We are using anything, hope it is energy saving, but also hope it can reduce the use of loss and extend the service life. Xiaobian now talk about the energy-saving centrifugal pump and what are the ways? Centrifugal pump First, to improve the efficiency of centrifugal pumps The first step in the selection of centrifugal pumps more suppliers compared to the selection of programs, considering the premise of cost-effective as far as possible the selection of programs with high efficiency; the second step, a certain number of professionals stationed Produce in the factory, supervise the manufacturing quality of the key components that affect the pump efficiency, such as impeller, pump body, pump cover and deflector (vertical long axis pump), especially on the wing shape, water outlet angle, Indexing, the shape of the runner, finish and other quality control, so that the delivery of the product under the current production conditions of high efficiency products; the third step in the production site installation and commissioning process, to ensure that the solid foundation of the pump , And drive machine in good, before and after the valve switch flexible, reasonable pipeline layout, field control safe and feasible, all running monitoring instruments complete and accurate to ensure that the pump running process can be real-time monitoring; The fourth step is the long-term operation of the pump Should pay attention to the equipment inspection, found that abnormal circumstances immediately reflect the report, in the normal minor repair, overhaul cycle, the vulnerable parts should be checked replacement, Efficient and safe operation of long-term certificates pump. Second, optimize the existing pump By adjusting the impeller diameter and pump speed, the pump flow head and shaft power will have an impact, but has no effect on the efficiency curve, so that the pump can work in the high-efficiency zone. The above adjustment flow head is a certain range of limits, if the conditions change too much, the original pump may have to consider the modified. Outdoor air supply pipe to be considered waterproof leakproof measures, outdoor installation side of the air supply pipe units to be set to a certain degree of slope, roof installation unit outdoor air supply pipe must also be waterproof. The longer pipe is designed as multi-section air duct with different specifications according to the air volume. The pipe is connected by a variable-diameter pipe. The adjustable pipe should not be set too much. Generally, the whole system does not exceed four and the length of the variable-diameter pipe is ≥2 (Dd). Air supply pipe and air conditioner connection at the application of soft pipe, outdoor air supply pipe should be designed to keep warm, indoor generally do not need insulation. Circulating water pump with a continuous water tank out of the water and through the water distribution system evenly sprayed on the evaporation filter layer, the outdoor hot air into the evaporation medium, the evaporation medium CELdek (special materials honeycomb filter layer, So that the cooling effect is more satisfactory, Sweden's high-tech patent products) fully heat exchange with water, add water to evaporate heat cooling and cool, clean air from the low-noise fan pressurized into the room, the indoor hot air discharged to Outdoor, so as to achieve the purpose of indoor cooling.
