Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.
A kind of vacuum generating equipment of sterilizer as shown in Figure 1, including steam sterilizer, vacuum generator, the steaming
Vapour sterilizer is set as pulsation vacuum sterilizer, and steam sterilizer includes sterilization chamber 10, air filter 1, condenser 3, distilled water
Water tank 4, condensed water collecting box 5, water pump 6, safety valve 2, vacuum pump valve V5, the air filter 1 pass through intake valve V2 points
It is not connected with exhaust valve V1, sterilization chamber 10, safety valve 2, pressure sensor 7, institute is equipped between the safety valve 2 and intake valve V2
It states exhaust valve V1 to be connected with one end of condenser 3, the sterilization chamber 10 passes through between drain valve V4 and condenser 3 and exhaust valve V1
Pipeline be connected, the other end of the condenser 3 is connected with distilled water water tank 4, the condenser 3 and distilled water water tank 4
Between be equipped with vacuum pump valve V5, the distilled water water tank 4 is connected with condensed water collecting box 5, and condensed water collecting box 5 passes through water
Pump 6, water-pump valve V3 are connected with sterilization chamber 10；
Vacuum generating equipment as shown in Figure 2 includes vacuum generator 9, air pump 8, and it is empty that the vacuum generator 9 is equipped with compression
Gas import A1, vacuum port, exhaust outlet A2, the compressed air inlet A1 are connected with air pump 8, and vacuum port and vacuum pump valve V5's goes out
Mouth pipeline is connected, and exhaust outlet A2 is connected with distilled water water tank 4.
Specifically, the vacuum generator 9 is designed to that supersonic nozzle type, working principle are to utilize jet pipe high speed jet pressure
Contracting air forms jet stream in nozzle exit, generates volume and inhale flowing, under Involving velocity, so that the air around nozzle exit is not
It is sucked away disconnectedly, so that the pressure in adsorbent chamber is down to atmospheric pressure hereinafter, formation certain vacuum degree, by hydrodynamics it is found that right
In the continuity equation of incompressible air gas (gas is in low speed into can be approximately considered is incompressible air)
A1v1=A2v2
The area of section of A1 in formula, A2---- pipeline, m2；
V1, v2---- air-flow velocity, m/s；
From the above equation, we can see that section increases, flow velocity reduces；Section reduces, and flow velocity increases
For horizontal pipeline, it is by the Bai Nuli ideal capacity equation of incompressible air
P1+1/2 ρ v12=P2+1/2 ρ v22
P1 in formula, P2---- section A 1, corresponding pressure at A2, Pa；
V1, v2---- section A 1, corresponding flow velocity at A2, m/s；
ρ --- the density of-air, kg/m3；
From the above equation, we can see that flow velocity increases, and pressure reduction, as v2 > v1, P1 > P2.When v2 increases to certain value, P2 will be small
In an atmospheric pressure, i.e. generation negative pressure.Therefore negative pressure can be obtained with increase flow velocity, generate suction.
Classify by nozzle exit Mach number M1 (the ratio between exit velocity and local velocity of sound), vacuum generator can be divided into subsonic speed
Device cast (M1<1), velocity of sound nozzle type (M1=1) and supersonic nozzle type (M1>1).Subsonic speed jet pipe and velocity of sound jet pipe are all
Shrink nozzle, and supersonic nozzle type must first shrink to expand shape jet pipe (i.e. Laval nozzle) afterwards.Maximum sucking in order to obtain
Pressure at flow or highest suction inlet, vacuum generator are generally configured to supersonic nozzle type.
