What is the reason why the sandblasting machine only sprays sand but does not produce sand?

The reasons why the sandblasting machine only sprays sand may not produce sand may be as follows:

1.Sand clogging: During the use of the sandblasting machine, the sand may clog the nozzle or sandblasting pipe due to moisture, agglomeration or excessive particles, resulting in the inability to spray sand normally. The solution to this problem is to clean the nozzles and pipes to ensure that the sand flows smoothly.

2.Insufficient pressure: The sandblasting machine needs a certain pressure to spray out the sand, and if the pressure is insufficient, it cannot be sprayed.

This is due to problems with the compressed air source, such as insufficient compressor pressure or blocked compressed air pipes. The solution to this problem is to inspect the compressor and piping to make sure that the requirements are met.

3.Nozzle wear: The nozzle of the sandblasting machine may wear out after a long period of use, resulting in the sand being unable to be sprayed properly. Solve this problem and replace the nozzle to ensure that the nozzle passage is unobstructed.

4.Improper selection of sand: Different sandblasting machines are suitable for different types of sand, and if you choose a sand that is not suitable, it may not be sprayed properly. The solution to this problem is to choose the right sand material and choose according to the requirements of the blasting machine.

In short, the reason why the sandblasting machine only sprays air but does not produce sand may be due to sand blockage, insufficient pressure, nozzle wear or improper sand selection. Check and solve according to the specific situation to ensure that the sandblasting machine can spray sand normally.

It should be that the sandblasting nozzle is blocked, but not all of it is blocked, so it can't generate enough negative pressure and can't suck the sand; In addition, if the sand suction pipe is damaged and leaking, you will definitely find the problem after careful inspection, and there is not enough wind pressure or flow rate.

The sandblasting nozzle is blocked (not completely blocked, so it can not produce enough negative pressure, and the sand can not suck the sand), or the sand suction pipe is damaged and leaking, in short, there is a leak or blockage, and the problem will be found by careful inspection, and there is not enough wind pressure or flow is not enough, and the general pressure at the open end is more than two pressures to use. That is, there must be a large air compressor to drive the sandblasting machine to do it.

The sand channel or spray gun is blocked, and the sand channel and spray gun are carefully inspected.

There is also a possibility that the air inlet of the sand adjustment valve is all sealed and cannot form a sand suction condition.

The last possibility - no sand.

There are a lot of questions.

1: Is the sandblasting pipe blocked?

2: Has the spray gun been deformed with the change of spray gun.

3: Is the small nozzle replaced with a suitable nozzle?

4: The sand is not enough to add sand.

5: The ventilation port of the sand mixing valve is blocked, check the sand mixing valve and adjust it well.

It is the spray gun or sand pipe that is clogged.

You go and ask the manufacturer of the sandblasting equipment you bought, he should know what's going on, in fact, there are a lot of problems, and the trade secrets are not disclosed here.

There may be several reasons why the sand blasting machine is not effective:

Nozzle clogging: If the nozzle is clogged with sand particles or other debris, it will cause the sand blasting machine to have a poor sand suction effect. At this time, it is necessary to stop the nozzle to clean it.

High sand humidity: The high sand humidity of the sandblasting machine will affect the fluidity of the sand and lead to poor sand suction effect. The solution is to dry the sand.

The particle size of the sand is too large or too small: If the particle size of the sand is not suitable for the nozzles and pipes of the blasting machine, it will affect the sand suction effect. It is necessary to select the appropriate sand according to the requirements of the sandblasting machine.

Insufficient pressure: If the pressure output of the air compressor is insufficient, it will affect the sand suction effect of the sandblasting machine. It is necessary to check whether the output pressure of the air compressor meets the requirements of the sandblasting machine.

Sand adheres to the inner wall of the pipe: If the sandblasting machine is not used for a long time, the sand may adhere to the inner wall of the pipe, resulting in poor sand absorption. This is where the pipes need to be cleaned.

In short, the poor sand suction effect of the sandblasting machine may be caused by a variety of reasons, and it is necessary to analyze the specific problems, find the causes and take corresponding solutions.

The sandblasting nozzle is blocked (not completely blocked, so it can not produce enough negative pressure, and the sand can not suck the sand), or the sand suction pipe is damaged and leaking, in short, there is a leak or blockage, and the problem will be found by careful inspection, and there is not enough wind pressure or flow is not enough, and the general pressure at the open end is more than two pressures to use. That is, there must be a large air compressor to drive the sandblasting machine to do it.

Sandblasting rust removal is the use of compressed air, a certain particle size of sand sprayed on the rusted surface of the parts through the spray gun, not only fast rust removal, but also for painting, spraying, electroplating and other processes to prepare the surface, sandblasted surface can achieve clean, a certain roughness of the surface requirements, so as to improve the binding force of the covering layer and the parts. The compressed air used for sandblasting must be treated by a cooling device and an oil-water separator to ensure dryness and oil-free air; Oil-water separators must be cleaned regularly. The distance between the nozzle and the surface of the base steel should be 100 300mm, and the non-sandblasting parts should be shielded and protected before sandblasting.

1. The sand is wet but not dry.

2. Sandblasting or abrasive valve blockage.

3. The safety gas path is cut off.

4. The main pressure regulator is broken.

5. The pressure regulator valve for control is broken.

6. The foot switch is not adjusted well or damaged.

These reasons are possible, you can go to our** to find out, you can use the search Zhaoshun sandblasting machine**, directly send the link can not be sent, sorry, there is a lot of knowledge about sandblasting, you can also consult me if you have any questions.

Hello dear 1To see whether you use a box-type manual sandblasting machine or an automatic sandblasting machine, I want to know first. 2. If it is a manual sandblasting machine, you only need to check the following points to solve the problem of only gas and no sand.

3. First of all, check whether the sandblasting nozzle and sandblasting pipeline are blocked 4, check whether the sandblasting pipeline is damaged and leaking, and it is not easy to be damaged for several years in general. 5. Take out the nozzle to check whether the rubber ring is damaged, and then see if the air core inside the spray is worn. 6. Check whether the sand material in the sand storage bin is enough, and then see if the joint of the sand blasting pipe connection and the sand storage bin has fallen off.

7.According to the thickness of your sand, change to the appropriate model of mouthpiece and adjust the appropriate air pressure. 8. There may be debris in the pipe, and your piece of cloth can dredge the pipe by stepping on the air pressure a few times against the sandblasting head.

The sand blasting port of the manual sandblasting machine has sand out, and the pressure is normal, but the sand cannot be sprayed, what is the reason?

The sand blasting port of the manual sandblasting machine has sand out, and the pressure is normal, but the bucket hand cannot spray sand, what is the reason? Hello! 1.

The sand in the blasting bucket has been used up: after deflating, refill the sand. 2.

The nozzle is blocked by foreign objects: After the blasting machine is turned off and deflated, turn the nozzle sleeve down to check whether the sandblasting nozzle is blocked by foreign objectsThe blast pipe is blocked by foreign objects:

4.(No sand regulator model) the pipe is blocked by foreign bodies and too much sand: after shutting down and venting the potato bucket gas, first turn the nozzle sleeve down, re-inflate the sandblasting cylinder, and then the thrust valve is fully opened, and use the air pressure to use the sand in the pipe 5

There is a sand conditioner model) The pipe is blocked by foreign objects and too much sand: after shutting down and deflating, turn the nozzle sleeve down first, hoping to help you!
