Problems solved by technology

[0002] High-pressure plunger pumps have a wide range of uses and have been widely used in various fields such as industry and life, such as high-pressure cleaners, high-pressure atomization systems, sewer dredging vehicles, hot and cold water cleaners, high-pressure water pumps, high-pressure pumps, carbon dioxide Pumps, high-temperature pumps, etc. At present, plunger pumps on the market use a large amount of various lubricating oils or greases for lubrication. For example, lubricating oil or lubricating oil is required for the up and down movement of the plunger in the pump There are many defects and deficiencies in this kind of pump body that needs to use lubricating oil or grease. The use of lubricating oil will cause a certain degree of pollution to the environment. Sealing measures should be taken for the parts of the pump body that are involved in lubrication. Installation and use bring some inconvenience, at the same time, it is also inconvenient to maintain, and also increases the cost of manufacturing and processing

Embodiment Construction

[0020] The present invention will be further described below with specific embodiment, see Figure 1-7 :

[0021] The environment-friendly high-pressure three-plunger oil-free water pump includes a pump body 110, a pump head 111 and a plunger set. A motor is installed on the pump body 110, and a motor shaft 10 protrudes from the motor. The motor shaft in the pump body 110 is 10 is covered with an eccentric seat 20, the upper end of the eccentric seat 20 is eccentrically arranged on the protruding shaft 21 with a bearing 30, and the bearing 30 is covered with an outer hexagon 40, and the outer hexagon 40 is arranged in the through hole 50 in the middle of the pump body 110. The outer surface of the hexagon 40 is evenly spaced with three spacers 60, and the three plunger holes radially evenly distributed between the spacers 60 and the pump head 111 are sequentially provided with a plunger 70 and a return spring 80, and the inside of the plunger 70 The end is connected with the ...
