As an industrial processing equipment, the sandblasting machine will inevitably fail when it is used, and the failure can be found and solved in time to better use the equipment. For the production service. There are many types of sandblasting machines, here is mainly an explanation of the failure and solutions of the liquid sand machine, if the product of the enterprise is not the type of liquid sandblasting machine, you need to ask the manufacturer for an explanation.
1. The motor rotates, but the abrasive pump cannot produce the abrasion, or the spray gun does not discharge the liquid, and the abrasive pressure is low.
Cause of failure: aThe motor is rotating in the wrong direction. b.The level of the grinding liquid in the tank is too low. c.Excessive abrasive addition to the tank. d.Blockage in the sand road or spray gun. e.Leakage in the stirring circuit. f.The impeller is loose or heavily worn. g.The abrasive pump inlet or outlet is blocked.
Corresponding solution: aChange the motor steering. b.Fill the tank with water to the overflow. c.Make the abrasive meet the specified dosage dCheck to clean the sand road and spray gun. e.Check and rule out leaks. f.Tighten the screws that hold the impeller in place or replace the impeller gCheck and remove the blockage.
2.Apparently leaking from the top of the casing on the grinding pump when working.
Cause of failure: aThe tank overflow port is clogged. b.The exhaust port on the top of the cabin is clogged. c.The abrasive pump drain is clogged. d.The splash jacket on the abrasive pump shaft is detached or damaged.
Workaround: aCheck and remove the blockage. b.Check and remove the blockage. c.Check and remove the blockage. d.Retighten or replace.
3.It appears that the proportion and level of the grinding liquid in the storage tank are normal, but the grinding liquid is not circulating during work.
Cause of failure: aThe abrasive pump inlet is blocked. b.The grinding liquid pump is blocked through the strainer.
Workaround: aCheck and remove the blockage. b.Check and remove the blockage.
4.Appearance airbrushes do not squirt.
Cause of failure: aThere is a leak in the gas path or a broken hose. b.The gun inlet check valve rubber ball is damaged. c.The gun valve is clogged or broken. d.Clogged or damaged filter regulators. e.The solenoid valve of the air circuit is blocked or damaged.
Workaround: aCheck and rule out leaks or replace hoses. b.Replace the check valve balls. c.Remove blockages or replace air valves. d.Remove blockages or replace filter regulators. e.Eliminate blockages or replace solenoid valves.
5.The processing efficiency of the appearance is low.
Cause of failure: aThe compressed air pressure is on the low side. b.Incorrect abrasive selection. c.It could be one of the issues.
Workaround: aIncrease the air pressure appropriately. b.Correct selection of abrasives. c.Symptomatic resolution after confirmation.
When using, the air pressure is too low, the motor is reversed, and too much sand is added.
