; Recently, Beijing Puquan Technology Co., Ltd. announced in the China Science and Technology Hall that an epoch-making invention on earth's ecological construction, agriculture and forestry irrigation, family's flower-growing and even water-saving and energy-saving - no energy-saving pump came out. Shen Guofang, vice president of China Academy of Engineering and forestry expert, commented: This is a good technology to benefit the country and benefit the people. Energy-saving mini-pumps can be used at very low cost to control any trace amount of water without consuming any energy. This will have a significant impact on the development of the world's ecological afforestation and even on saving water and energy. At the same time, the company launched a grand relying on non-energy-consuming pump (also known as universal spring pump, head control) technology developed and produced new products - Spring automatic watering treasure. It can greatly change the way people spend their flowers: the company staff do not have to worry about how much to water, family members do not need to worry about long-term unaccompanied travel. And the pump does not connect any energy, long-term use of safe and reliable Patent inventor, general manager of Beijing Puquan Technology Co., Ltd. Zhu Jun pointed out that no energy pump is based on the most advanced non-consumption water control theory as a guide, the use of related substances in Micron and nano-structure shown in the characteristics of the realization of the automatic, energy-saving, automatic suction and discharge of micro water control device. The key to the size of a pencil head or a bottle cap is that the universal spring pump utilizes the principle of "capillary-force natural control of the water and long-term, stable, fully automatic irrigation without the need for any energy" As we all know, a large number of pores in the soil capillary force; Puquan control head is also made of special materials capillary capillary force formed by the strong, to achieve automatic control of the water. This capillary force is very strong, even if the formation of negative pressure (below the liquid level head) Puquan control head can also be automatically pumped into the soil water. Even more amazing is that the universal spring technology to take advantage of this natural energy to achieve the micro-level automatic water treatment functions, thus ensuring the long-term stability of the capillary work; but also can be made according to the characteristics of plants, with a variety of special effects Active water. The water supply can be set according to the water demand of plants. Control head like a "perpetual motion machine," the source of power is the soil water demand, as long as the soil moisture does not reach saturation, capillary force will always exist, universal spring head will also work 24/7, its role is quite In a non-energy pump. Puquan irrigation technology from the invention of the capillary control water law Mr. Zhu Jun. This technology is also of great significance to improving the ecological barren hills afforestation. & Quanquan automatic watering treasure in use when there are several aspects of noteworthy: the capillary end of the water must be in contact with the soil; the end of the water from the plant closer to the root is more conducive to water use; fertilizer, please use Puquan special fertilizer to Anti-spring pump plug. On the other hand, Quanquan automatic watering treasure long life, use up to standard tap water life of up to three months to more than six months time.
The Sight Glass protect the refrigeration system and provide an important indication of any problem involving the refrigerant, moisture, or contamination in the system.
The function of the sight glass is to observe the liquid level of the refrigerant and detect the presence of moisture in the back end of the dry filter in the system. In a system with an Expansion Valve, a sight glass is usually fitted in the liquid line immediately after the filter drier. But In theory, the sight glass can be fitted at any desired location on the discharge line. However, placing the sight glass close to the expansion valve is especially advisable.
