Blade type vavuum pump is vavuum pump of machinery of type of a kind of oil seal, it is the basiccest vacuum in vacuum technique acquires one of facility. Blade type vavuum pump can pump the dry gas in removing sealed recipient, if press down device with gas, still can smoke those who divide certain amount to be able to coagulate sexual gas. But it is unwell divide at smoking contain oxygen exorbitant, mordant to the metal, chemical reaction and the contain grain dust gas since oily to pump meeting. Vavuum pump of blade of class having sheet and dual class vavuum pump two kinds. Below, appearance accuses gentleman to introduce the relevant knowledge of blade type vavuum pump for old furniture body!
The structure explains
Blade type vavuum pump is pump of a kind of cubage, its have the aid of runs continuously in pump antrum at blade gas inspiratory compress, finally by vent eduction. Pump is main wait for composition by stator, rotor, blade, rotor is loaded by prejudicial ground inside stator antrum. There are two blades in rotor chamfer, blade bedspring park between two blade. On stator into, vent is departed to be two parts by rotor and blade.
Rotate inside stator antrum when rotor when, its end ministry is clingy below the joint action that blade leaves mental efforts in bedspring tension and itself slide at pump antrum wall, the cubage inside the pitch that will take gas mouth side periodicly expands and inspiratory gas, narrow gradually at the same time the cubage of vent, will inspiratory already gas is compressed, achieve the goal of bleed thereby from vent eduction next.
The characteristic reachs suitable scope
Characteristic:
Inspiratory mouth installation has vavuum pump the thick filter of wire network. The ab extra grit that can prevent solid is inspiratory pump antrum. The exhaust that the installation inside oily segregator has effect of depart of efficient oil gas transfers implement. When stopping pump, inside park is inspiratory buccal inlet valve makes pump is kept apart with the system that be smoked, prevent oil returns the system that be smoked. Pump is cooled by air. XD blade vavuum pump all pump all adopt drive of stretch shaft coupling by the electromotor of straight couplet.
Suitable scope:
1. vavuum pump applies to the vacuumize of airtight system to use. If figuration of vacuum-packed, vacuum, vacuum is attracted.
Limits of 2. entrance pressure: 100Pa, 100000 Pa, exceed vent of vavuum pump of this limits job to will have oily mist generation. Temperature of environment of work of vavuum pump of XD blade type and inspiratory gas temperature should be between ℃ of 5 ℃ ~40.
3. vavuum pump cannot be smoked except water or other liquid. Cannot smoke except explode easily, the combustible, quantity that contain oxygen is exorbitant, caustic gas.
The motor that 4. supplies commonly not explosion proof, if ask explosion proof or other are special,the electromotor when the requirement must accord with relevant standard.
Working principle
Blade type vavuum pump is more medium or small vavuum pump. Blade type vavuum pump has vavuum pump of only course blade and dual class vavuum pump two kinds. Alleged vavuum pump of type of dual class blade, it is in structural admiral series connection of pump of two only course rises. Make geminate form more commonly, spend in order to obtain taller vacuum.
Of blade type vavuum pump smoke fast set as follows with the relation of entrance intensity of pressure: Mix for 1333Pa, 1.33Pa in entrance intensity of pressure 10-1(Pa) issues 1.33 × , its must not smoke fast value respectively under the name of pump fast 95% , 50% with 20% .
Graph 2 it is graph of principle of job of dual class pump, it is comprised by series connection of pump of two only course. When the job, the gas that be smoked enters high vacuum stage via inspiratory canister above all. When inspiratory gas when intensity of pressure is higher, one part gas by exhaust valve 2 eduction, another part enrages class of body classics low vacuum, by exhaust valve 1 eduction. When inspiratory gas intensity of pressure is inferior, although be compressed via high vacuum class, but exhaust valve 2 still cannot open exhaust, can classics is low vacuum pole continues to compress, by exhaust valve 1 eduction, the ultimate vacuum because of dual class pump is taller than only course pump.
