Description

Anti-overheating submersible electric pump

Technical Field

The utility model relates to a submerged motor pump technical field especially relates to an anti-overheating submerged motor pump.

Background

The submersible electric pump is a water pump with a pump body and a motor submerged in water, is important equipment for lifting water from a deep well, supplies power to the motor through a cable extending into the well, avoids a transmission long shaft, has the advantages of compact structure, light weight and convenient installation, use and transfer, is mainly applied to aspects of mine emergency, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, fountain landscape and the like, and a suction pipe and a pump are filled with liquid before the submersible electric pump is started. After the pump is started, the impeller rotates at a high speed, the liquid in the impeller rotates along with the blades, the liquid flies away from the impeller and is ejected outwards under the action of centrifugal force, the speed of the ejected liquid in the pump shell diffusion chamber gradually becomes slow, the pressure of the ejected liquid gradually increases, and then the ejected liquid flows out from the pump outlet and the discharge pipe.

Along with the rapid development of pump trade, the structure of submerged motor pump obtains continuous improvement in the production practicality for the performance of submerged motor pump obtains very big promotion, but few producers arouses to attach attention to motor part structure, and submerged motor pump is when the operation, and the motor leads to the fact overheated phenomenon easily when the overload operation under high strength operating condition, leads to the motor to burn out and appears the immersible pump scheduling problem, consequently, we have proposed an anti-overheating submerged motor pump and have solved above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the motor that exists among the prior art and when the overload operation under high strength operating condition, cause overheated phenomenon easily, lead to the motor to burn out the shortcoming that appears the immersible pump shut down, and the overheated submerged motor pump of preventing who provides.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an anti-overheating submersible electric pump, includes the pump body and fixes circulating pump on the outer wall of the pump body, the pump body includes shell body and interior casing, the inside of interior casing is provided with the motor storehouse, install DC motor in the motor storehouse, the winding is fixed with first condenser tube on DC motor's the outer wall, the shell body with be provided with the cooling chamber between the interior casing, and the one end of shell body is provided with the inlet tube to the other end of shell body is provided with the drain pipe, the cooling chamber is located the outside in motor storehouse, and the winding is provided with second condenser tube in the cooling chamber, the one end of second condenser tube with advance water piping connection, and the other end of second condenser tube with water piping connection.

Preferably, install fixed frame on the outer wall of the pump body, the circulating pump is fixed in the fixed frame, and evenly seted up the through-hole on the fixed frame.

Preferably, the output end of the circulating pump is connected with the water inlet pipe.

Preferably, both ends of the first cooling water pipe are communicated with the second cooling water pipe.

The utility model has the advantages that:

when the pump body is used, the device drives external water flow to be conveyed to the first cooling water pipe and the second cooling water pipe through the circulating pump and discharges from the drain pipe, so that the water flow circularly flows in the motor cabin inside the pump body, heat in the motor cabin is taken out, overheating of the motor is reduced, and the service life of the pump body is prolonged.

Drawings

Fig. 1 is the utility model provides a prevent overheated latent water pump's schematic structure.

In the figure: 1 pump body, 2 outer casings, 3 interior casings, 4 motor storehouses, 5 DC motor, 6 first condenser tube, 7 second condenser tube, 8 drain pipes, 9 inlet tubes, 10 fixed frames, 11 circulating pumps, 12 through-holes.

Detailed Description
