油壓機（液壓機的一種）是一種通過專用液壓油做為工作介質，通過液壓泵作為動力源，靠泵的作用力使液壓油通過液壓管路進入油缸/活塞 ，然后油缸/活塞里有幾組互相配合的密封件，不同位置的密封都是不同的，但都起到密封的作用，使液壓油不能泄露。最后通過單向閥使液壓油在油箱循環使油缸/活塞循環做功從而完成一定機械動作來作為生產力的一種機械。
Hydraulic machine, hydraulicmachine, a) is a special hydraulic oil to do as the working medium, thehydraulic pump as a power source, by the force of the pump the hydraulic oilthrough hydraulic pipeline enters into the cylinder / piston and cylinder /piston has several groups cooperate each other seals, different set of sealsare different, but both the sealing effect, make the hydraulic oil can notleak. Finally through the one-way valve to hydraulic oil cylinder / piston inthe circulation work to complete a certain mechanical action as theproductivity of a mechanical circulation in the tank.
油壓機型號液壓油是按機器推薦的型號的，如果沒有推薦一般要看油壓機的壓力，如果壓力不算大的話用32即可。
Hydraulic www.kougasha.net model of hydraulicoil is recommended according to the model of the machine, if you do notrecommend the general need to look at the pressure of the hydraulic press, ifthe pressure is not large enough to use 32.
