In infrastructure projects, rotary excavators can be regarded as the "main construction force", and their efficient operation directly affects project progress and costs. However, many construction teams have neglected daily maintenance, resulting in frequent equipment failures and skyrocketing maintenance costs. Data shows that rotary excavators lacking standardized maintenance have an average annual maintenance cost more than twice as high as normal maintenance equipment! Mastering the correct maintenance methods can not only prolong the service life of equipment, but also save real money for enterprises. Next, this full process maintenance guide will help you easily avoid the trap of "high maintenance costs".
As the power core of the rotary excavator, the performance of the engine directly determines the efficiency of the equipment. In daily maintenance, oil change is the most basic but easily overlooked step. Many operators, in order to save costs, use engine oil beyond its expiration date, unaware that deteriorated oil will exacerbate internal wear and tear of the engine. It is recommended to change the engine oil strictly according to the prescribed cycle in the equipment manual, and choose the appropriate engine oil model. For example, when working in high-temperature areas, oil with stable high-temperature performance should be selected to avoid poor lubrication caused by a decrease in oil viscosity.
In addition to engine oil, cleaning and replacing the air filter are equally crucial. In dusty construction sites, filters are prone to clogging. If not cleaned or replaced in a timely manner, a large amount of dust will enter the engine with the air, accelerating the wear of components such as pistons and cylinder liners. It is recommended to clean the air filter every 50 hours of work; After working for 500 hours, a new filter must be replaced. In addition, regularly check the tightness and wear of the engine belt. If the belt is loose or cracked, it should be adjusted or replaced immediately, otherwise it may cause problems such as poor engine heat dissipation and power reduction.
