Power Industry - Solve the power plant overhaul problem

 Power industry is a modern basic industry, power generation and power supply equipment variety, large quantity, high complexity. Air leakage, water leakage, oil leakage, coal leakage, ash leakage, smoke leakage, air leakage, wear, corrosion and other problems have been plaguing the safety and civilized production of power enterprises. As we all know, for more than 10 years, Fengshen new materials has been supplying Fengshen series products for the power industry. Fengshen New Materials provides cost-effective solutions for many aspects of the power production process. Fengshen new materials for the characteristics of the power industry to provide a complete range of repair, maintenance products and perfect solutions, the following is the application of Fengshen products.

Combustion system solutions

Conveyor belt: coal conveyor belt of thermal power plant, which is partially damaged or broken due to long-term use. The use of high-performance rubber repair agent, rubber repair agent and rubber adhesive for repair, the strength can reach the strength of hot vulcanization, and the construction is convenient, no special equipment is required compared with hot vulcanization, the operation time is short compared with traditional cold vulcanization: high peel strength.

Conveyor belt

The solution:

Trapezoidal steps are made according to the different layers of the conveyor belt. The lap of each step is 16°, and the lap width is 1.2 ~ 1.5 times the width of the conveyor belt. The adhesive surface is roughened with a wire wheel, and the residual rubber on the surface must be removed. Use cleaning agent to clean, after volatilization can apply rubber repair agent, laminated, with high-performance rubber repair agent caulking. The screw locking sealant used for fastening bolts of belt conveyor motor anchor can effectively prevent the anchor vibration caused by long-term vibration impact. The cylindrical parts holding agent used in the bearing position of the motor end cover can solve the problem of running the outer ring and running the inner ring.

Pulverized coal transportation pipeline: power plant combustion system to transport pulverized coal transportation pipeline is mostly Q235 material, raw coal after grinding into pulverized coal like a fluid flow in the pipe, through the coal pipeline to the furnace. After a period of use, the inner wall of the pipeline is seriously eroded and worn by pulverized coal particles, and the wall thickness is thinned. At the bend of the pipe, the pipe wall will even be worn through by pulverized coal, which will pollute the environment and reduce the efficiency. In order to improve the wear resistance, the selection of appropriate sealing structural adhesive ceramic pieces can avoid pipe wear well, and play a role in protecting the pipe and extending the service life.

Separator: The cyclone separator in the power plant has a lot of abrasive wear, and the special parts are worn into channels or perforations by coal powder. The structural adhesive ceramic sheet is used to wear and prolong the service life of the separator.

Coal mill: The medium speed cone of the power plant is seriously worn under the erosion of high velocity coal particles. Use structural adhesive to stick wear-resistant ceramic sheet, equipment life of 2 ~ 3 years. The leakage oil of the coupling surface of the reducer housing of the coal mill can be solved by selecting the anaerobe plane sealant. For the rolling bearings of various reducer boxes and the inner and outer rings of motor end cover bearings in the ball mill, the sealing cylinder parts retaining agent can be used to restore the accuracy and improve the reliability of operation.

Fan motor: power plant fan motor shaft "rinse ring", seriously affect the normal use of equipment, traditional methods such as electroplating, brush plating, can not resume operation in a short time, the use of cylindrical parts holding agent, bearing holding, fast, but also save valuable time and a lot of costs.

Power plant pulverized coal blower:
The anti-grinding coating of the impeller of the pulverized coal blower in the power plant has been carried out by the wind for a long time, and the blades wear seriously, which can not work normally for about half a year. Selecting wear-resistant repair agent to make anti-wear coating in blade and surrounding cavity can prolong impeller life.

Soda water system solutions

Leak-proof is key
Steam turbine low-pressure cylinder facade leakage repair: before leaving the factory, the low-pressure cylinder is well sealed, and in the long-term operation, due to the influence of cold thermal expansion stress, the sealing gasket has a certain residual compression deformation, resulting in leakage, the selection of high temperature repair agent and glass fiber reinforcement belt can avoid leakage.

Professional chemical sealing materials, to provide you with appropriate sealing

Condenser end plate corrosion repair: due to scale caused by large-scale rust, blockage, damage. Brush the working surface with a corrosion-resistant coating to create a protective layer. Corrosion occurs at the expanded pipe, resulting in internal leakage. Electrochemical corrosion occurs at the connection because the copper pipe and the tube plate are metals of different materials, which needs to be repaired. The use of sealing multi-functional cleaning agent + corrosion resistant coating leakage, with multi-functional cleaning agent to remove dirt, corrosion resistant coating adhesive and metal high bonding strength to prevent further deterioration of corrosion, and corrosion reoccurrence.

Oil pipeline: the oil level emergency repair agent can repair the oil pipeline of the power plant with oil, solve the problem of oil leakage in the power plant, and the welding seam of the oil blocked pipeline, sand hole, oil leakage and so on. Professional chemical sealing materials for power plant cost savings to provide protection.

Circulating water pump:
During the use of circulating pump, the size of pump shell and impeller is reduced or the honeycomb surface is caused by erosion, cavitation, wear and corrosion. Serious perforation, replacement and maintenance is very frequent, the use of wear-resistant coating to repair the circulating pump, not only can save the failed parts, but also extend the service life of the equipment. Can be on-site operation, do not disassemble and replace the water wheel, to replace welding, saving work quickly.

Transformer: All kinds of transformer radiator and tank interface flange, weld and tank shell sand hole, shell and base or top cover connection flange, porcelain sleeve riser flange, all kinds of wire plugging, due to the limitations of the traditional sealing method, transformer oil will often leak, directly affect the safety of the transformer work, affect the appearance. The selection of oil level emergency repair agent and emergency repair agent can plug the transformer belt oil without stopping.

Generator: The large protection ring of the motor causes electrical erosion due to leakage. A large pit with a diameter of φ80mm and a depth of 8.4mm was burned, which is prohibited. At room temperature, the use of high temperature repair agents and copying wood for maintenance will not have a thermal effect on the equipment, and play a role in restoring the normal operation of the motor.

Hydraulic coupler:When assembling after service, seal with 1515 anaerobic flat sealant. The sealing pressure can reach 30MPa. Compared with the traditional sealing method, it is resistant to leakage, running, bubbling, dripping, leakage and seepage.
