What is the spray concrete spraying process? How to operate the wet power sprayer? Henan Yuli Wet Spraying Machine Manufacturers analyzed in detail the wet concrete sprayer's sprayed concrete work flow, including the preparation work before the start-up of the wet damper, the work in the shotcrete construction, and the work after the shotcrete was completed, hoping to correct Operation of wet spray machine is helpful.
First, the preparation of the wet power sprayer before starting up 1. Fix the wet spray machine on a solid foundation, no one leg is allowed to hang, the delivery pipe must be reinforced, and the pipe must be installed properly. No leakage is allowed. Material place.
2. Connect the three-phase power supply and check the lubricating oil level (the liquid level gauge inside the tank) must not be lower than the liquid level gauge.
3. During work, no hands or foreign objects should be put into the screen and all active parts to avoid danger.
4. Check that there are no loose parts in the hopper and all moving parts. There must be no loosening of loose parts. If there is looseness, it must be reinforced. The hopper screen must be tightly closed before proceeding to the next step.
5, check the electronic control system, all switches in the off position, check the electrical should be no abnormal loose.
6. Close the air switch in the lower right side of the electric control box and close the two small air switches on the upper left side. Check the power supply voltage and do not lower than 380V±10%. Unscrew the emergency stop button and start the control power start button. The button lights up. After the left hand presses the motor stop button, the right hand presses the motor start button, the right hand clicks the motor start button, and the left hand presses the motor stop button immediately (the start time must not exceed 5 seconds). Observe the motor steering. If the steering is reversed, replace the power supply wires with two wires. Test the motor so that the motor rotates in the forward direction. If the motor turns to the opposite direction, the pump will be damaged.
Second, the wet damper spray shotcrete construction work 1, start the motor start button, let the motor run for 5 minutes, according to the positive pump start button, let the pump empty play for 10 minutes, after the stop, the remote control knob is converted into far control.
2. Fill the hopper with water and press the pump start button to pump 1-2 buckets of water. After the pump is finished, stop the pump operation and immediately pour in the slightly thicker mortar. After stirring, press the positive pump. The start button, after pumping 2-3 buckets of mortar, can be pumped into the appropriate concrete (requires to ensure that the slump of the concrete is between 14-20 cm). When pumping concrete, the concrete in the hopper must not be lower than the agitator shaft to prevent concrete from splashing out of the hopper.
3. During the construction of sprayed concrete, always check the cooling water source and the oil level of the oil temperature table no higher than 50°C. The pressure gauges and voltage and current meters should work normally. If the oil temperature is too high, the cooling water flow rate should be increased. The oil pressure filter pressure gauge When the pointer reaches the red area, it should be removed and cleaned with gasoline. The filter element should be replaced when the return filter pressure gauge reaches the red area.
4. During work, in the event of an emergency (such as abnormal sound of the motor), the emergency stop button should be turned off without hesitation. After the fault is removed, the emergency stop button can be restarted. When the power is turned on again, the switches should be in the open position. If it is determined that the failure cannot be resolved within one hour, the concrete in the hopper, the transfer cylinder, the S tube, and the pump tube must be cleaned.
5, in case of blockage in the work, you can anti-pump 1-2, and then open the positive pump, so repeated two times, the general blockage that can be ruled out, if still can not be ruled out, should stop the positive pump, remove the plugged pump tube After cleaning, you can continue pumping concrete.
3. After the wet concrete sprayer has finished spraying, after the completion of the shotcrete operation, add enough water to the hopper, clean the concrete in the cylinder, open the valve under the hopper, and clean the concrete in the hopper with water. Open and back the pump, add clean water from the outlet to continue cleaning, until the hopper out of clean water, close the valve below the hopper, will be fitted with a sponge ball reduction tube connected, remove the pump tube front hose.
2. Add enough water to the hopper and ensure that the water is sufficient. Open the pump and start washing. During the washing process, do not stop the pump or back pump until the sponge ball is pumped out from the front of the pump tube. Open the valve under the hopper and open it again. The pump will pump the water out of the pipe and let it run.
3, open the pump or anti-pump, let the pump run for 10 minutes, and check the mixing bearing, S tube bearing, until the lubricant can be stopped (first press the pump stop button, then press the motor stop button, and then press Emergency stop button) Pull down the air switch in the lower right side of the electric control box.
4. Exhaust the water in the water tank, and clean the water tank, turn off the cooling water source, check whether there is concrete in the hopper, the S pipe, and the conveying cylinder, and clean it in time.
Note: After the winter construction is stopped, the cooler must be removed from the water pipe and the water must be drained. Every time the hydraulic system is repaired, the power must be turned off and the tools must be kept clean for repair.
