Why is the sprayer not pressurized? What is the reason why the sprayer can t press

The air pressure of the sprayer cannot go up. Maybe the beads are stuck. Workaround:

Rinse the beads well and you're ready to use. The suction canister is set under the gun, and compressed air is introduced from the tail of the gun. When the trigger is opened, the negative pressure generated by the high-velocity air stream sucks the paint out of the tank and sprays it out in a mist with the air flow.

It is suitable for spraying paint and other coatings, so it is also called paint spray gun. The self-blanking tank is located above the spray gun, and the paint falls to the muzzle by its own weight and is sprayed with compressed air (also called a bucket gun), which is suitable for spraying paint containing solid particles.

If the pressure setting of the coater is too low, the pressure will increase. The filter is clogged and can be cleaned and replaced at the inlet of the pipe. If the nozzle is too large or damaged, the nozzle can be replaced. Poor connection of sprayer parts causes the straw to leak. Tighten and inspect the suction tube.

Cause of failure: The slider and slide plate are seriously worn, and the sealing is not good, resulting in the direct discharge of part of the air, the reduction of the air intake of the cylinder, and the insufficient spraying pressure caused by the reduction of piston thrust.

The slider is deformed after long-term use, and the airflow cannot press the slider to the slide plate, resulting in air leakage.

After long-term use of the cylinder, the O-ring in the cylinder is worn, and the air is channeled in this part, resulting in insufficient air pressure.

Exclusion method: Remove the air distribution block and slider, put the metallographic sandpaper on the flat plate, the slider or slide plate is buckled on the sandpaper, and the hands are smoothly pushed and polished, and wiped clean.

You can use red ink or red powder to check, if there is a uniform red ink on the two planes, it means that it has been smoothed, otherwise it is pushed and ground again, and after smoothing, wipe and clean 20 engine oil on the slide plate and the inner cavity of the slider, and assemble it as it is.

The deformation of the slide can be sanded separately until it fits flexibly with the reversing piston.

Open the cylinder, replace the worn O-ring, and apply clean 20 oil to the cylinder bore.

This situation is usually due to the wear of the sealing ring or the problem of the two check valves, that is, internal leakage. The machine can't stop.

Generally, it is the problem that the lower sealing ring or the steel ball seat is not tightly sealed.

Reasons and solutions for no pressure on the paint spraying machine:1. The pressure setting is too low. - Solution: Increase pressure.

2. There is a blockage. - Solution: Clean and add a filter at the inlet of the suction pipe.

3. The nozzle is too large or worn.

Possible causes of the inability of the device to maintain pressure:

1. The equipment leaks. - Solution: Tighten all parts of the equipment.

2. Air leakage of suction pipe. - Solution: Tighten and check the suction tube.

3. The lower steel ball is worn or blocked. - Solution: Clean or replace the lower steel ball.

4. Upper and lower sealing rings.

Wear and tear. - Solution: Replace the upper and lower sealing rings.

5. The upper steel ball is worn or blocked. - Solution: Cleaning or replacing the upper steel balls.

6. The ball seat is worn. ——Solve the problem of cavity rock: replace the ball valve seat.

7. The rotary switch is worn. - Solution: Replace and repair the rotary switch. First check whether the power supply has electricity, then check whether the automatic switch can work normally, and finally check whether the motor is good or bad.

If the sprayer can't pressurize, it may be due to the following reasons: leakage 1Insufficient compressed air:

Please check that the compressor or air source is working properly and whether there is sufficient air pressure output. 2.Gun clogging:

Please clean the spray gun and make sure it is clear. 3.Nozzle clogged:

Please clean the nozzle and make sure it is unobstructed. 4.System Leaks:

Please check whether there is any air leakage in the system, such as the connection of the trachea, the connection of the barometer, etc. 5.Excessive moisture in the gas:

The reasons why the sprayer does not have air pressure are as follows:

1.If the pressure is set too low, the pressure can be increased.

2.The filter is clogged, it can be cleaned and replaced at the inlet silver deficit of the tube.

3.If the nozzle is large or damaged, the nozzle can be replaced early.

Reasons why the sprayer does not absorb material:

1.If the ball is not closed tightly or stuck, negative pressure cannot be formed in the pump body, resulting in no suction. The solution is to remove the impurities that enter the pump body so that the steel ball can move freely and be in full contact with the valve seat, so that it can be.

2.The seal is damaged.

The correct way to use the sprayer:

1.Add water to the putty powder in a bucket and stir it into a paste.

2.Then open the lid of the putty spraying machine, pour the stirred putty paste into it and cover the lid Lu Xiaozi, and pressurize the tank.

3.After pressurization, you can directly open the air valve and spray on the wall.

1. If it is a diaphragm machine, then the hydraulic oil is added.

2. If it is a plunger machine, then the separator oil is added, that is, the special oil for the spraying machine. <>

Summary. What's going on with the sprayer air pressure not coming up.

Hello dear, it is generally because of the leakage of the equipment, the leakage of the suction pipe, the wear of the upper and lower steel balls or sealing rings, etc., which will lead to the problem of no pressure.

If it is caused by water leakage of the equipment and suction pipe, the parts on the equipment and the suction pipe can be tightened, and if there is damage, replace it with a new one; If the upper and lower steel balls or sealing rings are worn, it is safe to replace them.

Hope mine is helpful to you, thank you and have a great day!

What's going on with the sprayer air pressure not coming up.

What is the matter with the air pressure of the spray coating machine, it is generally because of the air leakage of the equipment, the air leakage of the suction pipe, the wear of the upper and lower steel balls or the sealing ring, etc., which will lead to the problem of Sun Yuzai's no pressure. If it is caused by water leakage of the equipment and suction pipe, the parts on the equipment and the suction pipe can be tightened, and if there is damage, replace it with a new one; If the upper and lower steel balls or sealing rings are worn, they must also be replaced to be safe, I hope mine is helpful to you, thank you, I wish you a happy life!
