Double Acting Central Solid Hydraulic Jack Hollow Plunger Hydraulic
Cylinders
Description of double acting jack
Our company's double-acting Jack (double-acting jack), especially
in large-scale projects, is easy to operate and control hydraulic
jack, designed a safe pressure retaining device, built-in pressure
relief valve to prevent overload, to protect the jack for safe
operation. The connection of the device is made of high-pressure
rubber pipe and threaded joint. The utility model has the
advantages of fast operation and overcomes the shortcomings of oil
leakage of fast traditional joints. It is mainly used for
installation, lifting and disassembly of equipment in electric
power, construction, machinery manufacturing, mining, railway
bridges, shipbuilding and other industries.
Product characteristics
Outer ring threads, plunger threads and base holes are easy to
install (for most models)
The piston part and the inside of the guide cap are welded with
copper. The surface of the piston rod is plated with hard chromium,
and the cylinder is never pulled. The piston rod has strong wear
resistance.
Baking paint surface makes corrosion resistance stronger
Movable saddle to protect plunger in operation
Internal safety valve to prevent accidental overload
Fast connectors are used in all models.
Dust-proof ring reduces pollution and prolongs service life of
hydraulic cylinder
Usage method
If the oil quantity of the pump body is insufficient, the working
oil must be added to the pump before it can work.
Estimate lifting weight, avoid overloading
To determine the center of gravity of the lifting object and to
select the focus of the jack, it is necessary to consider whether
the hardness of the ground is cushioned with tough wood, so as to
avoid the danger of dumping when lifting.
When jacks lift heavy objects, they should be supported firmly by
tough timber in time. It is forbidden to use jacks as supports so
as to avoid unbalanced loads and the danger of dumping.
When in use, the quick joint of the manual pump is docked with the
top, then the position is selected, and the drain screw on the oil
pump is tightened to work. Loosen the discharging screw and unload
the cylinder
