In a plunger pump, the torque generated by the rotation of the drive shaft is transmitted to the plunger through the mating surface between the tapered shaft and the coupling. A plunger pump is a type of positive displacement pump commonly used in a variety of applications that uses the reciprocating motion of a plunger to move fluid and generate pressure. Here is a more detailed explanation of how a plunger pump transfers torque: 1. Cone shaft: Cone shaft, also known as swash plate or cam plate, is an important part of the plunger pump. It is usually mounted on the drive shaft and is responsible for converting the rotational motion of the drive shaft into linear motion of the plunger. 2. Coupling: The coupling is a connecting element connecting the cone shaft and the plunger. It acts as an intermediary that transfers the rotary motion of the cone shaft to the linear motion of the plunger. 3. Eccentric motion: Taper shafts are designed with eccentric or angled profiles. As the drive shaft rotates, the eccentric motion of the cone shaft causes it to tilt or reciprocate. 4. Plunger: The plunger is a cylindrical part that reciprocates in its respective cylinder bore. A coupling connects the reciprocating motion of the cone shaft to the plungers, forcing them to move in and out of the cylinder bore.

Fluid Displacement: As the plungers reciprocate within the cylinder bore, they create volume changes, drawing fluid into the cylinder during the suction stroke and pushing it out during the discharge stroke. This process creates fluid flow and builds up pressure at the pump outlet. 6. Sealing mechanism: The plunger pump uses sealing elements, such as packing or seals, to prevent fluid leakage along the length of the plunger and ensure efficient operation. 7. Variable displacement: Some plunger pumps are designed with a variable displacement function. By adjusting the angle or position of the cone shaft or changing the stroke length of the plunger, the displacement of the pump can be changed. The advantage of variable displacement piston pumps is that flow can be adjusted according to system needs, which increases energy efficiency and reduces wear and tear on components. 8. High pressure application: plunger pump is especially suitable for high pressure application. The reciprocating motion of the plunger, coupled with the ability to effectively seal off fluid, allows them to generate and maintain significantly higher pressures than other types of pumps. 9. Smooth flow output: When properly designed and operated, a plunger pump can provide an almost pulsation-free flow output. This characteristic is critical for applications requiring steady, smooth fluid flow, such as precision spraying, chemical dosing and metering. 10. Wide range of fluids: The plunger pump can handle a variety of fluids, including high viscosity, abrasive particles and corrosive liquids. They can also be used with non-lubricating and lubricating fluids, making them suitable for a wide variety of industrial processes. 11. Durability and service life: The solid structure and design of the plunger pump contributes to its durability and long service life. When properly maintained and operated within specified parameters, piston pumps can provide reliable performance even in demanding continuous duty applications.

Low slip: Piston pumps generally have low slip, which means that there is minimal backflow of fluid from the high pressure side to the low pressure side during operation. This feature increases the efficiency of the pump and enables it to maintain a relatively constant output flow. 13. Suitable for high-speed operation: The plunger pump can operate at a relatively high speed, enabling it to provide higher flow and meet the needs of certain high-flow applications, such as high-pressure cleaning systems and power units. 14. Multi-piston configuration: The plunger pump usually adopts a multi-piston configuration, and multiple plungers are arranged radially around the cone shaft. This design provides balanced loading on the shaft and ensures smooth operation. 15. Pre-pressurization system: Piston pumps can be used in pre-pressurization systems, where the pump continuously supplies pressurized fluid to downstream equipment, thereby reducing the need for additional auxiliary pumps. The proper piston pump must be carefully selected for a specific application, taking into account factors such as flow rate, pressure requirements, fluid properties, system design and environmental conditions. Proper installation, regular maintenance, and adherence to manufacturer guidelines are key to optimizing the performance and life of your displacement pump in any given application. Working with an experienced hydraulic engineer can help ensure that the pump is properly selected and integrated into the overall system design.
