重庆升降机真空水箱充水法对于不设底阀的小型泵站，可采用真空水箱充水法。真空水箱是用铁皮焊制的封闭型水箱，其容积至少为进水管容积的3倍，水箱安装的位置应尽可能靠近水泵，水箱底高也应略低于水泵的轴线。根据升降平台维修人员的介绍，真空水箱的高度一般为水箱直径的2倍。
Wenzhou lifting platform Water Act for filling the vacuum tank bottom valve is no small pumping stations, water filling method can be used vacuum tank. Vacuum tank is welded with a metal closed type water tank, its volume is at least 3 times the volume of the inlet pipe, the location of the tank should be installed as close to the pump, the tank should be slightly lower than the high end of the pump axis. According to reports, the height of the vacuum tank Wenzhou lifting platform maintenance staff is generally twice the diameter of the tank.

升降平台水泵启动前，先将水箱灌满水进行密封。水泵启动后，水泵从真空箱进水，由于水箱水位下降致使水箱内形成一定的真空，进水池中的水就会在大气压的作用下，经进水管进入水箱中，从而形成水的循环，使水泵开始正常运行。这种充水方法水力损失小，泵站效率高，技术人员劳动强度低，启动简便，且利于实现水泵机组的自动化控制。
Wenzhou lifting platform before the pump starts, the first tank filled with water seal. After the pump starts, the water pump from the vacuum tank, the tank water level drops due to resulting in the formation of a vacuum in the tank a certain, water inlet will pool under the influence of atmospheric pressure, through the inlet pipe into the tank, thereby forming a water circulation, pump begins normal operation. This method of small water-filled hydraulic loss, high efficiency pumping stations, low-skilled labor intensity, easy to start, and conducive to the realization of automatic control pump unit.

升降平台射流泵充水法用柴油机带动水泵抽水时，可利用柴油机排除的废气通入与水泵顶部相通的射流器，进行抽气充水，从而去掉了水泵的底阀。在水泵启动时，将和手柄相连的阀盖关闭，废气从射流器喷出，通过连管把泵中的空气吸出。充水完毕后把阀盖打开，控制阀关闭。这种充水方法的好处一是充分利用了动力机，二是提高了泵站的效率。
Wenzhou lifting platform when filled with water jet pump with diesel engine driven pumps pumping method can be used to exclude diesel exhaust through the top and interlinked ejector pump, pumping down water-filled, thereby removing the bottom valve of the pump. When the pump starts, the valve and the handle is connected to the lid closed, the exhaust from the jet ejected through the pipe connecting the pump to suck out the air. Filled with water after the completion of the bonnet is opened, the control valve is closed. The advantage of this method of water-filled one full advantage of the power machine, the second is to improve the efficiency of the pumping station.
