stainless steel filter

2020-03-25

 

Common stainless steel filters are divided into bag type, core type, Y type filter, stainless steel rod telescopic filter, T type stainless steel filter, stainless steel U type pipeline filter, stainless steel basket straight-through filter, stainless steel double barrel filter, Stainless steel hand brush filter, flange type stainless steel filter, wire mouth stainless steel filter, stainless steel gas filter, stainless steel magnetic filter, stainless steel straight plate filter. And other types.
 
The stainless steel filter is composed of a housing, a backwash mechanism, and a differential pressure controller. The internal cavity of the stainless steel filter housing is divided into upper and lower chambers by a horizontal partition. A backwashing suction cup is installed in the lower chamber.
 
The filter is composed of simplified Chinese, stainless steel screen, sewage part, transmission device and electrical control part.
 
Working principle:
 
During operation, the liquid has an inlet flowing through the filter screen, and enters the pipeline required by the user through the outlet for the process cycle. The acrobatics in the water are trapped inside the filter screen. There are more and more particles left by the liquid circulation, and the filtration speed is getting slower and slower, while the imported sewage still enters continuously, and the filter pores will become smaller and smaller, thus creating a pressure difference between the inlet and the outlet. When the degree difference reaches the set value, the differential pressure transmitter sends a signal to the controller, the controller starts the drive motor to drive the shaft through the transmission component, and at the same time, the sewage outlet is opened and discharged from the sewage outlet. After the filter is cleaned, the pressure The difference drops to the minimum value, the filter returns to the initial filtering working state, and the system is operating normally.
 
Concise technology:
 
Determine the pressure level of the filter according to the highest possible pressure in the filter line.
 
The material of the filter is generally the same as the material of the connected process pipe. For different service conditions, you can choose a filter made of cast iron, carbon steel, low alloy steel or stainless steel.
 
Water filter, under the general calculated rated flow rate, the pressure loss is 0.52 ~ 1.2kpa
 
1. Working pressure: 1.6-2.0Mpa
 
2. System pressure loss: 30-50Kpa
 
3. Working temperature: 2.95 ℃
 
4. Filter aperture: 50-1000μm
 
5. Rinse time: about 23 seconds for single cycle of backwash
