Impact Sprinklers
An impact sprinkler, sometimes referred to as an impulse sprinkler, is a type of irrigation sprinkler widely used for watering crops, lawns, gardens, and other landscapes. Its unique design allows it to rotate and emit a stream of water in a circular pattern, ensuring even distribution across the covered area.
History and Development
The impact sprinkler was invented in 1933 and later became popular due to its innovative mechanism. The invention of the impact sprinkler is an important milestone in the timeline of agricultural advancements in the United States, particularly in the period from 1890 to 1945. This device revolutionized irrigation practices, offering a reliable and efficient alternative to traditional surface irrigation methods.
Design and Functionality
Impact sprinklers are known for their rotating sprinkler head, which is driven by the force of water. The head pivots on a bearing on top of its threaded stem, allowing it to rotate as water flows through. This rotation is powered by a hammer mechanism that uses the water pressure to move the sprinkler's nozzle in a circular motion.
The design of the impact sprinkler often includes materials such as brass, stainless steel, and plastic, ensuring durability and resistance to various weather conditions. The sprinkler is adaptable to low-pressure and low-gallonage irrigation systems, providing coverage up to 4,070 square feet.
Features and Variants
Impact sprinklers come in several variants, including the Rain Bird Maxi Paw, which combines the traditional impact sprinkler design with a pop-up mechanism. This feature is particularly beneficial for close-in watering and maintaining uniform water distribution. The Maxi Paw is equipped with a stainless steel spring that retracts after watering, ensuring a positive pop-up action.
A notable feature of some impact sprinklers is the brass-weighted PJ spray guiding arm, which provides superior control over the water stream and prevents side splashes onto buildings and walkways. Non-potable impact sprinklers are often marked with a purple cap for easy identification.
Applications
Impact sprinklers are versatile and can be used in a variety of settings, from residential lawns to large agricultural fields. Their design caters to the needs of different environments, making them suitable for both small gardens and extensive farming operations.
The Rain Bird company, associated with the development of this sprinkler type, played a significant role in popularizing its commercial use. Rain Bird's impact sprinklers are renowned for their efficiency and reliability, making them a preferred choice for irrigation across the globe.
