“…Now take commonly used No. 32, 46, 68, 100, 150 anti-wear hydraulic oil and water as examples for comparison, and list their SVPs at 20℃ and 60℃ in Table Ⅲ [53], [54]. Apparently, the SVP of water is much higher than that of hydraulic oil.…”

Hydraulic systems have been frequently used in deep-sea equipment because of their renowned long service life, stable and reliable performance. However, impurities contained in hydraulic oil, such as solid particles, gas and water, would jeopardize work efficiency of deep-sea hydraulic systems, and in some extreme cases even cause failure of the whole system, resulting in breakdown of crucial deep-sea equipment. Therefore, this paper aims to present a device, multifunctional oil-injection equipment (MOIE), expected to be able to purify hydraulic oil in deep-sea hydraulic systems. Its major functions are to absorb oil, remove impurities and fill oil, among which the removal of water and gas, i.e. dewatering and degassing, is of significance. Theoretical analysis shows that the paper oil filter is able to remove the solid particles in hydraulic oil, and degassing and dewatering of hydraulic oil could be achieved through vacuum filtration and vacuum heating in high-temperature and low-pressure environment. The prototype of the MOIE is designed and manufactured. The results from laboratory experiments indicate that this equipment can effectively remove solid particles, gas and water from hydraulic oil. This study ensures the stability, safety and reliability of the deep-sea hydraulic system by improving the quality of hydraulic oil.

“…The effusion method, which measures the force or the mass loss due to the ejection of vapor from a sample holder, uses only a small sample; however, it requires a mean free path of at least a few millimeters, which makes it unsuitable above 10 Pa. Of the remaining methods, the static method used here is the most accurate, and it can be applied at any pressure for which one has a suitable sensor, from less than 1 Pa to more than 10 MPa. Examples of static method apparatuses can be found in refs − .…”

This article describes an apparatus and method for measuring vapor pressures in the range from 1 Pa to 105 Pa. Its three distinctive elements are : (1) the static pressure measurements were made with only a small temperature difference between the vapor and the condensed phase, (2) the sample was degassed in situ, and (3) the temperature range extended up to 200 °C. The apparatus was designed to measure metal-organic precursors, which often are toxic, pyrophoric, or unstable. Vapor pressures are presented for naphthalene, ferrocene, diethyl phthalate, and TEMAH (tetrakisethylmethylaminohafnium). Also presented are data for the temperature-dependent decomposition rate of TEMAH.
