“…Under the action of working pressure, the V-shaped rubber sealing rings have deviation effect [7], [8]. That is, the lip of the V-shaped sealing rings will depart from the plunger surface, so abrasive will enter the plunger sealing friction pair, especially in the suction stroke of fracturing pump.…”

Abstrak Kegagalan penyegelan timbal-balik di dalam keretakan pompa OPI-1800AWS telah dianalisis kegagalannya dengan teknologi pemindaian mikroskop elektron (SEMT). IntroductionAt present, the proportion of increasing oil and gas production by fracturing or acidification technology is getting larger. A successful fracturing may increase the production of oil and gas wells several times, even more than a dozen or dozens, the benefit is extremely considerable. According to the working principle of fracturing and acidification, large displacement and high-pressure injection are necessary for this technology, and fracturing pump is the core equipment to complete the work. In the long-term practice and research, fracturing and acidification technology is getting better and better, in contrast, fracturing and acidizing equipment is not compatible. This seriously affects the normal implementation of the fracturing and acidizing technology [1], [2]. The working conditions of plunger, V-shaped seal, valve disk and valve seat are seriously bad. These wearing parts are the weakest link of the fracturing pump. From the current using of plunger and seals used in oil fields in China, their lifetime is very low, and for annual consumption is great. The investigation indicated, in Sichuan area, during acidizing operations, the lifetime of plunger is more than 100 hours, the lifetime of sealing ring is 30-40 hours, sometimes 10-20 hours. With the frequent fracturing and acidizing operation, the lifetime of plunger and seal will become increasingly prominent. So, the site urgently requires the systematic study of the plunger seal friction pair in fracturing pump, in order to improve their lifetime and ensure the smooth construction. This paper intends to carry out systematic research on the plunger seal friction pair of OPI-1800AWS fracturing pump. All these can provide a basis for design improvement and experimental research of reciprocating sealing in high-pressure fracturing pump.

“…For the first category, there are several related studies that have been done. Among them is by setting the temperature at the farm [1], or by choosing the best location to be broiler farm [2], and simulating mathematically the environment of broiler farms [3]. For the second category, among others, research related to broiler health level affected by viral infection, causing large-scale harvest failure and reduced stock of broiler meat and influencing the economy of a country [4].…”

“…(Linker et al, 2011;Daskalov et al, 2006;Xin et al, 2001) To maintain the air temperature and humidity inside the poultry house at the desirable level in a hot, humid climate in a country, such as Thailand or Indonesia, ventilation fans, evaporative cooling systems, and electronic controllers are essential components. Moreover, many recently developed devices and technologies have been applied to the poultry house environment control related works (Tiwari et al, 2006;Alimuddin et al, 2012). But studying the effects of implementation of a new device or a new control method in real poultry houses can be difficult to achieve, not only because of the potential for errors and potential side effects on the production process, but also the time allocation required to study and collect the data throughout the breeding cycle.…”

“…Among some previous works developing the model on computational fluid dynamics (CFD) to study the building's climate behavior, most of the case studies are about the minimum ventilation schemes for cold weather regions, and others are naturally ventilated cases (Tiwari G.N, et al,2006;Alimuddin, et al, 2012;Rojano et al, 2015). Many studies focus on temperate or air distribution of the poultry house, regardless of the humidity, which is one of the factors that indicates the heat stress index for chickens (Alimuddin et al, 2012;Rojano et al, 2015;Nääs et al, 2010;Calvet et al,2010;Agbi et al, 2012).…”

The temperature and humidity inside poultry houses are highly coupled through nonlinear psychrometric processes, and the limitation of actuators makes this type of system difficult to control. To understand the dynamics of such systems and further to design a suitable controller, in this study, the mathematical model for a closed poultry house was derived from the governing equations of the various components related to the poultry house, including the energy and mass balance and the psychrometric correlations of the moist air. The model was simulated and the simulation result was compared to the data collected experimentally for model verification and control gains estimation. Under the assumptions of 70 percent Active Mixing Volume (AMV) with the constant maximum ventilation rate in the case study, the temperature and the relative humidity simulated results were in the good agreement with the real physical plant data. At the front, the middle and the rear part of the poultry house, the rootmean-square error (RMSE) obtained for internal temperatures are 1.
