Repair of hydraulic jacks or as a tool to fill their own oil ?

Why do I need a jack?

All hydraulic fluid to operate the tools, including a hydraulic jack.He is single and dvuhplunzherny, and on the type of drive The designs - manual and electric.The main structural elements are the casing, retractable piston and hydraulic fluid.Due to the fact that oil is one of the main elements of the entire unit, the replacement of oil in the jack becomes common and necessary procedure.

main advantages of hydraulic jacks - rigidity, smooth running, stability, ability to lift large loads, precise braking, a high degree of efficiency.Thanks to the device, the lift can lift the load to a level equal to its base.This makes it more versatile than mechanical units.However, a more complicated system causes more problems with the repair when it is damaged.In this case, it is possible to pass or to a workshop for repair, or repair their own hands jack.

Note!If the repair is expected to produce in the workshop, it is worth to choose shops that specialize in this type of work.

Repair jacks: himself master

jack Damage can be caused by several factors.Firstly, possibly formed corrosion, which serves as stop for the shutter mechanism at the desired level in the structure.Secondly, the breakage can occur due to excessive loads, which led to the bending rod.Now we know the possible causes of exit mechanism of action, but the question arises, how to repair the jack?To do this, first of all, it is necessary to know how to parse it.Then just checked the state of corrosion and rod.

Jack is a cylinder within which the piston rod is moved by the hydraulic fluid.In his device a lot of carved stocks, base and enclosure.Disassembly and repair of its sequence is as follows:

• With key unscrewed all fasteners;
• bleed valve is extracted oil and the primary piston;
• doing a thorough inspection, check the quality of the gaskets and valve balls.If their condition is unsatisfactory, replace them with new ones;
• clears the mechanism of foreign elements and flushed the system;
• Immediately pour the new oil for hydraulic jacks;

Important!What kind of oil to pour into a jack for reliable operation?It is recommended to use a special oil for industrial equipment exclusively high-end .

• checked and, if necessary, change the old gum;
• After that, the unit can be assembled in reverse order.

Oil change once or twice

Despite the fact that the failure still occur, often have to change the oil for the jacks.Oil - is a necessary part of the design, which sets in motion the entire mechanism.Of course, for safe and correct operation of the fluid quality must always be good.How to pour the oil in the jack and that it needs?For work and new oil need for flushing liquid.No tools you do not need.Changing the oil is as follows:

• Slacken the filler tube and merges the old fluid;
• mechanism is cleaned with washing liquid.To complete this washing procedure is repeated several times;
• oil is poured into the tank to the maximum mark, stoppered, and made pumping system.Liquids with each pumping will become smaller, so it will be necessary to add.Priming is conducted as long as no bubbles appear, and the oil level does not become maximum.

Important!For complete pumping of the procedure should be repeated at least six times oil.

How do I change the oil in the jack correctly?This is done without any load on the gear.Use the machine for its intended purpose can be only after a complete fluid change.This procedure is carried out at least twice a year with a rare work.If the same mechanism is used more often, it must be replaced every month with a full washing system.
