Q: The unit has to take out a review question and answer questionHow should emergency handling of engine pump sliding bearings cause heating and smoke?Who knows how to answer one of the troubles?,Then ask a question, generally speaking, sliding bearings, heating, smoke, what are the ways to deal with it, there are known to say, I sum up, good answer: Brother, I did 14 years of mechanical maintenance, sliding bearings, heating, smoke, the most urgent treatment: 1. emergency shutdown. The sliding bearing heating smoke indicates that the clearance between the sliding bearing and the shaft is too tight, or that the grease / grease has impurities (metal scraps) and other things, and that it may be that the bearings have reached the service life and damaged. Maintenance may cause damage to the shaft if it is not shut down, so maintenance costs will be higher. 2. disassemble and repair the pump. Check what causes heat, smoke, cooling is a temporary solution, not only the pump will also heat, and may damage the whole pump. For example, check the running of the bearings, whether there is a deep scratch, or whether the shaft is worn, whether there is a foreign body. After confirming the cause, proceed "the right remedy"".

Q: Sliding bearings relative clearance 0.001 what?: The so-called relative clearance, refers to the sliding bearings of the Bush and bushings, nominal size tolerances can be large or small, but the gap between each other can only be 0.001.

Q: What are the consequences of not hammer sliding bearing: For rolling bearings, both the internal friction and sliding friction, in the case of high-speed rotation, such as poor lubrication, there will be wear, heating, burns, until all damage. If the oil viscosity is too low, when the bearing pressure is large, it is easy to cause fracture of lubricating oil film, caused by dry friction and increased wear; the oil viscosity is too large, the frictional resistance will increase the bearing, so that the temperature, stress will affect the flow of oil, it is difficult to form oil film, instead of bearing harmful therefore, the rolling bearing lubricating oil viscosity selection is particularly important.Ball and roller bearing with mechanical oil, in low and normal temperature conditions, the general choice of L - AN22, L - AN32, L - AN46 viscosity grade lubricating oil, lubricating oil, high speed, large diameter bearings can be selected at a low viscosity and a high selection of lubricating oil the viscosity of.

Q: How is the axial clearance of plain bearings large?: The sliding bearing has a barrel type, has several pieces of tile type, the barrel type general outer circle has the taper, adjusts the back cap to complete the gap adjustment, monolithic tile's general to a tile adjustment can eliminate the gap.

Q: What are the conditions for forming sliding bearings and dynamic oil film lubrication?: Conditions for lubrication of hydrodynamic oil film for sliding bearings:1, must have an oil wedge to form a dynamic pressure, to ensure equal access to oil;2, the thrust plate relative motion to form convergent wedge on the pad;3, the viscosity of the oil is right, the amount of oil appropriate.

Q: What are the bearing capacity of the bearings when they are discharged at the end?: In the case of sufficient oil supply, the end discharge of the sliding bearing will reduce heat, play a cooling role, and can improve the load of the sliding bearing.

Q: Why sliding bearings are divided into bearing housings and bushes, and sometimes on the bearing shell with a layer of bearing liner: Under dry friction conditions, we design a pre - formed synovial membrane on the surface of the bearing to ensure that the solid lubricant is transferred to the dual parts in the shortest possible time, and an effective solid lubricant film is formed

Q: Establishment of oil film bearing capacity of dynamic sliding bearing and several conditions to ensure full liquid lubrication: There is only one condition for complete liquid lubrication: the minimum oil film thickness is greater than the sum of the roughness of the shaft and bearing table.

Q: How does a sliding bearing work?: The sliding bearing has the advantages of large load capacity, high rotary accuracy, and the impact resistance of the lubricating film. Therefore, it has been widely used in Engineering

Q: Fan relatively loud, on-line check found that rolling bearings are best not to oil, sliding bearings can be oiled.I was depressed, I do not know what the fan is bearing.. in fact, the whole hardware blind.Which prawns can say that? It's better to compare the pictures above.. ThanksYes, the video card fan is too loud.. Considering changing?..Originally, I had only a heat sink.. Nothing, but the temperature is too high and the recent game fan.Had to buy 30 yuan. Because of the rush to buy.. The size is not found. The quality is so bad.. A small fan, mounted on a radiator.. My other fans don't have any problems.: There is basically no sliding bearing fan. In fact, it is simple to test whether or not to roll bearings: to blow a breath on the fan blades, and then to rebound when they stop, they are all rolling. No matter what type of fan can be oiled, this upstairs brother is quite right.
