●組合形式：
若干個過濾單元并聯(lián)，形式JY系列盤片式過濾器。
基本組合有JY2-3～5（3～5個2"過濾頭）；JY3-3～10(3～10個3"過濾頭)共11種組合方式。
●工作原理：
JY過濾器分JY2（2"）、JY3（3"）二種基本過濾單元，其中過濾芯是由一組帶溝槽棱邊形成的交叉點把水中固體物截留。由于同時具有表面攔截和濃度凝聚的作用，大大提高了過濾效果.
●工作狀態(tài)
過濾盤片在彈簧力和水力作用下被緊密地壓在一起。當含有雜質(zhì)的水通過時雜質(zhì)顆粒被截留。
●反洗狀態(tài)
控制器控制閥門改變水流方向。盤片被松開，位于盤片中央的噴嘴沿切線噴射，使盤片旋轉(zhuǎn)，盤上截留的固體物被沖洗出去。

如果來水壓力低，不足以滿足反洗要求，可采用外接反洗水源JYF系列或增加出口主閥的方式，保證盤式過濾器的正常運行和反洗。
●選型設(shè)計
每個過濾單元（3"或2"）,針對不同的原水水質(zhì)和不同的出水精度要求,其產(chǎn)水量也是不同的(參見參數(shù)表)
一般把原水水質(zhì)分成四類：
A、優(yōu)良水質(zhì)：城市自來水，從穩(wěn)定的含水層抽取的井水；
B、一般水質(zhì)：循環(huán)準冷卻水，經(jīng)沉淀處理過的地面水，經(jīng)過有效沉淀和完全生物篩過的排水；
C、較差水質(zhì)：從水質(zhì)很差的含水層抽取的地下水，經(jīng)過有效沉淀，但未經(jīng)或經(jīng)很少的生物處理的排水，有微生物大量繁殖的地面水；
D、很差水質(zhì)：從很臟或富含鐵錳的井中抽取的井水，受洪水影響且未經(jīng)沉淀的地面水，未經(jīng)沉淀及生物處理的排水。為保證過濾系統(tǒng)較好的工作狀態(tài)，D類水質(zhì)需要進行預處理以提高一個等級。

Disc filter
● Product Features:
1. Precise filtration: Filter discs with different precision can be selected according to water requirements, and there are 20μ, 50μ, 100μ and 200μ specifications.
2, efficient backwash: high speed and thorough backwashing, complete only in about 20 seconds.
3, fully automatic operation, continuous working: in the filter set, the backwash process alternately, between the work, backwash state, automatic switching, to ensure continuous water. The system has a small pressure loss.
4. Standard: Standard module system design, users can choose according to needs, flexible and interchangeable.
5, non-standard: flexible use of corner space, suitable for local installation, occupying a small area.
6, reliable operation and maintenance is simple: almost no daily maintenance, 100% of the parts are tested and commissioned by the factory, no special tools are required, and there are few spare parts.
7, long service life: high-tech plastic filter core is strong, no wear, no corrosion, after many years of industrial practical verification, filtration and backwashing effect will not deteriorate with the use of time.
● Combination form:
Several filter units are connected in parallel to form the JY series disc filter.
The basic combination includes JY2-3~5 (3~5 2" filter nozzles; JY3-3~10 (3~10 3" filter nozzles) a total of 11 combinations.
● working principle:
JY filter has JY2 (2") and JY3 (3") basic filtering units. The filter element consists of a set of intersecting points formed by grooves and edges to trap solids in the water. Because of the function of surface interception and concentration condensation, the filtering effect is greatly improved.
● working state
The filter disks are tightly packed together by spring and hydraulic forces. Impurity particles are trapped when water containing impurities passes through.
● backwash state
The controller controls the valve to change the flow direction. The disc is released, and a nozzle located in the center of the disc sprays along the tangent line, causing the disc to rotate and the solids trapped on the disc to be washed out.
● technical parameters
Working pressure: 0.25 ~ 0.8mpa
Backwash pressure: 0.15 ~ 0.6mpa
Backwash time: 5 ~ 20 seconds adjustable
Backwashing water consumption: 30 ~ 100 l (single filter nozzle)
System pressure loss: 0.001 ~ 0.08MPa
Operating temperature: 4 ~ 75℃
PH: 4.0 ~ 13
JYF series instructions:
Working pressure: 0.08 ~ 0.8mpa
Backwash pressure: 0.15 ~ 0.6mpa
Backwash inlet valve: Copper valve 2 "BSPT screw thread
Number of filtering units: 2 ~ 8
If the incoming water pressure is low and insufficient to meet the backwashing requirements, If the incoming water pressure is low enough to meet the requirements of backwashing, JYF series external backwashing water source can be adopted or the main outlet valve can be added to ensure the normal operation and backwashing of the disc filter.
●Selection design
Each filter unit (3" or 2") has different water production rates for different raw water quality and different water discharge accuracy requirements (see parameter table)
The raw water quality is generally divided into four categories:
A. Excellent water quality: urban tap water, well water drawn from a stable aquifer;
B. General water quality: circulating quasi-cooling water, surface water treated by sedimentation, drainage after effective sedimentation and complete bio-screening;
C. Poor water quality: Groundwater extracted from aquifers with poor water quality, after effective sedimentation, but without or with little biological treatment of drainage, there is surface water in which microbes multiply;
D. Very poor water quality: well water extracted from well-dirty or iron-manganese-rich wells, surface water affected by flooding and not precipitated, drainage without sedimentation and biological treatment. In order to ensure a good working condition of the filtration system, Class D water quality needs to be pretreated to improve one level.
● equipment material
JY filter nozzle is made of reinforced polyamide plastic, anticorrosive and wear-resistant, and can withstand working pressure of 0.8mpa.
The filter plate is made of polypropylene plastic, the seal is EPDM, and the water inlet and outlet channels are made of stainless steel.
