What is sprinkler irrigation equipment

Views:2     Author:Site Editor     Publish Time: 2019-08-13      Origin:Site

The sprinkler irrigation equipment will spray water into the air through the nozzles, and it will be raindrops scattered on the fields and crops on the farmland irrigation equipment. The irrigation water can be pressurized by a water pump, or it can take advantage of the natural drop of a high water source. The sprinkler irrigation equipment pressurized by the water pump includes the power machine, the water pump, the water supply pipe and the nozzle; the sprinkler irrigation device that uses the natural drop can be used without the power machine and the water pump.

Sprinkler composition

Irrigation facilities consisting of irrigation water sources, sprinkler irrigation equipment and field projects are called sprinkler irrigation systems. Sprinkler irrigation equipment usually consists of three parts: water supply machinery, water supply pipeline and nozzle. It is divided into fixed, semi-fixed and mobile according to the installation and mobility of the components. The fixed sprinkler irrigation equipment is fixed and the water supply machinery is placed at the water source. The main pipe and branch pipe of the water pipeline are generally buried in the ground, and the vertical pipe is installed on the branch pipe at a certain distance, and the nozzle is screwed on the vertical pipe. When sprinkling, all nozzles can be turned on or turned on in sections. According to the operation requirements, the nozzle can be sprayed in a circular or fan shape. The branch pipe of the semi-fixed sprinkler system can be moved and connected to a reserved valve on the main pipe as needed. Mobile devices are mobile.

Sprinkler

The whole unit consists of a water pump, a power machine, a water pipeline, a nozzle and its supporting parts. It is divided into self-propelled, mechanically mobile and manual mobile according to its movement mode. According to the operation mode, the point sprinkler type and continuous sprinkler type are divided. The continuous sprinkling type of water is evenly distributed, and the moving speed can be adjusted, that is, the amount of water can be changed. The water distribution of the fixed-point sprinkler irrigation is not uniform enough. The sprinkler is divided into two types according to the number of nozzles: single nozzle and multiple nozzle. According to the size of the power, it is divided into light (3 to 6 horsepower), small (10 to 12 horsepower), medium (28 to 40 horsepower) and large (54 horsepower or more).


Nozzle


The function of the nozzle is to spray a stream of pressurized water into the air, dispersing fine water droplets and evenly spreading it over the irrigated area it is exposed to. The nozzle with good performance, in addition to the simple and reliable operation of the structure, must have appropriate sprinkling intensity and atomization degree, reasonable water distribution and low energy consumption. The nozzle can be divided into a low pressure nozzle (near-range nozzle), a medium pressure nozzle (medium range nozzle) and a high pressure nozzle (long-range nozzle) according to its working pressure and range. According to its structural characteristics and working characteristics, it can be divided into fixed and rotary. Rotary nozzles are also known as jet nozzles. It is to make the pressurized water flow through the nozzle and the nozzle to form a concentrated jet, and at the same time, the driving mechanism rotates the nozzle around the vertical axis. Under the action of the air resistance and the pulverizing mechanism, the jet is pulverized into fine water droplets and sprayed on the nozzle. Around it, a circular or fan-shaped sprinkling area with a radius of the range is formed. According to the way of driving the nozzle, it is divided into three types: reaction type, impeller type and rocker type. The most common application in forestry is the rocker-type nozzle. The fixed nozzle is also called a water-spraying nozzle or a diffusing nozzle. When the nozzle is sprayed, all the components of the nozzle are fixed, and the sprayed water is sprinkled radially outward, and the wetted area is round or fan-shaped. It has a smaller range than a rotary nozzle and is typically only 5 to 10 meters. The degree of atomization is high, the structure is simple, the work is reliable, and it is mostly used in greenhouses, vegetable fields and parks. The fixed nozzle is installed on the spray-type sprinkler, which not only improves the spraying quality, but also saves energy. It is suitable for the sprinkling irrigation of small seeds in forestry nursery.
