Abstract
The utility model relates to an improvement of a water sealing pipe structure of a double entry pump, which comprises a water pump pumping chamber cavity, a water sealing pipe part, a sealing cavity or a mechanical seal press cover. One end of the water sealing pipe part is connected with the sealing cavity or the mechanical seal press cover. The improvement of the water sealing pipe structure of the double entry pump is characterized in that the other end of the water sealing pipe part is connected with the lateral wall of the water pump pumping chamber cavity in communicating mode, and the top of the pumping chamber cavity is provided with an exhaust port. The improvement of the water sealing pipe structure of the double entry pump has the advantages of being simple in structure, convenient to mount and maintain, strong in reliability and faster in exhausting and saving cost.
Description
Technical field
The utility model relates to the double suction pump structure, the improvement of particularly a kind of double suction pump water sealing (sealing water) pipe and water pump delivery chamber linkage structure.
Background technique
At present; Conventional double suction pump water sealing (sealing water) pipe mounting type is as shown in Figure 1, extrudes chamber 4 tops at water pump earlier and adorns a four-way 2, is connected water sealing (sealing water) pipe 1 one ends on Seal cage or the machine sealed cover 5 then; The other end connects the four-way side of water pump delivery chamber top of chamber, at last at four-way upper end installing outlet valve 3.Such structural design has the part air unavoidably and gets in the Seal cage when exhaust, do not reach good using effect.In view of the foregoing, in order to guarantee quality of product, must improve existing structure.
Summary of the invention
The utility model purpose is to overcome the deficiency of existing technology, and a kind of improvement of novel double suction pump water sealing (sealing water) pipe structure is provided.
The utility model is achieved in that the improvement of double suction pump water sealing (sealing water) pipe structure; Comprise: water pump extrudes chamber, water sealing (sealing water) pipe parts, Seal cage or machine sealed cover; Wherein, One end of these water sealing (sealing water) pipe parts is connected with Seal cage or machine sealed cover, it is characterized in that: the other end of said water sealing (sealing water) pipe parts is connected with the sidewall perforation that water pump extrudes chamber, offers relief opening at the top that extrudes chamber.
The advantage of the utility model: simple in structure, practice thrift cost, installation and maintenance are convenient, and good reliability, and exhaust is faster.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the structural representation of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Embodiment
A kind of novel water pump seal tubular construction shown in Fig. 2; Comprise: water pump extrudes chamber 1, water sealing (sealing water) pipe parts, Seal cage or machine sealed cover 5, and wherein, an end of these water sealing (sealing water) pipe parts 1 is connected with Seal cage or machine sealed cover 5; Save the four-way on the original structure; Change into water pump and extrude the punching of chamber both sides, let the other end of water sealing (sealing water) pipe parts directly be connected, install simple and convenient with the sidewall perforation of water pump extrusion chamber 4.Simultaneously, offer relief opening 3 at the top that extrudes chamber.
After the improvement, extrude the chamber both sides because of water sealing (sealing water) pipe parts one end is connected in water pump, more near Seal cage, water intake velocity is also just faster in the Seal cage, and hydraulic pressure is also more stable in the chamber.And save four-way, outlet valve is directly installed on the top that extrudes chamber, has avoided middle overcurrent, and water pump extrudes the chamber both sides and outlet valve exists certain height poor because of water sealing (sealing water) pipe parts one end is connected in again, like this with regard to can not be the time because of exhaust air inlet in Seal cage.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
The advantage of the utility model: simple in structure, practice thrift cost, installation and maintenance are convenient, and good reliability, and exhaust is faster.
