What are the common faults and troubleshooting methods of sprinkler irrigation machine?

Now the official grain harvest season, sprinkler equipment production is also the peak season, and how to ensure that sprinkler equipment is normal is the most concerned issue for farmers, what are the common failures and troubleshooting methods of sprinkler machines?

The reasons why the pump does not produce water are as follows:

The water storage in the self-priming pump is not enough; the inlet pipe joint is leaking; the suction distance is too high; the rotational speed is too low. The water storage capacity should be increased, the sealing ring should be replaced, the suction range should be reduced, and the rotational speed should be increased.

The reasons for insufficient water output are as follows:

The inlet pipe strainer or the self-priming pump impeller is blocked; the lift is too high or the speed is too low; the impeller is leaking at the ring. The blockage of the credit filter or impeller should be cleared; the head should be reduced or the speed should be increased; the sealing ring at the ring should be replaced.

The reasons for water leakage in the water pipeline are as follows:

Quick joint sealing ring wear or crack; there is dirt on the contact surface of the joint. The sealing ring should be replaced and the contact surface dirt of the joint should be removed.

The reasons why the sprinkler does not turn are as follows:

The rocker arm installation angle is wrong; the rocker arm installation height is not enough; the rocker arm is loose or the rocker arm spring is too tight; the flow channel is blocked or the water pressure is too small; the gap between the hollow shaft and the sleeve is too small. The relative position of the water baffle and guide plate and the flow centerline should be adjusted; the rocker arm adjustment screw should be adjusted; the pressure plate screw should be fastened or the rocker arm spring angle should be adjusted; the blockage in the flow channel should be removed or the working pressure should be adjusted; the hollow shaft and sleeve should be polished or replaced.

The reasons for the unstable work of sprinklers are as follows:

The installation position of the rocker arm is incorrect; the rocker spring is improperly adjusted or the rocker shaft is loose; the commutator failure or serious wear of the rocker shaft; the protuberance height of the commutator swing block is too low; the friction force of the commutator is too large. Adjust the height of the rocker arm; adjust the rocker spring or tighten the rocker shaft; replace the commutator spring or rocker sleeve; adjust the height of the pendulum block; fill the pendulum block shaft with lubricating oil.

The sprinkler has a small range and the reasons for uneven spraying are as follows:

The rocker arm striking frequency is too high; the rocker arm height is not right; the pressure is too low; the flow channel is blocked. The rocker arm spring should be adjusted; the rocker arm adjusting screw should be adjusted to change the rocker arm draft depth; the working pressure should be adjusted; and the blockage in the flow channel should be removed.
