Shotcrete Equipment Manufacturer
The shotcrete equipment is widely used in mines, tunnels, culverts, subways, hydropower projects, underground engineering, and coal-fired high-altitude mine roadway shotcrete construction operations; various types of industrial furnaces, furnace lining refractory spray molding or repair; various slope protection greening during construction, soil transport, and spraying. The shotcrete sprayer machine can be used for both tidal spray and dry spray and various fiber jet operations. In addition, we also have shotcrete trucks, mortar spraying machines, hydroseeding machines, fog cannon machines, sandblasting machines, gypsum spray plaster machines, GRC machines, wet shotcrete machines, etc. Contact us now!【WhatsApp/WeChat/Phone/Skype】+86 136 1385 6800
The shotcrete sprayer is used in dry spray, tidal spray, and wet spray concrete. It has the characteristics of reasonable structure, stable performance, convenient operation, and long service life. It is suitable for tunnel culvert underground engineering and coal mines, moorland, mine roadways, and jetting. Concrete construction work. This kind of machine is mainly composed of five parts: mechanical power system, feed feeding system, pressure air conveying system, quick-setting agent metering, and adding system, and electric control system.
Use of the Process Should be Noted:
The shotcrete machine is an advanced engineering construction equipment. Its production incorporates many high-tech technologies, so it is very popular among consumers. This kind of machine is also very simple to operate. If you don’t have professional training, you can get started, so don’t worry about the danger caused by not operating. Today, I will tell you some problems that should be paid attention to during the use of the machine to extend its service life of the machine.
During the operation of the machine, it is strictly forbidden to clean the material cavity with a long stick to avoid serious accidents causing injury.
It is strictly forbidden to wash the electric control box, vibration motor, and main motor with water when cleaning the machine, to avoid short circuits and affect the normal operation of the machine.
When used in underground coal mine production, the parts in the safety standard list of the safety standard shall not be replaced by the user.
The machine is used to prevent long and large objects such as steel bars and iron plates from entering the rotor cavity during use to prevent accidents caused by the machine.
When the shotcrete machine is working on shotcrete, if there is no material to be sprayed out at the nozzle, there are usually two situations:
First, when the pipe is to be blocked, the conveying pipe is not blocked, but the conveying condition inside the conveying pipe deteriorates. At this time, the vibrator should be closed, and the mixing in the conveying pipe. The material is injected and the pressure in the pipeline is restored to the normal working range and then turned on.
Second, if the pipe is blocked, the pipeline has been blocked, then the machine should be shut down, and then the pipeline should be cleaned. When the pipeline is confirmed to be fault-free, please restart the machine to resume normal operation.
Standard Operating Specifications of YG Gunite Machine:
The preparation of the operation:
Check whether the shotcrete machine is in good condition and whether the power supply is running at no load. The friction plate is fastened and no air leakage is allowed.
Connect the Fengshui pipeline, open the air supply and water supply valves, check the wind pressure and water pressure, and check whether the Fengshui pipeline is leaking, leaking, or unblocked. If there is any problem, deal with it in time.
Check if the delivery pipe is damaged and replace the delivery pipe when there is damage.
Rinse the rock face with high-pressure water before spraying. ( The loose rock and expansive surrounding rock are strictly prohibited from washing the rock face with high-pressure water, and the crushed wind can be used to remove rock powder and gravel ).
Pay Attention to During Routine Maintenance:
Shotcrete accessories–sealing plate and rotor lining are the key parts of the shotcrete machine, we must pay attention to their maintenance, to ensure that there is no failure in the work.
The anti-adhesive cavity and the discharge elbow have an anti-stick function and generally do not stick during work, but the rotor should be opened after the end of each shift, and the elbow should be inspected and cleaned.
Always pay attention to the maintenance of the sprayer reducer.
After every shift, the mixing materials such as the mixing material on the outer surface of the reducer should be cleaned up in time.
Always observe the oil mark. When the oil is insufficient, it should be filled in time.
The oil should be replaced after 250 hours of work ( about three months ).
The rotor square shaft bearing grease should be filled in time ( the oil filling port on the top of the square shaft ). Every 8 hours the shotcrete machine needs to be shut down for maintenance and repair to ensure that the spray rotating boom is running normally; when the spray stop time exceeds 10 minutes, the spray gun and the slurry pipe should be cleaned in time, and the disassembly, cleaning, installation, and commissioning should be strictly carried out according to the instructions. Use a spray gun to maintain the spray gun’s performance.
