Second, the hydraulic wet spraying machine sprayed concrete operation process
1. Start the hydraulic wet spraying machine, fill the hopper with water, and press the positive pump start button to pump 1-2 buckets of water. After the pump is finished, stop the positive pump and immediately pour in a slightly thicker mortar and wait for stirring. After the uniformity, press the positive pump start button, after pumping 2-3 buckets of mortar, you can put in the appropriate concrete and start pumping. Note that when spraying concrete, the concrete in the hopper must not be lower than the mixing shaft, so as to avoid injury from concrete splashing from the hopper.
2. During the sprayed concrete operation, always check the cooling water source and oil temperature gauge. The oil level must not be higher than 50 ° C. The pressure gauges and voltage and current gauges should work normally. The oil temperature is too high to speed up the cooling water flow rate. When the pointer reaches the red area, it should be removed and washed with gasoline. When the pressure gauge of the return filter element reaches the red area, the filter element should be replaced.
3. During work, if there is an emergency, you should not hesitate to turn off the emergency stop button, and then restart the machine after the fault is removed. When restarting, ensure that the switches are in the on position. If it is determined that the failure cannot be resolved within 1 hour, the concrete in the hopper, the conveying cylinder, the S pipe and the pump pipe must be cleaned.
4. If there is a blocked pipe during work, you can reverse pump 1-2 times, and then turn on the positive pump. Repeat this two times. Generally, the blocked pipe can be ruled out. If it still cannot be ruled out, stop the positive pump and remove the blocked pump pipe. After cleaning, spray the concrete.
