Automatic vacuum water filling device for water pumps. Overview of the automatic water filling device for water pumps. The water pump must be filled with water before starting. To achieve automation in a ground-type water pumping station, the key is the automatic water filling of the water pump. For many years, domestic water pump automatic water filling technology has not passed the test. In order to realize the automatic operation of water pumps. Semi-underground self-filling water pumping stations have been built, which not only consumes a lot of construction costs, but also risks the pumps being submerged. The YGSZ water pump automatic water filling device solves the problem of automatic water filling of ground-type water pump stations and lays the foundation for automated operation. Purpose and characteristics of the device This device is used for automatic water filling of water pumps in the water pumping station, so that all water pumps are always in a water-filled state, and any water pump can be started at any time. This device can be used to realize automatic operation of ground-type water pumping stations, and can get rid of the traditional semi-underground self-filling water-filling automatic pumping station design. Therefore, it can save a lot of pumping station construction costs and avoid safe water supply of water pumping stations. The device has good air-tightness, high degree of automation, easy operation, and safe and reliable work. Working principle of the device The device consists of two sets of vacuum equipment (one set is spare), a vacuum box, a circulating water tank, a set of valve fittings and a set of electrical automatic control distribution box. A one-way air valve is installed on the top exhaust port of all water pumps in the pump station and is connected to the vacuum box with a pipeline. The function of the one-way air valve is to allow air that has penetrated into the water pump to freely enter the vacuum box, but water cannot pass through this valve. The vacuum box is equipped with an automatic Activate the signal generator, and the vacuum equipment automatically works according to its instructions. When the vacuum degree in the vacuum box is lower than the lower limit, a start signal is sent to the vacuum equipment to start working. At this time, the vacuum degree in the box rises. When the vacuum degree in the box reaches the upper limit, a stop command is issued. The vacuum equipment automatically stops. In this way, the vacuum degree in the vacuum box is always maintained within a certain range, so that each water pump is always in a water-filled state, and any water pump can be started at any time.
