Introducing diesel generators to identify the color of smoke and start from preheating
Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, the component should be replaced and the clearance reduced. The normal mutual assistance clearance between the two is 0.05-0.12 mm .
Black smoke and ignition: It means that some diesel atomized particles in the cylinder can be secreted without being ignited. There are often three types of reasons for this: one is too much fuel, and the diesel engine is overloaded; the other is The fuel injection pressure of the injector is low, and the level of diesel atomization is poor; three, the fuel supply is too late, and the temperature of the idea is low.
Expulsion ideas: For diesel engines that supply too much fuel, properly reduce the fuel supply and operate within normal load; for diesel engines with low fuel injection pressure, correct or replace the fuel injectors in real time to catch up with the fuel injection pressure; For diesel engines that are fueled too late, the oil supply early angle should be cured. When recuperating, first unscrew the screws that do not change the keyboard on the gear at the time, and turn the keyboard clockwise to make the fuel supply early angle to 16 -19 degrees, the relative heave is 22.5-28.5 mm, together, the temperature of the hair is still at 80-90 ° C.
The diesel generator set emits white smoke and catches fire: it means that the atomized diesel injected into the cylinder is secreted without being ignited through the ceiling. There are three main types of reasons: First, the fuel injection nozzle is stuck, the pressure is lacking, and the diesel fog Poor chemical conversion; second, there is more atmosphere in the oil circuit, and there is water in the diesel; third, yes, and the black smoke is the same, and the oil supply is too late. Expulsion ideas: look at the injector and mediate or replace the injector; Zhang Wangyou Road, driving away the atmosphere in the oil road, and applying the example diesel; adjusting the fuel supply early in the morning, and the idea of healing when the black smoke is emitted.
The generator does not start in a while. Pay attention to some details from the beginning of preheating. Preheating: Before the start of the unit equipped with a preheater, employees can decide whether the unit is being preheated based on the ambient temperature, with a preheat button The control screen can be used to control the idea to start heating in order to reach the preheating goal.
Power on: Turn the key switch of the control screen from OFF to ON, and watch the background light on the panel.The control screen is powered on, and the fuel of the unit is turned on. The manipulator is also in professional form.
Start-up: The unit's control panel has an idle / full-speed switch. Users can choose whether to start at full speed or start at full speed according to the actual needs. Often, the idle time should not exceed 5 minutes. The unit must not run in idle mode for a long time.
Press the start button, and the time will last no more than 30 seconds. The idea is to start with the encouragement of the start motor. Once the start is successful, you can release the start button and the unit will come in running mode. Proposal: To increase the life of the start battery and start motor It is advisable to control the time of the first group in 5-10 seconds. If the start is not successful, you can pause the relative years and start the pace for the second time.
- 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
- 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
- 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 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
