Air conditioner bearings pay attention to the following points:
From the perspective of use, to ensure that the bearing can work reliably, pay attention to the following points:
1. Improve the quality of lubrication, control the pressure, temperature and flow of oil, and strengthen oil filtration.
2. Use fuel and lubricating oil that meet the regulations.
3. It is unfavorable to control the temperature state of the diesel generator set, and it is unfavorable to work under the condition of supercooling and overheating. In cold weather, the diesel engine should be preheated before starting, and the crankshaft should be turned by hand to allow the oil to enter the friction surface.
4. The surface quality and geometry of bearings and journals should be strictly guaranteed.
5. The bearing clearance should be appropriate. If the generator set is too large, it will cause shock. If it is too small, the lubrication will be poor and the tiles may burn.
Air conditioner bearing maintenance:
It is also important to design and manufacture disassembly tools as needed. When dismantling, study the dismantling method, sequence,
Investigate the matching conditions of the bearing to obtain insurance for the disassembly operation.
Removal of the outer ring To remove the outer ring with interference fit, set several screws for the outer ring extrusion screw on the circumference of the outer casing in advance, and tighten the screw evenly while disassembling. These screw holes are usually covered with blind plugs, separable bearings such as tapered roller bearings, and several notches are set on the shoulders of the housing. Use spacers to remove them with a press, or gently tap to remove. The disassembly of the inner ring can be easily pulled out with a press. At this time, pay attention to let the inner ring bear its pulling force.
Furthermore, the pull-out clamps shown are mostly used, and no matter which kind of clamps, they must be firmly clamped on the side of the inner ring. For this reason, it is necessary to consider the size of the shaft shoulder, or study the machining of the upper groove at the shoulder, so as to use the drawing jig. The disassembly of the inner ring of the large bearing adopts the hydraulic method. Oil pressure is applied through the oil hole provided in the bearing to make it easy to pull out. For bearings with large widths, the hydraulic method is used in combination with the pulling jig for disassembly. The inner ring disassembly of cylindrical roller bearings can use the induction heating method. A method of drawing by heating the part in a short time to expand the inner ring. Where a large number of these bearing inner rings need to be installed, the induction heating method is also used.
Car air conditioner bearing is broken
If the bearing of the empty blower is damaged, abnormal noise will be heard in the glove box when the empty blower is turned on. If the bearing is damaged, the bearing can be replaced directly, or the entire fan can be replaced directly. The blower is an important part of the automobile air conditioning system. If there is no blower, the air conditioner outlet will not blow air.
The empty switch is an important comfort configuration in the car. The car air switch can be used for cooling or heating.
When the car air conditioner is cooling, the compressor clutch will be engaged, and the engine will drive the compressor to run.
When the compressor is running, it can continuously compress the refrigerant and transport it to the evaporating box, where the refrigerant continuously expands and absorbs heat, thereby cooling the evaporating box.
Cooling the evaporative box can cool the air blown by the blower, so that the empty air outlet of the car blows cold air.
When the car air conditioner heats up, the high-temperature coolant in the engine will flow through the warm water tank, and the wind from the blower will also pass through the warm water tank, so that the air outlet of the car can be adjusted to blow warm air.
The refrigerant used in the car air is r134a, and the car air needs to be regularly added with refrigerant.
Otherwise, the cooling speed of the car will be slowed down and the cooling effect will be worse.
It is recommended that you regularly add refrigerant and clean the air conditioning system when using the car, otherwise a lot of bacteria will grow in the air conditioning system.
Dear Sirs, my name is Oswaldo Moreno, Im from Venezuela and im interested to buy one of these bearings for my Dodge Caliber's Gearbox, Id like you to contactme through my email.
