Hydraulic jacks are made of edible oil. Be sure to do a good job in the maintenance of oil and the machine to prevent blockage or oil seepage and harm the actual effect. For some new words, the hydraulic jack for a long time, due to the hydraulic cylinder operation in the gas more, in the application, the hydraulic cylinder is likely to appear a small jump phenomenon, hydraulic jack is full of reciprocating motion 2-3 times, to remove the gas in the chamber.

And pay attention to the hydraulic jack high pressure tubing in production must be through 105Mpa experiment, but because the rubber hose is very easy to aging, so the customer must often complete the inspection, generally for six months, often used for three months, inspection to 87.5mpa water pressure test, if there is engineering blasting, protrtion, Leakage and other phenomena can not be applied.

Long-term vacant hydraulic jack, because the hydraulic seal does not work for a long time, resulting in hydraulic seal hardbase, endangering the service life of the hydraulic jack, so the hydraulic jack is not needed, 2-3 times a month, the actual operation of the hydraulic jack strictly implement the technical standards, customers should according to the application of regular maintenance.

In the application of hydraulic jack if the phenomenon of air play, you can release the oil screw on the pressure pump body, the pump body vertical head down the air play two times, then tighten the oil screw, you can be applied again. When using, do not add wheel weight or overweight, in order to prevent the risk of hydraulic jack damage. Do not remove the quick connector under load to prevent safety accidents and damage to parts.

Jack manufacturers to deal with a variety of situations of hydraulic dry catkins how to view
