Description
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 centrifugal oil purification system with the low discharge protective device.
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.The fluid flow is excessively low to be not only to cause owing to inlet filter is blocked, also might be that other reasons causes that the fluid flow that enters oil-cleaning system itself is just lower, common centrifugal oil purification system can't judge whether inlet filter stops up at present, therefore can't effectively fix a breakdown.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of can avoiding because flow is crossed the centrifugal oil purification system with the low discharge protective device of low cause damage of equipment.
Technical scheme: a kind of centrifugal oil purification system with the low discharge protective device, comprise the inlet valve that is serially connected in successively in the working connection, inlet filter, heater, cyclone and delivery valve, be provided with the first magnetic valve between described electric heater and the cyclone, the oil-out place of described cyclone is provided with check valve, be provided with the second magnetic valve between the oil-in of described the first magnetic valve and the oil-out of check valve, 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; Described protective device also comprises alarm unit, and described alarm unit is connected with control module.
For protection heater more effectively, the oil-out place of described heater is provided with temperature sensor, and described temperature sensor is connected with control module.When the temperature value that detects when temperature sensor was higher than the temperature value that control module sets, control module was closed heater, damages to avoid overheated heater.
In order to prevent that oil pressure is too high in the oil-cleaning system, be provided with pressure switch and control valve between the oil-in of described the first magnetic valve and the oil-out of check valve, in parallel with the second magnetic valve after described pressure switch is connected with control valve.When the oil pressure in the oil-cleaning system reached the pressure switch value, pressure switch was opened, and by control valve system pressure was controlled in the safe pressure value scope, avoided system to damage even produce security incident owing to hypertonia.
Operation principle: when the first magnetic valve was opened the second closed electromagnetic valve, fluid entered cyclone after by heater fluid is carried out centrifugal separation; When the first closed electromagnetic valve the second magnetic valve was opened, fluid directly flowed to delivery valve from the second magnetic valve, because the refluence of fluid has been avoided in the effect of check valve.Can select as required whether need to access cyclone, improve applicability of the present invention.
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: 1, can effectively avoid centrifugal oil purification system because flow is crossed low cause damage of equipment; 2, can judge whether filter screen in the filter stops up and report to the police; 3, can select whether to access cyclone, improve applicability of the present invention; 4, security is higher.
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 centrifugal oil purification system with the low discharge protective device, comprise the inlet valve 1 that is serially connected in successively in the working connection, inlet filter 2, heater 3, cyclone 4 and delivery valve 5, be provided with the first magnetic valve 6 between described electric heater 3 and the cyclone 4, the oil-out place of described cyclone 4 is provided with check valve 7, be provided with the second magnetic valve 8 between the oil-out of the oil-in of described the first magnetic valve 6 and check valve 7, be provided with liquid level sensor 9 in the described inlet filter 2, oil circuit between described inlet filter 2 and the heater 3 is provided with flow sensor 10, described protective device also comprises the control module 11 of receiving liquid level sensor 9 and flow sensor 10 signals, and described control module 11 is connected with the control circuit that heater 3 is connected with cyclone respectively; Described protective device also comprises alarm unit 12, and described alarm unit 12 is connected with control module 11.The oil-out place of described heater 3 is provided with temperature sensor 13, and described temperature sensor 13 is connected with control module 11.Be provided with pressure switch 14 and control valve 15 between the oil-out of the oil-in of described the first magnetic valve 6 and check valve 7, in parallel with the second magnetic valve 8 after described pressure switch 14 is connected with control valve 15.
