Abstract
The utility model discloses one and make stable, the accurate device of Small Flow Control, comprise pump, arrange recirculatory pipe, recirculatory pipe one end is communicated with the output pipe of pump, one end connected system pipeline or pumped (conveying) medium source place.Make pump remain in rational scope at normal use procedure middle pump body rotating speed, stability and the control accuracy of system are improved, and pump is large can Feedback medium by opening recirculatory pipe, need not change pump, save time, cost.
Description
Technical field
The utility model belongs to high-precision flow opertaing device technical field, is applicable to various fluid media (medium), is specifically related to one and makes stable, the accurate device of Small Flow Control.
Background technology
Flow control is widely used in modern enterprise.Flow control stable and be accurately very important in a lot of field, it is not only related to the economy and high efficiency that medium uses, and is also related to the improvement of system performance, even decides the realization of certain function.Under normal circumstances, all can carry out the type selecting of the pump housing according to the scope of system flow demand when designing.But often commercially do not have and the pump needing capacity to match, be difficult to meet technological requirement, just need to be realized by alternate manner.If pump selects little, then technological requirement cannot be met.If pump selects large, just there will be the problem of instability or control accuracy deficiency when flow control.
Utility model content
The one that technical problem to be solved in the utility model is the problems such as the large or control accuracy of pin Small Flow Control fluctuation is not enough and provides makes stable, the accurate device of Small Flow Control.
Following technical scheme is adopted: one makes stable, the accurate device of Small Flow Control, and comprise pump, arrange recirculatory pipe, recirculatory pipe one end is communicated with the output pipe of pump, one end connected system pipeline or pumped (conveying) medium source place for solving technical matters of the present utility model.
The pipeline that the output pipe connectivity part of described recirculatory pipe and pump is put to user is provided with flowmeter.
Described recirculatory pipe arranges manual modulation valve.
Described pump is the volume pump of adjustable speed.
Described recirculatory pipe with realized by threeway being communicated with of output pipe of pump.
Technique effect of the present utility model is: make pump remain in rational scope at normal use procedure middle pump body rotating speed, stability and the control accuracy of system are improved, pump is large can Feedback medium by opening recirculatory pipe, need not change pump, save time, cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation sketch.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: one makes stable, the accurate device of Small Flow Control, and comprise pump 3, pump 3 input port is communicated with feed tube 2, arranges recirculatory pipe 7, and recirculatory pipe 7 one end is communicated with the output pipe 4 of pump 3, one end connected system pipeline 1 or pumped (conveying) medium source place.The pipeline that recirculatory pipe 7 puts 6 with output pipe 4 connectivity part of pump 3 to user is provided with flowmeter 5.Recirculatory pipe 7 is arranged manual modulation valve 8.Pump 3 is the volume pump of adjustable speed.Recirculatory pipe 7 with realized by threeway being communicated with of output pipe 4 of pump 3.
The utility model adopts can the return line of manual adjustments flow, and make the output medium partial reflux of the system capability interference pump housing in system, a part outputs to use point in addition.The flow using the required medium of point is accurately controlled by the rotating speed of the closed-loop control pump housing.Manual modulation valve on recirculatory pipe, for regulating capacity of returns, can change system performance comparatively neatly, guarantees to remain in rational scope at normal use procedure middle pump body rotating speed, also can improve stability and the control accuracy of system simultaneously.(note: this manual modulation valve is generally fixed on certain aperture after debugging completes does not need to regulate again.）
