in areas rich in water resources, small hydro generator is the preferred power source for families, because it emits 220V electricity, does not need storage battery and inverter, and has low cost and stable voltage. This generator is a inclined jet hydroturbine unit composed of single-phase alternator directly connected permanent magnet synchronous outfit. It has the characteristics of small volume, light weight, simple structure, reliable operation, convenient installation and use, etc. It is most suitable for mountain farmers with sporadic small water power resources to solve the generating set of lighting, television and other electricity. Both water turbine and Dynamo have been treated by strengthening technology. The quality is reliable, the performance is stable, and women and children are operational. It is suitable for farmers to purchase, build, manage and use themselves. Users only need less investment to add happiness and joy to your family.
“Inclined hammer” Adopts New Inclined Tube and nozzle, equipped with large and small diameter, which improves the efficiency of hydraulic turbine. Separating support section is arranged between the motor and the hydraulic turbine, adding a tapered roller bearing which is suitable to bear the radial direction; It can be oiled and waterproof, which greatly improves the service life of the unit and avoids the main disadvantage of ordinary inclined machine, to achieve high quality.

Inclined type small hydro generator

the hydraulic turbine is composed of simple spoon blades, which consists of the shell, nozzle, impeller and generator. Its design is extremely simple. When the high-speed water flow from the nozzle to the blade, the blade rotates at high speed, so as to drive the generator to generate electricity. Because of its simplicity, it has the characteristics of small volume, light weight, simple structure, reliable operation, easy installation and use, etc., and it is most suitable for mountain farmers with sporadic small water power resources to solve lighting, TV and other electricity generating set.

Inclined type water turbine-generator units belongs to high-water bowl head low-flow generator set, generally applicable water bowl head range is 5-70m. Its working principle: the jet coming out from the nozzle is not along the tangential direction, but along the direction which forms an angle with the rotating plane of the Reel, and enters the bucket blade from one side of the Reel, then leave the bucket leaves from reverse side.

Our main products0.3KW-100KWsmall hydro-generator set, the installation picture is as follows:

installation &. instruction

1, installation requirements: the hydraulic turbine bottom surface shall be in strict and seamless contact with the fundamental plane, and the contact surface shall not splash the tail water or leak outward.

2, installation Procedures: After the basis of the unit which needs watering concrete is cured, install the unit in place, and then water in turn. During unit installation, the level must be measured with a level ruler to ensure that the unit is fixed in a horizontal position. The gap between the unit and the region is Grout off, and no water leakage is allowed. After the unit is installed, check it again and turn the Reel shaft of the hydraulic turbine by hand. If the unit is flexible, the unit is installed.

3, basic requirements for the installation of pipelines: purchase pipelines according to the diameter of the pipeline required by the unit. High drop can reduce the diameter of the pipeline. The pipe should be straight, and the curve should be reduced as far as possible, and the angle between the pipe and the horizontal should not be less 25 otherwise, the increase of pipelines will result in great loss of water bowl head and low power generation. The water inlet of the water diversion pipe installed in the front pool wall is the most important one to use flared tube, and its lower edge is not less than the plane from the bottom of the pool 0.2 rice, the inner diameter of the joint should be equal, in order to reduce the loss of water bowl head, the joint should be reduced as much as possible.

4, the installation of steel pipes: the micro hydropower mostly uses steel pipes with flanges. When installing, the flange gasket must be placed upright, so as not to reduce the cross section of water, and the joint nut of the pipe should be tightened gradually in the diagonal order.

5, town Pier: at the joint of water diversion pipe and turbine nozzle, the pressure on the pipe is the largest, so a town pier must be built with stone or concrete to fix the metal pipe.

6, buttress: because of the weight of the metal pipe and the water, the pipe is easy to flexural deformation when it is too long, and the buttress must be added in the middle. The location of the branch sewer is best set at the connector of the pipe.

Post-installation check

1, check the pipe and connector for leakage. If any seepage is found, the cause should be analyzed and dealt with in time.

2, clean the filth left in the pipeline when installing to ensure smooth water flow.

3, check whether the pipe is bent or deformed after bearing the pressure of water, and whether the support is firm. If you encounter abnormal phenomena, you should deal with them in time.

The installation of the valve

the valve is installed on the diversion pipe, close to the end of the unit and away from the nozzle1 meters or are directly installed on the nozzle, depending on the specific situation. The diameter of the valve of the micro-hydropower should be the same as the diameter of the water pipe, and the gate valve or ball valve can be selected. The stop valve must not be used, because the selection of the stop valve will reduce the water section and affect the output of the turbine.

The installation of the valve must pay attention to two points:

1, the axis of the water turbine Reel and the center line of the tail waterway must remain on the same plumb line.

2, flange gasket should be placed right and the bolt connection fastened, so as to reduce the loss of water bowl head and prevent leakage.

The equipment room

the engine room of the micro hydraulic turbine unit can be built in accordance with the civil buildings, and the room should be guaranteed to be ventilated inside, watertight and watertight. Its area can be determined according to the size of the unit, and the distance from the wall of the unit should not be less 0.8 meters to make installation, maintenance and operation convenient.

Debugging

check before commissioning. After the installation of the micro-hydropower, the inspection must be carried out before the trial operation. The contents of the inspection include the inspection of installation quality, the inspection of hydropower units and electrical systems, etc.

Inspection of installation quality

1, there should be no water leakage in the canal and diversion pipe, and there should be no sundries blocking in the fence of water inlet, and the valve should be opened and closed flexibly;

2, keep the water level of the pool to the designed water level;

3, the drainage ditch should be covered tightly;

inspection of micro-hydropower units and electrical systems

1, open the cover of generator control box, and check whether the contact between brush and sliding bracelet is good;

2, all mechanical connecting fasteners should not be loose;

3, the rotation of the Reel should be flexible without shaking or no foreign.

4, the electrical wiring is reliable, and the total power load does not exceed the rated power of the generator set. The unit connected with the electrical regulator or the mechanical voltage regulator device can temporarily not connect the load, but it must require the electrical regulator to be connected firmly or the mechanical voltage regulator device to be sensitive.

Commissioning

slowly open the gate to drain the water, the water flow pushes the Reel to rotate, and the generator voltage will slowly rise to the rated voltage. Note: (users who install valves must open the valve to the maximum position) if the maximum power generation exceeds the rated power generation of the unit20%, should turn off a small amount of water, and adjust the maximum power generation to the rated power generation105%just in case the machine leader works in an overloaded state. If the generating capacity is less than the design capacity, it is necessary to check whether the flooding depth of the front pool is enough, whether there is cyclonic entry, whether there is blockage in the Catchwater, whether there is blocking and friction in the unit operation, etc, and try again after troubleshooting the problem.

Parking

remove the load of each power terminal first, open the electric gate, and then close the gate. Permanent magnet motor should first turn off the water turbine gate, and then open the electric gate
