Oil immersed type energy-saving submersible pump

Abstract

The invention relates to an oil immersed type energy-saving submersible pump which comprises a shell, a motor and a water wheel are arranged in the shell, the water wheel is arranged on a motor output shaft, a water pump water inlet and a water pump water outlet are formed in the shell, and the shell comprises an inner shell body and an outer shell body. The inner shell body is sleeved with the outer shell body, a shell water outlet channel is formed between the inner shell body and the outer shell body, the motor is arranged in the inner shell body, an oil cavity blocking cover seals the lower end of the inner shell body, the motor output shaft penetrates through the oil cavity blocking cover and extends into the outer shell body, the water wheel is fixed at the lower end of the motor output shaft in the outer shell body, a water wheel water outlet channel is formed in the water wheel, a water inlet guide tray is arranged at the bottom of the water wheel, the water inlet guide tray is fixedly connected with the outer shell body, a water inlet is formed in the middle of the water inlet guide tray, and the water pump water outlet is formed in the upper end of the outer shell body. The length of a water pump shaft is reduced, loss of the shaft is lowered, the overall structure is compact, the size and weight are reduced, electricity and raw materials are saved, and the oil immersed type energy-saving submersible pump is convenient to carry.

Description

technical field [0001] The invention relates to a water delivery device, in particular to an oil-immersed energy-saving submersible pump. Background technique [0002] The current submersible pump generally installs the motor under the water pump, and the water inlet and outlet of the water pump are installed on the upper side. The motor is prone to heat, easy to be damaged for a long time, and has a short service life. The water pump shell is composed of multiple parts. Bolts are fixed, there are many parts, many seams, the structure is complex, relatively heavy, the manufacturing process is cumbersome, and the sealing effect is not good, water is easy to enter the motor, causing the motor to short circuit and burn out. What have is provided with a water outlet at the low end of the water pump, and the water in the water pump has only when reaching the water outlet, and the water can be thrown out, and the water outlet efficiency is low, wasting electric energy.

[0002] The current submersible pump generally installs the motor under the water pump, and the water inlet and outlet of the water pump are installed on the upper side. The motor is prone to heat, easy to be damaged for a long time, and has a short service life. The water pump shell is composed of multiple parts. Bolts are fixed, there are many parts, many seams, the structure is complex, relatively heavy, the manufacturing process is cumbersome, and the sealing effect is not good, water is easy to enter the motor, causing the motor to short circuit and burn out

Some have a water outlet at the lower end of the water pump. The water in the pump can only be thrown out when it reaches the water outlet. The water outlet efficiency is low and the power is wasted.
