Abstract
The invention belongs to the technical fields of temperature sensor-relay, more particularly to a kind of a kind of process applied in temperature sensor-relay, it is low to solve existing temperature sensor-relay sensitivity, the problem of accurately being monitored to oil temperature cannot be reached.It is packed into active carbon particle in entire thermometer bulb induction tube in the thermometer bulb sub-assembly of temperature sensor, and welds filter screen, filter screen separates capillary and activated carbon, prevents active carbon particle from entering in capillary.The present invention realizes the purpose that raising temperature sensor-relay accurately monitors temperature in diesel engine lube pipe.Have the characteristics that at low cost, operability is strong, can be also applicable in similar-type products that there is larger practical value.The process can be widely used in each field temperature sensor-relay, realize that the purpose accurately monitored to environment temperature, marketing have a extensive future.
Description
Technical field
The invention belongs to the technical fields of temperature sensor-relay, and in particular to a kind of to apply in temperature sensor-
A kind of process in relay is not more than 50 DEG C of temperature sensor-relay particularly for test scope.
Background technology
In diesel engine lube pipe, oil temperature need to be monitored with temperature sensor-relay,
When oil temperature reaches the setting of pressure switch, temperature sensor-alarm relay is less than 3 DEG C~6 DEG C of setting
When, terminate alarm.Traditional temperature sensor-relay is applied on pipeline, and alarm switch disconnects big with the temperature difference of connection
It in 6 DEG C, i.e., persistently alarms when oil temperature reaches setting, 6 DEG C of temperature reduction or more is even lower could to terminate alarm, spirit
Sensitivity is relatively low, cannot achieve the purpose that accurately to monitor oil temperature.
The core element of the temperature sensor-relay is temperature sensor, and temperature sensor is by thermometer bulb sub-assembly and wave
Line pipe sub-assembly two parts are formed by capillary Combination Welding, and the gas of certain pressure is poured into thermometer bulb sub-assembly, are being experienced
When variation of ambient temperature, the gas expansion of inner cavity or contraction, the variation for making combined bellows part experience pressure by capillary are produced
Raw displacement makes preset switches connect alarm.Realize relay in setting switch connection report by controlling aeration pressure in technique
It is alert, but cannot achieve alarm switch to disconnect the requirement for being 3 DEG C~6 DEG C with the temperature difference connected.
Invention content
The present invention is low in order to solve existing temperature sensor-relay sensitivity, cannot reach and accurately be supervised to oil temperature
The problem of control, is supplied to a kind of process applied in temperature sensor-relay, can effectively improve temperature biography
The accurate monitoring to line temperature is realized in the sensitivity of sensor-relay.
The present invention adopts the following technical scheme that realization：
A kind of process applied in temperature sensor-relay, it is characterised in that in the thermometer bulb of temperature sensor
It is packed into active carbon particle in entire thermometer bulb induction tube in sub-assembly, and welds filter screen, filter screen is by capillary and activated carbon
It separates, prevents active carbon particle from entering in capillary.The mesh number of the active carbon particle is 8~16 mesh.
A kind of process applied in temperature sensor-relay is packed into air inlet in the center-pole of thermometer bulb sub-assembly
Capillary, breather capillary, the alignment of three end, center-pole end welds filter screen, will weld the center rod end of filter screen
Insertion has been loaded into the thermometer bulb induction tube of activated carbon, and thermometer bulb induction tube and center-pole are welded together.
Present invention utilizes big, strong to the gas sorption ability features of activated carbon surface product.Under room temperature, certain pressure is poured into
Gas when, more gases are filled in the inner cavity of same volume, it is 3 DEG C~6 DEG C to realize that alarm switch is disconnected with the temperature difference connected
Requirement.
It is tested by taking certain existing type temperature sensor-relay as an example, test temperature is 55 DEG C~100 DEG C, setting report
Alert temperature is 95 DEG C, and thermometer bulb induction tube is put into temperature control water tank, to the improved temperature sensor-relay of the present invention and
Existing temperature sensor-relay is tested, and test result see the table below：
| Set temperature | Alarm temperature | Terminate alarm | The break-make temperature difference | |
| The present invention | 95℃ | 95℃ | 91.7℃ | 3.3℃ |
| Existing temperature sensor-relay | 95℃ | 95℃ | 85℃ | 10℃ |
From test result as it can be seen that it is 3 DEG C~6 that the temperature sensor-relay, which meets the break-make temperature difference, through the invention
DEG C requirement, existing temperature sensor-relay on-off temperature difference be 10 DEG C, be unsatisfactory for the break-make temperature difference be 3 DEG C~6 DEG C
Requirement, poor sensitivity.
The present invention realizes raising temperature sensor-relay（Test scope is not more than 50 DEG C）It is slided in diesel engine
The purpose that temperature is accurately monitored in oil pipe line.Have the characteristics that at low cost, operability is strong, can also be pushed away in similar-type products
Wide application, has larger practical value.The process can be widely used in each field temperature sensor-relay, real
The purpose now accurately monitored to environment temperature, marketing have a extensive future.
