"Q & a series of technical problems of air compressor (five)" refer to: http://www.dg-zhihe.com/cn/newsshow.asp? Id=422

Small make up: air compressor cylinder part of the abnormal vibration is what reason?

History and technology: master cylinder abnormal vibration for several reasons:

1, supporting the poor, should support good.

2, pipeline forced vibration, should strengthen the pipeline support.

3, the cylinder intrusive inclusions or liquid, remove inclusions.

4, the cylinder and the crosshead slide concentricity is not normal, should findconcentricity.

5 cylinder, the location is not good or other connecting parts are loose.

6, valve working condition is not good. Abnormal wear 7, packing, pallet or piston ring,large axial clearance, replace components.

Small make up: the fuselage for air compressor abnormal vibration, what reason is this?

Chi and technology teacher: 1, bearing crosshead skateboards gap is too large,should be adjusted bearing crosshead skateboards clearance or replacement parts.Abnormal vibration, cylinder 2. 3, the Ministry of machinery with bad, should be thoroughly fastening bolt.

Small make up: why sometimes the body part of air compressor will be some abnormalvibration?

Chi and Technology Master: This is probably the following causes: the bearing,crosshead pin and slide clearance is too large, should be adjusted each part clearance. The cylinder should be caused by vibration, clearance or piston rod piston and cylinder cap. Apricot is loose, the cylinder is effusion or any foreign body. Eachcomponent bonding is not good, should check the adjustment. The cylinder and thecrosshead slide not concentric, the piston in the stroke caused by grinding cylinderand vibration, should be carried out to check, adjust the concentricity of the cylinder and slide. With the cylinder suction and exhaust pipeline "don't mind", should be reassembly process.

Small make up: the abnormal vibration of machine pipeline is what reason?

Chi and technology teacher: 1, fixation loosening, should tighten the bolts, preventloosening or replace fastening method. 2, support is insufficient, should be added tosupport. 3, because of the pressure fluctuation caused by resonance, can be inserted into the nozzle to reduce resonance force. 4, pipeline fixing damaged due to expansion, should consider the pipeline thermal expansion direction, re adjust thefixed position. 5, the pipe rack vibration, pipe rack should be strengthened.

Small make up: why air compressor factory we just newly installed base vibration will happen?

Chi and master the technology: iron pad and base, base, not real grievances. The host level for good, should immediately with the welding pad iron welding die, as a whole. Of course, this may also be the air compressor itself too high impact.

Small make up: air compressor temperature causes what?

Chi and Technology Master: roughly one of the following reasons: 1, air compressor room ventilation effect is not good, output compression process of heat accumulation,caused by the environmental temperature is too high or pipeline oil filter blockage,lead to oil supply is not timely. 2, lack of lubrication, resulting in high temperature. 3,the oil is not qualified, can not achieve the desired effect. 4, temperature control valvedamage. 5, long time not clean the radiator, the surface has too much dirtaccumulation, reduce the cooling effect, causing the air compressor temperature.

Small make up: how air compressor temperature? What is a good measure?

Chi and Technology Master: should ensure that the ambient temperature in the requirements of equipment operation range, let the gas can be good cycle; must do regular air compressor maintenance work, ensure efficient operation of each component, the failure rate control at the lowest. The best choice of lubricating oiloriginal, so more conducive to the whole machine working and protection, to avoid excessive wear parts. Damage to valves to control the temperature. Timely repairparts, when there is a problem immediately replaced. In the environment is relatively poor, more impurities in the air condition, increase the number of air compressorcleaning and maintenance.

Small make up: some air compressor user because of the air compressor is installed outdoor production needs, such as coal, so how to do well the lightning protectionmeasures in Dore season?

Chi and Technology Master: the use of screw type air compressor in the mineenvironment the user completes the lightning method is to use the three-phase power lightning box, the box can be used to avoid the lightning through the transmission lineto the screw type air compressor with a lightning strike damage. Three phase power lightning box can be directly connected in series between the air switch and the compressor, together on the demand for the use of reliable grounding, equipmentsimple convenience.

In order to avoid direct lightning outdoor compressor, users can also buried lightning,lightning planning is very simple, is this: a metal pipe is buried underground 1 ~ 2 meters, the other end point and higher than 2 meters above the top of the screwcompressor, screw compressor distance lightning rod within a range of 7 meters. Of particular note is, when there is thunder and lightning, people must not approach ortouch the lightning rod.

Small make up: if the electric screw type air compressor equipment on the outside,then the way of screw type air compressor was struck by lightning damage usually have a what?

Chi and Technology Master: air compressor used outdoors in the thunderstormseason must pay attention to the lightning protection measures, the way to general air compressor damaged by lightning are the following two: 1, the screw type air compressor direct lightning stroke; high voltage into the electrical system of screw compressor transmission line lightning flash 2, formed by the. (of course, the latter is far greater than the former probability attack. So the screw compressor was struck by lightning damage is isolated from the transmission line to avoid the instant highvoltage)

Small make up: in spring, the air compressor which safety problem is to specialattention?

Chi and Technology Master: because the air compressor is electric equipment, is also likely to be struck by lightning (especially in spring thunder season),
