Detailed Description
The invention will be further elucidated below on the basis of a specific embodiment.
A sled piece for offshore platform gas generating set booster lubrication and cooling as shown in figure 1, including structural framework 1, last lubricated oil pump 2, the cooling water pump 3, the lubricated oil pump 4 in advance, the controller 6, lubricating oil heater 7 and the thermostat induction unit of being provided with of structural framework 1, the export of lubricated oil pump 2 in back, cooling water pump 3 and lubricated oil pump 4 in advance all is provided with the check valve. An inlet of the pre-lubricating oil pump 4 is connected with a lubricating oil inlet, an outlet of the pre-lubricating oil pump 4 is connected with an inlet of a lubricating oil heater 7, an outlet of the lubricating oil heater 7 is connected with a unit to be lubricated through an oil pipeline, an inlet of the post-lubricating oil pump 2 is connected with a lubricating oil inlet, and an outlet of the post-lubricating oil pump 2 is connected with a supercharger to be lubricated through an oil pipeline; the thermostat sensing unit includes a first temperature sensor 51 and a second temperature sensor 52, the first temperature sensor 51 is disposed at an inlet of the lube oil heater 7, and the second temperature sensor 52 is disposed at an outlet of the lube oil heater 7; the lubricant oil heater 7 is cylindrical.
The controller 6 is provided with switches for controlling the post-lubricating oil pump 2, the cooling water pump 3, the pre-lubricating oil pump 4 and the lubricating oil heater 7 respectively, and the controller 6 is connected with a power supply. And a time delay relay is arranged in the controller 6 and used for controlling the operation time of the rear lubricating oil pump 2 and the cooling water pump 3.
