Description
Technical field
The present invention relates to a kind of screw pump accessories, and in particular to is easily installed the screw rod of detection device in pumping.
Background technique
Screw pump is to be formed by engage spatial volume variation and movement to convey liquid or be allowed to screw rod by the pump housing
The drum pump of pressurization.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 rotates
When, drive the driven screw engaged to rotate together, the screw rod engagement spatial volume of suction chamber one end is gradually increased, pressure drop
It is low.Liquid enters engagement spatial volume under differential pressure action.As soon as liquid exists when volume increases to maximum and formation seal chamber
One by one continuously along axial movement in seal chamber, until discharge chamber one end.At this moment the screw rod engagement space that chamber one end is discharged holds
Product is gradually reduced, and liquid is discharged.The working principle of screw pump is similar to gear pump, only in structure with screw rod instead of
Gear.The characteristics of table is various screw pumps and application range.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 from damaging as discharge blockage makes the outlet pressure of pump be more than feasible value for some reason
Pump or prime mover.
When screw rod pump work, screw rod moves in pump housing bushing, since screw rod is filled with bushing in the course of work of screw pump
Tap touching installs sensor on the pump housing and is necessarily required to that groove is arranged on the pump housing, necessarily will affect the intensity of the pump housing, therefore,
As a pressure vessel it is difficult that various sensors and detection device are installed in the pump housing.
Summary of the invention
The technical problem to be solved by the present invention is to when screw rod pump work, screw rod moves in pump housing bushing, due to screw rod
Screw rod comes into full contact with bushing in the course of work of pump, and sensor is installed on the pump housing and is necessarily required to that groove is arranged on the pump housing,
It necessarily will affect the intensity of the pump housing, therefore, be difficult that various sensors and detection dress are installed in the pump housing as a pressure vessel
Set, and it is an object of the present invention to provide be easily installed pump in detection device screw rod, solves the problems, such as in pumping of screw pump body installation sensor.
The present invention is achieved through the following technical solutions:
It is easily installed the screw rod of detection device in pumping, including sequentially connected universal shaft, universal axle bed and screw rod, the spiral shell
Bar includes the thin bar for radially-inwardly cutting formation at least one along screw rod, and shape is additionally provided at the thin bar and screw pump serves as a contrast
Matched mounting plate is covered, through-hole is provided on the mounting plate, the thin bar when shape and screw pump of the through-hole work normally
Motion profile is identical.It solves that the groove for installing sensor is arranged on screw pump, most effective method is in installation place
The thickness of stator is thickeied, and the bar diameter of screw rod need to be matched with the stator of thickening after thickening the thickness of stator, at thickening, i.e., the described spiral shell
Bar includes the thin bar for radially-inwardly cutting formation at least one along screw rod, and in order to avoid being dismantled to screw pump, the present invention
Using mounting plate is arranged on screw rod, mounting plate is packed at the covert thickening mounting plate of the method in pumping when installing screw rod
The installation of sensor is realized in sensor installation by stator on a mounting board, meanwhile, carrying out any processing to mounting plate will not shadow
Ring the integral strength for arriving screw pump.
The thin bar is mounted in through-hole.Thin bar is mounted in through-hole, since the shape and screw pump of through-hole work normally
When thin bar motion profile it is identical, therefore work normally when, thin bar can move freely in through-hole and keep the contact with through-hole.
The contact position of the thin bar and through-hole is additionally provided with sealing rubber ring.The effect of sealing rubber ring and screw pump lining
Effect it is identical.
The mounting plate is additionally provided with flow detection groove in the position of through-hole longer end.It is former according to the work of screw pump
Reason, the movement of liquid will necessarily pass through the longer both ends of through-hole.
The mounting plate is additionally provided with screw rod detection groove in the position of through-hole shorter end.Shorter end setting groove can be with
Equipment for installing detection screw rod working condition, under normal circumstances, in a duty cycle, screw rod can be twice by recessed
Slot.
Compared with prior art, the present invention having the following advantages and benefits:
1, the present invention is easily installed the screw rod for pumping interior detection device, can effectively solve and installs sensor inside screw pump
Problem；
2, the present invention is easily installed the screw rod for pumping interior detection device, without being transformed to the pump housing, does not influence pump housing entirety
Intensity, improving cost are low.
