Key measures to deal with the dynamic load of the hydraulic unit of the plunger pump
The hydraulic unit of the plunger pump is subject to dynamic loads due to the reciprocating movement of the plunger. A plunger pump is a positive displacement pump that uses a reciprocating plunger or piston to displace fluid and generate flow. As the plunger moves back and forth, it creates pressure pulses in the hydraulic system, which cause dynamic loads on the pump components. Dynamic loads in hydraulic installations can have various effects and considerations: 1. Fatigue: The cyclic nature of the reciprocating motion can cause fatigue to the components of the hydraulic unit, especially in areas where stress concentrations occur. If materials are not properly designed to withstand these dynamic loads, repeated stress cycles can lead to the development of cracks and eventual failure. 2. Vibration: The reciprocating motion of the plunger will cause vibration of the hydraulic device and the surrounding system. Excessive vibration can impair pump performance, and additional measures (such as dampers or vibration isolators) may be required to minimize its effects. 3. Pressure pulsation: The reciprocating motion of the plunger causes pressure pulsation in the hydraulic system. These pulsations affect overall system performance and may require additional measures such as dampers or pulsation dampeners to smooth flow and reduce pressure fluctuations. 4. Lubrication: Dynamic loads in hydraulic units lead to increased friction and wear between moving parts. Adequate lubrication is essential to reduce friction, dissipate heat and extend pump life. To address the challenges posed by dynamic loading, piston pump manufacturers typically design hydraulics with robust materials and engineering to withstand cyclic stress. They can use materials with good fatigue resistance and employ proper heat treatment processes. Additionally, measures to reduce vibration, such as adding vibration-damping mounts or isolators, can help improve pump reliability and minimize impact on surrounding equipment and structures.

These mechanisms help control the deceleration of the plunger, reducing shock and stress on the system. In addition to the previously mentioned design considerations, additional measures can be taken to address dynamic loading challenges in piston pump hydraulic units: 1. Damping and buffering: In order to alleviate pressure pulsations during reciprocating motion and reduce shock loads, hydraulic systems may contain dampers or buffering devices. These devices help absorb and dissipate energy, smooth out pressure fluctuations and reduce stress on pump components. 2. Use of seals and packing: Proper sealing is critical for plunger pumps to prevent leakage and minimize fluid bypass between the plunger and cylinder. High quality seal and packing materials help maintain system efficiency, reduce energy loss and limit excessive hydraulic pressure on internal components. 3. Accumulator: Installing an accumulator in the hydraulic system can provide buffer for pressure pulsation and reduce the influence of dynamic load. Accumulators store pressurized fluid that can be released to smooth flow and reduce stress on the pump during rapid reciprocation. 4. Balance: In some designs, counterweights or balance mechanisms can be used to counteract reciprocating forces, thereby reducing vibration and dynamic loads. Balance helps improve overall pump stability and reduces wear on components. 5. Hydraulic oil characteristics: The choice of hydraulic oil also affects performance and response to dynamic loads. Viscosity, lubricity and other fluid properties should be carefully considered to optimize pump operation and reduce friction.

Monitoring and maintenance: Regular monitoring of pump performance, including pressure and flow measurements, can help identify any abnormalities or potential problems related to dynamic loads. Timely maintenance and replacement of worn parts can prolong the service life of the hydraulic device and ensure the reliable operation of the pump. It is worth noting that the design and implementation of these measures may vary depending on the specific application, size and type of plunger pump used. Additionally, adherence to industry standards and best practices for pump manufacture and installation is critical to ensuring the safety and efficiency of hydraulic installations under dynamic loading conditions. In summary, the dynamic loading of piston pump hydraulic units presents challenges related to fatigue, vibration and pressure pulsations. Proper design, material selection and use of damping devices, accumulators and sealing technologies are critical to meeting these challenges and ensuring reliable and efficient performance of the pump over its service life. Regular maintenance and monitoring play a vital role in extending the life of the pump and minimizing the risk of accidents.
