We, wonepart.com also supported construction machinery spare parts in this war epidemic to refuel China. For our construction machinery parts, we have all kinds of seal,seal kits, piston seal, nok seal, excavators seal kits, backhoe loader seal kits, pump and parts, engine and parts, hydraulic breaker and breaker parts to build hospital.According to foreign netizens' evaluation, the army of excavators and construction workers who are constantly on the road and supplies to Wuhan are "continuously preparing for this battle at an incredible speed."

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 .

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.

Case Study on Difficulties in Starting a Diesel Engine Reasons and troubleshooting methods for the difficulty of starting a diesel engine ①　The diesel engine does not run for a long time: the oil return pipe must extend below the diesel liquid level ②　there is a small amount of air in the low-pressure pipeline: exhaust ③　the crankshaft speed signal and camshaft signal are too weak, and the synchronous judgment time is longer Long: readjusted ④　The ambient temperature is too low, and the preheating device is invalid: Replace the preheating device ⑤　The quality of diesel and oil is too poor to meet the standards: Replace the standard oil ⑥　Starter or flywheel ring gear teething: Replace the starter and flywheel teeth Ring ⑦　Piston ring, cylinder liner is worn or valve is not tight: Replace piston ring, cylinder liner or valve seat, valve ⑧　Exhaust brake butterfly valve stuck in closed position, resulting in poor exhaust: Replace butterfly valve Slow ⑨　rail pressure buildup caused by excessive fuel volume: Replace injector assembly fuel tank inlet and return pipes do not meet design requirements for inner diameter and pressure

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.
