In 2024, Parker Hannifin announced the launch of a new truck hydraulic pump—the F4 series. This article mainly explains some features of this pump and see if they can be applied to other application areas. 1. What’s special about this pump? This pump has two main features: (1) It’s a dual-flow pump, meaning it has […]

On construction site loaders, farm tractors, and ocean-going vessels, a reliable steering system is crucial for safe operation. You may not have noticed, but more and more large equipment is now abandoning traditional mechanical linkages in favor of “mechanically linked” hydraulic steering technology—hydrostatic steering. 1. The Evolution of Hydraulic Steering: Three Generations of Technological Iteration,

As an important power device, servo motor plays a key role in many fields. So, how can we choose a suitable servo motor? This requires us to have a detailed understanding of its performance parameters. 1. Main performance parameters of servo motor (1) Rated power: This refers to the power that the motor can continuously

1. Depressurize the Hydraulic System Before Maintenance Hydraulic systems typically operate under immense pressure, so improper handling during maintenance can lead to catastrophic failures, including explosive ejection of hydraulic fluid and serious injury. To mitigate these risks, the system must be completely depressurized before any maintenance or repair. Proper depressurization ensures a controlled and safe

1. Power to weight ratio is required to adopt hydraulic transmission As the working pressure of the hydraulic system can be higher (for example, 32MPa or higher), so the corresponding transmission of power and actuators (hydraulic cylinders, hydraulic motors) is greater than the ratio of weight. Electrical transmission or pneumatic transmission can transmit power, and

Valves are essential in many devices and play a very important role. In this issue, let’s take a look at some of the most common valves in Heating, Ventilation, and Air Conditioning system. 1. Four-way valve Four-way valve, a hydraulic valve term, is a control valve with four oil ports. (1) Working principle of four-way

1. Excessive wear of components: Excessive wear of internal components of hydraulic motors such as bearings and plungers can lead to increased vibration and noise. This wear may be caused by long-term use, poor lubrication or material fatigue. 2. Air enters the system: When there is air in the hydraulic system, it will cause cavitation

In hydraulic systems, gear motors, plunger motors and gerotor motors are the three most common hydraulic drive devices. Their respective structural characteristics and performance make them suitable for different application scenarios. This article will analyze in detail the differences between these three types of motors in terms of their use environments to help you choose

Intelligent hydraulic presses belong to high-end manufacturing equipment, primarily targeting the design, manufacturing, and use of hydraulic presses. They utilize advanced intelligent technologies such as information perception, decision-making, and safe execution to form a human-machine system comprised of human experts and intelligent machines. This achieves optimal organization and allocation of resources such as products, tools,

Loose hydraulic hose joints are a common problem in construction machinery. If not addressed promptly, they can lead to minor issues like oil leaks, or even serious problems like hydraulic system failure or safety accidents! Let’s see how to solve the problem of loose hydraulic hose joints and bring your equipment back to full working
