Description
Technical Field
The utility model relates to a pump field especially relates to a measuring pump with buffering stationary flow function.
Background
The Water hammer effect is also known as Water hammer effect. The term "water hammer" refers to a water hammer which generates a water shock wave like a hammer blow due to the inertia of a pressure water flow in case of sudden power failure, too fast closing of a valve, reciprocating motion inside a pump body, and the like. The force generated by the water flow impact wave back and forth is sometimes very large, so that valves, pipelines and water pumps are damaged; when the electric water pump is started at full voltage, the electric water pump can be accelerated from a static state to a rated rotating speed within less than 1s, the flow rate in the pipeline is increased from zero to the rated flow rate, and because the fluid has momentum and certain compressibility, the rapid change of the flow rate can cause the pressure overpressure or over-low impact in the pipeline and the phenomenon of 'cavitation', and the impact of the pressure can stress the pipeline wall to generate noise just like a hammer strikes the pipeline, so the effect is called as 'water hammer effect'.
The water hammer effect is extremely destructive: when the pressure is too high, the pipeline is broken, otherwise, the pipeline is shriveled due to too low pressure, and the valve and the fixing piece are damaged; when the power supply is cut off and the system is shut down, the potential energy of the pumping system will overcome the inertia of the motor and command the system to stop sharply, which also causes pressure surges and water hammer effects.
At present, most metering pumps are reciprocating displacement pumps, and when the metering pumps reciprocate inside, the output flow and pressure are intermittent, so that the water hammer effect easily occurs in the water outlet pipeline of the metering pumps, the valves are damaged, the service life is shortened, and improvement is needed for the reason.
