Watt Pipe Industry invites you to learn about reel-type sprinkler systems. In recent years, some regions have experienced severe droughts with minimal rainfall, leading to the drying up of many canals and insufficient water resources. As a result, irrigation has become challenging for certain agricultural fields. Fortunately, China has developed and produced reel-type sprinkler machines that excel in water-efficient irrigation and offer significant advantages in conserving water. These machines are now widely used in arid areas. Below, we’ll introduce the working principle and key benefits of reel-type sprinkler systems. ### What Is a Sprinkler System? A sprinkler system is an irrigation device that winds a PE irrigation hose onto a winch. It uses pressurized water from the sprinkler system to drive a water turbine, which then rotates the winch via a gear mechanism. This motion automatically moves the sprinkler carriage forward while simultaneously spraying water across the field. ### How Reel-Type Sprinkler Systems Work The reel-type sprinkler system operates on a unique mechanism driven by an expandable rubber capsule. When high-pressure water flows through the system after passing through a pump, part of the water enters a filter before reaching a rubber valve. The pressure forces the rubber valve into a closed position, causing the expandable capsule to swell fully. This expansion pushes against the hydraulic motor arm, which in turn engages with the rack-and-pinion system mounted along the edge of the reel, initiating its rotation. As the hydraulic motor arm compresses the expandable capsule, the spring inside applies continuous pressure, keeping the rubber valve open. Meanwhile, the water escaping from the capsule exits through a regulator-controlled outlet. A secondary passive pin on the reel’s rack-and-pinion system ensures that the reel rotates only in one direction—preventing reverse movement. This continuous, controlled rotation allows the system to unwind the hose efficiently, enabling seamless irrigation across the field. ### Advantages of Reel-Type Sprinkler Systems 1. **Uniform Irrigation:** This system delivers water evenly across the field, promoting optimal crop growth and improving both yield and quality. Farmers can precisely adjust water distribution based on the size of their land, ensuring crops receive exactly what they need. Additionally, the use of high-pressure nozzles creates fine water droplets that enhance humidity levels and create a more favorable microclimate, boosting crop quality while minimizing fertilizer and water runoff—leading to higher productivity. 2. **Water Conservation:** Compared to traditional flood or furrow irrigation methods, this system significantly reduces water usage. For instance, when irrigating at 30 mm of rainfall, it requires only about 20 liters of water per mu—just 1/5th the amount needed for conventional flooding and 1/3rd of what’s required for low-pressure pipe irrigation. This makes it a highly effective solution for conserving precious water resources. 3. **Versatility Across Landscapes:** Reel-type sprinkler systems are suitable for fields of varying sizes, shapes, and topographical conditions, including those with steep slopes. They can effectively irrigate both tall-stemmed and short-stemmed crops such as corn, soybeans, wheat, and potatoes. Moreover, these systems are ideal for fruit trees, sugarcane, tea plants, bananas, and other specialty crops. Perhaps most notably, these systems are cost-effective and adaptable to uneven terrain. They simplify irrigation tasks, saving time and labor compared to traditional methods. On average, users can cut irrigation costs by nearly 50% compared to conventional techniques. Since their introduction, these systems have played a crucial role in helping farmers achieve bountiful harvests even during severe droughts, delivering remarkable economic benefits. ### Important Considerations When Using Reel-Type Sprinkler Systems 1. **Wide Operational Space Required:** Reel-type sprinkler systems typically require a wide operating path—usually between 3 to 4 meters—occupying considerable space. 2. **Smooth Road Surfaces Are Essential:** When the system is moving over uneven or rough terrain, the water-filled hoses can easily suffer wear and tear. Therefore, it’s critical to ensure that the pathways carrying the water pipes remain smooth and free of obstacles. 3. **Sensitivity to Wind Conditions:** Higher wind speeds can disrupt the uniformity of water distribution. To avoid this issue, it’s best to limit operation during windy days or reduce the spray intensity accordingly. 4. **Soil Compatibility:** Avoid using reel-type sprinkler systems on soils that are excessively clayey or heavy.

The reel-type sprinkler irrigation system is ideal for irrigating large areas of farmland, as it allows users to precisely control the amount of water sprayed through adjustable nozzles, catering to varying irrigation needs. This makes it a perfect choice for water-saving irrigation in agricultural settings. Additionally, the system is well-suited for applications requiring both irrigation and dust suppression—such as power plants, ports, sports fields, and urban green spaces. The system features a water-turbine-powered drive mechanism, enabling high recovery speeds even at very low flow rates, which facilitates the automatic retraction of PE pipes. Meanwhile, the high-pressure water discharged from the turbine flows through the PE pipes directly to the sprinkler heads, where it’s evenly dispersed into fine droplets that gently fall over the crops. As the PE pipe moves, the sprinkler system delivers a continuous, uninterrupted spray across the entire field. ### Application of Reel-Type Sprinklers in Field Crops In China, agricultural irrigation accounts for 70%–80% of total water consumption, with field crops like wheat, corn, and sweet potatoes consuming 50%–60% of this irrigation water. Therefore, prioritizing water conservation efforts on field crops is crucial. Currently, the primary irrigation methods for these crops include pipeline irrigation and canal irrigation, with canal irrigation still dominating due to its widespread adoption. While pipeline irrigation represents a significant step forward in water efficiency compared to traditional canal systems, it only improves the overall water-use efficiency of the distribution network—not the actual field-level efficiency. On the other hand, fixed sprinkler systems, though highly effective in conserving water, have struggled to gain widespread adoption because they don’t align well with conventional farming practices. Similarly, semi-fixed and mobile sprinkler systems face challenges related to operational complexity and maintenance, limiting their scalability. To address the need for efficient, large-scale irrigation solutions for field crops, our company has introduced cutting-edge international sprinkler technology and developed a new generation of reel-type sprinkler machines tailored specifically for field crop irrigation. These innovative systems have already demonstrated remarkable success in improving both water efficiency and crop yields. ### Proven Benefits of Reel-Type Sprinklers Since being deployed, these reel-type sprinkler systems have played a vital role in ensuring bountiful harvests even during severe drought conditions, delivering impressive economic returns: - **Water Savings**: Compared to traditional canal irrigation, the system saves up to 47% of water; when contrasted with pipeline irrigation, it reduces water usage by 9%. - **Increased Yields**: Yield improvements reach as high as 25% compared to canal irrigation and 6% higher than pipeline irrigation. - **Energy Efficiency**: The system consumes over 70% less energy than conventional irrigation methods. - **Labor and Time Savings**: Operation is straightforward, allowing a single operator to manage up to six machines simultaneously.

The development of irrigation technology began in the late 19th century, with fixed, self-pressurized pipeline sprinkler systems first being used in the United States and Russia. Between 1913 and 1920, simple mobile sprinkler carts emerged, initially designed for grasslands, vegetable gardens, nurseries, and orchards. In 1922, the Soviet Union developed automatic rotating spray nozzles and long-range sprinkler equipment. By the 1930s, double-arm sprinkler machines and plastic pipelines had already been introduced. During the 1940s, oscillating-arm nozzles, quick-connect fittings, and aluminum alloy pipes started to appear, while end-drag and roll-type sprinkler systems gained traction in the U.S. Meanwhile, in the 1950s, the U.S. pioneered the development and production of hydraulically powered circular sprinkler systems.

I. Enhancing Salt Tolerance in Saline-Alkali Soils During crop growth, plants exhibit selective nutrient uptake. With the advancement of agriculture in China, while the issue of soil salinization remains particularly severe in the northwest region, secondary salinization has also emerged in southern areas—primarily due to the long-term overuse of chemical fertilizers. Moreover, if drought conditions occur between irrigation cycles, the salt concentration in the soil continues to rise, making it increasingly difficult for crops to absorb water from the soil and leading to a range of symptoms associated with salt stress. II. Saving Water and Energy While Boosting Fertilizer and Pesticide Efficiency In southern regions, where water resources are abundant, this challenge may not be as noticeable. However, in many northern areas, grape growers are already grappling with severe water scarcity, which further exacerbates the difficulties faced by agricultural practices.
