Auto Wedge Base Lamp
Wedge is the specific way to seal the bulb base. It is applied on many different types of bulb, such as T5, T6.5, T10, T13, T15 and T20. T5 bulb is usually be used as dashboard. T10 bulb are usually be used as interior lights, side indicators, front parking lights, 3rd stop light, glove compartment lights and license plate lights. T15 are usually be used as 3rd stop light, stop lights, rear fog light and reversing light. T20 are usually be used as front indicators, front parking lights, 3rd stop light, rear indicators, reversing light and stop lights.

The distiller is an all-glass structure. Distillers can be removed. Steam cleaning is set after each sample is distilled. During the empty steam cleaning process, the cooling water in the condenser tube can be automatically discharged, the temperature in the tube can be increased, and high-temperature steam can be fully used to drive away trace residual ammonia, thereby effectively overcoming 15N cross-contamination. The center of the distillation system is the rotating body, which is already the core part of the automatic Kjeldahl nitrogen analyzer. Both ends are a pair of mechanical logic components, and they have a vent valve, a base valve, a steam valve, and a cooling water valve. This logic element is designed according to the analysis program and performs the respective logic functions in order.
The Huale-distillation unit rotates for one week, including seven steps of adding alkali, alkali cleaning, cooling water, distilling, ammonia absorption, unloading cooling water and steam cleaning. Each step is arranged at a specific location. Therefore, the six-unit distiller only requires a steam system, a set of alkali, alkali cleaning and steam cleaning devices, simplifying the structure. The electronic control system is the control center of the automatic Kjeldahl nitrogen analyzer. It controls the mechanical logic unit through the integrated block logic circuit to complete the sample distillation process.
The dynamics study in the automatic Kjeldahl nitrogen analyzer has a great effect on the design of the instrument and the improvement of the precision on the structure. A sudden change in the ammonia distillation shows that the amount of steam is substantially more than 90% in the first 60-120 seconds, and the others are delayed to within 500-700 seconds. At the early and late stages of the measurement process, the reduction of steam condensate will occur. The test results show that the automatic Kjeldahl nitrogen analyzer is unstable under the condition of high ammonia concentration, and the absorption change range is relatively large, so the control The early absorption of ammonia concentration is the key.
Distillation design and test process of automatic Kjeldahl apparatus
The automatic Kjeldahl nitrogen analyzer has been presented to everyone after continuous improvement and development. It has more advantages. In the step of distillation of the instrument, the analysis of the same batch of samples can be performed continuously according to the corresponding order. The above manner is favorable to steam supply, and its improved stability leads to a reduction in the magnitude of the change. The distillation time of the original sample is continuously performed in one week. The time required for each sample is 10 to 15 minutes. It can fully satisfy the distillation time conditions. Each batch of samples is performed in different units, and one hour can be completed on average. 25-30 samples greatly improve efficiency.
