Centrifugal fine filter main buyer country

When you see the request 'Centrifugal fine filter main country of buyer', the first thing that comes to mind is statistics. But behind the numbers lies a more complex picture. Many people mistakenly believe that the key market is Germany or the United States, but according to our data, the agricultural regions of Kazakhstan and Belarus have shown steady growth over the past three years. It's therecentrifugal fine filterhas become a critical element of drip irrigation systems.

Why centrifugal filters?

In 2022, we delivered a batch of filters to the Kostanay region. Local agronomists complained about sandy soils - conventional mesh filters failed within a season. I had to adaptcentrifugal filterfor a high content of abrasive particles. We increased the thickness of the rotor walls, but encountered a paradox: the increase in durability led to an increase in energy consumption. I had to look for a compromise.

Interestingly, in Belarus there is another problem - sludge and organic matter. Therefine filtermust cope with suspensions of organic origin. We tested a modification with an additional settling chamber, but this increased the dimensions. In the end, we settled on a combined solution - a centrifugal block plus replaceable polymer meshes.

By the way, about materials. Stainless steel is not always a panacea. In some regions of Uzbekistan, due to the chemical composition of water, even AISI 304 begins to corrode after two years. We had to develop an option with a polypropylene body, although we were initially skeptical about plastic on an industrial scale.

Design solutions for different countries

In collaboration withShandong Linyao Intelligent Agriculture Technology Co.,Ltdwe implemented a project in the Aktobe region. Integration was required therecentrifugal filterinto the existing management system. We connected via the MODBUS protocol, but there were difficulties with calibrating the pressure sensors - local engineers were accustomed to manual regulators.

There is a case on the Mogilev region on the website https://www.lyzhihuinongye.ru. There they used our filter in conjunction with an automation system. An interesting point is that the drainage valves had to be modified because the standard ones became clogged with plant fibers during the algae bloom season.

For vineyards in southern Kazakhstan, a cascade system of threefine filterswith different bandwidths. Not the most economically profitable solution, but it allowed us to reduce the frequency of washing by 40%. Although initial calculations showed only 25% - a pleasant error.

Technical nuances of operation

Inlet pressure is something that is often overlooked. In Kazakhstan, some farms supply water at 6-7 atmospheres, although the design operating pressure of ourcentrifugal filter— 4 atm. For the first six months there were constant complaints about leaks. We figured it out - it turned out that local technicians had removed the safety valves, considering them an 'extra part'.

Thermal expansions are a different story. In Astana, in winter, filters operate in heated rooms, but in summer, the difference between night and day temperatures reaches 20 degrees. The polycarbonate viewing windows cracked in the first winter. I had to switch to acrylic, although it is more expensive.

The frequency of flushing is a controversial issue. In the instructions we write 'when the pressure drops by 0.5 atm', but in practice agronomists rinse once a day, regardless of the indications. It may be worth revising the recommendations - maybe adding a time interval as an additional criterion.

Adaptation to local conditions

Belarus is faced with an unexpected problem - shellfish. The larvae got into the system and were not killed by thefine filter, and IV tubes. We had to install an additional mesh at the entrance to the centrifugal unit, although this slightly reduced the efficiency.

ForShandong Linyao Intelligent Agriculture Technology Co.,LtdWe developed a modification with a reinforced bearing unit - in the Kazakh steppes, frequent sandstorms disabled standard models. We increased the degree of protection to IP68, although this was initially considered excessive for hydraulics.

By the way, about documentation. Translation of technical manuals into Kazakh and Belarusian languages ​​revealed a lot of inaccuracies in terminology. We had to bring in local engineers to make adjustments. It was especially difficult with the term 'centrifugal separator' - it is called differently in different regions.

Economic aspects of choice

The cost of service is a key factor for the CIS. Initially, they offered filters with automatic washing, but in 70% of cases customers asked for a manual option. This is explained by the low cost of labor and distrust of automation. Although our calculations show that automation pays for itself in two years.

Field maintainability is another important consideration. There are no service centers in remote areas of Kazakhstan, so the design had to be simplified to basic elements. For example, we replaced branded bearings with common industrial ones - the service life is shorter, but you can buy them in any city.

Customs nuances. When delivering to Belarus, it turned out to be more profitable to transport components separately and assemble them locally - duties are reduced. But at the same time, quality control of the assembly is lost. We had to train local technicians - we developed video instructions in Russian with subtitles in Belarusian.

Prospects for technology development

We are now experimenting with composite materials for the rotor. Carbon fiber has shown good results in tests, but the cost is still prohibitive for the mass market. Perhaps it will work for the premium segment in the same Kazakh agricultural holdings.

Integration with IoT - there is a request, but the implementation is complex. In the sameShandong Linyao Intelligent Agriculture Technology Co.,Ltdimplemented a monitoring system, but it turned out that in many regions of Kazakhstan there were problems with cellular coverage. I had to add local data storage with synchronization once a day.

Energy consumption is the next area of ​​work. Pumps forcentrifugal filterconsume up to 30% of the total energy of the irrigation system. We are testing recovery systems, but so far the efficiency does not exceed 15% - not enough for commercial use. Although, in the context of rising electricity tariffs, this direction is becoming increasingly relevant.
