Lianshenghuakang brand industrial water filters and filter equipment are divided into rotary backwash type water filters and rotary backwash strong discharge secondary filter screens. Their rotary backwash type water filters are well used in the following industrial manufacturing and production: circulating cooling water systems in thermal power plants, hydropower stations, petrochemicals, steel smelting, printing and dyeing, papermaking and textile industries, heating network water systems and other water supply pipelines.

Precision laser drilling filters, precision laser drilling water filters, precision laser filters, and precision laser filters have been well applied in the following industrial manufacturing and production: circulating cooling water systems in thermal power plants, hydropower stations, petrochemicals, steel smelting, printing and dyeing, paper and textile industries, heating network water systems, and other water supply pipelines. The stainless steel precision laser drilling filter and filter screen are a new type of stainless steel plate laser drilling filter screen developed according to the "25 Key Requirements for Preventing Major Accidents in Power Production" of the State Power Corporation. At the same time, this type of product can also be used in systems with high filtration requirements, such as the turbine oil system in power plants.

LD type electric rotary backwash industrial water filter

Before the pipeline of the water supply system, a filter screen is usually used for treatment. However, there are still some small-sized impurities in the treated water quality, such as small particulate suspended solids, sediment, snails, etc. When they accumulate to a certain extent in the water supply system and are not cleared, it will lead to a reduction in the flow area, blockage, and in severe cases, shutdown, posing a great threat to safe operation. So it is necessary to install industrial water filters and water purifiers on small diameter pipelines.
The LD type electric rotary backwash industrial water filter has the following advantages:
1: Small in size, convenient for on-site layout and installation.
2: The material and structure of the mesh board maximize the flow area of the water, effectively reduce the water resistance of the filter screen, ensure reliable operation without jamming, blocking, or blockage, and greatly extend the filter screen.
3: The filter screen is formed by integral stamping of 3-6mm stainless steel plate, and the core should be able to withstand a differential pressure of 150 kPa without deformation or damage. It has the characteristics of long working life, corrosion resistance, no rust, smooth surface, and no scaling.
　

LS type manual rotary backwash industrial water filter
Considering various factors such as economy, convenience, maintenance, and spatial installation location, the characteristics of the new LS type manual rotary backwash industrial water filter series products are to meet user requirements and completely solve the above problems.
The LS type manual rotary backwash industrial water filter is installed on the water supply pipeline, with many advantages such as simple structure, small space occupation, low cost, large filtration flow rate, and high accuracy (the filtration accuracy can be selected by the user, usually Ø 2-Ø 7mm). It is particularly suitable for branch pipelines supplying water to the main pipeline, thus having advantages that backwash type secondary filters and secondary filters cannot match.


LQ fully automatic backwash industrial water filter
The fully automatic backwash industrial filter is a new generation of water filter. LQ filter, also known as self-cleaning filter, fully automatic cleaning filter, fully automatic backwashing filter, automatic backwashing filter, fully automatic backwashing filter, fully automatic self-cleaning filter, fully automatic backwashing filter screen, fully automatic backwashing industrial water filter, fully automatic sewage filter, automatic cleaning machine, automatic flushing machine, water filter, etc. It is an ideal product to replace intermittent water supply filters!


JL type precision laser drilling water filter, precision laser filter screen
The characteristics of precision laser drilling water filter: high safety. Thoroughly eliminated the hidden danger of internal cold water line rod blockage caused by the breakage of conventional filter metal wrapped and non-metal wrapped filters. 2. High precision and good uniformity. Due to the use of laser drilling, the mesh accuracy and uniformity exhibit a very regular and burr free characteristic. 3. For large generators and turbine oil systems, the final filtration can also serve to block debris from the front filter screen. So it also applies to power plant oil systems. 4. High strength and corrosion resistance. The high-quality material of the laser mesh ensures stable operation under high-intensity and high impact water flow, while also having excellent corrosion resistance. 5. The minimum diameter of micropores can reach 0.1mm (100 μ m; 150 mesh/square inch), but considering factors such as water resistance, it is generally recommended to choose 0.3mm to 0.7mm.

EXF type rotary backwash strong discharge secondary filter screen
The secondary filter system is an indispensable device for purifying pollutants in water, maintaining the cleanliness of the condenser water chamber, ensuring the normal operation of rubber balls, and improving the recovery rate of rubber balls. However, the environment in China is relatively serious, especially the water pollution of rivers and lakes. Therefore, the fixed and rotating negative pressure backwash secondary filters commonly used in open cooling water circulation systems have shown their shortcomings. Our factory is a designated factory for the production of power auxiliary equipment. Through continuous solicitation of opinions from users and repeated trial production and continuous improvement of secondary filters in recent years, we have retained some structures of old products, added electric devices, and strong discharge devices to improve the structure and usability of secondary filters. They have been widely used in the open circulation system of cooling water for 6MW to 300MW thermal power generation units and have received unanimous praise from new and old customers.
