Ceramic bearings are compared with steel bearings:

1.Self-weight is 30% to 40% of steel bearings:It can reduce the centrifugal force of the operation, and the speed is 1.5 times of the steel bearing, the hardness is 1 times of steel, and the wear-resisting and anti-pressure is 5-7 times that of steel.The thermal expansion coefficient is less than 20% of the bearing steel.Friction coefficient is less than 30% of bearing steel, heat resistance, tensile and bending are equivalent to metal.

2.The maximum service life is five times longer than the steel bearing:Under the load, the centrifugal force decreases, the roller load decreases, the friction coefficient is small, reduces the operation temperature rise, reduces the friction, and extends the life of the raceway.

3.High speed ceramic bearing:It has the advantages of small force elasticity, light weight, small friction coefficient, high pressure resistance and cold tolerance.It can be used in the high-speed spindle and high precision equipment of 12000 RPM/min -75000 RPM.

4.High temperature ceramic bearing:Resistance to high temperature 1200 ºC, and good self-lubrication, temperature between 100 ºC to 800 ºC is not caused by temperature difference expansion.It can be used in high temperature equipment such as kiln, steel and smelting.

5.The magnetic:Ceramics are not magnetic, magnetic foreign objects and dust are not adsorbed, low noise and so on.Reduces wear and tear.Application in demagnetization, precision instrument and other equipment.

6.Corrosion resistance:Ceramics have the characteristics of corrosion resistance.Applied to chemical machinery, navigation ships, Marine operating machinery, electroplating equipment, electronic equipment and so on.

7.Electrical insulation:It can be used in insulation equipment.

8.Oil-free self-lubricity: The ceramic material has the characteristics of oil-free self-lubrication, which can prevent the lubrication of oil and grease and overcome the problem that the ordinary bearing cannot realize self-lubrication. Therefore, it can be used in high vacuum environment.

Closed Cooling Tower

Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.

First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.

Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.

Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.

To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
