Recently, the author communicated with the project manager of an engineering company. When referring to the current scraper type self-cleaning filter on the market, he proposed the problems of this paper and gave Yiqing fluid good advice and hope;

The filter manufacturers are quite mixed. In the past two years, the common mechanical (scraper) self-cleaning filters in the market have enjoyed rapid market penetration, but many feedback problems have been mentioned, as mentioned in the title of this article.

The author analyzes that multiple reasons may reduce the customer's experience of use:

1. Inaccurate selection, large output, low capital, high precision requirements, and complex working conditions, and hope to spend more money to do more things; unscrupulous filter manufacturers cater to unreasonable requirements, first to get the list again;

2, filter products failed, the filter opening rate is too high or too low, the accuracy of deviation, the cleaning device can not effectively clean up impurities, in pursuit of filtration capacity, one-sided increase the hole rate and cleaning frequency, sealing problems;

3, the filter design does not meet the principle, scraper, brush used together, even with recoil function, the sewage outlet is located in the side of the filter to form the second plug filter impurities, sewage outlets and even the top of the filter, the control box settings, blindly Adopt the principle of differential pressure, etc.

4, the operation is not correct, most of them do not have a complete operating procedure, and the lack of production separation process before and after filtration;

5, sales service is not professional, most of the filter manufacturers of technical personnel only drawing, behind the door to build a car; sales staff instill inexplicable concepts in front of the customer, get the customer to leave after the winner;

6, the demand is not clear, that adding a simple filter, you can solve the solid-liquid separation problem in the entire process;

Conclusion: The high-quality EJS self-cleaning filters and systems are only available to innovative customers.
