When talking about the characteristics and function of couplings used in Danfoss piston pumps, there are a few key points to consider: feature: Torque transmission: The main function of the coupling in a Danfoss piston pump is to transmit torque from the driving power source (such as an electric motor or engine) to the drive shaft of the pump. This enables the rotational motion of the power source to be transmitted to the pump, which drives the reciprocating motion of the plunger. Mechanical Link: The coupling provides the mechanical link between the power source and the pump. It usually consists of two halves or elements joined together to form a continuous connection. Couplings need to be securely fastened to ensure efficient torque transfer and prevent any slippage or misalignment during operation. Compatibility: Danfoss piston pump couplings are designed to be compatible with the specific pump models for which they are used. They are engineered to meet the size and operating requirements of the pump, ensuring proper installation and efficient power transmission. Materials of construction: Couplings used in Danfoss piston pumps are usually made of durable and high-strength materials to withstand the mechanical forces and stresses involved in pump operation. Common materials include steel, stainless steel or other alloys with excellent mechanical properties. Torsional stiffness: Couplings provide torsional stiffness, the ability to resist rotational deformation or twisting. This stiffness helps maintain accurate and synchronized motion between the power source and pump, ensuring proper timing and stroke length of the plunger. 90-L-100-KP-1-BB-60-L-3-F1-F-04-GBA-35-35-20 90L100KP1BB60L3F1F04GBA353520 90-L-100-KP-1-BB-60-R-3-F1-E-03-GBA-14-35-24 90L100KP1BB60R3F1E03GBA143524 90-L-100-KP-1-BB-60-S-3-F1-E-04-GBA-35-35-20 90L100KP1BB60S3F1E04GBA353520 90-L-100-KP-1-BB-80-L-3-F1-E-02-GBA-35-35-24 90L100KP1BB80L3F1E02GBA353524 90-L-100-KP-1-BB-80-L-3-S1-E-03-GBA-42-42-24 90L100KP1BB80L3S1E03GBA424224 90-L-100-KP-1-BB-80-L-3-S1-F-03-GBA-42-42-24 90L100KP1BB80L3S1F03GBA424224 90-L-100-KP-1-BB-80-P-3-F1-E-03-GBA-42-42-24 90L100KP1BB80P3F1E03GBA424224 90-L-100-KP-1-BB-80-P-3-S1-E-03-GBA-35-35-24 90L100KP1BB80P3S1E03GBA353524 90L100-KP-1-BB-80-P-3-S1-E-03-GBA-35-35-24 90L100KP1BB80P3S1E03GBA353524 90-L-100-KP-1-BB-80-P-4-S1-E-03-GBA-35-35-24 90L100KP1BB80P4S1E03GBA353524 Function: Power Transmission: Couplings enable the transmission of power from the drive power source to the piston pump. It ensures that the rotational motion of the power source is efficiently converted to the reciprocating motion required by the plunger to generate hydraulic pressure. Misalignment Compensation: In some cases, the power supply and pump may not be perfectly aligned due to installation tolerances or system vibrations. Couplings help compensate for slight misalignments between the drive and driven shafts, allowing smooth and efficient power transmission without undue stress on the pump or power source. Shock Absorption: During operation, a plunger pump may experience sudden changes in load or pressure, causing shock or vibration. Couplings help absorb these shocks and vibrations, protecting the pump and its components from excessive wear or damage. Flexibility and resilience: Couplings used in Danfoss piston pumps have a degree of flexibility to accommodate small angular, axial or parallel misalignments between the power source and the pump. This flexibility helps protect pumps and other connected components from excessive stress or strain. Maintenance and serviceability: Couplings in Danfoss piston pumps should be designed for ease of maintenance and serviceability. It should allow easy disassembly and reassembly when parts need to be inspected, lubricated or replaced. This ensures that maintenance tasks can be carried out efficiently, minimizing downtime. Alignment Accuracy: Couplings play a vital role in maintaining proper alignment between the drive power supply and the pump. Proper alignment helps optimize power transmission efficiency and reduces the risk of premature wear or failure of couplings or other connected components. Proper alignment is achieved through precise coupling design and installation procedures. Coupling types: Danfoss piston pumps are available with different types of couplings depending on the specific application and requirements. Common types of couplings include jaw couplings, gear couplings, disc couplings or elastic couplings. Each type has its own advantages in terms of torque transfer, misalignment compensation, flexibility and damping characteristics. 90-L-100-KP-1-BB-80-R-3-F1-F-00-GBA-29-29-24 90L100KP1BB80R3F1F00GBA292924 90-L-100-KP-1-BB-80-R-3-S1-E-03-GBA-42-42-24 90L100KP1BB80R3S1E03GBA424224 90-L-100-KP-1-BC-60-L-3-F1-E-02-GBA-38-38-24 90L100KP1BC60L3F1E02GBA383824 90-L-100-KP-1-BC-60-L-3-F1-E-03-GBA-38-38-24 90L100KP1BC60L3F1E03GBA383824 90-L-100-KP-1-BC-60-L-3-F1-F-03-GBA-38-38-24 90L100KP1BC60L3F1F03GBA383824 90-L-100-KP-1-BC-60-L-4-F1-E-03-GBA-35-35-24 90L100KP1BC60L4F1E03GBA353524 90-L-100-KP-1-BC-60-P-3-F1-F-03-GBA-35-35-24 90L100KP1BC60P3F1F03GBA353524 90-L-100-KP-1-BC-60-P-3-F1-F-03-GBA-38-38-24 90L100KP1BC60P3F1F03GBA383824 90-L-100-KP-1-BC-60-P-4-S1-E-03-GBA-35-35-24 90L100KP1BC60P4S1E03GBA353524 90-L-100-KP-1-BC-60-R-3-F1-E-03-GBA-38-38-24 90L100KP1BC60R3F1E03GBA383824 Damping and resonance control: Couplings in Danfoss piston pumps may incorporate damping features to minimize vibration and resonance transmission between the power supply and the pump. Damping helps reduce noise levels and protects the pump and its components from excessive vibration, ensuring smooth and reliable operation.
