Instruments and meters users to the century talent training Yin currently used in the intelligent adaptive CNC research force measuring device dynamometer mainly depends on imports, the price is expensive. Insufficient sensitivity of the signal The insensitivity and hysteresis of the signal bring certain difficulties to the analysis and processing of the signal, which needs to be solved by using the time series predictive control theory. The adaptability of adaptive algorithms is not comprehensive. The application research of current adaptive algorithms is mainly limited to linear, time-invariant and deterministic systems (simplified).
In general, the actual machine tool is a certain degree of nonlinearity (such as viscous friction), time-varying (such as system gain varies with processing time) and uncertainty, so the simplified adaptive algorithm can not meet the actual processing control requirements. Real-time control problem The plug-in adaptive control system can use the additional microcomputer for parallel computing, and there is no obstacle in real-time. However, the intelligent adaptive control of the numerical control system will occupy the interpolation time due to signal analysis and control optimization. Need to solve its real-time problem.
The high-speed CNC turret punch press is a high-end equipment used for pressure processing. It can make the metal receiving date: 2 (X) 7 - 0 1 pressure 1 5, the development history of CNC punch press CNC turret punch press, as the key to sheet metal stamping processing Equipment has been applied and developed for nearly 50 years. Among them, the main transmission components as the power source for the press have also undergone several stages of changes and developments.

Water treatment Filter Element is a filter element used for water treatment and liquid filtration. It is mainly used to remove suspended solids, sediment, rust and other impurities in water, and improve the cleanliness and transparency of water. The filter element is divided into the following types: PP filter element is also called PP melt-blown filter element, which is a filter element made of polypropylene material, which has good filtering effect and corrosion resistance, and can be used to purify tap water, groundwater, chemical liquids, etc.; The wound filter element is refined by finely winding textile fiber yarns with good filtration performance on a porous skeleton. The yarn materials include polypropylene fiber, acrylic fiber, absorbent cotton fiber, etc. By controlling the winding tightness and thinness of the yarn during winding, filter elements of different precision can be made, which can effectively remove suspended solids and particulate impurities in various liquids, and have a high purification effect on various liquids; folded filter elements , is a deep filter core folded structure, large membrane filtration area, large flux. Low differential pressure, strong dirt holding capacity and long service life. There are a variety of filter fineness to choose from, with a wide range of applications. Good chemical compatibility, suitable for filtering strong acids, strong alkalis and organic solvents. Processed and formed by hot-melt welding technology, does not contain any chemical adhesives, no leakage, no secondary pollution.
