Methods to Solve Leakage of Hydraulic Program

1st, sensible selection of sealed rubber ring and dimension of sealed groove



The sealing supplies might be appropriate with rod mill. Based on systematic working strain, the hardness of rubber materials is thus selected. As a way to make sealed supplies dependable and also have extended provider lifestyle, it should certainly have suitable compression amount and tensile quantity when designing sealed groove. If compression price is also large, the compression pressure is improved, if friction is increased, it might faster the abrasion of sealed supplies, along with the support daily life could be shorter. If friction is too smaller, the sealing function is just not excellent, it is going to trigger leakage. Because of simple construction, quick installation, very good sealed function at the same time as reliable operation, zero-shaped sealed ring won't leak when it really is utilised as static seal, so it's extensively employed. Taking into consideration enhancement of services existence, designers ought to prevent the case which the central line of sealed ring is stretched when designing. Consequently, the sealed ring really should be selected based on global rule, while sealed groove will need to also be designed with regard to corresponding requirements.



Second, justifiable design of elements and pipeline structure



When creating components, designers might have directional angle in order to steer clear of damaging sealed components when installing. When people install sealed ring around the sharp edges and groove components, they really should use protecting cover in order not to damage by sealed piece. When setting up hydraulic pipeline, individuals should shorten the space among oil tank plus the operated part as a lot as probable. The elbows of pipelines, primarily rod mills should be less and fewer so as to reduce the pressure reduction and friction. In hydraulic system, persons should certainly reduce fittings, like Jic Fittings, Weld Fittings and others as several as feasible. 30% to 40% of systematic leakage is brought on by fitting leakage.



3rd, control oil temperature of hydraulic program



If oil temperature is too higher, lubricate oil film will turn into thin. If friction force is improved, the abrasion is intensified, the sealed supplies are fast getting older, which will make them difficult and brittle, it will quite possibly result in leakage. In an effort to enhance the cooling effect of oil tank, folks can increase the cooling surface of oil tank, and separate the oil-out and oil-in inside the oil tank with clapboard. In most cases talking, the temperature of hydraulic oil in oil tank is among fifty five and 65 degree, the best can't be exceed 70??. Once the oil temperature of effortlessly cooling oil is exceeding the permitted worth, people today will need to create cooling pipe within the oil tank or set up cooling device around the oil-in highway so as to lower the temperature of hydraulic oil.



4th, pick the suitable fittings



The commonly-used fittings in hydraulic program are three types, particularly, Jic Fittings, Ferrule Fittings and Weld Fittings. These three forms of fittings are respectively characteristic, so individuals will need to pick them in accordance with the operating reliability and affordable function. Jic Fittings are pretty low cost, Ferrule Fittings can bear comparatively massive vibration, and Weld Fittings can endure the situation with substantial stress, large temperature too as big-bearing and big-vibrating machinery.



Fifth, strictly manage the manufactured excellent



Folks will need to strictly manage the tolerance of sealed groove, and also the surface roughness will have to be in accordance with prerequisite of drawing. The groove edge can't have burrs and bumps, folks should certainly completely clean it prior to set up. What's more, people should guarantee the quality of sealed go over dimension and flange screw, the gap can't be as well massive in order to avoid squeezing by sealed piece.



In addition, during the production, individuals need to intensify the upkeep and management, and they've to regularly check, mend and protect hydraulic device in order to refrain from the mechanical impact and influence pressure. And men and women need to locate out the leakage in time so as to lessen the failures and oil leakages, extend company daily life of device as well as enhance the good problem of device.
