How to quickly and troubleshoot high and low temperature impact test chamber failures During the use of high and low temperature impact test chamber failure is difficult to avoid, although some small faults will not affect the life of the test chamber, but will still be the original test plan for the operator Have an impact. Even the leading companies in the ring test industry can't say that their test equipment will never fail. Therefore, Xiaobian specially asked our technicians about the faults that can be solved by themselves and the corresponding solutions. I hope to give some help to the users.
1. It can be processed according to the judgment judgment displayed on the control instrument, or it can be handled by professional technicians for safety reasons.
2. When the low temperature test is carried out, the test chamber cannot reach the set temperature, so it needs to be observed because of the slow temperature drop or because of the rebound after reaching a certain temperature. If it is the former, you need to check if it is because the studio is not dried before it is carried out. If it is caused by the second reason, then it is necessary to check if the sample inside the studio is too much, so that the internal air cannot be fully circulated. If it is not the fault caused by these two reasons, then you need to find a professional technician to check.
3, high and low temperature impact test chamber refrigeration Compressor Unit pressure is low, the actual gas consumption is greater than the refrigeration unit output gas volume; deflation valve failure; intake valve failure; hydraulic cylinder failure; load solenoid valve failure, zui small pressure valve stuck; user tube There is leakage in the net; the pressure setting is too low; the pressure sensor is faulty; the pressure gauge is faulty; the pressure switch is faulty; the pressure sensor or the pressure gauge input hose is leaking;
4, the refrigeration compressor unit can not start, the fuse is broken; the temperature switch is broken; the wiring is loose; the main motor thermal relay action; the fan motor thermal relay action; the transformer is bad; no power input; the fault is not eliminated; the controller is faulty.
5, fan motor overload, fan deformation; fan motor failure; fan motor thermal relay failure; loose wiring; cooler blockage; exhaust air resistance.
6. When using the high and low temperature impact test box for high temperature test, the temperature can not reach the set temperature value, then we need to check the electrical system of the equipment first to remove the fault. If it is caused by slow heating, then check the air circulation system to see if the windshield is normally open. Otherwise, you need to check if the motor is running normally. If the temperature rises directly, causing the over-temperature protection device to alarm, then it is possible to control only the system and need to be replaced by the manufacturer. Do not worry about the failure of the high and low temperature impact test chamber. First, please handle the fault with the common fault table. If you still can't solve the problem, please call the professional maintenance personnel.
The main purpose of poultry chilling is to suppress the development of pathogenic microorganism and spoilage microorganism. Many researches show that the two microorganisms on the surface of carcass are largely reduced after chilling process. There are two main chilling method: water chilling and Air Chilling. At first, people tend to adopt air chilling in the chicken plucking process, instead of immersed chilling and drum-type chilling, for the consideration of chilling speed. While the modern research data doesn't support this point, and it shows that the chilling speed may affect the flavor, quality and appearance of meat, and shock chilling will cut down the meat quality, and slow chilling will cause PSE meat.
in Water chilling area, it contains water screw chiller, and water cooling units(water cooling system or Ice Flaker ).for wather cooling units,it is for lower the temperature of water in the Screw Chilling, so that when pre-chilling the chickens, it can keep chickens in low temperautre(4-10°C),but different water cooling units have different effect.
also you can choose CONNECT Air chilling line. It is in one room,like a cold room. one automatic conveyor line is moving from outside to another side.and in this room,it is equiped with cold room equipment.
