What are the reasons for the frequent tripping of high-pressure fans and how to resolve it?
Thread Content
A high-pressure blower is used as the sealing air; the blower has a pressure of 13 kPa, a flow rate of 3.7 cubic meters per minute, and a power rating of 1.3 kW. However, after being put into use, it kept tripping frequently, and the reason for the tripping was the operation of the thermal relay. I installed a pressure gauge behind the three-way valve, and it showed only 7 kPa. The manufacturer said that the pressure of the device without any additional components is 18 kPa – how can there be such a large loss in pressure? Is it because the tee is too close to the outlet? How should this be handled?
The diameter of the fan outlet pipe has been changed, from 50 to 40
