PHP系列平衡式比例混合裝置Foam Pump Proportioning System

自動或手動啟動消防泵組提供供水壓力同時(shí)啟動齒輪泵組，通過泡沫液泵把泡沫液加壓后與壓力水供給的壓力反饋給平衡閥，自動調(diào)節(jié)閥門開關(guān)大小達(dá)到動態(tài)平衡。使一定量的泡沫液與壓力水進(jìn)入比例混合器，形成泡沫混合液。如果進(jìn)水管道的壓力和流量出現(xiàn)比例不穩(wěn)定時(shí)，平衡閥通過動態(tài)平衡調(diào)節(jié)進(jìn)入比例混合器的泡沫液量，使泡沫混合液比例準(zhǔn)確，從而保證裝置在運(yùn)行過程中源源不斷地配置成較為精確混合比的泡沫混合液，供泡沫滅火設(shè)備進(jìn)行有效的滅火。儲存泡沫液的常壓罐在工作時(shí)可以添加泡沫液,使滅火時(shí)間延長,提高了滅火抗災(zāi)的能力。

Foam pump proportioning system is the unit to supply foam solution for foam system. The system mainly consists of atmospheric foam tank, foam pump, power unit, balance valve, proportioner, control valves and control system. Foam pump draw out foam concentrate from the tank and it will mix with water in proportioner. The pressure of water and foam solution will be feed back to balance valve. Balance valve will adjust the amount of foam concentrate to reach dynamic equilibrium to guarantee an accurate mixing ratio.

產(chǎn)品分類Category

根據(jù)泵的驅(qū)動方式的不同，該裝置可分為電機(jī)驅(qū)動型、水輪機(jī)驅(qū)動型和柴油機(jī)驅(qū)動型或兩者配合使用。

The unit can be classified into motor driving, water turbine driving, diesel driving or the combination of two of the power according to power source of foam pump.

電機(jī)驅(qū)動型

由電機(jī)帶動齒輪泵轉(zhuǎn)動，把泡沫液加壓后進(jìn)入平衡閥，通過平衡閥調(diào)節(jié)后，進(jìn)入比例混合器。雙電機(jī)型設(shè)備如果其中一臺發(fā)生故障，另一臺備用泵自動切換運(yùn)行，從而保持正常工作狀態(tài)。

Motor Driving

This model drives foam pump with a motor. There are two motors available that if one of them is broken down, the spared one can still guarantee the system keep normal operation
