Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] refer to Figure 1 to Figure 4 It can be seen that a new type of amphibious self-circulating double-cooling submersible sewage pump includes a motor casing 1, a wiring chamber 2, a wiring chamber gland 3, an oil chamber 4, a buffer sealing chamber 5, a pump cover 6 and a pump body 7. A wiring chamber 2 is fixedly installed above the motor casing 1, a wiring chamber gland 3 is fixedly installed above the wiring chamber 2, an oil chamber 4 is installed below the motor casing 1, and a buffer is installed below the oil chamber 4. A sealed chamber 5, a pump cover 6 is installed at the bottom of ...

Abstract

The invention relates to a novel amphibious self-circulation double-cooling submersible sewage pump. The novel amphibious self-circulation double-cooling submersible sewage pump comprises a motor shell, a wiring chamber, a wiring chamber pressing cover, an oil chamber, a buffer sealing chamber, a pump cover and a pump body. The wiring chamber is fixedly formed above the motor shell, the wiring chamber pressing cover is fixedly installed above the wiring chamber, the oil chamber is formed below the motor shell, the buffer sealing chamber is formed below the oil chamber, the pump cover is installed at the bottom of the buffer sealing chamber, the pump body is installed below the pump cover, a cooling sleeve is installed on the outer side of the motor shell, and a shaft is installed in the middle of the inner side of a motor. According to the novel amphibious self-circulation double-cooling submersible sewage pump, the efficiency is remarkably improved, precipitation and blockage are avoided, the problem that an existing submersible sewage pump is prone to being burnt out is fundamentally solved, and the service life is prolonged; and the water pump can be used for diving and dry occasions, the risk that the motor is damaged due to the fact that a pump station is flooded is eliminated, and the water pump can be exposed to a dry place to be used emergently.

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to a novel amphibious self-circulating double-cooling submersible sewage pump. Background technique [0002] The submersible sewage pumps produced by various manufacturers are all water-collecting cooling devices. During a certain period of time, due to water cooling, the cooling channel is blocked, causing the motor to heat up and the coil to burn out. Due to the long-term operation of the submersible sewage pump, it must be shut down and repaired when encountering such problems. If it is only for maintenance, such problems will occur again after working for a certain period of time, resulting in high maintenance frequency and high maintenance costs. [0003] After years of maintenance on the submersible sewage pump, it was found that the coil of the submersible sewage pump motor was heated and burned out. Since the submersible sewage pump has been cooled by pool water for a long ...
