The diesel engine fire pump has high efficiency, reliable operation and flexible installation form. It can be used as a backup fire pump to ensure the fire protection needs without power. When the fire is not powered, it can be started automatically. It can be combined with the electric pump group and the constant pressure pump to form an automatic fire protection. The water supply system can be controlled jointly with the fire protection center.
Diesel engine fire pump industry and civil building fixed fire protection system, including water supply for fire hydrant, fire extinguishing system, automatic sprinkler system and water spray fire extinguishing system, can also be used for domestic water boosting. When the unit is automatically controlled, the diesel engine fire pump realizes the functions of automatic system, input, automatic switching, automatic protection, etc., and can also interface with the user fire center or automatic fire alarm device to realize remote monitoring. In order to ensure the normal operation of the unit under the environment of 5 ° C, the unit can be equipped with a cooling water preheating heating device.
The water injection mode of diesel engine fire pump has two types: self-irrigation and suction. According to the requirements of fire protection regulations, it is generally self-irrigating water diversion method. It is mainly composed of diesel engine, fire pump and control system, which meets the requirements of automatic diesel engine fire pump group. Various functions and requirements -. The diesel engine fire pump has a fully automatic control design, with manual control, automatic program control, remote control, forced start and other selection control modes.
The diesel engine fire pump constant pressure fire extinguished the constant speed control mode of the conventional fire protection system. By configuring the speed PID adjustment ring and the pressure PID adjustment ring for double loop control, the constant pressure water supply was realized accurately, smoothly and quickly, and the fire protection was effectively protected. The personal safety of the personnel has improved the fire extinguishing effect. The diesel engine fire pump is easy to operate, and the program parameters can be set through the man-machine interface; the pump outlet pressure value can be set by the user. When the commissioning work is completed, the daily fire signal can automatically start the fire-fighting unit without manual operation.
The diesel engine fire pump system provides three-way temperature control device for room temperature, water temperature of the tank and water temperature of the pipeline system. It can automatically start and stop the heating according to the feedback information of the temperature sensor, keeping the temperature control points within a certain range, effectively preventing water from freezing, ensuring that the water is frozen. The fire protection system is ready for operation. The diesel engine fire pump automatic charger ensures that the engine has a full voltage ignition start at any time; the fully automatic battery charger has the characteristics of constant voltage, constant current, turbulence and short circuit resistance.
The diesel engine fire pump is equipped with a remote control communication port, which is connected with the computer and can display various states such as alarm, protection, fault signal, etc., to realize remote comprehensive monitoring of the unit operation, and can be equipped with a fully automatic vacuum water pump to realize self-priming function. External power, the water automatically detaches after it is brought up. The diesel engine fire pump can be controlled manually or automatically. The user can choose the control mode by himself. It can be realized by adding a mixer outside the pump. The user can choose whether to mix foam or foam.

Our key products are litharge using in assaying of precious metal, and lead nitrate using in gold mining. Lead nitrate is used as medical astringent; tanning material for leather-making; dyeing mordant; photograph promoting agent; flotation for ore; chemical reagents; and also used for making fireworks, match, and other lead salts. In the mean time, we are sourcing the other chemical reagents for our mining customers in Australia, Canada, Africa etc.
1. Product name:lead nitrate
2. Character: white crystal powder, relative density 4.53(20), easily soluble in water, liquid ammonia, light dissolve in ethyl alcohol, not dissolve in concentrated nitrate acid, solubility 56.5g/100g water (20). Dry lead nitrate decompose at 205-223. Damp lead nitrate decompose at 100, first become Pb(NO3)2 . PbO, go on heating, then become PbO. It is strong oxidant, putting together with organics will lead it burning, noxious.
3. Application: Used as flotation reagent for gold ore and other ore.
