Here-comes-the-bearing-disassembly-non-destructive-disassembly-any-bearing-can-be-dismantled-like-this! There is all kinds of hydraulic pump and parts, engine and parts need to use bearing, and we could supply all kinds of bearing for you. However, when you have problems, how to dismantle in non-destructive way.Reasonable disassembly of the bearing in the case of interference fit is the core of bearing disassembly technology. When the disassembly force is so large that it cannot be dismantled by ordinary methods, and the disassembly force produced by conventional methods is likely to damage the bearing, an oil hole is generally designed at the end of the shaft, the oil hole extends to the bearing position and then penetrates radially to the shaft surface An annular groove is added, and a hydraulic pump is used to pressurize the inner ring to expand the inner ring during disassembly to reduce the disassembly force. For small bearings mounted on adapter sleeves with straight shafts, a hammer can be used to remove small steel blocks that evenly act on the end face of the bearing inner ring (Figure 7). For bearings mounted on adapter sleeves with stepped shafts, the use of hydraulic nuts can make bearing removal easier. After the bearing has been running for a period of time, there will inevitably be needs for maintenance or damage replacement. In the early development of the machinery industry, the popularity of professional knowledge was insufficient, and the awareness of safe operating procedures was insufficient. Today we will only talk about the disassembly of bearings .

Working principle of hydraulic sequence valve from wonepart The sequence valve is a pressure valve used when a hydraulic pump needs to supply two or more hydraulic actuators to operate in a certain sequence. The control pressure can be its own pressure or external oil pressure. Its structure and operating principle are very similar to the relief valve, and the difference is that the outlet of the sequence valve is directly connected to the actuator, and there is a special drain port. Any hydraulic pump parts or hydraulic valve we have, but we focus on kawasaki pump and parts and valves.

What should I do if the hydraulic pump or hydraulic valve system runs slowly and under speeds?
What should I do if the hydraulic pump or hydraulic valve system runs slowly and under speeds? The hydraulic system runs slowly, which is often referred to as under speed. Under speed does not work, but fails to meet the system requirements, so troubleshooting is difficult and there are many situations. The following summarizes the two situations and specific causes of hydraulic system under speed for your reference.

The working principle of various electromagnetic reversing valves makes you a hydraulic master
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.

Hydraulic valve
Hydraulic valve The hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure regulating valve. It is usually used in combination with an electromagnetic pressure regulating valve. It can be used to remotely control the on/off of oil, gas and water pipeline systems of hydropower stations. Commonly used for clamping, control, lubrication and other oil circuits. There are direct-drive type and pilot-type type, and the pilot type is used.

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.
