Roots vacuum pump temperature _ reason analysis

vacuum pump is developing very quickly. In recent years, the use frequency increase gradually, but problems inevitably. For example, when using the roots vacuum pump, for some other reason will occur a series of failures, such as the temperature of the roots vacuum pump is too high. How can we solve it? How much is the temperature of the roots vacuum pump?

the temperature of the roots vacuum pump in use process will increase, and may be over temperature. There are several reasons for this phenomenon. Here, we need to perform closed and disassembly for analysis. Let's introduce equipment removal methods and the reason for the motor temperature is too high:

( 1) The motor power, and wide working current, calorific value is big.

( 2) Fan speed is low, small wind pressure, air volume is small.

( 3) The fan blade quantity less, the air volume is small.

( 4) The motor with dirt and oil, reduce the heat dissipation.

( 5) Vacuum pump motor bus voltage of 380 v. Due to the cable voltage drop and uneven distribution of load, motor applied voltage is 365 v, only low voltage vacuum pump and form a large operating current.

these are the cause of the high temperature vacuum pump motor. For avoiding the phenomenon of high temperature vacuum pump motor, regular cleaning the dust on the machine, cleaning machine heat sink, thermal capacity increase; Original fan cover extended 40 cm and installed in it. Axial flow fan, fan cover and the diameter of the same.

1. Before remove the roots vacuum pump, measure and record the rotor portion of the gap, try not to use heavy hammer strike. Remove the components should be kept safe, shall not be damaged.

2。 Stop in detail the cause of the change parts and operating status.

3。 Before disassembly import vacuum pumps, all parts should be cleaned once, and the burr polishing.

4。 No seal gasket or seal of the static sealing surface using inorganic silicon rubber coating processing, and then adjust the rotor local open space according to the list of free space.

in addition, after removal of import vacuum pumps, need to complete installation, but want to stop the leak detection, again after installation, should be timely stop test and function test, when the equipment is normal, can be used.

when the roots vacuum water pump problem, should immediately stop, turn the power off and remove it. This is in order to protect the safety of personnel and equipment. According to the correct method, the temperature is controlled, the temperature is too high. Risk.
