Why are diagrams needed?

Schemes of the tractor "BELARUS-1221" are a color medium that allows you to assemble electrical equipment and other components of the tractor - gearbox, PTO, transmission, engine, steering, hydraulic system, crank mechanism, etc. For mechanics working with this tractor , it is necessary to accurately present information in diagrams and descriptions of equipment control systems.

In order to be able to read a diagram correctly, you need to know that according to GOST 2.701, diagrams are assigned letter designations that help you understand which system the information contained in it belongs to. Conventional graphic symbols of elements and devices are performed in a combined or spaced manner, depending on how they are located in the system. Lines usually connect graphic images on a diagram; if this is difficult, then the line is interrupted and ended with an arrow indicating the name of the line. The diagram may separately indicate a functional group, which is a set of elements that perform certain functions in a product and are not combined into a single structure. Typically, such information is highlighted with a larger and free-standing image.

A correctly constructed technological process is the key to a correctly constructed diagram. Assembly, disassembly, attachment of parts and all necessary operations for putting equipment into operation occur according to a pre-drawn plan. If a mistake is made during the work, it will in turn harm the entire process of repairing the machine.

Beltract.Ru provides all the necessary diagrams for disassembling and assembling the systems of the BELARUS-1221 tractor, thereby helping to carry out work on the machine clearly and smoothly.

What is an MTZ electrical circuit?

Let's look at what the electrical equipment diagram of a Minsk tractor consists of. One of the advantages of Minsk technology is the use of high-quality electrical wiring, based on the fact that metal parts are designed to act as mass. The advantages of such electrical wiring MTZ-1221, 80 or 82 include:

But you need to take into account that wiring requires constant care and monitoring.

This will help monitor the serviceability of the wires, their insulation, and the reliability of the fastenings. If damage to the electrical circuit of the MTZ-80 or 1221 tractor is not detected in time, a fire, insulation damage, failure of electrical circuits, etc. may occur.

Let's look at the electrical equipment of Belarus tractors and a description of its operation.

The electrical circuit of MTZ-1221, 80 or 82 has the following characteristics:

• It has a polyvinyl chloride colored surface with low voltage.
• Additional elements are connecting panels, connectors, and wires that can be mounted in bundles. For example, such a half-move is applied to wires in MTZ-82.
• The PS 300A-100 socket is located on the rear wall of the operator's cabin and has 7 contacts.
• The socket is intended for all work where electricity is needed, including when transporting goods.
• Connection to the socket is made via a plug.
• If the need arises, you can connect the wiring harness from other units. Both the plug and the socket have special markings that help you understand where the wires are connected.

Thus, the wiring of MTZ-80, 82 and 1221 is functional and is designed to withstand loads while the tractor is operating.

"Belarus" MTZ-82.1 is a new universal agricultural tractor of 2006, which is a modified model of MTZ-82 and can be equipped with a hole drill, hay thrower or plow. In models produced since 2013, the chassis has been improved and a large number of attachments have been added, which can be purchased separately.

When performing electrical equipment maintenance or repairs, most often the required unit is removed or the wiring is partially disconnected; this is where you will need a schematic diagram of the electrical wiring in color, which you can view and download absolutely free!

If you need to disconnect or connect electrical wiring, repair equipment (for example, a generator or battery):

• check the electrical diagram;
• turn off the main switch before starting work (disconnection and connection of plugs should be carried out strictly when the engine is not running);
• do not check the serviceability of electrical circuits using the “spark” method, creating a short circuit;
• Observe the polarity of the battery, carefully connect plus to plus, minus to minus.

Starter in the tractor electrical circuit

A mandatory element of the electrical equipment of Minsk tractors is a starter, which is activated by a color scheme. The starter consists of the following elements:

• Electrical engine;
• drive unit;
• relay;
• switch.

Engine power is 4.8 hp. The MTZ-82 electrical circuit ensures the operation of a starter DC motor, which is made of series excitation coils. All coils have 4 poles.

To turn on the starter, the developers installed a special switch. It is located on the control panel in the operator's cab. The engine starts due to the fact that power comes from the battery. The torque from the shaft is gradually transmitted to the crankshaft, which is associated with the operation of the drive gear with the flywheel.

Design, types and applicability of FDA drive hydraulic valves

The hydraulic valves used in Belarus tractors are designed quite simply. They consist of a spool-type solenoid valve and a block in which a vertical channel is machined for the spool, as well as inlet and outlet channels. The spool can have two positions:

• Spool lowered - in this position, the spool closes the drain channel, but connects the inlet and outlet channels, so oil from the pump enters the fluid coupling; • Spool raised - in this position, the spool closes the inlet channel, but connects the outlet and drain channels, so the oil from the fluid coupling goes to the drain.

The solenoid valve is controlled using a button located on the remote control in the cab. To connect the valve winding to the electrical circuit, a connector (plug) is provided on the hydraulic distributor body. The hydraulic distributor is mounted on the gearbox cover using four bolts; for this purpose, four through holes are provided in its body.

Today, tractors Belarus-1221, 1532 and others use hydraulic valves of three types:

• Series RH06101-012 (manufactured by BADESHTNOST, Bulgaria); • Series 1РГЭ-6Т (manufactured in Gomel, Republic of Belarus); • MRE6-T574 series (manufactured by DUET Gidravlik LLC, Yaroslavl).

All hydraulic valves have an identical design and characteristics, that is, they are analogues of each other, and therefore can be used on Belarus-1221 and 1532 tractors without any restrictions.

Electrical circuit maintenance

Maintenance of the tractor circuit can be done with your own hands or with the help of an electrician. The main thing is that this happens regularly and that all terminals and fastenings are checked. If necessary, it is necessary to clean the necessary parts from dirt and dust.

The starter requires cleaning every 3000 hours of use. To do this you need to do the following:

• dismantle the starter;
• remove dirt;
• remove the casing that performs protective functions;
• check the brush-commutator assembly.

Then the starter must be reassembled and the insulation on the wires, the connections on the plugs, and the integrity of the wires checked.
