1. The degree of vacuum does not meet the requirements. When starting and working, if the vacuum gauge reading is not in the range of 45 ~ 50 kPa, the reason may be that the vacuum tank seal is leaking. The inspection method is to apply colored water to the seal to observe whether the color penetrates into the tank. Yes, the seal needs to be replaced. If there is no color infiltration, the regulator may be loose. Open the top cover of the regulator and turn the copper sleeve of the regulator while observing the reading of the vacuum gauge until the pointer is within the normal range, then lock the nut. Tighten.
2. There is no vacuum in the milk bucket and there is a vacuum inside the tube, but it cannot be squeezed. The reason for this is that the lid is not clean, causing the single valve to adhere to the seat. At this time, the milk bucket and each part should be cleaned.
3. The pulsator does not work. There are four reasons for this: one is that the vacuum conduit switch is not open and should be opened; the other is that the pulsation frequency adjustment screw is screwed to the end and should be adjusted to the appropriate position; the third is that the pulsator cover and the body are skewed and should be adjusted; Fourth, the vent of the pulsator is blocked and should be unblocked.
In short, the normal maintenance of the milking machine and the timely elimination of the failure can not only prolong the service life of the milking machine, but also avoid unnecessary economic losses, and the farmers should pay sufficient attention.
