    The small high and low temperature circulation device is suitable for electronic electrician, automobile manufacturing, chemical industry, chemical reaction, etc.
    , and has a large temperature control range
    .

    So what needs to be paid attention to in the regular maintenance and cleaning of small high and low temperature circulation devices? 1.
    To ensure reliable operation; to ensure the temperature of the object to be cooled; to reduce the condensing pressure as much as possible; to give full play to the refrigeration efficiency of the refrigeration equipment
    .

    2.
    Check the instrument frequently; check the running status of the machine frequently; listen to the machine for noise; adjust the valve frequently; check the system for leakage and dripping
    .

    3.
    Clean or replace the filter in time; eliminate hidden troubles in time; remove the scale of the condenser in time; eliminate computer faults in time
    .

    4.
    Operators should strictly abide by the delivery system, strengthen their sense of responsibility and cooperate with each other
    .

    Clearly record the production and machine operation, liquid supply, pressure and temperature, and clarify the faults, hidden dangers and matters needing attention in the operation of the equipment
    .

      5.
    Refrigerants are identified on time and shall not be used beyond the inspection period
    .

    Refrigerants must not be placed near heat sources
    .

      6.
    When charging refrigerant to the refrigeration system, do not vibrate, knock, or collide with the refrigerant; do not expose to the sun in summer
    .

    The refrigeration system of small high and low temperature circulation device consists of refrigerant and four major parts, namely compressor, condenser, expansion valve and evaporator
    .

    Among them, the evaporator is a device that delivers cold energy
    .

    The refrigerant absorbs the heat of the object to be cooled in it to achieve refrigeration
    .

    The compressor is the heart and plays the role of inhaling, compressing and transporting the refrigerant vapor
    .

    The condenser is a device that emits heat, and transfers the heat absorbed in the evaporator together with the heat converted by the compressor work to the cooling medium to take away
    .

    The throttle valve acts as a throttling and depressurization for the refrigerant, controls and adjusts the amount of refrigerant liquid flowing into the evaporator at the same time, and divides the system into two parts: the high-pressure side and the low-pressure side
    .

    In the actual refrigeration system, in addition to the above four components, there are often some auxiliary equipment, such as solenoid valves, distributors, dryers, collectors, fusible plugs, pressure controllers and other components, which are to improve the operation.
    Set for economy, reliability and reliability
