1. Type D: Type D pump for the transport of water without solid particles, temperature slower than 80 degrees C of clean water or physical and chemical similar to clear water liquid, suitable for mining or urban water supply and drainage works.
Type D pump for delivery temperature of -20 c to 105 degrees C, no solid particles of corrosive liquid, can also be used as a second high-pressure boiler for water pump, pump import allowed pressure of 0.6MPa. The user can choose the material of the pump, seal form, structure of the pump and determine the capacity of the motor according to the name, concentration, pump import pressure, use temperature and so on.
The D-pump is used to transport oil and petroleum products with a temperature of -20 c to 105 degrees C, with a viscosity of less than 120 percent.
The D-pump is used to transport mine water and similar liquids containing a small amount of solid particles with a particle diameter of less than 0.5mm and a temperature of less than 80c.
Type D pump for the transport of non-solid particles, temperature below 105 degrees C of clean water, or physical and chemical similar to the liquid of clean water, suitable for medium, hot water-like medium and medium and low pressure boiler water supply or transport hot water and class.
有时候水泵乃至会被冻住住,今天来教您在冬季怎样对卧式多级泵进行保养?水泵停用后,要放尽水泵和管路内的剩水,并把外部泥土清洗洁净,避免上冻后积水结冰把泵体和水管胀裂。水泵的底阀、弯管等铸铁件,应当用钢丝刷把铁锈刷净,然后先涂上防锈漆后再涂上油漆,待枯燥后再放入机房或贮存室通风枯燥的当地保存。用皮带传动的,皮带卸下来后用温水清洗擦干后挂在枯燥、没有阳光直接照耀的当地,也不要存放在有油污、腐蚀物及烟雾的当地。不管在何种情况下,都不要使皮带沾上机油、柴油或汽油等油类物质,不要涂松香和其他粘性的物质。查看滚珠轴承,如内外套磨损、旷动、滚珠磨损或外表有斑点都要替换。对不需求替换的可用汽油或煤油将轴承清洗洁净。
