A plunger pump is a piece of machinery commonly used in industry, agriculture, aerospace and military, and its lubrication is critical to its performance and longevity. Therefore, the lubrication treatment of the plunger pump will be introduced in detail below. First, understand the basic structure of the plunger pump. Piston pump is mainly composed of motor, pump body, plunger, inlet and outlet valves. The motor drives the pump rotor to rotate through the motor, fuel engine or other power devices to move the plunger in the pump to realize the suction and discharge of liquid. In the lubrication treatment of plunger pumps, lubricant is the key to keep the plunger pump working smoothly, because it can reduce friction and wear between mechanical parts, and reduce noise and vibration. Oil is the representative of lubricant, its quality and usage will directly affect the performance and life of the plunger pump. The plunger pump is usually lubricated by oil, and oil lubrication can be divided into two types: dry type and wet type. Dry lubrication means that the lubricant is directly added to the friction part in the form of powder, granules, wire rope and other substances. Due to the high temperature of the friction part, the lubricating material is melted and coated on the friction surface to play a lubricating role. Wet lubrication refers to adding lubricating oil to the lubricating area through the oil pump, such as the movement, plunger, bearing and other parts, to achieve the purpose of reducing friction and wear. 90-L-075-HF-5-CD-80-S-4-C7-D-03-GBA-35-35-24 90L075HF5CD80S4C7D03GBA353524 90L075-HF-5-NN-60-P-4-S1-D-03-GBA-42-14-24 90L075HF5NN60P4S1D03GBA421424 90-L-075-HF-5-NN-60-P-4-S1-D-03-GBA-42-14-24 90L075HF5NN60P4S1D03GBA421424 90L075-HF-5-NN-60-R-3-C7-D-03-GBA-29-29-24 90L075HF5NN60R3C7D03GBA292924 90-L-075-HF-5-NN-60-R-3-C7-D-03-GBA-29-29-24 90L075HF5NN60R3C7D03GBA292924 90L075-HF-5-NN-60-R-4-S1-D-03-GBA-35-35-24 90L075HF5NN60R4S1D03GBA353524 90-L-075-HF-5-NN-60-R-4-S1-D-03-GBA-35-35-24 90L075HF5NN60R4S1D03GBA353524 90L075-HF-5-NN-60-R-4-T2-D-03-GBA-35-35-20 90L075HF5NN60R4T2D03GBA353520 90-L-075-HF-5-NN-60-R-4-T2-D-03-GBA-35-35-20 90L075HF5NN60R4T2D03GBA353520 90L075-HF-5-NN-60-S-4-S1-D-03-GBA-35-35-24 90L075HF5NN60S4S1D03GBA353524 The oil lubrication treatment of the plunger pump should meet the following points: Choose the right lubricating oil: According to the actual working environment and requirements of the plunger pump, select the corresponding lubricating oil brand, such as ISOVG series lubricating oil. The characteristics of lubricating oil include viscosity, oxidation stability, rust resistance, wear resistance, etc. These characteristics will directly affect the working efficiency and service life of the plunger pump. Maintain the cleanliness of the lubricating oil: During the working process of the plunger pump, the lubricating oil will produce metal debris or other impurities due to friction, so it is necessary to replace the lubricating oil regularly or use a filter to filter impurities to ensure the cleanliness of the lubricating oil. Regular inspection and replacement of lubricating oil is also helpful to detect whether the plunger pump is working normally, and to find and solve problems in time. Maintain lubricity of lubricating oil: The viscosity of lubricating oil is the key to maintaining its lubricity. Therefore, it is necessary to adjust the viscosity of the lubricating oil according to the operating environment and temperature changes of the plunger pump to ensure that it can provide good lubricating effects under different working conditions. Establish a lubrication maintenance system: formulate a lubrication maintenance system, clarify the cycle and methods of lubricating oil replacement, filling, inspection, etc., establish a sound record system, keep abreast of the lubrication situation and maintenance records of the plunger pump, and reasonably allocate lubrication equipment and personnel , to ensure the smooth progress of the lubrication work. In short, in the lubrication treatment of plunger pumps, it is very important to choose and use lubricating oil correctly, maintain the cleanliness and lubricity of lubricating oil, and establish a lubrication maintenance system. Only by doing a good job of lubrication can the normal operation of the plunger pump be guaranteed and the service life extended.
