2022-11-1824800The operation of mechanical equipment will generate a lot of heat. In order to maintain the normal operation of the equipment, cooling measures must be taken. The current cooling system mainly includes water cooling and air cooling. In the field of laser marking, whether the equipment is cooled by water cooling or air cooling depends mainly on the ...
2022-11-1831400Water chiller is a kind of water cooling equipment, which provides constant temperature, constant flow and constant pressure. Its working principle is to inject a certain amount of water into the water tank in the chiller, cool the water through the chiller refrigeration system, and then transfer the low temperature cooling water to the equipment t...
2022-11-18329001、 The chiller does not start, and the indicator does not light up（1）The voltage is not normalCheck the power supply and confirm the three-phase balance（2） Fuse blownReplace fuse（3）Transformer burnt outReplace the transformer or change the power supply to three-phase four wire2、 The compressor runs continuously but the cooling capacity is i...
2022-11-1831900Laser cutting machines are generally divided into metal laser cutting machines and non-metal laser cutting machines. Non metal laser cutting machines mostly use CO2 lasers as generators, while metal laser cutting machines use fiber lasers as generators. Both types of cutting machines play an important role in industrial production, greatly improvin...
2022-11-1829400What are the characteristics of industrial chillersIn industrial production, the operation of the machine can not avoid the generation of heat. The industrial chiller is an indispensable cooling equipment. The industrial chiller generally has the following three characteristics.1、 Stable operation and strong performanceThe industrial chill...
2022-11-1828700The five most commonly used methods for frequency converter to control motor are as follows:The low-voltage universal frequency conversion output voltage is 380~650V, the output power is 0.75~400kW, and the working frequency is 0~400Hz. Its main circuit adopts AC-DC-AC circuit. Its control mode has experienced the following four generations....
2022-11-1822100Ordinary asynchronous motors are designed according to the principle of constant frequency and constant voltage, which cannot fully meet the requirements of variable frequency speed regulation. The influence of frequency converter on motor is as follows:1. Motor efficiency and temperature riseNo matter what form of frequency converter, it will ge...
2022-11-1835100All motors have a fixed operating power, which is called rated power, and the unit is watt (W). If the actual power of the motor exceeds the rated power of the motor under certain circumstances, this phenomenon is called motor overload. Overload can easily lead to motor overheating, resulting in reduced winding insulation, and ultimately motor burn...
2022-11-1824100In addition to energy conservation, intelligent motor control technology is also one of the key directions of future development. Generally speaking, the intellectualization of motor control can be realized from two aspects.First, expand the sensing range, that is, add more sensors in the motor control scheme, such as vibration sensors, to ...
