Abstract

The invention discloses a water liquid pressure self-circulation vacuum unit, comprising a base and a transverse plate. The transverse plate is arranged in the center of the upper end of the base; auxiliary mechanisms are installed on the front and rear sides of the left and right ends of the base; each auxiliary mechanism comprises a universal wheel, a push rod, a slender rod, an end cover and asleeve block; the lower end of each end cover is fixedly connected with the corresponding universal wheel; sleeves are in clearance fit with the upper portions of the outer walls of the slender rods;and the upper ends of the sleeves are rotatably connected with the base through pin shafts. The water liquid pressure self-circulation vacuum unit is scientific and reasonable in structure and safe and convenient to use; through cooperation of the electric push rods, the push rods, the universal wheels, the sleeve blocks, the slender rods and the base, when the whole equipment needs to be moved after use or before use, the universal wheels replace original support legs below the base for supporting, and then, a user can move the whole equipment through the universal wheels, so that the problemthat in the prior art, the whole vacuum unit is large in weight and inconvenient to move is solved.

Description

technical field [0001] The invention relates to the technical field of vacuum units, in particular to a water liquid pressure self-circulating vacuum unit. Background technique [0002] The water ring vacuum unit is composed of a Roots pump as the main pump and a water ring pump as the backing pump in series. The water ring pump selected by the water ring vacuum unit as the backing pump is more advantageous than other vacuum pumps, because it not only overcomes the shortcomings of the limit pressure difference when a single water ring pump is used, and the low pumping rate under a certain pressure, but also is compatible with At the same time, the Roots pump can work quickly and has the advantage of relatively large pumping rate, although the vacuum unit in the prior art can be used. [0003] However, the vacuum unit in the prior art has the problem that the weight of the vacuum unit is too large to be easy to move during use, and it is necessary to manually install or cont...
