Abstract

The utility model discloses a water-service installation which can pressurize, comprising a rotation shaft with a central through-hole, a casing, and an input port of cooling water, and is characterized in that an impeller is arranged at the outside diameter of an inlet port of the rotation shaft with the central through-hole, a sealing ring is arranged between the rotation shaft with the central through-hole and the casing, and a compression spring is arranged on the sealing ring through a pressing plate. The water-service installation which can pressurize has the advantages of simple structure, convenient processing, and good sealing performance, and constant pressure can be exerted on the sealing ring by the arranged spring, the constant sealing force is always kept, which solves the problem of leakage and plays a role in pressurization on water. The expensive booster pump equipment is omitted.

Description

The waterworks of energy supercharging

The utility model relates to the waterworks in a kind of rig, the waterworks of particularly a kind of energy supercharging.

At stone material, in the construction of glass or curtain wall material, often need process through hole in the above, be used for the bolting connection or decorate other decorations, the instrument of processing normally contains the hollow emery wheel joint of diamond abrasive with the surface of rotation at a high speed, in the process of high speed rotary grinding, temperature between the grinding face tends to up to thousands of degree, like this, the very fast meeting of diamond scaling loss, lose grinding function, therefore, the cooling water that in grinding process, should constantly have certain pressure continuously by input in the grinding tool, when guaranteeing normal grinding, the life-span that can also improve grinding tool, but in the axle centre bore in will rotating external water input at a high speed certain difficulty is arranged.Chinese patent CN-2405682Y discloses a kind of watertight seal that is used for rotary sleeve, it be by pottery go up ring and the ring annular face of being sealed and matched that joins down, last ring and the faying face that encircles down all can be sphere, two sphere inscribes.But this waterworks, its process of manufacture complexity, particularly will grind two absolute ceramic seal masks that coincide has very high technical difficulty, and general workman is difficult to accomplish; In addition,, produce through regular meeting and leak, influence the operate as normal of equipment because the height of process technology level differs; Moreover, when external water source insufficient pressure, can not play pressurization, equipment just can't operate as normal, and for this reason, device fabrication producer all is equipped with expensive booster pump again, has both increased user's burden, uses also inconvenient.

The purpose of this utility model be a kind of simple in structure, good seal performance is provided for the deficiency that solves above-mentioned technology and can improve hydraulic pressure can supercharging waterworks.

In order to achieve the above object, it comprises rotating shaft, overcoat, the cooling water input port of being with central through hole the waterworks of the energy supercharging that the utility model is designed, entry port outer radius in the rotating shaft of being with central through hole is provided with impeller, helicla flute is set, so that carry in water and the rotating shaft when the impeller with water supercharging input tape central through hole by rotating shaft on impeller; Between rotating shaft of being with central through hole and overcoat, be provided with sealing ring, with the gap location leakage of the water that stops the input of cooling water input port from rotating shaft and overcoat, in order to guarantee the service life of sealing property, prolongation sealing ring, on sealing ring, be provided with holddown spring by pressing plate.

The waterworks of the resulting energy of the utility model supercharging, simple in structure, easy to process, the good seal performance of device particularly when ring wear, can apply a constant compression force to sealing ring by the spring that is provided with, remain constant sealing force, to solve seepy question; Simultaneously, owing to be provided with band spiral fluted impeller, when the high speed rotation of impeller, by the axial thrust load of helicla flute to water, can the water pressure that enter be improved and send in the hollow rotating shaft of rotation, play pressurization, can save expensive booster pump and be equipped with water.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an impeller example structure schematic diagram;

Fig. 3 is the cutaway view of Fig. 2.

The utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1

As shown in Figure 1, the waterworks of the energy supercharging that present embodiment is described, it comprises rotating shaft 1, overcoat 2, the cooling water input port 3 of being with central through hole, entry port outer radius in the rotating shaft 1 of being with central through hole is provided with impeller 4, the structure of impeller 4 can be as Fig. 2, shown in Figure 3, helicla flute 8 is set, so that carry in water and the rotating shaft 1 with water supercharging input tape central through hole on impeller 4; Between rotating shaft 1 of being with central through hole and overcoat 2, be provided with sealing ring 4, leak from the rotating shaft 1 of band central through hole and the gap location of overcoat 2 with the water that stops 3 inputs of cooling water input port, in order to guarantee the service life of sealing property, prolongation sealing ring, on sealing ring 4, be provided with holddown spring 6 by pressing plate 5, between the rotating shaft 1 of overcoat 2 and band central through hole, is connected by bearing 9 routinely, rotates with the normal high speed of the rotating shaft 1 of guarantee being with central through hole.
