Hydraulics and electric accessories

The hydraulic and power systems have undergone a number of modifications, aimed first of all to improve the reliability and convenience of the harvester maintenance.

The power hydraulic pumps of three systems — principal, steering and undercarriage — are integrated into a single block of pump station. The hydraulic fluid is common for all systems and is filled up in one hydraulic tank. Besides the obvious convenience in service such conception has increased the reliability and maintainability of the equipment.

The distributive valves contain a lot of sections and are located on the readily available zones. All hydraulic system elements are delivered from the reliable enterprises, among them are the products of airline and defence enterprises.

The hydraulic systems processing technique have been changed. Now, all lines are exposed to a careful preliminary cleaning on the specially developed equipment to improve the internal surface cleanliness.

To ensure the hydraulic system maximal reliability, the soldered joints have been excluded, instead the line connections with the help of fitted rings have been adopted, the line layout has been also changed. Now the fluor-rubber seals, which have a lesser degree of shrinkage and are much more durable in comparison with the previous ones, are used. In place of cast sections for the hydraulic system accessories the stamped blanks are used.

As for electrical equipment, the absence of complicated electronic equipment, common to the harvesters of «Rostselmash», makes the maintenance very simple. The «Vector» electronic filling became even simpler and more reliably due to reduction of the elements quantity and the use of the new components from the best world manufacturers. New performance capabilities are added on the electronic control systems: the short-circuit and electric circuits integrity checking. For example, if the electric circuit to some sensor is damaged, the appropriate alarm statement will be displayed on the control panel. The accumulators are located more rationally — you can perform their maintenance directly from the soil.
