Marine Single-Screw Pump

Working Principle

Marine single screw pump by rotating the screw to achieve liquid delivery.
When the screw rotates, the liquid is sucked into the suction inlet of the screw, and with the rotation of the screw, the liquid is pushed into the chamber of the screw and is finally extruded from the pump body.
In the working process of the screw pump, because the gap between the screw and the pump body is very small, higher flow rate and lower pumping pressure can be achieved.


Application Field

Marine single screw pump has a wide range of applications in ships, mainly including fuel transport, lubricating oil transport, liquid cargo transport and so on.
Due to the particularity of the ship's operating environment, the stability and reliability of the pump are high, and the single screw pump has the characteristics of simple structure and smooth operation, so it is very suitable for the oil transport of the ship.


Maintenance

In order to ensure the normal operation of the Marine single screw pump, it is necessary to maintain it frequently.
First of all, keep the pump body and screw clean to prevent the inlet and outlet from being blocked by impurities affecting the normal operation of the pump.
Secondly, it is necessary to check the seal of the pump regularly to ensure that the sealing performance of the pump is good and to prevent the occurrence of oil leakage.
In addition, it is also necessary to replace the lubricating oil in time to ensure that the friction pair of the pump runs normally.

Marine single screw pump is a kind of pump equipment commonly used on ships. It has the characteristics of small size, simple structure and smooth operation, and is widely used in ship fuel transportation and lubricating oil transportation.
