There are two wire generators on the ground brush for the inner iron, and the root wire generator is the outer iron. There are two wire generators on the insulation brush for the inner iron, and the root wire generator is the outer iron 2 fire method. Use the root wire to connect the armature terminal of the power generation port to the magnetic field terminal. The time should not be too long. Start the engine and run at medium speed. Use a screwdriver to set the fire between the armature terminal and the casing. If there is a strong spark, The generator is grounded inside, and vice versa. 3 Run the generator as a motor. Remove the generator belt first. Use the 抿 wire to connect the armature terminal to the magnetic field terminal. Otherwise, the positive pole of the battery is used for the positive pole, the pole is connected, the negative pole of the generator is connected to the casing of the generator, and the other pole of the battery. Instantly touch the generator armature terminal, such as the generator rotation, indicating that the generator is built-in iron; if the generator rotates slowly or does not rotate, it means that the different ground type generators of the outer iron 3 can be different The iron type regulators can be used with the inner iron generator to be used with the inner iron regulator; the outer iron generator can only be used with the smashing iron stern, and can not be mixed, otherwise the excitation winding is short-circuited. generator. Can generate electricity. If the accessories are not available and must be modified, the generators or regulators must be properly adapted to match each other. For example, if a certain car is originally used with an external iron generator and a regulator, if the regulator is damaged and the matching regulator is not found, the generator can be changed to the inner iron type, and then the appropriate one is selected. The inner iron regulator can be used or the generator can not be connected, and the appropriate domestic inner iron regulator can be used to change it to the outer iron. 1; the method of changing the iron generator to the inner iron Reconnect the end of the excitation winding to the grounding post to the grounding brush, and then connect the end of the original insulating carbon brush to the 汴 terminal, so that the magnetic winding is passed after the reconnection and before the reconnection. The current in the direction is not. Change, will not affect the generator power generation, the internal branch regulator is changed to the external iron method to adjust the balance of the internal iron regulator, such as the Jiefang brand car regulator, from the interceptor iron frame t In order to ground, and the 30 resistors are also removed from the armature wiring to ground.
The method of changing the inner iron to the outer iron is to connect the magnetic field of the generator, and the lead wire and the magnetic field line originally connected to the iron carbon brush are separately disassembled. Connect the magnetic field terminal to the lead wire, the insulating carbon brush, and connect the field line originally connected to the grounding iron brush to the magnetic field terminal. Note that the polarity of the positive and negative grounding of the generator has not been changed after the modification. The terminal still needs to be connected to the regulator armature terminal. Do not reverse the wire end. Otherwise, the generator will not be able to generate electricity. Check the generator motor test method of the grounding generator. The generator and power supply are connected, and the generator is used as the motor. Observe the operation, and measure the speed and current consumption to determine whether the generator has mechanical and electrical faults. During the test, the voltage of the battery should be the same as the rated voltage of the generator. The polarity of the grounding of the battery must be caused by the generator, otherwise the direction of the residual magnetism of the generator will change. When the normal generator is used as the motor, it should be operated in a balanced and noise-free manner. When the belt is at the end of the belt, it should be rotated clockwise. There should be no strong spark between the flow and the carbon brush. The speed and current consumption should be Including requirements, if the speed is low, the power consumption is large, indicating that the generator has mechanical failure, such as electricity, there is stuck in the bearing too tight; the bearing seat is twisted; the armature core and the magnetic pole are rubbed, etc. The power consumption is large, indicating that the power consumption of the excitation winding has a short circuit, and the power consumption is too small, indicating that the contact in the armature circuit is poor, such as insufficient pressure of the spring and the carbon brush oil brush spring. If the direction of rotation is incorrect, the connection between the two ends of the excitation winding is incorrect.
Starting speed test The so-called starting speed refers to power generation hunger under no-load and full load conditions. The minimum speed test when the rated current is issued can be performed on the electric test stand 1, or a small test stand can be made. The test bench has a variable speed motor and 30030 DC current. 050 DC voltage and 2.5230, variable resistance. During the test. Gradually increase the speed of the generator, and record the speed when the voltage rises to the rated value, that is, the idle speed = then increase the speed of the generator, close, close, and the trimming resistance, and the voltage reaches the rated value under full load. The speed of the time is the full load speed, and the test data should meet the technical requirements.
In the absence of the above test equipment, the fire test of the generator can be used to initially reflect the technical condition. The generator uses a wire to connect the armature and the magnetic field terminal. The root rope is wound around the pulley and wound in the direction of the generator rotation. The rope is pulled hard to rotate the generator in the direction of the gauge. At this time, the wire connected to the two terminals is Fire on the outer casing. If there is a strong spark, it means that the generator can generate electricity. Otherwise, it indicates that there is a fault. Responsible editor He Yusen
Skid steer loaders are also known as skid steer loaders, multi-purpose engineering vehicles, and multi-functional engineering machines. It is a wheeled special chassis device that realizes the steering of the vehicle by using the difference in line speed between the two sides. It is mainly used in occasions where the work site is small, the ground is undulating, and the work content changes frequently.
It is suitable for infrastructure construction, industrial applications, terminal loading and unloading, urban streets, houses, barns, barns, airport runways, etc., and can also be used as auxiliary equipment for large-scale construction machinery. There are two types of skid steer loaders: wheeled and tracked.
