1, the degree of vacuum can not meet the requirements. When starting and working, if the vacuum meter reading is not in the range of 45 to 50 kPa, the reason may be that the vacuum tank seal leaks. The inspection method is to use colored water on the seal to observe whether the color penetrates into the tank. Yes, it means that 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 observe the reading of the vacuum gauge while turning the copper bushing of the regulator until the pointer is within the normal range, and then lock the nut. Tighten.
2. There is no vacuum inside the milk tank and there is a vacuum in 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. The milk tank and various parts should be cleaned.
3, pulsator does not work. There are four reasons: First, the vacuum tube switch does not open, should be opened; Second, the pulsation frequency adjustment screw screw in the end, should be transferred to the appropriate position; Third, there is a skew between the pulsator cover and the body, should be adjusted; The fourth is that the vents of the pulsator are blocked and should be dredged.
In short, normal maintenance of the milking machine and the timely elimination of failures can not only extend the life of the milking machine, but also avoid unnecessary economic losses. The farmers should pay sufficient attention to it.
