Abstract
The invention discloses a kind of hyper-dense phase conveying system material flow adjusting methods, including feed blower and control unit, wherein control unit is used to control the frequency of feed blower, after hyper-dense phase conveying system all conditions are normal and ready, open the outlet valve of feed blower, starting feed blower, the setup pressure value of feed fan outlet is inputted from control unit, control unit is promoted the frequency values of feed blower in the ratio in setting simultaneously, when the actual pressure value for being fed fan outlet is greater than or equal to setup pressure value, control unit stops promoting the frequency values of feed blower and tend towards stability, it is long that the present invention efficiently solves the time existing for tradition adjusting feed blower pressure value method, it is inconvenient, the problem of the practicability is poor.
Description
Technical field
The present invention relates to a kind of hyper-dense phase conveying system material flow adjusting methods, belong to hyper-dense phase conveying system regions.
Background technique
The material flow of hyper-dense phase conveying system is adjusted, i.e. the pressure of feed fan outlet valve is adjusted, tradition side
Then formula needs artificial or automation the variable-frequency motor that allows further according to technique production mainly by directly initiating variable-frequency motor
It is operated by a fixed revolving speed, what these methods greatly increased reaches the time of process requirements material flow, and not
It can determine well and need parameter required for meeting production requirement specific how many suitable, therefore in terms of time and ease for operation
There are significant limitations.
Summary of the invention
The technical problem to be solved by the present invention is a kind of hyper-dense phase conveying system material flow adjusting method is provided, with solution
The problem of certainly time existing for tradition adjusting feed blower pressure value method is long, inconvenient, and the practicability is poor.
The technical scheme is that a kind of hyper-dense phase conveying system material flow adjusting method, including feed blower and
Control unit, wherein control unit is used to control the frequency of feed blower, when hyper-dense phase conveying system all conditions are normal and quasi-
After ready, the outlet valve of feed blower, starting feed blower, from the setting of control unit input feed fan outlet are opened
Pressure value, while control unit is promoted the frequency values of feed blower in the ratio in setting, when the practical pressure of feed fan outlet
When force value is greater than or equal to setup pressure value, control unit stops promoting the frequency values of feed blower and tend towards stability.
When the actual pressure value for being fed fan outlet is greater than setup pressure value, control unit reversely adjusts feed blower
Frequency values, until equal and tend towards stability with setup pressure value.
The beneficial effects of the present invention are: adjusting method of the present invention and traditional comparing up to a fixed frequency starting device
It with apparent advantage, has saved need the time required for reaching material flow first, besides more convenient feed that allows
The frequency values of blower reach most suitable production value, while also having the advantages that easy to operate.
Specific embodiment
Invention is described further below with reference to specific embodiment:
Embodiment 1:
For hyper-dense phase conveying system, the current practical outlet valve pressure of blower that is fed is 0KPa, and feed blower frequency is 0Hz,
Setup pressure value is 3KPa.When system all conditions are normal and ready, opening feed fan outlet valve, starting is fed wind
Machine, from control unit input setup pressure value 3KPa, due to setup pressure value be greater than feed the practical outlet pressure of blower (3 >
0KPa), it is fed the frequency values of blower according to production requirement (such as 1.1 times, 1.2 times) promotion by a certain percentage, is then fed wind
The practical outlet pressure of machine is slowly promoted, until no longer promoting feed when practical outlet pressure is greater than or equal to setup pressure value
The frequency values of blower simultaneously gradually tend towards stability, and the practical outlet pressure of feed blower at this time is 3.06KPa, and frequency values are
29.8Hz.Reach the same feed practical outlet pressure of blower by fixed frequency with traditional operation and compare saving 10 minutes,
And reduces the production requirement for needing to modify fixed frequency repeatedly to reach needs, saved the time and simplify the complexity of operation
Property.
Embodiment 2:
For hyper-dense phase conveying system, the current practical outlet valve pressure of blower that is fed is 0KPa, and feed blower frequency is 0Hz,
Set point pressure is 4KPa.When system all conditions are normal and ready, opening feed fan outlet valve, starting is fed wind
Machine, from control unit input setup pressure value 4KPa, due to setup pressure value be greater than feed the practical outlet pressure of blower (4 >
0KPa), the frequency values of feed blower are promoted by a certain percentage according to production requirement, it is slow to be then fed the practical outlet pressure of blower
It is promoted, until no longer promoting the frequency values and gradually for being fed blower when practical outlet pressure is greater than or equal to setup pressure value
It tends towards stability, the practical outlet pressure of feed blower at this time is 4.02KPa, frequency values 33.5Hz.With traditional operation by solid
Determine frequency and reach the same feed practical outlet pressure of blower to compare saving 15 minutes, and reduces and need to modify fixation repeatedly
Frequency reaches the production requirements of needs, equally saved the time and simplifies the complexity of operation.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
Claims (2)
