Description
Technical field
The utility model relates to a kind of fire resistant oil vacuum oil-filter support equipment, is specifically related to a kind of automatic detection device of fire resistant oil vacuum oil-filter.
Background technology
In fire resistant oil, containing moisture, impurity and gaseous contamination meeting makes oil product deteriorated rotten.Especially in steam turbine long-time running, inevitably want and contact with moisture, moisture can cause fire resistant oil hydrolysis reaction, hydrolysis reaction can form acid, impurity and greasy filth, also can separate out the adjuvant in oil, water can reduce greasy property and the resistivity of fire resistant oil, and corroding metal accelerates the wearing and tearing of Hydraulic Elements, also cause the bonding of operation valve, equipment is had to very large harm.Mechanical impurity and greasy filth can destroy oil film, the fiber crops of acceleration equipment damage, stop up spool and filtrator, cause operating equipment failure, therefore to remove the moisture in fire resistant oil, acidic materials and mechanical impurity, allow fire resistant oil keep very clean state always, can reduce the failure rate of equipment like this, reduce the replacing of fire resistant oil, when purifying fire resistant oil, also need relevant device will guarantee purifying processing device safe handling, otherwise while there is safety failure in vacuum oil-filter, can not carry out accurately and timely to safety failure reason, equipment positions and gets rid of, even can cause personal damage and equipment to stop production.
Utility model content
The purpose of this utility model is to provide a kind ofly to be had automatic intelligent and controls, certainly props up detection feature, and purification efficiency is high, use simple to operate, failure rate is low, the control device of the fire resistant oil vacuum oil-filter of easy-maintaining.
To achieve these goals, the utility model is by realizing by the following technical solutions:
The control device of fire resistant oil vacuum oil-filter, comprise electric heater, vacuum tank, vacuum pump, PLC controller and oil temperature controller, described vacuum tank is connected with PLC controller circuitry by the pressure transducer being provided with separately respectively with vacuum pump, and PLC controller is connected with vacuum breaker circuit; Described PLC controller is also connected with electric heater, oil temperature controller, over pressure alarm device and photoelectric control froth breaker circuit, and described electric heater connects oil temperature controller, and oil temperature controller connects PLC controller.
As optimal technical scheme of the present utility model, described electric heater is provided with automatic air protection switch and open-phase protection circuit.
As optimal technical scheme of the present utility model, described oil temperature controller is provided with chain controller, and is connected with oil feed pump.
As optimal technical scheme of the present utility model, in described over pressure alarm device, be provided with pressure-protection relay.
As optimal technical scheme of the present utility model, described photoelectric control froth breaker is arranged on vacuum tank inside; Over pressure alarm device is arranged on vacuum tank top and is connected with vacuum pump.
The beneficial effects of the utility model are: with respect to prior art, the utlity model has automatic intelligent and control and self-monitoring feature, purification efficiency is high, use simple to operate, failure rate is low, easy-maintaining, thus make the filtering accuracy of fire resistant oil vacuum oil-filter high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the control device of fire resistant oil vacuum oil-filter, comprise electric heater, vacuum tank, vacuum pump, PLC controller and oil temperature controller, described vacuum tank is connected with PLC controller circuitry by the pressure transducer being provided with separately respectively with vacuum pump, and PLC controller is connected with vacuum breaker circuit; Described PLC controller is also connected with electric heater, oil temperature controller, over pressure alarm device and photoelectric control froth breaker circuit, and described electric heater connects oil temperature controller, and oil temperature controller connects PLC controller.
In the present embodiment, described electric heater is provided with automatic air protection switch and open-phase protection circuit; Described oil temperature controller is provided with chain controller, and is connected with oil feed pump; In described over pressure alarm device, be provided with pressure-protection relay; Photoelectric control froth breaker is arranged on vacuum tank inside; Over pressure alarm device is arranged on vacuum tank top and is connected with vacuum pump.
During work, start vacuum pump switch, vacuum pump pilot lamp is bright, the vacuum values that vacuum degree regulator detects vacuum tank starts drainage pump during to-0.098MPa, fire resistant oil to be clean is under suction function, from oil-in, enter strainer filter, the oarse-grained impurity of elimination, electric heater has automatic air protection switch and open-phase protection circuit, electric heater is provided with chain control program and controlled by oil feed pump, drainage pump could start well heater after starting, can protect the safety of electric heater, fire resistant oil makes temperature rise through well heater, oil temperature controller detects oil temperature and reaches 80 and open drainage pump while spending fire resistant oil is sent into and in vacuum tank, carried out filming processing, make the moisture in fire resistant oil, gas fully evaporates, when over pressure alarm device in vacuum tank detects vacuum tank internal pressure and reaches 0.5Mpa and alarm, to pressure-protection relay, send alerting signal, make machine auto stop.
Photoelectric control froth breaker is set in vacuum tank, when the bubble in oil rises to certain position, vacuum governor auto-admission, reduce vacuum tightness, thereby eliminate the bubble rising, fire resistant oil removes acid treatment by oil pump to amberlite grease filter, then discharges after fine filter filtering fine impurities.
