Y-type Self-cleaning Strainer
1 Product Overview
Y-type Self-cleaning Strainer is a pressure-bearing fully automatic electric brush filter. Fluid enters Y-shaped chamber, particles larger than nominal rating are trapped on outer surface of metal screen. Contaminant buildup raises inlet-outlet differential pressure and triggers cleaning cycle. Gear motor drives brush rotating to sweep screen, electric blowdown valve opens simultaneously for sludge discharge. Pipeline flow remains uninterrupted during whole cleaning process.
Differentiated from Hand Brush Y-type Strainer: equipped with motor and automatic control cabinet, no manual crank rotation required for fully automatic cyclic cleaning.Compared with vertical self-cleaning filters, inclined Y layout features shorter overall dimension, suitable for pump rooms and skid packages with limited vertical installation space.
2 Main Structural Composition
Y-type Pressure Vessel AssemblyEpoxy coated carbon steel / SUS304 / SUS316L inclined cylinder with flanged nozzles.
Metal Screen AssemblyStandard 316L wedge wire screen; stainless woven cartridge optional.
Electric Brush Cleaning AssemblyGear drive motor, transmission shaft, wear-resistant nylon / stainless steel brush frame.
Electric Blowdown Valve AssemblyElectric or pneumatic drain valve synchronized with cleaning sequence.
Intelligent PLC Control SystemDP transmitter, operation panel, alarm & remote signal output module.
Shaft Seal AssemblyEPDM / FKM gaskets to prevent medium leakage at drive shaft.
Support BaseSteel frame for stable equipment installation.
3 Working Principle
Filtration ModeFluid enters Y-shaped chamber and permeates inward through screen. Solid contaminants are retained on outer wall; clarified water flows downstream through outlet, gradually forming filter cake.
Automatic Cleaning ModeFilter cake buildup raises differential pressure to preset threshold or timing cycle expires, automatic cleaning activates:Drive motor rotates brush for circumferential screen sweeping; blowdown valve opens to discharge stripped sludge under pipeline pressure. When cleaning duration expires, valve closes and motor stops; filter resumes normal filtration. The cycle runs automatically in loops; manual override mode is available on demand.

5 Core Product Advantages
Compact inclined Y structure, perfect for narrow pump rooms and skid-mounted units.
Fully automatic electric brushing with uninterrupted flow for continuous water supply.
Three control modes supported for linkage with remote automation systems.
Reusable permanent metal screen eliminates recurring consumable expenditure.
Automatic operation reduces daily manual inspection workload.
Wedge wire screen offers outstanding anti-clogging performance for fiber and sludge laden raw water.
Low blowdown volume reduces long-term water consumption.
Diversified material options fit fresh water and mildly corrosive industrial media.
Simple and robust construction with low failure rate and easy maintenance.
Parallel installation available for capacity expansion of large-flow systems.
6 Installation, Commissioning & Maintenance Specification
Install strictly following flow marking, arrange screen chamber inclined downward for sediment settlement. Reserve minimum 5×DN straight pipe sections upstream and downstream.Isolation valves and bypass are recommended for offline maintenance. A coarse strainer upstream is suggested to avoid heavy debris damaging screen.Flush internal welding residues before initial water filling. Set cleaning differential pressure, single-cycle duration and cleaning interval parameters during commissioning.Routinely inspect electric signals, motor noise and valve actuation. Annually check brush abrasion and gasket aging status.Run one complete automatic cleaning cycle and drain residual water before long shutdown to prevent sludge hardening and screen corrosion.
7 Common Faults & Solutions
DP rises rapidly with increased cleaning frequencyCauses: excessive inlet suspended solids; damaged screen; insufficient upstream pretreatmentSolutions: install upstream coarse filter; repair or replace screen; optimize front-end water treatment
DP cannot recover after cleaning, unsatisfactory sweeping performanceCauses: worn brush with excessive clearance; solidified sticky contaminants; insufficient blowdown flowSolutions: install new brush; extend cleaning duration; unclog blowdown pipeline
Medium leakage at transmission shaftCauses: aged shaft seal; insufficient packing lubrication; worn shaft surfaceSolutions: replace sealing components; replenish packing lubricant; overhaul transmission shaft
Motor overload alarm and stiff rotationCauses: foreign object jamming screen; misaligned transmission shaft; insufficient lubricationSolutions: open cover and remove bulk debris; adjust shaft concentricity; replenish lubricant regularly
Leakage at flange & end cover jointCauses: aged gasket; uneven bolt tension; damaged sealing surfaceSolutions: install new gasket; tighten bolts diagonally; rework sealing face
