Approaches to Resolve Leakage of Hydraulic System

1st, wise selection of sealed rubber ring and size of sealed groove



The sealing materials should really be appropriate with rod mill. According to systematic operating strain, the hardness of rubber material is subsequently selected. In an effort to make sealed materials reliable and have long services life, it should have appropriate compression rate and tensile quantity when developing sealed groove. If compression charge is as well huge, the compression tension is increased, if friction is elevated, it might quicker the abrasion of sealed supplies, and the assistance daily life would be shorter. If friction is as well tiny, the sealing function is not good, it is going to cause leakage. On account of simple construction, uncomplicated set up, good sealed feature at the same time as reliable operation, zero-shaped sealed ring won't leak when it really is used as static seal, so it's vastly used. Thinking about enhancement of support existence, designers should certainly keep away from the case which the central line of sealed ring is stretched when developing. As a result, the sealed ring must be selected as per international rule, although sealed groove might also be created as to corresponding specifications.



Second, advisable design of elements and pipeline construction



When developing components, designers should really have directional angle in order to prevent harmful sealed elements when setting up. When folks install sealed ring around the sharp edges and groove elements, they should certainly use protective cover so as never to damage by sealed piece. When installing hydraulic pipeline, individuals might shorten the gap among oil tank and also the operated component as significantly as doable. The elbows of pipelines, specifically rod mills really should be less and fewer so as to reduce the pressure reduction and friction. In hydraulic system, people should really cut down fittings, like Jic Fittings, Weld Fittings and others as several as achievable. 30% to 40% of systematic leakage is brought on by fitting leakage.



3rd, manage oil temperature of hydraulic technique



If oil temperature is also large, lubricate oil film will become thin. If friction power is improved, the abrasion is intensified, the sealed supplies are rapid getting older, which will make them difficult and brittle, it would quite possibly lead to leakage. As a way to boost the cooling effect of oil tank, men and women can boost cooling surface area of oil tank, and separate the oil-out and oil-in inside the oil tank with clapboard. Usually talking, the temperature of hydraulic oil in oil tank is in between fifty five and 65 diploma, the biggest can't be exceed 70??. When the oil temperature of obviously cooling oil is exceeding the permitted value, individuals must create cooling pipe inside the oil tank or install cooling machine on the oil-in highway in order to lower the temperature of hydraulic oil.



Fourth, select the suitable fittings



The commonly-used fittings in hydraulic technique are 3 kinds, particularly, Jic Fittings, Ferrule Fittings and Weld Fittings. These three sorts of fittings are respectively attribute, so persons should certainly select them as per the functioning reliability and economical function. Jic Fittings are rather low cost, Ferrule Fittings can bear relatively large vibration, and Weld Fittings can stand up to the circumstance with large pressure, higher temperature also as big-bearing and big-vibrating machinery.



5th, strictly manage the produced high quality



Individuals really should strictly control the tolerance of sealed groove, and also the area roughness will have to be in accordance with necessity of drawing. The groove edge cannot have burrs and bumps, persons should really thoroughly clean it prior to installation. In addition, folks will need to make certain the good quality of sealed go over size and flange screw, the gap can not be also huge so as to stay clear of squeezing by sealed piece.



Moreover, through the manufacturing, people today have to intensify the upkeep and conduite, and they've to frequently check out, mend and guard hydraulic gadget in an effort to stay clear of the mechanical effect and impact stress. And folks must discover out the leakage soon enough so as to lessen the failures and oil leakages, prolong assistance life of machine too as enhance the superior issue of gadget.
