The utility model relates to a compressor shell, in particular to a large barrel-type compressor shell which is formed by welding and coiling plates in an integrating way; grooves are respectively arranged on the inner walls of front and rear ends of the shell, a fixed ring and a clamping ring which are respectively connected with the shell and an end cover are arranged in the grooves, and the fixed ring and the clamping ring are supported in the groove; the radial cross section of the fixed ring is circular, a plurality of first threaded holes are uniformly distributed along the radial direction; the radial cross section of the clamping ring is circular, and the outer edge of one side surface of the clamping ring is extended outwards axially to form an extension part; a plurality of second threaded holes are uniformly distributed on the clamping ring axially, a plurality of sealing ring grooves are arranged on a contact surface of the end cover and the shell, an O-shaped sealing ring and a pressing-resistance gasket are arranged in each sealing ring groove, the pressing-resistance gasket is arranged at one side of the O-shaped sealing ring and is connected on the inner wall of the sealing ring groove in a supporting way. The large barrel-type compressor shell is formed by welding and coiling plates in an integrating way, the thickness of the shell is greatly reduced, and the weight of shell is lightened, so as to provide convenience for assembly and transportation.

Description

A kind of casing of large-scale barrel-type compressor

Technical field

The utility model relates to the casing of compressor, specifically a kind of casing of large-scale barrel-type compressor.

Background technique

Impeller diameter is a large-scale compressor greater than the compressor of 700mm, is large-scale barrel-type compressor as BCL type compressor (vertical subdivision compressor), and pressure etc. are minimum.The casing of existing large-scale barrel-type compressor adopts the forged steel material to forge and is processed into, and casing thickness is big, the Master Cost height, and the forging process-cycle is long, and manufacturing efficiency is low, has also strengthened manufacture cost simultaneously, has increased workload.

The model utility content

In order to solve the problems referred to above that existing casing exists, the purpose of this utility model is to provide a kind of casing of large-scale barrel-type compressor, adopts sheet material to roll and forms.

The purpose of this utility model is achieved through the following technical solutions:

Casing of the present utility model is that sheet material rolls and is welded as a whole.

Wherein: have groove on the inwall of described casing rear and front end, be equipped with the retaining ring and the snap ring that connect casing and end cap respectively in the groove, described retaining ring and snap ring connect in groove; The radial cross section of described retaining ring is an annulus, and it directly upwards is evenly equipped with a plurality of first tapped holes; The radial cross section of described snap ring is an annulus, and one side outer rim stretches out, forms extension part vertically; On snap ring, be evenly equipped with a plurality of second tapped holes vertically; The internal diameter of extension part is greater than the internal diameter of snap ring; Second tapped hole is positioned at the below of extension part; Have a plurality of seal grooves on described end cap and the casing surface of contact, be equipped with O RunddichtringO and press resistant pillar sheet in each seal groove, described press resistant pillar sheet be positioned at the O RunddichtringO a side, be connected to the inwall of seal groove.

Advantage of the present utility model and good effect are:

1. casing of the present utility model adopts sheet material to roll and is welded into integral body, has significantly reduced the thickness of casing, has alleviated the weight of casing, for assembling and transportation provide convenience; Also reduce cost of production simultaneously, reduced workload.

2. casing of the present utility model adopts retaining ring to be connected with end cap with snap ring, and the intensity height of retaining ring and snap ring is connected firmly.

Embodiment

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

As shown in Figure 1, casing 1 of the present utility model is welded as a whole for sheet material rolls.The diameter of end cap 2 is slightly less than the internal diameter of casing 1, can be contained in the inside, rear and front end of casing 1, is inner housing 8 between the lid of rear and front end.Have groove on the inwall of casing 1 rear and front end, be equipped with the retaining ring 3 and the snap ring 5 that connect casing 1 and end cap 2 respectively in the groove, described retaining ring 3 connects in groove with snap ring 5, and retaining ring 3 all equates with the inside and outside footpath of snap ring 5.

As shown in Figures 2 and 3, the radial cross section of retaining ring 3 is an annulus, and it directly upwards is evenly equipped with a plurality of first tapped holes 4, and bolt is by 4 insertions of first tapped hole, tightly on casing 1.

Shown in Fig. 4～6, the radial cross section of snap ring 5 is an annulus, and one side outer rim stretches out, forms extension part 7 vertically, and the internal diameter of this extension part 7 is greater than the internal diameter of snap ring 5, therefore the other parts of this extension part and snap ring 5 form " L " shape, are convenient to be stuck in the outer edge of end cap 2; Be evenly equipped with a plurality of second tapped holes 6 on snap ring 5 vertically, this second tapped hole 6 is positioned at the below of extension part 7; Bolt is by 6 insertions of second tapped hole, tightly on end cap 2.

As shown in Figure 7, have a plurality of seal grooves (present embodiment is two) on end cap 2 and casing 1 surface of contact, be equipped with O RunddichtringO 9 and press resistant pillar sheet 10 in each seal groove, described press resistant pillar sheet 10 be positioned at O RunddichtringO 9 a side, be connected to the inwall of seal groove.As shown in Figure 8, on the surface of contact of inner housing 8 and casing 1 inwall also many places have seal groove (present embodiment is two places), be equipped with O RunddichtringO 9 and press resistant pillar sheet 10 in each seal groove, described press resistant pillar sheet 10 be positioned at O RunddichtringO 9 a side, be connected to the inwall of seal groove.

Reveal outward in order to prevent machine, between two O RunddichtringOs 9 that are provided with on end cap 2 and casing 1 surface of contact, establish the pressure point, perforate on the relevant position of casing 1 connects pressure gauge, if gas leakage is arranged, then pressure gauge can produce reading, represent that promptly casing radial direction amount of deformation is excessive, the O RunddichtringO lost efficacy, and replaceable diameter is the O RunddichtringO of some greatly, avoid machine to reveal outward, guarantee the compressor proper functioning.
