Description

Technical Field

[0001] The utility model belongs to the technical field of liquid ring pumps, in particular to a bearing frame of a liquid ring pump. Background Art

[0002] The connection between the existing liquid ring pump bearing frame and the bearing is called the bearing seat cavity. The outer circumference of the bearing seat cavity is circular. When installing a temperature or vibration sensor probe with a threaded joint or a magnetic suction, it is necessary to flatten a platform on the outer circle of the bearing seat cavity, and then drill holes according to actual needs. The problem is that it is not easy to position the holes when flattening the outer circle, and the processing is difficult. In addition, if the diameter of the temperature or vibration sensor probe is large, it will be supported by the outer circumference of the bearing cover next to it during installation, resulting in a failure to install smoothly. Summary of the invention

[0003] In order to overcome the defects of the above-mentioned prior art, the utility model proposes a liquid ring pump bearing frame, which can be directly countersunk or drilled on the boss, is easy to position, has low processing difficulty, and will not be blocked by the bearing gland and cannot be installed in place when installing a temperature or vibration sensor probe with a larger diameter. The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0004] A liquid ring pump bearing frame comprises a bearing seat cavity and a base plate, wherein the base plate is fixedly connected to the bearing seat cavity through a supporting body, a boss is arranged on the outer circle of the bearing seat cavity, the number of the bosses is 2-12, the bosses are integrally formed with the bearing seat cavity, and the upper end surface of the bosses is a plane.

[0005] Furthermore, the height of the boss is 1 mm-50 mm.

[0006] Furthermore, the height of the bosses located above and below the bearing seat cavity is 10 mm-50 mm.

[0007] Furthermore, the height of the bosses located at other positions of the bearing seat cavity is 1mm-20mm.

[0008] Specifically, a screw hole is provided at the center of the upper end surface of the boss.

[0009] The utility model can directly countersink or drill holes on the boss, which is easy to position and has low processing difficulty. When installing a temperature or vibration sensor probe with a larger diameter, it will not be blocked by the bearing cover and cannot be installed in place. The boss also plays the role of a reinforcing rib, which can play a certain role in improving the strength of the bearing cavity. In addition, a hole can be drilled into the bearing cavity through the boss and used as a channel for adding and draining grease, thereby significantly improving the overall applicability of the bearing frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model;

[0011] Figure 2 for Figure 1 Front view of . DETAILED DESCRIPTION

[0012] Figure 1 It is a structural schematic diagram of the utility model. Figure 2 for Figure 1 The front view of Figure 1 and Figure 2 As shown, a liquid ring pump bearing frame includes a bearing seat cavity 1 and a base plate 2. The base plate 2 is fixedly connected to the bearing seat cavity 1 through a support body 3. A boss 4 is arranged on the outer circle of the bearing seat cavity 1. The number of the bosses 4 is 2-12. The bosses 4 are integrally formed with the bearing seat cavity 1, and the upper end surface 4.1 of the bosses 4 is a plane.

[0013] The height of the boss 4 is 1mm-50mm, and a screw hole 4.2 is set at the center of the upper end surface of the boss 4. The flat boss 4 can be directly countersunk or drilled, which makes positioning easier, significantly reduces the difficulty of processing, and facilitates the installation of the sensor probe. In order to improve the plane accuracy of the platform, usually one surface is countersunk on the upper end surface 4.1 of the boss 4 and then a hole is drilled. The countersunk surface can be a circular plane according to the diameter of the sensor. The outer edge of the circular plane in this embodiment protrudes outward a little, and the entire upper end surface 4.1 of the boss 4 can also be countersunk so that it will not protrude outward.

[0014] The height of the bosses above and below the bearing seat cavity is 10mm-50mm, and the height of the bosses at other positions of the bearing seat cavity is 1mm-20mm. The boss 4 can also act as a reinforcing rib, which can play a certain role in improving the strength of the bearing frame. In addition, a hole can be drilled into the bearing cavity through the boss 4 to be used as a channel for adding and draining grease.

[0015] The number of bosses 4 in this embodiment is 6. The bosses 4 are higher than the outer circumference of the bearing seat cavity 1. The bosses located above and below the bearing seat cavity are 15 mm high, and the bosses at other positions are 5 mm high. When installing a temperature or vibration sensor probe with a larger diameter, it will not be blocked by the bearing cover and cannot be installed in place; and a grease adding channel 4.3 and a grease draining channel 4.4 are provided.

[0016] In short, the utility model can countersink or drill holes directly on the boss, which is easy to position and has low processing difficulty. When installing a temperature or vibration sensor probe with a larger diameter, it will not be blocked by the bearing cover and cannot be installed in place; and the boss also plays the role of a reinforcing rib, which can play a certain role in improving the strength of the bearing cavity. In addition, a hole can be drilled into the bearing cavity through the boss and used as a channel for adding and draining grease, and the overall applicability of the bearing frame is significantly improved.
