Abstract

The utility model proposes a single screw pump rotor, and aims at solving the defects that a hole site of a rotor in the prior art is easily abraded and cannot normally work, and the use cost is increased. The single screw pump motor comprises a rotor, wherein a first universal joint hole site and a second universal joint hole site are arranged on the head of the rotor; the first universal joint hole site is vertical to the second universal joint hole site. The single screw pump rotor is simple in structure, a group of hole sites are processed on the head of the rotor, and the other hole site also can be normally used even if one hole site is abraded, so that high expense of the rotor caused by replacement is avoided.

Description

A kind of helical rotor pump rotor
Technical field
The utility model relates to a kind of rotor, particularly a kind of helical rotor pump rotor.
Background technique
Screw pump is that a kind of pump housing and formed engagement spatial volume of screw rod of relying on changes and the mobile rotary pump of carrying liquid or making it supercharging.
According to the name of industry exercise, the screw rod of helical rotor pump is called to rotor; Rotor is the main rotary component in helical rotor pump.At present, it is generally to realize by the universal swing of pin formula universal joint that the rotor 1A of screw pump does rotation motion, and as shown in Figure 1, this just need to process a pin-and-hole 2A on the connection head of rotor 1A, inserts universal joint pin; Pin stressed larger, can make the pin-and-hole 2A of rotor produce wearing and tearing, if and encase universal joint rubber sheath and damage, lubricant oil in universal joint oozes out, also make the position, hole of rotor easily wear and tear, rotor just can not re-use substantially like this, needs to change, and causes user to lose expensive rotor expense.
Therefore be necessary to design a new helical rotor pump rotor, make up above-mentioned defect.
Model utility content
The utility model proposes a kind of helical rotor pump rotor, thereby solved easily wearing and tearing cisco unity malfunction of position, prior art rotor hole, and increase the defect of user cost.The utility model is simple in structure, and its head position at rotor processes position, one group of hole, even if one of them position, hole produces wearing and tearing, another position, hole can also be used as normally, avoids more exchanging rotor and produces expensive rotor expense.
The technical solution of the utility model is achieved in that
A helical rotor pump rotor, it comprises rotor, the head end of described rotor is equipped with the first universal knothole position and the second universal knothole position, and described the first universal knothole position is mutually vertical with described the second universal knothole position.
Further, in described the first universal knothole position and described the second universal knothole position, be equipped with anti-wearing liner.
Further, described the first universal knothole position and described the second universal knothole position are circle.
The utility model is processed respectively two universal knothole positions by the two ends at rotor, because screw pump is when working, the pin of universal joint and universal knothole position swing back and forth produce stressed, universal knothole position produces wearing and tearing, wherein after universal knothole position wearing and tearing, another universal knothole position can also normally be used, and avoids more exchanging rotor and produces expensive rotor expense.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of prior art helical rotor pump rotor;
Fig. 2 is the structural representation of the utility model helical rotor pump rotor.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of helical rotor pump rotor 1, it comprises rotor 2, the head end of described rotor 2 is equipped with the 3 and second universal knothole position 4, the first universal knothole position, and described the first universal knothole position 3 is mutually vertical with described the second universal knothole position 4.The setting of the utility model first universal knothole position and the second universal knothole position, conveniently by universal joint, rotor is connected to and discharges body and suck on material chamber, the pin-and-hole of universal joint aligns with the first universal knothole position, pin by universal joint passes the pin-and-hole of the first universal knothole position and universal joint simultaneously, thereby rotor and universal joint are fixed.
Further, in described the first universal knothole position and described the second universal knothole position, be equipped with anti-wearing liner (not shown).The setting of anti-wearing liner, all has protective action to the inwall of the inwall of the first universal knothole position and the second universal knothole position, can reduce its wearing and tearing, extends its working life.
Further, described the first universal knothole position and described the second universal knothole position are circle.The shape of the utility model first universal knothole position and the second universal knothole position designs according to the shape of universal joint pin, and those skilled in the art can select other shape as required.
The utility model is processed respectively two universal knothole positions by the head end at rotor, because screw pump is when working, the pin of universal joint and universal knothole position swing back and forth produce stressed, universal knothole position produces wearing and tearing, wherein after universal knothole position wearing and tearing, another universal knothole position can also normally be used, and avoids more exchanging rotor and produces expensive rotor expense.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.

Claims (3)
