Abstract

The utility model relates to a pressing pump, consisting of a pump body, a rotor, a rotor cover and a receiving pipe. A water inlet is arranged on one end of the pump body, a rotor shaft is arranged on the end with a water inlet of the pump body through a bearing and the central outflow pipe of the receiving pipe is arranged on the other end of the pump body. The rotor is arranged with a bilayer wall, wherein, the inner wall is fixed and connected with the rotor shaft, the outer wall is sleeved on the rotor shaft and vanes are arranged inside the cavity between the two walls to join up the inner and outer walls. As the pump changes the prior pressing pump with a water inlet and outlet both arranged on one side of the pump body to be the structure that the water inlet and outlet are arranged on both sides of the pump body respectively and the rotor is designed to be a radial water inlet and axial water outlet, thereby achieving the requirements of a high pump lift and a large flow rate; moreover, a high-pressure water outlet needs no sealing and a sealing is only needed for a low-pressure water outlet, as a result, the demand for sealing is relatively lower the integral structure is simplified and the cost is relatively reduced as well.

Description

The punching press pump

Technical field

The utility model relates to a kind of water pump, specifically, relates to a kind of punching press pump.

Background technique

Water pump has multiple, comes comparison with regard to single stage centrifugal pump and single-stage punching press pump, and the advantage of single stage centrifugal pump is that flow is big, but lift is lower.And single-stage punching press pumping head height, simple in structure, high pressure do not have leakage etc.Because at present the entery and delivery port of punching press pump all is arranged on the same side of punching press pump, referring to the CN01270818.6 patent application, has limited the raising of flow, though so the punching press lift of pump is high, flow is less, using scope is subjected to certain restriction.In order to give full play to the advantage of punching press pump, enlarge its utilization scope, just must further improve the flow of punching press pump, this problem is a difficult problem that exists in the industry always.

The model utility content

The purpose of this utility model is to overcome above-mentioned defective, and a kind of lift height, punching press pump that flow is big are provided.

Punching press pump described in the utility model comprises body, rotor, rotor cover and adopter.One end of described body has water intake, and rotor shaft has an end of water intake by Bearing Installation at body, and the center outlet pipe of adopter is arranged on the other end of body.Described rotor has inner and outer wall, and its inwall is fixedlyed connected with rotor shaft, is evenly distributed with blade in the cavity between Liang Bi, and two walls are coupled together.

The inwall of described rotor is a hemisphere, and outer wall is by forming with concentric hemisphere and the cylinder of inwall, is separately installed with rotor cover at the end face of inside and outside wall, forms second closed chamber and first closed chamber, at each indoor adopter that is provided with.

Described blade is 6, and it is shaped as multi-section circular arc, and the laying angle of its water intake is 18 °-25 °, and the laying angle of water outlet is 15 °-40 °.

The laying angle of described water outlet is 20 °-30 °.

Spacing between the outer wall of described rotor and the spacing between the rotor shaft and inwall and the outer wall is determined according to required flow.

Punching press pump described in the utility model becomes radially water inlet with rotor design, axially water outlet, the water-in and water-out that changed existing punching press pump all in the setting of the same side of water pump, are side water inlet, the opposite side water outlet, thereby realized requirement high-lift, big flow, and seal arrangement need be set owing to have the waterexit end of high pressure, only the low voltage terminal in water inlet is provided with seal arrangement, therefore, requirement to sealing reduces relatively, and overall structure is simple, the also corresponding reduction of cost.

Description of drawings

Fig. 2 is the structural drawing of described punching press pump rotor;

Fig. 3 is the D-D sectional drawing of Fig. 2.

Embodiment

Referring to Fig. 1, punching press pump described in the utility model comprises body, rotor, rotor cover and adopter.One end of body 2 has water intake 8, and rotor shaft 9 is installed in the end that body 2 has water intake 8 by bearing 1, and the center outlet pipe of adopter is arranged on the other end of body.

Participate in Fig. 2 and Fig. 3, described rotor 3 has inwall 16 and outer wall 15.Described inwall 16 is a hemisphere, fixedlys connected with rotor shaft 9, and outer wall 15 is by forming with concentric hemisphere and the cylinder of inwall.Be evenly distributed with 6 in the cavity between Liang Bi and (only express two blades among Fig. 3, all the other omit the end and draw) blade 11, two walls are coupled together, blade be shaped as multi-section circular arc, the laying angle of its water intake is 18 °-25 °, the laying angle of water outlet is 15 °-40 °, is preferably 20 °-30 °.Spacing between the outer wall 15 of rotor and the spacing between the rotor shaft and inside and outside two walls is determined according to required flow size, is 100m as flow ³/ h, its spacing are 12mm-15mm.The formation axial water outlet of radially intaking like this, thus can realize respectively both sides water inlet and water outlet from body.

Punching press pump described in the utility model can be a single-stage punching press pump, also can be multistage punching press pump.So-called " single-stage punching press pump " is meant that this pump only has an adopter, and " multistage punching press pump " is to have a plurality of adopters.What Fig. 1 represented is the two stage pump with two adopters.The inwall 16 of the dual-layer wall rotor of this pump is shorter than outer wall 15, and rotor cover 5,7 is installed in the end face of inside and outside wall respectively, makes it to form two closed chambers, promptly second closed chamber 13 and 12, two adopters of first closed chamber 4,6 be installed in respectively these two indoor.The center outlet pipe 14 of adopter stretches out from the other end of body 2.This design of the present utility model is greatly improved the flow of water.

Water is entered by water intake 8 when rotor 3 rotates, because rotor high-speed rotation, water increases through the rotor pressure with blade, enter first closed chamber 12, enter adopter 6 then, behind adopter 6 process rotor cover 5 further raising pressure, enter second Room sealing 13, enter adopter 4 again, have of the center outlet pipe outflow of the water of high pressure by the opposite side that is arranged on body.

If single-stage punching press pump has only an adopter, promptly there is not the adopter 4 among Fig. 1, in other words, water is directly flowed out by center outlet pipe 14 after entering adopter 6.

According to needed lift height a plurality of adopters can be set, only need between each adopter, to set up rotor cover the adopter isolation is got final product.
