Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, and specifically to a long-shaft deep well pump with a shockproof function. Background Art

[0002] Traditional deep well pumps are prone to vibration during use due to the lack of effective shock absorption measures, which affects the service life and working efficiency of the pump. As a commonly used water pump, the long-axis deep well pump works by driving the impeller to rotate through an electric motor to pump water to the ground. However, due to the long distance between the impeller and the motor, it is easy to vibrate during operation, which reduces the working efficiency of the water pump and causes damage.

[0003] The existing long-shaft deep well pump with anti-vibration function can only cope with the vibration of the pump body in the vertical direction, and lacks the shock-absorbing effect on the lateral vibration. Utility Model Content

[0006] The pump body comprises a shell, a motor is arranged on the top of the shell, a water outlet is arranged on the side, and a water pipe is arranged on the bottom. An impeller and a water inlet are arranged at the lower part of the water pipe. The output shaft of the motor passes through the shell and is connected to the impeller through the water pipe. A clamp is arranged at the bottom of the shell.

[0007] The shock absorbing assembly includes an upper pressure plate, a lower pressure plate and a damping shock absorber. A sleeve is provided in the middle position of the lower pressure plate, and the water pipe passes through the center position of the sleeve. The upper pressure plate is arranged at the upper part of the card plate, and the lower pressure plate is arranged at the lower part of the card plate. The top of the sleeve is arranged on the bottom of the card plate, and the top and bottom of the damping shock absorber are fixedly connected to the upper pressure plate and the lower pressure plate respectively.

[0008] As an improvement, there are multiple damping shock absorbers, which are evenly arranged on the outside of the sleeve.

[0009] As an improvement, polytetrafluoroethylene pads are provided at the center and top of the sleeve.

[0010] As an improvement, a bearing for stabilizing the output shaft is provided in the middle section of the water delivery pipe.

[0011] As an improvement, the impeller is arranged in multiple stages.

[0012] As an improvement, a filter cover is provided on the water inlet.

[0013] The advantages of the utility model are:

[0014] The utility model has a sleeve on the lower pressure plate, and a polytetrafluoroethylene pad is provided inside and on the upper part of the sleeve, which can fix the output pipe and the pump body to prevent them from lateral vibration. At the same time, the utility model has a damping shock absorber between the upper pressure plate and the lower pressure plate, which can effectively resist the longitudinal vibration of the pump body.

[0015] The utility model has good shock-absorbing effects in both the transverse and longitudinal directions of the pump body, can effectively improve the shock-absorbing performance of the pump body, increase the service life of the deep well pump, and avoid damage during operation.
