After choosing the mortar spraying machine, sometimes mechanical failure will occur in the process of engineering work to affect the construction progress, not to affect the construction progress will increase the construction cost, how to avoid mechanical problems in the construction? Small make up for you to talk about common trouble, how we should deal with, how to solve.
One, spray machine flow is small, and the flow is not uniform
In the process of construction spraying, the sudden decrease in flow or uneven discharge, there are generally the following reasons, the distance of the grouting machine pipe too long will cause the lack of flow, normal use control within 40 meters, the distance between the mortar and the wall of the friction. Mortar spraying machine spraying basically no floor ash, save water, save material, can reduce the cost of more than 20%. Pressure increases, resulting in a gradual decrease in flow. The air rod movement in the spray gun leads to uneven discharge. Before each spraying, check the distance between the air rod and the spray gun, and the distance between front and rear. Abnormal discharge air will also appear poor atomization phenomenon, can check the air.
Solution: the compressor operation is normal, the general air pressure between 0.4-0.6mpa is normal, at the same time check whether the air pipe is leaking, whether the air rod is blocked. After the work of the mortar spraying machine, it is necessary to drain the surplus material in the hopper, and pour enough water into the hopper, clean the hopper, start the pump, clean the hose and sprinkler head, until the pump is full of water, so as to avoid the surplus material in the hose solidification, plug the hose and sprinkler head.
Second, the causes and solutions of mortar pipe plugging
Spraying high pressure tube jam phenomenon, conveying distance too far when spraying, high altitude pressure is too high, the other is a spray gun mouth foreign bodies blocked, and make the mortar tube pressure, make the interface produces secrete water phenomenon, caused the tube jam phenomenon, the phenomenon of blocking pipe phenomenon is usually a precursor, in the process of spraying flow rate decreased significantly, work pressure increasing at the same time, the staff to stop in time, the early stage of the blocking pipe generally at discharging port, and take over the cleaning easier. Mortar spraying machine price investment is small, the income is big, if every day each spraying equipment spraying 1000㎡, according to the market average price of 4 yuan per ㎡ calculation, excluding the worker's salary of about 1000 yuan, every day each equipment can make a profit of 3000 yuan, excluding other factors, annual income of more than 500,000 yuan.
Solution: if not stop in time is the pipe seriously blocked, can only clean the pipe with water to eliminate, choose the appropriate hose right down and up for washing.
Three, the main motor can not start
Mortar conveying distance is too long, make mortar conveying resistance increases, exceeding the effective load of the motor within effective jet distance mortar spraying machine, so try to shorten the transportation distance, centrifugal and insufficient lubrication resistance increase, each with a professional oil pump forced a lubricating oil filled to reconcile, external power cord interloper, power cord within 50 meters with national standard 6 square line, power cord never conditions caused by abnormal voltage current.
Air compressor cannot start
Solution: the pressure switch is too high, or the air compressor switch is not open, the air valve switch on the gun is not open. The air needle in the spray gun is blocked. Start the air pump every time you start the machine, and turn off the air pump after shutdown to prevent the cement slurry from backflow into the air needle and causing blockage.
