The linear motion ball bearing has a layout in which an adherer is installed in the outer ring; the adherer is equipped with a plurality of steel balls; and the infinite circulation motion is performed; the two ends of the holder are fixed by the inner spring retaining ring; the straight line in each steel ball is subjected to the force operation The track side is provided with a notched window. This is to make the loaded steel ball and the shaft roll and touch. It is relatively moved with a very low friction coefficient; therefore, the linear motion ball bearing is the most suitable for mechanical equipment, automation equipment, energy-saving equipment, etc. Bearings. Linear motion bearings; currently used more and more widely in electronics, machinery, instruments, robots, machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, CNC machine tools, automobiles, etc. Among the industries. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The advantages of using linear motion ball bearings:
1. Because the active touch can make the starting friction resistance and the dynamic friction resistance extremely extreme. The silky tip of the silk is more beautiful.
2. The load is increased; but the friction coefficient is not sensitive; therefore, under heavy load; the friction coefficient is extremely. (3) Page ã¦è¯’ 3 æ§æ´Œè±¢ æ§æ´Œè±¢ æ§æ´Œè±¢ æ§æ´Œè±¢ æ§æ´Œè±¢ 没 褂 褂 褂 褂 倜ã¦è¯’ 倜ã¦è¯’ 倜ã¦è¯’
3. Linear motion bearings have good interchangeability; the device is easy to use and time-saving; and the mechanical layout is novel; small; light weight.
4. Saving oil supply procedures; reaching the intention of simplifying smooth protection.
5. Bearings with oil seals on both sides are also suitable for places with more dust or simple intrusion of foreign matter.

Maglev centrifugal blower is a new type of high efficiency, energy saving and environment friendly blower formed by integrating magnetic suspension bearing technology and high speed motor technology into a traditional blower. Magnetic bearings are used to generate a magnetic field by means of an electric current and a magnetic field Generate suction to achieve the suspension shaft.High speed motor through the frequency conversion power supply to generate a frequency controllable alternating current input stator magnetic field to produce an alternating drive high-speed rotation shaft, that is, synchronous permanent magnet motor with the shaft together for high-speed rotation of the blower The impeller drives the air to enter from the air inlet of the volute and the air becomes a gas with a certain flow rate and pressure under the guidance and pressurization of the volute and finally bulges out from the air outlet of the volute.
What is the difference between Magnetic suspension centrifugal blower and air suspension centrifugal blower ?
1, the difference between the two is the use of different bearings, magnetic suspension As the name implies bearing using magnetic bearings, air suspension that uses air suspension bearings. The common denominator is that both types of suspension blowers adopt high-speed direct-coupled motors, frequency-variable speed regulation air volume and non-contact bearing technology, no lubrication system is required, no secondary pollution to the environment, high efficiency, low noise, Wide range of adjustment and other advantages.
2, but due to the special domestic air environment, air suspension bearings in the domestic environment, the higher the failure rate of operation, it is proposed to use resistant magnetic levitation blower. Here to talk about magnetic levitation, foreign companies engaged in the development and manufacture of magnetic bearings MECOS Switzerland, Switzerland, Canada REVOLVE company, Germany SEVNZ company, South Korea TURBORMAX company, the current German SEVNZ magnetic levitation fans and South Korea's TURBORMAX company's products in the international environmental field more Common, higher market share, if used, this should be the first choice. Although the cost of such a device is relatively high at one time, due to the saving in the construction process and the civil construction investment in the blower room and the power consumption and maintenance cost in the operation process, the overall life cycle cost of the entire project is taken into account. Blower with high economic efficiency, the aeration blower is the future development of the environmental protection industry's main direction.
1, according to centrifugal fan performance curve to select the fan. This is one of the most basic and relatively simple method.
2, the use of centrifugal fan performance table to select the fan, this method is the same as the use of pump performance table to select the pump, although simple and convenient, but can not accurately determine the fan unit operating conditions.
3, Centrifugal fan performance selection curve Select fan This is the most commonly used fan selection method. Selection curve is the same series of similar, different impeller diameter of each fan of the total pressure, power, speed and flow relationship.
4, Centrifugal fan dimensionless performance curve selection Fan fan dimensionless performance curve is a non-dimensional performance parameters that represent a variety of models, different numbers of fans. In order to narrow the choice of the first choice of fan speed.
