METHOD OF DETERMINING TECHNICAL CONDITION OF PULSATOR OF MILKING MACHINE Russian patent published in 2015 - IPC A01J7/00 A01J5/10 

FIELD: agriculture.

SUBSTANCE: pulsator is connected to a vacuum pump. The operating level of vacuum gauge pressure is set in accordance with the technical characteristics of the pulsator. The measuring means of the vacuum gauge pressure are connected to the working pipes of the pulsator. T vacuum gauge pressure is registered for a certain period of time with strokes of sucking P_s and compression P_comp. Then for the time T the average values P_s, P_comp are calculated, their mean-square deviations σ_s, σ_comp, the production tolerances for stroke of sucking δ_s=P_s±σ_sP_n±Δ and for compression stroke δ_comp=(P_s-σ_s)-(P_comp+σ_comp)>P_tcl are calculated, wherein the P_n is the standard value of vacuum pressure set by factory-manufacturer of the equipment, P_tcl is the value of vacuum of clamping the teat cup liner, Δ is allowable amount of change in the normative value of vacuum gauge pressure during milking. The coefficients of unevenness of change of vacuum gauge pressure at stroke of sucking are calculated ν_s=σ_s/P_s·100, the stroke of compression ν _comp=σ_comp/P_comp·100, the average value of the pulsation frequency of the vacuum gauge pressure is f=n/T, where n is the number of cycles of pulsation. The values obtained are compared with the set ones and according to the difference the technical condition of the milking machine pulsator is determined.

EFFECT: improved reliability of operation of equipment.
