To introduce the electric butterfly valve to you in detail?
Dongfeng Electric Butterfly Valve Co., Ltd. has arranged detailed introductions on electric butterfly valves for you to read.
The ordinary electric butterfly valve can meet the requirements for vibration reduction of high-speed centrifuge. When the structure of the electric butterfly valve has been determined, the greater the hardness, the higher the critical speed of the system. The electric butterfly valve with too low hardness cannot meet the demand for strength and is easy to be damaged.
Generally, in the design of centrifuge, active vibration reduction and passive vibration reduction are applied at the same time. For high-speed centrifuge, it can be divided into three parts to consider vibration reduction; (1) The main shaft bearing pedestal is designed as a flexible vibration damping type; (2) The whole drive system is flexibly connected with the rack.
(3) The main shaft is flexibly connected with the diesel generator;
In addition to the flexible vibration damping type used in the above three parts, the elastic joint can also be used between the rotating head and the main shaft. There is a layer of silicon rubber between the main shaft and the rotating head of the~RC - z high-speed centrifuge consumed by Sowa, which can further absorb vibration. In addition to vibration isolation, various vibration reduction measures also reduce the critical speed of the rotating system, thus making the operating speed far away from the critical speed. This is why the main shaft of some high-speed centrifuges is very thick and not very long, while the whole system is still working above the critical speed.
