Oil pump and water pump which is based on your environment and the use of pumping medium to decide, if the number of mining underground water tower water drainage points, some river water, lake water can choose QY oil immersed submersible pump,
For farmland irrigation, sprinkler irrigation, wells for water, living water, industrial and civil building water supply and drainage system, water diversion, and in mountainous and hilly areas of low-lying areas and drainage occasions can choose QS water pump.
Motor cooling water submersible pump is filled with water, and motor cooling oil immersed submersible pump is filled with lubricating oil, the two have cooling ability is very strong, and have strong ability of waterproof. Two different main:
Types of electric coolant.
Oil immersed mechanical oil, and water use of water.
Impact on the environment.
If the water leakage will not cause pollution to the environment, oil immersed oil will cause pollution to the environment
Water can be used for drinking water applications, oil immersed is mainly used for agricultural irrigation, water supply, water fountains, flood control and drainage, municipal drainage construction etc..
The oil filled submersible pump with mechanical oil lubrication, the lubrication condition is better than water immersion, often long service life.
Chinese quality news network news, the first quarter of 2012, Shanxi Province Quality Supervision Bureau of Taiyuan, Lvliang area distribution unit of 22 batches of a small submersible pump and the 3 production enterprises of 3 batches of a small submersible pump a total of 25 batches of a small submersible pump quality supervision and spot checks, qualified 16 batches, sample pass rate 64%.
The spot checks found that the main quality problem is the existence of hidden dangers in the security measures, leading to the cable is too short, the pump efficiency and pump head can not meet the standard requirements. The Lishi District of Lvliang City Xin Wang QDX1.5-32-0.75 Motor Sales Department Distribution nominal Taizhou Dazheng pump industry limited production of single-phase submersible pump, the grounding, cable, pump leads to efficiency, the provisions of point flow and lift were not consistent with the standard requirements.
According to the provincial quality supervision of the products reflect the problems, the Shanxi Provincial Bureau of quality supervision requirements of quality supervision departments at all levels must be strictly in accordance with the relevant laws and regulations, the spirit of "fuyoufujiang, Dajiazhilie, consumer guide" principle, do a good job of product quality supervision and inspection work, postprocessing.
