Description

Technical Field

[0001] The utility model belongs to the technical field of piston-type filling industrial pumps, and in particular relates to a piston-type filling industrial pump. Background Art

[0002] As the country strengthens its policy on environmental protection, in order to avoid the accumulation of solid waste such as gangue and tailings in mining areas to pollute the environment and collapse of goafs, most companies use filling industrial pumps to transport paste slurry made from solid waste to the goafs underground in mines for filling. Nowadays, mining technology is becoming more and more mature, and the demand for filling industrial pumps is also increasing. The outlet displacement of most filling pumps is not enough to meet the mining speed. The current maximum conveying volume is generally 400 cubic meters per hour, which cannot meet the conveying requirements of larger demand. If two filling industrial pumps are connected in parallel, the cost and floor space will also increase, and the longest stroke of the conveying cylinder and the main oil cylinder is only 3100mm. The number of reversing times per unit time will cause more wear and the service life of the piston will be shorter. As the conveying volume increases, the hydraulic oil pipe oil circuit will also increase, and the valve group will also increase. There will not be enough space to place the valve group and the hydraulic oil pipe oil circuit, and the installation of the equipment will also be a big problem; filling pumps with large conveying volumes require multiple high-power motors to drive the operation. The placement of multiple motors previously had front and rear positions and left and right positions. Coupled with the entire oil pump motor unit, the filling pump will occupy a large area.

[0003] The delivery volume of the existing piston filling industrial pump can no longer meet the growing mining needs. Because the delivery pressure and delivery volume are large, the wear and tear of the vulnerable parts of the equipment is great, so the wear and tear can be reduced by reducing the number of reversing times per unit time; because of the need to meet the filling of large delivery volumes, multiple high-power motors are required to provide power, and there are also numerous oil pipes, oil circuits and valve groups. There is no extra space for the main valve group and radiator. The front-to-back and left-to-right placement of the power unit takes up too much floor space, and the overall cost is also increased.

[0004] Based on the technical problems existing in the above-mentioned piston filling industrial pumps, there is no relevant solution yet; therefore, it is urgent to find an effective solution to solve the above-mentioned problems. Utility Model Content
