Abstract
The present invention belongs to the technical field of a temperature sensor-relay and particularly relates to a process method applied to a temperature sensor-relay, and the problems that the sensitivity of an existing temperature sensor-relay is low and the grease temperature can not be precisely monitored. The whole temperature bulb sensing tube in the temperature bulb combination piece of the temperature sensor is loaded with activated carbon particles, a filter net is welded, the filter net separates capillaries from activated carbon, and the activated carbon particles are prevented from entering into the capillaries. According to the process, the purpose of the precise monitoring of the temperature in a diesel engine grease pipeline by the temperature sensor-relay is achieved. The process has the characteristics of low cost and strong practicability, can be promoted and applied in the same type of products, and has a large practical value. The process method can be widely used in the temperature sensor-relays of various fields, the purpose of precisely monitoring an ambient temperature is realized, and the prospect of marketing and application is wide.
Description
Technical field
The invention belongs to the technical field of temperature sensor relay, be specifically related to a kind of a kind of process being applied in temperature sensor relay, be particularly useful for the temperature sensor relay that test scope is not more than 50 DEG C.
Background technology
In diesel engine lube pipe, need to use temperature sensor relay that oil temperature is monitored, when oil temperature reaches the setting of pressure switch, temperature sensor alarm relay, during lower than setting 3 DEG C��6 DEG C, terminates to report to the police. Traditional temperature sensor relay is applied on pipeline, alarm switch disconnects and is all higher than 6 DEG C with the temperature difference connected, namely oil temperature continues to report to the police when reaching setting, temperature reduces by more than 6 DEG C even lower could end and reports to the police, its sensitivity is relatively low, it is impossible to reach the purpose that oil temperature is accurately monitored.
The core parts of this temperature sensor relay are temperature sensor, temperature sensor is formed by capillary tube Combination Welding by thermometer bulb molectron and combined bellows part two parts, thermometer bulb molectron pours into the gas of certain pressure, when experiencing variation of ambient temperature, the gas expansion of inner chamber or contraction, make the change that combined bellows part experiences pressure produce displacement by capillary tube and make preset switches connect warning. Technique realizes relay by control aeration pressure report to the police at setting switch connection, but the instructions for use that the temperature difference is 3 DEG C��6 DEG C that alarm switch disconnects and connects cannot be realized.
Summary of the invention
The present invention is to solve that existing temperature sensor relay sensitivity is low, the problem that can not reach oil temperature is accurately monitored, it is supplied to a kind of process being applied in temperature sensor relay, the sensitivity of temperature sensor relay can be effectively improved, it is achieved the accurate monitoring to line temperature.
The present invention adopts the following technical scheme that realization:
A kind of process being applied in temperature sensor relay, it is characterized in that loading activated carbon granule in the whole thermometer bulb induction tube in the thermometer bulb molectron of temperature sensor, and welding drainage screen, capillary tube and activated carbon are separated by drainage screen, it is prevented that activated carbon granule enters in capillary tube. The order number of described activated carbon granule is 8��16 orders.
A kind of process being applied in temperature sensor relay, the center-pole of thermometer bulb molectron loads air inlet capillary tube, breather capillary, three's end aligns, center-pole end welding drainage screen, the center rod end having welded drainage screen is inserted in the thermometer bulb induction tube having been loaded into activated carbon, thermometer bulb induction tube and center-pole are welded together.
Present invention utilizes activated carbon surface long-pending big, the feature that gas sorption ability is strong. Under room temperature, when pouring into the gas of certain pressure, the inner chamber of same volume is filled with more gas, it is achieved alarm switch disconnects and the instructions for use that the temperature difference is 3 DEG C��6 DEG C connected.
Test for certain type temperature sensor relay existing, test temperature is 55 DEG C��100 DEG C, set alarm temperature as 95 DEG C, thermometer bulb induction tube is put in temperature control water tank, temperature sensor relay and existing temperature sensor relay after the present invention is improved are tested, and test result is shown in following table:
| Design temperature | Alarm temperature | Terminate to report to the police | 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, the instructions for use that the break-make temperature difference is 3 DEG C��6 DEG C is met by temperature sensor relay of the present invention, the existing temperature sensor relay on-off temperature difference is 10 DEG C, is unsatisfactory for the instructions for use that the break-make temperature difference is 3 DEG C��6 DEG C, poor sensitivity.
Present invention achieves and improve the purpose that temperature is accurately monitored by temperature sensor relay (test scope is not more than 50 DEG C) in Diesel engine lube pipe. Have the advantages that cost is low, workable, also can be applicable in similar-type products, there is bigger practical value. This process can be widely used in each field temperature sensor relay, it is achieved ambient temperature carries out the purpose of accurately monitoring, and marketing has a extensive future.
