Tasuno Gear Pumps for Fuel Dispensers

1. 1. ZYB-90 Gear Pump is designed and manufactured with American advanced technologies, and material of the main body is alloy aluminum founded low pressure. Air separator, bypass valve, check valve and filter are built inside it. It is designed for gasoline, diesel, kerosene or compound of them. It has the features of pretty design, high vacuum, long suction head, stable performance, low noise and long service life and so on.
   2. Working Principle: After starting motor, high-pressure vacuum zone is produced in the pump, petroleum in pipe is sucked into pump by the high pressure vacuum, then petroleum passes through air separator and filter, in which gas and other airs are separated from petroleum, then the pure petroleum is put into flow meter with the constantly running gear.

Optical brightener

The role of the brightener is to convert the invisible ultraviolet radiation absorbed by the product into purple-blue fluorescent radiation, which complements the original yellow radiation to become white light, and improves the whiteness of the product under sunlight. Brighteners have been widely used in textiles, papermaking, washing powder, soap, rubber, plastics, pigments and paints.

Generally, brighteners are divided into two categories, one is water-soluble brighteners, and the other is water-insoluble brighteners. The former can be used as a brightener for paper, paint, washing powder and cotton fabrics. The latter can be used for whitening of chemical fibers and plastics.

It is often divided into:
Fluorescent brightener for detergents; Fluorescent brighteners for textiles; Fluorescent brighteners for papermaking; Fluorescent brighteners for plastics and synthetic materials; Fluorescent brighteners for other purposes.

This product is especially used for the molding and processing of various plastics and plastic products under high temperature. Because of its good heat resistance, light resistance and chlorine resistance, it is a brightener for polyester fibers. Polyester, cotton and other fiber blended fabrics The whitening effect is also particularly ideal, and can be used for the whitening of polyester stock solution.
