Description

Permanent magnet generator special for irrigation

Technical Field

The invention belongs to the technical field of vacuumizing equipment, and particularly relates to a permanent magnet generator special for irrigation.

Background

The generator is mechanical equipment which converts other forms of energy into electric energy, is driven by a water turbine, a steam turbine, a diesel engine or other power machines, converts energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits the mechanical energy to the generator, and then the generator converts the mechanical energy into electric energy. In the current dc motor, an excitation method of generating a main pole magnetic field by a dc current is called current excitation; if permanent magnets are used instead of current excitation to produce the main pole field, such machines are referred to as permanent magnet motors.

Need supply power to the suction pump through the generator when irrigating, and permanent magnet motor long-time during operation, the permanent magnet heat production need in time cool down permanent magnet generator, and the special permanent magnet generator of irrigation who uses at present, install an individual drive's water-cooling structure to the generator, increased the consumption to in long-time working process, the cooling effect is also not stable enough, so need to irrigate special permanent magnet generator and upgrade the design, guarantee its job stabilization nature in the operation of irrigating.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a permanent magnet generator special for irrigation, which comprises a permanent magnet generator shell 1, wherein an outer pipe 2 is sleeved outside the permanent magnet generator shell 1, a metal partition plate 3 is welded between the outer pipe 2 and the permanent magnet generator shell 1, a water flow channel 4 is formed between the metal partition plates 3, two ends of the water flow channel 4 are sealed by an annular cover plate 5, a pipe joint 6 corresponding to the water flow channel 4 is arranged on the annular cover plate 5, the pipe joint 6 is communicated with a water storage tank 7 through a connecting pipe, and the two water storage tanks 7 are respectively communicated with an irrigation water pipe 9 and a water pumping pipe 10 through connecting flanges 8. Produce electric power and supply power to the suction pump at permanent magnet generator during operation, the drinking-water pipe carries the rivers passageway 4 between outer tube 2 and the permanent magnet generator shell 1 through water storage tank 7 with the river water of suction pump extraction, the heat on the permanent magnet generator shell 1 is taken away to the in-process of the inside flow of rivers passageway 4, thereby the generator carries out the water-cooling, irrigate the operation in 9 to the field at the irrigation water pipe through the other end, guarantee at the irrigation in-process, the water-cooling heat dissipation lasts the work, guarantee the stability of permanent magnet generator long-time work, the characteristic that the irrigation water flows has been utilized, carry out the water-cooling to the generator, it is stronger to the suitability of irrigating the operation.
