Stainless steel vacuum pump closed-circuit circulation system sometimes can not lift the paste, which is very likely due to its low speed, which requires us to understand what causes the low speed.

1. Due to human factors, quite a number of users are randomly equipped with another motor to drive due to the damage of the original motor. As a result, the flow rate is low, the lift is low and even the water can not be pumped.

2. There are many large-scale stainless steel vacuum pump closed-circuit circulation system using belt conveyor. Due to long-term use, the belt is worn and loose, resulting in slipping phenomenon, thus reducing its speed.

3. Improper installation, too small center distance between the two pulleys or the two shafts are not parallel, the tight edge of the drive belt is installed on the top, resulting in too small wrap angle, calculation error of two pulley diameter, and large eccentricity of two shafts in the closed-circuit circulation system of stainless steel vacuum pump driven by coupling drive, etc., all of which will cause the speed change of the closed-circuit circulation system of stainless steel vacuum pump.

4. Mechanical failure of stainless steel vacuum pump closed-circuit circulation system itself, loose fastening nut between impeller and pump shaft or deformation and bending of pump shaft, resulting in excessive impeller movement, direct friction with pump body, or bearing damage, may reduce the speed of closed-circuit circulation system of stainless steel vacuum pump.

5. If the power machine is not maintained, the motor will lose its excitation due to the burning of its winding. The change of winding turns, wire diameter and wiring method in maintenance, or the factors not completely eliminated during maintenance will also change its speed.

For the stainless steel vacuum pump closed-circuit circulation system speed is too low to understand the reason, in the future also convenient for their own use, at the same time will bring greater help for themselves, for the above knowledge for you to introduce this.
