The fire pump is an important component of the firefighting system, and the mechanical seal is an important component of the fire pump. It is the key to ensuring the tightness of the pump, but unfortunately, the mechanical seal of the fire pump often leaks seriously.
There are several reasons for the serious leakage of the fire pump mechanical seal. Firstly, the quality of the mechanical seal itself is not good enough. If the seal material is not selected correctly or the processing technology is not mature, it will cause leakage. Secondly, the installation of the mechanical seal is not correct, which will also cause leakage.
In addition, the medium in the pump is not clean enough, and the foreign matter in the medium will cause the mechanical seal to wear and tear, and finally cause leakage. The wrong operation of the pump will also cause the mechanical seal to leak. If the pump is operated at a pressure that exceeds the rated pressure of the mechanical seal, the mechanical seal will be damaged and leakage will occur.
In addition, the medium temperature of the pump is too high or too low, which will cause the mechanical seal to be out of balance and cause leakage. The pressure of the medium is too high, which will also cause the mechanical seal to leak.
In summary, the serious leakage of the fire pump mechanical seal may be caused by the quality of the seal itself, incorrect installation, unclean medium, wrong operation, and high or low temperature and pressure of the medium. Therefore, in order to avoid leakage, we need to select the right seal material and install it correctly, keep the pump clean, operate it correctly and prevent the temperature and pressure from exceeding the rated value.
