Performance characteristics of centrifugal pumps
1. High efficiency and energy saving: Using CFD to calculate fluid dynamics, analyze and calculate the relationship between pressure distribution and speed distribution in the pump, optimize the flow channel design of the pump, ensure that the pump has an efficient hydraulic profile, and improve the efficiency of the pump.
2. Convenient installation and maintenance: vertical pipeline structure, the inlet and outlet of the pump can be installed in any position and direction of the pipeline like a valve, which is extremely convenient for installation and maintenance.
3. Smooth operation, safe and reliable: The motor shaft and the water pump shaft are coaxial and directly connected, with high concentricity, stable operation, safe and reliable.
4. Stainless steel shaft sleeve: The mechanical seal position of the shaft is relatively easy to be corroded. Once the direct-coupled pump shaft is corroded, it is easy to cause mechanical seal failure. The STG pump uses a stainless steel shaft sleeve to avoid corrosion, increase shaft life, and reduce operation and maintenance costs.
5. Bearing: In the motor equipped with the pump, the shaft extension end bearing below Y〔Y2〕280 (including the fan end bearing below Y180) adopts enclosed bearings. During normal use, maintenance of the motor bearing is not required.
6. Mechanical seal: The base part of mechanical seal generally uses a rubber bellows structure. The seal on the shaft of the traditional mechanical seal is changed from the line seal of the O-ring to the two-face seal of the rubber, which improves the sealing effect in the clean water medium.
Detailed explanation of the working principle and structural characteristics of the air pump
The so-called air pump is an air pump, and its application is also very wide. It is often seen in industry and daily life. It is a device that removes air from a closed space or adds air from a closed space. So how does it work?
Air pumps can be divided into electric air pumps, manual air pumps, and foot pumps
An air pump powered by electricity continuously compresses air through electricity to generate air pressure. Application of electric air pump: tunnel ventilation, biogas tank aeration, sewage treatment and oxygen blasting, etc.
An air pump powered by hand force continuously compresses air through hand force to generate air pressure. Application of manual air pump: filled balloons or refillable pneumatic toys.
An air pump powered by foot force continuously compresses air through foot force to generate air pressure to work. Application of foot air pump: inflating bicycles, filling balloons or small pneumatic toys.
