The inspection and maintenance methods for cracks include:1. Permeation kerosene method: The inspection process involves first wiping the machine body and cylinder head with a cotton yarn soaked in kerosene, and then using dry cotton yarn to wipe areas where cracks may appear with kerosene. Immediat

1. Keep the lubricating oil in the oil pool within the height range specified by the oil dipstick. The characteristics of the lubricating oil in the oil pool at the bottom of the aircraft body should meet the requirements;2. Check if the oil level in the injector is below the marking value. Turn the

Laser cutting is a commonly used material processing technique, in which nitrogen is used as an auxiliary gas in some cases. The following are several reasons why laser cutting requires nitrogen gas:

Reasons and treatment measures for crankshaft fracture of piston compressor

Reasons for oil consumption in piston compressors

In the helium recovery and purification system, the compressor is one of the very important equipment, and its selection should be reasonably designed and adjusted based on the properties and requirements of helium to ensure the quality and safety of helium. Here are some suggestions for choosing a compressor

Carbon dioxide is an oxide of carbon, with the chemical formula CO2. It is a colorless, odorless or colorless gas, and aqueous solutions have a slight sour taste at room temperature and pressure. It is very common. High purity carbon dioxide is mainly used in the electronics industry and as a regulator for polyethylene polymerization.

Helium recovery and purification is a field with important application prospects. Helium is an important rare gas with characteristics such as inertness and good airtightness. It is widely used in various industries, such as medical, scientific research, aerospace, and so on. However, the supply of helium is limited and global resources are gradually decreasing, making the recovery and purification of helium particularly important.

Recovery and purification of CO2 Carbon dioxide recovery devices are currently widely used in the beverage and food industries, and are also the most economical method for producing high-purity food grade carbon dioxide, provided that there is sufficient quantity and quality of crude carbon dioxide gas. The carbon dioxide recovery device is mainly used for the washing, purification, drying, liquefaction, and storage of CO2 gas received from the fermentation process, calcium chloride reaction process, and dry ice production process in breweries and distilleries. The carbon dioxide recovery device is automatic and requires the lowest operating cost.
