Background technique
Jack, which refers to, uses rigid top lift part as equipment, by the small stroke of top bracket or bottom claw
Open the light and small lifting equipment of weight.Jack is mainly used for the departments such as factories and miness, communications and transportation as Mechanical Help and other
The work such as weight, support.Its light structure is firm, flexibility and reliability, and a people can carry and operate.Jack, which is divided into, mechanical jack
Top and hydraulic jack etc., principle is had nothing in common with each other.In principle, the most basic principle that hydraulic drive is based on is exactly pa
Si Kadinglv, that is to say, that the pressure of liquid everywhere is consistent.In this way, in the system of balance, smaller piston upper
The pressure of application is smaller, and the pressure applied on big piston is also bigger, is able to maintain the static of liquid in this way.So logical
Cross the transmitting of liquid, different pressure on available difference ends, so that it may achieve the purpose that a transformation.People institute is common to be arrived
Hydraulic jack be exactly the transmitting that this principle is utilized to reach power.Back and forth to pull handle, pusher dog is on jin top under spiral
Push ratchet gap revolution, cone pinion drive large bevel gear, make weight lifting screw rod rotate, thus make jacking sleeve obtain raising or
Decline, and reach the function of lifting pulling force, but simple not as good as hydraulic jack.
But hydraulic jack is in use, due to hydraulic cylinder aging, in the biggish region of the temperature difference in use, being easy
Cracking, and hydraulic cylinder cracking leakage may be such that hydraulic thorough unloading, seriously threaten using safe.
