Hand brush filter

Hand brush filterIt is an efficient filtering device used during pipeline transportation to filter and remove impurities from the medium in the pipeline.

Introduction

Hand brush filterIt refers to the installation on pipelines to filter out solid impurities such as rust and sand particles in fluids, protect equipment on pipelines from wear and blockage, enable machinery and equipment such as compressors, pumps, valves, instruments, etc. to work and operate normally, achieve stable process, and ensure safe production.

Its outstanding advantage is that the cleaning process can be carried out during the filter without disassembling the pipe body, which does not affect the normal operation of the equipment.

principle

Hand cranked brush filter is a semi-automatic cleaning filter that uses the brush and brush holder built into the filter screen to remove dirt, impurities, and other particles from the filter screen, and then discharges them through the drain valve. Its biggest feature is:

Cleaning can be carried out during the operation of the filter without interrupting the normal operation of the equipment.

structural material

The filter has a reasonable structure and high-quality materials. The shell is made of high-quality carbon steel, and stainless steel can also be used according to user requirements; The stainless steel brush is made of inorganic materials (with good elasticity, high strength, excellent corrosion resistance and aging resistance) and composed of a stainless steel brush holder; The filter screen is made of carefully crafted stainless steel wedge-shaped mesh, with a sophisticated structure that is very easy to brush away debris. The filtering and cleaning effect is much better than punching mesh or textile mesh, and the bristles are not easily damaged when washing the mesh. To use, simply gently rotate the handle on the outside of the brush holder.

Technical Specifications

Work pressure: ≤ 1.0Mpa (if higher work pressure is required, please specify when ordering)

Pressure loss force: ≤ 0.015Mpa

Filtering accuracy: 0.8 mm (can be manufactured within the accuracy range of 0.2~3.5mm)

Maximum operating temperature: ≤ 100 ° C

Selection criteria

1. Import and export diameter:

In principle, the inlet and outlet diameter of the filter should not be smaller than the inlet diameter of the matching pump, and generally consistent with the diameter of the inlet pipeline.

2. Nominal pressure:

Determine the pressure rating of the filter based on the maximum pressure that may occur in the filtering pipeline.

3. Selection of pore size:

The main consideration is the particle size of impurities that need to be intercepted, depending on the process requirements of the medium flow. The particle size that can be intercepted by various specifications of wire mesh can be found in the table "Filter Screen Specifications".

4. Filter material:

The material of the filter is generally chosen to be the same as the material of the connected process pipeline. For different service conditions, filters made of cast iron, carbon steel, low-alloy steel, or stainless steel can be considered.

5. Filter resistance loss calculation

Water filters have a pressure loss of 0.52-1.2kp at a generally calculated rated flow rate
