Description
Technical field
The utility model relates to a kind of screw rod more particularly to a kind of screw pump new screws.
Background technique
Screw pump is volume type rotor pump, it is to change by the volume of the seal chamber formed by screw and bushing to suck
With discharge liquid, in certain occasions, when as more sticky such as liquid, the viscosity of especially liquid is affected by temperature bigger
When, in order to guarantee that screw pump normally conveys liquid, need to carry out heating and thermal insulation to the liquid in screw pump.But current screw rod
Pumping heating and thermal insulation structure, usually structure is complicated, and the cost for manufacturing and safeguarding is caused to increase considerably.
Utility model content
The utility model proposes that a kind of screw pump new screw, the screw pump are added with screw rod aiming at the above problem
Thermal effect is good, and structure is simple, be conducive to maintenance, while manufacturing cost it is low.
In order to solve the above technical problems, a kind of screw pump new screw provided by the utility model, including a rotation axis,
It further include the hollow stem that an inside is circumferentially with screw rod tooth equipped with cavity, outer end, the hollow stem is run through in the rotation axis front end,
The front end of rotation axis is set to be pierced by front end 2-4 centimeters of hollow stem；The rotation axis is equipped with one laterally close to hollow stem front position
Perforation, at the same the hollow stem rear end thereof be connected with one can make heating oil inside hollow stem and rotation axis outer loop plus
Hot oil circulating device.
Preferably as the utility model, the heating oil circulation device includes a round base, outside the round base
Side be equipped with can include with the rotation anchor ring that forms rotation connection on the inside of the hollow stem, the round base oil outlet chamber and
One oil back chamber, is equipped with circulating pump between the oil outlet chamber and oil back chamber, the oil outlet chamber front end is equipped with oil outlet, the oil back chamber
Front end is equipped with oil return opening；Meanwhile the round base rear end is welded with extension rod identical with the rear end diameter of the rotation axis.
The utility model, which is used, is arranged hot-oil circulation channel and in screw pump with hot oil circulating device auxiliary heating
Structure is not only further improved the heating effect of screw pump, and structure is simple, easy to maintain, manufacturing cost also compared with
It is low.
Detailed description of the invention
Shown in FIG. 1 is the appearance assumption diagram of the utility model.
Wherein: 1, rotation axis；2, cavity；3, screw rod tooth；4, hollow stem；5, cross-perforating；6, round base；7, swivel becket
Face；8, oil outlet chamber；9, oil back chamber；10, circulating pump；11, oil outlet；12, oil return opening；13, extension rod.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of screw pump new screw, including a rotation axis 1 further include that an inside is equipped with cavity 2, outer
End is circumferentially with the hollow stem 4 of screw rod tooth 3.
In above structure, hollow stem 4 is run through in 1 front end of rotation axis, and the front end of rotation axis 1 is made to be pierced by the front end 2-4 of hollow stem 4
Centimetre；Rotation axis 1 is equipped with a cross-perforating 5 close to 4 front position of hollow stem, while being connected in the rear end thereof of hollow stem 4
One can make heating oil in the heating oil circulation device of 4 inside and 1 outer loop of rotation axis of hollow stem.
In the present invention, preferably heating oil circulation device includes a round base 6, is set on the outside of the round base 6
Having can include an oil outlet chamber 8 and an oil back chamber 9 with the rotation anchor ring 7 that forms rotation connection on the inside of hollow stem 4, round base 6, out
It is equipped with circulating pump 10 between oil pocket 8 and oil back chamber 9, is equipped with oil outlet 11 in 8 front end of oil outlet chamber, is equipped with back in 9 front end of oil back chamber
Hydraulic fluid port 12；Meanwhile extension rod 13 identical with the rear end diameter of rotation axis 1 is welded in 6 rear end of round base.
During round base 6 is rotated together in company with rotation axis 1, hot oil is pumped out from oil outlet 11 and is entered in hollow stem 4,
Come back to hot oil in oil back chamber 9 by cross-perforating 5, so as to form one recycle, thus reach heating rotation axis 1 and
The purpose of hollow stem 4.
Generally speaking, the utility model is used is arranged hot-oil circulation channel and auxiliary with hot oil circulating device in screw pump
The structure of heating is helped, is not only further improved the heating effect of screw pump, and structure is simple, easy to maintain, manufacture
Cost is relatively low.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into modification.
