ABSTRACT

It is known that the service life of oilfield machines and mechanisms is to a certain extent determined by the operability of friction units, the operation of which, as a rule, occurs under severe conditions (heavy loads, abrasive aqueous medium, etc.). It is also known that the determining parameters in the units of machines and mechanisms (lubricated with water) with polymer elements are specific load, sliding speed and relative clearance. In the field, these factors affect the coefficient of friction together, therefore, the study of their influence [µ = f (p, ʋ, ψ)] on the coefficient of friction is possible only with the use of mathematical modeling. We have studied the nature of the joint influence of the main operating parameters on the performance of the ison thermoplastic elastomer plain bearings.

Keywords: Operation, polymer elements, field conditions, bearings, sliding speed.

ABSTRACT

The article examines the study of increasing the wear resistance of the cylinder-sleeve of a piston pump using the developed technology of plasma spraying. Wear-resistant and durable coatings of nickel, chromium, molybdenum and tungsten were obtained on the surface of the piston pump cylinder-sleeve. A graph of the dependence of the coating thickness depending on the surface hardness of the cylinder-sleeve is presented. According to the graph, depending on the hardness, you can determine the wear resistance of the coating surface of the cylinder-sleeve.

Keywords: piston pump, cylinder liners, plasma method, nickel, chromium, molybdenum, tungsten, wear resistance, coating thickness, hardness, graphical dependence

ABSTRACT

The generalized indicator of useful use, depending on the state of individual elements of oil-producing equipment, characterizes the ability of this equipment to perform its function during operation at optimal working time. The generalized indicator of the useful use of operational equipment can be described as the calculated sum of the indicator of the useful use of individual equipment elements. If, during operation, the oil-producing equipment retains its operability due to frequent replacement of its structural and non-structural elements, then such operational equipment is considered by users as outdated.

Operating equipment can be divided into 6 categories according to the indicators of suitability. The article analyzes the state of useful use of equipment and, as a result, the total utility of equipment is calculated in accordance with the indicators of useful use by category, and graphs of changes in the state of useful use are constructed. Based on the study of the graphs of the useful use of equipment, it was proposed to conduct an analysis in the following areas:

• Evaluation of the design and technological perfection of the equipment by users according to important new parameters.
• Determination of equipment compliance with wear standards during operation.

Keywords: structural element, wear theory, the usefulness of jam, categories, schedule of changes, reliability.

ABSTRACT

Over the past 20 years, 3D (three-dimensional) technology has become widespread as an advanced method for creating digital models of objects. This direction of science is used not only in the technical and space fields, but in the storage and protection of pharmaceuticals, museum exhibits and other cultural values ​​in the form of digital data.

Currently, the method based on laser scanning is of particular importance for obtaining accurate images among wide-sector methods for constructing digital models of objects. Although the limited application of the method is associated with financial and economic problems, the accuracy of data, the creation of artificial objects, characters using various editors and programs, their animation, as well as harmony with real objects and interiors have become key factors in the spread of this technology.

The article analyzes the process of obtaining a three-dimensional image of a model using two cameras using three-dimensional graphics editors.

Keywords: 3D technology, digital model, graphic representation, Monge method, modeling.
