An introduction to the working principle of the Fog cannon machine. The mist cannon machine uses the principle that dust can be coalesced and increased by bonding with water. Let fine dust pass through the interaction of equal diameter water droplets to reduce the tension on the water surface. Dust particles and water mist gather into clusters and then sink to the ground under the action of gravity. When the mist cannon machine particles on the construction site are close to the dust particles, the dust control effect is better. The fog cannon machine at the construction site is pressurized by a high-pressure pump, and high-pressure water with a certain pressure flows through the high-pressure atomizing nozzle to produce mist-like water. The diameter is similar to the diameter of dust particles. The water mist is then sent to the dust-raising area through a high-power fan, so that the water mist and dust particles are rapidly absorbed and condensed. It settles under its own gravity to achieve the purpose of dust suppression. The dust suppression cannon also has the functions of humidifying and cooling.

The working principle of the fog cannon machine:

The mist cannon machine uses a high-pressure device to atomize the water to make the water molecules the same size as the water mist and dust particles, and then use a high-power fan to blow the air. The machine has strong wind, large area and dust-proof air. The water mist particles come into contact with condensate and sediment, and then reach to prevent dust and purify the air. The environment in which large-scale environmental protection dust-reducing fog guns are used is very important. The air inlet has been discharged from the fiber dust. The equipment is working, if the equipment is running slowly. Ensure that the equipment motor has sufficient smoothness during operation. Check the strength of the equipment parts frequently, and deal with any abnormalities in time to avoid accidents. The connection of the water pipe must be tight to avoid leakage and waste of water.

Everyone knows that saving sandblasting machine abrasives is closely related to the success of production. To make the fastest efficiency and the lowest abrasive loss, it is necessary to know the data quality and specific and accurate data of the user’s products. Only by knowing the enemy and ourselves can we make the best effect.

• 

• 

1. The burr is brittle

The sandblasting machine uses the low-temperature freezing effect of liquid nitrogen to embrittle the rubber and plastic alloy materials. At this moment, the burr is embrittled before the product. In the time difference between the burr and the product without embrittlement, a high-speed eruption Macromolecule particles hit the product burrs to remove high-quality burrs from rubber-plastic alloy products and aluminum and zinc alloy products.

2. Dust collector

The sand blaster machine is adjusted to the best position before use. The sandblasting machine is a kind of machine that uses compressed air as the power to form a high-speed eruption beam to spray the spray material to the surface of the workpiece to be processed at a high speed, so that the mechanical properties of the surface of the workpiece are changed. The sandblasting machine completes the full active sandblasting through the electrical control system, which can actively adjust the sandblasting viewpoint, sandblasting time, sandblasting interval, back-blowing time, spray gun movement, workbench speed, etc. Clear the filter cartridge of the dust collector on time, dump the waste sand inside in time, and minimize the amount of abrasive used.

3. Spray gun

Before using the mobile sandblasting equipment, first check whether there is any wear (a fundamental type of component failure) in the spray gun. Once the sand nozzle is inspected. The nozzles and other places are worn, so they must be replaced in time to indirectly avoid the waste of abrasives.

4. Sand pipe

Whether the sand pipe is straight or not is a necessary work for inspection before the water sandblasting machine works. If it is folded, it will definitely waste the amount of frosting.

• 

5. Separator

It is the most important part of saving abrasives. Before choosing to buy a portable shotblasting machine, you’d better inform the manufacturer of the types of abrasives accurately before the process is determined, so that the sandblasting machine manufacturer can well integrate your needs when designing. The requirements are regulated to achieve accurate control. The sandblasting machine uses the low-temperature freezing effect of liquid nitrogen to embrittle the rubber and plastic alloy materials. At this moment, the burr is embrittled before the product. In the time difference between the burr and the product without embrittlement, a high-speed eruption Macromolecule particles hit the product burrs to remove high-quality burrs from rubber-plastic alloy products and aluminum and zinc alloy products. Abrasives will naturally reduce the application measure.

Due to the impact and cutting action of the abrasive on the surface of the workpiece, the sandblasting machine can obtain a certain degree of cleanliness and different roughness on the surface of the workpiece, and improve the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece and increasing it The adhesion between the coating and the coating prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating, removing impurities, variegated colors and oxide layers on the surface, and at the same time coarsening the surface of the medium to eliminate residual stress on the workpiece And improve the surface hardness of the substrate.

Sandblasting machine is a method of using compressed air to blow out the quartz sand at high speed to clean the surface of the part. It is also called sand blowing in the factory, which not only removes rust, but also removes oil incidentally, which is very useful for painting. It is often used to remove rust on the surface of parts; to modify the surface of parts (the small wet sandblasting machine sold in the market is for this purpose, the sand is usually corundum, and the medium is water); in the steel structure, the application of high-strength bolts for connection is a relatively advanced Because the high-strength connection uses the friction between the bonding surfaces to transmit force, the quality of the bonding surface is very high. At this time, sandblasting must be used to treat the bonding surface.

The sandblasting machine is used for complex shapes, easy to remove rust by hand, low efficiency, poor site environment, and uneven rust removal. The general sandblasting machine has various specifications of sandblasting guns, as long as it is not a particularly small box, you can put the gun in to clean it.

In recent years, with the continuous improvement of environmental protection work requirements, dust removal equipment is widely used in greening, buildings, factories and mines, such as dust suppression cannon, dust control water truck, etc. The operating procedures of the fog cannon machine are very strict, especially in use, with a series of preventive measures.

The dust cannon machine converts liquid water into mist to achieve spray dust removal. Therefore, the role of the water pump in mist cannon operation is self-evident, and the size of the water pressure has a greater impact on the spray effect of the mist cannon. So, when using the fog cannon, how to adjust the spray pressure of the fog cannon? First of all, we need to know that the water pump of the fog gun is usually a plunger pump and a centrifugal pump. The rotation of the centrifugal pump impeller generates centrifugal force. The liquid in the impeller channel is thrown to the surroundings and flows into the pump casing under the action of centrifugal force. The pump body cannot adjust the water spray pressure, and can only be adjusted through peripheral settings. The plunger pump uses the reciprocating movement of the plunger to change the volume of the pump cavity. So as to achieve the purpose of sucking out the liquid.

• 

• 

There are several aspects to adjust the water pressure of mist cannon plunger pump

1. Close the pump outlet valve, loosen the pressure fixing nut, loosen the pressure adjustment knob, and then pull the pressure adjustment handle to the top.

2. Start the water pump to maintain normal operation, and then press the pressure adjustment handle to the end. Adjust the pressure adjustment knob to keep the pressure at 1.5~3.5MPa. The factory adjustment is 2.5MPa. After adjustment, tighten the pressure fixing nut.

3. Open the outlet valve of the water pump for spraying. It should be noted that the current of the metering pump cannot exceed the rated current of the motor, otherwise the water pressure needs to be reduced before operation.

Many friends often encounter various problems when using mist cannon. I will share with you today. What are the reasons for the noise of the mist cannon?

1. The base of mist cannon is unstable. When the fan works, it produces a lot of noise due to unbalanced forces. At this point, it is necessary to fix the base in time, change the corresponding position or fill the gasket below to maintain the balance of the fog gun.

2. The machine parts are damaged. In this situation, it is necessary to immediately cut off the power supply, turn off the machine, check the system, and replace the damaged parts.

3. The fan speed is too high or the fan rotation direction is wrong. This is because the manufacturer has made an error during the setting, and it should be adjusted according to the manual in time after discovery, otherwise, over time, the machine will be damaged.

4. Foreign matter entering the fan will cause the fog cannon machine to operate unevenly. This situation is usually more common in construction sites or sand quarries and other centers. Because of the large environmental dust particles in these sites, attention should be paid to timely removal of surrounding foreign objects.

• 

• 

In short, in the operation of the fog cannon, it is necessary to always pay attention to the operation of the machine, and to maintain the machine regularly. Before use, pay attention to the installation environment of the fog cannon, keep the surrounding environment dry, and clean the appearance of the motor regularly to ensure The air inlet is not affected by dust particles.

• 

When the fog cannon is connected to the power and water source, you also need to pay attention to the following points:

1. The dust cannon machine adopts the industrial frequency power supply provided by the generator set (also can be connected to the main power supply), the rated working voltage of the motor is 380V, and the output voltage of the generator set is 400V, 50 Hz.

2. When the fog gun machine uses a three-phase 380V power supply, before connecting the fog gun electric control box, the control switch must be installed, and the power cord must be connected to the equipment electric control box.

• 

3. When connecting the power cord, first disconnect the power switch on the front of the electric control box, and then turn it to the OFF position. After the test confirms that the power is cut off, the wiring operation can be performed.

4. When using the three-phase five-wire system, when selecting the power cord, the wire diameter should be determined according to the total power specified in the product technical parameters to ensure that the power cord has sufficient load capacity.

5. When connecting the water source, set a special spray valve. After the semi-working valve, the pipeline will be directly connected to the water inlet of the fog cannon and the water outlet of the water tank.
