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.

Compression injection molding: it is an advanced form of traditional injection molding.Advantages: it can increase the flow length ratio of injection molded parts; Adopt less clamping force and injection pressure; Reduce the internal stress of materials; And improve processing productivity.Injection compression molding is applicable to products made of various thermoplastic engineering plastics, such as large-size curved parts, thin-walled parts, miniaturized parts, optical lenses, and parts with good impact resistance requirements.

Low pressure injection molding:Low pressure injection molding process is a packaging process that uses very

low injection pressure to inject hot-melt materials into the mold and solidify rapidly. With the excellent sealing performance and excellent physical and chemical properties of hot-melt materials, it can achieve the effects of insulation, temperature resistance, impact resistance, vibration damping, moisture-proof, waterproof, dustproof and chemical corrosion resistance, and play a good role in protecting electronic components.
