Electric Industrial Water Filter

Considering economic, convenient, and maintenance factors, Guanghe Power Equipment Co., Ltd. has designed and manufactured a new series of industrial backwash filter water systems that meet user requirements and thoroughly address the aforementioned issues.

I. Advantages of the Product:
1. Simple structure, occupying minimal space.
2. Low cost (refers to manual backwash type).
3. High flow rate with high filtration accuracy.
4. Fully Automatic Water Filter (More expensive than manual models)
This model features an imported PLG programmable control system, remote control, and is equipped with an online differential pressure monitoring system. The equipment is also capable of manual, timed, and automatic cleaning functions.
5. Applicable Impurities: Silt, industrial waste, weeds, plastics, fish and shrimp, snails, algae, etc.
6. Innovative design, long service life.

Section II: Filter Structure
This water filter is composed of ①rotary pump, ②locating rod, ③supporting shell, ④filter core, ⑤inlet, ⑥outlet, and ⑦drainage port. It also includes an electric reducer and an electrical cabinet.
Water quality is generally freshwater type, with the filter and main internal components made of stainless steel. For seawater and other strongly acidic or alkaline types, it is recommended to use special stainless steel materials for parts in contact with the medium.

1. Differential Pressure Backflushing: When impurities accumulate to a certain amount, a backflushing and drainage process is initiated using the differential pressure signal between the cooling water inlet and outlet pipes. This involves connecting the electrical contact pressure gauge to control signals, which then activate the electric drainage valve. The electric reducer operates at a speed of 3-6 rotations per minute, reversing the flow of water to flush impurities adhering to the inner wall surface of the mesh core. The waste is then discharged through the drainage pipeline and valve into the cooling water outlet pipe, taking approximately 5-10 minutes for a complete cleaning and drainage cycle. In the event of large debris that prevents the filter mesh from operating properly, the electric unit should run in the opposite direction to flush out the debris.
2. Users can set the effluent time if needed, from 0 to 99 hours, to determine the cleaning and effluent schedule. Typically, effluent is set to occur every 12 hours, which can be adjusted according to the water quality of the power plant. The electric reversing reducer is activated at the set time to reverse, opening the effluent valve and proceeding with the backflushing and effluent process. This continues until all compartments are backflushed, at which point the electric unit stops, and the electric backflush and effluent valves are closed, marking the end of the effluent operation.

IV. Water Filter Installation and Precautions:
1) Industrial water filters can be horizontally installed at the condenser inlet or at the circulating pump outlet, with the same effect.
2) The length of the filter screen import straight pipe section should be greater than the diameter of the recirculating water pipeline.
3) Do not tilt during installation; connections must be secure.
4) Maintain a clearance of over 100mm between the filter screen and the condenser's circulating water inlet pipe. Additionally, install a compensating joint between the filter screen and the condenser for ease of maintenance, disassembly, and compensation.
5) After installation, all debris in the recirculation water pipe in front of the filter screen must be cleared. Before putting into operation, conduct a running test.
