Abstract

The invention relates to a protective device of a centrifugal oil cleaning system, which comprises an oil inlet valve, an inlet filter, a heater, a centrifugal separator and an oil outlet valve serially connected in a main oil way in sequence, wherein the inlet filter is internally provided with a liquid level sensor; a flow sensor is arranged on an oil way between the inlet filter and the heater; the protective device further comprises a control unit for receiving the signals of the liquid level sensor and the flow sensor; and the control unit is respectively connected with the control circuits of the heater and the centrifugal separator. The protective device of the centrifugal oil cleaning system has the following beneficial effects: compared with the prior art, the protective device has the advantages that the centrifugal oil cleaning system can be prevented from being damaged by too low flow and whether a filter screen in the filter is blocked can be judged so as to give an alarm.

Description

The protective device of centrifugal oil purification system
Technical field
This invention 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 the 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 reduction in the working connection, when the fluid flow reduces, can cause the problems such as overheated heater damage and cyclone idle running in the situation that heater and cyclone power are constant in the working connection, even cause security incident.
Summary of the invention
Goal of the invention: the purpose of this invention 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 the working connection; be provided with liquid level sensor in the described inlet filter; oil circuit between described inlet filter and the 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 control circuit with heater respectively and is connected with cyclone.
Remind operating personnel to change filter screen in the inlet filter for convenient, described protective device also comprises alarm unit, and described alarm unit is connected with control module.
Operation principle: can detect the liquid level of inlet filter inner fluid by the liquid level sensor in the inlet filter, the filter screen when liquid level is too high in the inlet filter in the explanation inlet filter has stopped up or is excessive by the fluid flow of inlet filter; Can detect the flow that enters heater and cyclone fluid by the flow sensor on the oil circuit between inlet filter and the heater, when fluid flow in the working connection that flow sensor detects the filter screen in hour explanation inlet filter stopped up or be less by the flow of inlet filter; When detecting the higher while flow sensor of liquid level, liquid level sensor detects the filter net jam in hour explanation inlet filter of flow in the working connection.When flow sensor detects that the flow value of fluid is lower than the setting value of control module in the working connection; control module cuts off the circuit of heater and cyclone and closes heater and cyclone, reaches the purpose of protection heater and cyclone.When the Height of oil in the inlet filter that liquid level sensor detects when flow sensor detects the flow value of fluid in the working connection and is lower than the setting value of control module is 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 interior filter screen of inlet filter.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: 1, can effectively avoid centrifugal oil purification system since flow cross low cause damage of equipment; 2, can judge whether filter screen in the filter stops up and report to the police.
Description of drawings
Fig. 1 is control principle drawing of the present invention
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
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 the working connection; be provided with liquid level sensor 6 in the described inlet filter 2; oil circuit between described inlet filter 2 and the 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 that heater 3 is connected with cyclone respectively.Described protective device also comprises alarm unit 9, and described alarm unit 9 is connected with control module 8.
Can detect the liquid level of inlet filter 2 inner fluids by the liquid level sensor 6 in the inlet filter, the filter screen when inlet filter 2 interior liquid levels are too high in the explanation inlet filter 2 has stopped up or is excessive by the fluid flow of inlet filter 2; Can detect the flow that enters heater 3 and cyclone 4 fluid by the flow sensor 7 on the oil circuit between inlet filter 2 and the heater 3, when fluid flow in the working connection that flow sensor 7 detects the filter screen in hour explanation inlet filter 2 stopped up or to pass through the flow of inlet filter 2 less; When detecting the higher while flow sensor 7 of liquid level, liquid level sensor 6 detects the filter net jam in hour explanation inlet filter 2 of flow in the working connection.When flow sensor 7 detects that the flow value of fluid is lower than the setting value of control module 8 in the working connection; 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.When the Height of oil in the inlet filter 2 that liquid level sensor 6 detects when flow sensor 7 detects the flow value of fluid in the working connection and is lower than the setting value of control module 8 is 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, and the prompting operating personnel change the filter screen in the inlet filter 2.
