Hot and cold impact test
box in the high temperature experiments, such as temperature change of the experimental temperature, household electric appliances to test system software, each fault detection.
Such as temperature rises slowly, you need to query the wind the respiratory system, look at a draught adjustment of circulation system partition is open all normal, on the contrary, to test the wind circulation system of the motor is running normal.
Such as the set values for the temperature overshoot powerful you must set the main parameters of PID.
If the temperature rise immediately, over temperature protection, then control board out of the common faults, changing a control instrument.
Hot and cold impact test cases in the experimental operation in the whole process of common failure, suddenly appear on the control instrument match display information to remind the common failures and voice alarm to remind.
Actual operation staff can compare the equipment in the practical application of the common faults chapter quickly detect which belongs to a kind of common failures, can please technology professional staff fast fault detection, to ensure the normal in the experiment.
Other natural environment laboratory equipment in the application will continue to have other conditions, it needs to actual situation, the thorough analysis and clear.
Natural environment laboratory equipment to carry out maintenance on time, refrigeration unit cooler to clear in time, in view of the theme activity components should be in accordance with the instructions to oil RunHua, household appliances maintenance of automatic control system test these, is indispensable in this work.
When hot and cold impact test cases of cryogenic not experiment on parameter values, so you need to observe the temperature change, the temperature drop slowly, or the temperature to a certain value, the development trend of temperature has warmed in front of a need to have a check, ultra-low temperature experiment is the personal studio before drying, keeping a personal studio dry mania will try experiments into work again after the room to do the experiment, the work of the sample (s) experiment is placed inside the room too much, make the job of the wind inside the room may not be adequate circulation system, after clear stated reason, will need to consider whether refrigeration unit is one of the common faults of that would need to please the manufacturer's technical professional maintenance staff to carry out.
The status of the latter is the application of equipment natural environment is not very good, equipment placed the working temperature, the site of implantation (
And after the shell wall spacing)
To conform to the requirements (
In the actual operation equipment are required on the manual)
Hot and cold impact test chamber
heat experiment, a specific environmental humidity will be 100% or specific environmental humidity and overall target environment humidity is very large, apart many values that are lower, in front of a situation: may be dry bulb temperature sensor on the dry sand cloth manic, it needs to test the dry bulb temperature sensor is less water in the stainless steel sink, stainless steel sink in the water level automatic control system is composed of a liquid level controller, liquid level controller is water supply equipment power supply all normal, liquid level controller is normal work.
Another will is dry bulb temperature sand cloth for long time, or the power supply of water purity can make sand cloth and hard, make the sand cloth can't digest absorb moisture and dry rashness, if changing or cleaning sand cloth can remove above condition.
The status of the latter is mainly humidifying system software does not work, the query humidifying system software of water supply equipment, water supply equipment is in a certain water flow, the manipulation of humidification heating furnace is the manipulation of the water if everything is normal, humidifying reheating furnace, the water level is normal.
If above everything is normal, it needs to test automatic control system for household electrical appliances, this should please technology professional maintenance staff to carry out the maintenance.
The interpretation of the above is the common failure analysis of heat and cold shock test chamber, the hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline (
