Description
Technical field
The present invention relates to a kind of weaving air compression system and air compression method.
Background technology
There is 5KG, 8KG, 12KG tri- in large-scale spinnery in order to stabilization gas uses centrifugal air compressor, centrifugal air compressor supply
Air pressure type is planted, 5KG air pressure is used for winding head stabilization gas, and 8KG air pressure is network and suction nozzle gas, and 12KG air pressure is served only for car
Between suction gun repiece.Suction gun population size being opened because of workshop and determining gas consumption, when workshop suction gun is opened seldom, 12KG air pressure is progressively gone up
Rise, cause 12KG gas to exceed system control setting pressure.
Surge is the endemism that centrifugal air compressor operates in generation.When the air mass flow for entering air compressor machine can not make sky
Press produces enough pressure, so that the pressure of external system (exterior line) causes inverse more than the pressure inside air compressor machine
Only valve is closed.At this moment, air compressor machine is not exported, and air is continuously increased in air compressor machine inner accumulation, pressure, until the pressure put aside
More than external system pressure when, air compressor machine internal pressure wash open non-return valve discharge.Due to without enough skies after gas discharge
Gas makes air compressor machine maintain continuous output, and air compressor machine internal pressure declines, and non-return valve is closed, and air is again in air compressor machine inner product
It is tired, when the pressure for accumulating is enough, discharge again, so repeatedly, cause the pressure of output and motor load big ups and downs, inverse
Only valve frequent movement, machine sends bang bang sound, and this phenomenon is just named surge.
Compressor machine outlet pressure is raised, and system pressure is more than outlet pressure, gas flow is dropped to Surging flow.Stabilization
System pressure is high, causes compressor outlet to build the pressure, and gas pours into compressor, causes interior gas low discharge, causes surge to occur.One
As for, 32A to 40A is drive motor maximum current, and 8KG is 32A to 25A, and 5KG is 46A to 69A.
In order to prevent surge from occurring, centrifugal air compressor is designed with the automatic air release valve of anti-surge to centrifugal air compressor, once
Outlet pressure is too high, and close to surge area or when there is surge, the valve can automatically open up emptying valve exhaust to compressor, allow centrifugation pneumatics
Machine not surge and shut down.Its shortcoming is as follows：When suction is robbed out when must lack and uses tolerance few, gas production is more than load capacity, down to meeting
Exhaust emptying, waste of resource；When the system pressure after emptying is also greater than setting pressure, compressor outlet is caused to build the pressure, gas
Body pours into compressor, causes interior gas low discharge, and electric current decline causes surge and shuts down.
