The low speed of fire pump and constant means of check of fast make one’s rounds

The welcome visits Shandong Hairui Zhonglian Pump Industry Co. , ltd. Website, the fire pump that my company is a major produces manufacturer. When you need fire pump type selecting, we will provide the before-sales service such as price of fire pump model, fire pump, in order to offer your referenced alternative. This product information is mix about fire pump low speed constant the knowledge of means of check of fast make one’s rounds:

One, the analysis of means of check of make one’s rounds
Constant means of check of fast make one’s rounds is inside proper time imitate the operating condition of fire control water supply. What its detect is fire pump is started, the whole process that runs normally. And need to improve on pipeline design. More important is the breakdown of electromagnetism a powerful person that should prevent bypass pipe road to go up, must accomplish open when check of make one’s rounds, after check of make one’s rounds is finished shut in time. Means of check of low speed make one’s rounds does not need to be made to the pipeline of fire pump alter, but what its detect is fire pump only a phase in normal operating mode. Fire pump can be divided to be started directly and be started secondhand, the need with greater power is started secondhand. And start secondhand step-down of Y/ △ is started, start from Ou step-down, soft starter is started wait for means. Move in fire pump in, soft starter is started is the level of an early days that fire pump runs only, just be normal ever since move. Frequency conversion method also fails to run labour frequency level. But to preventing fire pump rustily, means of check of low speed make one’s rounds still has certain effect. Relative to character, it has the characteristic that low power comsumption of roll of low frequency drive, low speed, equipment runs.
2, the comparison of means of check of make one’s rounds
In means of check of fire pump make one’s rounds, constant means of check of fast make one’s rounds and means of check of low speed make one’s rounds all are inFire pumpthe function with in safeguarding, rose particular. Look from the point of view that defends management, they can be fastened in fire control water supply apply in all. Relative to character, constant means of check of fast make one’s rounds can mirror the operating conditions with an actual fire pump. Look from the angle of reason of fire pump breakdown, the trouble that fire pump need not cause for a long time basically is the occlusive problem of pump aircrew axis. Electric machinery starts not complete operating mode issue less, reason emphasizes fire pump overly of complete operating mode move, its meaning is not very big. Constant means of check of fast make one’s rounds applies to fire pump to defend the case with bibulous cistern from disappear, reasonable consideration pipeline answers in the design decorate. Put in particular problem in move, can cause very quickly super- pressure, applying in the project is not very appropriate. And constant means of check of fast make one’s rounds and means of check of low speed make one’s rounds have its characteristic each. Although means of check of low speed make one’s rounds is right of fire pump move detect operating mode is not comprehensive, but do not have special requirement to the design of fire pump pipeline, the technology that basically can apply to check of fire pump make one’s rounds asks.
