As there are thousands of materials, therefore, we will show some special one for your reference.

  • An engine is a machine that can convert other forms of energy into mechanical energy, including, for example, an internal combustion engine (gasoline engine, etc.), an external combustion engine (Stirling engine, steam engine, etc.), an electric motor, and the like. For example, internal combustion engines usually convert chemical energy into mechanical energy. There are many cases happen to engine, for wonepart we have experience of engine repair and rebuild projects, if your engine have the following problems, then you will check the following reasons as reference: 1. When the start switch is engaged, the engine crankshaft will not rotate Possible reason • Battery output is too low • Defective wire or switch • The electromagnetic switch of the starting motor is faulty • The starting motor is faulty • Intrinsic problems affecting the rotation of the engine crankshaft 2. Start the motor crank, but the engine cannot start Possible reason • No fuel in the fuel tank • Poor fuel quality • The fuel filter is dirty • The fuel pipe is dirty or damaged • Low fuel pressure • There is air in the fuel system • The fuel system and engine are not at the correct timing • The exhaust valve is always open (the fuel does not have high enough pressure to start the engine) • Turning speed is too low • No fuel in the fuel injection pump housing

  • 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.

  • Excavator engine burning oil refers to the fact that the oil loss during the excavator operation is higher than that of the same type and the same type of excavator oil, and the operation is accompanied by the phenomenon of blue and black smoke. Excavator engine burning oil is one of the more serious faults in the engine failure of excavator. Let's understand the reasons and solutions for the burning of excavator oil: The breakdown of excavator burning oil failure classification: a large amount of blue smoke is emitted at startup; a large amount of blue smoke is emitted when refueling; A large amount of blue smoke is emitted from the oil filling port; the consumption exceeds the normal requirement.

  • Do you know the functions of the sensors and solenoid valves on the excavator? For environmental protection, excavators are now mostly EFI vehicles. Diggers often encounter various alarm codes, and these alarms are mostly caused by sensor or solenoid valve failures. Here are the ten sensor and solenoid valve positions and functions on the engine.If you are looking for engine parts, pls visit our online website http://www.wonepart.com/product-list/engine, you could find many items, and if you could not find pls email us info@wonepart.com.

  • 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.

  • 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?
