Nanjing Ai Branch Pump Co., Ltd. determined to create the world's best screw pump I. Overview HSN series three screw pump for conveying fuel oil, lubricating oil, hydraulic oil and other lubricants and lubricants. The medium to be transported must not contain any abrasive particles and material that corrodes the pump material. HSN Series Triple Screw Pumps are used as fuel pumps for conveying, boosting and fuel burners in fuel systems; as transmission and refueling pumps in oil delivery systems; as lubricating oil pumps in all industrial fields; for various Hydraulic pump in a hydraulic transmission. Applicable pressure range: 4.0Mpa, temperature ≤150 ℃, viscosity 3-760cst. Second, the structural features HSN series of three-screw pump screw formed by a special type of screw surface of the active screw rotation, the dynamic seal chamber will liquid from the inhalation Mouth inhalation and along the axial continuous, pulseless delivery to the discharge port. The main rod with hydraulic balance, axial force from the rod supported on the back cover, and driven by the hydraulic force rotation, so the screw-type surface only transmits hydraulic torque, is not force, nor wear, for all the transmission parts, By the transmission medium lubrication. The radial direction of the main rod is positioned by the balance piston, and the high pressure chamber and the seal chamber are separated by means of balancing the gap between the piston and the sleeve. A mechanical seal is arranged in the seal chamber. The oil return hole in the chamber communicates with the suction chamber of the pump , So from the discharge pressure. Available in horizontal (H), flange (F) and vertical (S) installations due to its versatile range of components. Depending on the media delivered, heating or cooling structures are also available. Third, the scope of application In the heating equipment used for fuel injection, fuel supply and pump. Used in the machinery industry as hydraulic, lubrication and remote motor pumps. In the chemical petrochemical and food industry used as loading, conveying and liquid pumps. In the ship for transport, booster, fuel injection and lubrication pumps and marine hydraulic pump.
