Press roll

The press roll is the main component of the press device. Both ordinary press and positive press use flat roll press. The structure of the flat roll press, the upper roll is a stone roll, and the lower roll is a rubber roll. Both rolls have flat and smooth roll surfaces. The bottom roll of the flat roll press is a rubber-coated cast iron roll.

Bow curved roll

The curved roller is a series of rotatable curved roller surfaces installed on the curved shaft to reach the roll that stretches the web, which can eliminate the wrinkles in the web traveling process and prevent the possible staggering during the material cutting process.

Guide roll

Paper machine guide rolls are divided into two types: felt rolls and screen guide rolls. The application parts include pressing, drying, crimping, rewinding and other parts. Felt ducts, wire guide rolls, paper guide rolls, chrome-plated rolls, etc. are all over the front and back of the paper machine. Guide rolls guide and drive the wire and felt in the wet end and drying section of the paper machine. The guide rollers in both areas use the same bearings. However, different lubrication and sealing are used depending on the application location. In the old paper machine, the wet end section is usually lubricated with grease, and the dry section is lubricated with oil. In modern paper machines, both sections are lubricated with oil circulation. Due to different working conditions, the wet end and dry section need to be lubricated with their own oil circulation.

Roots vacuum pump

Roots vacuum pump is characterized by: quick start, less power consumption, low operation and maintenance costs, pumping speed, high efficiency, to be pumped gas contained in a small amount of steam and dust is not sensitive, in the range of 100 ~ 1 pa pressure has a large pumping rate, can quickly exclude the sudden release of air. Widely used in petroleum, chemical, metallurgy, textile, papermaking and other industries.
