Milking machine MDU-7 and its other modifications help farmers to carry out automatic milking of a small number of cows. The equipment is mobile. The MDU lineup has minor design differences. Each unit is designed for a certain number of cows.
Features of milking machines for cows MDU
For a small household, the purchase of an expensive milking machine is not economically viable. It is difficult to assemble equipment on your own. Additional knowledge and experience are required. In addition, homemade products do not always work effectively, injuring the udder of the cow. The MDU lineup was created to facilitate the work of the owners of a small number of cattle livestock. Due to the wheels, the unit is easy to transport. The equipment is compact, lightweight, easy to maintain.
The most productive model is considered to be MDU 36. In households, machines are used, where after the letter abbreviation in the marking there are numbers from 2 to 8. Of the entire line, only the milking machine for cows MDU 5 is based on a dry principle of operation. Other models have a closed lubrication cycle. These devices are characterized by the minimum consumption of engine oil.
The MDU installation consists of the following units:
- Electrical engine;
- vacuum pump;
- starting device;
- fan or oil cooling system;
- collector;
- pressure regulator;
- pulsator.
Of the additional equipment, each unit is completed with hoses for transporting milk, a can. The containers are most often made of aluminum.
All MDU models are arranged and work according to the same principle:
- The pump creates a vacuum in the system, pumping the milk out of the teat cup body and transporting it through the hoses to the can.
- The pulsator periodically equalizes the pressure at the same frequency. From its drops, the rubber inserts inside the teat cups are compressed and unclenched. There is an imitation of nipple sucking with the lips of a calf.
Mechanical milking does not injure the udder of the animal. After filling the can with milk, the milkmaid pours it into a large container.
All MDU equipment is located on a solid steel frame made of lightweight profile. Before starting milking, the machine is placed on a horizontal, solid surface. In motors with a closed lubrication system, the oil level is maintained above the red mark.
Milking machine MDU-2
The equipment of MDU 2 has several modifications. The machines in this range are designed for milking cows and goats. The most popular is the milking machine MDU 2a, reviews of which are more often positive. Model 2a was designed for milking six cows.

The unit is completely assembled, after unpacking it is ready for use. Milking can be done near the cow or at a distance of up to 10 m.
The 2b model allows two cows to be connected at the same time. The device is equipped with a liquid ring pump with a 1.1 kW electric motor. Productivity - 20 cows per hour.
The 2k model is used for milking goats. One device is designed for 15 heads, but each animal is connected in turn.
Specifications
Installation MDU 2a has the following characteristics:
- electric motor power - 1.1 kW;
- connection to the 220 volt power grid;
- maximum productivity - 180 l / min;
- weight without packaging - 14 kg.
The manufacturer guarantees a service life of up to 10 years. The average cost is about 21 thousand rubles.
Instructions
When using the machine for the first time, the cows are taught to operate the engine. For several days in a row, the installation is simply started in idle mode. When the cows are no longer afraid of the noise, they try milking. The udder is thoroughly washed, massaged. Teat cups are put on the teats. The silicone suction cups should stick tightly to the udder. After starting the motor, operating pressure will build up in the system. The beginning of milking can be easily identified by the flowing milk in the transparent tubes. At the end of milking, the motor is turned off. Pressure is released from the system so that the glasses can be easily removed. It is impossible to tear off the suction cups by force, since the udder is easily injured.

Instructions
For the milking machine MDU 5, instructions are supplied by the manufacturer along with the equipment. The operating principle of an air-cooled plant is simple:
- A running motor evacuates air from the system. A vacuum is generated inside the hose. The pressure drop in the milk tubes is created by vacuum connections connected to the can lid. In addition, a vacuum is created in the pulsator and the hoses connected to the manifold and the teat cups.
- They put glasses on the nipples of the animal. The elastic insert wraps around them due to the created vacuum.
- A chamber is located between the insert and the wall of the glass, where a vacuum is similarly created. When the pulsator starts to work, the vacuum inside the chamber with a certain frequency begins to change to a pressure equal to atmospheric pressure. The rubber insert is compressed and unclenched, and with it the nipple. Milking begins.
Stopping the movement in the transparent milk tubes signals the end of the process. The motor is turned off. After equalizing the pressure in the system, the cups are removed from the udder of the cow.
