Abstract

The invention relates to a submersible pump with a retarder, which is composed of a motor, a pump body, a water pump guide blade body and a pump shaft. The water pump guide blade body is arranged inside the pump body, the pump shaft is arranged on a clapboard positioned in the water pump guide blade body via a bearing, an oil cavity is arranged at the upper part of the clapboard in the water pump guide blade body, a reducciton gear box is arranged at the upper part of the water pump guide blade body, the motor is arranged at the upper part of the reduction gear box, an output shaft of the motor is arranged in the reduction gear box via the bearing, and a reduction mechanism is arranged in the reduction gear box. By arranging the reduction mechanism between the motor and the pump shaft, the invention lowers the number of poles of the motor in the condition of guaranteeing the rotation speed of the pump shaft, and reduces the size and the cost of the motor. With compact structure and low cost, the invention guarantees that the purposes of reducing cost and enhancing effect can be achieved when the water pump is in normal operation, and has outstanding performance.

Description

Technical field: [0001] The invention relates to the mechanical field, in particular to a pump, in particular to a submersible electric pump with a speed reducer. Background technique: [0002] Axial flow pumps, or mixed flow pumps, have the characteristics of large flow and are suitable for medium and low head applications, and are widely used in flood control and drainage, farmland irrigation, water conservancy construction and other fields. The submersible axial flow pump, or mixed flow pump, is increasingly favored by users because of its compact structure, convenient installation and maintenance, and small investment in pump stations. It is an updated product of the traditional axial flow pump unit. In the prior art, the submersible axial flow pump is composed of a motor, a pump body, a pump guide vane body and a pump shaft, the water pump guide vane body is arranged inside the pump body, and the pump shaft is arranged on the pump shaft through a bearing. The partition...
