Titanium centrifugal pump should be how to choose

titanium centrifugal pump selection according to the method and

many Chinese company produce pump, pump type is also very heavy and complicated, the relevant state departments are now summarizes various pump sample and product specifications, for the planning and use the unit selection. But how to choose appropriate pump according to produce condition, also is not very easy job, needs to consider the influence of various factors.

the various types of pumps are bound to apply planning and applying condition. Should first according to the nature of the transported liquid and produce condition admit the kinds of pump, and then further recognition of pump concrete types. Liquid viscosity is bigger, less flow and higher lift, appropriate chooses rotor pump. Planning is the most widely used titanium centrifugal pump, therefore, produce chemical use is also the most.

titanium centrifugal pump selection methods and processes:

( 1) Admitted by physical and chemical properties of liquid transport

liquid physical and chemical properties including full temperature, viscosity, density, vapor pressure, corrosion resistance and toxicity and so on, whether or not containing solid particles or bubbles, admit water pump parts material, the type of seals, as well as the method to prevent corrosion and pump cavitation.

( 2) Admit that titanium centrifugal pump flow

according to the requirement of the production conditions, calculate the amount of liquid transport unit time demand, increase must be allowance, as titanium centrifugal water pump flow.

( 3) Admit pump standby rate

with a pump can meet the requirement of the produce, should choose as far as possible when the pump operation. Choose two or more pump in parallel operation in general power is low, can choose two or more pumps in parallel, often also chooses two smaller pumps in parallel, one by one starting respectively.

the standby rate of the pump should be induced to consider the effects of various factors, including the nature of the liquid, process requirements, the reliability of the pump itself operation, repair, pump prices, etc. , to the difficulty of the operation at any time, also does not allow to stop the pump, the intermittent operation of the equipment or ready to stop the pump, can need not spare pump, in order to reduce investment.

( 4) For pump operating point

if the chosen titanium centrifugal pump capacity and head is a bit high, can be used as the margin of the pump, use scheduling export valve opening to scheduling flow and head. If we choose the pump capacity and head is too big, if the selected pump operating point is not allowed within the planning of power, will choose other types of titanium centrifugal pump.
