression. At the same time, diaphragm compressor belongs to reciprocating compressor in terms of its driving mode. Due to its special structure, the cylinder does not need lubrication, and the sealing performance is very good. The compression medium does not come into contact with any lubricant, so it can compress extremely pure gases, generally reaching a purity of 99.999%, which is more suitable for compressing and transporting various precious rare gases. In addition, for highly corrosive, radioactive, toxic, and explosive gases, diaphragm compressors are particularly suitable. The diaphragm compressor cylinder has good heat dissipation and can adopt a higher compression ratio, so its pressure range is wide, and the highest exhaust pressure can reach 300MPa.
Characteristics of diaphragm compressor in hydrogen refueling station:
1. The overall structure design is reasonable, with smooth and reliable operation, low vibration, low noise, and easy operation and maintenance.
2. The cylinder components adopt a structure without an oil distribution plate, which reduces the difficulty of assembly process; Reduced the sealing surface; Alarm when compressed medium leaks, improving the reliability of the whole machine.
3. The new membrane cavity curve has improved the volumetric efficiency of the compressor and extended the lifespan of vulnerable parts such as membranes and air valves.
4. The built-in oil pump station provides stable pressure, clean quality, and fully cooled lubricating oil for compressor lubrication and oil cylinder operation, and solves the problem of oil leakage in the original external compressor.
5. The highly automated control system fully ensures the safe operation of the equipment.
6. The entire equipment is centralized on a pry mounted chassis, which facilitates the transportation, installation, and management of the equipment.
VRP Series Varnish Removal Oil Purifier
Application
Used in gas and steam turbine, compressor, to remove dissolved and suspended soft pollutants in oil products, sludge and other harmful substances. Avoid turbine failures and expensive oil changes due to paint film problems. When the film is formed, the loss of production is very high. The initial formation of the film is known as a soft pollutant, caused by hot spots in the system, such as bearings, pumps, and high flow on-line filtration. Recent studies have found that the existence of soft pollutants can be divided into dissolved state and suspended state, by removing these soft oxides can avoid the production of paint film. Once the film forms, it will clog valves, filters and other small links, and the life of the oil will be significantly reduced.
The formation of cleaning film will cause the following adverse consequences: valve adhesion, loss of control, resulting in unit failure or startup failure; Filter plugging, limiting oil flow, resulting in oil temperature rise and wear increase; Heat exchange failure, oil temperature rise; Sandpaper surface, increase component wear; Forming paint on the bearing, limiting flow, increasing wear and temperature; Frequent oil changes and system flushes. When the soft pollutants are dissolved in the oil, typically when the oil temperature is above 40℃, they cannot be removed by ordinary mechanical filtration or electrostatic filtration, and these soft pollutants show natural magnetism. For polar absorption, the cooler metal surface "cold spot", i.e. the valve and cooler. When the temperature of the oil is lowered, the thermal stability of the soft pollutants is less than that of the oil, so they are more likely to bake hard on hot surfaces, such as axial shafts.
VRP paint film cleaner. It achieves revolutionary and efficient removal of soft pollutants (dissolved and suspended) from oil products, including gas and steam turbines and compressors under high temperature operation. The warm oil is pumped from the lowest point at the bottom of the tank to the VRP paint film purifier by the equipment's own transfer pump. After cooling treatment (using the thermal stability of the paint film is worse than that of oil), the paint film, particulate matter and moisture are removed by the filter element with wood fiber as the raw material (no need to use ion-exchange resin filter material, greatly saving the cost of use).
Features:
● Increase system reliability and stability. ● No more shutdowns and startup failures caused by paint film.
● No longer need to clean the tank and system flushing. ● Increase jacking oil pressure, more stable bearing temperature.
● Improve the life of oil products, blood additives and system components, such as bearings, valves, seals, etc.
● Great savings can be achieved by avoiding turbine failure and extending the life of oil products. Features:
