Problems solved by technology

However, submersible motors operate underwater, and sometimes the operating depth is relatively large, and the underwater pressure acts on the motor, which is likely to cause damage to the motor and affect the service life of the motor. Frequent replacement of the motor affects the progress of the process, which is not conducive to underwater operations.

Abstract

The invention provides a novel submersible motor dual-leather-cup adjusting device. The novel submersible motor dual-leather-cup adjusting device is fixed in a cavity of a motor base, the motor base is provided with reinforcing ribs, the adjusting device comprises an upper leather cup and a lower leather cup, the upper leather cup is of a convex arc-shaped structure, the lower leather cup is of aconcave arc-shaped structure, a closed buffer cavity is formed between the upper leather cup and the lower leather cup, and the adjusting device is fixed on the base by means of the reinforcing ribs.The novel submersible motor dual-leather-cup adjusting device has the advantages and positive effects of being capable of adjusting a pressure difference between inside and outside continuously when the pressure difference between inside and outside is large, so that the pressure difference between inside and outside tends to be balanced, thereby protecting a motor against damage.

Description

technical field [0001] The invention relates to the technical field of submersible motors, in particular to a motor double leather cup adjustment structure. Background technique [0002] The submersible motor is used in combination with the pump, or the shaft end of the submersible motor is directly mounted on the pump parts to form a product that combines the pump with the machine. Dive into underground water or work in rivers, lakes, ocean water and other occasions. It has the advantages of small size, light weight, no need for water diversion before starting, no limitation of suction, no need for another pump room, convenient installation and use, reliable performance, high efficiency, low price, and investment saving, etc. Water intake from underground mines or rivers and lakes, agricultural irrigation, urban water supply, drainage of industrial and mining enterprises, drainage of urban and rural buildings, domestic water for residents, urban or factory sewage and sewag...
