Henan Yuli support is a professional sprayer manufacturer, sales of HaoLi spraying machine, Yongli automatic spraying machine, dry spraying machine, concrete spraying machine, automatic feeding spraying machine, spraying machine accessories. The ten steps of safe operation of wet spraying machine:
1. The sprayer is connected to the power supply to check whether the connection points of the electronic control system circuit are firm and whether the body is reliably grounded and whether there is any leakage phenomenon.
2, determine the water supply switch valve, clean water switch valve in the off position, the water supply pipe connector and water connection.
3, observe the oil standard, check the host gearbox and metering pump transmission box lubrication is sufficient. 50# industrial gear oil (SY1172-80) or 30# mechanical oil should be added to the transmission of the host machine. N220 or N320 industrial gear oil (GB5903-86) should be added to the metering pump transmission box.
4. Determine the main air passage manual stop valve of the pneumatic conveying system, the manual shutoff valve of each branch air passage at the off position, and the main air pipe is connected to the pressure wind source. 5. Separate the helium conveying pipe and the accelerating agent conveying pipe from the spray head And the body is connected.
6, set the metering pump flow. Loosen the butterfly screw on the front of the metering pump to adjust the handwheel. Turn the handwheel to reduce the flow in the clockwise direction, and increase the flow in the counterclockwise direction. The calibrated value is the percentage of the maximum flow rate. The pump output that needs to be set is the maximum output, that is, the indicator should be set to 74.4% of the position on the scale board. The adjustment handwheel did not make one revolution and the adjustment amount was 25% of the total output. After the flow is set, tighten the wing nut to lock the adjustment handwheel.
7. Set the motor steering, close the power switch to control the power switch, air switch 1DK; press the main motor start button 1OA button, observe that the rotation direction of the rotor body should be consistent with the direction indicated by the arrow. Otherwise, phasing the power input line of the control box.
8, adjust the pressure device. Move the nut on the tensioner rod first by hand to compress it. Then use a wrench to tighten 2-3 turns. Open the main wind road, upper wind road, lower wind road manual shut-off valve, close the auxiliary wind road manual shut-off valve, bend the blank conveying pipe, when the air pressure rises to 0.4Mpa, check the upper and lower sealing plate junction no gas leakage should.
9, check the accelerator delivery system. Close the manual wind-off valve on the upper wind road and the lower wind road, and open the manual wind-off valve of the main wind road auxiliary wind road. Observe that there should be gas leakage at the nozzle. To confirm that the accelerating agent delivery line is not clogged.
10. Make sure that the quick-set coagulant supply switch valve is in the off position, and fill the accelerator tank with liquid accelerator.
