Description
Technical field
The present invention relates to a kind of screw pump, and in particular to the screw pump conveyed for gluing fluid pipeline.
Background technology
Screw pump is volume type rotor pump, and it is to change to suck by the volume of the annular seal space formed by screw and bushing
With discharge liquid.Screw pump by screw rod number be divided into single-screw (single screw) pump, it is double, three and five-screw pump.The characteristics of screw pump is flow
Steadily, pressure fluctuation is small, have low suction capacity, noise, efficiency high, long lifespan, reliable operation；And its advantage protruded is conveying
Vortex is not formed during medium, to the sticky insensitive of medium, can transfer of highly viscous medium.Screw pump is by the pump housing and screw rod institute
The engagement spatial volume change of formation and the mobile drum pump to convey liquid or be allowed to supercharging.Screw pump is divided into by screw rod number
Single-screw (single screw) pump, Quimby pump and three screw pump etc..When driving screw rod is rotated, the driven screw engaged is driven to turn together
Dynamic, the screw rod engagement spatial volume of suction chamber one end gradually increases, pressure reduction.Liquid enters engagement space under differential pressure action
Volume.When volume increase to it is maximum and when forming an annular seal space, liquid just in annular seal space one by one continuously along axial movement,
Until discharge chamber one end.At this moment the screw rod engagement spatial volume of discharge chamber one end is gradually reduced, and liquid is discharged.Screw pump
Operation principle is similar to gear pump, simply instead of gear with screw rod in structure.The characteristics of table is various screw pumps and application
Scope.The flow and pressure pulse very little of screw pump, noise and vibration are small, there is suction capacity, but screw rod processing is more difficult.Pump has
Two kinds of structures of single-suction and double-suction type, but single-screw (single screw) pump only has single-suction.Pump must wear safety valve, to prevent because certain is former
Pump or prime mover are damaged because such as discharge blockage makes the outlet pressure of pump exceed feasible value.
Because screw pump is most suitable for suction thick liquid, and thick liquid easily solidifies when temperature is relatively low, is difficult suction,
And suction easily causes damage to the screw pump pump housing by force, and when being heated using heater to screw pump, due to screw pump sheet
Body is metalwork, and heat losses are very fast.
The content of the invention
The technical problems to be solved by the invention are due to that screw pump is most suitable for suction thick liquid, and thick liquid is in temperature
Easily solidified when spending relatively low, be difficult suction, and suction easily causes damage to the screw pump pump housing by force, and use heater pair
When screw pump is heated, because screw pump is metalwork in itself, heat losses are very fast, it is therefore intended that provide for gluing fluid pipeline
The screw pump of conveying, is solved because screw pump is most suitable for suction thick liquid, and thick liquid easily solidifies when temperature is relatively low,
Suction is difficult, and suction easily causes damage to the screw pump pump housing by force, and when being heated using heater to screw pump, due to
Screw pump is metalwork, the problem of heat losses are very fast in itself.
The present invention is achieved through the following technical solutions：
The screw pump conveyed for gluing fluid pipeline, including screw pump, are also nested with outside the outer wall of the screw pump
One layer of heat preservation layer is also nested with outside one layer of electrothermal layer, the electrothermal layer, the heat-insulation layer is hollow-core construction.Electrothermal layer is arranged on
Outside outer wall, the method for setting one layer of heat preservation layer again outside zone of heating makes the heat of electrothermal layer effectively act on screw pump, subtracted
It is few because directly with air contact and the heat that loses.
It is additionally provided with two water filling ports being connected with heat-insulation layer cavity, one of water filling port and connects on the heat-insulation layer
There is water pump.During due to using screw pump at a normal temperature, screw pump needs radiating, and the hollow insulating layer used is unfavorable for dissipating
Heat, therefore, using said structure, can improve radiating efficiency by way of the water filling into heat-insulation layer.
It is additionally provided with the screw rod of the screw pump on speed probe, the speed probe, water pump and electrothermal layer also
It is connected with processor.Processor determines the need for entering screw pump by receiving the screw speed signal that speed probe is sent
Row heating, when needing heating, processor sends output current to electrothermal layer, while controlling water pump to take out the water in heat-insulation layer
Go out.
The electrothermal layer is used sets heating wire to be formed in copper coin.
The present invention compared with prior art, has the following advantages and advantages：
1st, the screw pump that the present invention is conveyed for gluing fluid pipeline, the heat effectively reduced when being heated to screw pump
The loss of amount, environmental protection and energy saving；
2nd, the present invention for gluing fluid pipeline convey screw pump, automatically control, it is simple to operate, screw rod revolution speed compared with
Automatic start when low.
