Wells will be dry during operation of the deep well pump. Drilling is a deep wells himself or manufacture by an acquaintance. Learn more at: Blimi Marcus. The actually planned depth could not be reached but with sufficient water level due to unexpected events. ZB. Is a big stone / boulders in the way after for down, or a very hard soil, z.B.Lehm, tone you no come through. Thus, the water supply to the filter of the fountain is too little.
Depending on the size / Leistug of the pump the water level slowly falls away and the pump runs dry. She can destroy the pump. The pump motor is no longer cooling the wheels/hydraulic) run dry, hot. eful source of information. This burns the motor winding and the Laufrader(Kunststoff) of the pump will be destroyed. Solution: Try the well bore at a different location. This is not possible, there are electronic or mechanical devices that prevent dry running.
1 Float switch (mechanical, electrical contact) this is fixed so that the off position to the the pump switches off lowest possible water level. The starting point must be selected so that the float switch is also sure turn. Problem: The diameter of the well is too small. The float switch can not move freely. The maximum attainable height of water level changes, for example Trockenheit(kein Regen).As a result, not the maximum achievable water level in the well is used. 2. Elektronicher pressure switch monitors the pressure / flow of the pump with dry-running protection of this. During normal operation, this switches off the power supply to the pump with closed sampling after a few seconds. If the collection is opened again, the pump restarts. But he falls fountain in the well and the pump, can deliver more water, the electronics switches off after a few seconds the pump and Ihen displays this error. Problem: This error message must then hand acknowledged / be unlocked.The pump is so not automatically switched on again. 3. electronic dry run well monitoring this electronic device has a probe with 2 separate Siften made of stainless steel. The probe with a plug of the unit is connected via 2 wires in the cable. The probe is positioned as in the deep wells above the entrance of the water that the pump is always in the water.If there is no water touched the 2 pins in the probe, the pump is automatically switched off. The restart delay time can be set, in minute increments from 1 minute to 99 minutes delayed! After a power outage, the timer restarts and switches the pump on again automatically after the eigestellten delay. No pressing the reset switch necessary. The device still has the possibility to cancel the delay time immediately with a button. Suitable for the connection to a heat pump. This device can be used for other tasks. Monitoring of water levels, E.g. pond must be installed Additionally a Relais/Schutz(Umkehrfunktion) between the unit and pump. Problem: If the well water strong iron sulphate,- or especially Mineral stop is, a film may be on the housing out of the pins a strong water film formed, which veandert the off or power-on behavior. A time-dependent control or cleaning the probe prevents this problem.
