Abstract

The utility model discloses a thin oil station comprising a monitoring module, a controller and a touch screen, wherein the controller is disposed on the thin oil station and is connected with the monitoring module and the touch screen. The thin oil station collects real-time control information of a temperature sensor, a pressure transmitter, differential pressure transmitter, a liquid level transmitter and a flow transmitter in the monitoring module through the controller, sends the collected signals to the far-end touch screen, such as the touch screen disposed in a professional office, and realizes the display of the relevant data information of the thin oil station in the touch screen. The controller and the touch screen can also send operating parameter information and input and output instructions mutually for the real-time remote control of the thin oil station, so spot check personnel do not need to undertake on-site monitoring in a comparatively poor working environment.

Description

Lubricating-oil Station
Technical field
The present invention relates to the remote control technology of Lubricating-oil Station in the heavy mechanical equipment, more particularly, relate to a kind of Lubricating-oil Station.
Background technique
Lubricating-oil Station is mainly used in the centralized lubrication system of the servomechanism and the bearing of heavy mechanical equipment, according to the dynamic and static pressure lubricating principle, when low speed stops or start, use high-pressure system, use low service system during proper functioning, the normal operation of assurance equipment, the working life of improving hydrostatic bearing.Lubricating-oil Station mainly is made up of high pressure and low pressure gear pump oil supply system, be provided with filtration, voltage stabilizing, heating, cooling unit and correlate meter and control system, the oil temperature supplying of temperature sensor monitors fuel tank wherein, the running state and the system pressure index of pressure transmitter monitoring pump, differential pressure transmitter monitoring oil filtering system switch filtering device, the liquid level of fluid level transmitter monitoring fuel tank, the state of flow transmitter monitoring oil return feeding system etc.Before heavy mechanical equipment starts operation, start the low pressure gear pump of Lubricating-oil Station earlier, after low-pressure oil supply system stable operation, restart high-pressure gear pump, operation high-pressure fuel supply system fuel feeding is to the dynamic and hydrostatic bearing system, make and form enough oil films between static axle and the bearing, the heavy mechanical equipment main shaft machinery of after floating under the effect of pressure oil, reruning, high-pressure gear pump out of service after machinery operates steadily, and only move low pressure gear pump, provide low pressure oil supply lubricated continually and steadily to each lubricating point of machinery.The high-pressure gear pump that reruns when machinery is shut down can stop the high and low pressure gear pump after machinery comes to a complete stop, stop the operation of high low pressure Lubricating-oil Station.But there is following problem in present Lubricating-oil Station:
1) temperature transducer, pressure transmitter, differential pressure transmitter, fluid level transmitter and the flow transmitter etc. in the interior monitoring module of Lubricating-oil Station need spot check personnel on-site supervision, the many and complicated easy break-down of conjunction cable of control wirings such as corresponding warning and electrical interlocks; The operation of Lubricating-oil Station does not simultaneously have perfect operation logic, chain control automatically, be prone to operation troubles, and the Lubricating-oil Station scene exists noise pollution and contamination by dust etc., working environment is relatively poor relatively, except that Distributed Control System DCS, other for example specially the place that needs remote monitoring such as worker office because of not easily watch-dog can not implement to monitor.
2) carry out dividing potential drop by high pressure oil pump and form high-pressure oil feed loop and low pressure oil supply loop, when selecting the power of pump, will satisfy the required pump of high low pressure fuel feeding like this, power of motor is just big, and very short time is just used in high-pressure oil feed when machinery starts and stops, be that low pressure oil supply is lubricated At All Other Times, adopt above-mentioned structure to be unfavorable for the saving of the energy.
3) outlet pressure of Lubricating-oil Station device can fluctuate with the consumption of flow oily in the pipeline and lubricating point in flickering, and fuel feeding has the phenomenon of pressure surge or flow pulsation when lubricated, and it is lubricated unreliable to cause, the fuel feeding instability.
4) because Lubricating-oil Station adopts is three phase mains, therefore operation always needs artificial field adjustable to confirm the traffic direction of pump after first operation or overhaul of the equipments, can bring unsafe factor to operator like this.
Summary of the invention
At exist in the prior art except that centralized control system, Lubricating-oil Station can not implement the problem of remote monitoring because of there being watch-dog easily, the purpose of this invention is to provide a kind of Lubricating-oil Station that can realize remote monitoring easily.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of Lubricating-oil Station comprises monitoring module, also comprises controller and touch screen, and described controller is located on the Lubricating-oil Station, and controller is connected with monitoring module and touch screen respectively.
Described monitoring module, controller and touch screen are equipped with the RS485 interface.
Adopt modbus communication protocol between described monitoring module, controller and the touch screen.
Described touch screen comprises the input output control and the interlock protection control of long-range with local conversion and control, monitoring module.
Described monitoring module comprises temperature transducer, pressure transmitter, differential pressure transmitter, fluid level transmitter and flow transmitter.
Described Lubricating-oil Station comprises high pressure oil pump and low pressure fuel pump, and described high pressure oil pump and low pressure fuel pump are connected with external power supply respectively.
Described high pressure oil delivery side of pump and low pressure oil delivery side of pump are equipped with voltage stabilizer.
Described Lubricating-oil Station also comprises phase controller, and described high pressure oil pump and low pressure fuel pump all are connected with phase controller; Described phase controller also is connected with controller.
Compared with prior art, adopt a kind of Lubricating-oil Station of the present invention, by controller to the temperature transducer in the monitoring module, pressure transmitter, differential pressure transmitter, after the control information of fluid level transmitter and flow transmitter etc. is gathered in real time, to send what be located at far-end to for example can be the touch screen of special worker office with gathering signal, on touch screen, realize the related data information of Lubricating-oil Station is shown, controller and touch screen also transmit the instruction of trip information and input output mutually, Lubricating-oil Station is carried out real-time telecontrol, thereby do not need the spot check personnel in relatively poor relatively working environment, to carry out on-site supervision.
