Marine Vertical Three Screw Pump

Marine Vertical Three Screw Pump

Screw Pump Introduction

The three-screw pump is formed by the pump body and the screw. When the driving screw rotates, it drives the driven screw that engages with it to rotate together. The volume of the screw meshing space at one end of the suction chamber gradually increases and the pressure decreases. Generally, a mechanical seal is used, and the pump is driven by a motor through a claw coupling. Viewed from the extended end of the main shaft to the pump, it rotates clockwise. It is used in all fields widely to feed kinds of medium, running at a constant pressure continuously, without and damage when feeding medium, and change the gauging through adjusting rotation speed.

Screw-type Pump Advantages

• The axial low-pressure balance is adopted in the form of double sleeve, the main and driven screws are in the tension state during operation, so the screw is not easy to be deformed, and the driven screw is reduced in friction and better rotating work; the product is high-grade and the appearance is exquisite. Precision parts: 1 Most parts are made of aluminum alloy, precision die-casting; 2 self-corrosion, paint-free, beautiful, and can upgrade the grade of the unit; 3 innovative structural design, simplifying the overall design while meeting performance requirements The structure is simple and compact; the body size is small, the weight is light, the volume is 1/2 of the conventional product, and the weight is 1/3 of the conventional product.
• The product has long service life, reliable operation, wear-resistant and anti-seizure on the working surface: the pump body
• adopts double-layer composite design of copper in the outer aluminum, and the copper alloy is used as the pump body and the screw joint surface material to improve wear resistance and seizure resistance, and improve The product's performance, extended service life and expanded product range; no oil spill, meet environmental requirements: 1 choose brand mechanical seal; 2 two-way seal protection design; 3 internal flow channel design, to ensure that the seal cavity is not short of oil, No boost, no warming;
• High performance, substitute import, win import: 1 material combination is better; 2 reasonable inlet flow rate design to ensure stable fluid flow during high speed operation; 3 combination of import and export multi-direction, adapt to design and site needs; 4 simple and perfect structure The service system fully guarantees the user's good use on site; due to the simplified design of the structure, it is very convenient to install, disassemble and maintain; the supply of various forms can be supplied by the whole machine, and the pump head can be supplied for more flexible satisfaction.

Single Screw Pump Operation Principle
A screw pump is a type of positive displacement pump that uses one or more screws to move fluids through a system. The screw(s) rotate in a cylindrical chamber, and as they turn, they trap fluid and move it from the inlet to the outlet of the pump. Screw Pumps are known for their ability to handle a wide range of fluids, including high viscosity liquids, slurries, and liquids with solid particles. They can also operate at high pressures and with low pulsation, making them a popular choice for many industrial applications.

Progressing Cavity Pump Application

Products can transport all kinds of media with lubricity and no solid particles, mainly conveying lubricant (oil) media, such as lubricating oil, mechanical oil, hydraulic oil, gear oil, turbine oil, etc. While meeting the requirements of the original three-screw pump, it can also meet the conditions of high-rotation and low-viscosity conditions, and is suitable for machinery, petrochemical, metallurgy, steel, shipbuilding and other industries.
