Productive and uninterrupted operation of the chemical, oil, geological exploration and other sectors of the national economy of the Republic of Kazakhstan directly depend on the quality of work of units and assemblies of technological equipment, in particular, from hydraulic drives and hydraulic machines. The development of the chemical technology of oil and gas cannot be carried out without the improvement and automation of technological equipment, mechanisms and assemblies, which are accompanied by continuous improvement of their design and the degree of use of hydraulic devices in them. The main units of each volumetric hydraulic transmission used in the chemical technology of oil and gas are hydraulic pumps, gear pumps (GP). An extended study was conducted to determine the main causes of premature failures of gear pumps associated with breakage and wear of parts. The results of the survey showed thatwear and breakage of parts occur in the initial stage of operation of the gear pumps. The reason for this may be the imperfection of the pump design, poor quality assembly and machining of parts. The authors propose a “biaxial connection” based on the theory, which will change the design, technology of mechanical processing and assembly of parts and assemblies of gear pumps. The use of a biaxial connection in the gear pump design led to a change in the design of the support bushings and the system for setting their dimensions. It is established that partial restriction of relative movements of individual parts of the gear pump leads to an increase in quality indicators. The research was carried out within the framework of the grant №AP09562459.
