Problems solved by technology

This utility model can be used in the oil station system, low pressure pulsation, low noise, no leakage and safe and reliable. The pump inlet is immersed in the oil in a vertical direction, but it has the following disadvantages. When the oil contains impurities, the impurities will enter the screw pump together with the oil. , Long-term use of impurities will accumulate in the screw pump and cause blockage, affecting the delivery of oil

Embodiment

[0040] Anti-clogging pumping devices such as figure 1 and figure 2 As shown, it includes a motor 1, a protective cover 2, a screw pump 3 and a filter mechanism 4 connected in sequence. The filter mechanism 4 is arranged at the inlet end of the screw pump 3, and an output assembly 5 is connected to the outlet end of the screw pump 3. The motor When 1 works, it drives the screw pump 3 to work, and the oil enters the screw pump 3 through the filtration of the filter mechanism 4, and then is delivered to the designated position from the output assembly 5.

[0041] refer to figure 2 and image 3The protective cover 2 is a cylindrical shell with a hollow interior and an open end. An annular fixed plate 21 is connected to the open end of the protective cover 2, and the motor 1 and the fixed plate 21 are fixed by bolts. combine Figure 4 and Figure 5 A shaft hole 22 is provided at the axis of the protective cover 2 away from the open end, a number of perforations 23 are evenly...

Abstract

The invention discloses an anti-blocking pumping device. According to the technical scheme, the anti-blocking pumping device is characterized by comprising a screw pump and a filtering mechanism which is arranged at the inlet end of the screw pump, wherein the screw pump comprises a pump shell and a screw assembly; the filtering mechanism comprises a shell, a support which is fixed into the shell and a filtering assembly which is arranged on the support in a sleeving manner and can rotate relative to the support; through gear transmission, the screw assembly drives the filtering assembly to rotate, the interior of the filtering assembly communicates with the interior of the pump shell, an inlet is formed in the side wall of the shell in the direction of a generatrix, and scraper blades abutting against the filtering assembly are arranged on the two sides of the inlet in the shell. The anti-blocking pumping device solves the problem that an existing screw pump is blocked due to the fact that oil contains impurities.

Description

technical field [0001] The present invention relates to hydraulic equipment, and more particularly, it relates to an anti-clogging type pumping device. Background technique [0002] The screw pump is a displacement rotor pump, which relies on the volume change of the sealed cavity formed by the screw and the bushing to suck and discharge the liquid. Screw pumps are divided into single screw pumps, double, three and five screw pumps according to the number of screws. The characteristics of the screw pump are stable flow, small pressure pulsation, self-priming ability, low noise, high efficiency, long life, and reliable operation; and its outstanding advantages are that no eddy current is formed when conveying the medium, and it is not sensitive to the viscosity of the medium. Conveying high viscosity media. [0003] Due to the mutual engagement of the screws and the tight fit between the screws and the inner wall of the liner, one or more sealed spaces will be separated bet...
