Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The self-supporting machine envelope of a kind of sewage pump as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5 is cooled off the sparge water structure, has the complete sewage pump structure of prior art.Improvements are, lay drum-shaped drainage container 3 on the middle frame 7 of pump, are connected with intake pipe group 1 on drainage container 3 middle parts are tangential, and intake pipe group 1 is communicated with pump discharge pipe 2 and is equipped with into water filter plate 13 in the end; Drainage container 3 tops are communicated with (sealing pair water cavity 8 provides water cooling around mechanical seal 9 for mechanical seal 9) by machine envelope intake pipe group 6 with sealing pair water cavity 8, make cooling water enter mechanical seal 9, and are equipped with machine envelope water inlet pressure regulator valve 5 on machine envelope intake pipe group 6; In the drainage container 3 above the entrance of intake pipe group 1 and the lower position of the outlet of machine envelope intake pipe group 6 be provided with filter plate 4; Drainage container 3 bottoms are communicated with pump inlet pipe 14 by slag liquid leak-off pipe group 11, and are provided with earial drainage modulating valve 12.And machine envelope outlet pipe group 10 two ends are connected with the outlet edge of sealing pair water cavity 8 and the end of slag liquid leak-off pipe group 11 respectively, the end portion 100 of machine envelope outlet pipe group 10 mode that is tilted down.
In the utility model, after the press water at pump discharge pipe 2 places effectively filters large suspended matter by water inlet filter plate 13, import drainage container 3 by intake pipe group 1 is tangential, and in the 3 interior formation of drum-shaped drainage container such as Fig. 4 C to swirling flow liquid.Swirling flow liquid makes clear water up, and again is filtered through filter plate 4, provides the cooling sparge water by machine envelope intake pipe group 6 and through water inlet pressure regulator valve 5 for mechanical seal; Swirling flow liquid sinks slag and suspended matter and sends pump inlet pipe 14 back to by slag liquid leak-off pipe group 11 and earial drainage modulating valve 12, and the cooling water of discharging from mechanical seal 9 places is sent pump inlet pipe 14 back in the lump by machine envelope outlet pipe group 10, slag liquid leak-off pipe group 11, and the design of downward-sloping machine envelope outlet pipe group end 100 can prevent that backflow slag thing in the slag liquid leak-off pipe group 11 is to himself obstruction.Thereby the self-supporting and circulation of mechanical seal cooling sparge water forms a water supply, draining closed system in the realization sewage pump, effectively reduces special-purpose water supply and sewage facility, need not industrial Natural Water.
In sum, intake in the utility model filter plate, intake pipe group, drainage container, filter plate, machine envelope intake pipe group, slag liquid leak-off pipe group, machine envelope outlet pipe group etc. have formed a self-water-supply, draining closed cycle structure with pump.Thereby the self-supporting and circulation of mechanical seal cooling sparge water forms a water supply, draining closed system in the realization sewage pump, effectively reduces special-purpose water supply and sewage facility, need not industrial Natural Water.Save greatly natural water resource, strengthened the protection to environmental protection.
