Large flow delivery pump HSN2900-40N three-screw pump

1. Overview
The series of three-screw pumps are suitable for transporting fuel oil, lubricating oil, hydraulic oil and other oils and lubricating liquids. The transported medium must not contain any abrasive particles and substances that are corrosive to the pump materials.
The series of three-screw pumps are used as fuel pumps for pressurization and fuel burners in fuel systems. They are used as transmission and refueling pumps in oil delivery systems. They can be used as lubricating oil pumps in all industrial fields and are used in various hydraulic systems. Hydraulic pump in transmission. Applicable pressure range:, temperature °C viscosity
Two structural features
When the active screw of the helical surface composed of special lines rotates, the dynamic sealing chamber of the series three-screw pump will suck the liquid in from the suction port and Continuously pulsation-free delivery to the discharge port along the axial direction. The main rod is hydraulically balanced, and the axial force of the slave rod is supported on the back cover and driven to rotate by hydraulic pressure. Therefore, the screw profile only transmits hydraulic torque and is not subject to force or wear. For all transmission parts, All are lubricated by the transported medium. 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 the gap between the balance piston and the shaft sleeve. A mechanical seal is installed in the seal chamber, and the oil return hole in the chamber is connected with the suction chamber of the pump. , so it is not affected by the discharge pressure. Due to the universal combination of components, the series has a variety of structures and can be used for horizontal, flange and vertical installation.
Heating or cooling structures can also be provided according to the needs of the transported medium.
Three application scopes
Used as fuel injection, fuel supply and transfer pump in heating equipment.
Used in the machinery industry for hydraulics, lubrication and remote control motor pumps.
Used as loading, conveying and liquid supply pumps in the chemical, petrochemical and food industries.
Used on ships to deliver pressurized fuel injection and lubricating oil pumps as well as marine hydraulic device pumps.
