What are the requirements for the use of sanitary centrifugal pumps?
①The steering of the driver should be the same as that of the pump;
② Identify the control of pipeline pump and coaxial pump;
③ Each fixed connecting part should not be loose, and the specification and quantity of lubricant added to each lubricating part should comply with the provisions of the technical documentation of the equipment;
④ The parts of the sanitary centrifugal pump that require pre-lubrication must be pre-lubricated in accordance with the regulations;
⑤ All display instruments and safety protections should be sensitive, accurate and reliable;
⑥ The crank should be flexible and not exhibit any unusual phenomena;
⑦The pump body should be preheated before the test operation of the sanitary centrifugal pump, the temperature should rise evenly, and the temperature rise per hour should not be greater than 50℃; The temperature difference between the surface of the pump body and the process line with the working medium entry should not be greater than 40℃.
What should we pay attention to when buying a sanitary centrifugal pump?
When choosing the right sanitary centrifugal pump, attention should be paid to the type and performance of the selected pump, in order to meet the requirements of the process parameters such as device flow, delivery height, pressure, temperature, cavitation flow, suction height, etc. to fulfill. to ensure that the mechanical reliability of the sanitary centrifugal pump is high.
Ensure that the power of the sanitary centrifugal pump is greater than 120% of the working power; Consider the economic performance of the pump and the convenience of maintenance. Choose a manufacturer with good reputation, and it is convenient to solve problems in the factory. the specific details should be as detailed as possible to avoid unnecessary pumping problems.
How does the sanitary centrifugal pump work?
The working principle of centrifugation is the performance of the inertia of the object, such as the drops of water on the umbrella. When the umbrella rotates slowly, the water drops rotate with the umbrella. This is because the friction between the umbrella and the water drops gives the water drops a centripetal force. However, if the umbrella rotates faster, the friction is not enough to bring the water drops into a circular movement, then the water drops move away from the umbrella and move towards the outer edge, which is called centrifugal.
The sanitary centrifugal pump is that the impeller rotates when the pump is filled with water to generate centrifugal force, and the water in the impeller channel is hurled to the periphery, and under the action of centrifugal force flows into the pump housing, so the pressure of the measuring wheel decreases to the center.
Xusheng Valves (Compass Valves) was founded in 2011 as a global manufacturer of sanitary valves and has become one of the leading valve manufacturers for high precision stainless steel sanitary valves, pipe fittings, pumps and tanks.
