Abstract
The utility model relates to a high-pressure oil way magnetic filter for a hydraulic system of an excavating machine. The high-pressure oil way magnetic filter comprises a cylinder, wherein one end of the cylinder is closed, the closed end of the cylinder is provided with a pipe joint, the other end of the cylinder is provided with a closed screwing cap, the screwing cap is provided with the pipe joint, the cylinder is internally provided with a magnet support, a magnetic ring is inlaid on an outer ring of the magnet support, and a filter net and an oil filtering disc are arranged at the end part of the magnet support in the cylinder. The high-pressure oil way magnetic filter provided by the utility model is simple in structure and convenient to manufacture and mount, and can be widely applied; the high-pressure oil way magnetic filter is safe and reliable, small in practical volume and light in weight; the labour intensity of operating personnel can be lightened, the maintenance time is reduced, the efficiency is high, and the operation is convenient; and about 85% of scrap iron in an oil way can be filtered, so that the service life of a rolling-over cylinder is prolonged, the pollution of hydraulic oil is reduced, the work quality is greatly improved, and the strength in a maintenance process is reduced.
Description
Technical field:
The utility model belongs to the hydraulic machinery oil circuit filter device, particularly a kind of excavator hydraulic system high-pressure oil passage magnetic filter.
Background technique:
Excavator is the visual plant of harbour handling operation, bulk goods operation within being usually used in cabin.Because manufacturing operation is busy, capacity utilization is higher, and the operation dust is large in the cabin, and operating environment is abominable.The dust that flies upward has had a strong impact on driver's sight line, and narrow and small underdeck operation space often is collided excavator.The most easy to wear is excavator bucket oil cylinder, the iron filings that produce after the wearing and tearing can produce the proper flow that hinders hydraulic oil in the middle of certain valve body that destroys or rest in the system to other hydraulic element by flowing of hydraulic oil, the normal pressure of upset system causes the fault of other elements in the system.
Therefore need to maintain rapidly excavator after every subjob, remove iron filings, assurance equipment normally uses.But the cleaning of the iron filings in the excavator hydraulic system is to bother very much with consuming time.In order to shorten service time, improve operating efficiency, the spy has developed this device.This device is installed in the bucket cylinder oil circuit of excavator, is used for absorbing and filtering the iron filings of generation.
The model utility content
The purpose of this utility model provides a kind of excavator hydraulic system high-pressure oil passage magnetic filter.Reach the labor intensity that can alleviate the operating personnel, reduce service time, efficient is high, convenient working.
Content of the present utility model is:
A kind of excavator hydraulic system high-pressure oil passage magnetic filter, it is characterized in that: a cylinder, the sealing of cylinder one end, at closed end pipe joint is arranged, the cylinder the other end has the sealing spiral cover, and pipe joint is arranged on the spiral cover, and magnet holder is arranged in cylinder, stud with magnet ring in the magnet holder outer ring, in the end of cylinder internal magnet support filter screen and oil filtering disc are housed.
Characteristic advantage of the present utility model:
After magnetic filter is installed, the trickle metal granule that produces will be adsorbed by magnetic filter, the metal granule that produces does not cause wearing and tearing or obstruction in the middle of just can not entering oil cylinder and system, namely prolonged the working life of overturning oil cylinder, reduced again the pollution of hydraulic oil, greatly improve workmanship, reduced the intensity in the maintenance process.
The advantage of excavator hydraulic system high-pressure oil passage magnetic filter: simple in structure, be convenient to make, easy for installation, applied range.Safe and reliable, practical volume is little, and is lightweight.Can alleviate operating personnel's labor intensity, reduce service time, efficient is high, convenient working.Iron dust filtration in the oil circuit can be fallen about 85%.
Description of drawings
Fig. 1 is excavator hydraulic system high-pressure oil passage magnetic filter overall diagram.
Fig. 2 is excavator hydraulic system high-pressure oil passage magnetic filter magnet holder figure.
Fig. 3 is excavator hydraulic system high-pressure oil passage magnetic filter filter screen figure.
Fig. 4 is excavator hydraulic system high-pressure oil passage magnetic filter oil filtering disc figure.
Among the figure: 1 cylinder, 2 pipe joints, 3 spiral covers, 4 magnet holder, 5 magnet rings, 6 filter screens, 7 oil filtering discs.
Embodiment
A kind of excavator hydraulic system high-pressure oil passage magnetic filter as shown in the figure, a cylinder, the sealing of cylinder one end, at closed end pipe joint is arranged, the cylinder the other end has the sealing spiral cover, and pipe joint is arranged on the spiral cover, in cylinder interior magnet holder is housed, stud with magnet ring in the magnet holder outer ring, filter screen and oil filtering disc are equipped with in the end of the magnet holder in cylinder.
The special-purpose oil filter of excavator be a steel, hollow, that have certain mechanical strength, in the closed circular tubular of filter element is housed.Cylinder one side is detachable.In the both sides of cylinder axial location boring and be welded with pipe joint, this joint connects with excavator bucket oil cylinder turnover oil pipe respectively.
The technical characterstic of this device: 1) filter screen, oil filtering disc, magnet, magnet holder etc. are housed respectively in cylinder.2) fluid of turnover oil cylinder is worked through just entering in the oil cylinder after filtering respectively.3) the magnet filtrating equipment can fall the iron dust filtration in the fluid about 85%.Using method, effect
Using method: the appropriate location is respectively installed one in bucket cylinder import oil circuit, outlet oil circuit.And take effective ways to be fixed.
