Hydraulic systems serve as the core power source for a multitude of industries, providing comprehensive support for construction machinery, manufacturing equipment, aircraft control systems, and even automotive braking systems. Their operating principle is based on the transmission of power through an incompressible fluid—most commonly, hydraulic oil. However, despite the extreme durability of these systems, they […]

The hydraulic gear pump is a common type of positive-displacement pump found in hydraulic systems; its primary function is to convert mechanical energy into hydraulic energy. Its operating principle is based on the periodic variation of sealed volumes generated by the meshing of gears: as a pair of gears rotates within the pump housing, the

A positive displacement hydraulic pump (hereinafter referred to as a positive displacement pump) is a power component of a hydraulic system that relies on changes in the volume of a sealed working chamber to achieve oil suction and pressure. It is widely used in the field of fluid dynamics and motion control. Its rotating and

In hydraulic system design, energy transfer between the pump and actuators is not always linear. Although hydraulic oil is extremely difficult to compress, its bulk modulus changes under high pressure, and mechanical actions are often discontinuous. This leads to energy supply imbalances and severe pressure pulsations in the system. An accumulator, as an energy storage

When hydraulic oil is mixed with water, does its viscosity become thinner or thicker? The common understanding is that “oil mixed with water = thinner!” This is only half true. Once emulsification occurs, the viscosity will defy common sense and skyrocket. 1. First, debunk the common misconception that “oil mixed with water will always become

Hydraulic oil contamination is a key factor affecting the performance and lifespan of hydraulic systems. It not only leads to equipment failure but also shortens component lifespan and increases maintenance and operating costs. Therefore, understanding the sources, types, effects, and control methods of hydraulic oil contamination is crucial for ensuring the efficient operation of hydraulic

1. Install pressure gauge Install a 50 bar pressure gauge at the make-up oil pressure measuring port to check the make-up oil pressure of the make-up oil pump. This port is located on the side of the pump body. Install a 60 MPa pressure gauge at the system pressure measuring port to check the system’s

A hydraulic flow divider/synchronizing motor, as the name suggests, has two core functions: Flow Dividing: It precisely divides one input oil flow into two or more equal output flows, driving multiple actuators (cylinders or motors) to move synchronously. Flow Combining: During reverse operation, it combines multiple input oil flows into a single output. Its essence

1. Data Enhance the ability to monitor, collect, and utilize data generated by fluid power products and/or systems. By integrating sensors, IoT, and other technologies to access data, it becomes possible to better monitor component and system performance and identify potential maintenance issues, preventing these from leading to larger-scale unplanned downtime. This helps extend the

Hydraulic transmission relies on the volume change of the sealed oil chamber to transmit force and speed. Poor sealing will cause oil leakage, which will make the mechanism movement unstable, reduce volumetric efficiency, and pollute the environment. In severe cases, the pressure cannot be built up, causing the hydraulic system to fail to work. Therefore,
