LBP100 plasma spraying equipment is a novel plasma spraying system. It uses a mass flow controller and a new generation of inverter power supply controlled by optical fiber as the core configuration system and is one of the most popular plasma spraying equipment in the world at present. Plasma spraying is a process of material surface strengthening and surface modification, which can make the substrate surface have the properties of wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, wear reduction and sealing. The basic principle of plasma spraying technology is to use the plasma arc driven by direct current as the heat source to heat materials such as ceramics, alloys and metals to the molten or semi-molten state and then spray them at high speed onto the surface of the pretreated workpiece to form a firmly attached surface layer. Plasma spraying is also used in the medical field. A coating of tens of micrometers is sprayed on the surface of artificial bones to strengthen the artificial bones and enhance their affinity. The LBP100 spraying system is a spraying equipment developed on the premise of introducing, digesting and absorbing advanced foreign equipment and technology and has many remarkable characteristics compared with other plasma spraying equipment.
The use of industrial robots can improve the efficiency of coating processing and save coating costs. Compared with traditional single-axis or two-axis robots, the six-axis robot can be programmed to have higher spraying efficiency, which can reduce the dispersion of the coating and greatly save consumables.
The work of the robotic arm is controlled by a computer. The spraying part can be programmed in advance to achieve fine control, improve spraying efficiency, reduce overspraying, and avoid waste.
Spraying industrial robots improve the spraying quality of workpiece spraying. Through the manipulator can realize the spraying coverage of various angles, the adjustment of the spraying distance, different workpieces, different materials, different coating thickness, can be adjusted by the manipulator spraying distance, spraying residence time, spraying angle, so as to achieve high-quality coating of coating.
The bed adopts a honeycomb structure and is welded as a whole; The beam adopts the inner honeycomb structure, and the outer wall of the whole plate is bent and formed by the overall welding process; After stress relief annealing, it is processed for rough machining; After the roughing is completed, the vibration aging treatment is completed, and the semi-finishing and finishing processes are finally completed. Therefore, the bed and beam structure have good rigidity and high precision, which completely eliminates the welding stress caused by welding and permanently does not change shape. The honeycomb funnel dust removal system, the lower end of the relative sealing layout, effectively removes a large amount of dust generated during spraying; It provides a good working space for personnel.
In the process of thermal spraying, high noise and a large amount of dust are generated, and if the noise and dust pollution is not prevented, it will cause harm to the physical and mental health of the operator, and also pollute the environment. Therefore, noise control, ventilation and dust removal are indispensable components of the entire thermal spraying process.
Our company has obtained great experience and progress in technology for the main equipment of thermal spraying of many domestic enterprises, such as noise control, ventilation and dust removal, and automatic mechanical equipment, and is the supplier with the largest amount of thermal spraying in China.
Before the nickel mesh is sprayed, the sandblasting roughening is carried out first, and there are sand particles floating dust on the surface after roughening, and then through the integrated cleaning and spraying system, the surface is cleaned and cleaned, and then enters the state to be sprayed, and the nickel mesh after sandblasting can effectively improve the adhesion of the coating, and the sandblasting system is installed next to the spraying room, which is convenient to quickly connect with the spraying process and improve the overall spraying efficiency.
This equipment consists of truss feeding system, sandblasting chamber body, workpiece motion system, spray gun system, spray gun motion system, abrasive recovery system, abrasive sorting system, abrasive storage system, dust removal system, electrical control system.
In order to capture and purify the free dust during the operation of the spraying room, and the spraying heat is quickly dissipated, the spraying room has set up a ventilation and dust removal system.
Compressed air is required for spraying and for use in the dust removal system, so a stable compressed air supply system is required. We use Taiwan Youqiao brand air compressor system, with an exhaust volume of more than 12 cubic meters per minute.
Equipped with a refrigeration dryer and a three-stage oil-water separation filtration system, the compressed air output is removed from the compressed air through the front filter and dryer, and then through the back filter to obtain clean air.
Because the spraying needs to be clamped by the tooling, it is necessary to manually complete the combination of the spraying nickel mesh tooling, place it on the transport trolley and push it to the loading station with spraying manipulator.
The system is a turnkey project, involving more equipment, through the centralized control system, can help customers easily control the various facilities of the spraying system, the system is the core of the whole system, the operation of the auxiliary system, safety interlocking, alarm information are centrally processed by the system, the system includes control, monitoring, alarm, collection, recording, all kinds of data complete.
It helps users to achieve efficient spraying operations, ensure the quality of coatings, and also improve the efficiency of use, and the safety of operators is also guaranteed.
The plasma spraying and supersonic spraying system supplies gas to the equipment inside, which has passed the air tightness test, is safe and reliable, and is equipped with a safety cabinet for flammable cylinders, and the combustible gas is stored separately from other gases.
Parameters:
1. Flammable gas safety cabinet: 900mm*450mm*1900mm (length, width and height)
2. Nitrogen manifold discharge and pressure reducing device.
3. Argon decompression device.
4. Hydrogen decompression device.
5. Hydrogen leakage alarm device.
All kinds of cables, communication cables, air compressor pipes, cooling gas pipes, trunking, threading pipes, pipe fittings, auxiliary hardware and other materials in the system. All adopt national standard quality to ensure the quality of electrical connections.
Roll into a cylinder with steel plate, supplemented by the color anti-corrosion specified by the user, the flow rate in the pipe is generally calculated according to 12~18m/s, the length of the pipe, the elbow is adapted to local conditions, according to the layout of the on-site equipment, in accordance with the requirements of the Ministry of Environment and Ecology of the People's Republic of China, the exhaust pipe of the industrial plant shall not be less than 15 meters high, the design sampling platform, the air duct starts from the spraying room, first connects the spraying room and the dust collector, and then uses a soft connection to connect the dust collector and the fan, and then extends to a height of 15 meters after installing the silencer from the fan outlet.
