1.IntroductionIn China's ceramic industry, ball mills are used in large quantities and are indispensable important production equipment for material crushing. The ball mill generally has a large power. The system adopts simple power frequency control, requires long grinding cycle, low grinding efficiency, easy over-grinding of materials, and large power consumption per unit product, thus becoming one of the largest power-consuming devices in the ceramic industry. . At the same time, the starting current of the system is large, which has a great impact on the equipment and the power grid, resul...

1.IntroductionAt present, most of the centrifuges used in domestic sugar factories are variable-speed speed-regulating centrifuges. This type of centrifuge has a slow speed increase. The brake uses a brake brake to impact the motor, the motor is easily damaged, and the auxiliary time is long. The noise is high, which limits the increase in production capacity. Since the sugar factory is in an economically underdeveloped area, self-generated electricity, large grid voltage fluctuations, small margins, and strong seasonality of materials require equipment to maintain high productivity, high reli...

1.IntroductionCentral air-conditioning is one of the indispensable supporting facilities for modern large-scale buildings. According to statistics, the consumption of electric energy accounts for about 50% of the total consumption of buildings. The central air conditioning system is designed to increase the load by 10% to 20% according to the maximum load. Due to seasonal, day and night and user load changes, the actual load is much smaller than the design load, and the full load running time is less than 1%. Although the load of the central air-conditioning main unit can automatically adjust ...

1. The necessity of servo casting of die casting machineThe full hydraulic die casting machine is a typical cyclic working equipment. It can be roughly divided into mold clamping, soup, shot, core pulling, mold opening, thimble, cooling, and storage in a complete working cycle (process process). Pressing several stages, each stage is to pump hydraulic oil through the oil pump motor to each cylinder to drive the transmission mechanism to complete a series of actions, each stage requires different pressure and flow. For the hydraulic system, the pressure and flow matching are different at each s...
