The high and low temperature test box is a very common inspection and experimental equipment, but the equipment will emit a certain noise during the whole process of the operation of the inspection experiment, and this noise will cause some confusion to the surrounding environment, and the whole process of the high and low temperature test box will cause The noise is mainly caused by the motor, centrifugal fan, vibration and other aspects, and it may also be caused by common faults inside the equipment.
Below are some suggestions for controlling noise: 1.
It should be placed in a flat and solid area on the road, and it should be balanced and high on the floor plan.
The four corners of the bottom end of the low temperature test chamber
.
It is also necessary to strengthen the structure of the tube box, and check whether the connection between the outer tube and the high and low temperature test box is loose to prevent the refrigeration compressor from shaking
.
Therefore, the inner and outer wires must be fixed, and the anchor bolts must be fitted with elastic yellow gaskets to prevent loosening
.
2.
The base of the refrigeration compressor should be firmly installed.
If the refrigeration compressor is firmly clamped, the noise will be significantly reduced, and the noise will increase if you release your hand.
This kind of situation is generally because the base of the refrigeration compressor is fixed and the vibration damping rubber is not fixed.
The plate bears uneven force or the anchor bolts are loose, and the bottom plate of the refrigeration compressor is not strong.
It is necessary to adjust and tighten the screw connection and remove and replace the spring washer
.
3.
Place soundproof cardboard along the wall of the machine and equipment
.
Adhere sound-absorbing material such as glass wool board to the board, and then nail the board to the wall behind the high and low temperature alternating test box (refrigeration compressor side).
The cardboard is 10 cm-20 cm larger than the back of the high and low temperature test box
.
4.
Check whether the refrigeration compressor has common faults
.
When the top of the refrigeration compressor is pressed lightly, the noise still does not decrease.
This is generally caused by the excessive gap between the piston rod and the cylinder in the refrigeration compressor.
At this time, the refrigeration compressor should be replaced
.
In addition, when the high and low temperature alternation tester is not turned on, it is about 3 meters away from the test box, and the distance between the tank mouth or "gasp" is obviously heard.
It is a common failure of the refrigeration pipeline and should be repaired by technical professional staff
