The application of centralized lubrication systems in rotary drilling RIGS is inevitable to create greater value for customers

With the increasing demand for infrastructure construction, China has begun to independently research and develop and manufacture pile driving machinery. After nearly 60 years of development, it now has a considerable market scale and brand influence. Whether in terms of the market, enterprises or technology, China's pile driving machinery has gone through a development stage from nothing to something and from weak to strong.

The current situation of lubrication for components of rotary drilling RIGS

In recent years, rotary drilling RIGS, as the leading products of pile driving machinery, have been widely used as the preferred equipment for pile foundation projects in high-rise buildings, highway and railway Bridges, etc., due to their features such as flexible mobility, high construction efficiency, low noise, low pollution and convenient maintenance. Compared with the traditional impact drilling method for hole formation, it has obvious advantages in drilling efficiency, environmental protection, construction quality and economic benefits, and thus has been widely applied.

According to the data statistics of the Pile Driving Machinery Branch of China Construction Machinery Association, the Chinese pile driving machinery industry as a whole was in a stable and progressive development state in 2019. The sales volume of rotary drilling RIGS achieved a year-on-year growth of 9.6% in 2019.

The working environment of rotary drilling RIGS is rather harsh, with heavy dust, water and load. Especially when the entire machine is in operation, the vibration is relatively large. Such a working environment is very unfavorable for the pins and bearings on the entire machine. Therefore, in addition to enhancing the strength of the pin shaft, it is also necessary to lubricate each moving part in a timely and good manner. Currently, the main methods of adding grease to domestic rotary drilling RIGS are manual decentralized injection and centralized injection for lubrication.

When manually adding lubricating oil to a rotary drilling rig, many problems may arise: 1. There are numerous lubrication points on the rotary drilling rig and they are unevenly distributed. Different models have different numbers of lubrication points, and it is difficult to concentrate them together, which brings a lot of inconvenience to manual oiling. 2. The lubrication points are located at a relatively high position. Even if the mast is laid down, the height of some lubrication points is still over 3 meters. Manual addition of lubricating oil requires high-altitude work, and personal safety cannot be guaranteed. 3. Some lubrication points require daily oiling (such as pulley frames and main winches, etc.). Manual addition of lubricating oil wastes time and affects construction. 4. The construction environment is relatively poor, and the work location is not fixed. It is far from auxiliary refueling equipment such as air sources. Most of the time, manual refueling is used, which is both dirty and tiring. 5. Labor costs are increasing year by year, and manual lubricating oil addition does not conform to the trend of automation. 6. It is difficult to add oil in a fixed amount. Each time you add lubricating oil, it all depends on your feeling.

So, what benefits will there be if centralized automatic lubrication is adopted for rotary drilling RIGS? 1. Save labor costs, enhance the level of automation, simplify personnel operation procedures, and reduce the skill requirements for personnel; 2. Safe and convenient; The lubrication pump is set near the chassis, eliminating the need for high-altitude lubricating oil addition operations. It is only necessary to regularly check the operating status of the pump and the integrity of all pipeline joints. 3. Save construction time: Due to the large number of lubrication points of rotary drilling RIGS and their non-concentrated distribution, manual lubrication is time-consuming and laborious. Centralized lubrication only requires regular replenishment of grease to the lubrication pump, which greatly saves lubrication time. 4. It operates reliably and is easy to maintain. If any joint or pipeline is damaged, spare parts can be used to restore it quickly. 5. Forced lubrication can be carried out according to the requirements of each lubrication point, and the lubrication frequency is adjustable.

The application of centralized lubrication in rotary drilling RIGS has achieved remarkable results, reducing the downtime for equipment maintenance and enabling timely maintenance of the equipment, effectively lowering the wear between various rotating components. According to statistics, compared with traditional manual lubrication, centralized lubrication can reduce bearing failure by more than 40%. In addition, it can also save maintenance costs and parts costs. In conclusion, the application of centralized lubrication systems in rotary drilling RIGS plays a significant role in enhancing the service life and performance of the machinery.

To sum up, at present, rotary drilling rig products have gradually begun to adopt centralized lubrication systems.

Sany rotary drilling RIGS have joined hands with Aote Technology for centralized lubrication systems

In December 2019, the Sany rotary drilling rig, which was awarded the title of "Single Champion Product in Manufacturing Industry" by the Ministry of Industry and Information Technology of the People's Republic of China, has become a pioneer. In 2019, over 500 Sany rotary drilling RIGS were equipped with the Aote centralized lubrication system. This year, Sany rotary drilling RIGS will be standard with this product.

Sany rotary drilling RIGS lead in domestic sales. During the usage process, a considerable number of customers have application demands for centralized lubrication systems. Sany initially adopted foreign products but failed to solve the problem after trial use. Later, it cooperated with Zhengzhou Aote Technology, a well-known brand of centralized lubrication, and equipped some rotary drilling RIGS with Aote's dual-line - progressive centralized lubrication system. This part of the product has solved the problem of cumbersome manual maintenance and upkeep during the customer's construction process, significantly reducing the downtime of the equipment, steadily improving efficiency, and notably increasing profits. In terms of both reliability and stability, users generally give excellent feedback.

Zhengzhou Aote Technology Co., Ltd. is a globally leading brand of centralized lubrication solutions. Whether it is wind power lubrication equipment, construction machinery lubrication equipment, or commercial vehicle and large-scale machinery lubrication equipment, Aote Technology can provide customers with globally leading lubrication equipment solutions to meet their needs for equipment lubrication and health management. Its centralized lubrication system, with its advantages of convenient oiling, forced lubrication, extended equipment service life, increased equipment available time, saved grease, and reduced maintenance costs, has been increasingly applied in various construction machinery such as excavators, loaders, motor graders, and rotary drilling RIGS.

In response to the lubrication requirements of rotary drilling RIGS, Zhengzhou Aote Technology Co., Ltd. has independently developed a centralized lubrication system and a full life cycle management Aote centralized lubrication system.

Lubrication system solution for large rotary drilling RIGS

The dual-line centralized lubrication system mainly consists of dual-line pumps, dual-line distributors, progressive distributors and pipeline bundles, etc. At the end of the dual-line distributor, an oil pressure sensor is installed to detect the operation status of the dual-line distributor. At each metering piston of the dual-line distributor, a Hall sensor is set to monitor the operation status of the progressive distributor. The operation status of the entire two-line progressive lubrication system is monitored through oil pressure sensors and Hall sensors.
