There are many types of environmental testing equipment, but the most common environmental testing equipment is high temperature, low temperature and humidity test chamber, and now more popular is the test chamber that integrates high temperature, low temperature and humidity—hot and cold shock testing machines In addition to the correct operation according to the operating instructions, the test personnel should also understand their structure.
The thermal shock testing machine consists of a cabinet, an air circulation system, a cooling system, a heating system and a humidity control system. The air circulation system generally adopts a structure that adjusts the direction of air supplyn can; the humidification system has two types: boiler humidification and surface evaporation;
The cooling and dehumidifying system adopts the cooling structure of the air conditioner ; the heating system adopts the electric heating There are two structures: heating and electric furnace wire direct heating; the temperature and humidity test method adopts the wet and dry bulb test method, and the direct measurement method of the humidity sensor is also used;
To ensure that the mechanical equipment is always in good technical condition and can be put into operation at any time. To improve mechanical integrity and utilizationn to reduce mechanical wear, increase mechanical life, reduce mechanical operation and maintenance costs. In order to ensure safe production, it is necessary to strengthen the maintenance of thermal shock testing machine equipment:
1 The maintenance of the thermal shock testing machine should ensure the quality , carry out point by point according to the specified points and requirements, and no guarantee is not missed or not guaranteed. Maintenance points, maintenance quality and problems found during maintenance must be recorded.
2. Maintenance Personnel and maintenance departments should Three Inspections and one delivery”, continuously summarize maintenance experiences and improve maintenance quality.
3. Each team must do a good job in the maintenance of various machines according to the machines maintenance regulations and maintenance categories, without undue delay, special circumstances Maintenance can only be postponed after the approval of the responsible officer but generally should not exceed half of the prescribed service interval;
