During the use of the Reitz fan, the motor bearing is often refueled or the transmission bearing housing is refueled. It is necessary to refuel according to the requirements, otherwise it will react and affect the service life of the Reitz fan. The performance is different, and the slippery oil products are single.
During the use of the Reitz fan, the motor bearing is often refueled or the transmission bearing housing is refueled. It is necessary to refuel according to the requirements, otherwise it will react and affect the service life of the Reitz fan. The performance is different, and the slippery oil products are single. Therefore, the user should make a choice according to the bearing type, operating speed, load size and process environment of the Reitz centrifugal fan. The decision principle and the following are important:

Mission load

When selecting a slippery oil product, it should be fully considered. The mission load is the load of the bearing (or friction pair) directly affected by static load and dynamic load. Under the condition of smooth and greasy liquid, the viscosity of the greasy oil is larger, and the bearing capacity is larger. When the boundary is slippery, the viscosity is not sensitive to the improvement of the slippery infection, and the oiliness and extreme pressure resistance are not poor. A slippery oil with good pressure performance; for attacking loads, where it is difficult to form a moving or oil film, it is advisable to use a slippery grease or a solid slippery agent. The individual centrifugal fan bearings are radial bearings.

Rate of action

It is also a consideration of the choice of slippery oil. The relative behavior rate is an important parameter for the bearing (or friction pair) structure. The bearing with low relative movement speed is suitable for the use of the viscous oil with large viscosity to facilitate the formation and maintenance of the oil film. The individual speed of the centrifugal fan is higher, and some of them are above 10000r/min, so it is better to use the greasy oil with less viscosity.

Mission temperature

And the temperature that affects this, the mission temperature is the ambient temperature at which the bearing is mission. If the ambient temperature is low, use a slippery oil with low viscosity and low freezing point; when the ambient temperature is high, use a greasy oil with high viscosity and high flash point; when the bearing is in the ambient temperature When the variation is large, it is also necessary to use a slippery oil with good viscosity and good viscosity and high viscosity index. In short, when selecting a slippery oil product, it is necessary to follow the unevenness of the bearing mission ambient temperature, so that the match is reasonable and the mission is reliable.

Slippery pattern

It should be used with good adhesion, gap-type refueling, slippery or slippery oil. The viscous oil with large viscosity; the centrifugal fan is continuous and forced to be smooth, so it should be used with a relatively low viscosity, good oxidation stability, rust prevention, anti-foaming and slippery performance.

Operation

It should also use the corresponding slippery oil with resistance to the medium. If there is any shortening medium, it has special requirements for the greasy oil. In addition, when selecting oil, you should also refer to the creamy oil recommended by the equipment builder.

When choosing a slippery oil product, take a look at the above. First, we must consider the mission and environmental conditions of the equipment to meet the needs of the operation of the equipment; the second is to increase the type of slippery oil products as much as possible to facilitate the management of the lubricants.
