Sinopec Northwest Oilfield Branch No. 1 will be energy-saving penetration into every aspect of production, to stimulate awareness of employee energy saving and awareness of innovation, a variety of energy-saving good ideas in practice has achieved good economic returns. Recently came the good news, DYK100-60 * 2 multistage centrifugal pump mechanical seal on the transformation of the station and the heat transfer oil pump drilling grease injection success. It is estimated that the two projects can save 340,000 yuan a year in energy saving. Since the first joint 300,000 light hydrocarbon station has been put into operation, the heat pump bearing lubrication problems have plagued the team members, as the heat transfer oil pump medium temperature up to 280 ℃, the bearing is lubricated with grease, grease at high temperature Easy to wear and tear, (the original equipment without grease hole) After the grease depleted bearings appear dry, and soon will be damaged, bearing damage caused after the shaft and mechanical seal damage. Heat transfer oil pump bearings, shafts and mechanical seals to replace the frequency of 4 months time, and the cost of such imported parts every time up to 3 million yuan. Bearing replacement three times after the bearing bracket can no longer be used, you have to change the total pump head (including for bearings, shafts, mechanical seals and bearing bracket), according to the calculation of the two pumps a day only the maintenance cost of up to 28 million yuan. Faced with the production problems, a number of technical staff repeatedly study and analysis: Bearing is too high temperature grease consumption is too large, under normal working conditions can not be filled with grease, pump must disassemble after cleaning and filling, At the same time under working conditions can not be timely assessment of the amount of grease, which is the root causes of bearing and attachment vulnerability. In February 2007, the first joint technician decided to experimentally drill a 3mm diameter, 20mm, grease filling hole on a pump bearing bracket so grease the grease under the conditions of a heat conducting oil pump The gun can be raised. After a month of running the observation, the effect is very good, in March 2007 on another pump the same technical transformation. As of March 2008, two heat transfer oil pump is operating normally without replacement of any spare parts. Facts have proved once again that this small technical reform has been a success. The successful application of the heat-conducting oil pump to increase the grease injection hole technology not only reduces the workload of pump maintenance, but also saves the maintenance cost of more than 280,000 yuan every year. More importantly, it guarantees the normal production of the light hydrocarbon recovery unit, Won the precious time. Due to the particularity of the nature of production, Yulian 800,000 tons unloading station is mostly heavy oil with large sediment transport capacity. In the process of using, the external pump often has high temperature, and the mechanical seal of the pump is also over-heated And frequently damaged. On duty staff had better new seal to solve the immediate needs of the day, the face of the situation is okay today, after a few days sealed and damaged, missed the old problems again, the team through a number of adjustments or can not be Minato Effective, workers are very annoyed, and sometimes the "hot damage" has become incurable. In the critical period of production, the safe and stable operation of equipment is directly related to the overall process of production. To this end, the pump repair monitor Chen Zongyou locked his brow, he organized the team to the scene on the pump body anatomy, repeated research, and team members to discuss countermeasures, in the fierce debate and discuss the machine seal heat generated and damaged at They are slowly clear up. Chen Zongyou that machine seals at high speed, medium high sediment concentration, heavy oil circulation is slow, the lack of timely enough cooling cooling process, resulting in mechanical seal long-term high temperature operation rupture damage. Seize the key to the problem, the next job is to find a suitable temperature seal machine working environment, this is the fundamental treatment of this chronic illness. Pump repair members through trial and error, the use of pump cycle pressure, the outlet high-pressure side of the transfer of clean media, after the transformation of the machine base into the hole washing machine sealing ring, the net ring and the surface area of ​​sand, and then into the pump chamber, This continuous cycle, reducing the high temperature machine seal operation, to achieve cooling effect. Mechanical seal operating temperature dropped from 95 ℃ to 56 ℃, the temperature reached the ideal state. After the transformation of the mechanical seal by observing the "high temperature damage syndrome" was completely eradicated. Its service life has also been greatly extended. Careful pump repair staff to do a simple calculation, this reform can save pump repair costs 63,000 yuan.
