What are the guidelines for vacuum pump oil replacement and maintenance 1. Vacuum pump oil replacement steps Preparation : 1. Make sure the vacuum pump is turned off and cooled to room temperature. 2. Prepare new oil and the tools needed for replacement, such as wrenches, containers, etc. Drain the old oil : 1. Remove the vacuum pump from the system and drain the old oil through the oil drain hole. Be sure to drain the oil before it cools down to prevent the oil from solidifying and causing clogging. 2. Place a waste oil collection container at the drain plug and ensure that the vacuum pump is vented to atmospheric pressure. 3. Unscrew the oil drain plug and drain the waste oil. When the oil volume is significantly reduced, briefly start the vacuum pump for a few seconds to drain more residual oil, and then drain again. Flush the vacuum pump : 1. Use 50% paraffin or diesel fuel as a flushing agent and mix it in a ratio of 2 liters. 2. Unscrew the refueling plug, inject the flushing agent, close the air inlet, run the vacuum pump for at least half an hour and then drain the flushing liquid to ensure that the residual oil and impurities in the pipeline and cooler are completely removed. Add new oil : 1. Unscrew the fill plug and fill with new oil to the specified level. The oil level should remain between the minimum and maximum marks. 2. Reinstall the fill plug and tighten, making sure it is leak-proof. Check the oil level and seals : 1. After filling, check whether the oil level is correct and make sure all seals are intact and replace the seals if necessary. 1.

Vacuum Pump Oil Maintenance Guide Check oil quality regularly : 1. Check the color, smell and viscosity of the oil regularly. If the oil becomes black, has an odor, or has a significant change in viscosity, it should be replaced promptly. Proper storage of oil drums : 1. Oil drums should be placed horizontally and stored in a cool, dry place away from direct sunlight and extreme temperatures to prevent the oil from oxidizing and deteriorating. Avoid mixing different types of oils : 1. Do not mix compressor oil with vacuum pump oil, as their chemical properties and viscosities may be different and mixing may cause damage to the pump. Clean the oil port and oil filter regularly : 1. Clean the oil port and filter regularly to prevent impurities from entering the pump, keep the oil path unobstructed, and extend the service life of the pump. 3. Vacuum pump oil replacement cycle General replacement cycle : 1. The replacement period of vacuum pump oil is usually 3 to 6 months, depending on the frequency of use and working conditions. Special situation handling : 1. If the frequency of use is high, or if the pump oil is contaminated or overheated, the replacement cycle should be shortened to ensure that the performance of the pump is not affected. Long-term use recommendations : 1. Regular oil change is an important part of maintaining the stable operation of the vacuum pump. A reasonable oil change cycle should be set according to the specific conditions of use, and the operation process should be strictly followed during the replacement process to ensure that every detail is handled properly to avoid malfunctions. 4. Summary of detailed steps for changing oil Drain the old vacuum pump oil : 1. Cut off the power supply, turn off the vacuum pump, and ensure that the waste oil is discharged within 20 minutes to prevent the oil from solidifying. Flush the vacuum pump : 1. Use appropriate solvents or prepared flushing agents to thoroughly clean the inside of the vacuum pump to avoid residual oil causing pipe blockage or cooler blockage. Fill with new vacuum pump oil : 1. Fill in the appropriate amount of new oil according to the mark, check whether the oil level is within the normal range, and make sure all seals and filters are intact. Maintenance and inspection : Reinstall all parts, check the operation of the pump, and replace the oil mist separator or other related parts if necessary. 4LManufacturer of Vacuum pump oil

Which parameters of vacuum pumps oil directly affect the vacuum degree? The viscosity of vacuum pump oil is one of the key parameters that directly affects the vacuum degree. The following is the relationship between vacuum pump oil viscosity and vacuum degree, as well as an introduction to the viscosity selection principle: Relationship between vacuum pump oil viscosity and vacuum degree Effect of viscosity on vacuum degree: The viscosity of vacuum pump oil directly affects the performance of oil mist separator. Increased viscosity will cause blockage of oil mist separator, increase the difficulty of gas discharge, and thus reduce vacuum degree. The quality of vacuum pump oil depends on viscosity and vacuum degree, and the vacuum degree depends on the value under different temperature conditions. The higher the temperature, the more stable the vacuum degree performance, which is a good oil. Performance of vacuum degree at different temperatures: At higher temperatures, if the vacuum degree can be stable, it means that the oil is suitable. Other types of vacuum pumps: Choose the corresponding oil according to their speed, processing accuracy, ultimate vacuum, etc. Selection range and principles of vacuum pump oil viscosity Pump speed and rotor linear speed: The higher the speed and rotor linear speed, the lower the oil viscosity should be. The machining accuracy of pump components and the gap between friction parts: The higher the machining accuracy or the smaller the friction gap, the lower the viscosity of the selected oil should be. Pump speed and rotor linear speed: The higher the speed and rotor linear speed, the lower the oil viscosity should be. The machining accuracy of pump components and the gap between friction parts: The higher the machining accuracy or the smaller the friction gap, the lower the viscosity of the selected oil should be. High temperature conditions and cooling water circulation: Under high temperature conditions, oil with higher viscosity should be selected; vacuum pumps with cooling water circulation generally use oil with lower viscosity. 1. Recommended vacuum pump oil viscosity range: 1. Piston vacuum pumps (W type) can use ordinary engine oil, with a viscosity grade of V100 or V150. 2. The rotary vane vacuum pump (2X type) uses oils with viscosity grades of V68 and V100. 3. Direct-connected (high-speed) rotary vane vacuum pump (2XZ type) uses oils of viscosity grades V46 and V68. 4. The sliding valve vacuum pump (H type) uses oils with viscosity grades of V68 and V100. 5. Trochoidal vacuum pumps (YZ, YZR) use oils with viscosity grades of V100 and V150. 6. For the lubrication of the gear transmission system of Roots vacuum pump (mechanical booster pump), V32 or V46 vacuum pump oil can be used. 2. Viscosity selection principle The selection of oil viscosity is one of the important factors affecting the performance of vacuum pumps. The viscosity of a liquid is the resistance to the flow of the liquid, or the internal friction of the liquid. The greater the viscosity, the greater the resistance to the movement speed of various components, the higher the temperature rise, and the greater the power loss; if the viscosity is too low, the sealing performance of the pump will deteriorate, causing gas leakage and vacuum deterioration. Therefore, the selection of oil viscosity for various vacuum pumps is extremely important. The principles for selecting oil viscosity are: 1. The higher the pump speed, the lower the viscosity of the oil should be. 2. The greater the linear speed of the pump rotor, the lower the viscosity of the selected oil. 3. The finer the processing accuracy of the pump components or the smaller the gap between the friction parts, the lower the viscosity of the selected oil. 4. When the vacuum pump is used under high temperature conditions, it is better to choose oil with higher viscosity. 5. For vacuum pumps with cooling water circulation, it is generally better to use oil with lower viscosity. A vacuum pump is a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. In layman's terms, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. According to the working principle of vacuum pump, vacuum pump can be basically divided into two types, namely gas capture pump and gas transmission pump.
