Abstract:

The durable and reliable work of piston compressors and pumps used in the oil and gas industry has great importance for practice. Investigation of complex problems with respect to mechanical and thermodynamic phenomena in compressors and pumps gives the opportunity to solve the problems of increasing the durability of oil and gas exploitation and transportation. Increasing the efficiency and durability of the compressor-pump stations directly depends on the correct calculations and designing of the different elements and mechanical parameters of piston machines. The problem of determining the

Abstract:

Refering to figure 1 [Fig.1], an oscillating « flipper » piston (1) and its associated chamber (2) are maintained without reciprocal contact. No oil is required because there is no contact and so no friction. An oscillating shaft (22) maintains the oscillating « flipper »piston (1). Around shaft (22), a twisting seal (8) allows for absolute sealing. This characteristic is important for Stirling engines and oil-free compressors. Referring to figure 4 [Fig.4], the two oscillating « flipper » pistons on the left belong to a Stirling-Franchot engine, more particularly to a Stirling-Franchot engine

Abstract:

Piston dynamics plays a fundamental role in two critical processes related to fluid flow in reciprocating compressors. The first is the refrigerant leakage through the radial clearance, which may cause considerable loss in the pumping efficiency of the compressor. The second process is the viscous friction associated with the lubricant film in the radial clearance; certainly a significant factor in the compressor energy consumption. In the present contribution a numerical simulation of the piston movement inside the cylinder of a reciprocating compressor is performed. The compressor considered

Abstract:

Gas leakage is one of the main sources of inefficiencies in low-capacity reciprocating compressors, undermining the compressor performance by reducing the mass flow rate and increasing the energy consumption. In reciprocating compressors, leakage in the piston–cylinder clearance is driven by the piston motion and pressure difference between the compression chamber and the internal environment of the shell. This paper reports a parametric numerical analysis of leakage in the piston–cylinder clearance of a low-capacity reciprocating compressor. A simulation model based on the Reynolds equation i

The compression of the flue gas is one of the most critical processes of CO2 recycling in oxy-fuel combustion technology. With a 300 MW Oxy-fuel pulverized coal fired boiler taken as an example of study, the selection of compressors of its flue gas compressing system is analyzed by the thermodynamic calculation. In this paper, two centrifugal compressors with the same specification are in parallel running as Scheme 1 of selection, while an axial compressor and a piston compressor are in series operation as Scheme 2 of selection. It shows that the Scheme 2 has the advantage of the energy consum

Compared to conventional compressors, the linear compressor with a free piston can improve efficiency and save energy, but the displacement varies due to different load conditions, which seriously influences its performance. In this paper, based on the theoretical analysis, a self-sensing control system with a SPWM inverter and a PC software interface for a moving-magnet linear compressor is developed, and the displacement of the linear compressor which is under control is tested. The result shows the error of the control system is under 0.2mm, and the accuracy fulfils the requirements.

The current work investigates the relationship between the shape of an isolator of a concentric rotary piston compressor and the secondary peak pressure developed during each operating cycle. This peak pressure is developed when the piston passes through the isolator cavity, and it is negative for compressor efficiency. The aim of this paper is to identify the isolator cavity shape that minimizes this secondary peak to improve compressor efficiency. This study covers five different cavities that may be used in such compressors. Contrary to our expectations, the conclusion is that the best geom

Abstract:

Abstract Linear compressors have started to apply in refrigeration owing to their oil-free operation, capacity modulation by variable stroke and higher seasonal efficiency. Nevertheless, linear compressors are subject to a high seal leakage loss and piston offset (drift), particularly at high pressure ratios. Meanwhile, there is a reduction in the accuracy of resonant frequency prediction due to very nonlinear gas spring at high pressure ratios, leading to a reduction in the compressor efficiency. Two-stage operation is considered as a feasible solution to the aforementioned issues due to the

Abstract:

The failure probability of piston ring abrasion occupies the forefront in reciprocating compressor cylinder assembly. Due to the reciprocating friction between the piston ring and cylinder liner, the local vibration signal contains typical nonstationary characteristics with a seriously overlapped frequency band of impact signals, while the different featured signals are coupled with each other. Therefore, the identification of cylinder friction and abrasion fault modes has always been a hot and difficult problem in fault diagnosis of reciprocating compressors.

That is, the first part of the cycle in the stage, the gas is cooled, and the beginning of the compression process will occur at a lower temperature than the gas temperature at the standard suction po

Introduction. The article presents studies of the possibility of increasing gas pressure in one stage. Reciprocating compressors of road construction machines have been investigated, for which, as for any mobile stations, the issue of reducing the weight and size parameters of process equipment is acute. In this regard, the aim of the work was to expand the range of pressures obtained in single-stage piston machines. An alternative to the use of existing compressors with lubricated flow part can be compressors with seals based on fluoroplastic compounds that do not require liquid lubrication.

The current level of performance of piston compressors, characterized by the delivery coefficient, is at the level of 0,7. Advanced designs have higher rates, reaching values of 0,8...0,85. However, the negative effect of dead volume prevents the performance level of, for example, screw compressors from being achieved. Therefore, reducing the influence of dead volume on productivity can be considered the main task in improving modern piston machines. The presented work proposes a solution to eliminate the influence of the most significant component of the dead volume — linear space. As experim
