Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model and its body embodiment are described in further detail.
As shown in Figure 1, the utility model relate to water hammer abatement function without negative pressure pumping plant, comprise coming grid 1, water regulates bladder tank 2, variable frequency pump 3 and user's pipe network 4, also comprise pumping plant bidirectional compensator 5 and supply water and regulate harmonic wave tank 6, described water regulates the water inlet end of bladder tank 2 and carrys out the water inlet end of grid 1 with variable frequency pump 3 and be connected, described water supply regulates the compensation end of harmonic wave tank 6 to be connected with the compensation end of pumping plant bidirectional compensator 5 with the water inlet end of variable frequency pump 3 respectively, the working end of described pumping plant bidirectional compensator 5 is connected with the water side of variable frequency pump 3, described user's pipe network 4 is connected with the water side of variable frequency pump 3.
The compensation end of described pumping plant bidirectional compensator 3 is connected with the working end of flap valve 15 with pumping plant bidirectional compensator 3 by connecting line, and described flap valve 15 holds the working end of pumping plant bidirectional compensator 5 to be conducting shape by the compensation of pumping plant bidirectional compensator 3.
On the connecting line that the described adjustment harmonic wave tank 6 compensation end that supplies water is connected with the water inlet end of variable frequency pump 3, the water inlet end side of variable frequency pump 3 is provided with electromagnetic relief pressure valve 7.
Described water regulates bladder tank 1 and supplies water to regulate on harmonic wave tank 6 and is respectively arranged with safety relief mouth 8, and safety relief mouth 8 is respectively arranged with superpressure pressure relief device 9.
Described water supply regulates on harmonic wave tank 6 and is provided with gas pressurize automatically supplying apparatus 10 and energy storage device 11.
Described water supply regulates in harmonic wave tank 6 and is provided with liquid level detector 12.
Described come grid 1 and variable frequency pump 3 water side on be respectively arranged with input pressure sensor 13 and pressure sensor output 14.
The utility model cuts down the non-negative pressure method of water supply pumping plant of function in actual applications with water hammer, carry out grid 1, when pressure is normal, variable frequency pump 3 work is supplied to the water supply of user's pipe network 4, now pumping plant bidirectional compensator 5 works, after making pump, press water enters from the working end of pumping plant bidirectional compensator 5, and the compensation end through pumping plant bidirectional compensator 5 enters into supply water and regulates harmonic wave tank 8.
When carrying out grid 1 pressure and being low, the input pressure sensor 13 come on grid 1 sends signal to control circuit, pumping plant bidirectional compensator 5 works, water is made to regulate harmonic wave tank 6 to compensate through the water inlet end of electromagnetic relief pressure valve 7 pairs of variable frequency pumps 3 by supplying water, to make up the deficiency of water, avoid grid 1 produce negative pressure or water hammer occurs.
When there is unexpected power failure or fault of water pump, pressure sensor output 14 sensed pressure of pumping plant declines, in order to alleviate, change in flow that the user's pipe network 4 after pump causes because of unexpected termination of pumping is too fast to have a negative impact to pipeline, being stored in supplies water regulates the band setting-out in harmonic wave tank 6 can be charged in the middle of variable frequency pump water pump water outlet end through flap valve 15, fast repairing according to pressure natural equilibrium principle, makes up because variable frequency pump 3 termination of pumping suddenly causes exit velocity to change the excessive phenomenon of the excessive water hammer caused.
Water hammer stage of development is entered when water soot blower returns; Now the high pressure water that causes of water soot blower is by pumping plant bidirectional compensator 5, working end via pumping plant bidirectional compensator 5 enters into pumping plant bidirectional compensator 5, entering to supply water from the compensation end of pumping plant bidirectional compensator 5 regulates in harmonic wave tank 6, regulate the mixing wastewater with air district in harmonic wave tank 6 that most of water outlet water soot blower that pumping plant occurs is carried out harmonic wave by supplying water, buffering is eliminated.
During unexpected termination of pumping generation water hammer, the air bag in the middle of water adjustment bladder tank 2, by the contraction of self, alleviates the fluctuation carrying out water pressure, also the rate of rise can be reduced simultaneously, for the time is got in the work of superpressure pressure relief device 9, wherein superpressure pressure relief device 9 takes pilot valve to control, its good reliability.
User's pipe network 43 described in the utility model can be the tap water grid of next stage too, also can be other transfer water supply pool.
The above, be only better possible embodiments of the present utility model, and be not used to limit scope of the present utility model.
