Common faults of siphon sand blasting machine and troubleshooting methods


Siphonic sand blasting machine failure and troubleshooting
Abrasive enters the vacuum bag:

1 Check if the opening of the new dust bag separation adjustment is too large or the abrasive is too thin. After 8 hours of use, the small mouth can be eliminated;
2 Use coarser abrasive

Abrasive is missing on the work site:
1 Check the vacuum bag for holes or unclamping.
2 Replace the dust bag.
3 Re-clamp the dust bag

Unclear vision during blasting:
First, check whether the dust bag is clogged;
2 Whether the vacuum bag is aging or blocked;
3 Whether the abrasive contains too much dust;
4 Whether the recovery pipe is blocked;
5 Whether the air nozzle hole is too large and the compressed air pressure is too high.

If you have the above problems then
1 Replace the vacuum bag. 2 Tap the vacuum bag. 3 Replace the abrasive. Adjust the separator. Adjust the opening of the belt. 4 Check the reason for the clogging of the recovery pipe.

Low processing efficiency:
1 Check if the air pressure is too low; 2 Whether the nozzles and air nozzles are too small; 3 Whether there is too much dust in the abrasive
4 Increase pressure ; 5 Replace larger nozzles and air nozzles, 6 Replace with new abrasive

Sprayed abrasive is uneven:
Check whether there is less abrasive, whether the air pressure is too low, the nozzle is blocked, the abrasive is wet, and the air gap of the separator regulator is too small, so that the abrasive cannot be output.
Add more abrasives, increase the pressure, clear the blockage , add dry abrasives and check the air path to adjust the air gap
Method to clear the blockage: For the siphon type sand blasting machine, the nozzle is directly pressed against the wall of the bin, the pneumatic air source makes it work, and the abrasive is forced back by its own air pressure to make the sand pipe smooth.

No sand blast:
   Note: If 'air and no sand' occurs and the sand tube is suspected to be blocked, you can place the nozzle nozzle spray gun on a flat surface, and then start the sandblasting gun (step on the pedal) to let the high-pressure air blow back from the aluminum base. After removing the nozzle from the flat surface of the sand tube, if the sand still cannot be sprayed out, please check all the following steps.
(1) Check if the sandblasting gun is blocked.Unplug the sand tube (thicker) on the aluminum seat, then press the foot switch, and then place your finger at the entrance of the sandblasting gun. Suction, if there is suction, it indicates that the spray gun is acceptable. If there is no suction, it indicates that the spray gun is damaged or blocked. The damage is as follows: Off, then put your finger at the entrance of the sand blasting center, if there is suction, if there is suction Indicates that the spray gun is usable. If there is no suction, it indicates that the spray gun is damaged or blocked. The damage is as follows: the jet nozzle sheath is worn and the jet nozzle is damaged, so that the jet force cannot be concentrated, and this situation often hurts the aluminum seat and the nozzle sleeve. The more serious one will hurt the nozzle and make the spray gun unusable, so you only need to replace these two parts. (If the nozzle diameter is about 2mm larger than the new nozzle diameter, the nozzle needs to be replaced.)
(2) Check whether the blasting pipe is damaged, and whether the insert of the sand pipe is damaged.If it is broken, replace it.
(3) Check whether the sand blasting pipe is blocked, first remove the sand pipe to check whether there is a blockage in the pipe or the core insert holes on both sides of the sand, if it is removed, it can be removed (i.e. the insert and the lower end of the sand material recovery cylinder). Nozzle insert) There are four blocking situations:
a.The nozzle nozzle sheath is detached, which causes blockage at the nozzle and the mouth, the removal method is to take it down, and then update the jacket.
b. The jet nozzle is not in the correct position or position. The troubleshooting method is: loosen the fixing screw, and then move the jet nozzle forward and backward, and when it is displaced, let it continue to jet, and when it feels the maximum suction, fix it with screws.
c. Sand dust and foreign bodies are blocked. Generally, the blocking position will be between the nozzle and the air jet nozzle, which is caused by high pressure air. The removal method is to turn the nozzle sleeve away, and you can see that the sand pressure has condensed and then scraped it. (Note: When the nozzle cover and the aluminum base are turned away, the nozzle cover must be facing upwards, and then tap twice to turn it, otherwise it is easy to cause the screw teeth to die or be damaged.
d. The nozzle and the nozzle sleeve are not fixed firmly, which causes slippage. The method to eliminate it is to fix the nozzle and the sleeve with instant glue, silicone or other methods.
Possible reasons for poor vacuuming:
(1) The rotation direction of the vacuum motor is wrong.
(2) The cloth bag is clogged, please perform operations as specified in item 2 of the regular inspection and operation items.

(3) The sand material is too thin, so it is mistaken for insufficient dust suction ability, or the sand contains too much dust, please follow the operations in Item 2 of the regular inspection and operation matters.

Illumination does not light:
Check whether the lamp and starter are burned out or the electric wire is short-circuited. The elimination method is: replace the lamp or starter, if the electric wire is short-circuited, replace the electric wire.
Fan motor does not rotate:
(1) For models equipped with an electromagnetic switch, check whether the overload protection switch (thermodynamic translator) of the electromagnetic switch is tripped. The elimination method is: press the red button to restart (when the button thermostat is tripped, the Wait for it to cool down before restarting), and then restart the motor. If the motor is moved together, the overload protection switch will trip again quickly, please check whether the three-phase current is out of phase or the dust suction cloth is blocked too seriously or the motor is damaged. If the forest is damaged, please install the wiring when it is out of phase; clean the dust cloth if it is too dirty, and repair the motor if the motor is damaged. If there is no other problem, it may be because the customer's voltage is lower than normal (operating current) (Larger), which is not suitable for the current value set at the time of factory shipment. At this time, as long as the current setting value of the upper left corner of the protection translator is increased by using a cross screwdriver, the problem of frequent power jumps can be eliminated.
(2) For models with fuses, please check whether the fuses are burnt out. The troubleshooting method is: replace the fuses when the fuses are burned out, and replace the fuses. When the fuses are burnt out soon, please check in detail whether there are other failure points.
5. The dust of the dust collection bag should be cleaned regularly. At least once every used bag of sand should be cleaned. It can be placed in a sand tray to facilitate dumping. If the fresh sand of the same weight is removed each time, it can be sandblasted. Machine, it can ensure that the degree of sand material is often consistent, and it can achieve stable processing quality.
Box type sand blasting machine operation and safety instructions
1. Please read the operation manual carefully before operation and follow the order.
2. Wear safety gear such as gloves, goggles, earmuffs (or earplugs), safety shoes, etc. before operation.
3. When changing the window protective shirt glass, be sure to wear gloves to protect it and be careful not to damage the tempered glass.
4. When replenishing sand material, open one side door and pour an appropriate amount of sand material into the body.
5. The dust collector rocker should be rocked once every 4-8 hours of operation (or before each work or immediately after use). The most effective way to clean the cloth tube is to open the door of the dust collector to pat the cloth tube several times and shake the cloth tube lever after each use.
6. Before shaking the dust collector lever, please turn off the dust collector motor and wait for one minute to completely stop the dust collector blades to prevent dust from piercing the cloth tube.
7. When using alumina, silicon carbide or gold steel sand material, after every one hundred hours of operation, you can turn the nozzle of the blasting gun to a fixed direction by 90 degrees and then tighten the screws of the nozzle. This can greatly extend the nozzle and the aluminum seat. Life.
8. The new sand processing surface is thinner than the coarse sand processing surface, so every time a certain amount of dust is removed (for example, 5 kg), please add fresh sand of equal weight (5kg) to the machine so that the sand in the machine can be maintained. The distribution of wood particle size can make the quality of sandblasted surface stable.
9. The fan blades are not stable, please do not open the door of the dust collector.
