Diaphragm Accumulator

Product category：Hydraulic drive, control and process control engineering

The diaphragm accumulator uses a high-quality rubber diaphragm to separate nitrogen from the working medium. Featuring a compact structure, excellent sealing performance and sensitive response, it is a stable and reliable energy storage component in hydraulic and pneumatic systems. It uses the rubber diaphragm inside the shell to separate gas from hydraulic oil and is pre-charged with nitrogen at a specified pressure. When the system pressure rises, oil enters the accumulator and compresses the gas inside the diaphragm, achieving energy storage. When the system pressure drops, the gas expands to push the diaphragm and expel the oil, releasing energy.In this way, it fulfills the functions of pressure balancing, energy storage, shock absorption and pressure maintenance, ensuring safe system operation and improving the stability and service life of hydraulic systems.

Bladder-type Accumulator Repair Kit

Product category：Hydraulic drive, control and process control engineering

This bladder accumulator repair kit is fully equipped with charging valve, copper gaskets, rubber support ring, PTFE back-up ring, sealing rings and retaining rings for easy replacement. The sealing parts are made of oil-resistant rubber, featuring high pressure resistance and good compatibility with hydraulic media to realize stable sealing and effectively prevent oil and gas leakage. The PTFE back-up ring can resist extrusion and protect the sealing rings, extending service life under high-pressure working conditions. It matches bladder accumulators of corresponding specifications. When the accumulator suffers air leakage or oil seepage caused by damaged seals, the broken parts can be replaced directly to finish maintenance quickly and reduce downtime. Precision-matched and easy to assemble, it is suitable for daily maintenance of accumulators on hydraulic stations and construction machinery, helping cut the cost of whole-machine replacement.
