In general centrifugal pumps, power always with the increased traffic, that is to say, is a power curve with the rising flow of the curve, which is the use of the pump will bring the question: When the pump Design wow powerlevel operating conditions at run-time, generally speaking, the pump motor power less than rated power, this pump is safe to use; but when the pump head lower, the flow will increase (from the pump performance curves can be seen) , The power has increased. When the traffic conditions over the design flow and arrive at a certain point value, the input pump power may exceed the rated electric power caused by electrical Roll forming machine overload and burned. Motor overload protection or run-time system so that the pump action to stop rotating; or protect the system so that the motor burned out. The pump head design condition at the use of lift, in practice is often encountered a situation in the selection of pump, pump head of the election is too high, but the actual pump is used to reduce lift The use; There was also the case in the use of the pump in working condition is not a good point to determine, in other words the pump flow requirements for regular adjustment yiwu market; there is a need to change the pump locations. These three cases are likely to street overloaded pump affect the reliability of the use of the pump. It can be said that the whole does not lift the pump characteristics (including sewage pump), its use would be to a large extent. The so-called full-lift characteristics (also known as non-overload characteristics) refers to the power curve with the flow increases the speed is very slow, and even better when the flow increased to a certain value, the power will not rise again, it will be Decline in the power curve means that there is WOW Power Leveling a hump of the curve, if so, as long as we choose electric power rating of more than a little hump at the value of power, then in the 0 to the maximum flow of traffic as a whole, in which you Condition-point run, the power of the pump will not pump more than electric power by overload, with regard to the performance of such pumps, or the use of both the selection, will be very convenient and reliable. In addition electrical power distribution and need not be too big, you can save considerable costs of equipment.

Diving skills to buy pumps, sewage pump selection, selection of submersible pumps, sewage pump selection

A building used by a drainage pump sewage submersible pumps, lower liquid pumps, horizontal and vertical sewage pump sewage pump and so on. Due to a building site in general smaller, with a displacement of small forming machine drainage pump may give priority to the use of sewage submersible pump and fluid under the drainage pump, which pumps fluid under Sewerage important place in general use; horizontal and vertical sewage pump sewage pump request traps David basis, since the water-irrigation, and take up some space, so they are less used in construction.
