Problems solved by technology
However, the transmission mechanism of the existing plunger pump is all lubricated by the lubricating oil in the crankcase; The seals are prone to oil leakage. Once the oil leakage reduces the oil level in the crankcase to a certain extent, it will also burn the crankshaft, connecting rod and plunger.

The invention relates to a lubrication device of a plunger pump transmission mechanism. In the technical scheme, the lubrication device comprises a crankcase, a crankshaft is arranged in the crankcase and is driven by power, a crankshaft bearing is arranged in the matching position of the crankshaft and the crankcase, the crankshaft drives a connecting rod, the connecting rod drives a plunger through a plunger pin, and the plunger is matched with a plunger hole in the crankcase. The lubrication device is characterized in that the crankshaft bearing is a bearing completely sealed by high-temperature lubricating grease, a needle bearing is arranged in the large head of the connecting rod, the inner hole of the needle bearing is matched with the crankshaft, high-temperature lubricating grease is coated in the needle bearing, an oil-containing slide bearing is embedded in the small head of the connecting rod, the inner wall of the oil-containing slide bearing is matched with the plunger pin, a wear-resistant and high-temperature-resistant plunger sleeve is arranged in the plunger hole of the crankcase, and the inner wall of the plunger sleeve is matched with the plunger.
Description
technical field [0001] The invention relates to a plunger pump, in particular to a lubricating device for a plunger pump transmission mechanism. Background technique [0002] Piston pumps are widely used in agricultural machinery and plant protection machinery, such as water conservancy irrigation, agricultural and forestry spraying, weeding, and insecticide; orchard water supply and drainage, pest control; greenhouse, farm cooling, humidification, and industrial cleaning. field. However, the transmission mechanism of the existing plunger pump is all lubricated by the lubricating oil in the crankcase; The seals are prone to oil leakage. Once the oil leakage reduces the oil level in the crankcase to a certain extent, the crankshaft, connecting rod and plunger will also be burned. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a lubricating device for a plunger pump transmission mechanism...
