Recirculating water vacuum pump operation flow
Open the lid of the tank and inject clean cold water. The height of the water level is limited to just below the overflow nozzle.
Turn on the power plug, turn on the start switch, and the pump starts to work.
Blocking the mouthpiece with your finger, the corresponding vacuum gauge can reach -0.1Mpa vacuum indicating that the pump is working properly.
Each nozzle of the machine has a one-way check valve. For the sake of safety, more effective measures should be taken to prevent the pump from stopping. The water in the pump will flow back into the pumped container. The specific methods are: (1) Breaking the tube between the vacuum pump and the pumped container. (2) Stopping the work is about to be pumped out of the container.
The ultimate vacuum of the circulating water vacuum pump is limited by the saturation vapor pressure of the water. For long periods of operation, an increase in water temperature will affect the degree of vacuum. In this case, connect the water outlet (lower mouth) at the back of the device to tap water. Spill outlet (upper mouth) drainage. Appropriate control of flow can keep the water temperature in the tank from rising, and the vacuum level is stable.
2. Maintenance:
Maintaining clean water frequently is the key to long-term stable operation of equipment. Change the water and clean the water tank regularly. Do not smoke dust and solid matter.
Some corrosive gases can lead to deterioration of the water quality in the tank, resulting in bubbles, affect the degree of vacuum, it should pay attention to continuously change the water.
For particularly strong corrosive gases, it should be carefully judged whether there is reaction with the materials used in this equipment, and use with caution.
If the vacuum does not go up, it is firstly judged whether the pumped container is leaking or the pipe is loosened. In the case of a pump problem, check the inlet or air lines for blockage or loosening of the leak.
The circulating water vacuum pump motor does not turn and should check the power supply or fuse.
The ultrasonic level sensor integrates non-contact switch, controller and transmitter into one, suitable for small storage tanks. Ultrasonic liquid level sensor flexible design can be used in the integrated system or a substitute float switch, electrical conductivity and static pressure type sensor, and also suitable for the fluid flow control and chemical feed system of integrated application of ultrasonic liquid level sensor is widely used in all kinds of atmospheric storage tank, tank, small cans and small container, the pump lift stations, waste water storage tank, etc.
