Reduce the pump station oil consumption

Reduce the pumping stations, 2018 - consumption of lubricating oil 12 - Abstract: 29 injection pump unit is a major production of oilfield water injection station equipment, and the high quality lubrication is the key to whether normal operation. Aiming at water injection station often oil and leakage of oil, the water lubrication system failures, such as search by taking countermeasures, reduce the pumping station, consumption of lubricating oil to avoid causing serious economic losses, to ensure the normal operation of the water injection station. Keywords: equipment; Lubrication; Reduce consumption status quo survey 1 victory oil field production plant two ore - five, winning seven water injection station eight existing injection pump units, equipped with 8 sets of high voltage motor, the motor alone, 3 sets of injection pump pressure lubrication cycle system, auxiliary pump eight units, underground tank of four groups, four elevated tank. In recent years, due to various reasons, resulting in frequent oil and leakage of oil, the water within the station such as lubrication system fault, the lubricating oil changed frequently, and even burning bush phenomenon, not only affects the normal operation of the water injection station, more serious economic losses. 2 analysis of the causes by looking at the raw data of the water injection station, analyzes 2009 lubrication system failure situation, See table 1) , find out the major problems affecting lubrication system failure is loss of lubricating oil, lubricating oil consumption in 2009 4. 85 t, total cost of 6. 790000 yuan. Analysis and positive research, after some discussion we determine three factors for the major problems affecting lubrication system failure. 2. 1 drain system design is not reasonable access to water injection station oil consumption records, found that because of drain system problem caused by oil changes (44%), there are 4 times of sewage leaked packing scale, lead to sewage into the bearing lubricating oil chamber, the lubricating oil metamorphic replacement. 2. 2 inspection maintenance does not reach the designated position by looking at water injection station inspection records, lubricating oil consumption records, in 2010 as a result of inspection, maintenance, inadequate lubricating oil to replace three times, 33. 3%, which leads to the change lubricating oil into the water. 2. 3 oil valve too flexible low iron PN16/20 for ordinary oil valve, switch degree is small, it is difficult to control oil, easy to run or tile burning oil. 3 develop countermeasures in view of the will find out, we have the following countermeasures table ( See table 2) 。 To implement 4 4 countermeasures. 1 modified packing drain system, increase the overflow hole injection pump of sewage leaked packing, are on the outside of the stuffing box, packing gland at the bottom, drain the internal cake fouling, fall off after blocking drainage hole and pipe, when the sewage water after reaching the part of the pump shaft into the bearing chamber, namely along the pump shaft into the bearing lubricating oil chamber, causing oil emulsification, emulsifying oil from the oil return line flow back into the lubricating oil tank, make whole oil emulsion lubricating oil system, not only cause the tile burning failure, and all need to change the lubricating oil. In view of the drainage hole blockage caused by damage, we decided to modify and weaved drain system. Reform measures: at 3 cm to below the pump shaft, pump bearing support on open a 10 mm diameter of the overflow hole, after the drain plug, water level even reach this position also can flow out, make inspection personnel in time, avoid sewage along the pump shaft into the lubricating oil chamber, oil emulsification and tile burning accident. 4. 2 replace high pressure valves and supporting pipe water injection station is lubrication part of the main pump bearing, bearing bush before and after each unit is controlled by a single oil gate, currently used in oil valve PN16/20 for low pressure cast iron valve, the valve switch too sensitive is not easy to control, the vibration can make the gate change switch, easy to run large amount of oil of oil, oil amount is too small to bearing shell temperature on the high side. And in the process of staff for equipment cleaning maintenance, often inadvertently touched the handwheel and close the oil gate, a tile burning oil supply disruptions. For the operators can control accurately, we change to the gate, with high pressure needle valve DN15 type replaces the original use common low pressure valve, so that under the condition of the same oil increases the open degree, and the valve switch is tighter than before a lot, not only convenient adjustment, can easily control the oil flow, but also avoid the tile burning phenomenon. In the process of implementation, due to the pipe size and valves do not form a complete set, need to piping and fittings, we contact the maintenance, the motor oil oiling points, change the original line size, the six points of oil pipeline replacement for four points of oil pipeline. 4. 3 with scientific management methods to strengthen equipment monitoring quality lubrication can not only prolong the service life of equipment, can also improve the quality of economic operation, at the same time can timely prevent the happening of the equipment operation reliability and lubrication failure, in order to realize guarantees safe operation and reduce oil replacement equipment. 1) Using the 'four inspection method, strengthen the supervision and inspection efforts, focus on the change of the equipment of various operation parameters, discover the lubrication system failure, timely cleaning sewage scaling inside the pump head, ensure the quality of the lubricating oil and lubrication effect. 2) Using the 'three ones' measures for the management of lubricating oil, combined the qualitative and quantitative detection, and strengthening the management of lubrication monitoring and unqualified oil filter, change in time, avoid the happening of the lubricating oil replacement and equipment failure. 5 effect check our lubrication system fault statistics for 2010, compared with the same period in 2009 effect is as follows: 1) Lubrication system fault frequency by measures before 16 times dropped to 3 times; 2) Lubricating oil replacement number by 4 measures before. 08 t dropped to 1. 18 t, saving lubricating oil 2. 9 t, benefits & 14000 times; 2. 9 - 3500 ( Costs) = 35700 yuan. As you can see, after the above measures reduced the number of lubrication system fault and lubricating oil use, its late benefit more substantial, to achieve the goal of authors efficiency.
