1. The management should prevent the discharge pipeline obstruction and the death of the stop valve card.

2. When the rhombus diameter is too much due to wear, the energy consumption of working water increases and the efficiency of the pump is reduced. If necessary, it should be replaced.

3. The lying of the spray of the exit of the nozzle exit is the laryngeal distance (represented by LC) with the lying from the inlet section of the mixed chamber. There is a optimal value, which is usually determined by the test. The distance should not change casually when disassembling. If the LC is too large, the traffic is too large to enter the mixed chamber, so that it cannot be reproduced to the required excretion pressure. The mixed outdoor flow reverses; the LC is too small to make the radio flow insufficient. Or the effective length of the mixing room is shortened, resulting in uneven distribution of export speed. It can be seen that LC is too long or too short, which will increase energy loss.

4. When installing, pay attention to ensuring the concentricity of the nozzle, mixing room and the transparent tube, especially the concentricity of the nozzle and the mixed chamber, otherwise it will cause greater energy loss and even lose the ability to absorb.
