1. Improve the efficiency of centrifugal pumps
The first step is to compare the selection schemes of each supplier in the selection process, and try to use the high efficiency scheme on the premise of considering the cost performance;
In the second step, a certain number of professionals are stationed in the factory to supervise the manufacturing quality of key components such as impellers, pump bodies, pump covers, and deflectors (vertical long-axis pumps) that affect pump efficiency, especially for impellers. The quality of the wing shape, water angle, blade index, runner shape, finish, etc. are controlled so that the delivered product is a highly efficient product under current production conditions;
The third step, in the installation and commissioning process of the production site, to ensure that the foundation of the pump is reliable, the alignment with the drive machine is good, the front and rear valve switches are flexible, the pipeline layout design is reasonable, the site control is safe and feasible, and the operation monitoring instruments are complete and accurate. The operation process of the pump can be monitored in real time. The fourth step is to pay attention to the inspection of the equipment during the long-term operation of the pump, and to report the abnormal situation immediately. In the normal minor repair and overhaul cycle, the consumables should be handled. Check and replace to ensure long-term efficient and safe operation of the pump.
2. Optimize existing pumps
By adjusting the impeller diameter and the pump speed, it will affect the pump's flow head and shaft power, but has no effect on the efficiency curve, allowing the pump to operate in the high efficiency zone. The above adjustment of the flow head has a certain range of restrictions, if the working conditions change too much, the original pump may have to consider the modification.
The outdoor air supply pipe should be protected against water and leakage. The outdoor air supply pipe of the side wall installation unit must be set to a certain degree of slope. The outdoor air supply pipe of the roof installation unit must also be waterproof. Longer pipes are designed into a plurality of ducts of different specifications according to the different air volume. The connecting pipes are connected by variable diameter pipes. The setting of the reducing pipe should not be too much. Generally, the whole system does not exceed four, and the length of the reducing pipe is ≥ 2 (D-d) to determine. The soft connecting pipe is applied to the connection between the air supply duct and the air conditioner, and the outdoor air supply duct should be designed to be insulated, and the indoor generally does not need to be insulated.
The circulating water pump is used to continuously pump out the water in the water tank and spray it evenly on the evaporation filter layer through the water distribution system. The outdoor hot air enters the evaporation and cooling medium, and the evaporation filter medium CELdek (the special material honeycomb filter layer, To make the cooling effect more ideal, Sweden's high-tech patented product) fully exchange heat with water, add water to evaporate heat and cool down the cool, clean air is sent into the room by low-noise fan, so that the indoor hot air is discharged Outdoor, thus achieving the purpose of indoor cooling.
