Product details

Introduction

The manual brush filter refers to the filter installed on the pipeline to remove the rust, sand and other solid impurities in the fluid, to protect the equipment on the pipeline from wear and blockage, so that the machine equipment: compressor, water pump, valve, instrument, etc. can work and operate normally, to achieve the stability of the process, to ensure the role of safe production.

Its outstanding advantage is that the cleaning process can be carried out during the filter, without removing the tube body, and without affecting the normal operation of the equipment.


Principle

Hand brush filter is a semi-automatic cleaning filter, using the filter screen built-in brush and brush frame, brush the dirt, impurities and other particles on the filter screen, and then discharge through the sewage valve.Its biggest features are:

Cleaning can be carried out in the process of filter operation, without interrupting the flow and without affecting the normal operation of the equipment.


Structure of the material

The filter structure is reasonable, the material is exquisite, the shell adopts high quality carbon steel, but also can use stainless steel according to the user's requirements;Stainless steel brush made of inorganic materials (good elasticity, high strength, corrosion resistance and aging resistance) and stainless steel brush frame composition;Filter mesh for elaborate production of stainless steel wedge mesh, exquisite structure, very easy to brush off the sundry, filtration, cleaning effect is much better than punch mesh or textile mesh, and wash the net when the brush is not easy to damage.Just turn the handle outside the brush holder gently.

Selection principle

1. Inlet and outlet diameter:

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


2. Nominal pressure:

Determine the pressure level of the filter according to the highest possible pressure in the filter line.


3. Selection of orifice number:

Mainly consider the size of impurities to intercept, according to the medium process requirements.Check the following table "mesh size" for intercepting particle size of various specifications of mesh.


4. Filter material:

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


5. Calculation of filter resistance loss

For water filters, the pressure loss is 0.52 ~ 1.2kp at the generally calculated rated flow rate
