What does vacuum sealing oil do? What is the role of the sealing oil system

When there is a problem with the vacuum pump, it can be tested by itself according to the manufacturer's opinion, and if it still cannot be solved, it may need to be repaired in the factory. As a well-known vacuum pump manufacturer, Busch Vacuum can provide a full set of after-sales service, including standardized maintenance, service maintenance contracts, exchange services, etc., and can arrange professional technicians to come to your door to solve problems when the problem is still not solved. If you feel that the above is not detailed enough, you can consult Busch Vacuum Equipment International ** (Shanghai)****.

With more than 50 years of experience in the field of vacuum pumps and vacuum systems, Vacuum Solutions International (Shanghai) and Vacuum Solutions (Shanghai) are wholly owned subsidiaries of Vacuum Solutions in China, and with more than 50 years of experience in the field of vacuum pumps and vacuum systems, Vacuum Solutions offers a wide range of products for a wide range of industrial vacuum products all over the world....

At room temperature and at rest, it is like a solid, able to maintain its shape without flowing, and can adhere to metal without slipping. At high temperatures or when subjected to external forces that exceed a certain limit, it can flow like a liquid. When grease is sheared by moving parts in machinery, it creates flow and lubrication, reducing friction and wear between moving surfaces.

When the shear action stops, it can regain a certain consistency, and this special fluidity of the grease determines that it can be lubricated in parts that are not suitable for lubricating oil. In addition, because it is a semi-solid substance, it seals and protects better than lubricating oil. You can refer to Shenzhen Terunbao lubricating materials **** and so on.

The simplest, castor oil. It is often used for lubrication and sealing of rubber gasket seals.

Others have vacuum greases: such as high vacuum silicone ointment, apisone ointment, ramcha ointment.

If the vacuum level is not high, you can also try petroleum jelly.

For power generation cooled with hydrogen.

In order to prevent hydrogen leakage, the generator is equipped with sealed plate tiles at both ends. The function of the sealing oil system is to supply oil to the sealing pad, and at the same time separate the hydrogen, air and moisture in the oil, and play the role of purifying the oil.

Input of airside sealing oil system: open the airside sealing oil to the throttle, the sealing oil system is filled with oil normally, open the airside sealing oil pump recirculation door, start the airside AC sealing oil pump, and check the normal operation of the oil pump.

Slowly open the airside sealed oil cooler into the throttle, gradually close the recirculation door, pay attention to the main differential pressure valve open and large accordingly, maintain the differential pressure left and right, open the airside DC sealed oil pump, after the test is normal, put it into standby.

Look at the words! Of course, it plays a sealing role.

1. The static sealing mechanism is relatively simple, the sealing interface of the oil seal is a narrow ring belt with a width of to, and under the action of preload, there is generally an average radial contact pressure of about 1N per mm2 between the oil seal and the shaft; When the lubricating oil pressure falls below this pressure value, the oil seal prevents it from leaking to the outside world. However, leaks can still occur when the static non-leaking oil seals are in operation. Tanyou.

2. Dynamic sealing mechanism: In the normal operation process, the oil first enters the narrow belt in contact with the shaft through capillary action and the pumping action of the rough tissue. When there is access to this contact surface, the pumping action comes into play.

The cascaded microscopic pump Hu Xin bench on the atmospheric side has a high potential pumping capacity, and on this basis, a hydrodynamic pressure balance is formed. Now, the seal runs on the oil film and stays tight.
