Advantages of diesel hand pump is power, good economic performance. Diesel engines and gasoline engines working process has many of the same places, each working cycle has gone through the intake, compression, power, exhaust four stroke. However, since diesel fuel is diesel fuel, the viscosity than gasoline, which is difficult to evaporate, while its auto-ignition temperature but lower than the gas, thereby forming a combustible gas mixture and ignition are different from the gasoline engine. The main difference is that the diesel engine cylinder gas mixture is compression ignition, not lighted. diesel pump manufacturers when the air into the cylinder, compressed air cylinder to the end, the temperature at 500-700 ℃, pressure of 40-50 atm. When the piston approaches top dead center, high-pressure pump on the engine at high pressure to the cylinder injection diesel, diesel oil particles form fine, mixed with air high-pressure high-temperature, gas-diesel hybrid self-burning, violent expansion, generating power, pushing the piston down acting . In this case the temperature 1900-2000 ℃, pressure up to 60-100 atm, great power, therefore, widely used in diesel engines on large diesel vehicles.

Temperature probe calibration applications


temperature probe calibration is the first development, the most widely used class of sensors. Temperature probe calibration market share greatly exceeded the other sensors. From the early 17th century people began using the temperature measurement. In support of semiconductor technologies, this century have developed a semiconductor thermocouple sensor, PN junction storage tank calibration methods and integrated temperature probe calibration.
Two conductors of different materials, such as connecting with each other at some point, the connection point of heating in their unheated parts of the potential difference occurs. The potential difference of the value of the temperature unheated parts of the measuring point is related to the two conductors and related materials. This phenomenon can be used over a wide temperature range appears, if accurate measurement of the potential difference, and then measuring the unheated parts of the ambient temperature, it is possible to accurately know the temperature of the heat spots. Because it must have two conductors of different materials, so called "thermocouple." Thermocouples made of different materials used in different temperature ranges, their sensitivity varies.
Thermocouple sensor has its own advantages and disadvantages, it is relatively low sensitivity, susceptible to environmental interference signal, but also susceptible to temperature drift of the preamplifier, therefore not suitable for measuring small temperature changes. Due to the thickness of the thermocouple temperature probe calibrated sensitivity is independent of the material

Temperature sensor calibration (static,dynamic) steps and methods



Calibration of temperature sensors and calibration, like most other sensors, the sensor is placed in a precise measurement, the known temperature of the environment for some time,calibration management system and then check the sensor output records are consistent with the known ambient temperature, and calculate the error sensor.

Natural environment temperature is always a slowly varying quantities, so under normal circumstances to test the temperature of the sensor is a static, which can meet the actual needs of the vast majority of the temperature sensor. Dynamic test rarely,storage tank calibration methods to achieve dynamic temperature detection device is also minimal.

Because the methods and principles of static temperature sensor test is extremely simple, but rare or standards such information.Improve the temperature sensor is the best way to choose the dynamic characteristics of temperature sensitive materials and reduce the quality of the sensor temperature sensing part, fuel dispenser reducing its thermal inertia.

Temperature sensor calibration procedures



Such as the title, the work involved in the calibration of the temperature sensor,tank calibration software , we used to be corrected several temperature points, and heating and cooling, such as 90 ℃ → 95 ℃ → 100 ℃ → 121 ℃ → 100 ℃ → 95 ℃ → 90 ℃. Now, people who shop with insufficient oil freeze, do not cool program. Will do so with or without risk, there is no calibration of the sensor specification?

First, Our problem is that the temperature of the calibration process cooling process can be omitted.temperature probe calibration

In general, you must conduct a complete and subtraction sequence by sequence alignment sensors are working with mechanical deformation of the displacement process, material strain sensors. This is to detect repeatability and hysteresis characteristics of the sensor.

Temperature sensor is to rely on material changes in the work of the internal molecular state,automated fuel management system , at work are not deformed, the strain of the phenomenon (except the old bimetal structure), so your temperature sensor calibration completely eliminates the need for cooling process, which does not have any impact on your calibration accuracy.

Check out a variety of temperature sensor calibration procedures can be found inside are not required to be Heating and Cooling process.

Advantages of diesel engines is power, good economic performance

Advantages of diesel engines is power, good economic performance. Diesel engine and gasoline engine working process has many of the same places, each working cycle has gone through the intake, compression, power, exhaust four diesel fuel meter stroke. However, due to the diesel fuel is diesel fuel having a viscosity larger than that, does not readily evaporate, but the autoignition temperatures are lower than that of gasoline, thereby forming a combustible gas mixture and the ignition mode are different from the gasoline engine. The main difference is that the diesel engine cylinder pressure in the mixed gas is fired, not lit. The diesel engine when the air entering the cylinder, compressed air in the cylinder to the end, the temperature at 500-700 ℃, pressure 40-50 atm. When the piston approaches top dead center.
