Description
Technical field
It the utility model is related to a kind of screw pump, and in particular to the screw rod for avoiding thick liquid from solidifying by heating the pump housing
Pump.
Background technology
Screw pump is volume type rotor pump, and it is to change by the volume of the annular seal space formed by screw and bushing to suck
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, has low suction capacity, noise, efficiency high, long lifespan, reliable operation；And the advantages of its protrusion 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 of formation changes and moved to convey liquid or be allowed to the drum pump being pressurized.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 rotates, the driven screw engaged is driven to turn together
Dynamic, the screw rod engagement spatial volume of suction chamber one end gradually increases, and pressure reduces.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 one by one in annular seal space continuously along axial movement,
Until discharge chamber one end.At this moment the screw rod engagement spatial volume for discharging 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 with small vibration, 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 not easy suction,
And suction easily causes to damage to the screw pump pump housing by force, and using heater screw pump is heated when, due to screw pump sheet
Body is metalwork, and heat losses are very fast.
Utility model content
Technical problem to be solved in the utility model is due to that screw pump is most suitable for suction thick liquid, and thick liquid
Easily solidified when temperature is relatively low, be not easy suction, and suction easily causes to damage to the screw pump pump housing by force, and use heating dress
Put when being heated to screw pump, because screw pump is metalwork in itself, heat losses are very fast, and it is an object of the present invention to provide by heating the pump housing
The screw pump for avoiding thick liquid from solidifying, solve because screw pump is most suitable for suction thick liquid, and thick liquid temperature compared with
Easily solidified when low, be not easy suction, and suction easily causes to damage to the screw pump pump housing by force, and heater is used to screw rod
When pump heats, due to the problem of screw pump is metalwork in itself, and heat losses are very fast.
The utility model is achieved through the following technical solutions：
The screw pump for avoiding thick liquid from solidifying by heating the pump housing, including screw pump, outside the outer wall of the screw pump
One layer of electrothermal layer is also nested with, is also nested with one layer of heat preservation layer outside the electrothermal layer, the heat-insulation layer is hollow-core construction.By electric heating
Layer is arranged on outside outer wall, the method for setting one layer of heat preservation layer again outside zone of heating, the heat of electrothermal layer is effectively acted on spiral shell
On bar pump, reduce because directly with air contact and the heat that loses.
Two water filling ports being connected with heat-insulation layer cavity are additionally provided with the heat-insulation layer, are connected on one of water filling port
There is water pump.During due to using screw pump at a normal temperature, screw pump needs to radiate, and the hollow insulating layer used is unfavorable for dissipating
Heat, therefore, using said structure, radiating efficiency can be improved by way of the water filling into heat-insulation layer.
Speed probe is additionally provided with the screw rod of the screw pump, is gone back on the speed probe, water pump and electrothermal layer
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 controls water pump to take out the water in heat-insulation layer
Go out.
The electrothermal layer uses sets heating wire to be formed in copper coin.
The utility model compared with prior art, has the following advantages and advantages：
1st, the screw pump that the utility model avoids thick liquid from solidifying by heating the pump housing, when being heated to screw pump
The loss of the heat effectively reduced, environmental protection and energy saving；
2nd, the screw pump that the utility model avoids thick liquid from solidifying by heating the pump housing, is automatically controlled, simple to operate,
Automatic start when screw rod revolution speed is relatively low.
