What problems should be noted when using the low pressure test chamber

Date: Oct 19,2022 Views: 227

As the equipment in the process of use will inevitably have problems, there will be low pressure high and low temperature humidity and heat test chamber compressor exhaust volume is insufficient, if encountered low pressure high and low temperature humidity and heat test chamber compressor exhaust volume is insufficient when how to solve it?

 

A, the inlet filter failure.

(1) the accumulation of scale blockage

(2) so that the exhaust volume is reduced

(3) suction tube is too long

(4) the diameter of the pipe is too small, resulting in increased suction resistance affects the volume of gas, to regularly clean the filter.

Second, the compressor speed to reduce the exhaust volume.

(1) improper use of air compressor, because the air compressor exhaust volume is designed according to a certain altitude, suction temperature and humidity

(2) when it is used in more than the above standards on the plateau, suction pressure is reduced, etc., the exhaust volume is bound to reduce.

Third, the cylinder, piston, piston ring wear serious, super poor, so that the relevant gap increases, leakage increases, affecting the exhaust volume.

Fourth, the stuffing box is not strict, resulting in air leakage to reduce the volume of gas.

(1) The reason is first of all, the stuffing box itself does not meet the manufacturing requirements;

(2) Secondly, it may be due to the installation, the piston rod and the center of the stuffing box is not well aligned, resulting in wear, strains and other causes of air leakage;

(3) generally fill the stuffing box with lubricant, it can play the role of lubrication, sealing, cooling.

Fifth, high and low temperature humidity and heat test box compressor suction and exhaust valve failure on the exhaust volume.

Sixth, the gas valve seat and valve piece between the fall into the metal fragments or other debris, resulting in the closure is not tight, the formation of gas leakage.

Seven, the gas valve spring force and gas force is not well matched.

Eight, the compression force of the gas valve is not appropriate. The compression force is small, it is going to leak gas, of course, too tight is not good, it will make the valve cover deformation, damage.
