A throttle is a valve that controls the flow of fluid by changing the throttle cross section or throttle length. The throttle valve does not have a negative flow feedback function, and cannot compensate for the speed instability caused by load changes. Generally, it is only used in situations where the load changes little or the speed stability is not high. The external structure of the throttle valve is not different from that of the shut-off valve, except that the shapes of their opening and closing parts are different. The opening and closing parts of the throttle valve are mostly conical streamlined, which can adjust the flow rate and pressure by changing the cross-sectional area of the channel. Throttle valve is used to reduce the pressure of the medium under the condition of extreme pressure drop. The flow rate of the medium between the throttle disc and the valve seat is so large that the surface of these parts is quickly damaged-the so-called cavitation phenomenon. In order to minimize the effects of cavitation, the valve disc is made of a cavitation resistant material (made of alloy steel) and is made into a streamlined cone with a tip angle of 140 to 180. This also allows the valve disc to have a larger opening height, which is generally not recommended. Throttle under small crevices.

The working principle of various electromagnetic reversing valves makes you a hydraulic master Dynamic diagram demonstration of the working principle of hydraulic valve, let you understand instantly! Hydraulic valve is an automatic component operated with pressure oil, but how does it work? What's the use? After carefully reading these 20 visual animations, you will understand! First of all, we need to know the types of hydraulic valves: Classification by control method: manual, electronic, hydraulic; Classification by function: flow valve (throttle valve, speed control valve, diverter manifold), pressure valve (overflow Valve, pressure reducing valve, sequence valve, unloading valve), directional valve (electromagnetic directional valve, manual directional valve, check valve, hydraulic control check valve); Classification by installation method: plate valve, tube valve, Superimposed valve, threaded cartridge valve, cover valve; classified by operating method: manual valve, motorized valve, electric valve, hydraulic valve, electro-hydraulic valve, etc.

How to properly store seals? Most sealing materials, including vulcanized rubber and other elastomers, often have more or less performance changes during storage. Improper storage methods will accelerate the aging of seals and even cause damage such as cracking of seals, which directly affects seal The life of the pieces. What factors should we consider when storing seals properly?

What is the difference between a hydraulic motor and a hydraulic pump? How should they distinguish between them? Hydraulic pumps and hydraulic motors are the most important components in hydraulic transmission systems. One is the power components, the other is the actuators, one converts the mechanical energy into hydraulic energy, and the other converts the hydraulic energy into mechanical energy. Achieving complex mechanical motion and providing a stronger mechanical torque, so what is the difference between the two? Where are they applied separately?

Common hydraulic seal classification Different types of seals are available depending on the application requirements, such as V ring, U ring, O ring, Y ring, etc.The original type of sealing ring is different, the medium resistance, hardness, and range of use are different! YD seals will guide you to learn more knowledge about hydraulic seal.

Commonly used basic seals knowledge and sealing working principle To achieve the "self-sealing" effect, we need to understand the qualitative changes in the pressure, viscosity, molecular weight and other factors of the working medium of the seal. Only by knowing more about the characteristics of the seals can you really understand what your product needs? Today, we wonepart editor willl explain the working principle of the seal and the basic knowledge of "self-sealing". Let YD seal tell you how the hydraulic seal work and how to get seal easily when you pick up seal.

Three minutes to learn how to adjust the main relief valve when excavator is powerless, the machine problem is solved! Speaking of the main relief valve, even the newly arrived machine is no stranger, enough to see the importance of the valve! It can be said that most of the excavator's inability to move, brakes and other faults are inextricably linked to the valve. Since the main relief valve is so important, how to accurately determine the fault when the valve is abnormal, and solve the fault accurately by adjusting the main relief valve by itself? Don't worry, the expert will introduce you in detail.

Axial piston pump common faults and troubleshooting methods. Do you know why piston pump has many problems, and how to choose the right way for troubleshooting？ As we manufacture all kinds of hydraulic pump, pump parts, piston assy, main valve, relief valve, regulators, bearing and so on.Today we interview our engineer colleague to explain to you the causes and choose the right way to solve the problem.

The hydraulic breaker is a new type of high-efficiency hydraulic shock vibration machine. It is a supporting working part of the excavator or loader. During operation, the high-pressure oil output from the working machine realizes the high-frequency reciprocating motion of the breaker piston in the cylinder. It is used for mining, metallurgical industry, municipal engineering, building construction, road and railway, etc.
