Abstract
The utility model relates to a shield pump body with a radial force balancing double-channel plate. The pump body is a casting, an inlet is disposed on an axial side of the pump body, double channels are arranged on a radial side of the pump body, outer ports of the double channels are outlets, three ribbed plates are distributed in both double channels of the pump body, the shield pump body further comprises a channel plate with the shape corresponding to shapes of the double channels, and the channel plate is respectively connected with the three ribbed plates in the double channels in a welded manner so as to form two parallel channels. The shield pump body adopts a welded double-channel structure, after snagging of the pump body, and the channel plate formed by bending is welded on the three ribbed plates in a tightly attached manner tightly are welded with the channel plate which is in bent forming so as to form the double channels, thereby achieving the effect of balancing radial force. The double-channel plate is not required to be cast, so that the spaces of the channels are expanded, core-making is realized easily, cast of the pump body is simplified, the casting of the pump body is cleaned conveniently, and further the surfaces of the welded double channels are high in smoothness, thereby being favorable for increasing the efficiency of the pump.
Description
Technical field
The utility model belongs to the pump technical field, is specifically related to have the canned motorpump pump housing of balanced radial force double fluid guidance tape.
Background technique
For the pump housing of the higher Pump Suction Nozzle of the big lift of flow footpath, because screw type runner ambient pressure skewness can make impeller produce bigger radial force greater than 100mm.Rub with pump housing choma immovable point (radial force direction corresponding points) around making impeller turnover choma, therefore bigger for flow, the canned motorpump that lift is higher, all need design double-current guidance tape in the pump housing, the double flow channel shape need is identical with pump housing flow channel shape, but differ 180 ° the screw type runner is just in time cancelled out each other to the radial force that impeller produces.Existing double-current guidance tape usually and pump housing runner cast out together, see Fig. 3, but the pump chamber inner flow passage is narrow, not only the making of double flow channel interior core is difficult in the pump housing casting process, the fabricating cost height, and after the pump housing casts out, the inner sand removal difficulty of double flow channel, influence the efficient of pump, be difficult to guarantee pump performance.
Summary of the invention
In order to solve the problem that the making of double flow channel interior core is difficult, sand removal is difficult, fabricating cost is high that the casting of the pump housing and double flow channel slab integral exists, the utility model improves pump body structure, and a kind of canned motorpump pump housing with balanced radial force double fluid guidance tape of new structure is provided.
Concrete Technological improvement plan is as follows:
Have the canned motorpump pump housing of balanced radial force double fluid guidance tape, the described pump housing is a foundry goods, and the axial side of the pump housing is provided with import, and radially a side is provided with double flow channel, and the external port of double flow channel is outlet; Be laid with three gussets in the double flow channel of the described pump housing; Also comprise a runner plate corresponding with the double flow channel shape, runner plate respectively with double flow channel in three gussets be welded to connect, form two parallel runners.
Double flow channel inlet, centre and the outlet port of the described pump housing are respectively equipped with gusset.
The width of described runner plate is slightly less than the double flow channel radial width.
The utility model adopts welding double flow channel structure, after the roughing of pump housing foundry goods, is close to the runner plate of three gusset welding bending formings, forms double flow channel, reaches the effect of balance radial force.The double fluid guidance tape is no longer cast out; Flow channel space enlarges like this, is easy to coremaking, and pump housing casting is simplified, and makes things convenient for pump housing cast cleaning; And weld double flow channel surface flatness height, help improving the efficient of pump.

Fig. 2 is the side view of Fig. 1.
Fig. 3 is an existing pump body structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, the canned motorpump pump housing with balanced radial force double fluid guidance tape comprises the pump housing 1, and the pump housing 1 is a foundry goods, and its axial side is provided with import, and radially a side is provided with double flow channel, and the external port of double flow channel is outlet.Inlet, centre and outlet port are respectively equipped with gusset 3 in the double flow channel of the pump housing; Also comprise a runner plate corresponding with the double flow channel shape 2, the width of runner plate 2 is slightly less than the double flow channel radial width, runner plate 2 respectively with double flow channel in three gussets be welded to connect, form two parallel runners.
Claims (3)
