The HV - 8000 Supersonic Flame Spraying System consists of a main control cabinet, a spray gun, a powder feeder, a chiller, and an oil pump system. As an innovative HVOF system, it showcases outstanding performance in the thermal spraying field. By using aviation - grade kerosene as fuel, leveraging its high calorific value and strong combustion stability, this system has distinguished itself in the international thermal spraying equipment market, emerging as a top - tier kerosene - fueled device, and is highly favored by customers worldwide. Since its market launch, the HV - 8000 has earned extensive acclaim and unanimous recognition from customers due to its consistently excellent performance, and has been rapidly popularized and applied in the thermal spraying industries both at home and abroad.
Analyzing from the working principle aspect, the operation of the HV - 8000 system is sophisticated and intricate. The oxidant oxygen, under the action of the atomizing nozzle, is thoroughly mixed with kerosene through fine atomization to form a homogeneous and combustible gas mixture, which is precisely introduced into the combustion chamber. The ignition system is then activated, instantly igniting the gas mixture, triggering a violent combustion reaction and generating high - temperature and high - pressure gas. Guided by the special structure of the Laval nozzle, this gas further achieves energy concentration and velocity increase, ultimately forming a high - speed and high - energy supersonic flame jet. Simultaneously, the powder feeding system works in close coordination. Relying on the unique low - pressure zone powder feeding technology, it accurately and stably delivers the powder material into the core area of the flame jet. Entrained by the supersonic flame jet, the powder undergoes rapid heating and powerful acceleration processes. It impacts the surface of the workpiece with extremely high kinetic energy, and by virtue of its excellent melting and adhesion properties, it constructs a high - quality coating with a dense structure and superior performance, providing long - term protection and functional enhancement for the workpiece.
In terms of human - computer interaction design, the HV - 8000 equipment demonstrates a high level of user - friendliness. The equipment panel abandons the traditional complex button layout and fully adopts the cutting - edge touch - screen operation mode. The interface integrates eight internationally leading functional modules, covering a full range of functions from basic spraying parameter setting, process flow control, and other common operations to real - time information dynamic display and intelligent fault alarm prompts. The operation logic is highly consistent with user habits. Both experienced professional technicians and beginners in the thermal spraying field can quickly get the hang of it and easily operate the equipment. Moreover, during long - term operation, the equipment always maintains stable and reliable quality performance, ensuring efficient and accurate thermal spraying operations.
Set up a spray painted soundproof room. According to the principle of acoustics, the noise generated during spraying is controlled inside the room to prevent outdoor workers from being contaminated by noise and damaging the nervous system. The sound insulation room is composed of four angle steel columns, wall panels, top plates, upper and lower grooves, corner wrapping, and special sealing components for gaps, which not only ensure the sound insulation and overall rigidity of the room, but also pay special attention to the appearance and thoughtful detail treatment. Each completed project has received unanimous praise and praise from domestic and foreign users.
The structure of the panel group is as follows: the outer wall is made of 2.0mm thick white spray coated steel plate, filled with a damping layer, asbestos board, double-layer 100Kg/m3 high solubility weight sound-absorbing cotton, waterproof and dustproof sound-absorbing film, and the inner wall is made of metal porous sound-absorbing plate (with a punching rate of 25%). The soundproof panel is supported by welded steel frames arranged in a zigzag pattern, which are then pressed into shape. The soundproof panel is smooth and scratch resistant both inside and outside, with a bright and beautiful surface.
The standard W of the soundproof board is 970mm, the thickness is 210mm, and the L can be determined by the required H of the room. The sound insulation board has undergone noise testing (with no gypsum board placed on the tested sample), and the air sound insulation in the frequency range of 125-4000Hz is 42dB (A). At present, the soundproof board added with PDF fiberglass board has a greater sound insulation capacity in practical applications. The soundproof board is assembled with specially made and thickened steel plates, and the gaps are filled with glue to prevent sound leakage;
Multi-layer soundproof panel structure
We have designed the soundproof door for the entry and exit of the workpiece as a stepped sealing structure, which achieves noise reduction through a stepped structure. At the same time, a sealing strip is used on the door for sealing. When the door is opened and closed, the sealing strip plays a sealing role, reducing sound leakage.
Observation windows are installed on soundproof wall panels and doors, using transparent tempered glass. The number of observation windows on soundproof panels is specified by the owner. Air intake and exhaust muffler
To meet the needs of indoor dust extraction and ventilation, the spraying room is equipped with inlet and exhaust silencers to maintain a balanced negative pressure inside the room. As the airflow passes through the muffler, indoor noise is absorbed by the muffler. Prevent noise from spreading outward through the air inlet.
There is a suction box installed in the room that can adjust the air volume and regional wind direction. The L of the suction box is 2 m and it is divided into two areas. The left and right sides can be adjusted with louvers for air volume and wind speed adjustment.
Adjustable suction box
It is used to isolate the noise and dust generated during the sandblasting operation of the workpiece. It has: beautiful and atmospheric purification board facade, steel structure strengthening structure, anti-wear rubber lining board, observation window, double door, single opening work door, dustproof lighting, dust suction port and fresh air intake port.
Sand blasting system
Zhengzhou Lijia ZC series horizontal turntable is a special equipment designed and manufactured for thermal spraying shafts, rollers and ball valve parts, shaped like a lathe, and its function is mainly to load and rotate the parts transversely during the spraying process, so it is called "horizontal turntable". This series of products are customized according to the different loads of the clamped workpiece, and the mechanical structure of the horizontal turntable is reasonably designed, which not only effectively blocks the impact of dust on the transmission part, but also ensures the durability of the equipment due to the use of high-quality materials and component assembly.
