Oil pump with anti-blocking function

Abstract

The invention relates to the technical field of oil pumps, in particular to an oil pump with an anti-blocking function. The oil pump main body with the anti-blocking function is characterized by comprising an oil pump body; the surface of the oil pump body is sleeved with a heat conducting device; a filter screen is arranged on the surface of the oil pump body in a sleeving mode and positioned inside the heat conducting device; a supporting device penetrating through the heat conducting device is arranged at the top of the filter screen; a cleaning device capable of rotating in a sliding groove is arranged inside the filter screen; a speed regulating device is arranged at an input end of the cleaning device; a connecting column is arranged between the top of the speed regulating device andthe inner wall of the oil pump body; and two ends of the connecting column are fixedly connected with the speed regulating device and the oil pump main body respectively. By means of the oil pump main body with the anti-blocking function, the use stability and cleanliness of the oil pump are improved, overload work of a motor in the oil pump is reduced, and the service life of the motor is prolonged; and moreover, the filter screen is further cleaned, so that on the one hand, the filter screen is prevented from being blocked, and on the other hand, the service life of the filter screen is prolonged.

Description

technical field [0001] The invention relates to the technical field of oil pumps, in particular to an oil pump with an anti-blocking function. Background technique [0002] The heavy oil pump is suitable for conveying medium temperature not higher than 200℃, viscosity not higher than 1500mm2 / s, heavy oil, diesel oil, coal tar and other low-grade and low-quality combustion oils containing non-metallic impurities. It is especially suitable for fuel injection occasions in petroleum, chemical, grain and oil, building materials, daily chemical, road construction, electric power and asphalt mixing plant departments and industries. It is also more suitable for occasions that require stable working pressure and long-term continuous work, such as: strong lubrication system, etc. [0003] When the heavy oil pump is used to transport crude oil, the following disadvantages are, firstly, the crude oil contains a large amount of solid impurities. When the oil pump is transported, it is f...

Problems solved by technology

[0004] The purpose of the present invention is to provide an oil pump with anti-blocking function, which solves the problem in the prior art that firstly, the petroleum crude oil contains a large amount of solid impurities. It is easy to clog, and it takes a lot of manpower and material resources to clean the filter screen, which wastes labor and material costs. Secondly, when the oil transfer pump is in use, the filter screen is soaked in petroleum crude oil for a long time. Finally, when the oil pump is in use, it transports viscous petroleum crude oil, the transmission power is relatively large, and it generates more heat. Only relying on the relatively static crude oil near the oil pump motor to dissipate heat, the heat dissipation effect is poor, and the oil pump motor The heat dissipation effect is poor, and the service life of the oil pump is low
