Abstract
The invention relates to a wallboard for a steam compressor. The wallboard for the steam compressor is composed of a left wallboard and a right wallboard which are firmly connected through reinforcing ribs; two bearing chamber assembly holes are opened in the left wallboard, and the bearing chamber assembly holes are distributed around the center of the left wallboard in a symmetrical mode in the vertical direction and horizontal direction; two mechanical seal assembly holes are opened in the right wallboard, and the mechanical seal assembly holes are coaxial with the bearing chamber assembly holes in the left wallboard. The wallboard for the steam compressor uses the double-wallboard mode composed of the left wallboard and right wallboard, the compressor is well sealed, a fan works without leakage, the total heat insulation efficiency and volume efficiency are improved, and the air volume and pressure characteristic of the steam compressor are improved; the wallboard for the steam compressor is simple in structure, is convenient to dismount, mount and maintain and enables the service life and safety performance of the equipment to be improved.
Description
Technical field
The present invention relates to Compressor Technology field, particularly a kind of vapour compression machine wallboard.
Background technique
Vapour compression machine needs to ensure blower fan No leakage, will have good adiabatic efficiency and volumetric efficiency simultaneously, and traditional wallboard adopts one side mechanical seal, and total adiabatic efficiency and volumetric efficiency can not get good guarantee, and air quantity and Pressure characteristics are also restricted in addition.
Summary of the invention
For overcoming problems of the prior art, the invention provides a kind of overall adiabatic efficiency and the high double mechanical seal wallboard of volumetric efficiency.
The present invention solves the technological scheme that its technical problem takes: this kind of vapour compression machine wallboard, and wallboard is made up of left wallboard and right wallboard, and left wallboard is fixedly connected with by stiffening rib with right wallboard; Described left wallboard has two bearing chamber pilot holes, described bearing chamber pilot hole is symmetrical up and down about left wallboard center; Described right wallboard has two mechanical seal assembly holes, described mechanical seal assembly hole is coaxial with the bearing chamber pilot hole on left wallboard.
Further, described left wallboard and right panel edges are evenly distributed with the identical tapped hole of diameter.
Further, be hollow structure between described left wallboard and right wallboard stiffening rib.
Further, described bearing chamber pilot hole and mechanical seal assembly bore edges are evenly equipped with the identical tapped hole of diameter.
Further, described left wallboard, right wallboard and stiffening rib material are cast iron or cast steel.
To sum up, the beneficial effect of technique scheme of the present invention is as follows: by changing the sealing means of vapour compression machine into 4 shaft extension double mechanical seals, namely two wallboard forms of left wallboard and right wall panel assemblies are adopted, achieve the excellent sealing to compressor, make the work of blower fan No leakage, improve overall adiabatic efficiency and volumetric efficiency, improve air quantity and the Pressure characteristics of vapour compression machine; Left wallboard and the right wallboard hollow structure that adopts stiffening rib to be connected, improves radiating effect in addition, and structure is simple, is convenient to dismounting and maintenance, improves working life and the Safety performance of equipment.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention,
Fig. 2 is right elevation of the present invention.
In figure: 1 left wallboard, 11 bearing chamber pilot holes, 2 right wallboards, 21 mechanical seal assembly holes, 3 stiffening ribs, 4 tapped holes.
Embodiment
Be described in detail to characteristic sum principle of the present invention below in conjunction with accompanying drawing, illustrated embodiment, only for explaining the present invention, not limits protection scope of the present invention with this.
As shown in Figure 1, this kind of vapour compression machine wallboard, wallboard is made up of left wallboard and right wallboard, and left wallboard is fixedly connected with by stiffening rib with right wallboard; Described left wallboard has two bearing chamber pilot holes, described bearing chamber pilot hole is symmetrical up and down about left wallboard center; Described right wallboard has two mechanical seal assembly holes, described mechanical seal assembly hole is coaxial with the bearing chamber pilot hole on left wallboard.
As shown in Figure 2, described left wallboard and right panel edges are evenly distributed with the identical tapped hole of diameter.Further, described bearing chamber pilot hole and mechanical seal assembly bore edges are evenly equipped with the identical tapped hole of diameter, convenient installation, dismounting and maintenance.
Further, be hollow structure between described left wallboard and right wallboard stiffening rib, decrease the gross weight of wallboard and whole compressor, improve radiating effect.
Further, described left wallboard, right wallboard and stiffening rib material are cast iron or cast steel.
It is shaping that this wallboard can complete the main body of wallboard by cast molding technology, then to structure reprocessing such as bearing holes.
This invention is by changing the sealing means of vapour compression machine into shaft extension double mechanical seal, namely two wallboard forms of left wallboard and right wall panel assemblies are adopted, achieve the excellent sealing to compressor, make the work of blower fan No leakage, improve overall adiabatic efficiency and volumetric efficiency, improve air quantity and the Pressure characteristics of vapour compression machine.Left wallboard and the right wallboard hollow structure that adopts stiffening rib to be connected, decreases the gross weight of wallboard and whole compressor in addition, and structure is simple, is convenient to dismounting and maintenance, improves working life and the Safety performance of equipment.
Above-described embodiment is only the description carried out the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; relevant technical staff in the field, to various distortion of the present invention and improvement, all should expand in the determined protection domain of claims of the present invention.
