Precautions for regular maintenance of Temperature Humidity Chamber

What are the reasons for the short life and aging of the high and low temperature test chamber?

The main factors that lead to the shorter and aging of high and low temperature test chamber are the temperature, the surrounding light, and the humid surrounding environment. Therefore, LISUN recommends that the equipment is placed in an environment with constant temperature, dryness, and direct sunlight.
1. Environmental temperature: Because the operation of the equipment will generate high temperature and increases the surrounding temperature, this will increase the strength and damage of the light at this time. Therefore, it is necessary to grasp the range of temperature during equipment work.

2. Surrounding light: The structural materials of different products at high and low temperature test chamber are also different from the strength of light. Therefore, when purchasing, the shape of the shape is considered. Generally, the equipment is treated with SUS304 stainless steel.

3. The surrounding environment is humid: General moisture, rain, dew, etc. These are factors that cause moisture. The dew formed by the moisture is the main factor for outdoor humidity. The time is longer, causing more wet absorption, so it is necessary to consider ventilation during installation.

So how to keep of high and low temperature test chamber?

1. Clean at least once a week in the equipment. When cleaning, first wipe it with soapy water. The inspection and maintenance of the instrument humidifier, storage in the humidifier should be replaced once a month to ensure that the water quality is cleaned once a month. Wash the moon once to ensure the smooth flow.

2. The condenser should be maintained regularly to keep it clean. Dust sticky condenser will make the compressor high -voltage switch escape and generate a mistaken alarm. The condenser is also suitable for monthly maintenance. Use a vacuum cleaner to remove the dust attached to the condenser mesh. Or blow the dust with a high -pressure air mouth.

3. Each test is over, clean the test chamber with water to keep the equipment clean; after the chamber is cleaned, it should be dry to dry the chamber and keep the chamber dry.
4. The water level of the water tube should not be too high, so that the water overflowing the water tube or too low will cause the water test cloth to absorb the water abnormally, resulting in the accuracy of the wet ball. The water level can be kept at about six minutes. The water level of the water tube can be adjusted, and the height of the water chamber can be adjusted.

5. When the surface of the test cloth is not clean or hardened, after the equipment is controlled, the test cloth must be replaced before continuing the temperature and damp ball control. The test cloth is replaced every three months. When replacing, the cleaning cloth wipes the temperature, and it should be cleaned first when replacing the new test cloth.

The high and low temperature test chamber is a very widely used product among our many products. It is also a well -received precision instrument. If the same good instrument does not need to be well maintained, the benefits of the instrument will decrease over time over time.

The daily maintenance of the high and low temperature test chamber and the simple test of the main technical indicators can ensure that the work of high and low temperature test chamber is in a good state. The following are the matters that need to be paid attention to the maintenance of the maintenance of high and low temperature test chamber:

1. The temperature and humidity of the high and low temperature test chamber are important factor affecting the performance of the instrument. It can cause the corrosion of the mechanical parts, reduce the smoothness of the metal mirror, and cause the error or performance of the mechanical part of the high and low temperature test chamber which cause high and low temperature tests to test high and low temperature tests chamber optical components such as grating, reflective mirror, focusing mirror and other aluminum membranes are rusting, which produces insufficient light energy, mixed light, noise, etc., and even the instrument stops working, which will affect the life of the high and low temperature test chamber. It should be regularly corrected when maintaining maintenance.

2. The dust and corrosive gases in the working environment of high and low temperature test chamber can also affect the flexibility of the mechanical system, reduce the reliability of various limit switches, keys, and photochemicals.

3. After the use of a certain cycle of high and low temperature test chamber, a certain amount of dust will be accumulated internally. The maintenance engineer or under the guidance of the engineer will regularly turn on the cover of the high and low -temperature test chamber to perform the dust removal work inside. Clean the sealing window of the optical chamber, calibrate it if necessary, clean and lubricate the mechanical part, then restore the original state, and then perform some necessary detection, adjustment and records.

4. The reasons for the evaporator of the high and low temperature test chamber: (1) frequently open the test chamber door (2) Check whether there is a problem of air leakage in the chamber.

Safety information that needs to be paid attention to when using high and low temperature test chamber
Danger and personal security information
1. High temperature burns
The temperature in the chamber is very high during the high -temperature test chamber. During the test or at the end of the test, if you need to open the door, you need to be careful to avoid burns.
When the frozen machine works, please do not touch the temperature of the exhaust copper pipe during the high running temperature to avoid burns.

2. Low temperature frostbite
The temperature inside the chamber is very low during the low temperature test chamber. During the test or at the end of the test, if you need to open the door, you need to be careful to avoid frostbite.

3. Electric shock
Although the equipment has sound anti -electrical prevention measures, it still needs to be paid attention to, especially the electrical control system. In the case, do not touch the electrical part.

Install security information

1. Power supply

The power supply of the high and low temperature test chamber uses a three -phase and five -line system. Please distinguish the zero line. Due to the load and control system of the device as a single phase, the wrong line will cause the equipment to not work and damage.

The ground line is equipped with ground line columns. Ensure that the equipment is good to make the equipment safe and reliable. The error of the zero line and the ground line will cause the equipment to work abnormally.

Due to factors such as user venues, the cables are required. Make sure the rated parameters of the extended line and power supply used to meet the power needs of the product.

2. The venue

A large amount of heat will produce during the use of this device. Please install the device in a good ventilation place.

Security information

• Do not connect to the power supply of the test product, otherwise the equipment power load will be increased. Unless the device has a test power interface.
• It is strictly forbidden to test flammable, explosive, high corrosion, and strong radiation items.
• Do not carry or overhaul when the equipment is power -on or during operation.
• Do not use this device near flammable materials or explosive environments.
• Do not use in a strong magnetic field and a strong vibration environment.
