The characteristics of high speed pump and structure

high-speed pump structure, the characteristics of high speed water pump

the structure of high speed pump is mainly composed of and growth of the motor and pump body of three parts, the structure of high speed pump is compact. The growth of high speed pump all adopt closed structure, can be used in installed outdoors. If the motor power exceeds the l60kW, horizontal high-speed pump should be used; At present the most commonly used high speed pump power is 7. 5 ~ 132 kw product, the vertical structure of high speed water pump is one of the largest product usage.

due to the high speed pump in the direction of miniaturization, low cost, high reliability and so on development, make new high-speed pump out of its speed restrictions, innovate and seriation. Traditional high-speed pump gear speeder with complex, not only expensive, maintenance is difficult, and sometimes also subject to the conditions of the installation space, as shown in figure 6 - high-speed pump structure of the system 56 a. Adopts variable-frequency high-speed motor coaxial straight league new frequency straight league pump, pump structure diagram as shown in figure 6 - at a high speed 56 b.

( 1) The characteristics of high speed pump

1) High-speed pump shaft and motor shaft or growth axis straight league, high-speed pump impeller is cantilever.

2) High-speed pump room diffuser as components in a shell, is advantageous for the replacement, repair and change the impeller diameter.

3) High-speed pump suction and discharge arrangement on the same line.

4) High-speed pump cyclone separator is installed inside, the pump pumping liquid purification, will purify liquid to mechanical seal to extend the life of the seal.

5) High speed pump pressure with annular water chamber, pressurized water chamber with 1 - around Two diffusion tube, diffusion tube inlet is equipped with the nozzle, the size of the nozzle has a great influence on the performance of the pump.

6) High-speed pump impeller front loading idler.

( 2) Speeder high-speed pump are implemented through the speeder, so growth is one of the key parts of high speed pump. Speed-up machine vibration should be small, under no circumstances shall not exceed the drive motor noise, no maintenance should be continuous operation for several years, and almost don't have to replacement parts. Speeder primary growth and secondary growth of two types. Use small modulus involute gear speeder. Trapped helical to produce axial force, to withstand the thrust of the thrust bearing is difficult to manufacture, and despite the helical gear meshing efficiency is high, but I can't guarantee machining accuracy, because the tooth profile, the pitch precision is not high, can wear and impact of meshing efficiency. Straight gear machining accuracy easy to guarantee, and does not produce axial force. Gear pitch processing precision is less than 2 ~ 3 um, gear material for special steel, the permeability of ammonia or carburizing treatment HRC hardness of 62 ~ 65. Speed-up machine shell is divided into two and a half, and when combined with each other without seam allowance, and dowel locating. Shell material for aluminum alloy, bearing is a speeder block sliding bearing with two side thrust bearing combination. Speeder lubrication is around the speeder shell and the top of the pack several nozzle, at the end of the motor input shaft lubrication oil pump, oil pump of oil through a filter into the nozzle, the oil spray mist lubrication gear and bearing.

( 3) Inverter because the inverter to small, low cost, high reliability, better make new high-speed pump out of its speed about speed, innovate and seriation. Traditional tangent water pump gear speeder with complex, not only expensive, maintenance is difficult, and sometimes also of limited installation space. Adopts variable-frequency high-speed motor coaxial straight league new high-speed pump light volume, due to the operation condition by using the method of changing speed is consistent with the actual requirements parameters, compared with traditional self-reliance type valve flow adjusting and energy saving effect is significant.
