Description

Technical Field

[0001] This utility model relates to the field of emulsion pumps, and in particular to an emulsion pump lubrication system. Background Technology

[0002] Emulsion pumps are the hydraulic power source for support equipment in large-scale coal mine fully mechanized mining faces. Their stability and reliability are directly related to the economic benefits of coal enterprises.

[0003] The reliability of lubrication in emulsion pumps affects their performance. Emulsions require lubricating oil supply to locations such as bearings, connecting rods, and sliders. Lubricating oil provides lubrication and heat dissipation to these locations, and reliable lubrication supply to these locations is crucial for the continuous and stable operation of the emulsion pump.

[0004] Patent No. ZL202310284836.8 discloses a forced lubrication and cooling system for an emulsion pump, which can achieve cooling and circulation of lubricating oil. However, during lubrication, it directly sets multiple lubrication pipelines at the lubricating oil tank to achieve oil supply and lubrication separately, and the pipeline layout is too complicated. In addition, existing emulsion pumps mostly use single-sided oil supply, and insufficient lubricating oil supply often occurs at bearings, connecting rods, sliders and other positions, which affects the lubrication effect of the emulsion pump. It is necessary to improve it. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing an emulsion pump lubrication system with a simple structure and improved lubrication effect.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An emulsion pump lubrication system includes a lubricating oil tank, which is connected to a lubricating oil passage disposed within the emulsion pump via a lubrication pipeline assembly. The lubrication pipeline assembly includes a main oil passage pipe, an oil distribution pipe, a lubricating oil distribution valve, a gear shaft oil passage connecting pipe, a crankshaft bearing oil passage connecting pipe, a connecting rod oil passage connecting pipe, and a slider oil passage connecting pipe. One end of the main oil passage pipe is connected to the lubricating oil tank, and the other end is connected to the lubricating oil distribution valve via the oil distribution pipe. The lubricating oil distribution valve has four distribution ports on its outer peripheral sidewall, which are respectively connected to the gear shaft oil passage connecting pipe, the crankshaft bearing oil passage connecting pipe, the connecting rod oil passage connecting pipe, and the slider oil passage connecting pipe via the four distribution ports.

[0007] Furthermore, one end of the gear shaft oil circuit connecting pipe is connected to the distribution interface on the lubricating oil distribution valve, and the other end of the gear shaft oil circuit connecting pipe is connected to the gear shaft bearing lubricating oil passage in the emulsion pump and supplies lubricating oil to several gear shaft bearings in the emulsion pump.

[0008] Furthermore, one end of the crankshaft bearing oil circuit connecting pipe is connected to the distribution interface on the lubricating oil distribution valve, and the other end of the crankshaft bearing oil circuit connecting pipe is connected to the crankshaft bearing lubricating oil passage provided in the emulsion pump, and supplies lubricating oil to several crankshaft bearings provided in the emulsion pump.

[0009] Furthermore, one end of the connecting rod oil circuit connecting pipe is connected to the distribution interface on the lubricating oil distribution valve, and the other end of the connecting rod oil circuit connecting pipe is connected to the connecting rod lubricating oil passage in the emulsion pump and supplies lubricating oil to several connecting rods in the emulsion pump.

[0010] Furthermore, one end of the slider oil circuit connecting pipe is connected to the distribution interface on the lubricating oil distribution valve, and the other end of the slider oil circuit connecting pipe is connected to the slider lubricating oil passage in the emulsion pump and supplies lubricating oil to several sliders in the emulsion pump.

[0011] Furthermore, two lubricating oil distribution valves are provided. One end of the main oil circuit pipe is connected to the middle of the oil circuit branch pipe, and both ends of the oil circuit branch pipe are connected to the two lubricating oil distribution valves respectively. The two lubricating oil distribution valves are symmetrically arranged on both sides of the emulsion pump. The gear shaft oil circuit connecting pipes on the two lubricating oil distribution valves are respectively connected to both ends of the gear shaft bearing lubricating oil passage. The crankshaft bearing oil circuit connecting pipes on the two lubricating oil distribution valves are respectively connected to both ends of the crankshaft bearing lubricating oil passage. The connecting rod oil circuit connecting pipes on the two lubricating oil distribution valves are respectively connected to both ends of the connecting rod lubricating oil passage. The slider oil circuit connecting pipes on the two lubricating oil distribution valves are respectively connected to both ends of the slider lubricating oil passage.

[0012] Furthermore, the emulsion pump is equipped with a return oil passage, which is connected to the middle of the gear shaft bearing lubrication passage, crankshaft bearing lubrication passage, connecting rod lubrication passage, and slider lubrication passage, respectively. The return oil passage is connected to the lubricating oil tank through a return oil pipe.

[0013] Furthermore, the main oil line is sequentially equipped with a lubricating oil pump for pumping lubricating oil, a filter for filtering impurities from the pumped lubricating oil, and a radiator for cooling the pumped lubricating oil. The lubricating oil in the lubricating oil tank passes through the lubricating oil pump, the filter, and the radiator in sequence before entering the oil line branch pipe.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are: In this invention, during the lubrication operation of the emulsion pump, the lubricating oil in the lubricating oil tank enters the oil distribution pipe through the main oil line, and then flows into the gear shaft oil line connection pipe, crankshaft bearing oil line connection pipe, connecting rod oil line connection pipe, and slider oil line connection pipe respectively after entering the lubricating oil distribution valve. This ultimately achieves the oil supply operation to the gear shaft bearing lubrication passages, crankshaft bearing lubrication passages, connecting rod lubrication passages, and slider lubrication passages within the emulsion pump. The oil distribution is achieved through the lubricating oil distribution valve, eliminating the need for excessive piping between the lubricating oil tank and the emulsion pump, thus simplifying the arrangement of lubrication piping. It is more concise; furthermore, this utility model uses two lubricating oil distribution valves on both sides of the emulsion pump to simultaneously supply oil to the gear shaft bearing lubrication passage, crankshaft bearing lubrication passage, connecting rod lubrication passage, and slider lubrication passage, ensuring sufficient lubrication oil supply to the bearings, connecting rods, sliders, and other parts within the emulsion pump; at the same time, if one oil supply line is blocked or malfunctions, the other oil supply line will still ensure the normal operation of the emulsion pump lubrication, without significantly affecting the lubrication effect of the emulsion pump, further improving the effectiveness of this utility model.
