The 4KW water blasting machine (MG-SP4KP) uses blasting abrasives (such as brown corundum, white corundum, quartz sand, etc.) and liquid (water) as the medium, and uses compressed air (air compressor) as the power. A sand blasting device for spray cleaning of non-metallic workpiece surfaces.
Scope of application: It is widely used in machinery, locks, electronic clocks, glasses, hardware tools, molds, glass, ceramics, crafts, medical equipment and other industries.It can remove casting scale, forging, stamping, welding, heat treatment and machined parts. , Residue and burr, three-dimensional glass carving, spray painting and other processes. The surface of decorative objects such as clocks and glasses has the effect of imitating the alloy. Is currently the ideal surface cleaning and refurbishing equipment.
Our company's main environmental protection blasting equipment are: wet blasting machine, negative pressure water blasting machine, water blasting equipment, environmental protection blasting machine, derusting blasting machine, stainless steel blasting machine, automatic blasting machine.
One: The sandblasting and rust removing device supporting mechanical equipment is composed of an air compressor, an air storage tank, an oil-water separator, a sandblasting machine, and a high-pressure sandblasting hose. The specific matching is as follows:
1: Equipped with a compressor of 3 m3 / min;
2: One gas storage tank;
3: air filter (oil-water separator) 3; 4
4: a 0.3 cubic blasting machine.
5: Several high-pressure blasting hoses and spray guns.
Two: Sandblasting machinery and equipment supporting flow chart: air compressor-high pressure oil pipe-gas storage tank-high pressure oil pipe-sand blasting machine-sand blasting pipe spray gun
Three blasting operation process parameters:
1: 22kw air compressor should be used for compressed gas.
2: The purity of compressed air can be tested by the following methods: Spray compressed air on a piece of white paper for 20 to 30 seconds, leaving no oil stains or moisture marks on the paper. The compressed air is considered clean and can be used for sandblasting Descaling.
3: Nozzle diameter: 8-10mm should be selected.
4: Spraying distance: 100 ~ 200mm should be selected.
5: Spray angle: 30 ~ 75 degrees should be selected.
Four: Sandblasting operation method
1 Connect the sand blasting device and prepare the materials. Start the air compressor, adjust the pressure at 0.6-0.7Mpa, and test the compressed air flow at the nozzle with a clean white cloth to ensure no oil and moisture.
2 The operator wears protective clothing, adjusts the ventilation, turns on the switch after the signal is turned on, sends air and sand, and starts spraying. The upper and lower surfaces of the workpiece are sequentially performed from the inside to the outside.
3 Sand blasting should be evenly distributed, not too fast, so as to avoid leakage and affect quality. Welds, corners and scales should be sprayed intact (welds should be flat, free of pinching, no welding knobs, and convexity should be less than 3 mm).
4 The compressed air used for sandblasting must be processed by a cooling device and an oil-water separator to ensure that the compressed air is dry and oil-free. The oil-water separator must be cleaned regularly.
5 During the blasting, ensure that the compressed air is dry and free of moisture and oil. The air filter should be replaced regularly. The air buffer tank and oil-water separator should be drained of fluid.
MG-SP4KP water blasting machine features: sturdy and durable, will not corrode
① The body is made of glass fiber reinforced plastic, which is durable and will not corrode.
② Using a new type of non-powered air control switch to control sand pump and compressed air at the same time, the operation is simple, safe and reliable;
③ The sand pump is reasonably designed, and the uniform stirring makes the surface of the sand blasted product uniform and beautiful, easy to start, long service life, and convenient maintenance.
④ New and novel design, suitable for blast processing of small and medium-sized precision workpieces.
⑤ The parts are safe and reliable, with few wearing parts.
⑥ It is recommended to use thin glass beads!
Application of this machine:
① Suitable for liquid blasting
② Clean up the oxide scale on the surface of heat treated parts, welding parts, castings, forgings, etc., and the cleaning quality can reach Sa3 level
③ Changing the stress state of the surface of the workpiece can improve the wear resistance and fatigue strength of the part
④Clear micro-burrs and surface residues on machined parts
⑤ The surface pre-treatment of the workpiece before spray coating and electroplating can obtain an active surface and improve the adhesion of the spray plating layer
⑥ Finishing finishing of parts with high precision, low Ra value, and complex shapes that are difficult to complete by other processing methods
⑦Can increase or decrease the surface roughness Ra value within a certain range
⑧Improve the lubricating conditions of the sports matching parts, can reduce the movement noise of the sports matching parts, etc .; It can also be used for the refurbishment of old parts.
The difference between a wet blasting machine and a dry blasting machine is that the wet blasting machine puts sand and abrasive in water, mixes the water and sand, and uses high-pressure gas to spray quickly to the processed object through the spray gun nozzle To achieve the effect of cleaning the surface of the object. Dry blasting machine cannot mix sand and water. Wet blasting machine is much more efficient than dry blasting machine, and the consumption of sand material is much less. It can also improve the cleanliness and finish of the surface of the processed object, and improve the surface of the processed object. Strength and adhesion, and no pollution to the environment, very environmentally friendly; wet blasting machine is easy to install, no need to work in a separate workshop, can be processed directly on the production line.
