Also known as surface roughness roughness

Also known as surface roughness roughness, grinding spindle finish instrument, surface roughness tester, roughness tester, roughness tester, roughness tester, and other names, the first overseas R & D and later introduced the country. When the roughness of the surface roughness measurement, the sensor on the measured surface of the workpiece, driven by the drive mechanism inside the instrument sensors do constant glide along the surface to be measured, the sensor through the built-in stylus feel sharp measured surface roughness degrees, then the measured surface roughness of the workpiece caused by a displacement of the stylus, the amount of displacement of the inductance of the sensor coil changes the inductance, the measured surface roughness to generate an analog signal proportional to the output of the phase-sensitive rectifier, after the signal is amplified and level conversion into the data acquisition system.

The use of wind turbines, Four-Row Cylindrical Roller Bearing is an endless stream of electricity into a standard household use us, the extent of their savings is obvious, a cost of household electricity only 20 yuan a year of battery fluid. And now the wind turbines have more than a few years ago greatly improved performance, previously only be used in a few remote areas, wind turbines connected to a 15W bulb direct electricity, out of a dark and often damage the bulbs. And now because of advances in technology, the use of advanced chargers, inverters, wind power has become a certain tech small systems, and can replace the normal electricity under certain conditions. Mountainous can take the system to make a perennial street at no cost; it can be used to make highway signs night lights; mountain children can study up under a fluorescent lamp; high-rise roof wind motor city also available, which will not only save but the real green Power. Domestic wind turbines, not only can prevent blackouts, but also increase interest in life. In tourist areas, border, schools, military and even behind the mountains, wind turbines are becoming the people's purchasing hot spots. Radio enthusiasts use their own technology in wind power generation services for the mountain people, so that people watch television and lighting, electricity and urban synchronization, but also make their own labor to get rich.

Usually people think that wind power is completely determined by the wind generator power

Usually people think that wind power is completely determined by the wind generator power, always wanted to buy a bigger wind turbines, which rotary table bearing is incorrect. The current wind generator just to the battery charge, while the energy stored up by the battery, it is the size of the end-use electrical power have a closer relationship with the battery size. But mainly depends on the magnitude of power of the size of the air volume, not just the size of the power head. In the Mainland, small wind turbines would be more appropriate than big. Because it is more likely to be driven by a small amount of wind power generation, continuous small wind, wind more than momentary supply large amounts of energy. When there is no wind it can also be caused by normal use of wind energy, which means that a 200W wind generator can also be used by a large battery and inverter fit, get 500W or 1000W and even more power out.

Wind turbines due to unstable wind

Wind turbines due to unstable wind, so the output is a change from 13 to 25V AC, subject rectifier charger, and then the storage battery charging, so wind turbines to generate electricity into angular contact thrust ball bearing. Then there is the protection circuit power inverter, the battery chemical energy into AC 220V mains, in order to ensure stable use. 

Mechanical connection and power transmission couplings horizontal axis wind turbine blades are connected by high-speed shaft and the gear box and universal elastic, the torque is transmitted to the drive shaft of the generator, this coupling should have good damping and shock absorption the characteristics, the performance of an appropriate amount of the absorption offset radial, axial, and at an angle, and the coupling mechanism can prevent overload. Another is direct drive turbine blades are not directly connected to the blower motor and the motor through a gearbox type.

Light-cut method is the use of "light cut principle" to measure the surface roughness

Light-cut method is the use of "light cut principle" to measure the surface roughness.
When fatigue testing machine surface roughness, the sensor on the measured surface of the workpiece, driven by the drive mechanism inside the instrument to do constant glide along the measured sensor surface, the sensor measured surface roughness feelings through the built-sharp stylus, this the measured surface roughness of the workpiece caused by the stylus is displaced, the displacement amount sensor inductance coil inductance changes, and the measured surface roughness to generate an analog signal proportional to the output of the phase-sensitive rectifier, which signal through after amplification and level shifting into the data acquisition system, DSP chip data acquisition digital filtering and parameter calculation, measurement results on the LCD readout can also be output on the printer, you can also communicate with the PC.

Applications roughness are

Applications roughness are: one, insert ball bearing, mainly metal manufacturing. The initial roughness generated is to detect the surface roughness of machined parts and raw. Especially in comparison stylus roughness measuring instrument for the detection of relatively hard texture of the metal surface. Such as: automotive spare parts processing and manufacturing, machinery parts processing and manufacturing, and so on. The processing and manufacturing industries as long as it comes to the workpiece surface quality, roughness tester for testing applications is essential. Shanghai full of love Feng Precision Instrument Co., Ltd. is a professional agent in Japan MITUTOYO Mitutoyo gages and measuring instruments and gauges SK Japan and other professional firms. Second, the non-metal processing and manufacturing, with the progress and development of technology, more and more new material applied to the processing technology, such as ceramics, plastics, polyethylene, etc., are some of the bearing is to use a special ceramic materials processing and production , as well as valves and other is the use made ​​of polyethylene material processing. These materials are hard, some applications can replace metal material of the workpiece, in the production process also requires the detection of surface roughness. Three, with the roughness of the technology and features continue to strengthen and improve, as well as in-depth promotion and application, more and more industries were found to be demand for roughness testing, except machinery manufacturing, the electricity, telecommunications, electronics, , such as the production process also need to assess the roughness on the switch coupling, integrated circuits and semiconductors, and even stationery used in people's lives, tableware, tooth surface roughness of the surface to be used in human testing.

Roughness tester called many names surface roughness tester

Roughness tester called many names surface roughness tester, surface finish instrument, surface roughness tester, roughness tester, roughness tester, roughness tester. It has high accuracy, wide measuring range, easy to operate, easy to carry, job stability and other characteristics, can be widely used in a variety of metal detection and processing of non-metallic surface, the instrument is a sensor host integration pocket instruments, with handheld, turbocharger bearings is more suitable for use in the production site. Shape with pull aluminum mold design, durable, anti-electromagnetic interference capability significantly, with the current design of the new trend.
