Answer: Industrial sulfuric acid is a colorless to slightly yellow or reddish-brown liquid. Relative density 1.84 g/cm3 (20°C) ； Melting point: 10.35℃ ； Boiling point 338°C. It has a strong water absorption capacity, can be mixed with water in various proportions, and releases a large amount of heat. It is highly corrosive. Rinse the burned area immediately with plenty of water, followed by rinsing it with a saturated sodium bicarbonate solution. In cases of severe burns, seek immediate medical attention at a hospital. 2. What is cavitation in centrifugal pumps? Answer: Cavitation: When the low pressure in the center area of the impeller is equal to or less than the saturated vapor pressure of the liquid at the conveying temperature, the liquid vaporizes there and bubbles are formed; these bubbles move with the liquid from the low-pressure area to the high-pressure area ； Bubbles condense or burst in high-pressure areas, and the surrounding liquid rushes into the space formerly occupied by those bubbles at extremely high speeds, generating shock pressure. The high frequency of such shocks can cause damage to areas such as the back of the impeller and the pump casing, as well as increase the vibration and noise levels of the pump. This phenomenon is known as cavitation. 3. Concept of crystallization operation: Answer: Crystallization is the process by which solid substances precipitate out in crystal form from vapor, solution, or melt; it is the fundamental unit operation for obtaining highly pure solid substances. 4.

What are the self-pressurization value, interlock shutdown value, and shutdown pressure value for the lubricating oil auxiliary pump of the new hydrogen compressor? Answer: The new hydrogen compressor’s lubricating oil main line pressure triggers an automatic shutdown at 0.20 MPa; the auxiliary oil pump starts up at 0.28 MPa, operation is permitted at 0.35 MPa, and the auxiliary oil pump stops at 0.60 MPa. 6. Conditions for starting the new hydrogen compressor: Answer: A. The pressure in the lubricating oil main line of the new hydrogen compressor is greater than 0.35 MPa; B. The temperature of the lubricating oil main line is greater than 27°C; C. The crankshaft rotation mechanism is disengaged. 7.

Answer: (1) The main oil pump is damaged and the auxiliary oil pump fails to start supplying oil in a timely manner ； ⑵Leakage or rupture of the oil supply system pipes and connection flanges, blockage of the oil pipes ； ⑶An excessively low oil level in the tank results in the oil pump drawing in a small amount of oil or failing to draw any oil at all. 8. Why is it necessary to stop the compressor when the lubricating oil pressure drops suddenly by a large amount? Answer: When the lubricating oil pressure drops sharply, the supply of oil to various friction points becomes insufficient; in severe cases, the oil supply is completely interrupted. This leads to increased friction between the components, a rapid rise in temperature, and can result in bearing burnout or shaft seizure. 9.
