川消小編認(rèn)為對(duì)消防泵進(jìn)行維修保養(yǎng)，主要的目的是耳確保水泵始終處于良好的運(yùn)行或備用狀態(tài)。下面來詳細(xì)講講相關(guān)事項(xiàng)吧。
Chuanxiao Xiaobian believes that the main purpose of the maintenance of the fire pump is to ensure that the pump is always in good operation or standby state. Let's talk about related matters in detail.
1.安裝消防泵時(shí)，電纜線要架空，電源線不要太長(zhǎng)。機(jī)組下水時(shí)切勿使電纜受力，以免引起電源線斷裂。消防泵不要沉入泥中，否則會(huì)導(dǎo)致電機(jī)散熱不良而燒壞電機(jī)繞組。
1. When installing the fire pump, the cable shall be overhead and the power line shall not be too long. When the unit is launched, do not stress the cable to avoid breaking the power line. Do not sink the fire pump into the mud, otherwise it will cause poor heat dissipation of the motor and burn the motor winding.
2.選購(gòu)消防泵時(shí)應(yīng)留意其型號(hào)、流量和揚(yáng)程。如選用的規(guī)格不恰當(dāng)，將無法獲得足夠的出水量，不能發(fā)揮機(jī)組的效率。另外，還應(yīng)搞清電機(jī)的旋轉(zhuǎn)方向，某些類型的消防泵正轉(zhuǎn)和反轉(zhuǎn)時(shí)皆可出水，但反轉(zhuǎn)時(shí)出水量小、電流大，其反轉(zhuǎn)會(huì)損壞電機(jī)繞組。為防止消防泵在水下工作時(shí)漏電而引發(fā)觸電事故，應(yīng)裝有漏電保護(hù)開關(guān)。
2. Pay attention to its model, flow and lift when purchasing fire pump. If the selected specifications are not appropriate, it will not be possible to obtain sufficient water output and the efficiency of the unit will not be brought into play. In addition, the rotation direction of the motor should also be clear. Some types of fire pumps can discharge water during normal rotation and reverse rotation, but the water output is small and the current is large during reverse rotation, and the reverse transfer will damage the motor winding. In order to prevent electric shock caused by leakage of fire pump when working underwater, leakage protection switch shall be installed.
3.平時(shí)多檢查電機(jī)。如發(fā)現(xiàn)下蓋有裂紋、橡膠密封環(huán)損壞或失效等，應(yīng)及時(shí)更換或修復(fù)，以防水滲入機(jī)器。
3. Check the motor frequently. In case of cracks on the lower cover, damage or failure of the rubber sealing ring, etc., it shall be replaced or repaired in time to prevent water from penetrating into the machine.
4.盡量避免在低壓時(shí)開機(jī)。電源電壓與額定電壓不可相差10%，電壓過高引起電機(jī)過熱而燒壞繞組，電壓過低則電機(jī)轉(zhuǎn)速下降，如達(dá)不到額定轉(zhuǎn)速的70%時(shí)，啟動(dòng)離心開關(guān)會(huì)閉合，造成啟動(dòng)繞組長(zhǎng)時(shí)間通電而發(fā)熱甚燒壞繞組和電容器。不要頻繁地開關(guān)電機(jī)，這是因?yàn)殡姳猛＾D(zhuǎn)時(shí)會(huì)產(chǎn)生回流，若立即開機(jī)，會(huì)使電機(jī)負(fù)載啟動(dòng)，導(dǎo)致啟動(dòng)電流過大而燒壞繞組。
4. Try to avoid starting at low voltage. The power supply voltage shall not differ from the rated voltage by 10%. If the voltage is too high, the motor will overheat and burn out the winding. If the voltage is too low, the motor speed will drop. If the voltage is less than 70% of the rated speed, the startup centrifugal switch will close, causing the startup winding to be energized for a long time and heat up or even burn out the winding and capacitor. Do not switch on and off the motor frequently because the electric pump will generate backflow when it stops running. If it is started immediately, the motor load will start, resulting in excessive starting current and burning the winding.
5.切莫讓消防泵長(zhǎng)期超負(fù)荷運(yùn)轉(zhuǎn)，不要抽含沙量大的水，電泵脫水運(yùn)行的時(shí)間不宜過長(zhǎng)，以免使電機(jī)過熱而燒毀。機(jī)組在作業(yè)中，操作者必須隨時(shí)觀察其工作電壓和電流是否在銘牌上規(guī)定的數(shù)值內(nèi)，若不符合應(yīng)使電機(jī)停止運(yùn)轉(zhuǎn)，找出原因并排除故障。
5. Do not allow the fire pump to operate overloaded for a long time. Do not pump water with large sand content. The dehydration operation time of the electric pump should not be too long to avoid overheating and burning of the motor. During the operation of the unit, the operator must observe whether the working voltage and current are within the values specified on the nameplate at any time. If not, the motor shall be stopped to find out the cause and eliminate the fault.
此外消防用泵不能以一般使用場(chǎng)合配套的泵的功率來配套消防泵組，消防泵畢競(jìng)有其特殊的要求，特別是功率的余量上，在很多情況下用戶是難以接受的，強(qiáng)調(diào)這一點(diǎn)是保證消防泵的運(yùn)行所必須的。有疑問可以來我們網(wǎng)站

In addition, the fire pump cannot be matched with the fire pump set with the power of the pump matched in the general use. The fire pump Bijing has its special safety requirements, especially the power margin, which is difficult for users to accept in many cases. It is necessary to emphasize this point to ensure the safe operation of the fire pump. If you have any questions, you can come to our website http://www.xintli.net Consultation and understanding.
