In the invention, when the gear pump works, firstly, hydraulic oil is pumped from an oil tank in a preset hydraulic mechanism into the second oil pipe 11, in the running process of the driving motor 14 and the speed reducer 13, the second rotating shaft 23 at the lower side drives one gear 25 to rotate, due to the meshing action of the two gears 25, the second rotating shaft 23 at the upper side is driven, under the transmission action of the belt 5, the first rotating shaft 4 starts to rotate, the fan-shaped pieces 28 at the outer side of the first rotating shaft 4 coaxially and directionally rotate, so that the sliding rod 22 arranged at one side of the piston 27 between every two sliding rods slides at the square slideway 21, as the small arc slideway 2101, the transition slideway 2102 and the large arc slideway 3 surround a special-shaped slideway, when the sliding rod 22 slides to the transition slideway 2102 on the small arc slideway 2101, as the curvature radius of the transition slideway 2102 is larger than the small arc slideway 2101, the slide rod 22 drives the corresponding piston 27 to move upwards continuously in the direction close to the inner side wall of the filtering shell 19, the hydraulic oil entering the corresponding piston channel from the second oil pipe 11 is continuously extruded until the slide rod 22 moves to the joint of the transition slideway 2102 and the large arc slideway 2103, at this time, the piston 27 is almost attached to the inner side wall of the filtering shell 19, the hydraulic oil passes through the extrusion filtering gap and passes through the filter screen in the filtering cover 17, the hydraulic oil is guided into the cooling device 12 under the action of the first oil pipe 16, meanwhile, the hydraulic oil is slowly pushed up from the piston channel by the piston 27, the piston 27 extrudes the hydraulic oil and pushes filter residues in the whole piston channel against the side wall of the filtering shell 19, and along with the rotation process, the piston 27 drives the filter residues to rotate through the filtering cover 17, so that oil residue separation is realized;
further, after the piston 27 drives the filter residue to pass through the filter housing 17, the filter residue falls into the cleaning housing 3001 due to its own gravity, when the piston 27 passes through the rubber brush 3008, the rubber brush 3008 can scrape the residual filter residue on the outer side wall of the fan-shaped piece 28, meanwhile, through the sliding sleeve 3003 connected with the compression spring 3004, due to the telescopic effect of the compression spring 3004, the hard extrusion of the rubber brush 3008 and the outer side wall of the fan-shaped piece 28 is avoided, so as to cause large abrasion to the side wall of the fan-shaped piece 28, when the whole gear pump continuously works for a period of time, the filter residue in the cleaning housing 3001 is accumulated, the sealing door 6 can be opened, the sliding sleeve 3003 is pressed downwards, so that the rubber brush 3008 loses the extrusion to the fan-shaped piece 28, so as to draw out the cleaning housing 3001 to clean the filter residue therein, when the piston 27 side wall is seriously abraded after continuously works for a period of time, hydraulic oil is not completely squeezed into the filter housing, therefore, the hydraulic oil can fall into the cleaning shell 3001 along with the filter residues, and the worker is prompted to perform corresponding maintenance and overhaul operation on the gear pump;
further, when the hydraulic oil enters the cooling device 12 through the first oil pipe 16, as the hydraulic oil passes through each cooling through pipe 1203, during the rotation of the first rotating shaft 4, the blowing fan 18 blows air against the side wall of the cooling cover 1202, so that the hydraulic oil continuously cools from top to bottom during the flow of the hydraulic oil, and then enters the gear 25 in the oil cavity 102 of the gear pump through the fourth oil pipe 9 (since the hydraulic oil becomes thinner at a high temperature, the hydraulic system pressure decreases, the mechanical transmission efficiency also decreases), through the engagement between the two gears 25, the hydraulic oil is squeezed into the squeezing cavity 31 formed between the two gears 25, and then the hydraulic oil is squeezed out of the oil outlet 10 through the third oil pipe 29 and is communicated with a preset hydraulic mechanism or other executing mechanisms, and finally is communicated with the second oil pipe 11 through the oil tank therein to form a loop, thereby this gear pump can circulate constantly to carry out filtration treatment to hydraulic oil, prevents that the filter residue from directly getting into to avoid constructing into the damage to pump and executor thereof, solved original gear pump direct filtration and can damage the filter screen because of the impact, and the filter residue can block up the filtration mouth, finally influences the output efficiency's of gear pump problem.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
