The constant temperature and humidity test chamber is a commonly used test equipment, and the compressor is the core component of the constant temperature and humidity test chamber and plays a direct role in the low temperature test. Therefore, the maintenance of the compressor is usually very important. According to the experience of Dongguan Teddy equipment in the ring test industry for many years, the following maintenance and repair suggestions are summarized:
1. Appropriate maintenance space is left around the equipment, there is no strong electromagnetic radiation source nearby, the ground is flat, and the ventilation is good. It does not contain flammable, explosive and corrosive gases.
2. Do not start the compressor frequently during the test, and the interval between the start of the compressor should be more than 15 minutes;
3. Ensure that the working environment is well-ventilated and free from dust. Keep the surface of the compressor clean. If you do not use the constant temperature and humidity test chamber for a long time, you should place the equipment in a space that is as clean as possible.
4. The voltage in the workplace must be stable. If the voltage is unstable, the current will be too large or too small. Running in this environment for a long time will cause great damage to the compressor. It is recommended to use a voltage regulator to connect the constant temperature constant. Wet test chamber
5, constant temperature and humidity test chamber should be placed in compliance with the prescribed environment: temperature: 5 °C ~ 30 °C, humidity: ≤ 85% RH, pressure: 86 ~ 106kpa
If you do the above points, you basically master the maintenance of the compressor. It will ensure that your normal equipment operates and effectively extend the service life of the equipment. If the compressor of the constant temperature and humidity test box is faulty, please inspect and inspect the professional technicians.
Mixing Machine, in a word, is a kind of machine to mix two kind of materials or more than two kind of material together in a ratio. There are several types of mixers using for mixing powder and small granule.
Mixing machine includes:
Ribbon Blender:The outer ribbon push the material from the two ends to the centre, inner ribbon push the material from center to the two ends.Thus to achieve material convention
The discharging port is set in the bottom centre, with the help of the outer ribbon,the material can be discharged completely, and no dead zone.
Double screw cone mixer: double screw cone mixer is a convective mixer with high mixing efficiency. It is gentle and guarantees the highest level of mixing accuracy without product distortion.
The rotating cantilevered (free hanging) mixing screws convey the product from bottom of the vessel to the product surface. The mixing screws are suspended from an orbital arm, which rotates the mixing screws along the conical inner vessel wall causing convective mixing of particles and shear.
The speed of particles in the downward massflow when recirculated by gravity in a conical vessel increases as the vessel diameter decreases. The result of these simultaneous actions is a fast and intensive mixing with low consumption of power together with high standards of mixing accuracy.
double screw cone mixer is widely used for mixing and homogenization of powders and pastes in food, chemical and pharmaceutical industry.
