Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum pump bases, in particular to a stably placed liquid ring vacuum pump base. Background Art

[0002] The base of a liquid ring vacuum pump is an important component used to support and fix the liquid ring vacuum pump. It is usually made of strong materials such as steel or aluminum alloy to ensure stable support and protection of the vacuum pump. The base is usually designed to be a flat surface and can be easily installed on a workbench, floor or other flat surface. The design of the base takes into account the weight and stability requirements of the vacuum pump to ensure that there is no instability or tilting during operation. In addition, the base usually also includes a fixing point or bracket for connecting the vacuum pump to ensure the correct installation and position of the pump.

[0003] Most of the liquid ring vacuum pump bases in the prior art are made of metal structures, so they are usually relatively stable when placed on a flat ground. However, the length and angle of the support legs of most liquid ring vacuum pump bases are not convenient to adjust. When the vacuum pump base needs to be placed on an inclined or uneven ground, the stability of the liquid ring vacuum pump base will deteriorate, which can easily cause the base to tilt and cause the liquid ring vacuum pump to fall. The liquid ring vacuum pump base cannot be placed stably, and the liquid ring vacuum pump will produce high-temperature liquid when working. The liquid will flow to the surface of the base, and the long-term erosion of the base's support legs will easily reduce the base's service life. To this end, we provide a stably placed liquid ring vacuum pump base to solve the above problems. Utility Model Content
