Description

Stainless steel peripheral pump

Technical field

It the utility model is related to pipeline switching pump configuration, more particularly to a kind of stainless steel peripheral pump.

Background technology

Peripheral pump some is called turbulence pump, regeneration pump etc..Because it is by making liquid produce vorticla motion during impeller rotation Effect and suck and discharge liquid, so referred to as peripheral pump.Peripheral pump is usually used in the supporting of boiler feedwater, in shipbuilding, gently Spinning, chemical industry, metallurgy, machine-building, aquaculture, fixed fire-fighting voltage stabilizing, the thermal effect departments such as the long-range sprinkling irrigation of group, agricultural that change planes have extensively General application.

At present, the notification number of in the market is that CN205207277U Chinese patent discloses a kind of rotation with plane honeycomb screen Whirlpool pump.On principle：With reference to the accompanying drawing disclosed in such scheme, double shrouded wheel rotates at a high speed, the liquid in vane groove by from Mental and physical efforts are got rid of to runner, reach after once supercharging in runner liquid again because in groove liquid be thrown out of to form low pressure, be again introduced into groove, It is pressurized again.The vorticla motion of multiple groove-runner-groove, so as to obtain higher fluid pressure.

When liquid in peripheral pump moves from inlet flow straightener to Exit flow straighteners, in motion around full close to circumference After distance, liquid is thrown away from peripheral pump again, is achieved in repeatedly being pressurized.

Therefore in order to which the path that liquid is walked is grown as far as possible, the actual range of inlet flow straightener and Exit flow straighteners more leans on Closely, and for the ease of installation water inlet pipe and outlet pipe all by opening up setting；Therefore liquid is after inlet flow straightener entrance Always remained in runner, the part residual liquid will influence the use of peripheral pump next time.

Utility model content

The purpose of this utility model is to provide a kind of stainless steel peripheral pump, its advantage be can with it is more convenient must be by peripheral pump The residual liquid discharge of inner flow passage.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of stainless steel vortex Pump, including the pump housing, the linkage that is connected with the pump housing, linkage include linkage motor, the impeller by linkage motor driven；Pump Body, which is provided with, to be used to connect the water-logged base of water inlet pipe, the effluent seat for connecting outlet pipe, and annular channel is provided with the pump housing, described It is provided with communicate with annular channel and section below the pump housing to be stepped the interior groove of structure, the pump housing is provided with and interior groove slides The interior siphunculus of connection, interior siphunculus include hollow slip shaft and end cap, hold the outer peripheral face of cap provided with some empty with slip shaft inside The limbers that chamber communicates, limbers are turned on or separated with annular channel by the slip of slip shaft.

Pass through above-mentioned technical proposal, in use, interior siphunculus is stuck on pump housing inwall, held entirely through Gravitational sliding, end cap Limbers on cap is bonded with pump housing inwall, and now limbers closes, and after water-logged base water inlet, hydraulic pressure will give end cap extra pressure Power so that the cooperation of end cap and pump housing inwall is even closer；After use, pump housing bottom has remained partially liq, passes through slip shaft Above push away end cap and expose limbers, the liquid remained in the limbers guiding pump housing is discharged, and reaches the effect of liquid discharge, without dismounting The whole pump housing, it is simple to operate.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment one：With reference to figure 1 and Fig. 2, a kind of stainless steel peripheral pump, including the pump housing 1 and the linkage that is connected with the pump housing 1 Motor 2, the pump housing 1 are provided with water-logged base 4 and effluent seat 5, water-logged base 4 and effluent seat 5 by flange connect extra water inlet pipe and Outlet pipe.Annular channel 6 is provided with the pump housing 1, the rotating shaft for the motor 2 that links is by key connection impeller 3, and impeller 3 is located at the pump housing 1 It is interior；When impeller 3 rotates clockwise, the liquid in the pump housing 1 flows to effluent seat 5 from water-logged base 4.

Referring to figs. 2 and 3 the bottom side of the pump housing 1 offers the interior groove 7 that section is stepped, and connection is slid on interior groove 7 There is interior siphunculus 8, interior siphunculus 8 includes hollow slip shaft 9 and end cap 10, and the outer peripheral face of end cap 10 is provided with some limbers 11, schemed Showing under state, limbers 11 is bonded with the inwall of the pump housing 1, therefore limbers 11 is in the state of closing, after being slided on slip shaft 9, Fluid communication in limbers 11 and the pump housing 1 on cap 10 is then held, liquid is along the upstream end cap 10 of limbers 11, and to slip shaft 9 Bottom side flowing.The first sealing ring 20 is arranged with the cap 10 of end, the second sealing ring 21 is arranged with slip shaft 9, respectively as one Weight waterproof sealing and double waterproof sealing.

In order to prevent that the liquid in slip shaft 9 because unexpected flow directly out, with reference to figure 3, for closing tie by the bottom wall of slip shaft 9 Structure, and type of tamper evidence 18 is threaded with the bottom wall, type of tamper evidence 18 is realized by turn and dismantled.Remove and slide in type of tamper evidence 18 When sliding on axle 9, the liquid in the pump housing 1 can be flowed out by limbers 11 from the bottom side of slip shaft 9.Such as Fig. 5, the bottom of type of tamper evidence 18 Side is provided with bulge loop 19, and the bulge loop 19 is rigid metal material, is available for users to turn or traction.

With reference to figure 3 and Fig. 4, the bottom side outer peripheral edge of slip shaft 9 is provided with limited ring groove 14, and mother is embedded with the limited ring groove 14 Clasp 12 and sub-buckle ring 13, box ring 12 and sub-buckle ring 13 are rotatablely connected, while box ring 12 and sub-buckle ring 13 pass through fixed spiral shell Bolt 15, fixing nut 16 and pad are realized and are relatively fixed.When slip shaft 9 slides into the pump housing 1, box ring 12 and sub-buckle ring 13 The outer wall of the pump housing 1 will be contradicted, so as to limit the skidding distance of slip shaft 9.In order to increase the ability that slip shaft 9 resets downwards, Spring 22 is arranged with slip shaft 9, one end of spring 22 contradicts the outer wall bottom side of the pump housing 1, and the other end contradicts box ring 12 and son The upper surface of clasp 13.In addition, being also arranged rubber sleeve 17 on slip shaft 9, rubber sleeve 17 wraps up spring 22, realizes insulation blocking Effect.

Discharge the operating procedure of surplus liquid：Type of tamper evidence 18 is unscrewed, type of tamper evidence 18 is removed, overcomes spring 22 from bottom to top Active force promote slip shaft 9, the liquid in the pump housing 1 flows out by limbers 11 from the bottom side of slip shaft 9.

For the normal work of impeller 3 in the pump housing 1 before use, first screwing on type of tamper evidence 18, spring 22 promotes slip shaft 9 to glide, Interior siphunculus 8 realizes waterproof sealing by the first sealing ring 20, the second sealing ring 21 and type of tamper evidence 18.

This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.
