[0003] However, when the pump is running, the bearing is prone to poor lubrication effect. Once the bearing temperature rises too fast, it will seriously affect its service life and lead to the problem of frequent repairs, seriously affecting the safe production of users. Content of the Utility Model

[0004] The purpose of the utility model is to provide a chemical process pump with a lubricating oil system to solve the self-lubrication problem of the chemical process pump.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A chemical process pump with a lubricating oil system, including a bearing suspension and a rotating shaft. An oil slinger is arranged outside the rotating shaft, and an oil slinger ring is installed outside the oil slinger. An oil inlet channel and an oil return channel are arranged in the inner cavity of the bearing suspension.

[0006] Preferably, there are two oil inlet channels and two oil return channels, and the oil inlet channels and the oil return channels are arranged on both sides of the inner cavity of the bearing suspension.

[0007] Preferably, a cross rib is installed in the inner cavity of the bearing suspension, and the two oil inlet channels on both sides are arranged on the upper surface of the cross rib.

[0008] Preferably, the horizontal height of the oil inlet channel is higher than that of the oil return channel.

[0009] Preferably, the oil inlet channel and the oil return channel are connected to the bearing chamber outside the bearing.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By setting the oil slinger and the oil slinger ring installed on the bearing, during the rotation of the bearing, the oil in the bearing suspension is scraped up and flows out along the oil inlet channel to the bearing chamber, increasing the lubricity of the bearing. And through the cooperation of the cross rib, the effect of picking up part of the lubricating oil is achieved, so that more oil can be led to the bearing part along the oil inlet channel, realizing a better lubrication effect. Its overall structure is simple, easy to manufacture, the service life of the bearing is long, the number of repairs is small, the use cost is low, and the safe production of users is more guaranteed.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 2-7 , the present utility model provides a technical solution: a chemical process pump with a lubricating oil system, including a bearing suspension 1 and a rotating shaft 2, and the rotating shaft 2 is connected to the bearing suspension 1 through a bearing 9. The chemical process pump further includes structures such as a pump body, a pump cover, an impeller, a sealing ring, a mechanical seal, a bearing isolator, and a sealing flushing pipeline. The above structures constitute an existing chemical process pump, which will not be elaborated here.

[0022] An oil slinger 3 is provided outside the rotating shaft 2, and an oil thrower ring 4 is installed outside the oil slinger 3. By the self-rotation of the bearing 2, the oil slinger 3 and the oil thrower ring 4 are driven to rotate simultaneously, thereby lifting the oil in the oil chamber of the bearing suspension 1.

[0023] The inner cavity of the bearing suspension 1 is provided with an oil inlet passage 5 and an oil return passage 6. The oil inlet passage 5 and the oil return passage 6 are connected to the bearing chamber 8 outside the bearing 9, so as to lubricate the bearing and return the oil. And the horizontal height of the oil inlet passage 5 is higher than that of the oil return passage 6, ensuring that the lubricated oil can flow to the oil return passage 6 under the action of gravity and flow back to the oil storage inner cavity of the bearing suspension 1 along the oil return passage 6.

[0024] The bearing chamber 8 is specifically a sealed chamber between the outside of the bearing 9 and the inside of the bearing isolator 10, which can store a small amount of lubricating oil. At the same time, the oil inlet passage 5 and the oil return passage 6 are both arranged on both sides of the inner cavity of the bearing suspension 1 and are connected to the bearing chambers 8 on both sides.

[0025] A transverse rib 7 is installed in the inner cavity of the bearing suspension 1, and the oil inlet passages 5 on both sides are opened on the upper surface of the transverse rib 7. In this way, the oil lifted by the oil throwing ring 4 will fall on the upper surface of the transverse rib 7 and flow to the oil inlet passage 5. Since the oil inlet passage 5 is connected to the bearing, the lubrication effect on the bearing can be further ensured.

[0026] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0027] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
