Problems solved by technology
Since the deep well pump is vertically erected underground, most of the deep well pumps now pump water into the pump through the filter screen and then pump it up from the middle of the impeller. In this way, due to the gravity of the water itself, part of the water It will not be pumped up and fall back into the water source, resulting in leakage. At the same time, when the original deep well pump is used at low head, the power is easily overloaded and the motor is burned

The invention provides a full lift deep well pump, which belongs to the technical field of water pumps. It solves the problem that the existing deep well pump has large leakage and is only suitable for high head. The full-lift deep well pump includes a cylindrical pump body and a motor with a motor shaft installed in the pump body. One end of the pump body is provided with a water outlet seat with a water outlet, and a ring-shaped filter is fixed between the water outlet seat and the pump body. , the upper bearing seat and the connecting seat are installed in sequence on the motor shaft, the lower end of the connecting seat is fixedly connected with the upper bearing seat, and the upper end is fixedly connected with the water outlet seat through screws. The upper end of the connecting seat has a circular groove and is opened on the outer surface of the groove The water inlet part communicates with the inside of the groove. The impeller made of copper material is installed in the groove and the impeller is axially fixed on the motor shaft. The water outlet of the water outlet and the water outlet. The full-lift deep well pump has the advantages of compact structure, small leakage, and is suitable for full-lift.
Description
Technical field [0001] The invention belongs to the technical field of water pumps, and relates to a deep well pump, particularly a deep well pump suitable for full lift. Background technique [0002] Deep well pumps are mainly used to drain wells and sink into boreholes for drainage. The biggest feature of the deep well pump is the integration of the motor and the pump. It is a pump that is immersed in water to suck and transport water. It is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. [0003] The existing deep-well pump generally consists of a cylindrical pump body and a motor with a motor shaft installed in the pump body. One end of the pump body is sealed and fixedly connected with a gland, and the other end is provided with a water outlet seat with a water outlet. A ring-shaped filter screen is fixedly connected between the base and the pump body, and an upper bearing base and a co...
