Here, by the introduction of another unit cyclone wind, the wind was long spiral state disperse the material, speed, and rotating it float into the conveying pipe, to reach the nozzle and then add a small amount of added water is ejected. Wet spraying machine structure: mainly by the drive means, the rotor assembly, gas system, injection system and electrical control box and other components. Wet spraying machine for relatively poor field conditions, minimal amount of maintenance. However, as with all rotor sprayed concrete machine, must often maintenance. 1. seal plate and rotor liner is the key element of this device, they must pay great attention to maintenance, to improve their life. Rotor clamping force applied to the sealing plate clamping system over the entire plate surface distribution is uneven, the residual gas in the discharge port and the largest port, and the maximum clamping force point with the rotation of the rotor drift back and forth constantly. This difference in pressure by a four-point clamping system to solve, so that when the machine is running extremely slight combination of surface leakage. Therefore, the correct use of the machine for worn clamp consumption costs have an important impact. Before the class began to spray concrete work, to check the clamping force applied to the rubber pad and rotor liner. Because the pressing force is too small, it will cause air to escape from the junction of the two plates, carrying fine particles will enter between the two plates, rubber plates and rotor exacerbate liner wear; if the pressing force is too large, due to friction overheat and cause excessive wear of the seal plate, seal plate heat limit is 110 ° C, generally use no more than 80 ° C below normal. Class work is completed, to clean the machine, especially to the sealing surface of the plate and rotor liner cleaned; the same time to check the wear liner sealing plate and rotor, if the sealing plate has been worn to such an extent: Steel dowels flush with the rubber surface (see Fig. 8), the sealing plate must be grinding, tick tendons or replaced with new boards. Because then the rotor will be in direct contact with the steel backing plate dowels pretension of the sealing plate is not sufficiently effective sealing is obtained, so that it loses tightness. Rotor liner must be checked once a week, if deep scratches (deeper than 1mm) occurs, it should be re-grinding (repair method, see VII). Lining the circular hole edges should always check, it must be kept sharp edges. If the edges are chamfered, fine particles will penetrate the joint surface increases wear and tear, if it was a new seal plate, and the old liner material hole with beveled edges, new life will be significantly sealing plate shortened. Timely grinding rotor liner, removing the worn part, save a lot of hassle and cost savings. 2. The release material chamber and cyclone have release function, it is generally not bonded at work. However, the rotor should be opened after the end of each class of the cyclone were cleaning up. 3. reducer should always pay attention to maintenance and repair: A. reducer lubricants No. 50 industrial gear oil (SY1172-77S), or the 30th machinery oil; B. reducer when working temperature not greater than 40 ° C ; C. Work should be cleaned after each shift gear unit surface adhesion of the mix and other debris; D. always check the oil level, lack of lubricant should be promptly filled; E. total working 250 hours (about three months) after should replace the oil. Wet spraying machine Note This machine adopts pneumatic accelerator pump is a new transport machinery, the use of pressurized air as power source for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous The liquid can be pumped exhaust. The main features of this pump is no irrigation water, pumping both liquid flow, but delivery is free-flowing medium, high suction lift, lift adjustable (0-50 meters) air supply pressure as long as more than 1kg / cm2 That can work, absolutely fire and explosion. Removing non-pressure gas line and conveying line. When sprayed concrete during operation, if the nozzle at the sudden lack of material ejected, then generally there will be two things happens: when one is going to take place in the plugging. Then conveying line while not being blocked, but conveying line conveying internal situation deteriorated, then we should close the vibrator, and other conveying line in the mix ejected, pressure in the pipeline to resume the normal operating range on again. Second, plugging occurs, conveying line has been blocked, then should turn off the machine, and then began to clean up the conveying line (Note: Before you open a cyclone or make conveying pipe line pressure drop restore normal operation to 0), no fault in confirming the pipeline, re-start the machine according to the boot procedures. B. sprayed concrete when conducting operations feeding hopper should try to maintain continuity, so that stable ejection performance. C. In use, the longer prevent large objects such as steel ﹑ materials such as iron debris into the rotor chamber, in order to prevent accidents caused by destruction machine. Machine is running in. Do not use sticks to clean material chamber, so as to avoid severe damage aircraft accidents. D. reduction systems around the vent must be kept clean to prevent blockage caused by channeling the main motor oil and burning motor. E. Never use water wash the electronic control box and the main motor when cleaning the machine, so as to avoid short circuit and affect the normal operation of the machine. F. for coal mine production and use, the high pressure hose by the user to purchase, the connection chain and cables must choose products with safety standard qualification.

Remove conveying pipe from the cyclone, pneumatic valve open, keep the rotor material blown out, and then check the conveying pipe, clogging the site with a wooden stick percussion, vibration or loose plugs emptied (Note: To lose before you open the cyclone feed tube or pipe pressure drops to 0). Finally, the conveying pipe and then received the cyclone, with a pneumatic blow. If the transport distance is over 40m, 20m should deal with each segment of the pipeline. Aggregate sieved. Transporting gas pressure is too low to stop the motor and gas, if the rotor blockage should move away hopper base, open rotor, rotor material cavity clean up with a brush. Improve airflow pressure. System pressure is too low or too thin tube to improve system pressure, increasing the trachea through the radial gas line or gas line is not turned down under after cleaning, open the valve the mix of excessive moisture, spices uneven adjustment spices meet the requirements machine capacity is reduced because the material is bonded or sleeve wear caused by cyclone blockage and clean or replace the cone nesting cavities for a long time without cleaning clogged Clean or replace material cavity due to the bonding material to make material chamber clogged Clean or replace material cavity vibrators Maintenance is not running the vibrator over the air inlet blockage, materials from spill clean up residual gas vent port conveying pipe vibration powerful pneumatic valve installed wrong or pipeline leak caused by too much pressure drop, low air pressure check and make corrections because the material bonding and clogging rotor material cavity or passage of the cyclone See reduce airflow blockage part of the main gas line area is not enough to change the diameter of the main gas line to reach the required standard machine vibration spring wear, resulting in reduced height hopper, vent gap adjustment or replacement of inadequate mixing vibration spring expected slump inappropriate, spices uneven adjustment meet the requirements spices start to block airflow pressure delivery valves to adjust the amount of gas pressure too low Check the slurry viscosity is too uneven to adjust the ratio of spices mixed with water stream Debu full water pressure is too low Check the water pressure (nozzle at least 0.3MPa) water loop inlet orifice nozzle check nozzle clogging and clean, if necessary fashion Sheung Shui filter dust at the nozzle too much water was added to increase the amount of water nozzle outlet nozzle drops Pulp add too much water to reduce the amount of water sprinklers rebound is too large (greater than 15% spray wall spray top is greater than 20% -30%), inadequate screening examination material grading curve, sprinkler adjustment when necessary to spray from the spray by plane Spray too increased to 0.8m from the jet direction and that is not correct spray jet angle perpendicular to the surface by the spray nozzle from the surface of the standoff distance is too far reduced to about 1m Company Profile Shandong Jia letter Machinery Co., Ltd. is a leading industrial and mining enterprises provide professional equipment and technical advice business.
