The oil discharge port of the plunger pump should not be directly connected to the oil inlet port. The discharge port of the plunger pump is designed to connect to a low pressure return line or reservoir to allow excess hydraulic oil to flow back into the system. Connecting the drain port to the oil inlet port will create a direct path for the oil to flow back to the pump, bypassing the normal hydraulic circuit. This disrupts the proper operation of the pump and causes problems such as cavitation, elevated temperatures and reduced pump performance. It is important to follow the manufacturer's instructions and guidelines for proper connection and connection of the displacement and inlet ports of the displacement pump. When connecting a piston pump, it is important to ensure proper plumbing to maintain the integrity and functionality of the hydraulic system. The following are some key considerations when connecting the discharge and inlet ports of a displacement pump: Drain port: The discharge port of the plunger pump should be connected to the low pressure return line or liquid reservoir. This allows excess hydraulic fluid and any contaminants or air to return to the tank for proper filtration and cooling before being recirculated through the system. Oil Inlet: The oil inlet of the piston pump should be connected to a suitable hydraulic oil supply line or reservoir. This ensures a constant supply of hydraulic oil to the pump for proper operation. Separate paths: It is critical to maintain separate paths for drain and inlet ports. Connecting them directly will result in oil contamination, pressure loss and potential damage to the pump. Plumbing Assemblies: When connecting discharge and inlet ports, use appropriate hydraulic fittings, hoses, and connectors that are compatible with system pressure and flow requirements. Ensure proper sealing and secure connections to prevent leakage or pressure drop. Follow Manufacturer's Guidelines: Always refer to the manufacturer's documentation, installation instructions, and guidelines for the specific displacement pump model being used. These guidelines provide specific recommendations for piping connections, including drains and inlets. 90L100-KN-1-NN-80-S-4-S1-E-03-GBA-38-38-24 90L100KN1NN80S4S1E03GBA383824 90-L-100-KN-1-NN-80-S-4-S1-E-03-GBA-38-38-24 90L100KN1NN80S4S1E03GBA383824 90-L-100-KN-5-AB-80-R-4-S1-F-03-GBA-32-32-24 90L100KN5AB80R4S1F03GBA323224 90-L-100-KN-5-AB-80-S-4-C7-E-03-GBA-20-20-24 90L100KN5AB80S4C7E03GBA202024 90-L-100-KN-5-AB-80-S-4-S1-F-03-GBA-32-32-24 90L100KN5AB80S4S1F03GBA323224 90-L-100-KN-5-BC-80-D-4-F1-L-03-GBA-35-35-24 90L100KN5BC80D4F1L03GBA353524 90-L-100-KN-5-CD-60-D-4-F1-L-03-GBA-35-35-28 90L100KN5CD60D4F1L03GBA353528 90-L-100-KN-5-CD-80-D-4-F1-L-03-GBA-35-35-28 90L100KN5CD80D4F1L03GBA353528 90-L-100-KN-5-CD-80-R-3-C7-E-03-EBC-38-38-24 90L100KN5CD80R3C7E03EBC383824 90-L-100-KN-5-CD-80-R-3-C7-E-04-GBA-32-32-24 90L100KN5CD80R3C7E04GBA323224 By following these precautions and manufacturer's guidelines, you can ensure proper piping to the discharge and inlet ports of your piston pump, which promotes efficient operation, life, and reliability of your hydraulic system. Pressure Control: Connecting the discharge port to the inlet port will defeat the pressure control of the piston pump. The discharge port is designed to handle low pressure return flow, while the inlet port is responsible for supplying pressurized fluid to the pump. Connecting them together can cause pressure fluctuations and instability in the hydraulic system. Risk of cavitation: Connecting the drain to the inlet increases the risk of cavitation. Cavitation occurs when the pressure drops too low, causing air bubbles to form in the hydraulic fluid. This can damage the pump and other components of the system. Proper separation of discharge and inlet ports helps prevent cavitation by maintaining the necessary pressure levels. Pump Efficiency: Maintaining a proper connection between the discharge port and the oil inlet port ensures that the displacement pump operates at its design efficiency. Connecting them together disrupts the flow dynamics and compromises the overall performance of the pump. System Stability: Separating the drain and inlet ports improves overall system stability. It allows other components to function properly, such as pressure relief valves and filtration systems, which depend on a proper fluid path between the pump and reservoir. Safety Precautions: Connecting a drain to an inlet may result in potential safety hazards such as elevated pressure levels or uncontrolled fluid flow. It is important to adhere to proper plumbing practices to ensure the safe and reliable operation of hydraulic systems. In short, the oil discharge port and the oil inlet port of the plunger pump must be connected separately. Connecting them together can lead to various problems including pressure fluctuations, cavitation, reduced pump efficiency and compromised system stability. Always follow manufacturer guidelines and best practices to ensure proper piping of the displacement pump and maintain the integrity of the hydraulic system. certainly! Regarding the connection of the oil discharge port and the oil inlet port of the plunger pump, there are several points to be noted: Filtration and Contamination Control: Proper separation of drain and inlet ports allows for effective filtration of hydraulic oil. The drain is usually connected to a reservoir or a dedicated return line equipped with a filter to remove contaminants and maintain fluid cleanliness. Connecting it to the oil inlet bypasses the filtration system, increasing the risk of contamination and potential damage to the pump and other system components. System Diagnostics: Keeping the drain ports separate allows for easy monitoring and diagnostics of the hydraulic system. By analyzing the fluid returning through the vent, problems such as excessive wear, contamination, or abnormal fluid properties can be identified. This information helps in diagnosing and resolving potential problems before they cause significant damage or system failure. 90L100-KN-5-CD-80-R-3-S1-E-03-GBA-38-38-24 90L100KN5CD80R3S1E03GBA383824 90-L-100-KN-5-CD-80-R-3-S1-E-03-GBA-38-38-24 90L100KN5CD80R3S1E03GBA383824 90-L-100-KN-5-CD-80-R-4-F1-F-03-GBA-32-32-24 90L100KN5CD80R4F1F03GBA323224 90-L-100-KN-5-CD-80-R-4-S1-E-03-GBA-42-42-24 90L100KN5CD80R4S1E03GBA424224 90L100-KN-5-CD-80-S-3-C7-E-03-GBA-30-30-24 90L100KN5CD80S3C7E03GBA303024 90L100-KN-5-CD-80-S-3-C7-E-03-GBA-32-32-24 90L100KN5CD80S3C7E03GBA323224 90L100-KN-5-CD-80-S-3-C7-E-03-GBA-36-36-24 90L100KN5CD80S3C7E03GBA363624 90-L-100-KN-5-CD-80-S-3-C7-E-03-GBA-36-36-24 90L100KN5CD80S3C7E03GBA363624 90-L-100-KN-5-CD-80-S-4-F1-F-03-GBA-32-32-24 90L100KN5CD80S4F1F03GBA323224 90L100-KN-5-NN-60-S-3-C7-E-03-GBA-36-36-24 90L100KN5NN60S3C7E03GBA363624 Maintenance and Serviceability: Separate connections for maintenance drain and oil inlet simplify maintenance and repair tasks. It allows easy access to the drain for fluid changes, filter changes or inspections. Likewise, servicing the oil inlet is made simpler without disturbance from the discharge flow. Compliance with standards: Following proper plumbing practices ensures compliance with industry standards and regulations. Many hydraulic system design standards require that the drain and inlet ports be separated to maintain the overall integrity, reliability and safety of the system. Manufacturer's Warranty: Connecting the drain and inlet together may void the manufacturer's warranty. Manufacturers often provide guidelines and specifications for proper piping for their pumps, and any deviation from these recommendations may result in warranty issues. It is essential to refer to the manufacturer's documentation and guidelines specific to the model of Danfoss piston pump being used. Following these guidelines will help maintain the performance, reliability and life of your hydraulic system while minimizing potential problems associated with incorrect connections.
