The design of the plunger pump cylinder plunger is an important aspect of the construction of the plunger pump. The following introduces some basic knowledge points of plunger pump cylinder plunger design: 1. Materials: Cylinder plungers are usually made of high-strength materials that can withstand the high pressures and forces involved in hydraulic pump applications. Common materials used for cylinder plungers include hardened steel, stainless steel or other alloys with excellent mechanical properties. 2. Plunger Diameter: The diameter of the cylinder plunger plays a vital role in determining the flow and pressure capabilities of the pump. Larger diameter plungers generally provide higher flow rates but lower pressures, while smaller diameter plungers provide higher pressure output at lower flow rates. The plunger diameter is carefully selected according to specific application requirements. 3. Plunger length: The length of the cylinder plunger depends on the stroke length required for the pump to operate. Stroke length is the distance the plunger travels back and forth within the cylinder during each pumping cycle. A longer plunger accommodates a longer stroke length, which affects pump displacement and overall performance. 4. Plunger Surface Finish: The surface finish of the cylinder plunger is critical for proper sealing and minimizing friction between the plunger and the cylinder wall. Typically, plunger surfaces are precision ground or honed for a smooth, consistent finish. A high-quality surface finish helps reduce wear, improve sealing efficiency and extend plunger life. 90-R-130-KA-1-NN-80-L-4-F1-H-00-GBA-38-14-24 90R130KA1NN80L4F1H00GBA381424 90-R-130-KA-1-NN-80-L-4-F1-F-03-GBA-20-20-24 90R130KA1NN80L4F1F03GBA202024 90-R-130-KA-1-NN-80-L-3-F1-H-03-GBA-42-42-24 90R130KA1NN80L3F1H03GBA424224 90R130-KA-1-NN-80-L-3-F1-H-03-GBA-42-42-24 90R130KA1NN80L3F1H03GBA424224 90-R-130-KA-1-NN-80-L-3-F1-H-03-GBA-38-38-20 90R130KA1NN80L3F1H03GBA383820 90R130-KA-1-NN-80-L-3-F1-H-03-GBA-38-38-20 90R130KA1NN80L3F1H03GBA383820 90-R-130-KA-1-NN-80-L-3-F1-H-03-GBA-35-35-24 90R130KA1NN80L3F1H03GBA353524 90R130-KA-1-NN-80-L-3-F1-H-03-GBA-35-35-24 90R130KA1NN80L3F1H03GBA353524 90-R-130-KA-1-NN-80-L-3-F1-F-03-GBA-42-42-24 90R130KA1NN80L3F1F03GBA424224 90R130-KA-1-NN-80-L-3-F1-F-03-GBA-42-42-24 90R130KA1NN80L3F1F03GBA424224 5. Sealing mechanism: The cylinder plunger needs to be effectively sealed to prevent hydraulic oil leakage. Depending on the specific pump design, various sealing mechanisms may be used. Common seal types used in plunger pump plungers include O-rings, V-ring seals, or specially designed lip seals. The choice of sealing mechanism depends on factors such as pressure requirements, operating conditions, and compatibility with hydraulic oil. 6. Plunger Coating: In some applications, cylinder plungers can be coated with special materials to improve their performance and durability. For example, the surface of the plunger can be plated with hard chromium to improve wear resistance, corrosion resistance and wear resistance. Other coatings, such as ceramic or PTFE-based coatings, can also be used to improve sealing efficiency and reduce friction. 7. Precision and Tolerance: The manufacture of cylinder plungers requires high precision and tight tolerances to ensure smooth operation and optimum pump performance. Close attention is paid to dimensional accuracy, concentricity and surface finish during manufacturing to maintain required specifications. 8. Plunger shape: The shape of the cylinder plunger can vary according to the design and application requirements of the pump. Common shapes include cylindrical, stepped or tapered designs. The shape of the plunger affects the flow characteristics, pressure distribution and sealing efficiency within the cylinder. 9. Ports and passages: The cylinder plunger may have ports or passages that allow hydraulic fluid to flow into and out of the pump chamber. These ports and channels are carefully designed to control the direction and timing of fluid flow during the pumping cycle, ensuring proper operation and fluid distribution within the pump. 10. Plunger grooves: In some plunger pump designs, the cylinder plunger may have grooves or notches along its length. These grooves accommodate the placement of piston rings or other sealing elements that provide enhanced sealing performance and reduce internal leakage between the plunger and cylinder wall. 11. Plunger bearings and guide rails: To ensure smooth and precise movement of the cylinder plunger within the pump cylinder, bearings or guide rails can be incorporated into the design. These components reduce friction, minimize wear and provide stability during the reciprocating motion of the plunger. 12. Anti-rotation mechanism: In some plunger pump designs, an anti-rotation mechanism may be employed to prevent the plunger from rotating during operation. This is important to maintain proper alignment of the sealing elements and ensure consistent and effective sealing performance. 13. Pressure balancing feature: Some plunger pump designs incorporate a pressure balancing feature within the cylinder plunger. These characteristics help balance the pressure on both sides of the plunger, reducing the axial force acting on it. This helps to increase the overall efficiency and life of the pump by minimizing wear and reducing loads on supporting components. 90-R-130-KA-1-NN-80-L-3-F1-F-03-GBA-26-26-24 90R130KA1NN80L3F1F03GBA262624 90-R-130-KA-1-NN-80-L-3-F1-F-03-GBA-23-23-24 90R130KA1NN80L3F1F03GBA232324 90-R-130-KA-1-NN-80-L-3-F1-F-00-GBA-23-23-28 90R130KA1NN80L3F1F00GBA232328 90R130-KA-1-NN-80-L-3-F1-F-00-GBA-23-23-28 90R130KA1NN80L3F1F00GBA232328 90-R-130-KA-1-NN-80-L-3-F1-F-00-GBA-17-17-20 90R130KA1NN80L3F1F00GBA171720 90R130-KA-1-NN-80-L-3-F1-F-00-GBA-17-17-20 90R130KA1NN80L3F1F00GBA171720 90-R-130-KA-1-DE-80-R-3-F1-H-09-GBA-38-38-24 90R130KA1DE80R3F1H09GBA383824 90R130-KA-1-DE-80-R-3-F1-H-09-GBA-38-38-24 90R130KA1DE80R3F1H09GBA383824 90-R-130-KA-1-DE-80-R-3-F1-F-03-GBA-38-38-24 90R130KA1DE80R3F1F03GBA383824 90-R-130-KA-1-DE-80-R-3-C8-F-04-GBA-32-32-20 90R130KA1DE80R3C8F04GBA323220 14. Anti-Backflow: To prevent backflow of hydraulic oil when the plunger changes direction, the cylinder plunger design may include a check valve or other mechanism. These prevent backflow and maintain the directionality of fluid movement, ensuring proper pump operation. 15. Corrosion and pollution resistance: Depending on the application environment and the type of hydraulic oil used, the cylinder plunger may be additionally treated or coated to enhance its resistance to corrosion, pollution or chemical attack. This helps maintain plunger integrity and performance under harsh operating conditions. The design of the cylinder plunger in a plunger pump involves various engineering considerations such as hydraulic performance, sealing efficiency, wear resistance, and compatibility with the operating environment. Together, these design elements contribute to the reliable and efficient operation of the piston pump.
