2. The excitation mode of gasoline-electricity welding unit and gasoline generator unit is different. It provides the more stable excitation power to the rotor through the excitation coil, so its power generation state does not have a voltage regulator. Gasoline power generation welding unit is mainly composed of motor stator, control panel, rectifier and reactor. Its circuit includes a power generation system, an electric welding system, and an energy receiving system.
(1) The basic principle of the power generation state: The excitation power is supplied from the excitation coil to the fixed rotor through the rotation of the gasoline engine, and at the same time, the 220V power generation coil in the stator rotor generates current to supply power to the electrical appliance.
(2) Basic principle of power generation state: The excitation power is supplied from the excitation coil to the stator and rotor by the gasoline Yang rotation, and at the same time the 45V (6 groups) power generation coils in the fixed rotor generate current to supply power to the rectifier bridge, through the rectified 28V. DC power is provided by the reactor draw control panel to provide power for welding.
No current output:
1. The excitation coil does not generate electricity or the excitation coil rectifier bridge burns out. Measure the voltage across the brush (DC18V).
2. Burnout of the power coil or carbon wear is not in contact. Replacement processing.
Low output voltage:
1, welding, power conversion switch did not fit in place. Adjust the switch cable.
2, the frequency is too low. Adjust the speed control bolt of throttle operation handle and adjust the frequency to 53-53.5Hz.
Low welding current:
1. The gasoline engine's power is reduced or the speed is decreased. Observe that the gasoline engine shakes when welding.
2. The diode of the rectifier bridge is burned out. Check that the diode of the rectifier bridge has scorch marks.
3, control panel burn rectifier or current regulator damage, check and repair.
Agricultural grade phosphate refers to a type of phosphate fertilizer that is specifically formulated for use in agriculture. Phosphate is an essential nutrient for plant growth and is necessary for various biological processes, such as photosynthesis, energy transfer, and cell division.
Agricultural grade phosphate is typically derived from phosphate rock, which is a naturally occurring mineral that contains high levels of phosphorus. This rock is processed to extract the phosphorus and convert it into a form that is readily available for plants to absorb.
The main benefit of using agricultural grade phosphate is that it helps to replenish phosphorus levels in the soil, which can become depleted over time due to plant uptake and erosion. Phosphorus is an essential nutrient for crop production, and a deficiency can lead to reduced yields and poor plant health.
Agricultural grade phosphate is available in various forms, including granules, powders, and liquids. It can be applied to the soil through methods such as broadcasting, banding, or fertigation. The application rate and timing will depend on the specific crop, soil conditions, and nutrient requirements.
It is important to note that the use of agricultural grade phosphate should be based on soil testing and nutrient management planning to ensure proper application and avoid overuse, which can lead to environmental pollution. Additionally, some countries have regulations in place regarding the use of phosphate fertilizers to protect water quality and prevent excessive nutrient runoff.
Overall, agricultural grade phosphate is a valuable tool for farmers to improve soil fertility and promote healthy plant growth.
