Guangzhou-Puda Sports Equipment Installation Co., Ltd. is a collection of swimming pool water treatment, sauna spa equipment, marketing landscape water treatment, equipment and engineering products, related accessories and services in one of the new high-tech enterprises. The company uses the most advanced water treatment technology for the majority of a swimming pool, spa bath, landscape fountain pool, sauna, pool, and other projects to provide the most optimal configuration and high-quality equipment and related products. The general characteristics of the centrifugal pump (1) along the direction of the water flowing through the axial direction of the impeller is a centrifugal pump suction, perpendicular to the axial outflow pool pumps, i.e. inlet and outlet flow direction into each other 90 °. (2) due to the formation of a centrifugal pump impeller inlet by vacuum suction, and therefore must before starting the pump and filling water in the suction pipe to, or use vacuum pump to discharge air to form a vacuum, and the pump casing and suction pipe must be tightly sealed, not leak, or else do not form a vacuum, there is no water to suck. (3) can not be formed due to the impeller inlet absolute vacuum the pool pump parts, centrifugal highly absorbent and therefore can not be more than 10 meters swimming pool pump equipment, coupled with losses along the way water flows through the suction line to bring the actual permit installation height (pump axis from the inhalation height of the water surface) is much smaller than 10 m. Such as the installation is too high, no water absorption; In addition, because the mountain is lower than the atmospheric pressure is plain, so the same pumps in the mountains, especially in the high mountainous installation, the installation height should be reduced, otherwise it can not absorb Sheung Shui Jian Guangzhou Puda Sports Equipment Installation Co., Ltd. focuses pool / swimming pool equipment, swimming pool design, pool design and installation of a sauna, swimming pool engineering design and construction, landscape water treatment equipment, swimming pool circulating water filtration equipment and other services.

Frequency control to achieve constant pressure water supply pool pump selection, and with regulating valve to achieve constant pressure water supply compared to energy-saving effect is very significant (can be calculated depending on the circumstances). Its advantages are: 1, the starting balance, starting current limit within the rated current, thus avoiding the impact on the grid at the start; 2, the average pump speed is reduced, thereby prolonging the life of pumps and valves; 3 can eliminate water hammer effect starting and stopping; Generally speaking, when by a frequency control a motor, just so that you can match with the drive motor capacity and the actual motor capacity. When an inverter simultaneously control two motors, in principle, with the drive motor capacity should be equal to the sum of the two motor capacity. However, if at the time of peak load a lot of water, it can be considered appropriate to reduce the capacity of the drive, but it should be noted that there is sufficient capacity to supply the amount of speed than the difference between the two pumps.
