High Flexibility

High pressure hose (HPH) is a flexible pipeline for the transportation of special hydraulic and motor fluids based on mineral oil, liquid fuel, grease or water emulsion under pressure, to transfer the working force. Structurally, the sleeve is two or more rubber tubes placed one into the other, reinforced with metal braids or coils, equipped with connecting fittings [1]. HPH is characterized by a sufficiently high flexibility in combination with the ability to withstand significant pressure.In cases of premature failure of high-pressure hoses during cyclic or impulse tests, the cause of the nonconformity must be determined. The article describes the main stages of the study of defective high-pressure hoses in determining the cause of their failure and provides examples of studies using visual, metallographic, electron microscopic methods of analysis in the metallographic laboratory of OJSC «BSW – Management Company of Holding «BMC».

Lubricant Rheology

The modified WLF equation developed in Part 1 was applied to the variation in viscosity, μ(T,P), for two series of binary blended lubricants containing a common synthetic diester (di(2ethylhexyl)sebacate) in a polyphenyl ether (5P4E) and in a naphthenic mineral oil (N1). Dilatometric observations and the viscosity analysis indicate that the relations needed to predict the pressure functions in the modified WLF equation for the binary mixture can be obtained from those of respective components. These relations allow us to estimate μ(T,P) of a binary blended lubricant without measurements of the high pressure viscosity of the blend. For practical applications, the modified WLF equation may also be useful for predicting μ(T,P) of blended lubricant products.

A high-pressure chamber is used to study lubricant compressibility when refrigeration oil is diluted by refrigerant. The tested lubricant in this work is a POE (polyol ester) oil, POE diluted with nonchlorinated (HFC) refrigerant R-134a, a naphthenic mineral oil, and the mineral oil diluted with the chlorinated (HCFC) refrigerant R-22. The high-pressure chamber experiments show that by adding 20 wt% of R-134a to the polyol ester oil, the stiffness of the lubricant increases by approximately 38 wt% at 1 GPa and is much higher than for R-22 and mineral oil.

Invasive Management

Equipment used in the mass vaccination of farm stock is a source of high pressure injection injury. We present four cases due to chicken vaccine, and one due to pig vaccine. Unlike injuries caused by paint or oil guns the vaccination delivers a fixed volume. Although the vaccine is in a mineral oil carrier it appears to elicit little inflammatory reaction in a small dose. The outcome is related to the volume injected. In chicken vaccine the dose is small enough to allow conservative or minimally invasive management. The large volume in pig vaccine requires treatment as for conventional high pressure injection injuries.

Energy Equations

A study is presented of high-pressure squeeze films between flat disks which approach each other at a constant velocity. The dependence of the viscosity of the oil on the fluid temperature and pressure is included in the momentum and energy equations. A single dimensionless parameter which involves only fluid properties determines whether the load capacity will be greater or less than that predicted by an isoviscous analysis. Excellent agreement is found between the results of a numerical analysis and the results of experiments in which mineral oil is confined between steel boundaries.

The ultrastructure of cells suspended in physiological fluids or cell culture media can only be studied if the living processes are stopped while the cells remain in suspension. Attachment of living cells to carrier surfaces to facilitate further processing for electron microscopy produces a rapid reorganization of cell structure eradicating most traces of the structures present when the cells were in suspension. The structure of cells in suspension can be immobilized by either chemical fixation or, much faster, by rapid freezing (cryo-immobilization). The fixation speed is particularly important in studies of cell surface reorganization over time. High pressure freezing provides conditions where specimens up to 500μm thick can be frozen in milliseconds without ice crystal damage. This volume is sufficient for cells to remain in suspension until frozen. However, special procedures are needed to assure that the unattached cells are not lost during subsequent processing for LVSEM or HVEM using freeze-substitution or freeze drying. We recently developed such a procedure.
