Method of regulating the vacuum level in a milking apparatus, and a milking apparatus

摘要

A milking apparatus includes a vacuum pump (1), a milking device (6) having at least one milking claw and teatcups (7, 12, 13) provided to be attached to an animal to be milked, and a conduit (5) connecting the milking claw and teatcups (7, 12, 13) to a suction side (2) of the vacuum pump and being adapted to transport a flow from the milking device (6). The vacuum pump (1) is of a dynamic type. Furthermore, a regulating device (22, 23, 24, 25) is adapted to maintain the vacuum level of the milking apparatus at a desired, constant value. Furthermore, the regulating device comprises a sensor (23) for sensing the actual vacuum level of the conduit (5) and a regulator adapted to control the vacuum level to the desired value by regulating the size of the flow through the conduit (5) and the vacuum pump (1) in response to the vacuum level sensed.
