A dashpot timer is a container, a piston, and a shaft. The dashpot timer functions when a magnetic field forces a piston to move within a cylinder when the coil is energized. The movement of the piston is limited by fluid passing through an orifice on the piston. The amount of fluid passing through the orifice is controlled by a throttle value ...
Pulse drip irrigation is an experimental irrigation technique primarily used with drip irrigation. Maintaining a high level of soil moisture for germination of seed is one reason this technique may be used. Most conventional drip irrigation systems can be made to pulse by using a timer to reduce the watering duration and increase the watering ...
In the early 1930s, a farmer drew his attention to a big tree, growing in his backyard "without water". After digging below the apparently dry surface, Simcha Blass discovered why: water from a leaking coupling was causing a small wet area on the surface, while an expanding onion-shaped area of underground water was reaching the roots of this particular tree—and not the others.
An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or medium between the emitter and cool ...
Drip irrigation. Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
Water heaters that instantly heat water as it flows through the device. The inside of a hydraulically operated two-stage tankless heater, heated by single-phase electric power. The copper tank contains heating elements with 7.2 kW maximum power. Tankless water heaters — also called instantaneous, continuous flow, inline, flash, on-demand, or ...
An irrigation sprinkler (also known as a water sprinkler or simply a sprinkler) is a device used to irrigate (water) agricultural crops, lawns, landscapes, golf courses, and other areas. They are also used for cooling and for the control of airborne dust. [citation needed] Sprinkler irrigation is the method of applying water in a controlled ...
A water timer is an electromechanical device that, when placed on a water line, increases or decreases the water flow through the use of an electro-mechanically actuated ball valve or embedded (solenoid) valve. It is used in conjunction with irrigation sprinklers to form an automated or non-automated sprinkler system, capable of administering ...
