Power: 10kw single-phase: 230V
Flow: 0.06m3 / s Head: 25-60m
In the water-rich region is home to small-scale hydroelectric power of choice, because it sends an electric 230V / 400v does not require batteries and inverters, low cost, voltage stability. Such generators are used oblique Direct hit turbine units ready phase AC-excited synchronous generator thereof. Small size, light weight, simple structure, reliable operation, easy installation, etc., the most suitable to have isolated mountain farmers minute water resources to solve power plant lighting, television, etc. electricity. Turbine and generator have been strengthened to deal, reliable, stable performance, women and children may be operating characteristics, for farmers since the purchase, self, self-management, self-use. Users only need to be able to supply less investment to add to your family happiness and joy.
“Ramp-machine” adopts new inclined tube, nozzle, with large and small caliber, improve the efficiency of the turbine. Is provided between the motor and the separation turbine bearing section, adapted to withstand increased radial tapered roller bearings; refueling, water, greatly enhance the life of the unit, eliminating the commonOblique attack aircraftThe main disadvantages, to achievehigh quality.
10kw brush rotor excitation [copper wire around the rotor is] the automatic exchange regulator hydropower generating units [without unloading another load.
Ramp-type turbine generator units belonging to traffic generators of small high head, head range is generally applicable 5-70Meter. Its working principle is: the jet from the nozzle is not out tangentially, but along the plane of rotation of the wheel in a direction at an angle from the side of the wheel into the bucket, and then leave the other side bucket.
Our main production0.3KW-100KWSmall hydro-generating unit, install the following picture:
1, Installation Requirements: turbine planar contact with the base bottom plane tight seamless, the contact surface is neither the tail water splash, without leaking outwardly.
2, Setup: After pouring the concrete has cured the base unit, the unit installation position, and then sequentially watering. Measuring the level of the scale must be horizontal when the unit is installed, to ensure that the unit is fixed in a horizontal position. Horizon unit and plugging gaps with cement, does not allow water leakage. After the installation unit, then a check and hand turn rotates the turbine shaft, such as flexible and movable, even if the unit is installed.
3, Installation duct basic requirements: The pipe diameter pipe unit for later required, can reduce the high drop pipe diameter. Pipeline straight to minimize bending, pipeline and horizontal angle of not less than25Degrees, or growth pipe, the head loss is large, resulting in insufficient power generation and other consequences, installed in the front wall of the pool water inlet pipe with the flare if the most, from the bottom along which the plane is not less than0.2M, the inner diameter of the joint should be equal, in order to reduce head loss, should be minimized linker.
4, Pipe installation: micro hydro plurality flange welded steel pipe, be sure to let timing flange mounting pads, so as to reduce the flow section, the union nuts Yaoan diagonal order progressively tighten.
5, Piers: water in the pipe joint and the turbine nozzle, the maximum pressure on the pipe, it is necessary to build a stone or concrete anchor block, a metal tube is fixed.
6, Buttress: a metal pipe by its own weight and water weight, easy bending deformation pipe is too long, it must be added in the middle buttress. Position is preferably disposed at the branch pipe joint of the duct.
1, Check the pipes and fittings for leaks. If you find there is leakage, should analyze the reasons for timely treatment.
2, Obstruction of dirt left behind when the pipeline installation, to be cleaned to ensure the water flow.
3, After checking the pipe to withstand pressure of the water, whether or inflection deformed, the support is solid. If the event is not a normal phenomenon, should be timely manner.
A valve mounted on the water pipe, close to that end of the unit, from the nozzle of about1M is directly attached to the nozzle or, as the case may be. Micro hydro valve diameter pipe diameter should be consistent, the choice of gate or ball must not use valves, since the choice of cut-off valve to reduce the flow section will affect turbine output.
Valve installation must pay attention to two points:
1, Runner tail axle centerline watercourse must remain in the same vertical line.
2, Flange pad to pad positive fastening bolt connection, so as to reduce possible head loss, but also to prevent leakage.
Room micro-turbine group of civilian houses can be built, the room should be ventilated to ensure the house and does not leak, not water seepage. An area size of the visual unit, the unit to the wall distance not less than0.8Meters, so convenient installation, maintenance and operation of the operation.
Check before test machine. After the micro-hydro installation before commissioning, it must be checked. Check the contents include a review of the quality of the installation, inspection of micro hydropower units and electrical systems and other aspects.
Inspection of the quality of the installation
1, Drains, water pipes should be no leakage, the intake should be free of obstructions fences, flexible valve should open and close;
2, Water pool water level to maintain the design level;
3, Gutters should Gaiyan;
Inspection of micro hydropower units and electrical systems
1, Open the control box entry generator cover, check brush and slip ring contact is good;
2, Each fastener should be no loose mechanical connections;
3, Wheel rotation should be flexible, without shaking, the same sound, each of the rotating parts should be added a little oil.
4, With reliable electrical connection, the total load does not exceed the electricity generator rated power. Or connected with a power transfer device equipped with a mechanical regulator device unit may temporarily take the load, but must transfer requires electrical wiring or mechanical regulator device securely sensitive.
Slowly open the floodgates turn on the water, promoting water wheel rotates, the generator voltage will slowly rise to the rated voltage. Note 🙁 users install valves must take the valve to a maximum position) if the amount exceeds the maximum power generation unit rated generating capacity20%Should be off a small amount of water, the amount transferred to the maximum rated power generating capacity105%To prevent the crew work long hours under overload state. Try again if power generation is less than the designed capacity, the mouth should be checked before the pool water flooded the adequacy of depth, with or without the cyclone, water conduit clogging, whether the unit running jamming and friction and so on, and troubleshoot problems.
First ends of each consumer load shed, gates opened, then close the shutter. Permanent magnet motor should be off the turbine sluice, and then opened the gates
