Abstract
The utility model discloses a device for displaying pressure and oil level of high-low voltage rare oil station equipment, solves the problem in the prior art that an inspector observes pressure or oil level inconveniently, and has the advantages of simple structure, convenient use, convenience in observing pressure or oil level, and the like. The utility model adopts the structure that the device comprises a display device; the display device is mounted on a control cabinet and connected with a low-voltage pressure and an oil level transducer; and the low-voltage pressure and oil level transducer is mounted on the body of a high-low voltage rare oil station.
Description
Technical field
The utility model relates to a kind of high low pressure Lubricating-oil Station equipment, relates in particular to a kind of pressure and oil level display unit that is applied to high low pressure Lubricating-oil Station equipment.
Background technique
The high low pressure Lubricating-oil Station is mainly used in coal pulverizer bearing lubrication, according to the lubricated work principle design of dynamic and hydrostatic bearing.Be made up of two low pressure pumps and two high pressure pump systems, main frame provides lubricated by low pressure pump when normal operation, and high-pressure service pump is when only being used in host-initiated and stopping.Native system also is applicable to and to guarantee the normal operation of equipment, increases the service life in the sound bearing lubrication system in the equipment such as metallurgy, mine, cement machinery.
The high low pressure Lubricating-oil Station is floated system by low pressure lubricating system and high pressure and is formed, and low pressure lubricating system is made up of vertical gear pump-unit, fuel tank, one-way valve, safety valve, pressure gauge, duplex filter, pressure relay, cooler, solenoid valve, pressure reduction relay etc.High-pressure system mainly contains compositions such as high-pressure plunger pump-unit, high-pressure overflow valve, one-way valve, pressure gauge with electric contact, pipe-line system.Working principle: before main frame is opened, at first open low pressure pump, after low pressure pump is stable, drive high-pressure service pump again.High-pressure system is not established fuel tank separately, and fluid is sent into bearing by sucking-off in the low pressure pump oil outlet.When pressure reaches certain value (being set pressure), main shaft will float under pressure, and can start main frame this moment, after the main frame running steadily, stop high-pressure service pump automatically, and will be lubricated by the low pressure pump fuel feeding.When high-pressure system also is used for main shut-down system, promptly open earlier high-pressure service pump, when pressure reaches certain stationary value, can stop main frame, after safety comes to a complete stop, stop high-pressure service pump, stop low pressure pump again.
Be provided with two gear pumps in the low service system of high low pressure Lubricating-oil Station, under the normal condition, a job, one is standby; Meet accident, when the low service system oil pressure dropped to setting 0.1MPa, stand by pump put into operation, and after the pressure recovery, stand by pump quits work.If stand by pump operation back pressure also descends, when reducing to 0.05MPa, system sends alarm signal.Be provided with safety valve in the system, the set pressure scope is 0～0.5MPa.The oil strain pressure reduction of duplex filter when pressure difference surpasses 0.05MPa, sends signal by the control of pressure reduction relay in the system, and at this moment the handle with filter forwards another cartridge filter working position to, and former cartridge filter is pulled down cleaning.Be provided with thermal switch in the fuel tank, logical cooling water is lower than 35 ℃ and stops automatically when oily temperature is higher than 45 ℃; Can heat automatically, but also manual heating in the time of automatically, heat automatically when oily temperature is lower than 15 ℃, stop heating when reaching 25 ℃.When the oil temperature is higher than 55 ℃, send alarm signal, when oily temperature is lower than 12 ℃, stop low pressure pump and warning.Be provided with the oil level signalling device in the fuel tank, report to the police when oil level is too high, oil level is crossed when hanging down, and stops low pressure pump and reports to the police simultaneously.
The high low pressure Lubricating-oil Station is judged the height of current pressure and oil level by pressure switch and reed switch relay, pressure switch and reed switch relay are installed on the body oil pipe line of oil station, and oil station body generally all is placed in the melt pit, therefore, it is very inconvenient when the personnel of patrolling and examining observe pressure or oil level, and this kind switch can only provide a passive switch amount, promptly when pressure is low or high, export the signal that pressure is low or high, when oil level is low or high, export the signal that oil level is low or high, current pressure and oil level value can not be provided immediately, can not allow the people current force value or the digitizing of oil level value.
Summary of the invention
The purpose of this utility model is exactly a problem very inconvenient when solving that the personnel of patrolling and examining observe pressure or oil level at present, provide a kind of have simple in structure, easy to use, be convenient to the pressure that is applied to high low pressure Lubricating-oil Station equipment and the oil level display unit of observed pressure or oil level.
For achieving the above object, the utility model adopts following technological scheme:
A kind of pressure and oil level display unit that is applied to high low pressure Lubricating-oil Station equipment, comprise a display unit, this display unit is installed on the control cabinet, and display unit is connected with low pressure and oil level transmitter, and low pressure and oil level transmitter are installed on the body of oil station.
Described display unit is a Siemens TD400C display screen, and the TD400C display screen is connected with the CPU226 central processing unit of Siemens S200PLC, and the EM231 analog module of Siemens S200PLC is connected with low pressure and oil level transmitter.Increase low pressure transmitter and oil level transmitter in the utility model, and application Siemens TD400C display screen shows current pressure and oil level value.Transmitter is installed on the basis of oil station, at first the signal of pressure and oil level transmitter is sent into the EM231 module of Siemens S200PLC, calculate by CPU, pressure and oil level value are shown on the TD400C screen, and display screen is installed on the control cabinet of lubrication station, make the inspector only need observe pressure and level value that the data of display screen just can be known current lubricant oil station, also can send warning when pressure or oil level superelevation or when ultralow.
The beneficial effects of the utility model are: simple in structure, easy to use, the inspector only need observe pressure and the level value that the data of display screen just can be known current lubricant oil station, also can send warning when pressure or oil level superelevation or when ultralow.
