Deep well submersible pump and long shaft deep well pump how to control

1 control features: groundwater as a water source of the water, usually deep well submersible pumps to take water. The smaller groundwater plant consists of a deep well pump and a regulating water tower (the "one well one tower"). The deep well pump sends the groundwater to the regulation water tower, the water tower head water from the water tower to the user, this water supply way commonly used in the small town water works or the small and medium-sized factory water supply. Large-scale groundwater plants need to pool the water from several deep-well pump houses (commonly known as "well groups"), which are transported from pressurized pumping stations to distribution networks, often in medium-sized urban waterworks or Large factory water supply.

Deep well pump according to the motor where the external points are ordinary deep well pump (the motor is located in the tube wellhead above) and submersible pumps (pumps and motors are located in the tube well below the surface) two. Ordinary deep well pump shaft is longer, the bearing is lubricated and cooled by itself water flow. When the motor is started, the bearing is water-free, so the bearing pre-charging lubricating cooling water ("pre-run") is required before starting the water pump.

In the product manual often stressed "pre-run", and in actual operation, only the first pump or deep well pump after long-term use and then start, or the well water level is low when the pre-runner. General well water level is high, the well is very moist, the bearing clearance water is not easy to volatilize, so the general deep well pump without pre-run water to start to simplify the control wiring.

2, a well of a deep well pump motor control wiring: a well of a well pump water supply tower, according to adjust the water level of the water tower for automatic control, low water level automatically open pump, high water level automatically stop the pump. Water level control components are generally used GSK reed type bit controller or YX-150 electric contact pressure gauge (0 ~ 0.1MPa range, installed in the tank 2 ~ 3m height is appropriate).

3 well group control: deep well pump well group, the distance between wells is generally 300 ~ 800m, deep well pump motor capacity of about 10 ~ 100kW, the general deep well by a dedicated transformer power supply, using a transformer on a motor power distribution. Deep well pump well groups are generally centralized control in the control room.
