Photovoltaic water pumps, also known as solar water pumps, are often used in remote areas where there is no electricity or electricity, and use highly accessible and inexhaustible solar energy to achieve high economical and reliable water supply. Photovoltaic water pumps are fully automatic, sunrise and sunset, without personnel supervision, and the maintenance workload can be reduced to the minimum. It is an ideal green energy high-tech product integrating economy, reliability and environmental protection benefits.
Photovoltaic water pump systems use solar cells to convert solar energy directly into electrical energy, and then drive various types of motors to drive water pumps to pump water from deep wells, rivers, rivers, lakes, and ponds. It has many advantages, such as noiseless, fully automatic (sunrise and sunset, stop), high reliability, good adaptability of water supply and evaporation ("big drought, it is dry") and many other advantages. As the photovoltaic water pump system is technically a relatively typical "optical, mechanical, and electrical integration" system, it involves the collection, conversion of solar energy and the latest technologies in power electronics, motors, water machines, and computer control. Therefore, many countries have been listed as the priority for the development of high technology and further development. Many countries in the Middle East and Africa are also looking forward to relying on new technologies such as solar water pump, water saving micro-irrigation, modern agriculture, etc. The area transformed the homeland into an oasis.
Photovoltaic pump types:
1, brushed DC photovoltaic water pump
When the pump works, the coil and commutator rotate, and the magnetic steel and carbon brush do not turn. The alternation of coil current direction is accomplished by the commutator and the brush that the motor rotates. As long as the motor rotates, the carbon brush will wear out. When the computer water pump runs to a certain time, the carbon brush wear gap becomes larger and the sound will increase. After a few hundred hours of continuous operation, the carbon brush cannot play the role of reversing.
Advantages: low prices.
2. Brushless motor type photovoltaic pump
The motor type brushless DC water pump is composed of a brushless DC motor and an impeller. The shaft of the motor is connected with the impeller. There is a gap between the stator and the rotor of the water pump. Water will penetrate into the motor for a long time and the motor will burn out easily.
Advantages: Brushless DC motor has been standardized, there are a large number of specialized manufacturers to produce, the cost is relatively low, high efficiency.
3, brushless DC magnetic drive photovoltaic pump
The brushless DC water pump adopts electronic component commutation and does not need to use carbon brushes for commutation. It adopts high-performance wear-resistant ceramic shafts and ceramic bushings. The shaft sleeve is integrated with the magnets through injection molding to avoid wear and therefore brushless DC magnetic force. The life of the pump has been greatly enhanced. The stator part and the rotor part of the magnetic isolation pump are completely isolated. The stator and the circuit board part are encapsulated with epoxy resin, 100% waterproof. The rotor part uses permanent magnets. The pump body is made of environmentally friendly materials, low noise, small size, and performance. stable. The stator windings can be used to adjust various desired parameters, allowing wide voltage operation.
Advantages: Long life, low noise up to 35dB, can be used for hot water circulation. The stator and circuit board part of the motor are encapsulated with epoxy resin and completely isolated from the rotor. It can be installed underwater and completely waterproof. The axis of the pump adopts high-performance ceramic shaft, which has high precision and good shock resistance.

Matting Agent For Acrylic Coating
Silica is often used as a Matting Agent in acrylic coatings due to its ability to scatter light and provide a non-glossy, dull finish. This results in a more subtle, less reflective surface.
The silica can be in the form of colloidal silica or Fumed Silica. Colloidal silica is typically a fine, stable dispersion of silica particles in water or an organic solvent. Fumed silica, on the other hand, is produced by the high-temperature reaction of silane or siloxane vapors with oxygen, resulting in ultrafine, spherical particles.
When used in acrylic coatings, these silica particles are dispersed throughout the coating film. As light hits the surface, it is scattered in multiple directions due to the irregular shape and size of the silica particles. This scattering effect diminishes the intensity of reflected light, leading to a matte appearance.
In addition to providing a matting effect, silica can also enhance the physical properties of the coating, such as improving the film's hardness, adhesion, and abrasion resistance. It may also help to stabilize the formulation and improve the flow and leveling properties of the coating.
It's important to note that the amount and type of silica used can significantly affect the final appearance and performance of the coating. The particle size, surface area, and dispersibility of the silica will all play a role in determining the desired level of matting and the overall characteristics of the finished product.
