MARINE SUCTION PORT
In the previous article, we introduced several types of filters in the marine pipeline filtration system. I believe you have a preliminary understanding of them.
Today, we will introduce another product of marine piping accessories - Marine suction port.
First, let's understand the working principle of the marine suction port:
The marine suction port is a common accessory in ship piping engineering. In different tanks, the functions of the marine suction port are different: in the oil tank, the marine suction port can provide fuel for the main engine; In the ballast tank, the ship can adjust the state of the ship and the cargo load through the marine suction port.
According to the working principle of the marine suction port, we can see that it is a component of the bilge water pipe system.
According to the location and installation of the suction port, it can be divided into oil tank suction port and water tank suction port. The external structure of the two is also greatly different (as shown in the following figure):
Next, we will give you a brief introduction to the suction port of type a water tank:
