Hydraulic cylinders are elements characterized by their simple design and durability. They require a minimum of maintenance. Nevertheless, under high loads and severe operating conditions, they fail and must be replaced. A new hydraulic cylinder will also be needed if there are visible signs of wear. Timely replacement is a guarantee of longevity and efficiency. You can sell your tractor for scrap at this company: https://scrap4cash.com/how-to-scrap-a-car-in-toronto/.
Key features and types
Hydraulic cylinders for the MTZ are volumetric engines that are actuated by the pressure created by pumping working fluid. Oil (or other compound, depending on the model) flows under pressure to the piston.
In tractors, hydraulic cylinders are used in:
– front and rear suspension cylinder groups;
– linkage equipment;
The number of hydraulic cylinders in the machine depends on the model, year of manufacture, and technical characteristics of the tractor.
The mechanisms have a number of advantages, including:
– high load capacity indicator;
– stability and safety during machine operation thanks to the rigidity of the part;
– simplicity of design;
– affordable price.
Hydraulic cylinders fail quite seldom. If the mechanism breaks, it does not require serious investment in the repair of equipment.
The design features of the hydraulic cylinder
It is a simple motor and consists of the following elements:
– front and rear covers;
– a rod with a spring;
Depending on the type and purpose of the hydraulic cylinder, there may be slight differences in design.
The following types of mechanisms are distinguished:
Piston hydraulic cylinders are single-acting and double-acting. Stroke length of the rod is determined by its strength. Usually it is not more than the sum of ten diameters of the main part. Single-acting elements are mainly used in the tractor control system, in the drive, and in some types of attachments. Double-acting parts provide maneuverability of machinery. Plunger and piston rod are located in the working planes.
Plunger hydraulic cylinders are reliable and less labor-intensive to produce, since they don’t have a piston. In addition, the inside of the body does not need to be machined “clean” because there is no chrome coating. The direction of movement is determined by a sleeve made of durable alloys. Plunger cylinders are only available as single-acting hydraulic cylinders.
The telescopic parts get their name from their striking resemblance to a spyglass. Their use is justified by the need for a large stroke of the piston rod. Two-way parts are available for MTZ.
When choosing, you should pay attention to:
– diameter of the inner sleeve;
– pressure rating;
– piston specifications;
– rod diameter.
No tractor model can be operated without hydraulic cylinders. They are necessary for effective manipulation of attachments, including lifters and moldboards. In addition, the part is one of the important components of the steering system.
Features of maintenance
The first thing worth remembering: under no circumstances should you repair hydraulic cylinders on your own. “Artisanal” method will help to save money, but only for the first time. After such “repair”, other parts often fail. Only specialists should diagnose, make a decision about repair or inspection of hydraulic cylinders. Not only special knowledge, but also tools are needed to perform the work.
