Our factory is a specialized enterprise direct under The Ministry of Machine-Building of China. For decades, we have devoted to development of separation machinery and to design and manufacture of oil delivery equipments to meet demands of separation equipments of developing power industry. In recent ten years, a large quantity of separation equipments and oil delivery equipments provided by our factory have been supplied to important projects at home and exported to more than 20 countries and regions in Latin America Europe, South-eastern Asia. Model ZLSG Automatic Water Strainer is developed on the basis of studying American, Israeli, Italian advanced technique, designed according to various work condition and differential requirement. Main products are Model ZLSG Common Automatic Water Strainer, Model ZLSG-A Differential Pressure Brush Type, Model ZLSG-B Fine Precision Filter Mesh Fast Changed type，Model ZLSG-C Brush Double Discharge Type, Model ZLSG-G Double Discharge, Filter Mesh Fast Charged Type and ZLSG-G Single Discharge, Filter Mesh Fast Changed Type. This manual mainly deals with model ZLSG-B, ZLSG-G and ZLSG-GAutomatic Water Strainer.1.STRUCTUREThe automatic water strainer consists of electric reducer, strainer body, electric slurry discharge valve, differential pressure controller and electric cabinet with PLC programmed controller. It has such actions with automatic filtering, automatic slurry removal, automatic slurry discharge. Normal water supply can be ensured during slurry removal and discharge. The strainer is automatic controlled by programmed PLC, as well as manual controlling is adopted, Safety protection and failure alarm for excessive differential pressure and over-torque protection of discharge valve will come into action in case. So automatic control is realized. 1.1 Model ZLSG-B Automatic Water StrainerModel ZLSG-B Automatic Water Strainer body composed of filter elements (many filter drum are laid on a flange of filter core), Slurry discharge rotary mechanism, slurry discharge pipe, inlet/outlet pipe, tank, examine hole. If filter drum is going to be changed or examined, you can take out easily anyone of them from examine hole at the upper of strainer, No strainer can do so but ours at home and abroad. Their strainers must use a hoist to open the reducer and tank for maintenance. Because of these features, our strainer can be designed to suit for various conditions of different filter fineness requirement. The highest fineness shall be 0.01mm.1.2 Model ZLSG-G Automatic Water StrainerModel ZLSG-G Water Strainer is of lead technique in world. This strainer is the national patented (patent No.: ZL 99 2 41273.0). It is suitable for filtering water containing various floats (sponges, wooden chips, plastic bags and woven bags) and deposits(sand and stone) for automatic filtering, automatic dirt removal and automatic dirt discharge. The water strainer is mainly composed of planetary cycloidal pin gear reducer, body, electric discharge ball valve, differential pressure controller, differential pressure variator and electric system with programmed PLC controller.The strainer body consists of filter assembly(filter drums arranged on filter core circumferentially),discharge moving mechanism, upper and lower discharge pipes, tank, inlet/outlet water pipes, and service access for filter drum on upper tank. The strainer structure is very special. It has following remarkable advantaged:A. Manual service access of filter screen.B. Individual discharge of floats and deposits.C. Automatic reversing motion of over-torque ball valve of discharge valve and automatic stop of over-torque of reducer. D. Automatic counter-flash function.E. Three controls can be obtained ( Automatic, differential pressure and manual control).F. Various kinds of signal control, such as no-power, excessive differential pressure, 4-20mA DC differential analogs, over-torque of discharge valve and failure of reducer and respective protections as no-power protection of water strainer, excessive differential pressure protection, over-torque protection of discharge valve and reducer failure protection can be controlled by computer in general control room.G. Programmed control is based on PLC. So automatic control is realized. Technique advantages:A. Vertical Installation and Upper Inlet/Lower OutletThis structure facilitates deposits to enter fine filter drum. Screen precision design according to requirements enables sands passing through the drum to be discharged along flowing direction. And deposits fails to go through the drum and discharged at discharge port through dirt-holding drum located at the bottom of the body by action of automatic counter-flush water pressure.B. Double Discharge Dirty water cavity and inlet is located upper part of the body to prevent floats entering strainer from going into fine filter drum. Dirty entering the strainer is let out at the discharge by floats discharge valve for inlet cavity. In doing so, blockage of filter drum and discharge moving mechanism is avoided.C. Manual Service AccessManual service access and special design of filter drum ensures that service of fine filter drum can be easily done without hoisting device and disassembling reducer and strainer tank.D. Dirts Discharge of Small Rotary Drum Specially designed discharge mechanism is separated with water cavity and vertically connected with discharge drum, which is bigger than discharge pipe by means of fixed discharge pored frame. External wall of discharge drum is tightly contacted by sealing pieces that are of filler tetrafluoride. This structure reduces friction torque and abrasion and prevents blockage of rotary drum. 1.3 Model ZLSG-G Automatic Water StrainerExcept type of slurry discharge is not similar as ZLSG-G automatic water strainer, which ZLSG-G is double discharge , the ZLSG-G is single discharge. It is the same as the ZLSG-G strainer on structure, function and characteristic.2. Electricity Control 2.1 Slurry Removal Control Type Three slurry removals are following：2.1.1Time Start Reducer and electric slurry discharge butterfly valve are started automatically timely by time relay (if PLC Programmed controller is adopted, the time relay is a PLC internal time relay). Namely, reducer starts as well as slurry discharge valve operate. 2.1.2 Differential Pressure StartDifferential pressure controller automatically controls reducer and electric slurry discharge butterfly valve, and automatic slurry removal and automatic discharge can be realized.2.1.3 Manual Control Start Buttons on electric cabinet controls reducer and slurry discharge butterfly valve manually.When anyone of slurry removal control type above obtains, the strainer will begin to removal and discharge dirt. Namely, the reducer starts and discharge valve opens up. 2.2.Failure Protection FunctionSafety protection and failure alarm will come into action in case reducer failure, excessive torque, excessive differential pressure occurring.2.3. Supervise Control FunctionPLC Programmed Controller will be connected with computer by a special use line, connection and connecting line of computer, then, the supervise control will be realized through a computer. If differential pressure of inlet/outlet needs to be measured, the strainer must installed a differential pressure variator of output analog signals of 4-20mA DC ，and have the variator connect into computer。3.Principle3.1 Model ZLSG-B Automatic Water StrainerDuring normal filtering, electric reducer does not work and slurry discharge valve is closed. When slurry removal is needed, slurry discharge valve is open and reducer starts to drive slurry discharge elements within the strainer and this makes flushed filter elements connect with discharge port respectively and adhesives on screen are backflushed by clean filtered water and discharged through open slurry discharge valve.3.2 Model ZLSG-G Automatic Water StrainerDuring normal filtering, electric reducer does not work and slurry discharge valve is closed. When slurry removal is needed, Lower slurry discharge valve is open and reducer starts to drive moving mechanism strainer and this makes each filter mesh connect with discharge port at bottom of moving mechanism respectively and the upper is closed down. The suspension and deposit on screen are backflushed by clean filtered water and discharged through open slurry discharge valve. When upper discharge valve (deposit discharge valve) opens, reducer doesnt start. The floats at top of tank discharged through open upper discharge valve. 3.3 Model ZLSG-G Automatic Water StrainerDuring normal filtering, electric reducer does not work and slurry discharge valve is closed. When slurry removal is needed, slurry discharge valve is open and reducer starts to drive moving mechanism strainer and this makes each filter mesh connect with discharge port at bottom of moving mechanism respectively and the upper is closed down.
