What are the main types of bellows accumulators? 1. Hammer accumulator The hammer accumulator stores and releases energy by changing the position of the heavy hammer to the north. The heavy hammer exerts a certain pressure on the hydraulic fluid through the plunger. The accumulator has the advantages of simple structure, hidden pressure, small capacity, low pressure, large size, heavy weight, larg...
As we all know, special valves rely on the pressure and temperature of the medium in the valve as the energy source to drive the valve to work automatically. Its sealing directly affects the performance of self operated control valves. Therefore, to improve the performance of special valves, it is necessary to continuously improve their sealing performance in use. Here are some ways to improve the...
1. For metal corrugated expansion joint Armoured bellows are widely used in various pipeline systems to compensate axial, lateral and angular displacement caused by temperature and pressure fluctuations. The core component of the armored bellows is the bellows, which can carry out pumping, lateral and angular displacement through the deformability and pressure resistance of the bellows, and bear t...
