What main item should notice when running the system that add medicine?
When running the system that add medicine the key notices the following item:
A. Cast the pressure that add a dot
B. Stroke frequency
C. Suck litre of height
D. Height above sea level
E. Of chemical caustic
When metric pump exit is atmosphere, what what method can raise pump repeat metric precision?
In metric pump discharge valve bedspring of installation a powerful person can be improved repeat metric precision, but the most significant improvement method is the extreme in cop installs a powerful person of a back pressure.
How to adjust back pressure a powerful person?
1.Do not exceed the greatest actuating pressure of metric pump forever.
2.When metric pump is sucking fluid end to have pressure, the pressure that the eduction of pump carries wants taller than the pressure of inspiratory end 1bar at least.
How plan the pulse damper cubage with right choice?
Maneuver measures pump the metric ability of each stroke (Ml) by with 26, can reach the minorrest volume of the pulse damper that reduces 90% pulsatile place need (Ml) .
How the pressure of set relief valve?
The pressure of relief valve can be in limits of metric pump nominal working pressure adjust, do not allow to exceed the greatest actuating pressure of metric pump. Relief valve design is used prevent metric pump to be pressed too move. For example, if the greatest actuating pressure of metric pump is 3bar, the pressure of relief valve should set is 3bar, a few lower perhaps in order to ensure the regular job of metric pump. Exceed pressing the job is one of main reasons that bring about metric pump attaint.
If carry the liquid is not water, how to suck litre of height to calculate?
Of will metric pump rated suck litre of height to divide with metric liquid proportion.
Below what circumstance to use from fill type to suck fluid?
Can apply from fill type to suck fluid below the following circumstance:
1.Metric liquid volatilizes easily;
2.Metric liquid proportion is larger;
3.When needing taller stroke frequency;
4.Metric pump is when job of area of high height above sea level;
5.Bigger storage tank needs when field application, and rely on metric pump suck unworkable circumstance oneself.
Whether give out a few proposals that choose a respect about head of metric pump pump? In involve chemical to be opposite pump head / corrode a respect sealedly, connect regular meeting what to problem appears, how should avoid?
In involve head of metric pump pump, normally the problem is a metric now acid, chloric, fluoride and the circumstance that cross oxidation hydrogen when. Differ with what operate temperature as a result of chroma of medicines and chemical reagents, decide material of specific pump head is qualitative very hard. When metric fluoride, we are recommended choose Viton®Sealed PVC pump head. Add chloric application to great majority, had better choose the NP(organic glass with sealed EPDM) pump head. Oxidize to passing of hydrogenous mixture metric can choose the PTFE pump head with sealed PTFE or head of stainless steel pump only. Of thick hydrochloric acid metric choose the head of organic glass pump with sealed Viton® normally. Thick vitriolic metric and OK the PTFE pump head with choice sealed PTFE. The production chamber of commerce of chemical gives out to suggest relevantly, perhaps consult ProMinent®Chemical and anticorrosive chart will decide chemical and the consistence that contact material to pledge.
