Within the pump (pump core) is an axially split volute to the split ring section pump with radial compared to the pump, the main advantages are:

1) volute pump flow in a wide range of its high efficiency and smooth performance curve, which often regulate the flow of power and requires relatively small changes in the export of high pressure feed pump is a significant advantage (Figure 1-10).

2) a larger volute pumps to allow watershed corner gap, without affecting the pump's hydraulic performance, mechanical point of view from the water pump can be reduced in the non-design flow instability, which produces a pressure fluctuation level also low.

3) scroll across the tongue and throat can be reduced within the high-speed liquid erosion and reduce abrasion damage after impact.

4) test showed that interior volute pump impeller position on the worm is not particularly sensitive to the axial offset, which is multi-stage guide vane than the spread of multi-stage pump is also an advantage.

5) pump core is on casting the next two identical semi-spiral form, just use the light-load bolts to tighten, so it is easy to disassemble and assemble, with the ring section multistage pump compared to the assembly overhaul asked the shorter.

6) Double volute symmetrical design provides the rotating parts (rotor) of the deflection bias added to the lower part of the scroll on the possibility, because the shaft is flexible land in the state running. This would ensure that all rotating concentric maintain the necessary clearance, and improve the reliability of high-speed pump operation.

7) All high-speed balancing rotating components as a whole after assembly, without dismantling the rotor part, directly into the lower volute, and can be assembled on the scroll, to ensure accuracy, saving time and reliable.

8) In case of emergency, the rotor parts can be quickly from the volute on the back hanging out and install the rotor, and the radial and axial clearance is easy to measure, easy maintenance and time is short.

9) within the pump volute impeller on the rotor is placed relative to the use of back to back, the results of the pump in the operation of the water thrust (ie axial force) to self-balance, while first-stage double suction impeller impeller, and do not need to use a small gap, high pressure drops are prone to accidents balancing device (such as the balance disc or balance drums). Consider the presence of residual axial force and rotor axial position, and set up a relatively low carrying capacity of thrust bearing, so that the feed pump has a higher safety factor

lO) because the relative arrangement of the axial thrust of the impeller through the group to achieve a balance, the maximum pump pressure by turning the rotor clearance concentrated in the center of the wall and spit out, these pressures is about 50% of the total pressure head. And turning to ask gap is uniform, the pressure drop per unit length equal to, so normal wear and tear, the small area will not have a big drop, the gap in the wear and tear that equal opportunity for all, so to ensure the smooth operation of the pump.

11) As the volute of the pump is on, the next two and a half spiral completely symmetrical form, snail-shaped across the tongue into a 180. Precise positioning, pumps in operation can be self-generated radial force balance, and enhance the operational stability of the rotor (Figure 1-12).

12) back to back using the scroll pump impeller speed 6000 ~ l0000r/min can run reliably, and thus meet the supercritical, ultra supercritical thermal power units of the high pressure feed pump (usually outlet pressure at 29 ~ 40MPa) needs.

(1) the overall structure

Because supercritical unit and single large-capacity unit parameters increase, so the demand for high-pressure feed pump to further increase demands for safe and reliable water pumps, high efficiency and good controllability, maintenance, asked short. The world's super-critical units are dual-use high-pressure feed pump housing cylinder-type, multi-stage centrifugal pump, instead of a single shell with little or multi-stage centrifugal pump. Barrel to the pump housing can be permanently welded to the body of water on the road, inside the pump (ie pump core) to be pumping, this type of feed pumps for high pressure and high pressure, applied to thermal shock, for changes in unit load . The level of support for the center of the pump cylinder, with a separate base or rigid common base. To pump high-pressure side seal commonly used spiral wound gasket seal. Generally use a large bolt disassembly required torque wrench or electric heating device, convenient and reliable. Impeller and the shaft too tight fit, to pass key link torque shaft is rigid shaft. Double-shell high-pressure pump to the pump within the (often called the pump cell), the current international structure, there are two forms: one based on the U.S. original ByronJackson (referred to as 8.J company, has been with Flowserve, IDP, Adrich other companies reorganized into FlcwservePumpDivision, referred to as FPD's), represented by an axially split volute pump within the open structure, including the now Japan EBARA (that is, Ebara). MITSVBISHI (ie Mitsubishi pump) are all introduced to the U.S. company's original 8.J pump manufacturing technology.

The other is a German company KSB valve within the pump, represented by radial split multistage segmental structure, including the UK's Weir Pumps, Sulzer Pumps Inc. and the former Soviet Union (now Ukraine) pump company is radially split multistage segmental structure. Manufacturing technology. The other is a German company KSB valve within the pump, represented by radial split multistage segmental structure, including the UK's Weir Pumps, Sulzer Pumps Inc. and the former Soviet Union (now Ukraine) pump company is radially split multistage segmental structure.

United States using high-pressure feed pump are within the axially split volute pumps for the multi-stage centrifugal pump in open structures. Shenyang Pump Co. in cooperation with the U.S. FPD production of HDB-type feed pump for Huaneng Qinbei power plants.

(2) within the pump is an axially split volute-type high-pressure feed pump structure

The United States as the representative of FPD's double-barrel pump to split volute shell structure of high-pressure boiler feed pump, run for many years to prove: that the pump is particularly suitable for high pressure or high pressure boiler feed water, and safety in variable load reliable operation, which allows frequent start and cold start, can withstand thermal shock, wear and asked a small gap. Mainly from the outside cylinder, pump cover, inner spiral, rotor, bearing five components.
