What are the structural characteristics of acid and alkali resistant vertical pumps?

　　Vertical acid and alkali pumps are mainly used in the chemical industry, electroplating, metallurgy, etc., can greatly improve the efficiency of the chemical industry, vertical acid and alkali pumps use a variety of materials, such as PVDF corrosion-resistant materials and wear-resistant rubber, etc., today, Schwederbauer Pumps and Valves small editor will introduce the characteristics of the vertical acid and alkali pumps.

　　Structural characteristics of acid and alkali resistant vertical pump

　　1. Acid and alkali resistant submerged pump is vertical structure, with the same caliber of inlet and outlet, and located on the same centerline, it can be installed in the pipeline like a valve, with compact and beautiful appearance, small footprint, and low construction investment.

　　2. The impeller is directly mounted on the extended shaft of the motor, with short axial dimension, compact structure, and reasonable configuration of pump and motor bearings, which can effectively stabilize the radial and axial loads generated by the pump operation, thus ensuring the smooth operation of the pump, no vibration and low noise.

　　3. The shaft seal adopts mechanical seal or combination of mechanical seal, adopts imported titanium alloy seal ring, medium-sized high-temperature-resistant mechanical seal and adopts hard alloy material, wear-resistant seal, which can effectively prolong the service life of mechanical seal.

　　4. Easy installation and maintenance, no need to dismantle the piping system, advanced hydraulic model design, high efficiency, high energy saving.

　　5. Pump internal impeller, pump casing and its main accessories using stainless steel stamping and molding, the flow channel is particularly smooth, the shaft tile, bushings with hard alloy, with a super service life, to prevent the occurrence of secondary pollution.

　　6. Generally, it is necessary to use materials with high corrosion resistance, because the pump needs to go through a long time of industrial production operations, acid and alkali resistant vertical pump pump body is made of FRPP, CFRPP, CPVC and PVDF, which have the characteristics of high temperature and corrosion resistance.

　　7. Acid and alkali vertical pump adopts one-piece design, good corrosion and abrasion resistance, high mechanical strength, not easy to aging, can greatly improve the working efficiency. It can satisfy many kinds of working scenarios and can withstand high working pressure.

　　Performance characteristics of acid and alkali resistant vertical pump

　　1, high efficiency and energy saving: CFD calculation of fluid dynamics, analysis and calculation of the pump pressure distribution and velocity distribution relationship, optimization of the pump flow design, to ensure that the pump has a highly efficient hydraulic shape line, improve the efficiency of the pump.

　　2、Convenient installation and maintenance: vertical pipeline structure, the pump can be installed in any position and any direction of the pipeline like a valve, which makes the installation and maintenance extremely convenient.

　　3、Smooth running, safe and reliable: the motor shaft and pump shaft are coaxial direct connection, high concentricity, smooth running, safe and reliable.

　　4、Stainless steel shaft sleeve: the position of the shaft seal is relatively easy to be corroded, once the shaft of the pump is corroded, it is easy to cause mechanical seal failure, so as to avoid the occurrence of corrosion, improve the life of the shaft and reduce the operation and maintenance costs.

　　5, bearing: the pump is equipped with a closed bearing in the motor, after normal use, to carry out maintenance of motor bearings, are viewed.

　　6, machine seal: mechanical sealing base parts can generally choose rubber bellows structure, using the traditional mechanical seal in the shaft seal by the O-ring of the line seal or rubber parts of the two face seals, so that the sealing effect in the clear water medium to improve the sealing effect.
