Abstract

The invention discloses a high temperature heat pump lubricating oil and working medium compatibility test device and test method. The device includes an oil storage tank for placing lubricating oil to be tested, a pressure-bearing water tank for adding water to the oil storage tank and a gas-entrapping pressurization system for conveying working medium gas to the oil storage tank and maintainingthe pressure in the oil storage tank constant. A heating component is also arranged in the oil storage tank. The device realizes quantitative water addition, and can calculate to obtain the dissolvedgas working medium. At the same time, a liquid of a hydraulic oil tank is used for sealing, and the pressure in the oil storage tank is kept constant during heating, so that an ideal and constant hightemperature and high pressure testing environment for testing compatibility is constructed.

Description

technical field [0001] The invention relates to a high temperature heat pump lubricating oil and working medium compatibility testing device and a testing method based on the device. Background technique [0002] At present, lubricating oil is mainly used in refrigeration and ordinary heat pump systems, and less attention has been paid to the applicability of lubricating oil in high-temperature heat pump systems. [0003] In high-temperature heat pump systems, lubricating oil has to face problems such as performance degradation of lubricating oil under high temperature and high pressure, chemical reaction with equipment or system impurities, etc., resulting in unstable and reliable operation of high-temperature heat pump systems. [0004] In order to evaluate the performance of lubricating oil in high-temperature heat pumps, it is necessary to test the influence of water content and gas content on the compatibility of lubricating oil and working gas under constant high tempe...
