Description

Pump and the tobacco leaf reforging equipment with the pump

Technical field

The technical field of paper process tobacco leaf reconstruction is the utility model is related to, in particular to a kind of pump and there is the pump Tobacco leaf reforging equipment.

Background technology

Pump (such as pulp pump) includes the housing with axis hole, the impeller being rotatably arranged in housing and for driving Wheel rotation is simultaneously located in the axle in axis hole.Axle extends to the outside of housing to connect the motor of transfer tube by axis hole.

Pump also includes the seal member for being used for the gap between seal shaft and axis hole.Seal member includes the first seal member With the second seal member, the first seal member and the second seal member are set on axle and arranged along the bearing of trend of axle.The One seal member is fixed between axle and the inwall of axis hole and relative to housing, the second seal member be located at enclosure interior and with Axle is rotated, and the end face of the end face of the first seal member and the second seal member is abutted against to form sealing structure, the mistake that axle rotates The end face phase mutual friction of Cheng Zhong, the end face of the first seal member and the second seal member and produce frictional heat.

By for example when the concentration for the fluid (such as paper pulp) that pump is pumped is higher, it is close that fluid cannot be used for cooling first Part and the second seal member are sealed, therefore hole is provided with housing, is used to cool down the first seal member and the second sealing to introduce The cooling liquid of part, while the cooling liquid also can form liquid between the first seal member and the second seal member Film, to increase the sealing property of the first seal member and the second seal member.

In the prior art, pump is equipped with the stream of oriented seal member conveying cooling liquid, but stops in the stream to close When sealing part offer cooling liquid, seal member easily damages because temperature is too high.

First valve, is arranged in second flow path, to control the break-make of second flow path；And

Controller, when detection part detects that first flow path stops providing cooling liquid to seal member, open first Valve is so that second flow path provides cooling liquid to seal member.

Alternatively, pump also includes warning piece, and it is cold to seal member offer to detect that first flow path stops in detection part But during liquid, controller makes warning piece alert.

Alternatively, pump also includes being used to drive the motor of wheel rotation, detection part detect first flow path stop to When seal member provides cooling liquid, controller controlled motor reduces rotating speed.

Alternatively, pump also includes timer, for record first flow path stop to seal member provide cooling liquid when Between, if first flow path can not be recovered to provide cooling liquid to seal member in the given time, controller leaves the motor off rotation.

Alternatively, pump also includes：

Fluid reservoir, for providing cooling liquid to second flow path；

3rd stream, for providing cooling liquid to fluid reservoir；And

Second valve, it is arranged in the 3rd stream, it is cold to seal member offer to detect that first flow path stops in detection part But during liquid, controller opens the second valve so that the 3rd stream provides cooling liquid to fluid reservoir.

Alternatively, detection part includes being used for the pressure sensor for detecting the pressure in first flow path.

Alternatively, seal member includes：

First seal member, it is set between the inwall of axis hole and axle and is relatively fixed with housing；

Second seal member, it is set on axle and is rotated with axle, the second seal member is arranged in housing, cooling liquid energy Enough flow between the first seal member and the second seal member, to form liquid film.

According to the another aspect of the application, present invention also provides a kind of tobacco leaf reforging equipment, the tobacco leaf reforging equipment bag Above-mentioned pump is included, the pump is pulp pump, for pumping paper pulp.

Using the technical scheme of the application, when first flow path stops providing cooling liquid to seal member, standby the Second-rate road direction seal member provides cooling liquid, to prevent seal member from being damaged because of overheat.

It is of the present utility model other by referring to the drawings to the detailed description of exemplary embodiment of the present utility model Feature and its advantage will be made apparent from.
