In the process of daily reception customer, often will meet some customers ask dh filter, pall filter, 3 m filter foreign brands such as filter, also often meet with some clients will ask what the difference between real import filter and domestically produced generic filter, now, we production experience for many years to describe simple:
how to identify to distinguish the original dh filter and domestic dh filter?
dh filter is an indispensable part of conveying medium in pipe series, usually installed in the hydraulic system in the inlet side of the filter, used to filter the fluid medium metal particles, pollution, impurities and so on, can the normal work of the protection equipment operation, after the fluid into the filter, the impurity is blocked, and clean the filtrate by filter outlet. When need to be cleaned, as long as the filter from the filter, with industrial liquid treatment after loading.
dh filter is a big brand of hydraulic oil filter, is a product of dh company in Germany, is also a lot of power plants, steel mills, paper mills, etc are very commonly used a brand of filter, because dh filter customers range is wide, the user is more, so many of the domestic filter according to the original factory of dh technology and specification to production. Original dh filter adopts imported glass fiber/stainless steel wire mesh is made in the United States, has a convenient draining, big flow area, small pressure loss, simple structure, small volume, light weight, filter material evenly, and so on.
2. Original dh filter the compatibility of the filter material is suitable for general hydraulic oil filter.
3. On either side of the original dh filter by solid and strong stability of filtering material, accord with ISO3724/76 hydraulic filter validation of current fatigue characteristics.
imported from dh filter compared with domestic alternative to dh filter still have certain difference, so should be how to distinguish the original dh filter with domestic dh filter? We mainly look at the following:
1, can be viewed from the outside of the filter itself, although dh filter is manufactured goods is not art, but the dh filter with domestic or imported from a big difference, while the domestic alternative to dh filter manufacturer has many, but compared to the original factory product dh, a large number of domestic manufacturers or reach the level of the original, so also is able to distinguish true and false, from the appearance of the original dh filter packing and filter itself is fine workmanship, because the present domestic most of the manufacturer of dh filter is made by hand, it is difficult to achieve the effect.
2, directly from the filter filtering effect to distinguish, ordinary precision filter is not obvious, but high precision filter from the point of filtering effect, general domestic filter is difficult to achieve, if the precision of the original filter in 1 micron, homebred filter filtration material chooses import may reach about 3 micron, if domestic filter material is short of original dh filter filtration precision, but the general hydraulic oil filter precision is not very high, so domestic dh filter in many cases can meet the demand of filtering, and whether it is original dh filter or domestic dh filter filtration efficiency are need specialized testing institutions to test out, for the average user is difficult to test.
3, and is the price of the filter element, the original dh filter with domestic dh filter also has a certain difference in price, but not all domestic filter prices are much cheaper than the original, there are many domestic dh filter manufacturers to covet the maximization of profits, with domestic dh filter ACTS as the original, the customer is sometimes hard to distinguish.
the place on put together is narrated, in today's market in our country, if you want to buy the real original installation import filter, filter or advise clients don't want disorderly to find, because a lot of bad business with high copy of the filter when the original sale, general customer experience is very difficult to distinguish true and false, is the best way to go to foreign manufacturers of domestic offices.
with the development of industrial technology, made in China have already thoroughly remould oneself, already break the monopoly of foreign products, filter, henan science and technology co. , LTD. , after many years of honed, has a complete set of production technology and advanced production lines, welding and machining technology has reached the level of some brands abroad, at the same time, adopt the original installation import filter material, the production of filter already completely replace most of the imported filter, relative to the import filter, filter has a short production cycle, timely delivery, low price advantage, will inform the customer at the same time the production of filter for alternatives, not original, filtering is to use the actual product quality by customers, not by cheat customer, hope can get the trust of many customers.
