The main characteristics of the tangent pump

the characteristics of the tangent pump, a tangent pump working characteristics, the main characteristics of the tangent pump

tangent pump impeller is open, won't produce axial force in the operation, the impeller does not need to seal, no seal leakage problem. Tangent pump characteristics of this pump features no clearance, because ordinary centrifugal pump adopts open impeller, the clearance between the impeller and casing must be small, such as stainless steel centrifugal pump, and tangent pump this clearance ( 2~3mm) Big, no big influence on the performance of the pump, so the working characteristics of the tangent pump and pumping containing particles can be resistance or viscous liquid. Tangent pump impeller imports generally ranging from pitch idler, in order to suit the requirements of high speed against cavitation performance.

under the same impeller diameter, the main characteristics of the tangent pump is tangent pump lift higher than general centrifugal pump, namely

in low specific speed range, high speed of the pump efficiency is higher than ordinary centrifugal pump, within the scope of high ns is opposite. This is because the high-speed pump liquid and leaves almost no relative velocity, hydraulic loss is small, and no disk friction loss.

because of the increase speed and tangent pump USES a special impeller design, can produce only multistage centrifugal water pump or reciprocating pump in order to obtain the low flow, high lift, low specific speed, without means, have adopted fully open impeller, both from the structure and operating performance has the advantages of multi-stage pump is not tangent pump features as follows:

the characteristics of the tangent water pump 1: the highest Yang can reach 2000 m, operating within the range of low specific speed, because there is little relative flow between liquid and the blade, hydraulic loss is small, therefore, the efficiency is higher than normal centrifugal pump.

the characteristics of the tangent pump 2: in addition to the diffuser nozzle, almost no easy worn parts, and due to the clearance between the pump body and impeller is big, so the appropriate containing solid particles or viscosity greater than zero. 5Pa. S of the liquid.

the tangent pump features 3: belt idler impeller has good resistance to cavitation performance.

the tangent pump 4: the characteristics of being rigid structure, and import and export and symmetrical, so the external pipe load stress is high, good thermal shock, may transport - 130 ~ 260 c of the liquid.

the tangent water pump features five: due to use the structure, such as no seal and between various reason not happen due to erosion caused by the problem of performance degradation.

the tangent pump features 6: the overall structure of the pump closed for the whole, can be installed in the open operation, and compact structure, light weight, small volume, cover an area of an area small, simple foundation engineering.
