Double filter-Double oil filter-Duplex oil filter
Low pressure crude oil filter
Definition of CB/T425-1994 double oil filter, duplex crude oil filter, duplex lubricating oil filter:
Double cylinder type oil filter, oil filter and double switch that consists of two single cylinder type oil filter in parallel or in series, two crude oil filter can be used alternately, replace the filter cylinder under the condition of no stop, can also double work at the same time.
Duplex crude oil filter, double fuel filter according to action / medium can be divided into:
CB/T425-1994 double heavy oil filter, double diesel filter, double oil filter
CB/T425-1994 fuel delivery pump, duplex oil filter, hydraulic oil inlet pump, duplex crude oil filter
CB/T425-1994 light diesel oil transfer pump, dual oil filter, light diesel oil transfer pump, double crude oil filter
CB/T425-1994 oil purifier outlet double oil filter, fuel oil distributor outlet double crude oil filter
Crude oil filter - duplex crude oil filter - Dual Low Pressure crude oil filter - duplex can switch fuel filter components:
This double coarse oil filter is composed of a filter cylinder body, cover, valve, filter, switch handle:
Its working principle is that:
The suspension is pumped into each airtight filter chamber of the filter machine, and under the action of the working pressure, the liquid is discharged through the liquid outlet, and the filter residue is left in the box to form a filter cake, so as to achieve the solid-liquid separation, and the impurity particles are blocked by the filter bag.
Our company (Yangzhou flying ship accessories factory) produces the marine double connection crude oil filter, the main model has:
A, AS type through type double oil filter, double connected crude oil filter, double connected fuel oil strainer
A, AS type cast iron double oil filter, cast iron double connected crude oil filter, cast iron double connected fuel oil strainer
Duplex oil filter - duplex crude oil filter - switchable dual oil filters
