Description
Technical field
The invention belongs to water pump technology, the idle running protective device of especially a kind of plastic pump.
Background technique
Problem caused by pumping because of cavitation erosion: the reason of pump generation is cavitated mainly has pumping intake piping to hinder big, pumped (conveying) medium gas phase
It is more, fill pump insufficient, the pump intake energy head reasons such as not enough.The harm to pump of cavitating is maximum, and high vibration is pumped when cavitating,
Balance is serious to be destroyed, and will lead to plastics pump bearing, pump shaft damage.
Wherein, filling pump is insufficient causes bearing damage caused by the idle running of plastic pump main shaft relatively conventional, and this technology is led
The personnel in domain, it is necessary for designing a kind of idle running protective device of plastic pump.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, a kind of idle running protection dress of plastic pump is proposed
It sets, which is: bearing damage caused by how avoiding plastic pump from dallying.
