Fire pump manufacturers: to introduce you how to buy fire pump

Fire pump is divided into vertical fire pump and horizontal fire pump, the flow of liquid is one of the important performance data of the choice of fire pump. The flow of conveying liquid is directly related to the production capacity of the whole device, so the choice of fire pump above, pay attention to the flow of fire pump, the size of the flow will affect the efficiency of the fire pump. When buying fire pump flow and head is an important standard, the second advantage of fire pump lies in its attention to energy saving and environmental protection. Because water is a valuable resource, the pump can save water under the premise of its good performance and humanity. When buying a fire pump, a very important point is the choice of model. The fire pump should be selected according to the height of the floor and the water flow required in the room. According to the power, speed, etc., choose the right head, and strict control of quality, in line with the national quality inspection standards.

1. Simplify installation In the case of natural circulation, the circulating pressure of the system is due to the poor specific gravity of the water. The circulating pressure produced is usually only a few thousandths of the atmospheric pressure. Therefore, the existence of bubbles in the system will seriously hinder the realization of circulation. After using the circulating pump, heating installation is greatly simplified. 2. Arbitrary layout In the case of natural circulation, in order to ensure the circulation pressure of the system, the radiator and the cooker are separated from the necessary distance in the direction of gravity, resulting in "the radiator hanging high" or "the stove falls into the ground" and other problems. Using forced circulation, without considering the relative position of radiator and furnace. Even if the furnace is higher than the radiator, it will not affect the circulation of the system. Circulating pump 3. Optimize the system Because the power of natural circulation is very small, a very thick main pipe is usually used to reduce the resistance of the system. Even so, the system often has problems with circulation or heat dissipation. After the use of the circulating pump, the main diameter can be reduced appropriately, so as to simplify the installation, optimize the circulation, beautify the appearance. 4. Save money The disadvantage of natural circulation is the low efficiency of the radiator. Under normal conditions, the temperature difference between the top and bottom of the radiator is more than 40 degrees. The forced circulation can reduce the temperature difference between the radiator and the radiator. Based on the same heat dissipation calculation, it is estimated that the radiator can save 20-30%. In addition, each system can achieve considerable cost savings due to reduced mains power.

In both north and south, the temperature always drops very quickly in the middle of winter. When the temperature drops, the important thing is to heat it up. Although there are many methods of heating, it can be used in many places. In fact, floor heating is a special case. Not only is the heating form good, but the price is not expensive, so is the heating and circulation pump useful? Floor heating and circulation pump are useful. When the local heating pipe pressure is not stable or the water circulation is not good, you can install the floor heating circulation pump. It can improve the water flow velocity in the floor heating pipe, improve the heating efficiency and make the indoor temperature rise. Circulating pump 1. As the name suggests, install a heating circulation pump on the heating system to increase the pressure of the system, increase the flow of heating hot water, and then increase the heat dissipation of the radiator to increase the indoor temperature. Circulating pumps are mainly aimed at self-heating users, or circulation of large and medium-sized home heating systems. 2. Floor heating and hot water circulation. If the inlet temperature is acceptable and the outlet temperature is low, installing a circulating pump can solve this problem, but if the inlet and backwater temperatures are low, it is also useful to install a circulating pump when the heating is not hot. Generally, the pump is installed on the backwater line, a section of pipe is removed from the original system, and the pump is connected to the pipe.
