Our company has a hot and cold shock test chamber, always leaking oil, what is the solution?

The thermal shock test chamber is used to test the degree to which a material structure or composite material can withstand a continuous environment of high and low temperature in an instant. As a high-precision, high-efficiency environmental test equipment, the thermal shock test chamber is relatively cumbersome to troubleshoot and solve due to the complexity of its own system and process. The main faults and troubleshooting methods of the thermal shock test chamber:

1.Control interface display: three-phase power supply phase sequence error checking mode:

1. Is the part of the three-phase power supply phase sequence error fault displayed in the red indicator light not flashing state?2. Is the part of the three-phase power supply phase sequence error fault displayed in the flashing state of the red indicator light?Solution:

1. This situation usually occurs when the equipment is positioned or moved for the first time, and two of the three lines of the three-phase power supply can be reversed

The thermal shock test chamber is used to test the degree to which the material structure or composite material can withstand in an instantaneous continuous environment of extremely high temperature and extremely low temperature, so as to test the chemical changes or physical damage caused by thermal expansion and contraction in the shortest possible time, and confirm the quality of the product.

Cultivation of oil sources:

1. Regularly search whether there is an oil leak between the main engine and the oil source, and if an oil leak is found, the sealing ring or combination gasket should be changed in time;

2. According to the application of the machine and the service period of the oil, change the oil suction filter and filter element on a regular basis, and change the hydraulic oil.

3. When it is not implemented for a long time, turn off the power supply of the host steadily. Assuming that the machine is in standby mode, the transfer switch should be hit to &ldquo, constant temperature and humidity test chamber; Loading"gear, because if the transfer switch is hit"Rewind"The solenoid reversing valve does not stop in the energized shape, which will affect the service life of the device.

I know several powerful manufacturers, such as Ruikai Instrument, Binde, production experience, quality, and service are first-class.

The specific solution can be directly called the manufacturer, or find the technical engineers of the Yutai test equipment - thermal shock box manufacturer, they will be very patient to help you solve the problem, they are also from the manufacturer.

In recent years, the rapid development of the thermal shock test chamber has brought safety to people in the use of products, so many manufacturers have slowly come into contact with the test chamber, but as long as the equipment will have a failure, what we have to do is to maintain the equipment to reduce the incidence of failure.

Common faults and treatment methods of thermal shock test chamber:

1. When the temperature of the test chamber does not reach the test temperature value, we need to check whether there is a problem with the electrical control system.

2. When the temperature of the thermal shock test chamber rises very slowly, the air circulation system of the chamber should be carefully checked to see if there is a problem.

3. When doing the damp heat test, if the low temperature does not reach the test index, we should first observe the temperature change, if the temperature drops very slowly, we should consider whether the studio has been dried before the low temperature test.

Fourth, the poor ambient temperature will cause machine failure, so when conducting the test, you must choose the best approximate temperature for the equipment is 5-27 degrees, and the humidity is about 95%.

Fifth, if the actual humidity and the target humidity value are very different from the actual humidity value when doing the damp heat test, we should first check whether the humidification system is working, and then check whether the water supply system of the humidification system contains a certain amount of water, whether the water level control is normal, if everything is normal, then we must ask professional maintenance personnel to overhaul.

The life of the equipment is often because of whether the user has done a good job in the maintenance work in ordinary times, so we must operate in strict accordance with the manufacturer's instruction manual when using the equipment, so that we can extend the life of the equipment.

This problem can be dealt with by the manufacturer or given treatment advice.

But according to my estimate, it is not necessarily an oil leak, this kind of machine, the main part with oil is: the refrigeration system, but if this part leaks oil, the machine will not be used for a long time.

So, the biggest possibility is a water leak. There are 2 parts of water leakage, pre-cooling room or unit room (condensate); If the manufacturer has oil remaining in the unit room in the early stage, the leaked water will have a layer of oil on it, much like oil.

It is best to determine whether it is a water leak or an oil leak, it is not a small problem, but the oil leakage is more serious, and if the oil leak is not repaired by the manufacturer, you can declare that your machine can be scrapped.
