The pure air (66000 NM3/h) that is come by purification system enters supercharger, through three sections seven grades of compressions, it is high that the pressure of air is got, and pressurized air is divided into two strands: one extracts (2 .33 MPa(a) 30300 NM3/h out behind two sections water coolers of supercharger) go to the booster expansion machine system; Another gang (5.8 MPa(a) 35700 NM3/h) draw from the booster compressor final stage, after cooling, enter air separation unit, be provided with two anti-surge valves in the flow process, be respectively FV1020 and FV1025, purpose is to prevent to enter that the tolerance of one section of supercharger and three sections is too small causes surge.
As shown in Figure 1, the former design temperature measuring control point of unit installation site is narrow and small, and circuit can't secure fixation, and is installed in below the bearing shell, easily causes the damage resistive element in maintenance process.
Therefore, provide a kind of and can in long-time running, improve the external anti-interference resistibility of unit, and the measurement and control of temperature mechanism of the normal operation of follow-up job number, be a problem of needing solution badly.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, it is a kind of strong to extraneous interference (wrong report and misoperation occurring as voltage rolling electricity, the frequency interferences of on-the-spot various high frequency devices, instrument itself) resistibility ability that the utility model provides, and can guarantee that unit and follow-up job number normally move, reduce pneumatics unit, the supercharging unit measurement and control of temperature mechanism of potential safety hazard.
The purpose of this utility model is achieved in that
A kind of pneumatics unit, supercharging unit measurement and control of temperature mechanism, comprise supercharging unit 6, the steam turbine 7 that is connected with increase unit 6, the pneumatics unit 8 that is connected with steam turbine 7, be connected with in the outside of supercharging unit 6 and pneumatics unit 8 and support watts 4, be connected with and push away watts 3 supporting watts 4, it is characterized in that: support watts 4 with push away watt both sides, 3 watts of top and be respectively arranged with the first resistance temperature test point 1 and the second resistance temperature test point 2.
Shown pushes away watts 3, supports watts 4 upside and have the fixed orifice that is used for fixing resistance temperature test point and circuit element.
Positive beneficial effect: the utility model has solved pneumatics unit, supercharging unit and has improved in long-time running extraneous interference (wrong report and misoperations occurring as voltage rolling electricity, the frequency interferences of on-the-spot various high frequency devices, instrument itself) resistibility, causes damage to be reduced to zero to resistive element in maintenance process; Guarantee that unit and follow-up job number normally move, and have reduced potential safety hazard.
