Necessity of Inspection of Oil Valve Wear and Its Testing Tools
In the diesel fuel system of the three pairs of pieces, the fuel injector coupled with a special nozzle detector to test its performance, fuel plunger coupling by rotating the pump camshaft (high pressure tubing and injector connected) and With the feel you can know the couple good or bad, without disintegration testing, only the oil valve can not detect the pump test, the general test only its opening pressure, as for its one-way sealing, pressure ring sealing performance can not be tested , Thus bringing many difficulties to the fuel system fault diagnosis and repair work. During the repair of the pump often users complain about the rough work of its diesel engine, unstable speed and low speed knocking cylinder serious, but the injector atomized well, the other parts of the diesel engine is normal, so that the problem of high pressure oil pump repair. Check the pump when the fuel supply time, governor, fuel plunger seal, the valve opening pressure are normal, the plunger sleeve set screw and plunger adjustment ring gear locking screw and the valve seat are Not loose, just a few cylinder oil was significantly higher. If the high cylinder oil transferred to normal, often the fault still. If the oil tank before the oil level adjustment will be out of the valve, the fault can be completely ruled out, why? As we all know, the oil valve is a one-way valve, its role is to ensure that diesel reaches a certain pressure before entering the high-pressure tubing, but also to prevent the high-pressure diesel from the high-pressure tubing back into the fuel pump, and at the end of each fuel supply, The pressure ring can rapidly reduce the pressure of diesel oil in the high-pressure fuel pipe to prompt the fuel injector to cut off the oil quickly to prevent dripping. If the relief valve with the relief valve seat with the gap is too large, the decompression effect worse, high pressure tubing residual pressure than normal high. In this way, when a total of the plunger upward pressure oil, on the one hand the oil valve to rise, on the other hand the diesel fuel across the pressure relief ring and the excessively large gap between the valve seat open cone directly into the high-pressure fuel pipe, which in fact Equivalent to the starting point for oil supply in advance. If we only adjust the pump when the corresponding cylinder less fuel supply, although the solution to the problem of uneven cylinder fuel, but the original partial cylinder fuel supply is still ahead of other cylinder oil supply, diesel engine failure can not be completely solved, This shows that the valve on the oil chamber is very necessary. Because, we diagnose the fuel system failure, do not just look on the governor and the fuel plunger and nozzle, repair the pump, be sure to check the quality of the oil valve, otherwise it will make The problem is complicated and can not even be solved. However, there is a lack of equipment to check the quality of the oil valve. The repair shop often uses a pressure gauge to connect to the high-pressure oil pipe connector to check the quality of the oil plunger while checking the quality of the oil valve. However, this can only check the tightness of the oil valve cone, Measured the decompression ring with the valve seat with the quality. To this end, we trial-produced a simple and practical tool for the quality inspection of oil valves, maintenance work to bring a lot of convenience, are recommended as follows. Use, the first oil valve into the fixture, and then the pipe joint 1 and injector nozzle connected to the test tube, with the help of the nozzle tester hydraulic pressure can be. According to our experience in the use of maintenance, requirements: Conical sealing performance: pressure from 21MPa down to 1.5MPa time not less than 50s, or need grinding grinding cone. Decompression ring sealing performance: the first screw with the valve from the valve top jacking 0.3mm, pressure from 21MPa to 2MPa time not less than 3s, or scrapped.
