How to quickly and accurately find the fault location that caused the unit's low oil pressure

发表时间:2017-12-23 Article source : Couch motor manufacturersPublished time: 2017-12-23

In actual operation, the low oil pressure of diesel generators is one of the common faults. When the oil pressure is low, it takes time and effort. First of all, I would like to introduce to you that there may be many reasons for the low oil pressure of the diesel generator set. For example, the main and connecting rod bearings or camshaft bearings are loose, the main oil pipes are damaged, loose connections, and the valve pressure is Looking back, the pump is exhausted and the filter is dirty, etc.

How to quickly and accurately find the fault location that caused the unit's low oil pressure

In general, the method to determine the fault location is to find the fault location from the oil pump, and then find the fault location one by one. This method is time-consuming, time-consuming, manpower and material resources, and the location of the fault can be determined by using the smoke blowing method. The method is intuitive, simple and fast, avoids unnecessary disassembly, and greatly improves work efficiency.

The specific method is as follows: after the oil quality, oil pressure gauge and oil pressure sensor are normal, after removing the oil pan, remove any screw main cylinder body, and compress with a screw hole hose on rubber; then, after taking a breath of smoke, the smoke The part that will blow into the oil passage, and the smoke will be observed. This is the fault location, which makes the oil pressure lower. If there is no smoke from all parts, it can be considered an engine oil pump or filter.

In short, through the "smoke blowing method", it is not necessary to find the fault location quickly and accurately as part of the inspection, thereby solving the problem of low oil pressure of the diesel generator set, enabling the unit to resume normal work as soon as possible, and ensuring the stability of power supply enterprises.

    In some places far away from the power supply, the only option is to use a diesel generator to ensure the power supply. This small-scale power generation equipment is widely used in remote areas and is of great significance to local residents. But what should I do if the diesel generator fails? What are the specific uses of diesel generators? Let ’s take a closer look at “What are the causes and uses of diesel generator failures?”

    The assembly place needs to be well ventilated, the generator end should have sufficient air inlets, and the diesel engine end should have excellent air outlets. The area of the air outlets should be more than 5 times larger than the area of the water tank. The periphery of the assembly site should still be clean to prevent the formation of surrounding installations. Cargoes with corrosive gases and steam such as acid, alkali, etc. Fire extinguishing devices should be equipped if required. If used indoors, the smoke exhaust pipe must be opened to the outside, the diameter of the smoke pipe must be ≥ the diameter of the smoke pipe, and the pipe connected The elbow failure should exceed 3 to ensure the exhaust smoke circulation, and the pipe should be tilted downward by 5-10 degrees to prevent rainwater intake; if the exhaust pipe is assembled vertically upward, then

    The diesel generator set can be repaired and maintained in the middle of 6000-8000 hours. The overall control text is as follows: Check the wear level of the diesel generator set valve, the valve seat of the diesel generator set, and repair or change the diesel generator set if necessary; Check the occupational status of PT pumps and fuel injectors for leased generators, and repair and adjust if necessary. Check and adjust the torque of connecting rods and fastening screws of diesel generator sets; check and adjust the valve clearances of diesel generator sets; adjust leases The course of the injector of the generator; check the tension of the belt of the mediator fan charger; scrub the intake manifold

    Regarding the generator leasing problem in the use process, what should I do? This anomaly is a bit of concern for many customers who want to rent a generator. Let ’s answer it. At the beginning, as a focused generator set rental supplier The maintenance of the settings and the handling of hidden dangers in advance are real-time, thoughtful, and focused. Maybe the machine is out of the warehouse with a disease. Secondly, no supplier can promise that the settings supplied by me will not be out of order. Even new The settings are also different. For this reason, regarding the unexpected problems in the utilization process, we will send the customer to the promised hour for disposal, if necessary
