Product Details

First, Apoch HSNH three-screw pump: HSNH three-screw pump is a non-pulsating axial conveying lubricating medium with a certain lubricity of a quantitative volume of low-pressure rotor pump, suitable for the transport of fuel oil, lubricating oil, hydraulic oil, Oil such as mineral oil and lubricating liquid. The conveying medium shall not contain any abrasive particles or corrosive substances to the pump material. The spiral surface of the Wegelion HSNH series three-screw pump is made up of special type lines (cycloid). When the motor or motor drives the active screw, the vacuum is gradually formed in each sealing chamber in which the motor or motor drives the active screw. The liquid is inhaled at atmospheric pressure from the suction port. Along axial continuous, no pulsating transport to the outlet, no stirring, emulsification phenomenon. The ability to form the discharge pressure depends on the system load and the number of screw seal cavities, and also depends on the viscosity of the conveying medium and the driving speed. The active screw and follower screw of the HSNH triple screw pump adopt hydraulic balancing device. The liquid is transported in the pump cavity continuously, with uniform axial straight motion, no pulsation, low noise, stable operation, steady flow and pressure, stable work. The vibration is small. The components of Weiglion HSNH three-screw pump have good general interchangeability and can be disassembled and replaced at will. . Pump parts, simple structure, light weight, installation, use, easy maintenance, high efficiency, long life. The axial force of the follower of the three-screw pump is supported on the back cover or the active screw, and rotated by the hydraulic force, the follower is driven by the hydraulic force, and there is no mechanical contact between the active screw and the follower. There is oil film protection between screw and pump sleeve, so the screw surface only transmits hydraulic torque, does not bear force, also has no wear and mechanical friction. For all transmission parts, oil film protection and lubrication formed by the conveying medium. The radial rotation of the main rod of the triple screw pump can also be called by the balanced piston sleeve With the help of the clearance between the balance piston and the shaft sleeve, the high pressure cavity is separated from the seal cavity, and there is no leakage in the seal cavity. The oil return hole in the cavity is connected with the suction cavity of the pump, so it is not affected by the discharge pressure. Strong self-priming ability, energy saving and low consumption, no bottom valve and oil before each boot.
