5KW Low Speed Electric Vehicle Range Extender
The range extender can be started by hand, but it cannot start?
New machine:
1. Disconnect the oil pipe from the carburetor to see if the oil is flowing properly and increase the idle speed slightly.
2. If there is no problem with the oil, check to see if the spark plug is burning.
3. If there is oil and fire but still no ignition, check reverse and forward rotation. (Press in the direction of the handle to rotate forward)
4. Then check if the air door is closed normally.
5.? Check if the measured voltage is too high. The 60 volt protection voltage is 68 volts, and the 72 volt protection voltage is 80 volts.
6. The carburetor should be cleaned after leaving it too long. Before use, add 5 ml of engine oil and read the instructions carefully.
Old machine:
1. Unscrew the spark plug and determine if there is a fire and carbon deposits.
2. Wipe the spark plug and install it. Start the extension cord. If it still doesn't catch fire, remove the spark plug and see if there is any oil on the spark plug. Otherwise, clean it. the carburetor or replace it. After cleaning, blow with an air gun.
3. Open the air filter cover and check whether the air door switch is normal.
4. Return to factory for repair.
Since the cruising range of low-speed four-wheel electric vehicles is still relatively limited and cannot fully meet the daily travel needs of the public, if you want to increase its cruising range , you can install an extended autonomy. Increase its cruising autonomy, increase its range of activities, meet the needss daily travel of the public and go back and forth freely, without more difficulty due to the lack of power halfway.
What is the reason why the high voltage box of the generator is not sparking? Is this related to AVR?
The solution to the problem that the generator generates light but has a neutral wire but no live wire is:
1 Connect the other two phase wires: the output end. of the generator is only connected to one phase wire and for one neutral line you can try to connect the other two phase lines, so that the output end of the generator is connected to three phase lines and one neutral line. This ensures that the generator output voltage waveform is complete and meets electrical safety standards.
2. Use an automatic voltage regulator: to ensure the stability and accuracy ofthe generator output voltage, an automatic voltage regulator can be used for adjustment. The automatic voltage regulator can automatically adjust the output voltage according to load changes and grid voltage fluctuations to ensure voltage stability and accuracy. At the same time, the automatic voltage regulator can also detect whether the wiring is correct, avoiding the problem of incorrect wiring.
What should I do if the gasoline generator fails to ignite?
a. Cathode ray tube support ignition maintenance.
Ignition of the cathode ray tube support is generally done at the focus level. The main reason for sparking inside the CRT holder is that the monitor is used in too humid an environment or has not been used for a long time. Since the focus stage voltage is very high, inFor 4 and 9 KV, the repair method is to turn off the power, remove the tube bracket from the back plate, use a knife or fine sandpaper to scrape off the rust on the tube pins. , then use pure alcohol to clean well. And remove the rust on the plastic inner wall of the pipe seat. Clean it with alcohol, then dry it with a hair dryer and reinstall it.
b. Sparks around the high pressure nozzle or high pressure cap of the CRT.
Sparking around the high pressure nozzle of the picture tube may be caused not only by humid environment, but also by loose contact or impurities between the high pressure nozzle of the picture tube and the conical glass. . To repair the high pressure nozzle and ignite it, you must first unload it. The method involves inserting a large, flat, wooden-handled knife into the high-pressure nozzle and touching it several times.times. Sometimes you may hear a discharge sound. . Then remove the high pressure cap and check the high pressure nozzle and high pressure circlip for rust and signs of sparking and dust buildup around them. If so, you can clean it as before and then dry it with a hairdryer. Pay attention to the temperature and duration to avoid local overheating of the display tube and bursting. Then apply a little butter evenly around the high pressure nozzle, then attach the high pressure cap.
c. The high voltage box and the focus potentiometer are turned on.
Turning on the high voltage box may cause the network to become blurry or have no network. If the high voltage box itself catches fire, the only option is to replace it with a new one. If the cable end of the high voltage box sparks, you can wipe it withpure alcohol.
If the focus potentiometer of the high voltage box ignites, you can turn off the power and adjust the focus potentiometer several times to see if the internal contact contact can be improved. Otherwise, it is best to replace it.
Advantages of high voltage generators:
With the same power, high voltage generators have high voltage and low current. Since the loss is proportional to the current, the current is small, the voltage loss, power loss and no-load loss are all small. The cross section of the coil winding is also proportional to the current. If the current is small, the cross section of the coil winding will be small, which can save winding materials. The current is small, the body can be reduced, and materials such as cast iron and iron core can be saved.
Checkboard if engine oil and gasoline are newly added. Otherwise, they have been added for more than three months and the oil and gasoline need to be drained and replaced. Engine oil and gasoline are only valid for three months. Oil and gasoline used for more than three months have lost their viscosity and are useless.
Check if the engine oil and generator gasoline are filled. Otherwise, the generator will not be able to turn on and start.
If the above is achieved, check if the spark plug lights. Otherwise, remove the spark plug, dip some gasoline in it and install it to see if the generator ignites. Ignition on and everything will be fine.
Detailed information:
When using a gasoline generator, please note:
1) Theory guides practice. Only by fully mastering the basic principles and basic structure of small gasoline engines can weWe carry out fault analysis and treatment, especially for different types of oil engines, specific analysis of specific models is required;
2) When an error occurs. Only by carrying out comprehensive and scientific analysis and judgment based on the scene can we guarantee that the fault is handled accurately, and we cannot handle the problem based on imagination or guesswork. so-called past experience. Gasoline engines often have oil lines, circuits and other parts appearing at the same time. Faults produce more complex fault phenomena. Sometimes similar phenomena occur at different fault points, causing certain troubleshooting difficulties.
By connecting and analyzing the fault phenomena observed on site, by imagining different possible causes of the failure and by analyzing and comparing them, the extent and localizationthe fault can be determined. Then from simple to complex, from the outside to the inside, first analyze the circuit then the oil circuit, then calibrate the ignition time, check the order of gas distribution, and compress the fault until 'at a certain point
3) Develop good habits, carry out necessary inspections before starting the machine and carry out regular inspections during machine operation to try to avoid sudden breakdowns
4) Strictly carry out technical maintenance; all levels on the oil machine to ensure that the oil is in good working condition to avoid sudden breakdowns and major accidents.
