How chemical mixed-flow pump operation in order to prolong life

useful extension chemical mixed-flow pump using the method of taking

chemical mixed-flow pump has been more and more attention by people, the use of planning is becoming more and more widely, from simply used to transport water to the present day can transport all kinds of sewage and industrial waste water, construction drainage, liquid feed and so on. About chemical mixed-flow pump is the most crucial problem is reliability problems, due to the use of chemical mixed-flow pump occasions is under liquid. The point should be from the roots, in complete treatment pump in a sealed, overload and other problems, it is a more automatic methods, improve the pump seal reliability and load-bearing ability, extend the use of the pump life.

the use of overloading programming technology of pump:

in general chemical mixed flow water pump, power always follow to increase with the increase of the flow, that is, the power curve is a rising curve with the increase of traffic, the use of the pump will lead to a problem: when the pump working condition of the planning operation, in general, the power is less than the motor rated power of the pump, the flow rate increases, power also will increase. When flow exceeds planning point flow and reached must value, the input power of the pump may be beyond the motor rated power of motor overload and burned down.

when the motor overload operation or maintenance system, continuous rolling pump action or maintenance system failure make motor burned down. lift point of head below planning, is often encountered in practice, a situation is when the pump selection, pump lift selected too high, another case is that there is a situation is to pump requirements often change address. This three of the following message may make the pump overload and affect the use of water pump reliability. , so to speak about not pump total head features, the use of program could have been largely limited.

the use of the hydrodynamic sealing technology vice impeller:

deputy hydrodynamic impeller seal refers to the coaxial reverse direction near the pump impeller HouGaiBan opposite equipment open impeller. When the pump work, vice impeller with pump spindle rotation, the deputy impeller together with the liquid will also rotate, the solid particles into the mechanical seal on the other hand to thwart the medium resistance vice, direction of these two forces are the same, can completely loss dropped to the lowest limit, this part we deputy hydrodynamic impeller sealing technology and overloading programming technology of pump used in chemical industry of mixed flow pump, improve the chemical mixed-flow pump seal reliability and load-bearing ability, extend the use of the pump life.
