Description
Technical field
The utility model is related to a kind of screw pump accessory, and in particular to the screw rod of screw pump with heating arrangement.
Background technology
Screw pump is that the spatial volume that engages for relying on the pump housing and screw rod to be formed changes and moves to convey liquid or be allowed to
The drum pump of supercharging.Screw pump is divided into single-screw (single screw) pump, Quimby pump and three screw pump etc. by screw rod number.When driving screw rod is rotated
When, drive the driven screw engaged to rotate together, the screw rod engagement spatial volume of suction chamber one end gradually increases, pressure drop
It is low.Liquid enters engagement spatial volume under differential pressure action.When volume increases to maximum and forms an annular seal space, liquid just exists
One by one continuously along axial movement in annular seal space, until discharge chamber one end.At this moment the screw rod engagement space of discharge chamber one end holds
Product is gradually reduced, and liquid is discharged.The operation principle of screw pump is similar to gear pump, simply be instead of in structure with screw rod
Gear.The characteristics of table is various screw pumps and application.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 for some reason as discharge blockage makes the outlet pressure of pump be damaged more than feasible value
Pump or prime mover.
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.
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 difficult suction, and suction easily causes damage to the screw pump pump housing by force, it is therefore intended that provide
Screw rod of screw pump with heating arrangement, the problem of solving to keep screw pump suction fluid temperature.
The utility model is achieved through the following technical solutions：
Screw rod of screw pump with heating arrangement, including universal drive shaft, universal axle bed and the screw rod being sequentially connected, from universal axle bed
Punched with the junction of screw rod to screw rod bearing of trend, and heating wire be set in hole, the heating wire through universal axle bed with
Electric heating interface connection on universal axle bed.Method by setting heating wire in screw rod, when environment temperature is too low, connects electricity
The power supply of hot interface, heating wire work, heating spiral rod, so that the liquid in heating spiral rod pump, it is ensured that the temperature of liquid.
Insulating heat-conduction material is provided between the heating wire and screw rod.Because heating wire is powered, and screw pump is in itself
It is metallic conductor, security incident is easily caused when heating wire leaks electricity, therefore, one layer of insulating heat-conductive material is further added by outside heating wire
Material can improve security.
The hollow pore of 2n bars that are identical with heating wire track but not contacted with heating wire is additionally provided with the screw rod, n is
Positive integer.By setting hollow pore to reduce the overall weight of screw rod in screw rod, because electric calorifie installation ensure that the pump housing
The temperature of interior liquid, therefore power during whole screw pump normal work suction same liquid also reduces, to all parts
Intensity requirement also has reduction, it is therefore possible to use hollow object is used as screw rod.
It is connected with each other between the hollow pore of 2n bars, and the hollow pore of 2n bars passes through universal axle bed respectively with entering water
Mouth and delivery port connection.Realized by the method for the water filling in hollow pore and the auxiliary in the pump housing is heated or cooled.
The hollow pore of 2n bars is connected with water inlet and delivery port respectively through universal axle bed, wherein the hollow pore of n bars
Connect water inlet, the hollow pore connection delivery port of n bars.Ensure that the flow velocity of water inlet and delivery port is stablized relatively, the stability of a system
It is high.
The utility model compared with prior art, has the following advantages and advantages：
1st, screw rod of screw pump of the utility model with heating arrangement, can keep the temperature of liquid in the pump housing, it is to avoid liquid coagulates
Gu；
2nd, screw rod of screw pump of the utility model with heating arrangement, can be with auxiliary temperature-reducing or heating with water cooled pipeline.
