How To Put Cip Reflux Pump Into Normal Operation
CIP Return Pump is different from ordinary centrifugal pumps. Before the centrifugal pump works, the pump body and the water inlet pipe must be filled with water to form a vacuum state. When the impeller rotates quickly, the blades cause the water to rotate quickly. The rotating water flies out of the impeller under the action of centrifugal force. After the water in the pump is thrown out, a vacuum area is formed in the center of the impeller. The water in the water source is pressed into the water inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). In this way, continuous pumping can be achieved. After the first water filling, self-priming does not need to fill water, which is the origin of the CIP return pump.
CIP return pumps all adopt the CIP return pump body structure with axial return liquid. The CIP reflux pump body consists of a suction chamber, a liquid storage chamber, a vortex chamber, a liquid return hole, a gas-liquid separation chamber, etc. After the CIP reflux pump is started normally, the impeller sucks in the liquid stored in the suction chamber and the air in the suction pipe together, and they are completely mixed in the impeller. Under the action of centrifugal force, the liquid carries the gas to the outer edge of the vortex chamber, and a white foam belt with a certain thickness and a high-speed rotating liquid ring are formed on the outer edge of the impeller. The gas-liquid mixture enters the gas-liquid separation chamber through the diffuser. At this time, due to the sudden decrease in flow rate, the lighter gas is separated from the mixed gas and liquid, and the gas continues to rise and discharge through the CIP reflux pump body outlet. The degassed liquid returns to the liquid storage chamber and enters the impeller again through the reflux hole, and mixes again with the gas sucked from the suction pipe inside the impeller, and flows to the outer edge of the impeller under the action of the high-speed rotating impeller. As this process continues over and over again, the air in the suction pipe continues to decrease until the gas is completely sucked out and the self-priming process is completed, and the CIP reflux pump is put into normal operation.
The CIP reflux pump can be used in places where the container for storing liquid is 1-4 meters below the ground level, which is inconvenient for backfilling and adding liquid; the pump can be fixed on the ground level to continuously or intermittently extract and transport various chemical media. When vehicles and ships are loading and unloading chemical media. The self-priming pump can flow in any position to extract and transport to meet your requirements.
The CIP reflux pump is mainly composed of a liquid storage chamber, a vortex chamber, a reflux hole, an impeller, and a pump cover. The pump cavity should be filled with liquid before starting. The gas and liquid in the liquid storage chamber are driven by the high speed of the impeller to suck the gas-liquid mixture into the vortex chamber and pressurize it into the gas-liquid separation chamber. At this time, the specific gravity of air is less than that of liquid, so it naturally enters the pipe network, and the liquid automatically flows back from the reflux hole and mixes with the air in the liquid storage chamber again, and is pressurized by the impeller to enter the gas-liquid separation chamber... This process is repeated until the air in the suction pipeline is exhausted; the medium is transported to any place required by the working conditions. Due to the special design of the pump shell of the CIP reflux pump. Its sealing performance is higher than that of ordinary centrifugal pumps, and the water in the pump casing will not be automatically drained after the motor stops. The motor drives the turbine to rotate at high speed, quickly forming a negative pressure (vacuum) in the pump. Use atmospheric pressure to press water to the pump casing, and then centrifugal lift. The suction range of all CIP reflux pump products will not exceed one atmosphere.
CIP reflux pumps are suitable for clean water, seawater, chemical medium liquids with acidity and alkalinity, and slurries with general paste (medium viscosity <100 centipoise, solid content can reach less than 30%). CIP reflux pumps are equipped with rocker-arm nozzles, and can flush water into the air and disperse it into fine raindrops for spraying. It is a good machine for farms, nurseries, orchards, and vegetable gardens.
