Adaptive technical equipping of rural commodity producers

Lipkovich E.I.

Abstract

The purpose of this work was to study: interrelation of different levels of technical equipping concerning agricultural enterprises in which various groups of agricultural population are occupied; influences of technical equipping characteristics and some environment factors on the base technologies and their groups in agricultural works. Expenditure of energy by the operator at work in social production and in personal subsidiary plot are determined. Advantages of one-stage technologies of harvesting with green manuring or soil preprocessing are shown. The possibility of using one-stage technologies on the basis of new high-efficiency combine harvester RSM-181 with axial-rotor thresher is proved. Base technological complexes of machines concerning all five groups of rural commodity producers are constructed.

An innovation in the construction of water vaporizing air coolers for tractor cabs

Mikhaylov V.A., Sharipova N.N.

Abstract

The two-stage water vaporizing air coolers are suggested in two editions. These constructions are made in separated pattern: first (main) unit is a package of sequentially disposed air-to-water heat exchanger and irrigated by water packing, second (auxiliary) unit is a tower-cooler for cooling water in the air-to-water heat exchanger of first unit. The tower-cooler consist of irrigated packing in first edition of construction, second edition has a block of air conditioning. The introduction of two-stage water vaporizing air coolers is alternative of freon air-conditioner using, whereas benefit of energy efficiency is demonstrably.

Optimization of amplification factor of adaptive friction couplings with differentiated friction pairs

Shishkariov M.P.

Abstract

An operating mode of adaptive friction couplings of first generation with differentiated friction pairs is considered at the magnitude of feedback gain that surpasses the limiting value. It is shown that there is an amplification factor at which the exactitude of functioning of adaptive friction couplings raises. For the couplings of mentioned class a model of amplification factor optimisation is discovered.
