Compressor fault reasons and countermeasures
Compressor is used to improve the gas pressure and gas machinery. From the viewpoint of energy, compressor belongs to the power can be prime mover for gas pressure can machines. With the development of science and technology, and the pressure can be applied widely, compressor in the development of national economy, many departments of the key equipment in a necessary one. The compressor works inevitably there will be some faults, or accidents. The fault is refers to the operation of the compressor appear abnormal condition, once excluded compressor can resume normal work, and that the accident is now damage. Both are often associated, if encounter fault not promptly eliminate will cause serious accidents.
Common fault and its reasons and measures
Displacement:
Displacement is designed with the gas compressors compared. From the following several aspects mainly can consider:
1 intake filter clogging the fault displacement, fouling, reduced. Suction pipe diameter, too long, affects the gas suction resistance increases, regular cleaning filter.
2 compressor rotate to reduce emissions, air compressor, air compressor, improper use of displacement is according to certain altitude, temperature, humidity, inspiratory, when it used in the standard of the plateau, inspiratory pressure reducing emissions will reduce, etc.
3 cylinder piston, piston, worn, super, make relevant clearance, leakage, affecting the displacement. When belongs to the normal, need to change in time, such as the piston parts, etc. Belong to not installed correctly, clearance, should not stay in according to the drawing give correct, if no drawings, preferable experience for piston and cylinder, the gap between along the circumference, such as iron, when the piston cylinder diameters of inner-space value for 0.06/100 ~ 0.09/100, For aluminum alloy piston, clearance for gas path diameter 0.12/100 ~ 0.18/100, The piston alloy steel piston desirable smaller values.
4 the stuffing box is lax produce gas leak to reduce. The first reason is the stuffing box when not requirements; make itself, Next is probably due to the installation, piston rod and stuffing box in the center of, wear well, strain caused by leakage, etc. In general the stuffing box, it raises in oil lubrication, sealing, cooling.
5 compressor suction and discharge valve of the fault displacement effect. Seat and valve between fall into the metal fragments or other sundry, closed lax, forming flat. This not only influence, but also affects displacement between the change of temperature and pressure level, Seat and valve slice contact with the leak lax form, one is recommended for manufacturing quality problems, such as the valve slice, the second is due to warp seat and valve slice badly worn and forming flat.
6 air force and gas well matched. Have strong elasticity is slow, elastic valves open valves closed too weak is not seasonable, such not only affects the volume, but also affects the power, and the increase of air valve slice, spring of life. At the same time, also can affect gas pressure and temperature changes.
7 the clamping force air pressure. Compaction force is small, leakage, of course, not too tight, can make the hood deformation and damage, general compaction force under the available: p = k of PI / 4 D2P2, D for valves for maximum diameter, P2 cavity pressure for more than 1, k, generally take 1.5-2.5, while low k = 1.5 ~ 2.0, high k = 1.5-2.5 when. So take K, proved to be good. A fault, the valve bonnet inevitable fever, nor normal pressure.
