How to improve the heat utilization rate of steam system, high pressure oil pump manufacturers to introduce to you

In the fire water supply system, the fire pump is the core. In the fire water supply system, setting fire standby pump can increase the safety of the whole system and improve the overall reliability of the fire water supply system. The standby fire pump is set in the fire water supply system. The main standby switch is an important means to realize the fire standby work after the fire pump is put into use, and it is also an important link for the safe and reliable operation of the fire water supply system.

Main and standby switch mode of booster oil pump fire pump:

In the design of pneumatic oil pump, there are mainly two main and standby switching modes of fire pump from the perspective of acquisition and control of fire pump start signal. The selection of control signal source is the key, which is divided into current signal control and pressure signal control. In general, the main and standby pumps of fire pumps need to be designed in the way of mutual standby pumps.

At present, the current signal control mode is commonly used in the fire protection design of vacuum pump. The system judges whether the fire pump works normally by the current signal feedback of the pump motor. When the motor is short-circuit (power-off) and the current is too high, the power supply will automatically switch to the motor of another water pump unit, stop the operation of one fire pump and start the operation of another fire pump.

The development and application of energy-saving technology for petrochemical pumps, steam system condensate recovery devices and other products were carried out. The key technologies such as high-efficiency hydraulic model and overall structure energy-saving optimization design were studied. The high-efficiency non overload hydraulic models such as centrifugal pump, mixed flow pump and tubular pump were conquered, and the key manufacturing process, wear-resistant material formula and sealing technology were solved The average efficiency of tower bottom pump, power station desulfurization pump and large tubular pump in oil refining unit is more than 5% higher than that of domestic similar products. Steam system steam trap condensate efficient recovery device, condensate recovery rate of 95%. The energy-saving products developed with this technology have been successfully applied in petrochemical industry, coal chemical industry, power station and East Route Project of South to north water diversion. Practice has proved that the research has positive significance for improving the utilization rate of heat energy in steam system, promoting the promotion and renewal of energy-saving products and technologies in steam pipe network system in China, and improving the recovery and utilization of heat energy in steam system.
