How to reduce the failure rate in use of high and low temperature thermocells.

how to reduce the failure rate in usehigh and low temperature thermostatHigh and low temperature thermostatic tank using high-precision PID program temperature control, can be directly heated and cooled, can also assist heating and auxiliary refrigeration heat source or cold source, applied to petrochemical, pharmaceutical and other chemical reaction process control, reactor, automatic synthesis instruments, extraction and condensation device thermostat temperature control or external circulation applications, refrigeration system and heating system high-pressure protection and high temperature protection to ensure long-term operation of the instrumentin the practical application of high and low temperature thermostatic tank, in order to effectively guarantee the service life of the equipment, reduce the failure rate in use, as an operator, need to understand some necessary high and low temperature thermostatic tank fault treatment methods, which:1, high and low temperature thermos tank operation high high pressure: high pressure in operation is usually due to: 1) cooling water flow is too little or water temperature is too high, as long as Increase the cooling water flow or reduce the water temperature is good; 2) condenser copper pipe / fin scale, heat exchange effect is poor, when the need to clean the low temperature thermostat heat changer heat exchanger; 3) too much refrigerant, refrigerant too much to discharge part of the refrigerant d expansion valve open to pass small, only need to properly adjust the expansion valve opening2, high and low temperature thermostatic tank running low pressure is too low: low pressure is mainly caused by the following reasons: 1) refrigerant deficiency only need to fill the leak, supplement refrigerant or adjust the expansion valve; 2) filter blockage when the need to clean or replace the filter; 3) expansion valve opening degree dlow temperature thermostat capillary blockage as long as cleaning or replacement capillary3, frozen pump pump water not water: high and low temperature thermostatic tank frozen pump water is mainly due to: 1) pump turn reverse; 2) impeller blockage; 1) correct the pump motor steering; 2) cleaning pump impeller4
, return pipe and compressor shell frosting: high and low temperature thermostatic tank return and compressor shell frosting is mainly caused by three reasons: 1) expansion valve opened too big;.
