2023-01-3134200Role of mechanical transmission: The role of mechanical transmission is to transmit motion and force. The types of commonly used mechanical transmission systems include gear transmission, worm gear transmission, belt transmission, chain transmission, gear train, etc.Gear transmission: gear transmission is realized by shifting the driven gea...
2023-01-3133500The laser control system is a kind of numerical control system. Its principle is to execute the control function according to the program stored in the board. The laser control card is the "brain" of the laser equipment. All the instructions of the machine operation are transmitted to the machine through the control card. The excellent control card...
2023-01-3028400Hydraulic transmission uses hydraulic oil as the working medium for energy conversion and power transmission. It has the advantages of large energy transmission, easy layout, compact structure, convenient commutation, smooth and uniform rotation, and easy to complete complex actions, so it is widely used in the field of construction machinery. Howe...
2023-01-3029900In use, the hydraulic transmission device may have many problems such as abnormality and leakage. In addition, during the operation of the equipment, many problems such as over-temperature will often occur, which will have a negative impact on the liquid in the equipment and reduce the characteristics.1、 Basic principle of hydraulic control...
2023-01-3028700The performance of AC servo motor is better, because AC servo is controlled by sine wave, and the torque ripple is small; The brushless DC servo is controlled by trapezoidal wave. But brushless DC servo control is relatively simple and cheap.The rapid development of permanent magnet AC servo drive technology makes the DC servo system face t...
2023-01-3043300Each type of motor has its own specifications. When selecting the type, it is necessary to follow the steps. Select according to its running speed, weight and other data, so as to select the product suitable for you. When selecting the servo motor specification, follow the following steps.(1) Specify the requirements for the movement condit...
2023-01-3034800The condenser of the industrial water chiller is a heat exchange device. Its function is to use the environmental cooling medium (air or water) to take away the heat of the high temperature and high pressure refrigerant steam from the compressor, so that the high temperature and high pressure refrigerant steam can be cooled and condensed into the r...
2023-01-3044800The water chiller is a kind of water cooling equipment, which can provide constant temperature, constant flow and constant pressure. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, and the water is cooled by the chiller cooling system. Then, the water pump inside the machine will inje...
2023-01-3034200In cooperation with researchers from Germany, France and other countries, the Siberian National University of Russia has developed a pocket fiber laser doped with rare earth metal thulium, which can produce 1600~2500 nm wavelength laser and regulate the laser wavelength within a certain range, but does not affect the stability and power of the lase...
2023-01-3034301According to the latest news from foreign media, Luminar Technologies, an American manufacturer of lidar sensors, plans to establish a new factory in Asia and will seek to reduce the cost of each lidar sensor to $100.It is reported that Luminar outsourced the production of its lidar sensor to Celestica, a Canadian electronics manufacturing ...
