What is a solar water pump?

The solar water pumping system is a photovoltaic water pumping system that uses photovoltaic arrays to drive the water pump to work by the power generated by the photovoltaic array. The system is mainly composed of a photovoltaic array, a photovoltaic lift water inverter, and a water pump.

Solar water pump, also known as solar photovoltaic water pumping system, is an electro-mechanical integration system that has been rapidly developed in recent years. It utilizes the power generated by solar cells to drive DC, permanent magnet, and brushless by means of maximum power point tracking and transformation and control. , No-position sensor, fixed-rotor double-plastic motor or high-efficiency asynchronous motor or high-speed switch reluctance motor drives high-efficiency water pump to lift water from the depth of the ground to the ground for irrigation of farmland or human and animal consumption.

Solar water pumps are divided into two major series: DC pumps and AC pumps. Among them, the direct current water pump motor drive mode is divided into two major categories: a brushless DC motor and a permanent magnet synchronous motor.

Solar water pump use matters needing attention:

1. Prevent particles from entering

(1) Ferromagnetic impurities and particles are not allowed to enter the magnetic actuator and the bearing friction pair;

(2) To transport the easily crystallized or precipitated medium, rinse it in a timely manner (pump water into the pump chamber after stopping the pump, and discharge it clean after running for 1 minute) to ensure the service life of the sliding bearing;

(3) When transporting media containing solid particles, filter at the inlet of the pump tube.

2. Prevent demagnetization (DC pumps)

It should be operated under the specified temperature, and the medium temperature is forbidden to exceed the standard. A platinum resistance temperature sensor can be installed on the outer surface of the isolation sleeve of the magnetic pump to detect the temperature rise in the annular region so that the temperature can alarm or stop when the temperature exceeds the limit.

3 . Prevent dry friction

Minimize idle time.
