YUKEN A3H series hydraulic pumps are high-pressure variable piston pumps developed by YUKEN Company. They have a variety of specifications and models. The following are introduced from four aspects: basic model, suffix combination, complete model example, and control type.：
Basic model
The basic models of YUKEN A3H series hydraulic pumps are named according to the displacement size. Common models include：
A3H16, A3H37, A3H56, A3H71, A3H100, A3H145, A3H180
The core specifications of YUKEN A3H100 series high pressure variable piston pumps are as follows：
1. Basic performance
Displacement: 100 ml/rev (fixed displacement)
Rated working pressure: 350 bar (35 MPa)
Maximum working pressure: 400 bar (40 MPa)
Speed range: 500-2000 rpm (normal working conditions), the maximum allowable intermittent speed is 2200 rpm
Driving power requirements: need to match the speed and pressure (for example, the theoretical power at 1000 rpm is about 183 kW)
2. Structure and control
Variable control method: support pressure compensation, load sensitivity and electro-hydraulic proportional control (model suffixes such as FR/LR correspond to different control types)
Installation form: flange installation (FR type is vertical pump shaft, LR type is side vertical)
Shaft extension specifications: Support S type (ANSI standard), A type (DIN 5480), etc., the maximum input torque is 1640-354500 N·m (depending on the shaft extension type)
Sealing material: Fluorine rubber piston ring, suitable for hydraulic oil/mineral oil medium
3. Examples of typical models
A3H100-FR01KK-10
Displacement: 100 ml/rev, rated pressure: 100 bar (variable adjustment)
Protection level: IP65, applicable temperature: -20℃ to +80℃
A3H100-LR09-55A4K-10
Rated pressure: 350 bar, maximum pressure: 400 bar
Drive configuration: 55 kW servo motor, cooling method: external cooling
Note: The specific selection needs to be combined with the system pressure, flow rate and control requirements, and the driving power needs to be calculated according to the actual working conditions.
