Irrigation Machine Working Principle

Irrigation Machine working principle

Round sprinkler is also the hourly sprinkler, is a large sprinkler irrigation, the main high degree of automation, to adapt to terrain strong, so often in large pastures, lawns, farmland can see its shadow. To say the working principle of circular sprinkler, the following will explain in detail.

Round sprinkler works:

The sprinkler is a fixed center point, the general center point by the four supporting angle through the anchor bolts or anchor chain fixed on the concrete base. The center point is the central rotation mechanism of the unit, and the 90 ° elbow at the bottom of the center point is the water supply of the circular sprinkler. The water flow is through the center point of the standpipe and the rotating elbow into the main pipe, and the rotary elbow utilizes a lip seal to prevent the pipe from leaking and to rotate inside the standpoint standpipe.

The main pipe will be piped to the end of the emitter - sprinkler, nozzle on the block for uniform spraying. Sprinkler equipment, the main pipeline is a series of cross-body connection made of cross-body is composed of the main pipe and truss group. The length of each cross-body can be adjusted by the increase or decrease of the main water supply pipe and the truss group. Each truss group provides a support force for the main pipe by connecting the truss frame by the truss and ensuring the strength of the cross-body force.

The cross-body connection is made by a ball-shaped bolt and a ball-headed head, which provides a lateral and vertical adjustment between the transports. Two cross-body water main pipes are connected together by a flexible rubber hose flexible joint.

Automatic sprinkler equipment components

1, water:

Sprinkler systems, like ground irrigation systems, must first have water. Rivers, canals, reservoirs, ponds, lakes, well springs and so can be used as sprinkler system water. Sprinkler irrigation in addition to the water must meet the water quality requirements, but also must meet the nozzle of the working pressure. When the spray irrigation water is higher than the irrigation area, and there is enough pressure difference, the use of natural water head, self-pressure irrigation. In addition, mechanical pressure must be used.

2, pressurized equipment:

Including pumps and power. Sprinkler system commonly used pumps have centrifugal pumps, self-priming centrifugal pumps, deep well submersible pumps. Power machine with electric motors, diesel engines, gasoline engines, but also commonly used tractor or tractor instead.

3, the pipeline system:

Sprinkler systems include pipes, standpacks and fittings. Pipes generally have a trunk, sub-trunk and branch pipe three, small works may only trunk and branch two levels. In order to avoid the impact of the nozzle spray nozzle, often in the branch pipe installed with standpipe nozzle, the length is generally 0.5 ~ 2.5m. In order to connect and control the piping system, the pipe is equipped with a certain size and quantity of pipe accessories, such as elbow, tee, four, all kinds of joints (telescopic joints, reducer joints, quick joints), various valves , Check valve) and safety protection devices.

4, nozzle

Sprinkler is a special equipment of the sprinkler equipment, is an important part of the sprinkler system, its role is to have a pressure of concentrated water flow through the nozzle nozzle spray out in the air or shatter the device under the action of the water will be dispersed into small water droplets , Evenly sprayed in the field.
