Environment |
Each vacuum pump requires independent water pipes and an independent control box; Requires a circulating water pump, cooling tower, etc., to continuously replenish cooling water; In summer, the working liquid is in a high-temperature state for a long time, and the workshop is filled with water mist; accelerating the corrosion rate of the workshop's internal iron frames, various metal equipment, and metal steel beams; In the face of stringent environmental protection requirements, additional wastewater treatment equipment needs to be built. |
Highly integrated and highly intelligent, the machine front end is directly connected to the vacuum pipe and the power cord can be started and run, without the need for a foundation or other equipment. Under special operating conditions, additional pre-filtration equipment is required. |
Mechanical Efficiency |
General efficiency is around 30%; The water ring vacuum pump calibration is based on a 15℃ water temperature and 100% relative humidity intake, with the maximum pumping speed. Generally, when the cooling water temperature is higher than 15℃, the pumping speed is only 60-80% of the calibrated value. |
General efficiency is around 30%; Energy saving rate can reach 25%-50%.
