When the hydraulic pump is in use, due to some reasons, the pressure at a local position in the pump drops to the saturated vapor pressure of water at the corresponding temperature, and the water begins to vaporize and generate a large number of bubbles. Then, what harm do bubbles do to the hydraulic pump? […]

Standardized and safe use of hydraulic pumps can greatly reduce safety hazards in hydraulic systems and improve the stability of hydraulic systems. So, what are the eight precautions to pay attention to when using hydraulic systems? 1.Sometimes it is necessary to connect the oil to the housing of the hydraulic pump and motor to facilitate

On the industrial stage, the hydraulic press is like a silent but powerful giant. Although it is not often in the spotlight, it quietly promotes the development of many industries behind the scenes. Today, let us unveil the mysterious veil of the hydraulic press! 1. The wonderful application of Pascal’s law The working principle of

This paper introduces the specific composition and working principle of aircraft hydraulic systems, reviews the development history of civil aircraft hydraulic systems, and looks forward to the development trend of civil aircraft hydraulic systems. In response to the needs of future civil aircraft development, some new key technologies for civil aircraft hydraulic system research are

What is the internal principle and structure of the axial piston pump, and how does it suck and discharge oil? 1、Classification of piston pumps (motors): The types of axial piston pumps are the same as axial piston motors and are also divided into two categories: straight-axis axial piston pumps and inclined-axis axial piston pumps. Swash

1. Characteristics of hydraulic system failures (1) Debugging stage of new trial equipment ① Serious leakage at joints, fasteners, etc. ② Unstable speed ③ The valve core is stuck or inflexible due to dirt, causing the actuator to malfunction. ④ The damping orifice is blocked, causing the system pressure to be unstable or unable to

In the field of mechanics, there are many widely adopted mechanical structures, but for newcomers to this field, these classic mechanical structures may still be unfamiliar. This article aims to lead you to a deeper understanding of several popular mechanical devices. 1. Linear guide and linear motion assembly An example is a linear motion mechanism

1. Gear reducer Type: cylindrical gear reducer, bevel gear reducer, helical gear reducer, etc. Features: High transmission efficiency (90%-98%), suitable for high-power scenarios. Strong load-bearing capacity, suitable for heavy-duty industrial equipment (such as mining machinery, metallurgical equipment) with compact structure, but some types (such as spur gears) have high noise. Transmission ratio range: Single-stage transmission

1. Manual lubrication method This is the most traditional method and is suitable for situations where the lubricant is insufficient. The lubricant is replenished manually using a refueling device. However, this method is difficult to maintain a stable oil volume and there is a risk of forgetting to refuel, so it is mostly used in

1. “Obedient” control performance: function ≠ performance! What is the core task of hydraulic valves? It is not “being able to adjust pressure”, but “adjusting steadily and accurately”! For example: the same pressure regulating valve, some valves have very good data in the laboratory, but when installed on the equipment, the pressure fluctuation is as
