Ultra-efficient motors: Three-phase brushless motor, smooth operation, high efficiency, long life, industrial-grade pumps.

Pump impeller: anti sediment, the unique design of attempts to prevent the transfer.

Frequency vector: low noise, low power consumption, can be started at low voltage and low temperature conditions, especially for high-power solar pump 4KW above.

MPPT tracking: The maximum power point tracking (Maximum PowerPoint Tracking).

Remarks:

2015 newest solar photovoltaic three-phase direct drive 3SP / 4SP / 5SP / 6SP / 7SP pumps, Germany INFINEON IGBT inverter module, three-phase direct drive frequency energy MPPT tracking solar photovoltaic pumps, used in the harsh conditions of high water and a big lift flow irrigation.

water pump for agriculture

ing parametres of this solar water pump for agriculture :

(1). Flow range10~600m3/h,

(2). Lift scope within 5~600m;

(3). Caliber scope 32~203mm,

(4). Temperature range-15~80° C.

2.Introduction of solar water pump for agriculture:

The solar water pump for agriculture is the high-tech production use the nature energy,saving time ,saving energy,saving labor.

There are two types solar system,DC series and AC series. About the DC water pump, It can direct connect PV panel.The AC solar water pump need connect with Inverter transfer power,then connect PV panel.The different power with different PV modules.

3.Use Conditions of 10T Sola Water Pump for Agriculture:

(1). 380 V bias voltage does not exceed -5% and 50 HZ frequency, and the deviation is not more than -1% of the three-phase power supply.

(2). Electrical cavity must fill water.

(3). The first-class pump impeller should at least go into the dynamic water level 2 m below surface. Static pump unit immersed under water shall not be greater than 70 m.

(4). Electrical from the bottom of the bottom of the well shall be not less than 3 m.

(5). The water temperature no higher than 20 ° C, QJR-temperature hot water pump up to 80 ° C.

(6). Water and sand content (by mass) of not more than 0.01%.

(7). Water PH 6.5-8.5.

(8). The hydrogen sulfide in water content is not more than 1.5 mg / L.

(9). Water should ensure continued operation of the pump needs.

4.Structure Feature of Solar Water Pump for Agriculture:

(1). pump: The pump is installed on the upper part of the pump units.It's centrifugal and has water lubricated

a. bearing mounted with the motor shaft by a joint.

b. There is a check valve on top of the pump which could prevent rapaid inverse rotation from backword flow.

c. The pump unit should be immersed below the dynamic water lever when in using.

(2). motor: The motor is installed under the pump.

a. It is a water filled in hermatical structure.The stator windings are water-tight and PE insulating and multi-layers are covered with nylon.

b. The motor bearing is water-lubricated.The inner motor contains clean water to cool the water body and the bearing.

c. The rubber diaphgram adjusts the pressure change caused when temperature rises.

d. There is a sand resistance system in the upper part of the motor.
