Release time: 2017-04-18 15:03:27 source: itforthai.com

   The sprinkler must be used in accordance with the vehicle operating specifications when in use, and cannot be acted upon in accordance with experience, otherwise it may cause malfunctions and serious damage to vehicles. Therefore, Chengli sprinkler manufacturers remind you that you must read the manufacturer's instruction manual carefully before operating the sprinkler .
   Chengli Sprinkler Factory will explain the operation methods of sprinkler power take-off, air control switch, and music horn in detail. As the "operating method of sprinkler valve" is more complicated, we will explain it in a separate article for you.
I. Power take-off operation
First start the sprinkler . When the engine speed reaches the starting state, depress the clutch pedal when the transmission gear is in the neutral position. The power take-off is sufficient and the shaft sleeve is pushed so that the power take-off and the transmission are engaged (oil brake power take-off). Pull the joystick back). After pulling out the handle for about 5 seconds, make sure that the power take-off and the gearbox are fully engaged (do not hang the power take-off during driving, otherwise the power take-off and the gearbox will be damaged). At this time, slowly release the clutch pedal, the engine idling or Slowly accelerate the pump to the normal working speed, and the sprinkler pump can work normally. The work of the sprinkler pump can be judged by whether the sprinkler pump and the power take-off drive shaft rotate. After the sprinkler operation is completed, depress the clutch pedal and turn off the power take-off operation switch (the oil brake vehicle is a manual power take-off and the front rod is pushed back in place). After 5 seconds, release the clutch collapse plate, and the power take-off is separated from the transmission power The pump ends.

Notes on the use of power take-off:
1: It is strictly forbidden to pull out the power take-off handle when the air pressure is insufficient (starting air pressure), otherwise the transmission and power take-off may be damaged due to the incomplete engagement of the power take-off and the gearbox.
2: After pulling out or pushing the power take-off handle, you must wait 5 seconds before releasing the clutch collapse plate to ensure that the power take-off and the gearbox are fully engaged or disengaged, otherwise the gearbox and the power take-off will be damaged.
3: When spraying or using anti-aircraft guns, be sure to open one of the forward or backward sprinkler ball valves, otherwise, the pipeline, pump, and seals will be damaged due to excessive pressure.

Operation of air control switch
The air control switch is used to take air from the gas cylinder of the car. It mainly operates the power take-off (pneumatic) and each line ball valve. Each operation handle is subject to the label attached under the handle. The handle is pushed in the disengaged (closed) state, and the handle is pulled out in the engaged (open) state
Operation of Music Speaker
The music horn is to remind pedestrians to pay attention when spraying, so the music horn should be turned on before the work. The music horn switch is located on the left side of the cab and is a single gear switch. Pull out the switch to turn on the music speaker, and then press it to turn off the music speaker.

Fourth, the operation of the valve
   The first time the sprinkler pumps water, if the sprinkler pump is working for the first time, 20kg of clean water must be injected into the pump. The specific method is to open the imported ball valve, connect the pumping hose, fill the hose with clean water, raise the hose, and let the water enter the pump Inside. Can also be injected by other methods. If the pump has been working and there is already water in the pump, do not add water. The red or concave points on the square valve shaft of the ball valve are aligned with the pumping point (away from the end of the beam), close the remaining ball valves, place the pumping hose 300mm below the liquid surface, and operate according to the power take-off method. The system will enter normal pumping after vacuum State, after pumping, follow the power take-off operation method.
