During work, main oiler and each auxiliary oiler are connected with the fuel tank in hydraulic system, oil-out and hydraulic pressure system
The entrance connection of the oil pump in system.Specific work process is as follows：Start oil pump, under the effect of pumping of oil pump, the oil in fuel tank
Liquid enters the first gap through main oiler and each auxiliary oiler, then successively through in the first gap, each valve opening, tubular valve element
Chamber enters the inner chamber of filter core, is then filtered through filter core.A fluid part after filtering is successively through the second gap, third space
Oil-out is reached, another part reaches oil-out, then enters through oil-out through the second gap, third space, the 4th gap successively
Enter oil pump, be achieved in the filtering of fluid.In the process, if environment temperature is relatively low, then heating tube is started, heating tube is to filter
The fluid in in-core chamber is quickly heated, and thus avoids the viscosity of fluid from reducing, so as to the mobility for avoiding fluid is deteriorated, and then
Fluid is avoided to increase by the resistance of filter core.If filter core is blocked, then loop fastener head is pulled using spanner, thus will added
Heat pipe is backed out and extracted out from screw.Now, under the reset response of spring, spring promotes tubular valve element, filter core, end cap together
Motion upwards, so that each valve bore closure（I.e. each valve opening is no longer connected with the first gap）, it is achieved thereby that fluid
It is self-styled（I.e. fluid cannot enter the inner chamber of tubular valve element by each valve opening）.Then, filter cover is unloaded from the second filter cylinder, then
Filter core is taken out and changed.If filter core cannot be changed in time after blocking, then each by-passing valve, filter core inner chamber are opened
Fluid successively through each by-passing valve, the 4th gap reach oil-out, then enter oil pump through oil-out.Based on said process,
Compared with existing oil absorption filter, a kind of self-sealing oil absorption filter with heating function described in the utility model is by using
Brand new, realizes the fluid when environment temperature is relatively low to filter core inner chamber and is quickly heated, and thereby ensures that in environment
Proceed filtering when temperature is relatively low, so as to ensure that the normal operation of hydraulic system.
The utility model is rational in infrastructure, design is ingenious, efficiently solves existing oil absorption filter when environment temperature is relatively low
The problem of filtering cannot be proceeded, it is adaptable to hydraulic system.
