The liquid ring vacuum pump is by the offset impeller rotary motion in the pump chamber so that the working chamber volume changes cyclically in order to achieve the vacuum pump. Its studio consists of a rotating liquid ring and impeller, its structure and working principle and liquid ring compressor is similar. That liquid ring pump pressure regulating hole is what effect? Let Xiaobian tell you. Liquid ring pump liquid ring pump pressure regulating hole is to prevent under-compression and over-compression, it must be set at the pressure regulating valve at the check valve, automatically closed when the lack of compression, automatically open when over compression to avoid excessive power consumption . When the check valve design is not good or poor material leading to check valve failure or damage, the pressure regulator hole not only does not work, but will have adverse consequences. When the pump is working at high vacuum or extreme pressure, less suction gas will occur in the compression section compression is insufficient, the pressure of the liquid outlet will never shut off the pressure back to high-speed return hole, causing a great impact, resulting in serious hydraulic Losses, resulting in a sharp increase in power consumption, pumping speed also has a certain impact. When the inhalation of a lot of gas, and pressure regulating valve can not open the valve, it will cause over-compression, resulting in increased power consumption, but also affect the pumping speed.
