The order is one after another, and the performance is booming. The development of Luohe Swire Coca-Cola Beverage Co., Ltd. has been very good in the past few years. But in fact, in the process of production, there are still many problems hindering the further development of enterprises. This is not, as an important part of Coca-Cola online canned, performance of Guangzhou hydraulic system of a UET-230 type injection molding machine Luohe Taigu the latest purchasing is not satisfactory. As the saying goes, rangingand fault injection molding machine hydraulic system affects the whole production efficiency, in the face of such problems, Luohe Swire has taken to?
Luohe is one of the largest in the Pacific Coca-Cola Chinese bottling plant, responsible for the production and sales of Coca-Cola products, its carbonated plastic bottle production line is the most advanced, the highest degree of automation, irrigation, blowing, spinning production line at the same time, the production line of bottled speed is also present in the country in a leading position. But in the production process, responsible for blowing bottle process, Guangzhou UET-230 injection molding machine has the problems of oil blackening and hydraulic system pressure instability.

In order to better complete the Coca-Cola bottling line of compact production tasks, reduce unplanned equipment, Exxon Mobil engineer was invited to help Luohe Taigu analysis the reason of the fault. After field investigation, it is found that the blackening and deterioration of the oil and the instability of the pressure are closely related to the poor oxidation resistance of the hydraulic oil.
Because the hydraulic oil in the extreme environment under high temperature and high pressure, if the poor oxidation resistance of oil, prone to oxidation reaction in the metal catalyst, hydraulic oil hydrocarbons will combine with oxygen heterocyclic form gum products, these products of glioma is what we usually call "sludge", arch-criminal also affect the working efficiency of equipment!
Based on the above reasons, the Mobil Exxon engineers suggested Taigu Luohe repair cooler, it is recommended to use DTE 25 Mobil antiwear hydraulic oil, while providing oil flushing, cleanliness testing, Mobil R and R Shida oil analysis services and personnel training and other services. Under the joint efforts of both sides, the hydraulic oil change cycle is extended to three times of the original, and can save RMB 30000 yuan for enterprises every year!
Exxon Mobil engineers used only simple three measures, let the production equipment "renewal", help Luohe Swire gained 30 thousand yuan a year easily, what use what way, let us see what!
The first one: rinse the hydraulic system thoroughly
Before replacing the new hydraulic oil, the hydraulic system must be thoroughly rinsed to remove the residual sludge in the system components. After washing the system target cleanliness usually set than the normal work of high level, such as the normal operation of NAS grade 8, should be objective cleanliness is set to NAS 6 flushing.
In order to avoid damage to sensitive components in the hydraulic system, fuel tank, filter, cylinder, accumulator, oil pump and motor and other important components must be flush from short circuit or removed, respectively connected to different loop cleaning. At the beginning of rinse, need to check each flushing circuit is connected with the integrity, to ensure that the entire washing system there is no dead / dead, components, pipes and joints all can get the velocity and Reynolds number of specific.

The second trick: replace the appropriate lubrication products
As is known to all, there are two forms of air in hydraulic oil: visible bubbles and invisible dissolved gases. For visible bubbles, with the help of defoaming agents, sufficient time for the oil to be removed will be eliminated. But not visible dissolved gas can not be completely eliminated in the oil, but also with the hydraulic oil into the oil pump, pumping to the high pressure zone of the sliding bearing. The compressed air temperature will rise sharply to 750 DEG C, the hot bubbles will make the hydraulic oil around the high temperature oxidation decomposition, resulting in clay particles, these particles will be suspended in the oil, with oil into the low pressure area, resulting in black oil and system pressure instability etc..
The lubrication condition Mobil DTE 25 antiwear hydraulic oil has excellent antioxidant properties can help to improve the hydraulic system, the balance performance shown by the formula, for precision valves in high pressure and high speed operation, provide reliable anti-wear protection, meet the hydraulic system using high pressure, high output pump, and other components of the hydraulic system as a close clearance servo valve and the demanding needs of CNC machine tools.
The third measure: regular oil analysis, help the operation status monitoring system
In order to further improve the lubricating efficiency of enterprises, to provide a matching Mobil R and R Shida oil analysis service and operator training Mobil Engineer for Luohe Taigu exxon. Comprehensive oil analysis service can provide the necessary data for the enterprise, to help the operator to better understand the running condition of the equipment, understand the effect of equipment running efficiency and productivity of the key points, to help enterprises avoid the non plan of equipment maintenance, maintenance and replacement, protection of production equipment and business enterprises.
