Abstract
The utility model discloses a protection device for a centrifugal type oil purification system. The protection device comprises an oil inlet valve, an inlet filter, a heater, a centrifugal type separator and an oil outlet valve which are sequentially connected in series to a main oil path, wherein a liquid level sensor is arranged in the inlet filter; a flow sensor is arranged on an oil path between the inlet filter and the heater; the protection device also comprises a control unit for receiving signals of the liquid level sensor and the flow sensor; and the control unit is connected with control circuits of the heater and the centrifugal type separator respectively. Compared with the prior art, the protection device has the beneficial effects that the protection device 1. a phenomenon that equipment is damaged by extremely low flow of the centrifugal type oil purification system can be effectively avoided, and 2. blocking of a filter net in the filter can be judged, and alarming can be realized.
Description
Technical field
This utility model relates to a kind of centrifugal oil purification system for generating set lubricating oil such as firepower, hydroelectric generation unit, industrial steam turbine group, nuclear power stations, particularly a kind of protective device of centrifugal oil purification system.
Background technology
Lubricating oil in unit, mainly plays lubricate, the effects such as heat radiation, cooling, speed governing, oil-cleaning system can keep cleannes in liquid, and operational system is no longer polluted.
At present existing centrifugal oil purification system has the following disadvantages: the inlet filter of cleaning system is easy to blocked, cause fluid flow in working connection to reduce, when the fluid flow reduces, can cause the problems such as overheated heater damage and cyclone idle running in the situation that in working connection, heater and cyclone power are constant, even cause security incident.
Summary of the invention
Goal of the invention: the purpose of this utility model is to provide a kind of can avoiding because inlet filter stops up the protective device that causes centrifugal oil purification system to damage.
Technical scheme: a kind of protective device of centrifugal oil purification system; comprise the inlet valve, inlet filter, heater, cyclone and the delivery valve that are serially connected in successively in working connection; be provided with liquid level sensor in described inlet filter; oil circuit between described inlet filter and heater is provided with flow sensor; described protective device also comprises the control module of receiving liquid level sensor and flow sensor signal, and described control module is connected with the control circuit of heater and cyclone respectively.
For convenient, remind operating personnel to change the filter screen in inlet filter, described protective device also comprises alarm unit, and described alarm unit is connected with control module.
Operation principle: the liquid level of inlet filter inner fluid can be detected by the liquid level sensor in inlet filter, filter screen when liquid level is too high in inlet filter in the explanation inlet filter has stopped up or is excessive by the fluid flow of inlet filter; Can detect by the flow sensor on oil circuit between inlet filter and heater the flow that enters heater and cyclone fluid, in the working connection that flow sensor detects, the fluid flow has stopped up than the filter screen in hour explanation inlet filter or is less by the flow of inlet filter; When detecting the higher while flow sensor of liquid level, liquid level sensor the filter net jam in hour explanation inlet filter of flow in working connection detected.The flow value that fluid in working connection detected when flow sensor is during lower than the setting value of control module; control module cuts off the circuit of heater and cyclone and closes heater and cyclone, reaches the purpose of protection heater and cyclone.Height of oil in flow value that flow sensor detects fluid in the working connection inlet filter that liquid level sensor detects lower than the setting value of control module the time is during higher than the setting value of control module, start alarm unit when control module cuts off heater and cyclone circuit, remind operating personnel to change the filter screen in inlet filter.
Beneficial effect: compared with prior art, its remarkable advantage is the utility model: 1, can effectively avoid centrifugal oil purification system to cause device damage because flow is too low; 2, can judge whether the filter screen in filter stops up and report to the police.
The accompanying drawing explanation
Fig. 1 is the utility model control principle drawing
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure; a kind of protective device of centrifugal oil purification system; comprise the inlet valve 1, inlet filter 2, heater 3, cyclone 4 and the delivery valve 5 that are serially connected in successively in working connection; be provided with liquid level sensor 6 in described inlet filter 2; oil circuit between described inlet filter 2 and heater 3 is provided with flow sensor 7; described protective device also comprises the control module 8 of receiving liquid level sensor 6 and flow sensor 7 signals, and described control module 8 is connected with the control circuit of cyclone 4 with heater 3 respectively.Described protective device also comprises alarm unit 9, and described alarm unit 9 is connected with control module 8.
The liquid level of inlet filter 2 inner fluids can be detected by the liquid level sensor 6 in inlet filter, the filter screen when the interior liquid level of inlet filter 2 is too high in explanation inlet filter 2 has stopped up or is excessive by the fluid flow of inlet filter 2; Can detect by the flow sensor 7 on oil circuit between inlet filter 2 and heater 3 flow that enters heater 3 and cyclone 4 fluid, in the working connection that flow sensor 7 detects, the fluid flow has stopped up than the filter screen in hour explanation inlet filter 2 or is less by the flow of inlet filter 2; When detecting the higher while flow sensor 7 of liquid level, liquid level sensor 6 filter net jam in hour explanation inlet filter 2 of flow in working connection detected.The flow value that fluid in working connection detected when flow sensor 7 is during lower than the setting value of control module 8; the circuit that control module 8 cuts off heater 3 and cyclone 4 is closed heater 3 and cyclone 4, reaches the purpose of protection heater 3 and cyclone 4.Height of oil in flow value that flow sensor 7 detects fluid in the working connection inlet filter 2 that liquid level sensor 6 detects lower than the setting value of control module 8 time is during higher than the setting value of control module 8, control module 8 starts alarm unit 9 when cutting off heater 3 and cyclone 4 circuit, reminds operating personnel to change the filter screen in inlet filter 2.
