multistage pump technical performance is better than that of the international similar products

multistage pump is my company in recent years, the development of the domestic leading technical level of high-tech environmental protection energy-saving new products. This pump is applied modern magnetics principles, multi-stage pump adopts the push-pull type magnetic circuit structure, realize the torque without contact, to change the seal for static seal, without leakage corrosion resistant pump. The pump according to the domestic and international standard design, simple structure, easy operation, easy installation and maintenance, technical performance is better than the domestic similar products.

a, multistage water pump advantages:

multistage pump maximum advantages of energy-saving, cover an area of an area small, easy installation, stable performance, coat with 1 cr18ni9ti stainless steel with good quality and shaft seal with wear-resistant mechanical seal, no leakage, long service life. Dealing with axial force hydraulic balance, thus water pump smooth running, low noise, the installation condition is better than that of DL type pump, multi-stage pump can be easy to install in any period of horizontal line in the middle. Hydraulic efficiency high, performance is wide and 25 to import and export of diameter 100 mm, flow 2 ~ 72 tons per hour, head of 25 ~ 150 meters, a total of nine series of more than 70 specifications, multistage pump can completely meet the high-rise buildings, deep well mining of water supply and drainage and fire control facilities, such as hot and cold water is the major industry or general medium, the physical and chemical properties similar to the liquid such as water is the best water pump for the transmission.

2, multistage pump characteristic;

1, the multistage pump is multi-stage sectional structure, its inlet is horizontal direction, vomit export for vertical layout, with 50, 75, 100, 125, 150, such as mouth

diameter, users choose different products according to the requirements of capacity and head diameter and series pump to be satisfied;

2, TSWA multistage pump is mainly composed of inlet section, middle, guide vane, impeller, outlet section and bearing body parts, sealing parts, its structural design is reasonable;

3, multistage pump rotor parts, cast iron impeller, balance disc by medium carbon steel shaft and shaft sleeve, etc, on both ends of the rotor bearing on dry lubrication of rolling bearing, because the leaf

round excellent hydraulic balance for static balance and the balance disc, the pump to run very smoothly, and low noise, small vibration.

4, the combination of water period, middle, and the water surface paper pad by tightening bolts tighten seal, multistage pump to prevent liquid leakage from both ends of the main shaft, a soft packing seal, and at the same time on the shaft is equipped with rubber

rubber hydrosphere, O type rubber sealing ring, with waterproof is into the bushing cavity;

5, to prevent the middle and guide blade wear, AD hoc impeller sealing ring and guide vane quick-wear part, such as when the clearance between the impeller and the wearing parts more than a specified value shall be listed in;

6, multi-stage pump and motor in common cast iron base at the same time, the torque transfer through the elastic coupling.
