Problems solved by technology
During the operation of the motor, since the skeleton oil seal is a non-forced seal, it cannot completely prevent quicksand from entering the motor
Many manufacturers have installed mechanical seals on the sand throwing part, and the sand control effect is not ideal due to improper installation
The quality of the water medium in the water-invasion submersible motor directly affects the service life of the motor. If quicksand enters the inner cavity of the motor, it will aggravate the wear of the bearings in various parts, and in severe cases, the motor will be scrapped

The invention relates to a sand prevention device of a submerged pump motor. The sand prevention device is characterized in that an independent sealing chamber is composed of a sealing chamber cover (4) and a sealing chamber base (5), a motor shaft (9) penetrates through the center of the sealing chamber, a mechanical seal (3) is arranged in the center of the sealing chamber, a fluctuation sand throwing device (1) is arranged on the sealing chamber cover (4), a framework seal (2) is arranged in the center of the fluctuation sand throwing device (1), and an air exhaust valve (6) is arranged on a motor chamber (10). Under the effect of three protective screens, the 100% sand prevention effect can be achieved; the design of the special air exhaust valve is adopted, quick sand is prevented from entering a motor cavity, it is guaranteed that gas pressure generated when the motor normally works is timely discharged, the technical problem of sand prevention of the water invasion type submerged pump motor is effectively solved, economic benefits of users are improved, and a large number of energy resources are saved.
Description
technical field [0001] The invention relates to the field of submersible pumps, in particular to a sand control device for submersible pump motors. Background technique [0002] The groundwater source is infiltrated from the sandstone formation, and the sandstone composition in the extracted groundwater is unavoidable. Currently. The water lifting facility is composed of water pumps and power equipment. Submersible motor is the power source of water lifting facilities, its design and performance will directly affect people's production and life. The sand control performance of the submersible motors in the prior art cannot be effectively controlled, which is also a technical problem faced by many manufacturers. The working principle process of traditional submersible motor sand control: quicksand—sand shaker—skeleton oil seal, the rotating sand shaker will shake off part of the quicksand through the rotating centrifugal force of the sand shaker, but there will still be so...
