What should I do if there are structural columns of the building on the motor side of the installed centrifugal pump?
Thread Content
Hello everyone. There is such a problem at the site. There are three centrifugal pumps installed on site. The motor cooling fans of two of the pumps are facing the structural columns of the building. They are 15 centimeters apart, as shown in the picture.: Now I want to ask everyone: 1. Is this compliant and will it affect later acceptance? Will it affect the heat dissipation of the motor? 2. If it is not compliant, which standard should I refer to? Please be specific. Thank you all! !
Too close will affect the heat dissipation of the motor. You can refer to this specification: https://wenku.baidu.com/view/799ec435c281e53a5802fffd.html
This post was last edited by Xiao Xixi who repaired the pump on 2020-3-28 23:27. In the future, the non-drive end bearing will be inspected. If there is enough space in the back, it can be inspected without removing the coupling or moving the motor. If there is not enough space in the back, you can only remove the coupling and remove the motor anchor bolts.
The space should be enough for motor cooling.
Change the position of the base to clear the pillars, otherwise it will be troublesome to repair the motor later.
I would like to ask, if there is enough space, do I have to move the motor to inspect the bearing on the pump head? Don't understand?
If the coupling is easy to disassemble, there is no need to move the motor anchor bolts. If it is difficult to disassemble (the puller cannot fit in, and the space at the coupling end is small), the motor anchor bolts must be removed and the motor moved. Generally, it is not necessary to move the motor to repair the non-driving end bearing, but for your pump, you can move the motor when inspecting the non-driving end bearing of the motor.
It should be avoided as much as possible. It is okay to make slight changes and adjust the position when the device is not fully operational. Solve the problem when it can be solved in the early stage. If you leave it for later maintenance, you will be scolded.
The location was not determined at the early stage of design
It affects the air intake of the fan, the motor as a whole will heat up, making subsequent maintenance difficult, the coupling is difficult to disassemble and assemble, and there are too many problems.
