Abstract
The utility model discloses a sealing fin for a single-stage high-speed blower. The sealing fin (1) for the single-stage high-speed blower is of an annular fin body and is arranged between a shaft head (3) of a high-speed shaft of a Roots blower and an oil seal (4) of a speed increasing box. The sealing fin (1) for the single-stage high-speed blower is made from copper. According to the sealing fin for the single-stage high-speed blower, the sealing fin made from copper is arranged between the shaft head of the high-speed shaft and the oil seal of the speed increasing box; enough strength is ensured by the sealing fin for the singe-stage high-speed blower; and even if the sealing fin is in contact with the high-seed shaft by accident, the high-seed shaft is not damaged due to the softness of the copper sealing fin, so that the reliability is high. Besides, according the sealing fin for the single-stage high-speed blower, the installation convenience and the sealing effect are taken into account.
Description
Technical field
The utility model relates to the roots blower technical field, especially a kind of single-stage high-speed blower fan diaphragm seal.
Background technique
Roots blower is in the situation that the high speed shaft High Rotation Speed, can produce powerful vacuum between the oil sealing of the rear of high speed shaft spindle nose and speedup box, because the cause of this vacuum, cause oil leakage phenomenon even if coordinate good oil sealing also can oil be sucked out from the gap of oil sealing and axle because of the impact of negative pressure of vacuum, fan work brings harmful effect again.
Summary of the invention
In order to prevent the generation of this phenomenon, the purpose of this utility model is to provide a kind of single-stage high-speed blower fan diaphragm seal, loads onto diaphragm seal in order to isolated vacuum between the oil sealing of the spindle nose of high speed shaft and speedup box, thereby reaches the purpose that prevents leakage of oil.
The technical solution of the utility model is:
A kind of single-stage high-speed blower fan diaphragm seal, described comprise the single-stage high-speed blower fan with diaphragm seal (1) for circular lamellar body, it is arranged between the oil sealing (4) of the spindle nose (3) of the high speed shaft of roots blower and speedup box.
Described single-stage high-speed blower fan is copper with the material of diaphragm seal (1).
Described single-stage high-speed blower fan is 1.5 to 3 millimeters with the thickness of diaphragm seal (1).The sealing sheet can adopt the copper sheet of 2mm to guarantee enough intensity, contacts with high speed shaft also and can or not shine into infringement to high speed shaft because of copper sheet is softer even shine into diaphragm seal because of unexpected reason.
Described single-stage high-speed blower fan is arranged on high speed shaft (2) with diaphragm seal (1), and the radial fit gap of itself and high speed shaft (2) is 1mm.
In the situation that convenience and sealing effect that consideration is installed are taken into account, described single-stage high-speed blower fan will guarantee more than 10mm with the spacing between diaphragm seal (1) and roots blower spiral case (5).
The beneficial effects of the utility model are:
Single-stage high-speed blower fan of the present utility model adopts the copper diaphragm seal to be arranged between the oil sealing of the spindle nose of high speed shaft and speedup box with diaphragm seal, single-stage high-speed blower fan of the present utility model has guaranteed enough intensity with diaphragm seal, contact with high speed shaft also and can or not shine into infringement to high speed shaft because of copper sheet is softer even shine into diaphragm seal because of unexpected reason, reliability is higher.
Single-stage high-speed blower fan of the present utility model has also been considered the convenience of installation and taking into account of sealing effect with diaphragm seal.
Single-stage high-speed blower fan of the present utility model also has simple in structure, easy to use with diaphragm seal, with the advantage of safeguarding.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 be that high speed shaft, 3 is spiral case for the oil sealing of speedup box, 5 for the spindle nose of high speed shaft, 4 for the single-stage high-speed blower fan with diaphragm seal, 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As Fig. 1, a kind of single-stage high-speed blower fan diaphragm seal, comprise the single-stage high-speed blower fan with diaphragm seal (1) for circular lamellar body, it is arranged between the oil sealing (4) of the spindle nose (3) of the high speed shaft of roots blower and speedup box.
The single-stage high-speed blower fan is copper with the material of diaphragm seal (1).
The single-stage high-speed blower fan is 1.5 to 3 millimeters with the thickness of diaphragm seal (1).The sealing sheet can adopt the copper sheet of 2mm to guarantee enough intensity, contacts with high speed shaft also and can or not shine into infringement to high speed shaft because of copper sheet is softer even shine into diaphragm seal because of unexpected reason.
The single-stage high-speed blower fan is arranged on high speed shaft (2) with diaphragm seal (1), and the radial fit gap of itself and high speed shaft (2) is 1mm.
In the situation that convenience and sealing effect that consideration is installed are taken into account, described single-stage high-speed blower fan will guarantee more than 10mm with the spacing between diaphragm seal (1) and roots blower spiral case (5).
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; various modification and improvement that in related domain, common engineers and technicians make the technical solution of the utility model; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
