 ABSTRACT

 The main purpose of rotary drilling is to perform well drilling and completion (preparation for production) by spending the least amount of money. Drilling rigs are divided into two classes, onshore and offshore rigs. Their main distinguishing features are mobility, adaptability for different operations, maximum drilling depth. The rig components are essentially the same for onshore and offshore rigs. The only major difference is that offshore installations have a pipe called a riser that connects the gas field to the wellhead on the seabed.

Drilling rotors work using a battery or hybrid engine. They are driven along with the drilling bit, which is used to replace the harmful gases in the initial drilling process. With technological advancements over the past century, drilling rotors have become more efficient and effective.

One of the first types of drilling rotors is the drill bit, which is used to bore down to the base of the indicated site. These rotors are traditionally used for opening up the borehole, lowering chains, and determining the indicated source. Drill bits are mainly used in mining rocks and mountains.

The second type of drilling rotors is the polycrystalline diamond compact (PDC) rotors, which are specifically used in the gas and oil industry. PDC rotors feature synthetic diamond teeth, and they work faster and more efficiently. These rotors are considered a crucial component of several drilling machines in gas extraction sites.
Finally, high-speed rotors are one of the last rotor types used in drilling activities. These rotors are globally used for gas and oil extraction. High-speed rotors are capable of generating enough force and torque to penetrate through the earth's crust and extract the desired material.

Key words: Polycrystalline Diamond Compact (PDC), Heavy Weight Drill Pipe(HWDP), Finite Element Analysis (FEA), Hot İsostatic Pressing (HIP).

 ABSTRACT

 Increasing energy efficiency is the most important energy source today. Therefore, the main success criterion of product development studies is seen as efficiency. Compressors; It is widely used in many different sectors, especially petro-chemical, electronics, automotive, food, machinery, glass, machining, textile, construction. In our daily life, compressors are among the indispensable main components in refrigerators we use at home and in transportation (bus, train, truck). To put it in a nutshell, while people need air to live, the operation of industry depends on compressed air. Compressed air requirement is provided by compressors without alternatives. According to research, approximately 10% of industrial energy consumption in Europe and Australia is used for compressed air production. However, the energy consumed for the production of compressed air in some sectors in the USA reaches up to 30% of the total energy consumed. These studies have shown that the compressors used for the production of compressed air in the industry are the main machines that cause energy consumption. Therefore, energy efficiency in compressors is one of the main criteria for the industry.

When the screw compressor development studies are examined in the literature, the main working area is to increase the efficiency of the compressor and reduce the operating costs. This study covers the parametric optimization of the components that affect the performance of an oil type screw compressor with a one-dimensional thermodynamic model, using RSO (Response Surface Optimization Technique) and Taguchi optimization techniques, which are widely preferred in the literature. Stosic et al. investigated the performance of the rotor profile tooth depth on the compressor in their study. The outer diameter of the female rotor and the distance between the rotors, which affect the rotor tooth depth, were also investigated parametrically.

 ABSTRACT

 Reciprocating compressors are machines that are used to compress gas or air by means of reciprocating motion. They are widely used in various industries, including oil and gas, petrochemicals, and manufacturing, for applications such as gas transportation, pneumatic power tools, and refrigeration. The basic components of reciprocating compressors include the molding elements, crankshaft, connecting rod, cylinder, intake valve, discharge valve, and lubrication system. There are two primary types of molding elements used in reciprocating compressors: piston and diaphragm. Piston molding elements are the most common and offer high efficiency, low maintenance, and high reliability. Diaphragm molding elements are an alternative to piston molding elements and provide oil-free compression, high purity, low noise, and low vibration. The choice of molding element depends on the application requirements. Reciprocating compressors are widely used due to their efficiency, reliability, and versatility in a range of applications.

The molding elements of reciprocating compressors play a critical role in the efficient operation of these machines. The molding elements, such as pistons, rings, cylinders, valves, and connecting rods, are subject to significant wear and tear during the compression process, which can result in reduced efficiency, increased energy consumption, and even complete equipment failure. To address these challenges, various design improvements and material selection strategies have been developed to improve the durability, reliability, and efficiency of molding elements in reciprocating compressors. This article provides an overview of the key molding elements in reciprocating compressors and examines various methods and techniques for improving their performance and efficiency, including advanced material selection, innovative design solutions, and effective maintenance practices.

Keywords: molding elements, reciprocating compressors, pistons, rings, cylinders, valves, connecting rods, compression process, efficiency, energy consumption, equipment failure, design improvements, material selection, durability, reliability, advanced material selection, innovative design solutions, maintenance practices, performance, efficiency.
