1. AKP-HSNF three-screw pump: AKP-HSNF three-screw pump is a quantitative volumetric low-pressure rotor pump with certain lubricity medium, which is suitable for conveying fuel oil, lubricating oil and 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 AKP-HSNF series three-screw pump consists of a special type of line (cycloid), when the motor or motor drives the active screw, Each chamber in which it moves is gradually forming a vacuum, and the liquid is acting under atmospheric pressure. Suction from the suction and along the axial direction, 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 AKP-HSNF 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 AKP-HSNF three-screw pump have good general interchangeability and can be disassembled at will. Replace the corresponding parts. 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 runout of the main rod of the three-screw pump is flattened. The balance piston sleeve can also be called sliding bearing positioning, and 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, and the oil return hole in the chamber is connected with the suction cavity of the pump. Therefore, it is not affected by discharge pressure. Strong self-priming ability, energy saving and low consumption, no bottom valve and oil before each boot.


Second, AKP-HSNF three-screw pump performance characteristics: 1, high efficiency > low operating cost 2, axial balance rotor > bearing no axial force 3, only one shaft seal > easy to maintain, low cost 4, strong cavitation resistance > low noise, Minimized vibration 5, simple design > reasonable price 6, can be designed as unsealed magnetic or semi-submersible oil pump 7, the inlet and outlet can be exchanged by turning the pump body > universal 8, screw pump can be replaced screw, bushing, Pump core > screw pump parts full series universal interchange 9, flange support mounting three screw pump > coaxial automatic alignment, vibration Small, low noise, long life
