The impeller and pump body of the sanitary grade high-efficiency centrifugal pump have been accurately calculated and optimized, which can reduce energy consumption and improve overall operating efficiency while ensuring flow rate; Adopting a special impeller structure design to reduce the shear effect on the fluid, especially suitable for media containing particles or sensitive components (such as dairy products, pharmaceuticals, etc.), to avoid damaging their physical and chemical properties; By using high standard sealing devices, liquid leakage is effectively prevented, ensuring the cleanliness of the production environment and complying with safety production regulations.

The equipment has a smooth surface, simple structure, and no dead corners. It supports quick disassembly and assembly, making it easy to clean and disinfect, and meets strict hygiene standards in industries such as food; Usually made of stainless steel material, it can resist the erosion of various chemicals, extend its service life, and adapt to different process requirements; Parameters such as speed and power can be adjusted according to specific application scenarios, and are widely applicable in various fields such as alcohol, fruit and vegetable berry processing, beverage blending, and pharmaceuticals.

Measurement steps for sanitary grade high-efficiency centrifugal pumps:

1. Preparation work

-Equipment inspection: Ensure that centrifugal pumps, flow meters, pressure gauges, vacuum gauges, and other instruments and equipment are in normal condition, and that there are no leaks in the connecting pipelines.

-Initial setting: Fully open the inlet valve of the pump, close the outlet valve, start the centrifugal pump, and gradually adjust the outlet valve to control the flow rate.

2. Data collection and recording

-Multi condition testing: Conduct at least 8 measurements between zero flow rate and usage value under stable operating conditions. The following parameters need to be recorded synchronously each time: flow meter reading (flow rate), tachometer value, inlet and outlet pressure values (obtained through pressure gauge and vacuum gauge), motor power, etc.

-Head calculation: Based on the pressure difference between the inlet and outlet and the vertical distance between the two pressure measuring ports, calculate the head according to the formula H=H pressure gauge+H vacuum gauge+H0 [m].

3. Characteristic curve drawing: Organize the head, power, and efficiency data under different flow rates, draw the characteristic curve of the pump, and analyze whether its performance meets the design requirements.
