Selection and usage precautions of high-pressure plunger pump
Determine the working condition of the medium: Large particles are not allowed to appear in the medium conveyed by the plunger pump, otherwise it may cause work failure. Stainless steel plunger pumps should be selected for occasions with requirements for iron pollution, and anti-corrosion plunger pumps should be selected for acidic or alkaline media.

Application fields of high-pressure piston pumps
Hydraulic press: Provides high-pressure hydraulic oil to drive the hydraulic press for various machining operations. Construction machinery: such as excavators, loaders, etc., used to provide high-pressure hydraulic oil to drive working devices for operation.
Characteristics of High Pressure Piston Pump
High rated pressure: The operating pressure of high-pressure plunger pumps should generally be between 10MPa and 100MPa, which can meet the requirements of high-pressure applications. Compact structure: The high-pressure plunger pump has a small volume, light weight, and is easy to install and maintain.
Working principle of high-pressure plunger pump
High pressure plunger pumps produce periodic changes in the volume of the working chamber through the reciprocating motion of the plunger in the working chamber of the hydraulic cylinder, or through the periodic elastic deformation of flexible components such as diaphragms and bellows in the working chamber.

Application scenarios of hydraulic pumps
Gear pump: suitable for scenarios where oil cleanliness requirements are not strict and prices are sensitive, such as hydraulic systems in machine tools, hydraulic presses, vehicles, construction machinery, and plastic injection machines.
Working principle of hydraulic pump
Hydraulic pumps rely on periodic changes in sealing volume to achieve oil suction and pressure. When the prime mover drives the pump to rotate, the sealing volume inside the pump increases, forming a local vacuum.
