Description

Technical Field

[0001] This utility model relates to the field of mud and sand pump technology, and in particular to a new bearing assembly structure for large mud and sand pumps. Background Technology

[0002] The bearing assembly for a slurry pump is a key component specifically designed for slurry pumps. It mainly consists of bearings, seals, and a support structure. It supports the pump shaft and reduces friction during rotation, ensuring smooth operation of the pump when conveying liquids containing solid particles. The bearings are usually made of wear-resistant and corrosion-resistant materials to adapt to harsh working environments. The seals effectively prevent impurities such as mud and sand from entering the bearing, extending the bearing's service life. The overall design focuses on improving pump efficiency and reliability while reducing maintenance requirements.

[0003] The bearing assembly of a mud and sand pump maintains normal operation by periodically adding lubricating oil and natural heat dissipation. However, it is difficult to effectively reduce the temperature of the bearing assembly. Under high load and high temperature environment, the bearing assembly is prone to damage due to overheating, which reduces its service life. Therefore, we propose a new bearing assembly structure for large mud and sand pumps. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a new bearing assembly structure for large-scale mud and sand pumps.

[0005] This utility model is achieved using the following technical solution: a new bearing assembly structure for a large mud and sand pump, including a fixed bushing, two symmetrically arranged bearings fixedly connected to the inner wall of the fixed bushing, sealing end caps fixedly installed at the left and right ends of the fixed bushing, a shaft rotatably connected to the inner wall of the bearings, a first heat sink fixedly connected to the inner wall of the fixed bushing, a second heat sink fixedly connected to the surface of the fixed bushing, a water cooling assembly provided on the outside of the fixed bushing, and an oil injection pipe connected to the inner wall of the fixed bushing, with a sealing cap threadedly connected to the end of the oil injection pipe away from the fixed bushing;

[0006] The water-cooling assembly includes a cooling sleeve, a water storage tank is fixedly connected to the bottom of the cooling sleeve, a protective box is fixedly connected to the front end of the water storage tank, a water pump is fixedly connected to the inner wall of the protective box, a water pump is connected to the bottom of the water pump via a pumping pipe, and a water pump is connected to the top of the water pump via a delivery pipe.

[0007] The above technical solution involves starting a water pump, which draws cooling water from the storage tank through a pumping pipe and then delivers it into the cooling sleeve through a delivery pipe. The cooling water absorbs heat from the surface of the fixed bushing and the second heat sink, achieving a cooling effect. This improves heat dissipation efficiency, reduces wear and damage caused by high temperatures, and extends service life. Two bearings support the shaft, ensuring stability during use. The sealed end cap effectively prevents mud, sand, and water from entering the fixed bushing.

[0008] As a further improvement to the above solution, the inner wall of the cooling sleeve is fixedly connected to the surface of the fixed bushing, and a water outlet hole is provided at the bottom of the cooling sleeve.

[0009] With the above technical solution, when cooling water enters the interior of the cooling sleeve, the cooling water can fully contact the surface of the fixed bushing to dissipate heat.

[0010] As a further improvement to the above solution, the water storage tank is connected to the cooling sleeve through a water outlet.

[0011] Through the above technical solution, the cooling water inside the cooling sleeve flows into the water storage tank through the water outlet, thus achieving recycling.

[0012] As a further improvement to the above solution, the rear end of the water storage tank is connected to a water inlet pipe, and a valve is installed at one end of the water inlet pipe.

[0013] The above technical solution allows cooling water to be easily injected into the water storage tank through the inlet pipe, and the valve allows the inlet pipe to be closed to prevent cooling water from flowing out.

[0014] As a further improvement to the above solution, one end of the water pump extends to the outside of the protective box and is connected to the water storage tank.

[0015] The above technical solution protects the water pump with a protective box, preventing mud and sand from affecting the water pump during use.

[0016] As a further improvement to the above solution, one end of the water supply pipe extends to the outside of the protective box and communicates with the top of the cooling sleeve.

[0017] As a further improvement to the above solution, the number of the first heat sink and the second heat sink are both provided in multiples, with the second heat sink located inside the cooling sleeve.

[0018] The above technical solution allows the heat inside the fixed bushing to be conducted to the surface of the fixed bushing through the first heat sink, and the heat on the surface of the fixed bushing to be absorbed by the second heat sink, which facilitates subsequent heat dissipation through the water cooling component.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention incorporates a water-cooling component. Specifically, by activating a water pump, the pump draws cooling water from the storage tank through a pumping pipe and then delivers it into the cooling sleeve through a delivery pipe. The cooling water absorbs heat from the surface of the fixed bushing and the second heat sink, achieving a cooling effect. This improves heat dissipation efficiency, reduces wear and damage caused by high temperatures, and extends service life.

[0021] This utility model incorporates an oil injection pipe and a sealing cap. Specifically, the oil injection pipe injects lubricating oil into the interior of the fixed bushing to lubricate the bearing, reduce friction, and thus reduce the heat generated by friction. The sealing cap is threadedly connected to the oil injection pipe to seal it and prevent lubricating oil leakage. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-6This embodiment of a new bearing assembly structure for a large-scale mud and sand pump includes a fixed bushing 1, two symmetrically arranged bearings 2 fixedly connected to the inner wall of the fixed bushing 1, sealing end caps 3 fixedly installed at the left and right ends of the fixed bushing 1, a shaft 4 rotatably connected to the inner wall of the bearings 2, a first heat sink 5 fixedly connected to the inner wall of the fixed bushing 1, a second heat sink 6 fixedly connected to the surface of the fixed bushing 1, a water cooling assembly 7 provided on the outside of the fixed bushing 1, an oil injection pipe 8 communicating with the inner wall of the fixed bushing 1, and a sealing cap 9 threadedly connected to the end of the oil injection pipe 8 away from the fixed bushing 1.

[0033] The water-cooled assembly 7 includes a cooling sleeve 701. A water storage tank 702 is fixedly connected to the bottom of the cooling sleeve 701. A protective box 703 is fixedly connected to the front end of the water storage tank 702. A water pump 704 is fixedly connected to the inner wall of the protective box 703. A water pump 704 is connected to the bottom of the water pump 704 via a water suction pipe 705, and a water supply pipe 706 is connected to the top of the water pump 704. Lubricating oil is injected into the interior of the fixed bushing 1 through the oil injection pipe 8 to lubricate the bearing 2, reduce friction, and thus reduce the heat generated by friction. The lubricating oil is then released through the sealing cap 9 and the oil injection pipe 706. The oil pipe 8 is threaded and sealed to prevent lubricating oil leakage. The water pump 704 is started. The water pump 704 draws cooling water from the water storage tank 702 through the water pumping pipe 705 and then sends it into the cooling sleeve 701 through the water delivery pipe 706. The cooling water absorbs the heat from the surface of the fixed bushing 1 and the second heat sink 6, thereby achieving a cooling effect, improving heat dissipation efficiency, reducing wear and damage caused by high temperature, and extending service life. The cooled water returns to the water storage tank 702 through the water outlet.

[0034] The inner wall of the cooling sleeve 701 is fixedly connected to the surface of the fixed bushing 1, and a water outlet is provided at the bottom of the cooling sleeve 701.

[0035] The water storage tank 702 is connected to the cooling sleeve 701 through the water outlet.

[0036] The rear end of the water storage tank 702 is connected to a water inlet pipe, and a valve is installed at one end of the water inlet pipe. The water inlet pipe facilitates the injection of cooling water into the interior of the water storage tank 702 for subsequent cooling.

[0037] One end of the water pump 705 extends to the outside of the protective box 703 and is connected to the water storage tank 702.

[0038] One end of the water supply pipe 706 extends to the outside of the protective box 703 and is connected to the top of the cooling sleeve 701.

[0039] There are several first heat sinks 5 and second heat sinks 6. The second heat sink 6 is located inside the cooling sleeve 701. The heat inside the fixed bushing 1 is conducted to the surface of the fixed bushing 1 through the first heat sink 5, and the heat on the surface of the fixed bushing 1 is absorbed through the second heat sink 6.

[0040] The implementation principle of a new bearing assembly structure for a large-scale mud and sand pump in this application embodiment is as follows: During use, lubricating oil is injected into the interior of the fixed bushing 1 through the oil injection pipe 8 to lubricate the bearing 2, reduce friction, and thus reduce the heat generated by friction. The sealing cap 9 is threadedly connected to the oil injection pipe 8 to seal it and prevent lubricating oil leakage. When the fixed bushing 1 is driven to rotate by an external drive mechanism, it will generate heat through friction with the bearing 2. The heat inside the fixed bushing 1 is conducted to the surface of the fixed bushing 1 through the first heat sink 5, and the heat on the surface of the fixed bushing 1 is absorbed by the second heat sink 6. Then, the water pump 704 is started. The water pump 704 draws cooling water from the water storage tank 702 through the water suction pipe 705, and then sends it into the interior of the cooling sleeve 701 through the water delivery pipe 706. The cooling water absorbs the heat on the surface of the fixed bushing 1 and the second heat sink 6, achieving a cooling effect, thereby improving heat dissipation efficiency, reducing wear and damage caused by high temperature, and extending service life. The cooled water returns to the interior of the water storage tank 702 through the water outlet.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
