Temperature shock test box in the test cycle water pressure how to do When the temperature impact test chamber has insufficient circulating water pressure in the test, we should first check 1. Is the indicator light in the display indicating that the red water is flashing? 1. Check that the cooling tower power is on? 3. Is there any damage to the cooling tower water pump motor? If the power is sent, no action, it represents the damage to the cooling tower of the motor. I. If the temperature impact test box has insufficient circulating water pressure in the test and the indication light of the circulating water in the display is red, the indicator light is flashing. Second, if the temperature impact test box in the test when the circulating water pressure is insufficient and the indication lamp of the circulating water in the display is the red indicator light is on and off, 1. Please turn on the cooling tower power supply! The failure analysis and solution to the lack of circulating water pressure in the above temperature impact test box during the test is the experience accumulated by our technical staff over the years. Temperature impact test box instructions The environmental conditions of the temperature impact test box are: Insulation body: ultrafine glass fiber cotton circulatory system: centrifugal fan, stainless steel fan Safety configuration: leakage protection, compressor over-voltage, over-temperature and over-current protection, overload protection, fan overheat protection, voice alarm, etc. The room temperature is +20°C and the circulating water level is +25°C. The sample is a plastic package integrated circuit cooling circulating water: water pressure: 0.2-0.4Mpa, water temperature ≤ 30°C
Clear tape can be divided into pure tape and transparent Color Tape, generally without printing.
From the use, transparent tape includes stationery tape, transparent office tape, other packaging tape. The inner ring paper tube of the roll can print the company's designated text, including all announcements that are not specific to specific objects, including public service advertisements and travel advertisements, commercial advertising, etc., to achieve the effect of promoting goods, services, or ideas, determine the tape producer. We support the production and sale of small batches and large quantities, but the color of the specifications is uncertain. If you have an idea, you can send it to me and we will do it together.
If you have other requirements for tape, maybe you could look at the custom tape.

Second, if the circulating water pressure is insufficient, the fault indicator shows that the red indicator lights up and does not blink. The reasons for this situation are very numerous. Please check one by one according to the following items:
2. Check the cooling tower for water?
After analyzing the cause of the failure, we will find the next solution.
On behalf of this period of time, the following 1 and 2 cases have occurred. However, the fault signal has been automatically excluded at this time.
There are many reasons for this situation. Please exclude them one by one according to the following items:
2. Please check if there is any problem with the cooling water tower replenishment system and if the water inlet part is on!
3. Please inform the hydropower bank to replace the motor.
4. If not, please carry out maintenance, it is recommended to go outside to freeze maintenance!
Temperature impact testing machine is suitable for the test of cold and heat impact on the product parts and materials
