Once the hydraulic system leak

Hydraulic system leakage is a common hydraulic machines breakdown phenomenon, especially in the more serious crane parts hydraulic systems, mainly due to a pressure difference of the liquid flow in the hydraulic adapter fittings and the components and piping when there is a gap caused by the leak. In addition, poor working conditions will have a certain impact on the crane seal. Once the hydraulic system leak, the pressure will cause the system not be set up, hydraulic oil leak will cause environmental pollution, affecting the production and even have serious consequences incalculable. Here some of the impact of the project for a hydraulic system leak factors to simply talk about the leakage causes and countermeasures.

Hydraulic fittings in the assembly

Hydraulic fittings in the assembly should put an end to the brutal operation, if excessive force will make parts deformation, especially the use of copper and other beat the cylinder, sealing flanges and the like; parts before assembly to deal carefully examined, the assembly should be dipped in a little hydraulic adapter fittings oil, lightly pressed into use when cleaning diesel, especially seals, dust ring, O-ring and other rubber components, if gasoline is making it easy to aging lose their elasticity, thus losing the sealing performance.

Control processing quality hydraulic parts to prevent leakage from occurring

Control processing quality hydraulic fittings to prevent leakage from occurring.
(1) The difference between the cylinder hydraulic cylinder manufacturing quality, the new fuel tank leakage occurs, such as when machining the cylinder bore barrel (card keyway) chamfered keyway in card processing chamfers on both sides of the hole does not comply with the provisions of the drawings and greater than 20 °, when assembling the cylinder, first two holes on the piston seals caused by internal leakage cards injury, followed by the guide sleeve in the assembly, put the outer diameter of the O-ring seal fixed cut off one piece fitting or half ring, which gives the oil spill in the use of buried hidden dangers. When installed on a system device has some backpressure over a period of time the oil temperature reaches 50-60 ℃, it began to leak from the front cylinder.
(2) when the piston rod end chamfering, such as using the conventional 45 ° chamfer, guide sleeve mounted to the cylinder will make the O-ring card is broken. The use of 20 °, in the assembly will not be cut O-ring, which is the main measures to prevent leakage of hydraulic components.

Parher American Hydraulic Adapter widely used in engineering machinery

Parher american hydraulic adapter widely used in engineering machinery, agricultural machinery, hydraulic system control, mainly by controlling the opening and closing valves to control the flow of hydraulic fluid to the hydraulic machines direction control the mechanical action. The main sub-manual control, electrical control and pressure control and other types. Most of the domestic agricultural machinery is manual control and mechanical control distributor, imported a large majority of agricultural machinery and excavators for the electric control distributor. Automatic transmission lever is manually automobile distributor control valve.
