消防泵是保障消防的重要设施，清楚地了解消防泵的问题，并针对性地掉这些问题，才能保障消防泵的长久有效地使用。和川消小编一起来看看消防泵常见的四大问题。

Fire pump is an important facility to ensure fire safety. Only by clearly understanding the problems of fire pump and solving these problems, can we ensure the long-term and effective use of fire pump. Check the four common problems of fire pumps with Chuanxiao Xiaobian.

问题一

Question 1

消防泵震动严重

Serious vibration of fire pump

1.消防泵与电机轴不同心，调正，对准消防泵与电机轴心。

1. The fire pump is not concentric with the motor shaft, so it is aligned with the fire pump and motor shaft.

2.消防泵轴弯曲，拆下校直或换新的。

2. The fire pump shaft is bent, remove and straighten it or replace it with a new one.

3.叶轮不平衡，拆下找平衡。

3. The impeller is unbalanced, remove it for balancing.

问题二

Question 2

消防泵抽不出液体

The fire pump cannot pump out liquid

1.压出管路太细，管路损失太大，换适合的压出管路。

1. The press out pipeline is too thin and the pipeline loss is too large. Replace it with a suitable press out pipeline.

2.使用扬程超过了设计扬程，重新选消防泵。

2. If the service lift exceeds the design lift, re select the fire pump.

3.吸入管或消防泵内没有排净气体，检修吸入管路并排净气体。

3. The suction pipe or fire pump is not completely vented, and the suction pipe shall be overhauled and the gas shall be vented.

4.吸上高度超过允许范围，按允许吸上高度重新安装消防泵。

4. If the suction height exceeds the allowable range, reinstall the fire pump according to the allowable suction height.

5.输送热的、挥发性的介质，降低吸程或采用倒灌按装。

5. To transport hot and volatile media, reduce the suction head or use reverse filling.

6.转向反了，纠正转向。

6. The steering is reversed. Correct the steering.

7.没有灌注液体，重新灌消防泵。

7. Recharge the fire pump if there is no liquid.

8.吸入管、出水管或消防泵的流道堵塞，杂物。

8. The suction pipe, outlet pipe or the flow passage of the fire pump are blocked to eliminate debris.

问题三

Question 3

机械密封泄漏严重

Serious mechanical seal leakage

1.固定螺钉松动，使弹簧失去作用，紧固螺钉或重新调整弹簧。

1. The fixing screw is loose, making the spring lose its function. Tighten the screw or readjust the spring.

2.弹簧压力不足，重新调整弹簧压缩量或换弹簧。

2. If the spring pressure is insufficient, readjust the spring compression or replace the spring.

3.静环装配歪斜，重装消防泵用静环。

3. The static ring assembly is skewed, and the static ring for fire pump is reinstalled.

4.动换或静环端面腐蚀、磨损或刮伤，修复或更换坏的动环静环。

4. The end face of the moving or stationary ring is corroded, worn or scratched, and the damaged moving or stationary ring is repaired or replaced.

5.轴套加工精度和光洁度不够，影响了动环的轴向移动，换加工精度合格的轴套。

5. The processing accuracy and finish of the shaft sleeve are not enough, which affects the axial movement of the moving ring. Replace the shaft sleeve with a qualified processing accuracy.

6.杂质、异物或介质结晶影响了动环的轴向移动或支撑在动、静环的端面之间，

6. Impurities, foreign matters or medium crystallization affect the axial movement of the moving ring or support between the end faces of the moving and stationary rings,

杂质、异物和结晶，清洗密封元件。

Eliminate impurities, foreign matters and crystals, and clean the sealing elements.

7.动环密封圈装配斜卷或腐蚀变形，重装或更换消防泵用动环密封圈。

7. The moving ring seal ring is assembled obliquely or corroded and deformed. Reinstall or replace the moving ring seal ring for fire pump.

问题四

Question 4

消防泵用电机过热

Motor for fire pump overheated

1.填料压盖压的太紧或机械密封弹簧调的太紧，重新调整压盖或机械密封的弹簧压缩量。

1. If the packing gland is pressed too tightly or the mechanical seal spring is adjusted too tightly, readjust the spring compression of the gland or mechanical seal.

2.使用范围(流量、扬程)超过消防泵的设计要求，按系列型谱选合适的电机。

2. If the scope of use (flow and lift) exceeds the design requirements of the fire pump, select the appropriate motor according to the series type spectrum.

3.消防泵装配质量差，有摩擦处或电机与消防泵轴不同心，检查装配质量，排除装配故障。

3. The assembly quality of the fire pump is poor. If there is friction or the motor is not concentric with the fire pump shaft, check the assembly quality and eliminate the assembly failure.

4.介质比重超过消防泵的配置电机，配置合适的消防泵用电机。

4. If the specific gravity of the medium exceeds that of the fire pump, the motor shall be equipped with a suitable fire pump motor.
