Equipment composition and working principle of steam engine oil system
Through the debugging of 4 sets of units, it was found that the equipment composition, working principle and working methods of this steam engine oil system all have their own uniqueness. It is worth learning and drawing from domestic manufacturers. System Introduction The turbine oil system is mainly composed of main oil pump, AC oil pump, DC oil pump, oil cooler, oil filter, exhaust fan and main tank. The oil passages are divided into power oil, control oil and lubricating oil. The oil quality of each oil passage adopts No. 32 turbine oil in the main fuel tank. The oil return of each oil passage adopts the mother control, and the oil return from each road to the main oil tank of the steam turbine. . The main oil pump driven by the turbine shaft is located in front of the nose. When the unit is operating normally, the main oil pump outlet oil line supplies oil to the lubrication and regulation system, respectively. Two oil coolers, one for operation and one for standby, can be switched online via a three-way valve. The function of the oil cooler is to maintain the normal oil temperature during unit operation. The oil filter can achieve half-side operation, on-line switching, and online cleaning through the switching valve. The function of the oil filter is to ensure the cleanness of oil in the system. The system is equipped with a hydraulic adjustment device that can adjust the power oil pressure, lubricating oil pressure and control oil pressure. The system also has a low oil pressure test device that interlocks and starts the AC and DC oil pumps when the oil pressure in the oil system is low. The design features of the northeast electric power technology system are small in number and relatively simple in composition. The number of components of the 12MW steam turbine oil system produced in Austria is small. This will inevitably reduce the investment costs and operating costs of the units, and at the same time reduce the maintenance of the equipment by the production operations personnel. . In addition to the main oil pump, AC Lubricating oil pump, DC accident oil pump, rolling stock device, oil cooler, oil filter, exhaust fan, and main fuel tank, the domestic 12MW steam turbine oil system also includes a high-pressure starter oil pump and two shots. Oiler. Due to the increase in the number of system devices, there are inevitably the following disadvantages: The large number of devices constitutes a large amount of equipment maintenance, and the capital investment cost increases. As the high pressure starting oil pump and two injectors are generally installed inside the fuel tank, and the system Operation requires a certain level of oil, which requires an increase in the volume of the fuel tank to meet the requirements of the system operation, which will inevitably lead to increased operating costs. Three Screw Pump be used transfer many kind of oil, like: diesel fuel oil, lube oil, engine oil etc, temperature can not over 150 degree. three screw oil pump's flow rate and pressure all higher than Gear Pump 's, so when gear pump can not meet customer's requirment we will choose three screw oil pump for customer. this kind of pump smooth operation, low noise, widely used in various industries. heat insulation jacket three Screw Pump can be used to transfer high temperature high viscosity oil and bitimen. pump max can bear 300 degree.
