How to deal with insufficient exhaust of the compressor in the two boxes of cold and thermal shock test chambers

The efficiency of the cold and thermal shock test chamber in the use of the process is very important, if the cold and thermal shock test chamber compressor exhaust is insufficient, it needs Liuqin technology and technical personnel to solve it in time, then, how to solve it better? The filter of the hot and cold shock test chamber is clogged with scale, which reduces
the exhaust volume.

The filter needs to be cleaned in time to solve the problem
.

The suction tube is too long and the diameter of the pipe is too small, resulting in increased suction resistance affecting the air volume; It is necessary to increase the diameter of the suction pipe in time and shorten the length of
the suture pipe.

Because the exhaust volume of the air compressor is designed according to a certain altitude, suction temperature and humidity, how to use it at a high altitude, the suction pressure is reduced, and the exhaust volume will be insufficient
.

Suitable hot and cold shock chamber compressors
need to be replaced in time.

The cylinder, piston, piston ring wear is severe, super-poor, so that the relevant clearance increases, the leakage increases, affecting the exhaust volume
.

If it is normal wear, it is necessary to replace the wearing parts in time, such as piston rings
.

If the installation is inaccurate and the gap is left in a timely manner, it should be corrected
according to the drawings.

The packing letter of the hot and cold shock test chamber is not strict, and the amount of negative gas leakage is reduced
.

The reason for this is first of all the divergent requirements when the filler letter itself is manufactured; Secondly, it may be because during installation, the piston rod and the packing letter are not aligned well, resulting in wear and strain, resulting in air leakage; Generally, lubricating oil is added to the packing letter, which can play a role
in lubrication, sealing and cooling.

Metal fragments or other debris fall between the valve seat and the valve disc of the hot and cold shock test chamber air valve, resulting in lax sealing and the formation of air
leakage.

This not only affects the exhaust volume, but also affects the change of intermediate pressure and temperature, which may be due to the manufacturing quality, such as valve sheet warpage, etc.
, and the second is because the valve seat and valve disc wear are severe and the air leakage is formed
.

The spring force of the gas valve in the hot and cold shock test chamber is not
well matched with the gas force.

If the elasticity is too strong, the valve plate is slow to open, and if the elasticity is too weak, the valve plate is not closed in time, which not only affects the gas volume, but also affects the increase of power, as well as the life
of the valve disc and the spring.

At the same time, it will also affect the change of
gas pressure and temperature.

The pressing force of the hot and cold shock test chamber pressing the air valve is improper
.

The pressing force is small, then it will leak air, of course, too tight is not enough, will make the valve cover deformed, damaged, the valve has a failure, the valve cover fever, and the pressure is not normal
.

These faults of the cold and thermal shock test chamber need to be solved in time after some faults are found, and at the same time, it is usually necessary to pay more attention to maintenance and maintenance to reduce the failure rate of
the cold and thermal shock test chamber.
