The hydraulic priming feature of the plunger pump is designed to facilitate smooth and controlled pump priming, which is the process of filling the pump chamber with liquid to remove any air or gas and create a proper fluid seal. This is critical for the pump to work efficiently and to avoid problems such as cavitation, which can damage the pump and reduce its performance. The following is a typical working principle of the hydraulic activation function: 1. Water injection chamber: The plunger pump usually has a water injection chamber between the inlet and the pump chamber. The priming chamber is responsible for containing the liquid used to prime the pump. 2. Hydraulic mechanism: The hydraulic priming function uses hydraulic pressure to control the movement of a piston or diaphragm connected to the priming chamber. This piston or diaphragm creates a pressure differential that draws fluid from a source (such as a reservoir or sump) into the perfusion chamber. 3. Priming process: When the pump is started or priming is required, the hydraulic mechanism is activated. As the piston or diaphragm moves, it creates an area of low pressure in the perfusion chamber, causing fluid to be drawn into the chamber from the source. 4. Filling pump: When the filling chamber is filled with liquid, the air or gas present in the pump chamber is exhausted and discharged through the exhaust valve. The continuous flow of fluid into the perfusion chamber ensures that the pump chamber is properly filled and primed. 5. Fluid seal: After the pump chamber is filled with liquid, the hydraulic activation function helps to establish a proper fluid seal. This prevents air pockets or cavities from forming in the pump, which can result in reduced pumping efficiency, noise and potential damage. 42-R-41-D-G3AN-53-P-3-G-2-F-1-A-21-21-B-1-1-NNN-NNN 42R41DG3AN53P3G2F1A2121B11NNNNNN 42-R-28-C-G3AN-52-P-3-C-2-F-1-T-34-34-N-1-1-NNN-NNN 42R28CG3AN52P3C2F1T3434N11NNNNNN 42-R-28-D-G3AN-52-P-3-C-2-F-1-B-34-34-N-1-1-NNN-NNN 42R28DG3AN52P3C2F1B3434N11NNNNNN 42-R-41-D-G3AN-53-P-3-G-2-F-1-A-34-34-B-0-0-NNN-NNN 42R41DG3AN53P3G2F1A3434B00NNNNNN 42-R-28-G-E1A6-02-C-3-A-2-F-N-B-34-34-B-A-A-NNN-NNN 42R28GE1A602C3A2FNB3434BAANNNNNNN 42-L-28-C-G3AN-53-P-D-G-2-H-5-B-34-34-N-1-1-NNN-NNN 42L28CG3AN53PDG2H5B3434N11NNNNNN 42-L-51-D-G3AN-52-P-D-B-3-H-5-B-25-25-N-1-1-NNN-NNN 42L51DG3AN52PDB3H5B2525N11NNNNNN 42-L-28-D-E1A6-03-C-2-A-2-F-N-B-30-30-B-N-N-NNN-NNN 42L28DE1A603C2A2FNB3030BNNNNNNNN 42-L-28-C-E1A6-03-C-2-A-2-F-N-N-30-30-B-N-N-NNN-NNN 42L28CE1A603C2A2FNN3030BNNNNNNNN 42-L-28-C-ANNB-03-C-3-A-2-F-N-A-34-34-N-A-A-NNN-NNN 42L28CANNB03C3A2FNA3434NAANNNNNN 42-L-28-C-E1A3-03-B-3-B-3-F-N-B-25-25-B-A-A-NNN-NNN 42L28CE1A303B3B3FNB2525BAANNNNNNN 42-L-41-C-F4NN-73-J-D-B-2-F-N-N-21-21-N-A-A-NNN-NNN 42L41CF4NN73JDB2FNN2121NAANNNNNNN 42-R-41-D-ANN3-03-B-2-G-3-F-N-B-34-34-B-N-N-NNN-NNN 42R41DANN303B2G3FNB3434BNNNNNNNN 42-R-41-D-F4NN-73-J-3-C-2-F-N-N-28-28-N-A-A-NNN-NNN 42R41DF4NN73J3C2FNN2828NAANNNNNN 42-R-4A-D-G1A1-72-J-2-B-2-F-5-A-30-30-B-0-0-AAA-NNN 42R4ADG1A172J2B2F5A3030B00AAANNN 42-R-41-C-ANNB-03-A-N-A-2-F-N-N-34-34-N-A-A-NNN-NNN 42R41CANNB03ANA2FNN3434NAANNNNNN 42-R-41-D-ANNA-03-B-3-G-2-F-N-A-34-34-B-N-N-NNN-NNN 42R41DANNA03B3G2FNA3434BNNNNNNNN 42-R-41-C-F4NN-73-J-D-B-2-F-N-N-34-34-N-A-A-NNN-NNN 42R41CF4NN73JDB2FNN3434NAANNNNNNN 42-R-41-D-E1A6-02-B-D-G-2-H-N-B-25-25-N-N-N-NNN-NNN 42R41DE1A602BDG2HNB2525NNNNNNNNNN 42-L-28-C-E1A5-03-B-2-B-2-F-N-A-21-21-N-N-N-NNN-NNN 42L28CE1A503B2B2FNA2121NNNNNNNNNN 6. Controlled start: The hydraulic start function can precisely control the start process. The rate at which fluid enters the perfusion chamber can be adjusted, ensuring that the pump primes at an optimal rate without sudden surges of fluid that could flood the system. 7. Prevent cavitation: Cavitation is a phenomenon that occurs when the pressure in the pump drops to the point where the liquid begins to evaporate, forming air bubbles or cavities. When these air bubbles burst or implode when they enter high-pressure areas within the pump, they can damage pump components and reduce their efficiency. The hydraulic priming feature helps prevent cavitation by ensuring the pump is properly primed and full of fluid, minimizing the risk of low pressure areas that could cause vaporization. 8. Consistent Performance: Proper oil priming through the hydraulic priming feature ensures consistent and reliable performance of the pump over time. Without proper priming, the pump may experience irregular flow, pressure fluctuations, or even complete pump failure. 9. Ease of use: The hydraulic start function increases the convenience of plunger pump operation. The operator does not need to manually ensure that the pump is primed before starting, as the hydraulic mechanism handles this process automatically. 10. Versatility: Hydraulic priming is especially useful where the pump needs to be started and stopped frequently or where the inlet conditions of the pump change. This feature helps maintain operational efficiency regardless of changing conditions. 11. Maintenance Advantage: By reducing the possibility of cavitation and ensuring smooth operation, the hydraulic activation function helps to reduce maintenance requirements. A properly primed pump will experience less wear on its components. 12. Range of applications: Hydraulic perfusion is commonly used in various industries, including agriculture, construction, mining, oil and gas, and water treatment. Piston pumps with hydraulic actuation can be used in irrigation systems, high-pressure cleaning equipment, well pumps, etc. 13. Emergency: The hydraulic start function is especially valuable in emergency situations. If the plunger pump loses priming due to a sudden change in inlet conditions or unexpected shutdown, the hydraulic priming mechanism can help quickly restore the proper liquid level in the pump chamber, allowing the pump to resume operation immediately. 42-L-41-E-E1A5-02-B-D-B-2-H-N-B-34-34-N-N-N-NNN-NNN 42L41EE1A502BDB2HNB3434NNNNNNNNNN 42-R-28-C-E1A6-03-A-N-A-2-H-N-A-30-30-B-N-N-NNN-NNN 42R28CE1A603ANA2HNA3030BNNNNNNNN 42-L-41-E-E1A3-03-B-D-G-2-G-N-B-30-30-B-N-N-NNN-NNN 42L41EE1A303BDG2GNB3030BNNNNNNNN 42-L-41-E-E1A3-03-B-D-G-2-G-N-B-34-34-B-N-N-NNN-NNN 42L41EE1A303BDG2GNB3434BNNNNNNNN 42-R-41-D-E1A6-02-B-D-G-3-H-N-A-25-25-N-A-A-NNN-NNN 42R41DE1A602BDG3HNA2525NAANNNNNN 42-R-41-D-E1A3-02-B-D-B-2-H-N-N-34-34-N-N-N-NNN-NNN 42R41DE1A302BDB2HNN3434NNNNNNNNNN 42-R-28-D-E1A6-03-A-N-A-2-F-N-A-28-28-N-C-C-NNN-NNN 42R28DE1A603ANA2FNA2828NCCNNNNNN 42-R-28-C-E1A5-03-B-2-B-2-F-N-N-30-30-N-A-A-NNN-NNN 42R28CE1A503B2B2FNN3030NAANNNNNNN 42-L-28-D-E1A5-02-D-N-F-2-H-N-B-30-30-B-N-N-NNN-NNN 42L28DE1A502DNF2HNB3030BNNNNNNNN 42-L-28-C-E1A5-03-A-N-A-2-F-N-B-25-25-B-N-N-NNN-NNN 42L28CE1A503ANA2FNB2525BNNNNNNNN 42-L-41-D-E1A6-02-B-3-G-2-F-N-A-34-34-N-N-N-NNN-NNN 42L41DE1A602B3G2FNA3434NNNNNNNNNN 42-R-41-D-E1A5-02-B-2-B-3-F-N-A-28-28-N-N-N-NNN-NNN 42R41DE1A502B2B3FNA2828NNNNNNNNNN 42-R-41-D-E1A6-02-B-D-B-2-F-N-B-41-41-B-N-N-NNN-NNN 42R41DE1A602BDB2FNB4141BNNNNNNNN 42-L-41-E-E1A3-03-B-D-G-2-G-N-B-30-30-N-N-N-NNN-NNN 42L41EE1A303BDG2GNB3030NNNNNNNNNN 42-R-28-C-E1A5-03-C-2-A-3-F-N-B-34-34-N-N-N-NNN-NNN 42R28CE1A503C2A3FNB3434NNNNNNNNNN 42-R-28-C-E1A5-03-C-2-A-2-F-N-N-17-17-B-N-N-NNN-NNN 42R28CE1A503C2A2FNN1717BNNNNNNNN 42-R-28-D-E1A3-03-D-N-F-2-H-N-B-34-34-B-N-N-NNN-NNN 42R28DE1A303DNF2HNB3434BNNNNNNNN 42-R-28-C-ANNB-03-C-3-A-2-H-N-N-32-32-B-H-H-NNN-NNN 42R28CANNB03C3A2HNN3232BHHNNNNNN 42-R-2A-C-G2A1-53-U-3-B-2-H-1-A-30-30-B-0-0-AAA-NNN 42R2ACG2A153U3B2H1A3030B00AAANNN 42-R-28-C-G3AN-52-P-3-G-2-F-5-A-25-25-B-1-1-NNN-NNN 42R28CG3AN52P3G2F5A2525B11NNNNNN 14. Efficient system start-up: When starting the pump system from cold or inactive conditions, the hydraulic start-up function helps to quickly establish correct operation. It reduces the time and effort required to manually start the pump, making system startup smoother and more efficient. 15. Remote operation: In the case of remote operation of the pump or in difficult-to-reach locations, the hydraulic activation function can be controlled remotely or integrated into an automation system. This allows the operator to start the pump without direct physical contact, increasing operational convenience and flexibility. 16. Customization and adaptability: Manufacturers usually design adjustable hydraulic starting systems to suit different pumping requirements. This customization allows the function to adapt to various flow rates, liquid viscosities and inlet conditions, thereby optimizing the start-up process for specific applications. 17. Integration with safety features: In some cases, the hydraulic activation function can be integrated with safety measures. For example, if the priming chamber is not properly filled due to a lack of fluid supply, the pump may be programmed not to prime, preventing potential damage or unsafe operating conditions. 18. Technological advances: As technology develops, hydraulic actuation functions can benefit from improvements such as better control algorithms, sensor integration, and remote monitoring capabilities. These advances further increase the reliability and effectiveness of the start-up process.
