There are some ground mechanical equipment, screw pump oil production system, the system has a wide range of applications, with good versatility, the main working principle is to use the rotation of the rod to drive the movement of the rod, through the linkage of the rod to achieve the work of the entire system. Smooth rod dynamic seal is the main sealing method of the system, but in the actual use of the process, it is very easy to cause environmental pollution, and fault maintenance is difficult. In order to effectively solve such problems, the hydraulic sealing technology can be improved, such as the smooth rod seal combination, the bushing is installed at the position of the smooth rod seal, and two dynamic pressure sealing rings are used to play a lubricating role. This can not only reduce the impact on the environment, strengthen the sealing effect and performance of petroleum machinery, but also improve the economic benefits of petroleum enterprises to a certain extent.
1. Standardize the mechanical operation process
In the actual use of petroleum machinery equipment, the staff needs to adjust the equipment parameters according to the corresponding operation instructions and the actual situation. If the operation is improper or the adjustment is wrong, the normal use of the equipment will be affected, and even serious safety accidents will occur, threatening personal safety and economic benefits. Therefore, in order to avoid such problems, operators should undergo targeted training before working, practice to master the use of equipment operation instructions, to ensure that there will be no mistakes or violent operations in the operation process. By reasonably standardizing the operation process of petroleum machinery equipment, the internal system of mechanical equipment can be guaranteed and the service life of equipment can be extended. In addition, when using hydraulic sealing technology, it is also necessary to scientifically select the amount of hydraulic oil and internal gas volume according to the actual situation to avoid equipment damage caused by improper dosage.
2, scientific selection of hydraulic medium
The main medium in the hydraulic system of petroleum machinery equipment is hydraulic oil, whose role is to improve the softening and sealing degree of equipment operation, and can also really grab the efficacy of transmission. The different type of hydraulic oil will have different effects with the hydraulic system, if the hydraulic oil is improperly selected, it will affect the safe operation of the entire hydraulic system, and the long-term use of inappropriate hydraulic oil, the entire equipment is likely to be damaged, affecting the safety of use. Therefore, in the process of using petroleum machinery and equipment, the relevant staff should choose the hydraulic mechanism reasonably and scientifically according to the instructions for the use of the equipment, so as to effectively ensure that the functions of the equipment are fully played and the equipment can operate safely and stably. In this process, it is also necessary to pay attention to the selection of hydraulic oil, to avoid the selection of mixed hydraulic oil, because it contains a lot of chemical elements, unstable properties, during the use of a certain state, the internal chemical reaction will occur, affecting the hydraulic function of petroleum machinery and equipment.
3, the use of diversified sealing technology
There are many different types of petroleum machinery and equipment, and different hydraulic sealing technologies are also required for different types of machinery and equipment. At present, the rotating blowout preventer is a common petroleum machinery equipment in the petroleum field of our country, in which the expansion capsule programmable control type and the annular rubber core self-sealing type are the rotating blowout preventer used in this equipment. When this equipment is working, the service life of the drill pipe seal structure and the carrying package will directly affect the use of the equipment, so researchers usually focus on this aspect, while ignoring the subcontracting, and the sealing of the entire equipment will not be guaranteed, so in order to solve this problem, it is necessary to take the fluid dynamic pressure sealing ring technology, Improve the sealing and hydraulic performance of the equipment.
4. Clean the petroleum machinery regularly
Regular cleaning of petroleum machinery and equipment can effectively prevent solid impurities from entering the inside of the equipment during operation, affecting the safety of the equipment, and also avoid pipeline blockage in the hydraulic system. In general, the main reason that the hydraulic system is not clean is that the hydraulic system contains impurities, and the oil company does not pay attention to the regular cleaning of the mechanical equipment. Therefore, in the daily management process of petroleum machinery and equipment, it is necessary to develop the corresponding mechanical overhaul and maintenance system, regularly clean the equipment, and formulate the corresponding management system in terms of hydraulic oil type, oil temperature, flow rate, etc., while ensuring that the equipment is thoroughly cleaned regularly. When cleaning the mechanical equipment, it is not only necessary to maintain the outside of the equipment, but also to focus on the internal maintenance to avoid the magazine entering the system and affecting the operation of the equipment.
