Description
Technical Field
The utility model relates to a submersible pump, in particular to a high-lift submersible pump device with a high-sealing coupling interface.
Background
The high-lift submersible pump is widely used in water supply, water delivery and other occasions. When the submersible pump works, the sealing leakage-proof water seal coupling installation mode is mainly realized by pressing a coupling interface at the outlet of the pump and a torque generated by the dead weight of a fixed coupling base in a pump pit. The installation mode has defects for the application of the high-lift pump, mainly the high-lift pump works because the direction of the water outlet pressure is forward along the outlet direction of the pump body, the generated reaction torque is opposite to the water outlet direction, when the reaction torque value is larger than the pump weight torque, a gap is formed on the coupling surface from bottom to top, water is sprayed out from the gap, namely, the base and the connector of the automatic coupling device are difficult to seal, the water leakage phenomenon is serious, and the normal use of the water pump is influenced.
Disclosure of Invention
The high-lift submersible pump device with the high-sealing coupling interface is simple in structure and good in coupling surface sealing effect.
The technical scheme adopted by the utility model is as follows: the utility model provides a high-lift immersible pump device of high sealed coupling interface, includes submersible sewage pump, coupling base, its characterized in that: the utility model discloses a submersible sewage pump, including coupling base return bend, coupling base return bend inlet flange end, the sealing washer of compressing tightly between outlet flange end and the coupling base return bend inlet flange end of submersible sewage pump, the sealing washer is including the terminal surface section, pipeline section and the lip section that connect gradually, and terminal surface section crimping is between coupling plate and submersible sewage pump outlet flange end, pore wall in the coupling plate of pipeline section laminating, or by the coupling plate hole laminating to the interior pore wall of coupling base return bend import, the end design of lip section is the bulb form, sets up on the interior pore wall of coupling base return bend import in the identical round recess of bulb cambered surface form shape.
The sealing ring is composed of fiber strands and butadiene-acrylonitrile rubber outside the fiber strands.
The inlet of the coupling base elbow is provided with a groove, and a circle of groove is arranged on the innermost end of the groove or the inner hole wall behind the groove.
The utility model adopts a sealing ring formed by an end face section, a pipe section and a lip section which are connected in sequence, and combines a coupling plate to connect an outlet flange end of a submersible sewage pump and an inlet flange end of a coupling base elbow in a sealing way, the end face section acts on the coupling plate and seals the end face of the outlet flange face of the submersible sewage pump, the pipe section is attached to the inner hole wall of the coupling plate and is tightly sealed under high-pressure water impact pressure, and the lip section expands outwards under the high-pressure water impact pressure to enable a ball head-shaped structure at the tail end of a display mouth to be matched with a groove on the inner hole wall of the inlet of the coupling base elbow and is tightly sealed under pressure, so that a coupling gap between the submersible sewage pump and the coupling base is effectively sealed, the sealing performance is higher, and the lip section is reset when not subjected to the high-pressure water impact pressure.
