ZJDP IV guided-flow self-cleaning filters |
1, function and use
JDP type IV diversion self-cleaning filters applied to the various water systems, Process water systems and industrial cooling water system, bid farewell to a 24-hour continuous operation of a running system, for the "br> suppressed by the impurities in the water to ensure that the system is safe and reliable equipment operation. |

2, structure and working principle
By the filter quality carbon steel or stainless steel cylinder, Johnson strainers, flow direction valve Pressure controller, the electric control box and sewage installations composed. When the filters work "br> pm, the water flow valve in the direction to open state, the water flow from the entrance into the filters, After filtration through strainer into exports. When the filter up pressure on the import and export value, or set the timer to preset time, electrical control box to send a signal that the sewage valve is opened (flow valve at the opening orientation state), Irrigation water filters glued to the "br> wall of impurities from the impurities from the outfall discharge. Steering currents later closed valve (valve in the open sewage state) in the flow direction valve closure process flow continues to increase, and Adhesion In "br> To network of impurities on the inner wall was washed further exhaust valve when the flow direction in the All-state, water filters were forced to imports of mesh strainer into the lateral, most liquid net exports from the "br> outflow part of the net liquid from entering the filter strainer internal lateral (because the pressure relief system in the state, Filter internal pressure is less than the lateral pressure), so as to screen for backwashing. special "br> Johnson network design makes the filters within the spray effects, are any impurities from the smooth on the inside wall washed away. then the import and export filters resume normal pressure or timer settings "br> closed down, electric sewage valve closed Open valve flow direction. Throughout the process, materials flow continuously to achieve a continuous, automated production. |

4, ZJD series of self-cleaning filter electronic control devices "br> 1, ZJD series of self-cleaning filters electrical control by four components :
(1) of differential pressure sampling D520/7DD switched from adjustable differential pressure controller. Differential pressure range of settings 0.02-0.16MPa;
(2) automatic backwash part by the NRV-drive components. The drive, using quality aluminum die box, light weight and excellent heat dissipation properties, load capacity;
(3) sewage in part by the electric valve components, the whole system from a control box controls to achieve manually. Self-cleaning, sewage purposes;
(4) control box part of the introduction of three-phase power supply for the four-wire system (380V 50HZ) 0.15-3kW drive motor power, the control box used waterproof box through the whole screen, the smart structure, access "br> The control box connectors are waterproof connector. Electrical wiring diagram as a (applicable to brush, suck scanning, - Diversion) electrical diagram 2 (applicable to Backwash-type).

2. Some explanations (1) electronic control device debugging steps detailed product instruction;
(2) differential pressure controller settings by adjusting the product instruction set regulation;
(3) cleaning time for 1-24 hours adjustable, which can be used according to the actual work of cleaning time set;
(4) Limit Switch sewage valve factory has been transferred, and not to revise the general, if not in use location, according to a separate manual adjustment.

5, product installation and use of the guidelines
To facilitate maintenance, ZJD series of self-cleaning filter installation should be set up in export valves, and so bypass pipe; To prevent too much debris into the traps, the traps proposal "br> import fixed-strainer.
In addition, attention should be installed on the hull of the flow direction of the arrow with the same direction.
1966 filters installed in several forms for users to install reference. |

6, ordering notes
1. User orders please correct product name, model specifications, the maximum working pressure, temperature, filtering accuracy, material, connecting flange;
2. Motor whether the explosion, whether outdoors;
3. Special requirements will be made;
4. Filtering accuracy choice "br> Generally speaking, filters filtering accuracy of some choices, set on the strength of some large, and the fact that the filters are not speaking the higher the better filtering accuracy, normally as long as can meet the technical requirements,
Especially when the water oil higher accuracy more easily paste network. Therefore, choice of filtration accuracy must be considered when considering, The following parameters for the choice of Johnson strainer accuracy when Participation "br> examination :
(1) ZJDL III Backwash self-cleaning filters, ZJDP diversion - type self-cleaning filters Johnson of the V-filter section to North Korea Foreign sophisticated, accuracy of the filter selection 0.2-0.30mm allowing muddy liquid oil content of less than 10mg accuracy of the filter selection 0.10-0.20mm allowing muddy liquid oil content ≤ 5mg/L;
(2) Brush ZJD series, ZJD series suck scanning self-cleaning filters allow cloud of oily liquid ratio of the above parameters to rise 50%.
5. Front coarse filter "pipeline outage due to the construction and management of the imperfections, In actual operation, usually found enter the pipeline system who have not yet been cleared of debris, such as steel trim first, the first electrode. pieces of wood,
Bricks, stones and rag direct access filters, filters can lead to normal work. To this end, users can import filters installed crude filters, to be suppressed by the big pipe miscellaneous "br> quality. filters to protect the normal operation. (I plant and the production pipeline FB Series filters can be as coarse filters front) |
