Description

A bearing structure for a water pump in a pump station

Technical Field

The present application relates to the technical field of bearings, and more specifically, to a bearing structure for a water pump in a pump station.

Background Art

Pump station is a device and project that can provide hydraulic power and pneumatic power with a certain pressure and flow. It is a general term for the buildings such as water inlet, water outlet, pump room, etc. of the drainage and irrigation pump station. Water pumps are needed to transport water during the water inlet and outlet process of the pump station. The bearing is the part where the water pump sliding bearing and the shaft contact. It is generally made of wear-resistant materials such as bronze and anti-friction alloy. In special cases, it can be made of wood, plastic or rubber, and the shape is a tile-shaped semi-cylindrical surface.

The document with the prior art announcement number CN210919830U provides a bearing with strong wear resistance. The device is installed on the outer surface of the sliding bearing by setting a friction-reducing layer, a lubricating liquid and a positioning groove. The positioning groove prevents the bearing from rotating and being misaligned. The bearing is fixed by bolts through the connecting holes. During operation, the bearing rubs against the sliding bearing due to the rotation of the sliding bearing. The friction-reducing layer reduces the friction between the bearing and the sliding bearing. The heat generated by the friction is insulated by the high-temperature resistant coating, so that the heat received by the inside of the bearing body is reduced. The friction-reducing layer made of carbon graphite material is used to reduce the friction between the bearing and the sliding bearing, so that the heat generated is reduced. At the same time, the high-temperature resistant coating coated on the outer surface reduces the influence of heat on the bearing, thereby achieving the purpose of improving wear resistance.

Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when installing the water pump bearing, the oil inlet hole on the bearing must be aligned with the oil inlet hole on the bearing seat to oil the bearing. However, when the above-mentioned bearing is in use, it is still impossible to filter the lubricating oil, resulting in that when impurities are mixed in the lubricating oil, the impurities in the lubricating oil cannot be removed, which increases the friction between the bearing and the journal, making the water pump bearing easy to wear and damage during the operation of the pump station water pump, which not only easily causes the service life of the pump station water pump to be reduced, but also reduces the stability of the operation of the pump station water pump.

In view of this, we propose a bearing structure for a water pump in a pumping station.

The lower liquid hole is located directly above the oil filling hole, and the lower liquid hole is connected to the oil filling hole, and the inner diameter of the lower liquid hole is consistent with the inner diameter of the oil filling hole. This bearing structure can facilitate oiling of the half-bearing 3 through the oil filling hole opened on the half-bearing 3, thereby effectively reducing the friction between the bearing and the journal during the operation of the pump station water pump, and when the oiling operation is performed through the oil filling hole on the bearing, the impurities in the liquid lubricating oil flowing into the oil filling hole can be filtered out by the filter assembly, so as to prevent the impurities in the lubricating oil from following the lubricating oil into the space between the half-bearing 3 and the journal, causing wear and damage to the inner wall of the bearing, thereby extending the service life of the bearing, thereby extending the service life of the pump station water pump, and further improving the stability of the operation of the pump station water pump. When it is necessary to add lubricating oil to the oil filling hole, first unscrew the sealing cover body 10 from the internal thread of the opening at the top of the lower liquid hole, and then pull the filter cover 7 upward through the sealing cover body 10.
