When the pump house due to uneven subsidence of the foundation, etc. and cause the bellows compensator axis offset, vertical concentricity changes; or parts of serious wear, damage, resulting in serious decline in the performance of the bellows compensator and technical and economic indicators and must be disassembled whole machine, repeated repair, replacement, adjustment and partial transformation. The bellows compensator absorbs 70%-95% of the electrical energy into mechanical energy, which is often said to be the efficiency value of the bellows compensator.
It is an important technical index of the bellows compensator, the remaining 30%-5% part is consumed by the bellows compensator itself due to heat, mechanical loss, etc., so this part of the electrical energy is wasted. For ordinary bellows compensator, the efficiency of each increase of 1 percentage point is not easy, the material will increase a lot, and when the efficiency of the bellows compensator reaches a certain value, no matter how much material is added can not be improved.
