Furthermore, external dust cannot enter the vacuum pump connected to the cavity in the water replenishment tank, so as to avoid the blockage of the cavity in the vacuum pump, which causes the vacuum pump to stop due to the blockage load of the pump head. The first mounting plate 12 and the second mounting plate 10 are assembled together by the first fixing bolt 11, and the closed water replenishment tank cover can be assembled on the side wall 2 of the water replenishment tank. The water replenishment tank body in the utility model includes the side wall 2 of the water replenishment tank and the bottom wall 8 of the water replenishment tank. The third mounting plate 13 and the fourth mounting plate 15 are assembled together by the second fixing bolt 14, and the bottom wall 8 of the water replenishment tank can be assembled on the side wall 2 of the water replenishment tank.

[0046] The utility model provides a closed water replenishment tank in which a water replenishment valve 4 is arranged on a water inlet pipe 3 located outside a side wall 2 of the water replenishment tank, which can prevent organic solvents in the water replenishment tank from corroding the water replenishment valve 4 and extend the service life of the water replenishment valve 4. A ball valve 5 for controlling the flow rate of water in the water outlet pipe 6 is arranged on the water outlet pipe 6.

[0047] In addition, the inner side surface of the top wall 1 of the water replenishment tank and the inner side surface of the side wall 2 of the water replenishment tank form a smooth curved surface, so that impurities in the liquid in the water replenishment tank are not easily retained at the junction of the inner side surface of the top wall 1 of the water replenishment tank and the inner side surface of the side wall 2 of the water replenishment tank. At the same time, the inner side surface of the bottom wall 8 of the water replenishment tank and the inner side surface of the side wall 2 of the water replenishment tank also form a smooth curved surface, so that impurities in the liquid in the water replenishment tank are not easily retained at the junction of the inner side surface of the bottom wall 8 of the water replenishment tank and the inner side surface of the side wall 2 of the water replenishment tank.
