Characteristics and advantages of HV-80-JP supersonic flame spraying system

1, Solid cabinet design, fuel flow control area, pressure display area, electronic control area are modular layout, panel clear and easy to operate.
2. All imported valves, pressure switches, flow switches and sensors from Europe and America are of the same quality as those from Europe and America
3, The use of Japanese mitsubishi high-performance PLC control, after ignition automatically maintain oxygen and fuel, carrier gas flow output.
4. All the internal fuel, oxygen, carrier gas and cooling water connected on the equipment have the detection function to ensure that all preparation processes can be fully tested before ignition.
5. Monitor the running status of the equipment in real time. Once any part is found to be operating beyond the safe range, the whole system will stop sharply, send an alarm and provide fault information.
6. The equipment starts and stops automatically under the control of PLC, which reduces the possibility of operator's misoperation.
7. Communication interface is set up inside the equipment to control the operation of peripheral devices.
8. Signal shielding measures are adopted to protect peripheral devices from electromagnetic interference during high frequency arc ignition.
 

 

In order to obtain higher energy efficiency and greater thrust, the turbine inlet temperature of aero engines and heavy-duty gas turbines has reached more than 1600 degrees. The improvement of material performance and structural design alone can no longer meet the rapid development of aeroengine and gas turbine industries. The high-temperature protective coating technology is already indispensable. The fourth-generation high-temperature protective coating-zirconia thermal barrier coating has been applied to some high-temperature parts of aeroengines (guide blades, flame tubes, heat shields, etc.), and has achieved good results.

The steam turbine is one of the three main engines of thermal power plants-boilers, steam turbines, and generators. The main body is composed of a rotating part and a fixed part. The rotating part is composed of impeller, main shaft, coupling and blades; the fixed part is composed of nozzles, cylinders, steam seals, partitions, fasteners, bearings, etc.
In the process of thermal power generation, it is the steam turbine that converts thermal energy into mechanical energy. In the process of power generation, the efficiency of the power plant and the safety of the unit will be affected by the steam turbine. When the steam turbine generator set is in operation, after the steam enters the steam turbine, various impurities are carried by the steam into the steam turbine, which will form fouling and corrosion. In particular, the final stage blades operate under extremely harsh conditions and bear the combined effects of high temperature, high pressure, centrifugal force, steam force, steam exciting force, corrosion and vibration, and water droplet erosion in the wet steam zone. The damage is even more significant. And with the increase of load, due to the impurities carried by superheated steam, more and more serious corrosion, salt accumulation and generation of steam turbine blades, the safe operation and efficiency of the unit are more and more significantly affected.
When the steam turbine is started, if the quality of the superheated steam passed in does not meet the required standard, if it is put into operation at this time, the salt will be dissolved and carried into the steam turbine through the steam, and gradually deposited on the steam turbine blades at all levels, which will increase the weight of the blades. Steam turbine output has an impact; unbalanced salt accumulation can also cause uneven weight, which is likely to cause vibration. The corrosion of blades under fouling will seriously damage the material and strength of the blades, and it is easy to cause vicious accidents when the steam turbine is running.
The use of supersonic spraying cermet coating can effectively improve the service life of steam turbine blades. Use repair welding, sand blasting, spray transition layer, spray coating, coating sealing agent, blade protection technology methods. The combination of the coating and the surface of the blade has high strength, no peeling, and the coating life can reach more than four years. At the same time, it also reduces the use cost of 1/3 to 1/6. It is suitable for blades and low-temperature steam in the wet steam zone. The last stage blades operating under load conditions can be applied to both new and old blades.
