Yuken hydraulic power pack :

Hydraulic power pack :

Some power packs are large, stationary units and others are more portable. They have a hydraulic reservoir, which houses the fluid, regulators that allow users to control the amount of pressure the power pack delivers to a valve, pressure supply lines and relief lines, a pump and a motor to power the pump.A hydraulic power network is a system of interconnected pipes carrying pressurized liquid used to transmit mechanical power from a power source, like a pump, to hydraulic equipment like lifts or motors. The system is analogous to an electrical grid transmitting power from a generating station to end-users.

Hydraulic Power Unit Design and Operation. A hydraulic system employs enclosed fluid to transfer energy from one source to another, and subsequently create rotary motion, linear motion, or force. Hydraulic power units apply the pressure that drives motors, cylinders, and other complementary parts of a hydraulic system.

Uses of power pack :

A power pack or power pack is a part of a modular power train that contains some type of engine (most frequently an internal combustion engine but other types, including electric motors, are possible) and may also contain a transmission and various supporting components.

Power pack units :

Hydraulic Power Units are based on Pascal’s law of physics, drawing their power from ratios of area and pressure. Hydraulic Power Units are used in a wide range of applications, including: Machine Tools. Automation.

Work of hydraulic power pack :

The basic rule of using hydraulic power is Pascal’s Principle. Pascal’s Principle: pressure exerted on a fluid is distributed equally throughout the fluid. Hydraulics uses incomprehensible liquids so the applied pressure from one end (small arrow) is equal to the desired pressure on the other end (big arrow).

Yuken shaft

Shaft description :

A shaft is a rotating machine element, usually circular in cross section, which used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power. The various members such as pulleys and gears are mounted on it.

A shaft used for :

A drive shaft, driveshaft, driving shaft, propeller shaft (prop shaft), or Cardan shaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them.

There are two types of shaft: 

1.Transmission Shaft : 

Counter Shaft. The counter shaft lies parallel to the main shaft and is driven by the input shaft through a pinion gear. Output Shaft. The final component that carries the power out of the transmission gearbox and on to the wheels is the output shaft.

2.Machine Shaft :

 shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power. The various members such as pulleys and gears are mounted on it.

Air Blast Type Oil Cooler :

 General Information This valve is designed to use when a pump starts to bleed off the air which is enclosed in a suction line or another lines in the system.
When this valve is used to bleed off the air for pump start, connect inlet port of the valve adjacent as much as possible to the discharge port of the pump. For the purpose of removing the air in the line, install the air bleed valve at the highest point in the overall circuit. In either case, outlet port of the valve must be connected to the tank line and it should be extended under the oil level in the reservoir.

Hydraulic Fluids Type of Hydraulic Fluids Petroleum Base Oil :
Use R&O (Rust and Oxidation inhibitor) type oils or anti-ware type oils (equivalent to ISO VG-32 & 46). 

Synthetic Fluids:
Use Phosphate ester type fluids or polyol ester type fluids. Water Containing Fluids :
Use water glycol type fluids or water in oil emulsion type fluids. 
Other Special Fluids
Consult factory for information. “F5” Series Pipe Flange Kits This flange mounting surface measurements is based upon SAE 4 Bolt Spring Flange (Standard Pressure Series). 

Specifications Max:
 Operating Pressure Maximum operating pressure varies with the type of pipe connection or flange size. Refer to the applicable installation drawing.
