Detailed Explanation of Common Faults of Sprinkler Irrigation Machines and Their Troubleshooting Methods

It is now the official grain harvest season, and the production of sprinkler irrigation machine equipment is also in peak season. How to ensure that sprinkler irrigation machine equipment operates normally is the issue farmers care about most. So what are the common faults of sprinkler irrigation machines and the troubleshooting methods?

Reasons the water pump does not discharge water include:

Insufficient stored water in the self-priming pump; water leakage at the inlet pipe joint; suction lift too high; rotation speed too low. The stored water volume should be increased; the sealing ring should be replaced; the suction lift should be reduced; the rotation speed should be increased.

Reasons for insufficient water output include:

The inlet pipe filter screen or the self-priming pump impeller is clogged; the head is too high or the rotation speed is too low; there is water leakage at the impeller ring opening. The filter screen or the clogged material in the impeller should be cleared; the head should be reduced or the rotation speed increased; the sealing ring at the ring opening should be replaced.

Reasons for water leakage in the water delivery pipeline include:

The sealing ring of the quick connector is worn or cracked; there is dirt on the contact surface of the connector. The sealing ring should be replaced; the dirt on the contact surface of the connector should be removed.

Reasons the sprinkler head does not rotate include:

The installation angle of the rocker arm is incorrect; the installation height of the rocker arm is insufficient; the rocker arm is loose or the rocker arm spring is too tight; the flow channel is clogged or the water pressure is too low; the clearance between the hollow shaft and the shaft sleeve is too small. The relative position of the water baffle, water guide plate and the centerline of the water flow should be adjusted; the rocker arm positioning screw should be adjusted; the pressure plate screw should be tightened 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 shaft sleeve should be polished or the hollow shaft and shaft sleeve should be replaced.

Reasons for unstable operation of the sprinkler head include:

The installation position of the rocker arm is incorrect; the rocker arm spring is improperly adjusted or the rocker arm shaft is loose; the reverser fails or the rocker arm shaft is severely worn; the protrusion height of the reverser swing block is too low; the friction of the reverser is too great. The rocker arm height should be adjusted; the rocker arm spring should be adjusted or the rocker arm shaft should be tightened; the reverser spring or rocker arm shaft sleeve should be replaced; the swing block height should be adjusted; lubricating oil should be added to the swing block shaft.

Reasons for the small sprinkler head range and uneven spraying include:

The rocker arm striking frequency is too high; the rocker arm height is incorrect; the pressure is too low; the flow channel is clogged. 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; the blockage in the flow channel should be removed.
