How to safely operate wet sprayer? The Henan Yuli Wet Sprayer manufacturers analyzed the safety operation procedures of the Yuli Wet Sprayer in detail, including the preparation work before the start-up of the Yuli Wet Sprayer, the shotcrete operation flow, and the precautions for safe operation. It is hoped that it will be helpful for everyone to use the wet sprayer. .
First, the preparation of the wet power sprayer before starting up 1. First, the wet spray machine is fixed on a solid basis, the spray pipe must be reinforced, and ensure that the pipeline is installed, there must be no leakage.
2. Connect the three-phase power supply and check the lubricating oil level. It must not be lower than the liquid level meter.
3. Check that there is no foreign matter in the hopper and in any moving parts. The parts must not be loosened. If they are loose, they must be reinforced. The hopper screen must be tightly closed.
4, check the electronic control system, all switches in the off position, check the electrical appliance should be no abnormal loose.
5. 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 light is on. 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 concrete operation process 1, start the wet sprayer, let the motor run for 5 minutes, according to the positive pump start button, let the pump empty play for 10 minutes, stop, the remote control knob is converted to remote control.
2. Fill the hopper with water, press the pump start button and 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 put into the appropriate concrete to start pumping. Note that when spraying 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 operation of shotcrete, always check the cooling water source and the oil level of the oil temperature table no higher than 50°C. The pressure gauge and voltage ammeter 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 case of emergency, the emergency stop button should be turned off without hesitation. After the troubleshooting, 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 the event of a blockage of the work, can be anti-pump l ~ 2, and then open the pump, so repeated two times, the general block that can rule out, if still can not be ruled out, should stop the positive pump, remove the plugged pump tube After cleaning, you can continue to spray concrete.
III. Precautions for the safe operation of 耿力湿喷机 1. Add enough water to the hopper, open the pump to clean the concrete in the cylinder, then open the valve under the hopper, and clean the concrete in the hopper with water; open and return the pump from the outlet Add clean water to continue cleaning, until the hopper out of clean water, close the hopper bottom valve, remove the pump tube front hose.
2, add enough water to the hopper, and to ensure adequate water, open the pump to start washing, washing process, do not stop the pump or anti-pump, open the valve under the hopper, and then open the anti-pump, the water in the pipe back and exhaust .
3, open the pump or anti-pump, let the pump run for 10 minutes, and check the mixing bearing, S-size bearing, until the lubricant can be shut down.
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.
