Marine low-pressure crude oil filter - Marine dual low-pressure crude oil filter - Marine dual oil filter
Executive standard: CB / t425-1994

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94
In the previous articles, we introduced the seawater filter in the ship pipeline. The filtering medium is fresh water or seawater. Of course, we also know that the medium circulating in the ship pipeline is treated water, and another is oil, which is divided into lubricating oil, diesel oil, heavy oil, etc.
When encountering this medium, we need to use a product - Marine low-pressure crude oil filter CB / t425-1994.

 

It can be seen from the physical picture of the above marine low-pressure crude oil filter that this low-pressure crude oil filter is composed of two cylinders, two filter elements and two cover plates.


This kind of composition is realized: when the equipment is not stopped, the switching function can be realized to facilitate cleaning. Therefore, this marine low-pressure crude oil filter is also called - switchable dual oil filter, switchable dual crude oil filter.
Through the above description, we have a certain understanding of the working principle of this dual crude oil filter. Now we will give you a brief introduction to one of the models.

AS80-0.25-0.16 CB/T425-1994
Low pressure crude oil filter - double low pressure crude oil filter - double oil filter - Double lubricating oil filter
As - indicates that the double oil filter is straight through type, and the flange standard is in accordance with gb2506-89 pn6.
80 - indicates that the nominal diameter of this double low-pressure crude oil filter is 80mm, which is applicable to the oil pipeline system with the outer diameter of steel pipe of 89.
0.25 / 0.16 - indicates that the precision of the internal filter barrel of this marine low-pressure crude oil filter is (square hole spacing 0.25 / steel wire diameter 0.16).
CB / t425-1994 - is the production design standard of this marine dual oil filter.

 

In order to accurately measure the data during maintenance and replacement, our company provides you with the basic structural dimension diagram of this as80 dual low-pressure crude oil filter:

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94
Note: the flange size of this marine low-pressure crude oil filter can be according to the customer's requirements. The following three types are commonly used, please refer to.

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94

 

After determining the overall dimensions, we should also consider the filtration accuracy of this low-pressure crude oil filter, because it can filter lubricating oil, fuel oil, heavy oil, etc., and its filtration accuracy is also different:

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94

Today, we will introduce a filter equipment in the marine fuel pipeline system - dual oil filter and dual low-pressure coarse oil filter.

 

According to the above differences in filtration accuracy, the common marking examples of this dual low-pressure crude oil filter are as follows:

First, we understand the installation environment of this dual low-pressure crude oil filter:

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94


As can be seen from the above figure, this dual coarse oil filter is a coarse filter installed at the inlet of the ship's fuel transfer pump, which coarse filters the fuel and then distributes it to other equipment for work.

 

When we replace this crude oil filter, we need to confirm the following points:


1. Accurately measure the section distance of the inlet and outlet flanges of the double low-pressure crude oil filter (as shown in the figure).

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94

 

2. Measure the flange size at the inlet and outlet, including the flange outer diameter, flange center distance and bolt hole size (as shown in the figure).

 

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94

 

3. Measure the installation base of the dual fuel filter, including the longitudinal installation center distance, horizontal installation center distance and bolt hole size (as shown in the figure).

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94

Based on the above measured values, we have drawn formal production drawings and confirmed with the customer:

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94

After we have determined the overall dimensions and connection dimensions of this dual crude oil filter, we also need to confirm an important data - the filtering accuracy of the filter barrel inside the oil filter:

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94
It can be seen from the title that cb/t425-1994, a national standard low-pressure crude oil filter, has many names. This is named according to the habits of customers in various regions.


Here we will give you a brief introduction to the dual low-pressure crude oil filter of Dn40 in this standard:
Model definition:

DUAL SWITCHABLE COARSE OIL FILTER MODEL: AS4080 0.4/0.22 CB / T425-94
Type A - straight through type, that is, the inlet and outlet flanges of this duplex low-pressure crude oil filter are at the same horizontal line and separated on both sides of the re oil filter body.
S- indicates that the flange standard of this duplex oil filter is in accordance with gb2501 pn6.
40 means that the working pressure of this low-pressure duplex oil filter is pn0.4 (generally omitted)
40 means the nominal diameter of this duplex crude oil filter is 40mm
Cb/t3594-1994 is an executive standard for domestic ships.

 

Of course, sometimes we find that the list description written by the customer is: oil filter as40-0.25/0.16 cb/t425. The extra (0.25-0.16) here represents the filtering accuracy of this marine duplex oil filter and duplex low-pressure crude oil filter. According to the standard, the common filtering precision is as follows:
