The milking machine is one of the most important pieces of equipment on the dairy farm. There are five basic components of the milking machine: the vacuum pump, vacuum controller or regulator, pulsator, teat cup shell and teat cup liner or inflation. Other parts of the system such as the balance tank, lines, vacuum gauge, sanitary trap, etc. are accessories to these main components. In terms of farm energy consumption vacuum pumps represent one of the largest consumers of electrical energy.
Vacuum pumps
The function of the vacuum pump is to remove air from a closed system, thereby creating a partial vacuum and essentially ensuring a balance between the vacuum and airflow.
Most conventional milking systems are intentionally oversized so that they are capable of coping with the largest anticipated vacuum capacity. However in terms of energy savings, the key lies in maintaining and regulating a certain vacuum, making variable speed drive vacuum pumps a far better option.
Regular vacuum pumps run at full capacity while variable speed pumps modulate the speed and energy consumption to match the actual vacuum needed. The variable frequency drive (VFD) controller changes the motor speed of the vacuum pump in order to maintain the desired vacuum, offering the following benefits:
Reduced power use
Reduced maintenance and servicing
Reduced heat and noise
Increase in equipment life
Energy savings of up to 50%-60%
100% payback in 2-3 years.
Reliable as regular vacuum pumps
