Battery-specific temperature cycle test chamber Chiller tips
With the rapid development of the economy, the new energy automobile industry has also achieved rapid development, and the requirements of the battery industry are also getting higher and higher. In order to adapt to related industries, LNEYA has developed and produced the battery-specific temperature cycle test chamber Chiller, which has won the favor of large domestic and foreign companies. Therefore, today Xiaobian made a description of the use of the battery-specific temperature cycle tes...
View detailsApplication of Screw Water Chiller
The power of screw water chiller is relatively larger than that of scroll chiller. It is mainly used in central air conditioning system or large industrial refrigeration. It can be divided into two categories. 1.Twin-screw refrigeration compressor is an energy-adjustable fuel injection compressor. Its three continuous processes of inspiration, compression and exhaust are realized by periodic volume change of a pair of intermeshing Yin and Yang rotors in the body when they rotate. Generally, t...

1. After power supply is switched on, the air switch of the main power supply is automatically disconnected.Elimination method: Check whether the compressor of refrigeration system is damaged or not, and replace the parts if damaged. After replacing the fittings, turn on the machine to check whether it is normal. The fault is usually caused by unstable power supply, because the * stage starts first, so the damage is usually in stage. In this case, as long as the delay regulated power supply i...

Motor test bench test and temperature system for vehicle components
All vehicle components must undergo rigorous testing, but safety programs must undergo more stringent durability and terminal testing. Many physical methods can be used to load the motor, but the small motor test bench is favored for its high speed, flexibility, and ability to reverse the test piece at high speeds. The test bench is an AC power dynamometer with four-quadrant operation capability and can work independently in the speed or torque control mode. The system is equipped with a benc...

Motor test bench environmental cabin option for new energy vehicles
Passenger car motor and commercial vehicle motor test bench can complete the stall torque and locked rotor current test, temperature rise test, continuous electric working characteristic test, motor maximum speed test, motor over speed test and feed operation characteristic test. At the same time, the test bench can feed the electricity generated during the test to the company's power grid through the frequency conversion system. Motor labs and performance dynamometers must contain functions ...
View detailsAnalysis of Advantages and Disadvantages of Screw Water Chiller
Compared with other types of chillers, the overall energy consumption of high-quality screw water chiller is relatively small. Because the production technology of screw water chiller is more advanced and less energy is used, the equipment can quickly realize the purpose of reducing space temperature. The more screw water chillers are used in enterprises, the stronger the ability to reduce space temperature per unit time is, thus providing conditions for enterprises to reduce energy consumpti...
