Use Xinshengan natural gas generator, including precautions before and after the unit is started, during operation, and storage! What is the specific content? The following editor will introduce to you what matters should be paid attention to before and after the start-up and use of the gas generator set?Preparations before starting the gas generator set: Check and adjust the condition of the whole unit before starting. The connection and fixing of each component must be correct. The cooling water system of the engine and the electric starting system are all connected reliably, without dripping or loosening, and the switch is flexible. The lubrication system is good, and the gas supply system and ignition system are confirmed to be normal. Otherwise, it must be overhauled and adjusted correctly before starting.Idle operation after starting: After the preparation is normal, open the gas valve, connect the starting power, turn on the key, and press the button to start the unit. When the unit is started, pay attention to the oil pressure gauge, there is a normal oil pressure, do not be careless. After starting, run at idle speed for a period of time. One is to observe whether the operation of various parts and components is abnormal, whether there is abnormal sound, and deal with and solve the problem. Idling is also used to heat up the machine. In winter, this temperature rise is very important and will benefit the use of the machine.Normal load output: After the idling speed is observed, and the unit has reached the temperature (observe the water temperature gauge), the ESC "throttle" can be manipulated to increase the unit speed to the calibrated working speed, and the voltage and frequency of the unit can be adjusted to reach the calibration. Value, you can switch on to the outside and output the load. In order to use external load when closing, it is recommended to turn the speed (frequency) of the empty car slightly higher before closing. When the load changes, pay attention to the speed control "throttle" handle, that is, the potentiometer of the electronic governor, to adapt to the output, so that the voltage and frequency are stable.1. The engine room of gas generator set should be far away from open flame area;2. The engine room of the gas generator set should be spacious and bright, and ventilation fans should be installed to ensure good ventilation;3. When installing the gas generator set, the chassis and foundation should be leveled with flat irons. The contact area should be more than 60%, and the distribution should be even;4. Explosion-proof measures should be adopted for indoor installation of lighting, switches, circuits and electrical appliances, and they should be firmly fixed;5. The engine room of the gas generator set should meet the fire protection requirements and be equipped with fire extinguishers and other fire fighting equipment;6. A combustible gas alarm device is installed in the engine room of the gas generator set, so that when combustible gas leaks, it can be discovered in time;7. The inner diameter of the main external pipe of the gas pipeline of a single gas engine below 60kw should be no less than 2 inches, and the inner diameter of the part close to the engine should be no less than 1 inch! Gas generator sets above 60kw are 3 inches and 2 inches respectively. In addition, a gas valve (stainless steel ball valve), a type drain valve, and an anti-backfire device must be installed. The welding slag should be cleaned up after the gas pipeline is welded (using high-pressure air);8. The fuel gas must be desulfurized, dehydrated, and dust removed, with a flow rate ≤0.25Nm3 and hydrogen ≤10%;9. Demineralized water must be used for cooling water of gas generator set.
1.Engine power decreases and fuel consumption increases. Due to the high altitude, the air density and pressure decrease.The engine's charge, cylinder compression pressure and temperature also decrease, causing the mixture become too thick and causing poor combustion and black smoke. This situation can be solved by adjusting the fuel injection pump to reduce the fuel supply until the exhaust does not smoke.2.Adjust the fuel supply advance angle. When the altitude is generally between 2000 and 3000 meters, it can be advanced by 1°-2°. When it is 3000-4000 meters, it can be advanced by 2°-4°.3.The battery is prone to fail. As the boiling point of water decreases, the water in the battery is easy to evaporate, lowering the liquid level and affecting the normal operation of the battery. Therefore, the height of the battery liquid level should be checked frequently and should add distilled water in time.4.The engine temperature is too high and wear is aggravated. As the boiling point of water is lower, the cooling water is easy to boil.It will cause the engine to overheat and reduce the performance of the lubricating oil, affecting the service life of the engine.Attention must be paid to the engine water temperature and the cooling water should be added at any time. Appropriate lubricants should be selected according to the original factory required, and the quality of lubricants be guaranteed. 5.The temperature is low and it is difficult to start. When the temperature is lower than -10℃, it must be started with hot water. If it is started without heating, on the one hand, it is easy to damage the engine, and on the other hand, the electric energy of the battery will be quickly consumed. In the case of low temperature, when the parking time is too long, the water must be drained to prevent the engine and radiator from freezing and cracking.
As electricity becomes more and more important to our lives, diesel generators, as independent power generation equipment, provide emergency power in the event of a power failure. Therefore, diesel generators are available in many places. How to properly maintain them when not in use? Next, Xinshengan Power will give you an introduction.As a matter of fact, most of the time the unit is in standby mode, and there are relatively few opportunities to actually put it into use. Usually, it is mostly based on test machines and lacks more complete inspection and maintenance methods. But this kind of emergency backup power is indispensable. How to ensure that the generator can be powered in time in an emergency when the generator is used less often, and the operation is safe and reliable, and it can be shut down immediately after the power failure.Look at the following related diesel generator inspection and maintenance steps.The first step is to check the battery packSince the backup power supply is not often put into use, the key to whether the generator can start normally lies in the maintenance of the battery. If there is a problem with the battery pack, the more common situation is: there is voltage and no current. At this time, you can hear the sound of the solenoid valve in the starter motor, but the coupling cannot be moved.There are three reasons why the battery pack cannot stop due to problems:1. Using the method of stopping charging the battery during the test machine will result in insufficient battery power.2. The mechanical oil pump is driven by a belt, and the pump oil volume at the rated speed is very large. However, the battery pack is insufficiently powered, which causes the spring plate in the shutoff valve to be blocked due to insufficient suction of the solenoid valve to spray from the four oil outlets when the machine is stopped. The fuel can not be shut down.3. Domestic batteries usually have a life span of two to three years and are not replaced regularly.The second step is to check the start solenoid valveWhen the generator is running, people have summed up a set of inspection methods of "one look, two listen, three touch, and four smell". Listening at startup is a very important step. Take the Cummins generator set as an example. Just press the start button and it will start after three seconds. Within these three seconds, two "clicks" can be heard. Once the second sound is not heard, check whether the start solenoid valve is working properly. If the solenoid is blown out, the generator will of course not start.Third, the inspection of diesel oil, lubricating oil and antifreezeBecause the generator set is in a static state for a long time, the various materials of the set itself will undergo complex chemical and physical changes with oil, cooling water, diesel, air, etc., which will "discharge" the set. For this reason, attention should be paid to the oil and water problems, and timely Replace or supplement.
The generator set has been used for a long time, and some minor faults are always inevitable. When the engine water temperature is too high, the water tank boiling phenomenon will occur, so what should we do whne this happens? The user can observe the violent water overflow in the radiator or expansion tank. Open the water tank cover to prevent burns. Then when the generator set has the phenomenon of boiling the water tank, we should proceed as follows:1. Don't turn off the engine immediatly, so as not to burn the cylinder bed, pull the cylinder, and cause greater damage to the unit.2. Do not try to open the water tank cover, otherwise it is very likely that hot liquid will spray out and cause burns3. Do not pour cold water on the cylinder block and cylinder head of the diesel engine. This action is likely to cause the cylinder block of the Perkins diesel generator set to burst due to sudden cooling.4. Remove the engine load, let the engine run slowly from medium speed to low speed, and then increase the speed after the standby temperature drops to normal.5. If there is a lack of cooling water, distilled water, purified water and other soft water can be added to prevent the formation of scale and affect heat dissipation.
