Customized Welded Hydraulic Cylinders Double Acting Hydraulic Ram
QPPY series hydraulic hoist
Flat gate hydraulic hoist
QPPY series flat gate hydraulic hoist, the basic parameters have
been approved as a ministerial-level by the Ministry of Water
Resources and Hydropower of People's Republic of China, serial
number is SD113-83, it is executed all over the country since
January 1, 1984.
This series of hydraulic hoist can mainly be used for the opening
and closing of common flat gate in water Resources and hydropower
projects, with the characteristics of advanced technology,
reasonable process, compact structure, economical, safe and
reliable, and convenient maintenance.
QPPY series hydraulic hoist : Flat gate hydraulic hoist
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.
