Thermal Shock Tester Entire Design Process
Thermal Shock Tester selection of high-quality materials, the use of the current state-of-the-art processing equipment processing, shell surface spray treatment, beautiful, smooth. Color coordination, angular design, smooth lines and natural. (SUS304), the insulation material is polyurethane foam and glass fiber, the design is reasonable and durable. The stainless steel plate (SUS304) is made of stainless steel plate (SUS304) Thermal Shock Tester in line with the premise of national standards, all aspects of performance are stable on the basis of more practical and easy to control. Moreover, the device has easy to install, simple operation, security device settings so that users in accordance with the normal operating procedures under the premise of no worries. Thermal Shock Tester can achieve high temperature, low temperature in the moment of the cycle of change, today's box design can be classified as: two-box Thermal Shock Tester and three-box Thermal Shock Tester.
The two-compartment type temperature impact test chamber is divided into high-temperature zone and low-temperature area. In the course of the Thermal Shock Tester test, the sample was placed in the hanging blue and was suitable for the small sample to be tested. For the sake of design reasons, the hatchback type impact test chamber was not detectable for fragile samples.
Three-side Thermal Shock Tester from the structure point of view can be divided into three areas, the above is the high temperature zone, the middle is the sample area, the following is the low temperature area, the test sample placed in the sample area, through the control device to adjust the conversion can be automatically adjusted Experimental temperature impact test.
The two-box design principle is derived from the time point (<= 5min) in the instantaneous change requirement of the high temperature and low temperature environment. By placing the test sample in the basket, the two zones are running separately to realize the instant of the ambient temperature Variety.
Three-box Thermal Shock Tester design principle is to place the product in the medium temperature area, and then the high temperature or low temperature environment into the pilot area, thus changing the temperature environment in the temperature zone, this design can be two-box Thermal Shock Tester can not be in the temperature of the temperature impact test standards, the current production of Thermal Shock Tester mostly to three main.
Thermal Shock Tester design comes with the following perfect features:
1, the perfect protection of the alarm function: When a short circuit, leakage, studio overheating; compressor overpressure, overload, oil pressure, water and other abnormal conditions, the screen immediately automatically shows the cause of the malfunction and provide exclusion methods and Found that the input voltage instability, with an emergency shutdown device, hot and cold impact structure movement time in 10 seconds;
2, Thermal Shock Tester hot and cold impact temperature recovery time in 5 minutes, can meet the MTL, IEC, JIS, GJB and other norms;
3, can be extended Thermal Shock Tester equipment: temperature recorder, Ln2 rapid cooling control system, RS-232 communication interface device, with the personal computer at the same time on-line monitoring and recording of local area network.
Thermal Shock Tester Refrigeration System Compressors are equipped with single-phase motors similar to refrigerators and are generally of four types:
(1) Impedance Split (RSIR) Thermal Shock Tester for smaller cooling capacity.
(2) Capacitive phase separation (CSIR) In the starting winding in series with a starting capacitor, used to improve the motor starting torque, generally used in the cooling capacity of 12560kJ / h or so Thermal Shock Tester.
(3) capacitor start, capacitor running (CSR) This type of motor is in the circuit, the running capacitor and the starting capacitor in parallel, when the start process is completed, the starting capacitor cut off from the circuit, the starting winding is still connected with the running winding , So that the starting winding can withstand a part of the load, the small running capacitor can improve the motor power, improve the efficiency of reducing the current, this motor is usually used for more than 0.75kW Thermal Shock Tester refrigeration system compressor.
