Six ways to teach you to extend the service life of high and low temperature damp heat test chamber
The high and low temperature damp heat test chamber is very common in environmental reliability tests, and it is also very important in testing the reliability of samples. The high and low temperature environmental test chamber can be used to assess and determine the changes on the surface of electrical and electronic products or materials under temperature cycling conditions. The automobile environment simulation laboratory can simulate the test environment of engine cold start, automobile high and low temperature, wind, frost, rain, snow, vehicle emission test, etc. Once the test box has refrigerant leakage, it will affect its use effect and even affect the service life of the test box.
5. If manual handling is used, please note that the high, low temperature, damp and heat test box cannot be tilted more than 45 degrees under any circumstances. Otherwise, it is very likely to cause damage to the compressor.
6. If there is no cooling or heating, consider supplementing refrigerant.
The above is about the use and routine maintenance of the damp heat test chamber. I hope to help you learn more about the equipment, so that it can be used and maintained more appropriately during use. For operators who encounter various problems during use, please contact the equipment manufacturer as soon as possible and operate under the guidance of professionals.
If you need to purchase test cabin equipment, one of the earliest manufacturers that produced and sold test equipment, has rich production experience, complete service system, has a good reputation in the industry, and has been committed to bringing customers high-quality services. Welcome customers in need to come to consult!
The rain test chamber is suitable for the protection of aviation, automobiles, home appliances, external lighting and signal devices, and automobile lamps and lanterns. The rain test is divided into the swing tube water spray test and the sprinkler water spray test.
1. Test purpose:
1. Whether the rainwater drainage system is effective.
2. The equipment is physically damaged due to rain;
3. The ability of the equipment to meet its functional requirements during or after exposure to rain;
4. The effectiveness of the protective cover or protective shell to prevent rain seepage;
2. Technical characteristics of the rain test chamber:
1. The comprehensive control system and the adoption of frequency conversion technology enable the automatic adjustment of rainfall, the rotation angle of the sample rack, the swing angle of the water spray pendulum, the amount of water spray, and the swing frequency.
2. More than 000 rainfall holes are evenly arranged on the top plate to make the drip distribution very even.
3. With scientific design, the equipment can provide realistic simulation of dripping, spraying, splashing, spraying and other environments.
Friction testing machine, beautiful appearance, convenient operation, powerful function, stable and reliable performance, can be widely used in various metal, non-metal and composite materials, such as wood, wire and cable, paper, rubber, medicine, food packaging materials, etc. for stretching The performance index test, a variety of tests can be realized by one machine, which is the best choice for customers.
The inspection machine, as a product of the combination of modern electronic technology and mechanical transmission technology, integrates the functions of stretching, bending, compression, and shearing. It is mainly used for the mechanical performance test of metal and non-metal materials. It is an industrial and mining enterprise, scientific research unit, The ideal testing equipment for colleges, engineering quality supervision stations and other departments makes full use of the large-scale precision testing instruments formed by the respective advantages of electromechanics, and has the characteristics of wide measurement range, high precision, and fast response.
The friction testing machine does not consume oil, so it is cleaner and easier to maintain and use. At the same time, its test range can be adjusted, which is more flexible, has high force measurement accuracy, light weight, and large space. It is convenient to add corresponding devices for various material mechanics tests. It can be said that it is truly a multi-purpose machine.
When considering cost and quality factors for an IP PBX vs. Cloud based PBX, I would first say that there are cases where a premise based IP PBX is a good choice. This would be the case when a company has a large amount of intra-company calls from the same geographical location.
This is due to the fact that calls on the same network with an IP PBX do not have to use the Internet, just the internal network. Another case where IP PBX makes sense is if the customer already has a significant and recent investment in hardware. So, for example if a customer has an PBX, it may make sense for them to simply adapt it to SIP using an IP Office. can then supply SIP trunks for the IP Office, and provide backup call paths giving them the best of both worlds.
