Product Description ComponentCharacteristicParameterHV-8000Control cabinet1,Imported core accessories and mass flow-meter, full closed loop system, high-performance PLC control2,Rugged design, Europe and the United States imported valves, pressure switches, flow switches, sensors,the quality is like Europe and the United States equipment.3,Touch screen operation, intelligent automatic operation;4,Process parameters on the touch screen panel at a glance;5,One key operation, can realize the spraying process automation and real-time detection, 7 alarm prompt, can respond to the system fault immediately.1,Program control: full closed-loop PLC control2.Interface control: 12-inch touch screen3.Flow control: mass flow controller4. Input power: 5000W5. Kerosene pressure: 1.2Mpa6. Kerosene flow: 0~60L/h7. Oxygen pressure: 1.6mpa8. Oxygen flow: 0~60m3/h9. Carrier gas pressure: 0.1~0.3Mpa10. Carrier gas flow: 3~30L/min11. Main parts origin: Germany, America, Japan, Italy ComponentCharacteristicParameterD-3000Powder feederThe powder feeder is a high precision powder feeding mechanism which outputs via metering panel, uses patented feeding valve, with powder evenly output, having higher precision compared with the conveying modes of scraper type, screw and vibration, etc.; Adopting small-flow nitrogen or argon gas as feeding gas, which, together with powder that arrives at powder outlet with rotation of feeding panel on the bottom, enters the spray gun, to save more gas than traditional mesohigh powder feeder. Compared with the traditional double barrel type powder feeder, the metering disc type powder feeder is more fine and the powder particle size range is wider.Feeding mode:metering panel2. Cleaning method: barrel body turnover3. Powder drying function: built-in heater4. Powder cylinder mode: single cylinder type5, self-cleaning function: yes6,Volume of powder storing barrel:3.5L7,Feeding gas: Nitrogen,argon8,Pressure of feeding gas: 0.15-0.3Mpa9,The carrier gas flow rate:0~15L/min10Feeding speed:0~220g/min11Feeding precision:±1%12,Powder size :5~150μm Characteristics and advantages of HV-80-JP supersonic flame spraying system1, 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 America3, 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, and heavy duty gas turbine engine turbine inlet temperature is as high as 1600 degrees above, only on the improvement of the performance of the materials and the improvement of structure design, has been unable to meet the rapid development of aviation engine and gas turbine industry needs, high temperature protective coating technology is essential. Zirconia thermal barrier coating, the fourth generation of high temperature protective coating, has been applied in some high temperature components of aeroengines (guide vane, flame tube, heat insulation screen, etc.), and achieved good results.Steam turbine is one of the three main engines of thermal power plant -- boiler, steam turbine and generator. The body is composed of rotating part and fixed part. The rotating part is composed of impeller, spindle, coupling and blade; The fixed part consists of nozzle, cylinder, steam seal, baffle plate, fastener, bearing and so on.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 and safety of the power plant will be affected by the steam turbine. In the operation of the turbine generator set, after the steam enters the steam turbine, as a result of various impurities carried by the steam into the steam turbine, scaling corrosion will be formed. In particular, the final blade operates under extremely harsh conditions, bearing the joint action of high temperature, high pressure, centrifugal force, steam action, steam excitation force, corrosion and vibration, as well as water droplet erosion in wet steam area. The damage is even more pronounced. And with the increase of the load, due to the superheated steam carrying impurities, more and more serious corrosion, salt accumulation of steam turbine blades, the safe operation and efficiency of the unit is more and more significantly affected.When the steam turbine starts, if the quality of the superheated steam through the inlet does not meet the required standard, if 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, so that the weight of the blade increases, affecting the output of the steam turbine; Salt accumulation imbalance will also cause uneven weight, which is likely to cause vibration. The corrosion of blades under scaling will seriously damage the material and strength of blades, which is easy to cause malignant accidents in the operation of steam turbines.The service life of turbine blade can be improved by supersonic spraying cermet coating. Using repair welding, sandblasting, spraying transition layer, spraying layer, coating sealing agent, blade protection process. With the combination of coating and blade surface, high strength, no shedding, coating life can reach more than four years, but also reduce the use cost of 1/3 to 1/6, suitable for the blade in wet steam area and the last stage blade under low load conditions, new and old blades can be applied.
