QPKY series hydraulic hoist mainly apply to opening and closing of the common plane
rapid gate in hydropower project, the basic parameters and the shape of
installation size is exactly the same as QPKY Ⅱseries, except the hydraulic
control valve using speed control one.

Hydraulic cylinder is the hydraulic energy into mechanical energy, reciprocating
motion to do (or swing movement) of the hydraulic actuators. It is simple,
reliable. Use it to achieve reciprocating movement can be removed from deceleration
devices, and no transmission gap, smooth motion, so in a variety of machines are
widely used in hydraulic systems. Hydraulic cylinder output force and the effective
area of the piston is proportional to the pressure difference on both sides;
hydraulic cylinder is basically a cylinder and cylinder head, piston and piston
rod, seals, cushioning device and the exhaust composition.
Buffer device and the exhaust depending on the specific application of the
occasion, other devices are indispensable.

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 opposite;
3. The air viscosity is small, the resistance to less than the hydraulic oil;
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.
