Why use the deep well pump to pre-water?

In the deep well water pump shaft along the bearing points are equipped with plastic bearings and rubber bearing like bracket, with support from it, it cat to water lubrication. In order to facilitate the start and reduce the friction between the shaft and the rubber bearing, in the start before the use of water lubrication. Such as the absence of water lubrication, such as rubber bearings and transmission shaft between the dry friction, heat deterioration, resulting in difficult starting or starting power increases, serious, there will be axle accident, the connecting parts loose and damaged.
     Pre-lubricated bearings like the use of non-sediment-free water without oil. Can pot or poke from the pump irrigation mouth filling, add the amount of water from the static depth of the water level, water pipe thickness, deep well pump speed and other factors. When the water level of 50-100 meters, the irrigation should not be less than 60-100 kg until the deep well pump water to stop irrigation. It is advisable to pre-lubricate with dilute soapy water prior to initial commissioning or long-term pump shutdown to improve lubrication performance.
