Abstract

The article is aimed at solving the problem of reducing energy losses in transmission units of lifting installations for well repair. The main directions for reducing the energy consumption of hoists for repairing wells were analyzed. The analysis of features of a design of transmissions of lifting installations for repair of wells is carried out. Studies of viscosity-temperature characteristics of modern transmission oils and temperature regime in transmission units have been performed. A method of rapid heating and maintaining the optimal temperature in the transmission units of lifting units by using the heat of the exhaust gases was proposed. A typical mechanical transmission of a hoisting installation for repairing wells on a wheeled chassis has been studied. The technique and means of experimental researches of energy efficiency of transmissions of lifting installations are resulted. Experimental studies of the implementation of the proposed method of reducing energy losses in transmission units. The dependence of the change in the temperature of the transmission oil in the gearbox at different modes of rotation of the primary shaft of the gearbox. The optimum thermal mode of operation of units of mechanical transmission of lifting installations by the manufacturer is not established in rigid frameworks. The determining factor is the efficiency of the oil under certain conditions. The dependence of power losses in the gearbox of the lifting unit of the UPA 60 / 80A model depending on the temperature and grade of transmission oil is obtained. The results of calculations of fuel consumption in the gearbox of the lifting unit of the UPA 60 / 80A model with different power drives and at different temperatures of transmission oil are given.

Key words: lifting installation for well repair, oil and gas technological transport; diesel engine; transmission unit; gearbox; heat utilization; exhaust gases; power; specific fuel consumption.
