Type, basic parameters and main dimensions
Type, basic parameters and main dimensions are shown in Figure 1 and Table 1.3.2 The shaft head of the stirring machine is divided into type I, type II and type III There are three types (Appendix A). Type I shaft head matches HG/T2052 Tang glass equipment transmission device type 1. Type II shaft head matches HG/T2052. Tang glass equipment transmission device type ⅡI machine matches Type III shaft head matches HG/T2052
(Appendix A) Tang glass equipment transmission device type Ⅲ. 3.3 Agitator shaft head connection type and size, Type I shaft head see Figure 2, Table 2, Type II shaft head see Figure 3, Table 3. Ear shaft head see Figure A1, Table A1. Type I shaft head is used for 50L to 5000L glass open stirring container and 2500L to 20000L Tang glass closed stirring container, Type II shaft head and Type III shaft head are used for 50L to 4000L sugar glass open stirring container and 2500L to 4000 sugar glass closed stirring container

Technical requirements for agitator JⅡ40-1030HG/T2051.4-914
4.1 The pipe used for the glass agitator is made of No. 10 or No. 15 steel and is inspected and accepted according to GB8163. 4.2 The manufacture, inspection and acceptance of the glass agitator shall be carried out in accordance with the requirements of ZBG94004. 4.3 The shaft head of the glass agitator must be finely processed after the glass is cut. The agitator used for packing seal must be straightened after the glass is cut, and the shaft end sealing section must be ground. The radial total runout of the agitator shaft sealing section must be calibrated. Less than or equal to 0.2mm, the radial runout of the lower end is less than 0.3%H (H is the distance from the measuring point to the straight rod at the upper end of the shaft) 4.4 The quality classification of sugar glass stirrers shall be in accordance with ZBG94007. 5 Packaging, transportation and storage
5.1 The sugar glass stirrer must be wrapped with soft materials and securely fixed in a wooden box. 5.2 Collisions must be avoided during moving and transportation, and the packaging box must not be inverted. 5.3 The product should be accompanied by a packing list, product certificate and product instruction manual. 5.4
The product should be stored indoors and is not allowed to be stored or stacked in the open air. HG/T2051.491
Appendix A
Type III shaft head of sugar glass agitator
(supplement)
A1 This standard is applicable to Type III shaft head of sugar glass agitator with nominal pressure less than or equal to 1.0MPa, medium temperature higher than -20℃ and lower than or equal to 200℃, and nominal speed of agitator of 80 and 125r/min. A2 This appendix specifies the types and main dimensions of the shaft head of type III agitator for 50L to 4000L glass open mixing vessels and 2500L to 4000L glass closed mixing vessels. A3 Type II shaft head type, basic parameters and dimensions are shown in Figure A1 and Table A1. A4 The relevant dimensions of the glass agitator with type II agitator shaft head are the same as those of the glass agitator with type I agitator shaft head, except for Table A1 of this appendix.
