Proper installation of water ring vacuum pump pipeline method

1. Choose a reasonable pipeline scheme
(1) the distance between the vacuum system outlet and the pump inlet is as short as possible;
(2) pipe turn the less the better;
(3) the inlet pipeline should be higher than the pump inlet center line, the outlet pipe should avoid causing greater resistance factors, such as the outlet pipe climb, right Angle turn, etc.
(4) with the import and export pipe diameter should be consistent with the product's import and export diameter, such as smaller vacuum system, import and export with pipe diameter can be small, but not less than 70% of the product's import and export diameter, and the export diameter should be greater than or equal to the diameter of the inlet pipe;
(5) pipeline corner should be smooth transition;
6 water ring vacuum pump inlet pipe of the road to install the valve, how to regulate water inflow and water inflow of how much has influence to the vacuum degree, adjust the water inflow by observing the vacuum table pointer to control the valve, the limit of SK - 0.8 vacuum can reach 0.087, in the working status, because the line is not completely sealed state, vacuum degree at around 0.06 can meet the job requirements.
2. Avoid falling into foreign matters when installing or maintaining pipelines.
3, pipe joints to add sealing gasket, there must be no leakage, leakage phenomenon.
4. Install a vacuum meter at the suction port of the vacuum system to grasp the change of vacuum.
When the vacuum degree reaches the limit, the valve installed on the pipe path of the suction port will produce a lot of noise, called cavitation sound, through the valve to adjust the vacuum degree, when the vacuum degree is high, pressure test blasting detector, open the valve to release an appropriate amount of gas, cavitation sound immediately disappear, the vacuum degree decreases and close the valve.
6. One of the important functions of circulating water is to cool the temperature generated when the vacuum pump works. When the circulating water temperature exceeds 40 ° c, the vacuum degree will decrease.
