Fig. 2 is the setting position figure of each temperature transducer of the present utility model.
In figure: 1-reactor, 2-homogenizer, 3-oil outlet tube, 4-oil inlet pipe, 5-water-cooling tube, 6-heat exchanger, the total oil inlet pipe of 7-, 11-filler opening, 12-cools down water inlet, 13-oil outlet, 14-Sealing stationary ring.
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Embodiment
As depicted in figs. 1 and 2: the utility model has been announced a kind of homogenizer mechanical seal preventative maintenance system, comprises the first temperature transducer for detection of filler opening 11 temperature, for detection of the second temperature transducer of cooled oil heat exchanger cooling water intake 12 temperature, for detection of the three-temperature sensor of oil outlet 13 temperature, for detection of the 4th temperature transducer, PLC and the display unit of Sealing stationary ring 14 temperature.This display unit with are connected temperature transducer and are connected with this PLC respectively.
This first temperature transducer, the second temperature transducer, three-temperature sensor, the 4th temperature transducer are arranged at respectively filler opening 11, cooled oil heat exchanger cooling water intake 12, oil outlet 13, Sealing stationary ring 14 positions.
Described system also comprises one for detection of the acceleration transducer (not shown) of homogenizer operational vibration amplitude of variation, and described acceleration transducer is arranged on homogenizer 2 shells, and is connected with PLC.Described PLC is with RS485 expansion interface and emergency cutoff interface.Described system has the RT rael time function, can in time with the data measured analysing and processing, make indication.Described system also comprises the alarm unit (not shown), is connected with PLC, in order to give the alarm when temperature exceeds early warning value.
As shown in Figure 2, raw material (as toothpaste) enters homogenizer 2 and further processes after 1 li reaction of reactor.There is cold oil to circulate in homogenizer 2, adopts the sealing of stationary ring formula.Sealing or damage of bearings must cause the interior oil pocket of homogenizer 2 and reactor 1 to communicate, and under the reactor vacuum state, cold oil can enter in reactor, causes product rejection.
The fuel tank that circulates has outside installed heat exchanger 6 additional, and cooling water enters from water-cooling tube 5, and cold oil enters from total oil inlet pipe 7, first will be through over-heat-exchanger 6, and purpose is that inlet oil temperature is stabilized in certain limit.Then pass through oil inlet pipe 4, homogenizer 2 flows out from oil outlet tube 3.At filler opening 11, cooled oil heat exchanger cooling water intake 12, oil outlet 13, Sealing stationary ring 14 positions difference mounting temperature sensors, in order to detect the temperature of above-mentioned four points for measuring temperature.Measured temperature is sent to PLC, by analysis, calculate after output prompting, warning or emergency cutoff.
Have following three kinds of situations to occur: one, filler opening 11 and cools down water inlet 12 temperature difference rise, and after when the heat energy that shows oil might be start large this moment, oil is deposited the large or start of heat, heat production is large; Two, filler opening 11 and oil outlet 13 temperature difference rise, and show that bearing or the Sealing heating value in homogenizer 2 is large; Three, Sealing stationary ring 14 temperature rise, and with oil temperature, larger gap are arranged, and show that stationary ring 14 heating values are large.
As the first situation appears when starting shooting, should compare simultaneously with the available machine time.
As the second situation appears when starting shooting, but extend in time and stablize, bearing or Sealing are normal operation basically.
As the second situation appears when starting shooting, but can not stablize after extending in time but change slowly, bearing or Sealing have the possibility of damage in early stage.
As the second situation appears when starting shooting, and exponential form occurs and rise but extend in time, bearing or Sealing are to damage basically.
As the second and the third situation occurs simultaneously and fast rise when starting shooting, Sealing is to damage basically.
System can arrange each point for measuring temperature temperature pre-warning value and temperature difference early warning value, sets early warning value when currency surpasses, and system will in time sound a warning, and shows on display device.
The homogenizer mechanical seal preventative maintenance system of the present embodiment has following features:
1. native system has the RT rael time function, can and sound a warning to the Current Temperatures RT rael time.
2. can be connected with computer:
Native system has the RS485 interface, can realize telecontrol, can facilitate in time must observe temperature regime.
3. native system has warning function, and over early warning value, system will sound a warning when temperature.
4. native system comprises the emergency cutoff interface, when running into urgency, can in time shut down.
