Electric Mechanical Stainless Hydraulic Cylinder Single Acting Flat
QPPY-D type hydraulic hoist is also used for general flat gate to
work for opening and closing. Working requirements are similar to
QPPYII type, but its installation forms are different from QPPYII
type. The remarkable difference is to reduce half space height in
order to make more reasonable decorate. The acceptable working
temperature should around from -35℃-50℃.
QPPY-D series hydraulic hoist : Flat gate hydraulic hoist, flat
gate with hang upside down.
Cylinder and cylinder of the advantages and disadvantages:
1. As the pneumatic system uses pressure is generally in the range
of 0.2-1.0Mpa, so the cylinder is the driving force can not do
high-power components. Hydraulic cylinders can be done relatively
large power device, use the hydraulic system;
2. From the media about the air can be unlimited, no cost and
supply difficulties, the gas will be used directly into the
atmosphere, convenient, no pollution, hydraulic oil is the
3. The air viscosity is small, the resistance to less than the
4. But the air is much larger than the compression rate of
hydraulic oil, so it's working smoothly and to respond to far
backward in this regard.
Hydraulic cylinder hydraulic system is the most important
components of implementation, it can convert mechanical energy of
hydraulic and matched with a variety of transmission to complete
all of the mechanical movement. Hydraulic cylinder has a simple
structure, the output force, stable and reliable performance and
easy maintenance, wide range of applications and so on.
