Product Description

                                      China Bernoulli  Industrial Water Filter Manufacturers


1.Working principle

Filtering state: Liquid from the Backflush Filter for High Viscosity Liquid inlet injection, from up to down flow, through the filter element surface to flow outlet; When the filter element surface collect to a certain impurities, fixed time or set pressure tp started cleaning procedures.
Cleaning state: cylinder drive wash plate to straight action, this part of the impurities with the descending liquid through washing dish to fall into the collection chamber, to repeat washing several times to clean the filter element.

The most important part of the filters, that provides quite simple and reliable cleaning process, is a disk which is installed on pneumatic cylinder. When a disk, placed on pneumatic cylinder's end, passes between water and filter basket, filter basket is cleaned with this movement of the disk. Flow speed of the water increases on the points around the disk and static pressure decreases pursuant to Bernoulli principle
Low static pressure creates vacuum effect on edge points of the disk and contaminants are discharged from the drainage line by being cleaned from the filter basket.

2.Technical Features and Benefits

1,Linear reciprocating stripped, directly stripped the impurities off the surface of the filter element.structure simple, easy open to clean and maintain
2,Online connection filtering, automatic dynamic line, end of the heavy filter element replacement and cleaning.

3,No need produce one-off abandoned filtration consumables, saving the cost of consumables and environmental treatment cost minimal filter pressure drop, flow stability, saving energy pipeline, which will help the process of continuous and stable.
4,Closed filter, to prevent leakage of hazardous materials which is conducive to safe production.
5,High concentration of emission waste impurity and recyclable , to avoid high-value materials losses
6,Variety of module combination and powerful automation modes, to meet the requirements of various filtration applications
7,Selection of the world-renowned high-quality components, high reliability, minimal maintenance,
low cost fixed line

700	1.1	165

4.Main Specifications

For the liquid: water and viscous liquids (<30000cps), impurity <1000ppm
Filtration (microns):100-3000
Standard design pressure rating: 1.0Mpa, higher pressures can be customized
Cleaning pressure: 0.05Mpa Drive: Cylinder

5.Advantages

1,Easy maintenance and high operation reliability thanks to a simple and smart cleaning
2,system with a part, moving a little bit.
3,Stable and low pressure loss both in clean and dirty conditions.
4,Need for low washing pressure to 0,3, bar.
5,Easy installation: Backflush filter for high viscosity liquid can be carried by pipe installation, on which they are installed. Filter can be installed horizontally and vertically.
6,PVC or glass fibre reinforces polyester body material provides high corrosion resistance particularly in sea water applications. Stainless steel bodied filters can be used in fresh water applications

6.Applications

1,The domestic water supply, water supply and pre-filtering for industrial water supply;
2,steel, petroleum, chemical, paper, automotive, food, metallurgy and other industries beginning circulating water filtration;
3,Fist stage of circulating cooling water filtration;
4,The water reuse, waste water treatment filter;
5,Central air conditioning, boiler return early filter;
6,Municipal, green spraying, irrigation, agricultural irrigation, drip irrigation water filter early.

7.Mechanical Installation

Cover:Cover and body can be installed in an opposite way of the shipment due to the requirement on transfer opening. Initially; it is recommended to install the body without cover. Before being installed , check if loose matters or connection lines are available in the filter.
Gaskets: Gaskets shall be carefully tightened for PVC and GRP flanges. GRP flanges generally require pre-tightening
Position:Filter can be installed in any way as seen on Figure 1-b. Nevertheless; filter body, connections and differential pressure switch shall be horizontal to prevent air accumulation and contamination in air tube. Filter shall be installed in a way it would possess positive pressure downwards to the pump,
as shown on Figure 1-c.
Supports: Filter is can be connected directly or in a way it is supported by pipe connections or pipes.
Control Board: Position of the control board shall be in sight of the filter
