As further optimal way, be provided with the liquid level liquid thermometer, fluid level controller, temperature transducer, filter, air-strainer and the heater that link to each other with control system in the said fuel tank.
Preferred as further, said filter is the magnetic web filter.
Preferred as further, said temperature transducer is a platinum thermoresistance.
The working principle of the utility model with the effect as follows:
When bearing normally moved, fuel tank and bearing support and pump-unit broke off, and pump-unit is communicated with formation bath lubrication mode with bearing support, and it is lubricated reliably to guarantee that bearing obtains; When fuel tank is communicated with pump-unit and bearing support, but lubricant oil natural back flow or be pumped to fuel tank forms the forced feed lubricating system, and it is good lubricated to guarantee that bearing obtains under low temperature environment; Long-time shut down or during maintenance, pump-unit quits work, fuel tank with and bearing support be communicated with, but lubricant oil natural back flow or be pumped to fuel tank, lubricant oil can be owing to sharp freezing attached to causing the not phenomenon of easy-clear on bearing and the bearing support.
Compared with prior art; The beneficial effect of the utility model: the utility model bearing-lubricating device has the advantage of bath lubrication and the lubricated dual mode of forced feed concurrently; Compare with bath lubrication; The assurance that more is easy to get of the quality of lubricant oil, practical region and repair time are wider, and more oil change is more convenient; Compare with forced feed is lubricated, oil feed line is simpler, controls easylier, and water environment capacity is stronger, and single-pump system and easy supervisory system make its cost lower; Therefore, the utility model bearing-lubricating device can effectively reduce cost of equipment, especially can satisfy the requirement that it uses at low temperatures.
