Strictly in accordance with the provisions of the requirements of the unit routine maintenance, to ensure reliable operation of the unit
Good maintenance can ensure reliable operation of the unit. Under normal use, the maintenance work should be carried out in accordance with the provisions of the daily maintenance, weekly maintenance, monthly maintenance requirements. Through these provisions of the maintenance, can be found in a timely manner whether the unit has an abnormal sound, action, appearance, temperature, pressure and odor abnormalities and other fault phenomena, so that timely inspection and adjustment of the unit, and then targeted to solve to ensure that the unit is running in the best state. In these maintenance requirements, special attention should be paid to the following three aspects of inspection and maintenance:
(1) lubrication system inspection and maintenance. This type of unit due to the existence of running parts, running parts of poor working conditions, mostly in the high temperature, high impact load state, need to lubricate more parts of the lubrication system, the reliability of the requirements of the lubrication system is more demanding, so we should pay attention to checking the oil quality of lubricant system, oil level, oil temperature and oil pressure, pay attention to the centrifugal filter and oil filter cleaning, to avoid lubrication caused by bad The wear and tear of the components of the unit is aggravated, shortening the service life of the components of the unit and increasing the maintenance workload;
(2) Check and maintenance of the air filter. If the air filter is running well, it will effectively avoid excessive pressure drop caused by large inlet resistance, which in turn causes oil leakage from the turbocharger; it can also avoid the turbocharger compressor wheezing phenomenon caused by reduced flow. Therefore, it is necessary to regularly clean the air filter, if necessary, replace the new filter element. In humid areas can be drawn off the paper filter element.
(3) Related gap and angle check and adjustment. Mainly spark plug gap, valve lash and gas timing checks and adjustments.
After the unit has been running for some time, the spark plug gap will become larger, which is a normal phenomenon. Ltd., for example, when the gap increases to 0.89mm, the spark plug will misfire phenomenon, resulting in unstable operation of the unit, or even stop, so it should be regularly checked and adjusted, while eliminating the spark plug and its threads of carbon to ensure that it works well. In addition, after a long time of operation, due to the wear and loosening of the gas distribution mechanism, it will cause changes in the valve lash, which should be checked and adjusted regularly. Gas distribution timing under normal circumstances do not need to be adjusted, when the unit's working condition of the cylinders appear abnormal, you should first check whether the pointer on the stop indication position is correct, check the transmission system of the gear drive mark is aligned, the whole system of assembly relations and valve lash is correct. If after checking and adjusting, there is still a big difference with the specified value, then you should consider the camshaft or gear drive parts are damaged, if necessary, repair or replacement. Improvement of maintenance tools, equipment modification, improve maintenance efficiency
The G12V190ZLT - 2 type of internal mixing gas engine is designed for the characteristics of refining and chemical tail gas with high hydrogen content, it adopts a mechanical mixing method, timed to open the gas valve will be injected into the cylinder combustible gas, so that the gas and air in the cylinder mixing, combustion. This through the supercharger, the gas intake pipe is always non-combustible pure air, to avoid the flashback problem, to solve the refinery tail gas in the high hydrogen content can easily cause the risk of explosion in the intake pipe. However, because the gas recovered from the refinery contains H2 S and NH3, the spool and cavity of the regulator valve installed on the fuel gas line is also found to have NH4 HS crystallization. When condensed liquid hydrocarbons are mixed with the gas and enter the fuel system, the liquid hydrocarbon deflagration releases a large amount of radiant heat, causing damage to components that are in contact with the hot flue gases due to exposure to excessive temperature conditions. Due to the phenomenon of deflagration occurs from time to time, the unit's piston, cylinder, intake and exhaust valve, intake and exhaust valve seat and other frequent failures, service life is reduced, the amount of maintenance is quite large. Due to the installation of the piston is to use a random ring clamp (by two half-ring through a pin connection and become a half-ring at the pin is welded to a handle, two half-ring on the other side of each welded to a handle. The piston rings are brought together to ensure that the piston group can enter the cylinder smoothly. In the use of the process we found: the use of ring clamp maintenance personnel in the installation of the whole process must be on the one hand by holding the ring clamp pin shaft on the other side of the two handles to ensure that the ring clamp in the state of together, on the other hand, but also to pay attention to the bolts on the body will not prevent the ring clamp on both sides of the handle of the drop, the installation of the rather laborious. In order to install conveniently and quickly, we used the scrapped cylinder liner to process a taper sleeve (the inner and outer diameters of the sleeve are basically the same according to the original dimensions of the cylinder liner, and only processed a section of 20mm long taper at the top, and in the taper and the junction of the inner hole to pour a large rounded corner, so as to facilitate the piston ring can be pressed into the taper sleeve smoothly. In the piston installed in the cylinder before the taper sleeve in the piston ring, so that all the piston ring are in normal use of the compression state, the installation just need to put the piston skirt in the cylinder, and then slightly adjusted, so that the cylinder and the taper sleeve concentric, and then gently with the hand to slowly push the piston into the cylinder. This not only reduces the labor intensity, but also improves the installation efficiency.
According to the principle of fault analysis and troubleshooting to find faults, improve the accuracy of finding faults
The occurrence of faults, pay attention to the phenomenon of failure to analyze the cause of the failure, combined with the principle of analysis of the structure of the table and the inside, the first easy to find after the difficult. Failure should first consider the following three questions: (1) What phenomena occur before the failure? (2) What maintenance and overhaul work has been done before the failure? (3) Have you encountered similar situations before? How was it handled? In addition, when the unit is allowed to judge the problem during operation, it can be judged during operation. For example: if you find that the exhaust temperature is too high or the exhaust temperature of one cylinder suddenly changes, you should first check whether the gas regulator valve of each cylinder is loose under the running condition of the equipment; if the problem still exists after excluding the gas regulator valve, you should stop the machine to check whether there is any problem in the ignition system, such as spark plugs and ignition coils, etc.; if there is any abnormality in the exhaust temperature, you should distinguish between a single cylinder and the whole cylinder with abnormality in the exhaust temperature, and consider the problem of single cylinder abnormality, and consider the problem of single cylinder abnormality. Single cylinder abnormal, should consider whether the instrument display is not normal, can be used to measure the thermal potential or inverted line to be ruled out; if the whole abnormal, should consider whether the gas concentration changes or whether there is ignition
Bad fire. Troubleshooting, when there is no effective means of identifying the cause of the failure, you can use the replacement method. For example, when the ignition controller is suspected of malfunctioning, check and adjust the ignition controller needs to be connected to a PC computer or special portable programmer to adjust, but basically the maintenance unit will not be configured with these testing equipment, then you can remove the ignition controller on the other standby equipment to install after the boot operation, through the observation of similar failures whether to judge whether the ignition controller is damaged again.
This is the first time I've seen an ignition controller damaged.
