1000l fermentation tanks should be loaded with goods with a low boiling point below 60 ° C, the steam pressure should be fully considered, the liquid steam pressure will increase with the increase of temperature, and the storage and transportation temperature should be considered, there is a critical value, usually to think about 55 ° C, and some areas should think about the temperature difference between 60 ° C; If the temperature is higher than 60 ° C, it is necessary to consider the temperature of storage and transportation, and the temperature difference causes negative pressure in steel drums. Not too high, not too low!
1000l fermentation tanks In order to improve the tank's own sewage capacity, save the cost of manual or mechanical cleaning of the tank's sewage oil, and facilitate the daily maintenance and operation of the tank, Jinrui optimized the sewage structure of the tank. At present, domestic refined oil storage tanks are divided into two kinds: internal floating roof storage tank and arch roof storage tank.

The layout of the application of central dust collector is very important. It can be arranged vertically on the box flower plate or tilted on the flower plate. The vertical layout is more correct from the ash cleaning effect. The lower part of the flower plate is the filter chamber, and the upper part is the air box pulse chamber. An air flow distribution plate is arranged at the inlet of the dust collector.
dust collector is widely used in cement, steel, power, food, metallurgy, chemical and other industrial areas, the overall capacity increased several times, becoming a filter area > 2000m2 large dust collector (GB6719-86 class), It is a solution to solve the problem of the old-fashioned dust collector, which is difficult to collect dust, the filter wind speed is good, the dust cleaning effect is poor, the filter bag is easy to wear and leak, and the operation cost is not low. Compared with the existing bag type and electrostatic precipitator on the market, it has the characteristics of large filter area, low pressure difference, low emission, small volume, good service life, etc., which has become the new direction of the development of industrial dust collector.

The china 4 4 hybrid combiner is a passive component that is widely used in electronic circuits to reduce the amplitude of signals. In practical applications, the performance of china 4 4 hybrid combiner has a very important impact on the stability and signal quality of the circuit.
The main technical specifications of china 4 4 hybrid combiner are as follows:
1. Attenuation quantity
Attenuation is an important index to measure the performance of china 4 4 hybrid combiner. It represents the amplitude attenuation of china 4 4 hybrid combiner to the signal. The amount of attenuation is usually expressed in decibels (dB) and calculated by the formula: A(dB) = 10lg(P2/P1), where P1 and P2 represent the power of the input signal and the output signal, respectively. In practical applications, the size of the attenuation needs to be determined according to the requirements of the circuit. Generally, the attenuation is required to keep stable within a certain frequency range. At the same time, the signal distortion and noise and other factors need to be considered.
2. Frequency range
The frequency range of the china 4 4 hybrid combiner refers to the frequency range in which it can operate effectively. When designing and selecting the china 4 4 hybrid combiner, determine the frequency range of the china 4 4 hybrid combiner according to the operating frequency range of the circuit. If the frequency range of the china 4 4 hybrid combiner is not wide enough, it will cause problems such as distortion and uneven attenuation of the signal during transmission.
3. Insertion loss
Insertion loss refers to the loss of signal amplitude caused by china 4 4 hybrid combiner during operation. The smaller the insertion loss, the less attenuation the china 4 4 hybrid combiner will have on the signal and the better the signal quality. In practical application, the china 4 4 hybrid combiner with low insertion loss should be selected according to the requirements of the circuit.
4. Standing Wave ratio
Standing wave ratio refers to the ratio of reflection coefficient between input and output of china 4 4 hybrid combiner, which reflects the matching degree of china 4 4 hybrid combiner. When the standing wave ratio is 1, the input and output of the china 4 4 hybrid combiner match exactly. In this case, the performance of the china 4 4 hybrid combiner is optimal. If the standing wave ratio is too large, it will cause the reflection and loss of the signal, which will affect the transmission quality of the signal.
5. Temperature coefficient
Temperature coefficient refers to the degree to which the attenuation of china 4 4 hybrid combiner changes with temperature. In practical applications, the performance of the china 4 4 hybrid combiner will also change due to changes in ambient temperature. Therefore, china 4 4 hybrid combiner with low temperature coefficient should be selected to ensure its stability at different temperatures.
6. Bandwidth
Bandwidth refers to the frequency range in which the china 4 4 hybrid combiner can work. In practical applications, china 4 4 hybrid combiner with appropriate bandwidth should be selected according to circuit requirements to ensure its stability and signal quality at different frequencies.
When selecting and designing the china 4 4 hybrid combiner, you need to set these values based on the circuit requirements to ensure the performance and stability of the china 4 4 hybrid combiner.
