The working principle of the cow milking machine
the cow milking machine as early as the beginning of our founding have begun to use, with the continuous development of science and technology, the performance of the cow milking machine and the using range has the very big enhancement, but, in the process of daily use, in order to understand the cow milking machine working principle and operation method, so as to better play to the machine's performance is, at the same time can also be in the right operation method under the guidance of ensure the safety of the cow milking machine and cows.
milking machine has two beat and three type two kinds. Around in the early 1950 s in China, we adopt three beats, presently adopted two beats type more. Its working principle is as follows:
1, 2 beats type so-called 2 beats, is when to start the milking machine, two beats in a beat. * * beat is sucking, at this time between the nipple and wall interior is vacuum, rubber set in a normal state. Because the nipple inside the tube and nipples chamber, the pressure difference between the papillary sphincter open, milk is sucked nipple chamber, and then flow into the milk bucket ( Or storage tank) 。
the second beat is pressed, the nipple chamber is still in the vacuum state, whereas in the wall between the indoor into the air, the rubber sleeve is compressed by the pressure differential between the two rooms, sphincter closed, milk stopped flowing. Crush the tempo is the purpose of to massage the nipples with squeezing method, to restore the sucking rhythm by suppression of nipple blood circulation.
2, three beat three beats milking machine besides sucking and squeezing two beats, also increased the third beat, the rest to the beat. It's easy to eliminate two beats type of milking machine faults. But milking speed slower. 3 in a pulsating rhythm of time is roughly: suck beat 45%, squeezing beat 15%, the rest 40% beat.
milking machine operation process
as well as manual milk, milk should also be in hot water before ( 50～55C) Scrub and massage a breast. Open the switch, switch on the power supply, make the motor rotation. Adjust the vacuum pressure gauge, the vacuum close to 30-35 cm, usually no more than 40 cm. Then thick rubber tube on the switch of the catheter, turn on the switch. Then hand clenched milk a cup of milk, milk open the switch on the lid with another hand, from the far side of the milk cup set on the nipples. Pulsator pulsation frequency general adjustment to 50-60 times/min. In milking process, through pipe is peer observation on milking machine milk flow conditions, such as no milk flow out of date, namely the milking barrel should be closed on the switch on the switch or catheter, gently remove the milk cup, hung on milking lid. New kind of milk cup can fall off automatically according to the milk flow situation.
every time, after finished milking pail and related parts in contact with the milk remove clean, first rinse with cold water, then use 85 ℃ hot water to wash. Method (is connected to main Crude rubber tube) Back, open the switch on the catheter, collection of milk, milk make a cup of water, milk and then open the lid on the switch, the water absorption into the milking stools, wash wash bucket again after breast milk cup and tube cover and barrel wall. Wash finish again with hot water washing, then put the milking machine hung on the rack to dry.
after understanding the working principle of the cow milking machine, according to certain procedures to correct the mechanization of operations, including prophase cleaning and massage the breast, the middle of the milk cup and sterilized nipples, and so on a series of operation process. Both milk can guarantee effective work, and can both safety and environmental hygiene.
