First, the vacuum pump can not start or start a large noise A. Possible causes: Motor supply voltage shortage; Motor phase loss of running; Pump for a long time useless cause corrosion; Pump sucked debris; Impeller drag distribution board. B. Remedy: Check the supply voltage is too low; Check the motor wiring are solid; If the pump for a long time useless rust can add some rust remover or open the pump cover artificially remove rust; Open the pump cover to remove debris; Adjust the impeller and the distribution board distance. Second, the vacuum pump is not enough A. Probable causes: inadequate power supply led to insufficient speed; insufficient water supply; gap between the impeller and the distribution plate is too large; mechanical seal damage leading to leakage leaks; impeller wear too much; . B. Remedy: Check the supply voltage is within the motor rated voltage range; increase the amount of water (must be controlled in the correct range, otherwise it will cause the motor overloaded fever British Branch valve); adjust the gap between the impeller and the distribution board (Usually 0.15-0.20mm); replace the mechanical seal; replace the impeller; check the outlet of the pipeline. Third, the vacuum circulation pump motor overheating A. Probable causes: excessive water supply lead to motor overload; motor phase loss; exhaust holes blocked; impeller drag the other components. B. Remedy: Reduce the amount of water supply to the normal range (refer to the instruction manual of the pump); Check the connection is firm; Check the exhaust port; Open the pump cover to adjust the gap between the impeller and other components.

An active ingredient (AI) is the ingredient in a pharmaceutical drug that is biologically active. The similar terms active pharmaceutical ingredient (API) and bulk active are also used in medicine, and the term active substance may be used for natural products. Some medication products may contain more than one active ingredient. The traditional word for the API is pharmacon or pharmakon (from Greek: φάÏμακον, adapted from pharmacos) which originally denoted a magical substance or drug.
