Due to more air in the hydraulic cylinder operation, new or long time placed electric jacks are likely to appear small jump. High pressure large tonnage remote control jack can repeat movement 2-3 times, clear the air in the cavity. Remote server is to use edible oil as material, be sure to do a good job in the maintenance of oil and the machine, to prevent blocking or oil seepage, harm the actual effect. The actual operation should strictly implement the technical standards, customers should check and maintain regularly according to the application status.

New or long-term electric jack, because the hydraulic cylinder running air more, gradually applied, hydraulic cylinder may appear small jump, can be high pressure large ton remote control jack full load repetitive movement, remove the air in the chamber, long-term idle electric jack, because the hydraulic seal does not work for a long time, resulting in the hydraulic seal hardbottom. 87.5mpa(875kgf/cm2) hydrostatic test should be carried out during the inspection. Such as engineering blasting, protruding, water leakage, etc., can not be used. In actual operation, technical standards should be strictly implemented, and customers should check and maintain them regularly according to the application situation.

Hydraulic jack with the car is just the support point of basic tire replacement or suspension inspection, can not replace the car lift to carry out large repair work, it is prohibited to put the human body or arm under the car body, to prevent risks. In addition, after the jack is completely lifted, the spare tire or unloaded tire can be put under the car body to do a temporary commercial insurance, even if the hydraulic jack problem will not lead to greater damage. The basic concept of the jack, the top of the liquid pressure in each place is the same, in the balance of force, the pressure on the small cylinder is relatively small, the pressure of the large hydraulic system is relative, it is caused by the transmission of the liquid, can make the pressure is different, to ensure a change of purpose.

When applying the jack, special attention should be paid to checking whether each part of the jack is normal. And the application should be careful to follow the requirements of the main parameters. It can not be heavy, or it can cause the liquid in the hydraulic cylinder to reveal under the strong pressure effect. There's a lot of risk. If the liquid in the pump of the hydraulic jack manufacturer is not enough, it should immediately fill the car oil after overconsideration, so that the jack can be used normally.
