The use of high and low temperature chamber precautions and follow-up care

High and low temperature test chamber is mainly used for parts and materials of related products such as LED, plastic, hardware and metal, aerospace, electronic electrician, auto motorcycle, colleges and universities, research institutes, etc. under the condition of high temperature, low temperature (alternating) cyclic change. , test its performance indicators. It is a necessary test equipment for a large number of enterprises and colleges and universities.
When using a high-low temperature chamber, we need to pay attention to the following points:
First, the high and low temperature test chamber sticks to professional management. Our company will send professional engineers on-site commissioning and use of training work. If the customer company personnel changes greatly, the customer needs our company to arrange engineer homework training again to obtain more professional maintenance and repair. The experience and ability of the high and low temperature test chamber suggest placing it in a relatively benign temperature environment. The optimal ambient temperature and humidity is: 5°C~+30°C≤85%RH. For laboratories or factory workshops that do not have this condition, Equipped with an appropriate air conditioner or cooling tower. To ensure the life of the compressor and the overall experimental results of the machine.

Second, high and low temperature test chamber circulating fan, condenser fan cleaning and balance: similar to the cleaning of the evaporator, due to the different working environment of the test chamber, the circulating fan and the condenser fan will gather a lot of small particles such as dust, should Regular cleaning, waterway and humidifier cleaning: If the waterway is not smooth, humidifier fouling can easily lead to humidifier dry, may damage the humidifier, so you must regularly clean the waterway and humidifier.

Third, regular cleaning of high and low temperature test boxes to ensure good ventilation and heat transfer performance. For compressors using water-cooled cooling, in addition to ensuring that the inlet pressure and inlet temperature, it must also ensure that the corresponding flow and regular The inside of the condenser is cleaned and descaled to obtain its continuous heat exchange performance. The relocation should be carried out under the guidance of the technical personnel of Hongda in order to avoid unnecessary damage or leakage of refrigerant, etc. The inner wall should be cleaned if it is not used for a long time. Clean, keep dry, and power the device once every half-day for no less than 1 hour.

4. Our company promises that our customers will arrange engineers to provide free on-site maintenance and maintenance work every quarter, as well as feedback on the use of equipment and customer suggestions.

Meticulous division of labour, consecutive processes, professional of manufacture and high standard equipment ensure the high quality of the machine. 

Factory introduced high precision maching tools, with the equipment of cutting machine tools, heattreating facilities, check out test sets and painting facilities, the processing ability for middle and large size machine, reach a high level in plastic industry while the quality if the machine is ensured at the same time. 

The large size machine can produce different design of chairs. 

Vertification of many year's market application, optimal combination configuration, stable, reliable and durable system with the characteristics of high efficiency, energy saving, low voice and strong power. 

The strengthening design of template is carried out through multiple times of optimization design of major components such as template, based on the analysis of finite element software, which both guarantee the lifetime of template and protected mould. 

High rigid template adopts the structure with coexistence of installation screw hole and T-shaped groove. 

The tie rod of each machine model has passed the test by professional testing organization, which means that, the deflection of tie rod is within reasonable scope while guaranteeing the operation of machine.
