Description
technical field:
The utility model relates to oil strain technical field, refers in particular to a kind of temperature of power plant steam turbine main oil tank topping up device.
background technology:
The oil system of Steam Turbine in Fire Power Plant is all provided with main oil tank for turbine oil system oil.For ensureing that in oil system, oil is good, need use oil filter filtration, purification.Method is: pick out a road binders pipe in the bottom of main oil tank, and after being connected in series a valve, access oil filter entrance, the outlet of oil filter connects main oil tank top, and middle serial connection valve, oil transportation power is provided by oil strain pump.For ensureing the safe operation of steam turbine, the oil level of main oil tank should keep within the specific limits, therefore needs regular replenishment fresh oil.Fresh oil is poured into from the cover port on main oil tank top by oiling mode often.Do like this deficiency be: on the one hand, refueling operation need manually be carried out, and complex operation, labor intensive; On the other hand, be mixed into fuel tank easily by outside with the impurity in fresh oil, the equipment that affects runs.
utility model content:
The object of the utility model patent is to overcome the deficiency existed in above-mentioned technology, provides a kind of temperature of power plant steam turbine main oil tank topping up device.
The purpose of this utility model realizes as follows: a kind of temperature of power plant steam turbine main oil tank topping up device, comprise controller, main oil tank, oil filter and oil drum, it is characterized in that: main oil tank, electromagnetic valve A, oil strain pump, oil filter, electromagnetic valve B is connected by pipeline successively with main oil tank, form C/LOOP, electromagnetic valve A is connected with bottom main oil tank, electromagnetic valve B is connected with main oil tank top, branch line is provided with between electromagnetic valve A and oil strain pump, pipeline is provided with electromagnetic valve C, line end is inserted in oil drum, main oil tank is provided with fuel level sensor, fuel level sensor, electromagnetic valve A, electromagnetic valve B is connected with controller by wire with electromagnetic valve C.
The beneficial effects of the utility model are: the utility model is reasonable in design, convenient and practical.The design of branch line, avoids being mixed into of impurity in refueling process; The design of electric-control system, not only time saving and energy saving, and achieve the automation of refueling process.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
detailed description of the invention:
With reference to Fig. 1, a kind of temperature of power plant steam turbine main oil tank topping up device.
The purpose of this utility model realizes as follows: a kind of temperature of power plant steam turbine main oil tank topping up device, comprise controller 11, main oil tank 8, oil filter 3 and oil drum 7, it is characterized in that: main oil tank 8, electromagnetic valve A5, oil strain pump 4, oil filter 3, electromagnetic valve B2 is connected by pipeline 1 successively with main oil tank 8, form C/LOOP, electromagnetic valve A5 is connected with bottom main oil tank 8, electromagnetic valve B2 is connected with main oil tank 8 top, branch line 1 is provided with between electromagnetic valve A5 and oil strain pump 4, pipeline 1 is provided with electromagnetic valve C6, pipeline 1 end inserts in oil drum 7, main oil tank 8 is provided with fuel level sensor 9, fuel level sensor 9, electromagnetic valve A5, electromagnetic valve B2 is connected with controller 11 by wire 10 with electromagnetic valve C6.Operation process is as follows: when main oil tank 8 liquid level is in normal range, electromagnetic valve A5 and electromagnetic valve B2 opens, and electromagnetic valve C6 closes, and performs oil strain operation, does not perform refueling operation; When main oil tank 8 oil level is prescribed a time limit lower than lower, signal is passed to controller 11 by fuel level sensor 9, and controller 11 sends signal to each electromagnetic valve, and electromagnetic valve A5 is closed, and electromagnetic valve B2 and electromagnetic valve C6 opens, and performs oil strain operation and refueling operation; When main oil tank 8 oil level reaches in limited time, signal is passed to controller 11 by fuel level sensor 9, and controller 11 sends signal to each electromagnetic valve, and electromagnetic valve A5 and electromagnetic valve B2 is opened, and electromagnetic valve C6 closes, and recovers the operation of normal oil strain, stops refueling operation.
