Consumable damage

Hello, everyone, when we use the crusher, wearing parts are inevitable things to be used, such as oil seal, inner and outer sleeve, what kind of pin, various screws and so on, let's talk about the advantages and disadvantages of various parts and the impact on the hammer.

Inside and outside.Hammer, as we all know, inside and outside the set is one of the parts wear faster, once the inner and outer casing wear more than the limit, light person knapper don't work well, don't rang rang, when heavy cylinder under scrap, so the inner sleeve than when wear limit must be replaced, in general normal use within a set of service life can reach 2000-3000 hours, but if started with 7 years, a lot of smart people began to use inferior materials to do the inner sleeve, prices vary a lot, of course, also sent a lot of quality, the same SB81 inner sleeve, inferior price about 200-300 yuan or so,Good quality probably 400-500 yuan or so, although the price is poor one time, but the service life of inferior has 500-900 hours only, quality and time limit still have the manpower material resources that consumes which are you willing to choose?

Oil seal.I believe this part is familiar to everyone, many places can be used, the quality of the oil seal directly affects the service life of the parts, especially in the crushing hammer.I don't know if you've noticed that the smaller the hammer and the bigger the hammer, the harder it is to fix. Why is that?Because small hammer drill shank diameter 68.70 to replace oil seal, in particular, the rework probability is about 30%, most of the oil leak, customers usually have a psychological, small hammer was also not make money, some new hammer thousands of pieces, so most of them don't want to spend too much money on hammer, generally change the oil seal even working hours is 200-300 dollars, but if it is pure NOK oil seal, a set of oil seal is more than 200, plus the working hours and after the risk, who are willing to do?This gave birth to the birth of poor oil seal, cheap oil seal a set of only a few dollars, the maintenance worker will generally bet a probability, in case installed not oil leakage I am not to earn?So sometimes it is not that we do not want to use good things, but can not use cheap, there is a demand for the market, and the market determines the quality of product promotion.(note: some breakage hammers leak when it's cold, and we'll talk about how to fix that later.)

Flat pins and pins.Flat pin is relatively common wearing parts in the broken hammer, have no fixed drill rod keep fall off drill rod and drill around the vertical, under normal circumstances, the flat pin to achieve both the requirement of abrasion resistance and toughness and deformation is small, and meet these requirements will have strict requirements on material and heat treatment, the general requirements of carbon steel water quenching, the same benefit to drive, many manufacturers directly change the material to the carbon steel, so as to save the cost of raw materials and not durable, especially the small sizes and a large number of hammer, because the carbon content and quenching of some metal elements organization change is very easy to break and deformation,Once flat pin because be out of shape is knocked in cylinder block do not come out, light expend manpower material resources to hit hard for a long time hard, heavy must use gas to cut flat pin melt away, the other pin on hammer is the same reason.

Author's speech: remember when beginning to do this, no inferior parts, each take a hammer can be used 1-2 years don't move, since 09, cheap parts started flooding the market, customers will tell you that you sell things much more expensive than others, how much money earned him much, slowly, I also began to sell cheap, no way, in order to survive but repair customers, in turn, said hammer soon and we have a problem, I only have a wry smile, good accessories you too expensive, I also have no choice.Now our henan market is almost full of cheap, really want to buy good parts almost can't buy, and really good parts manufacturers because also want to survive, but also to meet market demand, so also have to produce inferior parts.Now, I'd like to buy a 140-hour internal hedge. Do you have it?I'd like to have a one-year warranty on the through bolts. Do you have any?Sorry no, only ordinary!!But really good accessories are not without, there are some manufacturers always adhere to the principle, only the production of good accessories, part of the brand crushing hammer manufacturers supporting, part of the sales in a specialized agency, but because of the price and interests of the problem, it is difficult to buy on the market.I always believe that good products will never be replaced by inferior ones unless the market fails.Can replace, but also only a part of the heart fluky love small cheap did not eat big losses.
