The Use of a Magnetic Liquid Seal in the Design of an Electric Pulsator for a Milking Machine Manufactured Based on a Linear Electric Motor

Sustainable agricultural systems are a prospect for the development of the agricultural sector as a whole, including dairy farming. One of the main tasks of sustainable agriculture in this area is the creation of milking machines with intelligent modes of operation. Such longitudinal devices can be created on the basis of linear motors with a magnetofluidic seal. One example of their use is as a seal in an innovative design of an electro-pulse machine used in milking operations. By using a magnetic fluid in a sealing unit, it is possible to keep the shaft of a linear motor in place, preventing unwanted movement and vibration. This helps to ensure a more consistent and higher quality milking process. The researchers looked at different samples of magnetic fluid, each with a different concentration of solid particles, in order to better understand their magnetic and heat properties. The developed sealing unit can withstand significant pressure, as confirmed by theoretical calculations. The research into magnetic fluids has led to the determination of their key characteristics for use in magnetofluidic sealing units of an electropulsator, thus paving the way for their use in modern technical systems with a linear actuator.
