    In order to ensure that the high and low temperature test chamber better serves everyone, then there are some operations that need to be avoided in the process of using the high and low temperature test chamber, so what do these operations mainly include? Take you to know about it
    .

    First, the high and low temperature test chamber does not start after starting Answer: 1, whether the power supply voltage is within the scope specified in the instructions, the general requirement is 380V, if it is not within the range, it should be equipped with a voltage regulator or find a professional electrician to solve
    .

    2.
    The ambient temperature of the high and low temperature test chamber should not be lower than 5 degrees, otherwise the compressor will not start
    .

    3.
    The low temperature compensation switch is not opened, the low temperature compensation switch fails, and the low temperature compensation heating line cannot be connected
    .

    Answer: The trouble of opening the door mostly occurs in the summer or rainy season
    .

    This is because there are irregular holes
    in the contact surface of the door and the door cover.

    Moist air enters the small holes and forms condensation
    .

    When the door is closed, condensate discharges the air in the hole and forms a negative pressure
    .

    In addition, the magnetic force of the door seal and the contamination of the relay can cause mixing
    .

    Attractive, so when you open the door, it feels hard
    .

    The elimination method is to regularly clean the door seal with soapy water, maintain good elasticity and smoothness, eliminate condensation, and apply a little * stone powder to eliminate
    .

    Third, noise Answer: 1, too much refrigeration oil into the evaporator, will produce a "grunting" bubble sound
    .

    2.
    The fixing screw or nut of the compressor condenser is loose, the water plate is loose, etc
    .

    3.
    Pipeline vibration Due to the long-term suspension of the pipeline, it is easy to have the phenomenon of co-seismic, and the noise increases significantly and presents periodic fluctuations
    .

    When pressed into each vibration-prone part, when pressed into a certain part, the noise is significantly reduced or eliminated
    .

    According to different situations, reinforcement, buffering, isolation and other measures can be taken, such as vibration damping mortar, rubber sleeve, etc
    .

    4.
    Due to the cylinder falling off, the compressor spring is loose, the internal parts are seriously worn, and the lubrication is poor
    .

    The capillary outlet is not smooth
    .

    Since there is no special capillary clip, the outlet cannot be at an angle
    of 45 degrees Celsius.

    5.
    Poor vacuum evacuation, resulting in "grunting" sound, which is manifested as uneven
    temperature of the condenser.
