Description

Technical Field

[0001] The present application relates to the technical field of bearing boxes, and in particular to a respirator and a bearing box. Background Art

[0002] There are a large number of rotating or stationary equipment in nuclear power plants. In order to ensure the normal operation of the rotating parts, bearing oil tanks with lubricating oil inside are configured for lubrication and cooling. The evaporation of lubricating oil in the bearing box of the pump will increase the internal pressure and affect the normal flow of lubricating oil. Therefore, the bearing box is usually equipped with a breathing valve, which can connect the bearing box with the atmosphere to balance the pressure difference between the inside and outside of the shell. The bearing box generates a large amount of oil and gas during operation, which is cooled into oil droplets in the breather and flows back to the bearing box.

[0003] However, the current respirator condensation section is not long enough, so that the oil and gas cannot flow back into the bearing chamber smoothly, which eventually causes the oil and gas to leak from the respirator.

[0004] Therefore, how to reduce the probability of oil and gas leakage from the respirator is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In view of the above problems, the present application provides a respirator that can effectively reduce the probability of oil and gas leakage from the respirator.

[0006] The specific plan is as follows:

[0007] The first aspect of the present application provides a respirator, comprising a respirator body, a cover body and a partition plate, wherein one end of the respirator body is connected to a bearing box, and the other end is cooperatively connected to the cover body, and there is a gap between the respirator body and the cover body that is connected to the atmosphere, and a partition plate is also arranged in the respirator body, and a reflux hole for oil and gas reflux is opened on the partition plate.

[0008] In a possible embodiment, the respirator body includes a respirator head and a connecting pipe, and the respirator head is connected to the connecting pipe;

[0011] In a possible embodiment, the partition plate includes at least a first partition plate and a second partition plate, the first partition plate is arranged at a middle position of the breathing head, and the second partition plate is arranged at a bottom position of the breathing head.

[0012] In a possible embodiment, the reflow holes include first reflow holes and second reflow holes, the first reflow holes are distributed along the circumference of the first spacer plate, and the second reflow holes are distributed along the circumference of the second spacer plate.

[0013] In a possible embodiment, there are a plurality of the first return holes and a plurality of the second return holes.

[0014] In a possible embodiment, the first partition plate is a circular structure adapted to the inner cavity of the breathing head, and the first partition plate is connected to the inner wall of the breathing head.

[0015] In a possible embodiment, the second partition plate includes a second partition plate body and a connecting plate, wherein one side of the connecting plate is connected to the inner wall of the cavity of the respirator, and the other side of the connecting plate is connected to the second partition plate body;

[0016] The first partition plate is arranged in parallel with the second partition plate.

[0017] In a possible embodiment, a connection assembly is further included, and the respirator body and the cover body are connected by the connection assembly.
