Vacuum pump oil is: a kind of lubricating oil specially developed for vacuum pumps on vacuum equipment, which is divided into two types: mineral oil and synthetic oil.

1) The window containing oil must be clean, it is strictly forbidden to expose to the sun and open storage, and it should be stored in a dark, dry and ventilated place to prevent the mixing of water and dust.

2) When taking or filling oil, the light rain around the barrel cover must be removed to prevent debris from mixing into the oil and causing wear and tear of the pump.

3) Different grades and varieties of vacuum pump oil can not be mixed, and new and old oil products cannot be mixed.

4) Strictly avoid mixing vacuum oil with other lubricating oils, and do not mix light oils, otherwise it will affect the vacuum performance.

5) The vacuum pump should try to avoid pumping out solvents, water vapor and corrosive gases, etc., and must be checked and changed frequently.

6) When changing the oil, the used oil in the pump body should be drained out, and the pump shaft should be slowly rotated to clean the pump cavity after pouring new oil into it.

Drain the residual oil, repeat the cleaning several times, and replace it with new oil after washing.

7) During the overhaul of the pump, all parts of the pump must be cleaned with solvent or cleaning agent, and the parts must be dried.

9) When mineral oil is exchanged with ester oil or other synthetic oils, the pump should be disassembled for thorough cleaning. Including all parts and components.

It must be impregnated in ester oil to prevent contamination.

10) If the inhalation of chemical gases and solvents affects the vacuum of pump oil pollution, it must be cleaned and changed.

Vacuum pump plus vacuum pump oil. Vacuum pump oil is a kind of lubricating oil specially developed for vacuum pumps on vacuum equipment, divided into mineral oil and synthetic oil, suitable for reciprocating booster pumps, mechanical booster pumps and oil-sealed mechanical vacuum pumps, etc., and can also be used for various diffusion vacuum pumps. It is recommended for vacuum pumps in handicrafts, ceramics, chemistry and other fields.

In recent years, with the sustained and rapid development of China's economy, the downstream application industry related to vacuum pumps has maintained a rapid growth momentum, and at the same time, driven by the continuous expansion of vacuum pump application fields and other factors, China's vacuum pump industry has achieved sustained and stable rapid development.

Working structure and principle of oil seal:

The oil seal of the reciprocating vacuum pump adopts the skeleton oil seal, and its structure is relatively simple, which is generally divided into three parts: the sealing body (butadiene rubber), the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist, cutting edge and sealing lip according to different parts.

Usually the inner diameter of the oil seal in the free state is smaller than the shaft diameter, so that it has a certain "interference".

Therefore, when the oil seal seat and the shaft are sealed, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring produce a certain radial force on the shaft, after a period of operation, with the wear of the shaft and the oil seal lip, the pressure decreases rapidly and even disappears, but due to the compensation of the force of the self-tightening coil spring, the oil seal can also continue to be used.

In vacuum pumps, vacuum pump oil is not only used as a medium to obtain vacuum, but also lubricates, cools and seals mechanical friction points.

Generally, there is a recommended special pump oil on the manual, and that one is the most suitable. If not, please contact the manufacturer. For ordinary mechanical vacuum pumps, the choice of oil is ordinary vacuum pump oil.

There are also some pump oil models that have changed, such as 100 and 1. North,,Beijing. Hua'' sincerity. Hao,,,,, vacuum,,Equipment... Limited. Firm.

It is inevitable that the vacuum pump will wear out during operation, and the wear and tear will be serious, and the performance and service life of the pump will also be affected. Adding a certain amount of oil to the vacuum pump can reduce the appearance of wear.

Vacuum pump oil is a special lubricating oil for vacuum pumps, which is generally divided into two types: mineral oil and synthetic oil. Different types and models of pumps use different oils. Generally speaking, N100 oil is used for 2XZ-2 rotary vane vacuum pump, GS-1 oil is used for high-speed direct rotary vane pump, and N100 oil is used for 2XZ-4 rotary vane vacuum pump; 2XZ-4C vacuum pumps generally use 68 vacuum pump oil.

General vacuum pump needs to add special vacuum pump oil, if the oil is not timely or the market lacks suitable varieties, you can use low-viscosity lubricating oil, hydraulic oil instead, but this is not long-lasting, because different kinds of vacuum pump oil, its physical and chemical properties are different, its chemical composition, viscosity, acid value and various additives (anti-wear agents, preservatives, antioxidants, rust inhibitors) and other main components and indicators directly affect the operation of the parts, so it is necessary to use special vacuum pump oil.

1.Vacuum pumps use vacuum pump oil. 2.

Vacuum pump oil is a type of lubricant specially developed for vacuum pumps on vacuum equipment. It is divided into mineral oil and synthetic oil. Oil vacuum pumps are suitable for reciprocating booster pumps, mechanical booster pumps, oil-sealed mechanical vacuum pumps, etc.

Long-term direct contact with air, resins, chemical raw materials, etc. Resistant to deterioration at high temperatures, this reduces the formation of harmful varnish and oil stains and provides longer oil change intervals. Anti-rust and anti-corrosion:

It can form a very effective anti-corrosion film on the metal surface, which can completely prevent the system corrosion caused by the inhalation of corrosive gases and moisture. It quickly separates the water entrained in the oil to achieve the required vacuum level. It has a low vapor pressure that prevents oil from backing up from the pump chamber into the vacuum system, causing oil backflow.

This ensures sufficient extreme vacuum.

Vacuum pump plus special vacuum pump oil. Notes:

1. The shelf life of the oil used in vacuum equipment can reach three years under sealed conditions;

2. The oil should be stored in a cool and dry place;

3. After the oil drum is opened and used, the remaining oil should be covered with a sealed cap, and the remaining part should be used up as soon as possible, and other powder and liquid impurities should not be mixed;

4. Environmental tools should be kept clean, and should be dried after cleaning with solvents;

5. According to the structural accuracy and use environment of the vacuum pump, the oil products with corresponding precision and quality should be selected.

Summary. Hello dear. OK. The oil pump can pump oil in a vacuum situation.

Hello dear. OK. The oil pump can pump oil in a vacuum situation.

The use of vacuum pump oil and precautions requirements 1: the pump oil in the sealing vacuum pump accessories should have a suitable viscosity, which can make the vacuum pump start quickly at low temperature, the pump oil can have good sealing at high temperature, and the pump oil in the pump has a low temperature rise. It does not contain light volatile components, which reduces the oil return rate of the vacuum pump belt during application.

Requirement 2: Saturated vapor pressureSaturated vapor pressure is one of the key indicators of pump oil. In a closed container at a constant temperature, the pressure when the vapor-liquid phase reaches dynamic equilibrium is called saturated vapor pressure.

The saturated vapor pressure of the oil should be kept as low as possible. At the maximum operating temperature of the pump, the saturated vapor pressure should be low enough and below the limit pressure of the vacuum pump rule. At least kPa should be reached at 60 temperature (due to the temperature rise of 20 years, the saturated vapor pressure is about ** order of magnitude).

Requirement 3: Ultimate full pressure and ultimate partial pressureUltimate full pressure: The sum of the pressure generated by all the material files (gases) of the vacuum pump is measured by a Pirani meter or a thermocouple vacuum gauge.

At present, foreign countries pay attention to the test index of full pressure. Limit partial pressure: The ultimate air partial pressure of the pump measured by a mercury compact vacuum gauge (McTelemeter), the partial pressure of the two-stage rotary vane pump should be 6 10-5kpa

The difference between the ultimate full pressure and the limit partial pressure is requested to be no more than an order of magnitude. The greater the difference between the two, the more volatile components are contained in the pump oil and the worse the properties of the oil. Requirement 4:

Smoothness of pump oil in vacuum pump parts, friction wear of friction surface, fatigue and wear of appearance, corrosion and wear, etc.

Hello for you to inquire, can the oil pump pump oil in vacuum? Hello, according to the question of whether you can inject vacuum oil when the vacuum pump is vacuumed, I have inquired about the vacuum pump and special vacuum pump oil for you on the know. 1. The shelf life of the oil used in vacuum equipment under sealed conditions can reach three years; 2. The stuffy fiber oil should be stored in a cool and dry place; 3. After the oil drum is opened and used, the remaining oil should be covered with a sealed cap, and the remaining part should be used up as soon as possible, and other powder and liquid impurities should not be mixed; 4. The environmental leather burning tool should be kept clean, and should be dried after cleaning with solvent; 5. According to the structural accuracy and use environment of the vacuum pump, the oil products with corresponding precision and quality should be selected.

Hello dear, glad to answer for you. Vacuum pumps often require the use of specific vacuum oils or lubricants to keep them functional, and different vacuum pumps may require different types of oils. Specifically, you can follow the steps below to check and select the right vacuum pump oil:

1.Confirm the type and size of the vacuum pump. Different types and sizes of vacuum pumps require different oils.

2.Confirm the physical and chemical properties of the required oil. Vacuum pump spring oil should have good oxidation resistance, heat resistance, low volatility and stability and other characteristics to ensure the performance and life of the vacuum pump.

3.According to the type of vacuum pump and the working requirements, choose the right oil. Generally, vacuum pump oil can be divided into synthetic oil, mineral oil, and halothane oil, among others.

4.Add oil as directed. Before adding oil, please read the operating instructions of the vacuum pump carefully, and pay attention to the use of clean containers and tools when refueling to ensure that the oil is clean and free of impurities.

It is important to note that using the wrong vacuum pump oil may affect the performance and life of the vacuum pump. Therefore, before adding oil, be sure to read the instructions for use of the vacuum pump carefully and follow the guidance in the instructions.

Vacuum pumps use vacuum pump oil. Finger file.

Vacuum pump oil is: a kind of lubricating oil specially developed for vacuum pumps on vacuum equipment, which is divided into two types: mineral oil and synthetic oil. Vacuum pump oil is suitable for reciprocating booster pumps, mechanical booster pumps and oil-sealed mechanical vacuum pumps, etc., and can also be used for various diffusion vacuum pumps. It is recommended for vacuum pumps in handicrafts, ceramics, chemistry and other fields.

N100 vacuum pump oil for 2XZ2 rotary vane test vacuum pump, oil GS1 for high-speed direct rotary vane pump, N100 vacuum pump oil for 2XZ4 rotary vane vacuum pump, and 2XZ4C vacuum pump generally use domestic 68 vacuum pump oil or German Leybold vacuum pump oil JS77 series. Since it is a special oil for vacuum pumps, vacuum pump oil is very different from general engine oil.

Substitute principles for vacuum pump oils:

1. Try to use the same type of vacuum pump oil or pump oil with similar performance and similar additive types.

2. The viscosity should be equivalent, and the viscosity of the substitute vacuum pump oil should not exceed 25% of the viscosity of the original oil. In general, a slightly more viscous pump oil should be given priority as a substitute.

3. The quality is replaced by high quality, that is, the vacuum pump oil with higher quality is used instead, so that the lubrication of the equipment is more reliable. At the same time, it can also extend the service life, which is also economical. <>
