The AID-2 milking machine, as well as its analogue AID-1, have a similar design. Some characteristics and equipment differ. The equipment has proven itself on the positive side and is in demand in private households and small farms.
Advantages and disadvantages of milking machines for AID cows
Each AID milking machine has its pros and cons. It is reasonable to consider each model separately.
Advantages of AID-2:
- the presence of a dry type vacuum pump;
- the equipment is suitable for work in any conditions where the air temperature does not drop below + 5 OWITH;
- well-fitting elastic suction cups on the glasses do not injure the udder and nipples;
- two animals can be connected to the milking machine at the same time;
- Light weight and the presence of a trolley with wheels make the device mobile.
The disadvantage is poor ventilation of the channels for transporting milk.A working device consumes a lot of air.
Advantages of AID-1:
- The rubber coupling smoothes out vibrations of the running engine, which extends the service life of the equipment and reduces noise levels.
- Thanks to the increased size, the receiver takes a long time to fill with milk. In the event of a can overturning or another emergency situation, the device will have time to turn off before the milk is lost.
- The accessible location of the units allows for easy maintenance.
- Large diameter wheels make it easy to transport equipment on a cart.
The disadvantages of AID-1 are similar to those of the AID-2 model.
Milking machine for cows AID-2
The developer of the milking machine is Korntai LLC. The Ukrainian enterprise is located in Kharkov. The model was created to increase productivity and quality of milking. According to its characteristics, the AID-2 milking machine is designed to serve 20 cows.
The operation of the milking machine is based on the creation of vacuum oscillations in the system. Due to the ongoing processes, the nipples of the animal's udder are compressed and unclenched. From the actions taking place, milk begins to be milked, which is transported from the teat cups through milk hoses into the container. In essence, the operation of the vacuum system closely mimics the actual suckling process of a calf. The cow's teats are not subject to injury. Full expression of milk prevents mastitis from developing.

How to assemble the AID-2 milking machine
The main components of the AID-2 device are supplied from the factory in assembled condition. All components will have to be installed independently. In essence, there are two units to be assembled: a vacuum-creating device and a milking system consisting of a can and attachments.
The step-by-step process of assembling the AID-2 milking machine consists of the following steps:
- The milking cups are collected first and connected to the collector. It is important to maintain a distance of about 7 mm on the glasses between the edge of the nipple cup and the ring. The thin edge of the milk hose is inserted into the nipple suction cup. The pipe is gradually pulled out so that the thickening on it is clamped by a ring mounted on the nipple suction cup. Milk hoses with connected nipple suction cups are placed inside the teat cups, leading the pipe out through the hole. The elastic rubber insert should stretch inside the glass body.
- The assembly of the milk can of the AID-2 apparatus begins by connecting the hose. The container lid is equipped with three holes. A hose leading to a vacuum cylinder is connected to the first one. A hose is connected to the second one, the second end of which is put on the plastic fitting of the manifold.The third hole is used to connect a unit consisting of a pulsator, the hose from which is connected to another output of the manifold to a metal fitting.
- The last step is to install a vacuum gauge on the cylinder. The device determines the working pressure.
- The can is installed on a trolley where all the components of the apparatus are located. Check functionality.
Before putting the teat cups on the teats, set the vacuum depth values specified in the instructions. The manifold valve is closed. The glasses are placed on the nipples one by one. The milking process begins. At the end of the procedure, the manifold valve is opened. In a similar sequence, the glasses are removed from the nipples one by one.
Instructions for the milking machine AID-2
In addition to the order of assembly and commissioning, the instructions for the AID-2 device contain instructions for proper installation and cleaning. The main requirement is to keep the milking machine as far as possible from the animal so that the noise of the motor does not cause fright. For a vacuum valve with a regulator, choose a place on the wall of the stall. The operator must reach the unit if necessary.
At the end of the work, the milking machine is cleaned. A special place is allocated for the procedure, where a large tank with clean water is installed. You can use a used cast iron or metal bathtub. Equipment is washed in the tank.
During washing, milking cups are placed in a bath with a detergent solution. When the pulsator is turned on, flushing of the system begins.After the solution, clean water is distilled. Wash the milk can separately. Clean equipment is left in the shade to dry.
Malfunctions of the AID-2 milking machine
AID-2 milking machines are considered reliable equipment, but any equipment eventually malfunctions and breaks down. The most common faults are:
- The reason for the drop in pressure in the system is its depressurization. The problem is a violation of the integrity of hoses, connecting elements, clamps, which leads to air suction. The vulnerable spot is found by visual inspection and the fault is eliminated.
- A common problem with AID-2 is the malfunction of the pulsator. The node does not work completely or there are interruptions. The first cause of breakdown is contamination. The assembly is completely disassembled, thoroughly washed and dried well. If the pulsator parts are wet, interruptions in operation will occur again. During washing, it is important to examine each part and determine the degree of wear and damage. Items unusable for use are replaced.
- The problem of air leaks is associated with wear of rubber elements and vacuum hoses. Faulty components are replaced. Check the strength of the connections.
- The engine may not turn on for many reasons. First of all, check the serviceability of the power cord, the start button, the absence of malfunctions of the vacuum pump, and measure the voltage in the network. If the search does not lead to positive results, the cause of the malfunction may be the stator winding. The repair is complex, and only service technicians can perform it.
Despite the large list of malfunctions, they rarely occur in AID-2 devices.Milking machines are characterized by reliability, trouble-free operation, subject to operating rules.
