High and Low Temperature Dampening Tester reliability test

High and Low Temperature Dampening Tester instrument inhibition the whole body is divided into the upper, middle and lower three areas respectively, test area, high low temperature zone of three parts, adopt unique thermal structures and heat storage effect, perfectly still, the object under test in testing the application of cold and hot wind road, switching, automatically open the high temperature and low temperature impact test OuDeFeng valve so as to achieve the high temperature and low temperature impact test. The temperature measurement: imported from level 1 PT100 platinum resistance temperature measurement body 3 only, induction heat trough respectively, cryogenic tank and the temperature of test operation and responsive, testing accuracy.

High and Low Temperature Dampening Tester instrument inhibition refrigeration system design and application of energy regulation technology, an effective approach can not only ensure the normal operation of the refrigeration unit and under the condition of energy consumption of refrigeration system and the adjustment of the refrigerating capacity effectively, make the refrigeration system operation cost and failure rate to fall to a relatively economic state. The working principle of refrigeration: the cycle of high and low cooling is based on the inverse carcase cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: refrigerant by compressor adiabatic compression to high pressure, consumes power make the exhaust temperature, refrigerant through the condenser after isothermally and surrounding medium for heat exchange, the quantity of heat to the surrounding medium. After the cooling agent expansion of the refrigerant, the refrigerant temperature decreases. The last refrigerant is heated by evaporator isothermal from the temperature of the object to reduce the temperature of the cooled object. This cycle is repeated to achieve the goal of cooling.

High and Low Temperature Dampening Tester is applicable to electronic elements of safety performance test screening tests provide reliability test, products, etc., at the same time, through this equipment test, can improve the reliability of products and product quality control. The core technology, according to the facts stated.

Knowledge, summary of the paper core. High and Low Temperature Dampening Tester instrument inhibition refrigeration system with Europe and the United States imported compressor, and the use of environmentally friendly refrigerant. Using binary cascade refrigeration, in order to increase the service life of the equipment. Using multiple vane circulation fan, to avoid any dead space, can make the uniform temperature distribution in the test area. With overtemperature protection, leakage protection, overload protection, fan compressor overpressure, overload, over current protection, phase sequence protection device such as a safe and as much as possible to ensure the safety equipment used.

High and Low Temperature Dampening Tester instrument has automatic, high precision system circuit, any parts movements, entirely by P.L.C lock processing, high precision temperature control, all adopt P.I.D control automatic calculation. Outlet and return air taste known device detector control, the direction of the wind gate body switch time of 10 seconds, cold heat shock temperature recovery time for 5 minutes. Abnormal situation happened during operation, the screen immediately automatically show the cause of the problem and provide troubleshooting methods, and found that the input power is not stable, the emergency stop function. The high quality of YOKOGAWA temperature recorder and record the original temperature signals at the same time.

High low temperature controlling in the tester adopts the SUS# 304 stainless steel plate, box adopts the SEEC steel plate and foundation of the lacquer that bake, increase the appearance quality and cleanliness, modelling beautiful generous. Tank insulation layer adopt high strength of PU and insulation cotton, good heat preservation effect. Cabinet is equipped with a diameter of 50 mm test hole, used for external test power supply cord or signal lines, can also be produced according to customer requirements. Machine adopts high quality can be fixed at the bottom of the ground wheel, PU activity is convenient to move. The above content, easy to understand.
