Organization and development of working instructions for maintenance of pumps of LLP «JV KazGerMunai»

Abstract

The scientific article contains working instructional documents on the organization of maintenance of existing types of pumps at the oil field of LLP «JV Kazgermunai», consideration of their optimal ways and maintenance with the participation of specialists in the main types of pumps. A schedule of preliminary planning of pump maintenance works at the oil field has been drawn up and the term of pump maintenance for the current year has been approved. The main purpose of the scientific article is the formation of a system of uninterrupted operation at the enterprise with optimization of maintenance in order to form a stable functioning of pumps at the oil field is to reduce the volume of basic costs for pump repairs and increase production volumes at the oil field. The scientific article discusses maintenance work on 4 types of pumps at the oil field of LLP «JV Kazgermunai». The article presents the values of the failure rate for modern brands of pumps of four groups: submersible, for drainage and wastewater; domestic; cantilever; underwater - for obtaining artesian waters based on statistical processing of data on their operation. Having developed analytical and statistical models for assessing their reliability at the enterprise, the types of failures during their operation and their probabilities were determined. Information on malfunctions and failures of pumping units of water supply and sanitation systems under operating conditions for subsequent analysis and development of recommendations for the design and operation of hydraulic systems in order to determine reliability characteristics based on the processing of the database at the enterprise by methods of mathematical statistics. According to the results of the scientific analysis carried out at the enterprise, the main causes forming the base of failures of pumping equipment were identified, priority causes of their occurrence were identified and an analysis was carried out on their operational, structural or design errors. Reliability parameters for four groups of pumping equipment used at the enterprise were evaluated, their analysis was carried out, and a schedule and regulations for periodic maintenance were drawn up.
