Cautions on Piping and Assembling
A hydraulic unit may incorporate steel pipes, stainless pipes, or hoses. Nominal size of pipes: A (millimeter) and B (inch), outer diameter is same. Scale A (millimeter) is usually applied to pipes for flareless fittings. Schedule: it refers to wall … Continue reading
Manifold
Manifolds connect ports of hydraulic components with drilled metal blocks, instead of piping. They usually have outlet ports with tapered threads (Rc) or connection flanges. Manifolds have the following advantages. i . They can reduce leakage and vibrations with simple … Continue reading
Selection of Reservoir Capacity
(1) Selection Based on Pump Output Capacity Generally, reservoir capacity should be three to five times larger than the pump output capacity. In a closed circuit, the reservoir capacity can be about 50 percent of the pump output capacity. (2) … Continue reading
Requirements for Hydraulic Reservoirs
(1) A reservoir should be set up with a method to shut out foreign substances such as dust. Example: Filter at a ventilation or a filling port. (2) A reservoir should be set up so that its components can be … Continue reading
Fittings
Screw, flange, welded, flare, and flareless fittings are available for line connection and equipment setup. In addition, the following fittings are among the available selection. (1) Socket: Connects lines into straight configurations. Fittings that connect lines with different bores are … Continue reading
Rotary Joints
This joint transmits working fluids to rotary parts. The rotary and swivel types are available.
Self-Sealing Couplings
This coupling allows connection/disconnection of rubber hoses with one-touch operation.
Rubber (plastic) Hoses
Rubber hoses are used when metal-tube connection is not allowed, some moving parts are present, and vibration protection is required. The hose consists of an inner layer, a reinforcement layer, and an outer layer, and couplings are connected to each … Continue reading
Shaft Couplings (Couplings)
These couplings connect a pump shaft and a prime mover. With due consideration to axial misalignment of shafts in hydraulic equipment, the following couplings are available. (1) Flange-type flexible-shaft coupling: with two flanges, this coupling uses the properties of rubber … Continue reading
Automatic Water Supply Valve with a Temperature Detector
The valve automatically opens to supply cooling water and decrease the temperature when a temperature detector placed in a reservoir detects that the working fluid temperature reaches a certain level. Depending on the detected temperature, the valve can adjust the … Continue reading
