Stainless steel mesh series - Mesh screen how should we carry out maintenance and maintenance?

Before we use a device to process and purify, we need to install filter elements, among which the stainless steel filter series is the most. Today, let's learn about the stainless steel filter series - filter mesh we should how to carry out maintenance and maintenance?

The edge of the filter mesh is first checked by visual inspection filter material defects, cracks and holes in the phenomenon, check whether the combination of frame Angle is sealed, there is no gap, etc., after the detection of qualified filter can be used. Determine the airflow direction of the filter under test according to the direction indicated by the arrow, and see whether its upper and lower positions are correct. Adjust the temperature in the whole system to reach °C, and the relative humidity is about 75%. Start the fan of the testing equipment, adjust the frequency converter of the fan and the valve at the end of the air duct, so that the air volume in the air duct can reach the required air volume for the test.

Secondly, we measure the resistance of the filter section on the micropressure gauge, and subtract the resistance of the filter from its value, and the result is the resistance of the filter. If problems are found in the use of the testing equipment, the parameters of the generator should be adjusted according to the content in the product manual to maintain stability. We will say that the following parameters need to be set before formal detection: optical particle count rate: With the generator and the filter under test in place, check the background count rate by measuring the particle count concentration downstream of the device. Air cleanliness: With the generator turned off, the cleanliness of the air is checked by measuring the concentration of particles upstream. Upstream and downstream sampling: When the generator is turned on, the number and concentration of particles upstream and downstream of the device are measured respectively, so as to calculate the correlation coefficient standard of upstream and downstream sampling.

Finally, after using the filter for a period of time, we need to remove the filter products in time for maintenance and cleaning, otherwise the flow rate and the filtration quality of the products will be greatly affected.
