Compressor maintenance of high and low temperature test chamber

The high and low temperature series test equipment we are talking about here includes: high and low temperature test chamber, high and low temperature alternating test chamber, constant temperature and humidity test chamber, high and low temperature humid heat test chamber, temperature shock test chamber, etc., the same refrigeration core of these equipments - -compressor. The quality of the equipment test system is directly related to the control performance of the compressor. The refrigeration compressor is the core component of the temperature tester, and the maintenance of the compressor is particularly important. Below, we will test the compressor maintenance of high and low temperature series test equipment, and summarize the following experiences.
The first is in the laboratory environment, the need to choose a good installation site, which is the prerequisite for the correct use of the air system for the compressor of the high and low temperature series test equipment. If the test environment of the test equipment has no prior planning, it is not known that the result of such a sloppy result is the reason for the difficulty in repairing the compressor failure and the poor quality of the compressed air in the future.
1. Since the compressor has an air circulation system, if there is much dust in the environment around the equipment, a filtering device is needed. At the same time, it is absolutely not allowed to contain flammable gas and corrosive gas in the air, so as to avoid explosion or internal corrosion. On the whole, it is necessary to ensure that the relative humidity of the air is low, the ash is often small, and the ventilation is good.
2. The performance of compression should not be affected by high temperature, and the ambient temperature is lower than 30 °C. If the temperature is too high, the output air volume of the compressor will decrease.
3. The equipment should be placed in a spacious place. The narrow space is not conducive to the later maintenance and maintenance. In particular, the radiator (condenser) of the compressor's freezer should be regularly maintained and kept clean.
4. The voltage at the working space of the test box should be stable, otherwise the current will be too large or too small. Working under these conditions will cause damage to the compressor.
5. The test box should be built on a hard floor. The foundation plane should be leveled before installation to avoid noise caused by vibration of the compressor.
High and low temperature test equipment during the test, correct operation and reasonable handling of faults, is conducive to the maintenance of the compressor and extend the service life.
1. It is not advisable to start the compressor frequently during the test. The interval between compressor start-up is 15 minutes.
2. When the equipment is in trial operation, strictly check the running direction of the compressor. When it is found that the reversal should be stopped immediately, cut off the power supply, and turn any two of the three-phase lines back and restart, otherwise the compressor will be damaged.
3. During the work of the test equipment, the protection system of the compressor safety valve is regularly checked to ensure its sensitivity and reliability.

Matting Agent For Plastic Coatings

Description


1, Matting Agent popular used for the matte plastic coatings. It is synthetic amorphous micronized precipitated silica appearing as white powder and for both solvent-based and water-based system. Advanced matting efficiency is achieved by using silica with high pore volume and by fine control of the particle size and particle size distribution. It provides a superior matting and flatting, excellent coating appearance and transparency, cost efficient, effective anti-settling agent and easy dispersion, smooth, abrasion resistant films of high surface quality. Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability.

2, Silica Matting Agent suitable used for plastic coatings. It provided high matting efficiency, excellent coating appearance and better transparency. As well as low oil absorption, easy dispersion and smoothly touch with minimal impact of viscosity.
