2、消防泵的串聯(lián)是將一臺(tái)泵的出水口與另一臺(tái)泵的吸水管直接相連，兩臺(tái)泵同時(shí)運(yùn)行。消防泵串聯(lián)可在流量恒定時(shí)增加揚(yáng)程。消防泵并聯(lián)是通過兩臺(tái)或多臺(tái)消防泵同時(shí)向消防供水系統(tǒng)供水。消防泵并聯(lián)主要是為了增加流量。
2. The series connection of fire pumps is to directly connect the water outlet of one pump with the suction pipe of the other pump, and the two pumps operate at the same time. The fire pump in series can increase the lift when the flow is constant. Parallel connection of fire pumps means that two or more fire pumps supply water to the fire water supply system at the same time. Parallel connection of fire pumps is mainly to increase the flow.
3、川消消防泵直接從市政管網(wǎng)抽水時(shí)，應(yīng)在消防泵的出水管上安裝帶空氣隔板的防回流裝置。當(dāng)吸水口無吸水井時(shí)，應(yīng)在吸水口安裝防旋流器。
3. When Chuanxiao fire pump directly draws water from the municipal pipe network, an anti backflow device with air baffle shall be installed on the outlet pipe of the fire pump. When there is no suction well at the suction port, an anti cyclone shall be installed at the suction port.
4、消防水池內(nèi)消防泵吸水管喇叭口的有效水位不小于600mm。使用旋風(fēng)防噴器時(shí)，淹沒深度不應(yīng)小于200mm。消防泵吸水管上應(yīng)設(shè)置明桿閘閥或帶自鎖裝置的蝶閥，但設(shè)置暗桿閥時(shí)，應(yīng)設(shè)置開度刻度和標(biāo)志；當(dāng)管徑超過DN300時(shí)，應(yīng)設(shè)置電動(dòng)閥。消防泵吸水管通過消防水池時(shí)，應(yīng)采用柔性套管；采用剛性防水套管時(shí)，應(yīng)在泵的吸入管上設(shè)置柔性接頭，管徑不大于DN150。
4. The effective water level at the bell mouth of the fire pump suction pipe in the fire pool shall not be less than 600mm. When using cyclone BOP, the submergence depth shall not be less than 200mm. Rising stem gate valve or butterfly valve with self-locking device shall be set on the suction pipe of the fire pump, but when setting the Non rising stem valve, the opening scale and mark shall be set; When the pipe diameter exceeds DN300, an electric valve shall be set. When the suction pipe of the fire pump passes through the fire pool, the flexible sleeve shall be used; When rigid waterproof casing is used, flexible joint shall be set on the suction pipe of the pump, and the pipe diameter shall not be greater than DN150.
5、消防泵出水管上應(yīng)設(shè)置止回閥和升桿閘閥；使用蝶閥時(shí)，應(yīng)配備自鎖裝置；當(dāng)管徑大于DN300時(shí)，應(yīng)設(shè)置電動(dòng)閥（與進(jìn)水管相比）。
5. Check valve and rising stem gate valve shall be set on the outlet pipe of fire pump; When using butterfly valve, it shall be equipped with self-locking device; When the pipe diameter is greater than DN300, an electric valve (compared with the water inlet pipe) shall be set.
6、
川消消防泵應(yīng)能手動(dòng)和自動(dòng)啟停，并應(yīng)保證從收到泵啟動(dòng)信號(hào)到泵正常運(yùn)行的自動(dòng)啟動(dòng)時(shí)間不超過2分鐘。消防泵應(yīng)由消防水泵出水主管上設(shè)置的壓力開關(guān)、高位消防水箱出水管上的流量開關(guān)或壓力等開關(guān)信號(hào)直接自動(dòng)啟動(dòng)。報(bào)警閥開關(guān)。
6. Chuanxiao fire pump shall be able to start and stop manually and automatically, and the time from receiving the pump start signal to the normal operation of the pump shall not exceed 2 minutes. The fire pump shall be directly and automatically started by the pressure switch set on the main outlet pipe of the fire pump and the flow switch or pressure switch on the outlet pipe of the high-level fire water tank. Alarm valve switch.
7、消防泵在零流量時(shí)的壓力不應(yīng)超過設(shè)計(jì)工作壓力的140%；當(dāng)出水量為設(shè)計(jì)工作流量的150%時(shí)，出口壓力不應(yīng)低于設(shè)計(jì)工作壓力的65%。消防給水同一泵組內(nèi)的消防水泵型號(hào)應(yīng)相同，工作泵臺(tái)數(shù)不超過3臺(tái)。
7. The pressure of the fire pump at zero flow shall not exceed 140% of the design working pressure; When the water output is 150% of the design working flow, the outlet pressure shall not be lower than 65% of the design working pressure. The fire water pumps in the same pump set for fire water supply shall have the same model, and the number of working pumps shall not exceed 3.
此外，為適應(yīng)消防的需要，消防泵應(yīng)在結(jié)構(gòu)、抗腐蝕性能、機(jī)械性能、真空密封性能、連續(xù)運(yùn)轉(zhuǎn)性能、引水裝置等方面滿足要求，更為詳細(xì)的信息您可以關(guān)注我們網(wǎng)站
