Low Frequency Slip Ring A slip ring assembly that uses a sliding contact to transmit low frequency signals and energy. A typical slip ring has a cylindrical slip ring and a differential slip ring. The conductive ring of the cylindrical slip ring is further divided into a flat ring and a V -ring. The material of the conductive ring is usually made of copper, brass, coin silver and gold. The brush has a palladium, gold alloy or gold plated wire brush and a copper graphite synthetic brush. If the number of slip rings is large, the cylindrical slip ring is composed of upper and lower sets of brushes and a differential adapter plate (Fig. 1 differential slip ring schematic diagram), but its axial dimension is large, and differential sliding is adopted. The ring can significantly reduce axial size, reducing volume and weight. The differential slip ring is composed of upper and lower sets of brushes and a differential adapter disk. The upper brush rotates with the antenna azimuth, and the lower brush is fixed. The differential adapter plate has two upper and lower contact pieces, and the corresponding contact piece is connected by a wire, and the differential mechanism is used to make the rotation speed 1/2 of the azimuth rotation speed. . When the antenna rotates , the current flowing into each of the lower brushes passes through one or two contact piece circuits on the differential turntable, and flows out from the corresponding upper brush to ensure that the circuit between the fixed portion and the rotating portion is always turned on. The powder worn by the sliding contact slip ring may cause a short circuit between the ring and the ring. Therefore, it should be structurally guaranteed to be easy to clean, usually with a combined structure for on-site repair or replacement of components.
1, strong, thermostable
Because CPVC compares PP-R, PE-X to be firm. Compared with PP, the PE-X tube, under the similar pressure, CPVC may use a smaller caliber to achieve the same water flow, thereby saving material costs and installation time. Compares with other thermoplastic, CPVC has the remarkable mechanical property under the different temperature, is suitable for the bearing the situation, the application temperature may reach as high as 93°C, the life may amount to 50 years.
2, easy installation
The connection method are very similar with PVC. Most commonly used and simple connection method is resolver cementation. Other connection methods are threaded connection, flange connection and electrode connections.
3, non-corrosive oxygen permeability
CPVC have the anti-oxygen, therefore the oxygen seepage from the radiator will not bring metal corrosion.
4, reducing the infiltration of additives
In order to prevent oxidation, some modified plastics needs to increase the massive antioxidant that may be infiltrated into the water supply system ,causing the ill-smelling smell.
5, without the impact of chlorine in water
A lot of polyolefin materials (including PP, PE) may be decomposed with water, while CPVC is not affected by the impact of residual chlorine in water that there is no cracks and leakage.
6, good flame retardancy
CPVC limiting oxygen index is 60, therefore it will not burn in the air. It has the characteristics : misfires the flame decoction,not to increase the fire set,restrict flame spread,low smoke generation. 7, CPVC has excellent chemical resistance to non-polar strong acid and alkali. Commonly used to substitute the metal to process the corrosive material, such as the poor quality of water, acidic material alkaline matter and other peroxide solutions.
8, the low thermal conductivity
CPVC thermal conductivity is only 1.05. heat is not easy to disseminate from the pipeline, heat loss of pipeline is low.
9, bacteria breeding is not easy
CPVC is not influenced by the impact of residual chlorine in water. So it will not result in cracks and leaks. Inner wall of pipe is smooth, not easy to breed bacteria. The research indicated that the breeding of germs in CPVC pipe is far lower than other materials such as copper, steel and other plastic pipe.
10, low thermal expansion
CPVC thermal-expansion coefficient is lower than other plastics. The tube expansion is very small when tube-pass heat, unlike other types of channels (such as PP-RRP) due to the higher temperature caused by heat expansion coefficient that could cause snake bending,the existence safe hidden danger and eyesores.
11, the test of time
none of a thermoplastic material such as CPVC,avoid the maintenance after 40 year hot water system's test, and displays its excellent performance
