Special crane

Circular crane for power plants

The nuclear power plant ring crane (referred to as the nuclear ring crane) is a special bridge crane installed on the circular track above the nuclear island reactor building of the nuclear power plant, serving the entire construction, operation, and retirement cycle of the nuclear power plant. It is one of the important equipment of the nuclear power plant. The safe operation of nuclear ring cranes is crucial for ensuring the safety and production of nuclear power plants. The frequent occurrence of earthquakes is an important factor affecting the safety of nuclear ring cranes. Therefore, in the design specifications, it is required that nuclear ring cranes should have good seismic performance. However, with the continuous development of nuclear power technology, traditional design methods for nuclear ring cranes are no longer able to meet seismic requirements, so new design methods are needed to improve the seismic performance of nuclear ring cranes. At present, a simple and effective method is to use shock-absorbing devices to reduce the seismic load on the nuclear ring crane structure, thereby improving the seismic performance of the nuclear ring crane.At present, there is relatively little research on using shock absorption devices to improve seismic performance of nuclear ring cranes, especially for vertical shock absorption devices, which are almost non-existent. Based on the design characteristics of the nuclear ring crane structure, this article designs a new type of shock-absorbing device to improve the seismic performance of the nuclear ring crane without affecting its normal operation.

The single beam bridge crane has compact dimensions, low static height of the building, light self weight, and small wheel pressure. Widely used in industrial and mining enterprises, warehouses, mechanical processing workshops, metallurgical plant auxiliary workshops, material yards, power stations, etc. for transportation, assembly, maintenance, and loading and unloading operations, it can also replace ordinary double beam bridge cranes and be used in production workshops in the light textile industry and instrument industry. His work level is light and intermediate.The product is a type of crane developed in recent years based on the LDA electric single beam crane according to the needs of the market and users.Compared with the ordinary LDA electric single beam crane, this type of product has two independent operating electric hoists. These two electric hoists can independently complete the lifting work of the workpiece and cooperate with each other to complete the flipping of the large workpiece. At the same time, each operating handle can independently control the shared crane operating mechanism, and the price is only slightly increased compared to the ordinary LDA electric single beam crane. Therefore, it is an economical new type of lifting machinery.The commonly used lifting capacity is 1-25t, with a span of 7.5m-22.5m, using a three-phase 380V, 50Hz power supply, and working environment temperature of -25 ℃ -40 ℃. It can also be designed separately according to user requirements.

Reasons and treatment methods for oil leakage in the reducer of electric hoist crane

2024-03-29

Reasons for gearbox oil leakage1. Pressure difference between the inside and outside of the reducer: During the operation of the reducer, the friction and heating of the moving pair, as well as the influence of environmental temperature, cause the temperature of the reducer to increase. If there are no ventilation holes or the ventilation holes are blocked, the pressure inside the reducer gradually increases. The higher the temperature inside the reducer, the greater the pressure difference with the outside world. Under the pressure difference, lubricating oil leaks out from the gaps.2. The structural design of the reducer is unreasonable.1) The inspection hole cover plate is too thin, and after tightening the bolts, it is prone to deformation, causing uneven joint surfaces and oil leakage from the contact gaps;2) During the manufacturing process of the gearbox, if the castings are not annealed or aged, and internal stresses are not eliminated, deformation will inevitably occur, resulting in gaps and leakage;3) There is no oil return groove on the box, and lubricating oil accumulates in the shaft seal, end cover, joint surface, etc. Under the pressure difference, it leaks outward from the gap;4) The design of the shaft seal structure is unreasonable. Early reducers often used oil groove and felt ring type shaft seal structures, which caused deformation of the felt during assembly and sealed the gaps on the joint surface. If the contact between the shaft neck and the seal is not ideal, due to the poor compensation performance of the felt, the seal will fail in a short period of time. Although there are oil return holes on the oil ditch, they are easily blocked and the oil return effect is difficult to exert.3. Excessive refueling: During the operation of the gearbox, the oil pool is stirred violently, and lubricating oil splashes everywhere inside the machine. If the refueling amount is too much, a large amount of lubricating oil accumulates in the shaft seal, joint surface, etc., leading to leakage.4. Improper maintenance process: During equipment maintenance, oil leakage can also occur due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of sealing components, and failure to replace sealing components in a timely manner.
