Description
Technical field
The present invention relates to a kind of flow testing device, especially for the proving installation of dust-free paper production line.
Background technology
Dust-free paper is that to adopt wood pulp cellulose be raw material, processes by air lay technology.Its production technology is mainly into net and reinforces two processes, makes fiber be dispersed on forming net taking air as spreading agent, by meldable fibre or the fixing sheet forming of latex.At present in air lay dust-free paper production line, in the time of production applying glue series products, when normal production, the resistance at mixed agency place is 2.5～3bar, if have the top hole pressure of to be less than the pressure of mixed agency in three pumps, the material flow that pump is carried so will not meet manufacturing technique requirent, and sizing applicator applying glue is inhomogeneous and cause that product quality is defective.Original equipment is the output pressure to three pumps of sizing applicator and the flow Static Detection before producing not, if the stator of pump and rotor are produced cycle memory in friction and gap becomes large upper one, do not find in time, upper while once producing, what Gap-Ratios was original exceed 0.05mm all will have influence on the applying glue uniformity coefficient of product, and applying glue inhomogeneous product client do not accept, and all can have the above rejection numbers of tons up to a hundred every year, cause very large waste, also affected the performance of machine itself.Also there are at present some proving installations for pressure and flow, as:
1, " pressure and the flow measurement device " that the patent No. is 200620147496.6, disclosed measurement mechanism is " for determining relative pressure and pressure and flow measurement device according to the definite flow that flows through the fluid of measuring passage of effective pressure principle.This pressure and flow apparatus comprise one have measure on the installed surface that the fluid modules of passage and is removably mounted on fluid modules and comprise that a relative pressure sensor and one are in the computing module of this relevant differential pressure pickup separating ";
2, " flow rate-measuring device " that the patent No. is 200480008763.5, disclosed measurement mechanism " wall at the mobile stream of determined fluid is provided with flow sensor; be provided with the parts with minimum section stream in the downstream of stream sensor, and these parts have minimum section compared with being provided with the section of stream of position of flow sensor ";
These proving installations can gaging pressure and flow, but cannot exert pressure to tested device, cannot be used for applying the test of specified pressure down-off.
Summary of the invention
The invention provides a kind of flow measurement device, when having solved measuring flow, cannot apply the technical matters of specified pressure.
Technical scheme of the present invention is: a kind of air lay dust-free paper production line sizing applicator static tester, comprise front cavity, holder, cylinder pipe, middle cavity, tensimeter, rear chamber, measures entrance, measure outlet, water inlet, water delivering orifice, the overall inside cavity of described front cavity, middle cavity and rear chamber composition seals; Described holder is embedded in the external side of ante-chamber; Described water inlet, water delivering orifice and tensimeter are embedded in the external side of lumen; Described measurement entrance is embedded in holder; Described measurement outlet is embedded in rear chamber outside; Described cylinder pipe is fixed on holder and rear chamber.Described cylinder pipe is pressure changeable element; Described measurement entrance and described measurement outlet, described water inlet and described water delivering orifice are two independently passages.
Described cylinder pipe is made up of nitrile rubber.
Described front cavity and holder adopt and are threaded.
Described front cavity, middle cavity and holder all adopt weldless steel tube turning to be shaped, and described rear chamber adopts steel plate turning moulding.
Described middle cavity is that flange is connected with described rear chamber.
Described cylinder pipe is fixed on holder and rear chamber with piping clip.
Described water inlet, water delivering orifice and tensimeter can be positioned at homonymy also can be positioned at not homonymy.
A kind of air lay dust-free paper of the present invention production line sizing applicator static tester, measures entrance and connects production line outlet to be measured, and measurement exit connects the liquid of outflow with a container; By water inlet to the liquid that injects certain pressure in cavity; the flexible pipeline that adopts pressure changeable element to manufacture is subject to External Force Acting; caliber pressurized diminishes; apply certain pressure to production line outlet to be measured, move the production line regular hour to be measured, after 5 minutes, shut down; stop the liquid weight in rear weighing container; with the weight contrast that flowmeter on sizing applicator production line shows, data differ machine normal operation are described in technique allowed band, otherwise need to keep in repair equipment.Adopt after this device, in the time of production applying glue series products, all can ensure machine normal operation at every turn, the pressure of every pump and flow all reach technological requirement, have greatly reduced rejection number, and economic benefits comparison is obvious.Each test only needs five to ten minutes, does not affect production, the measurement of operating mode and controls, and possesses feature and the advantages such as simple in structure, practical reliable, simple to operate.
