In application areas as diverse as industrial, mobile, marine, machine tools, agricultural equipment and offshore installations, machinery that needs to generate high forces in a compact package will typically rely on hydraulic drive systems.
At the heart of that power transmission system is the hydraulic pump, in turn driven by a prime mover which might be a motor electric, hydraulic, pneumatic or an I.C.E.
Q: Why is coupling hydraulic pumps to prime movers critical for machinery performance?
A: Proper coupling ensures precise shaft alignment, improves efficiency, reduces wear, and prevents premature pump failure. It also minimizes maintenance costs and extends the system’s lifespan by reducing unnecessary stress on components like seals and bearings.
Q: What role does a hydraulic pump play in machinery systems?
A: Hydraulic pumps are at the heart of power transmission systems in applications like industrial, mobile, marine, agricultural, and machine tools. They deliver high force in compact packages, powered by a prime mover, which can be electric, hydraulic, air motor, or internal combustion engine.
Q: What happens if hydraulic pumps are improperly installed?
A: Improper installation can lead to pump failure, increased maintenance costs, and reduced productivity. Additionally, misaligned pump shafts can cause excessive wear on seals and bearings, shortening the system’s lifespan.
Q: What are torsional resonant frequencies, and why do they matter?
A: Torsional resonant frequencies are vibrations that can develop within the drivetrain. If unaddressed, they can damage components, reduce system life, and impact performance.
Q: How does jbj Techniques ensure proper coupling for hydraulic systems?
A: jbj Techniques designs, manufactures, and integrates customized components, including hydraulic pump adapters, bellhousings, and couplings. Their tailored solutions ensure precise coupling, optimized performance, and reduced wear for various machinery systems.
Q: What are jbj Techniques’ hydraulic adapters, and how are they customized?
A: Hydraulic adapters consist of bellhousings and flexible drive couplings, fully machined to match driving and driven components. They can handle shaft-to-shaft, flange-to-shaft, or flange-to-flange connections and are tailored for specific system requirements.
Q: What electric motor sizes and configurations are supported by jbj bellhousings?
A: jbj bellhousings accommodate IEC frame sizes from D56 to D400 (0.06–750 kW) and are compatible with B5 or B14 flange configurations. They also support NEMA and imperial frame motors with C-face or D- flange fitments.
Q: What materials are available for jbj bellhousings?
A: Standard options include aluminum and cast iron, with exotic materials available upon request. Aluminum bellhousings come in monoblock or composite formats for flexibility and rapid delivery—often same or next day.
Q: What coupling options does jbj offer?
