lower end of the condenser of the distillation unit, which happens to come across 300mL the bottom of the conical flask, the bottle contains boric acid solution 25--the 50mL and 2~3 drop indicator. Sodium hydroxide solution through the funnel to join 100~150mL, Lysis solution alkalized. Note the funnel neck cannot be empty. ensure a liquid seal.

Open the condenser tubes of condensed water, began distilling. In this process, ensure the amount of steam produced is constant. Collected by 20~30min about

200mL to the liquid in the Erlenmeyer flask, to stop distillation. Lowering of the Erlenmeyer flask, condenser tube left the surface, allow excess condensed water to drip into the bottle, and then rinsing with water condenser tube ends, water drip into the bottle.

Ensure that release ammonia into the Erlenmeyer flask quantitatively, liquid in the bottle is green. 10 or 25mL pipette calibration sulfuric acid titration of liquid in the bottle and, until the color becomes purplish red, read number of ml of the standard solution of sulphuric acid consumption. Determination of the number: measured on the same sample twice. Blank: reagent blank determination, such as sample containers containing nitrogen, then the container should be blank. 6, the results of the calculation method: ammonia nitrogen content in

starches are sample weight to the original weight of the sample expressed as a percentage of weight in the formula: x--sample nitrogen,%;

T--standards for titration of moles of sulfuric acid concentration, mol/l; Vo--blank with sulfuric acid solution volume,

MODES OF OPERATION

There are three modes of operation for the winch:

绞车有三种不同的操作模式

Manual Mode:

手动模式

In manual mode the tension is adjusted via the Manual Increase and

Manual Decrease push buttons. Pressing the Manual Start push-button starts the winch and energises the winch motor. The HDW controls the sequence of events and monitors the system for any fault or abnormality.

The loop tension can then be increased by pressing the Manual Increase push-button or decreased by pressing the Manual Decrease push-button.

The Manual Increase push-button is inhibited at tensions above 100kN to

prevent increasing the tension to an unsafe value. The winch is stopped in manual mode by pressing the Stop push-button.

在手动模式下,通过“手

动增加”和“手动减小”按扭来调整皮带的张力。通过按“手动启

动”按

扭来启动绞车,给绞车电机通电。HDW的PLC来控制所有动作的顺序并监测系统的任何故障和异

常。此时就可以同过“手动增加”按扭或“手动减小”按扭来调节皮带的张力了。当张力大于100KN

时,“手动增加”按扭将失效。通过按人工停止按扭绞车将停机。
