Non-ferrous metals industry ferocious gains

Recently, the non-ferrous metal has gained momentum. The three quarterly reports released by China Aluminum show that the company’s third-quarter loss was 118 million yuan, and it is expected to be profitable throughout the year.

China Aluminum is China's largest producer of alumina and primary aluminum, the world’s second largest alumina producer and the third largest primary aluminum producer. As of the first three quarters, the company’s total assets reached 139.9 billion yuan. From July to September this year, the company had a loss of 118 million yuan, while the net profit in the first half of the year was 530 million yuan.

China Aluminum's three quarterly report shows that the electrolytic aluminum industry has not taken a big rally. Since the beginning of this year, Lun Aluminum's price has shown a two-dip turbulent trend, with a maximum of US$2,500/ton and a minimum price of nearly US$1800/ton. According to the relevant personages of the China Nonferrous Metals Association, at present, among the non-ferrous metals, the aluminum supply is the most relaxed, tin is the tightest, and the balance is relatively balanced; however, the price of non-ferrous metals is more affected by the depreciation of the US dollar. Since the National Day, non-ferrous metals in the international market have risen sharply. This is the reason.

Rod Seals

1. Components of piston rod seal:

3. Use position of piston rod seal:

Guide sleeve, piston

4. Working principle of piston rod seal:

It is used at the contact part between the guide sleeve and the outer cylinder to seal the emulsion in the outer cylinder.

5. What effects will be caused by improper use or operation of piston rod seal:

1. Improper selection of cavity support material will wear the cavity and piston rod.

2. The size of the friction pair is inappropriate, causing wear.

3. Improper thread guide angle of cylinder barrel and piston end wear the sealing ring.

4. The seal ring is worn due to improper installation guide angle of the seal.

5. The surface of cavity and piston rod is rough, with scratches and worn seals.

6. The outer cylinder leaks and the jack does not maintain pressure.
