To make required decompression level in the milking system in order to make required decompression level

摘要

The invention relates to a method in a milking system for creating a required vacuum level, the milking system comprising at least two variable speed vacuum pumps P1, P2. The method comprises the steps of: utilizing a first variable speed vacuum pump P1 for creating the required vacuum level within the milking system; monitoring the vacuum level requirement within the milking system, and when the vacuum level requirement of the milking system is such that the speed of the first variable speed vacuum pump P1 reaches a first speed threshold then: starting a second variable speed vacuum pump P2, and running the first and second variable speed vacuum pumps P1, P2 in parallel for creating the required vacuum level. The invention also relates to computer program products.
