Pay attention to the suitability of choosing ppe

Fire pump selection method 1. High-efficiency, low-noise, energy-saving centrifugal pumps should be selected, and the elimination of products should be strictly prohibited.

Fire pump selection method 2, should be based on the design flow, the required lift pump selection, and consider the pump due to wear and other causes of the pump output decreased, the slurry pump can be calculated by the head H multiplied by 1.05 ~ 1.10 coefficient after the pump; should be selected The characteristic curve is the pump whose head decreases gradually as the flow rate increases. Such a pump is stable in operation and reliable in parallel operation; and the operating point of the pump should be maintained in an efficient range, which is not only energy-saving but also less likely to damage the parts.

Fire pump selection method 3, when there is no adjustment of the water supply network, it should adopt speed control pump group or rated speed pump group running water supply. The maximum output of the pump group should not be less than the design flow of the community water supply, and should be checked with fire conditions.

Fire pump selection method 4, choose the water tank, water tower lift pump should minimize the number of pumps, should be used with a preparation; when a single pump can meet the requirements, it is not appropriate to use more than one parallel mode; if you must use more than one parallel operation or When the size of the pump is matched, the centrifugal pump type and the number of the centrifugal pump should not be too much. Generally, the number of models should not exceed two. The head range of the single-stage clean water centrifugal pump should be similar; each pump should be operated in the high-efficiency range in parallel operation.

Fire pump selection method 5, Frequency control pump design Water supply flow should be guaranteed to meet the requirements of the maximum design seconds flow in the living water supply system. The power of the slurry pump must be reliable; the working point of the pump should be selected in the efficient working area of ​​the pump characteristic curve, and should not be selected on the extended line of the QH curve. The most unfavorable working point of the design should be at the right end of the high efficiency section of the pump characteristic curve. Point, that is, the point where the pump has the largest amount of water and the lower head but meets the requirements, that is, the intersection of the low point of the high-performance area of ​​the pump characteristic curve and the pipe characteristic curve. The range of water pump speed regulation can be as far as possible in the high-efficiency section of the pump; the speed range should be set between 25% and 100% of the pump water supply; the equipment should have the water level automatic control function.

Fire pump selection method 6. The multi-stage pump unit of the life pressurized water supply system shall be provided with a standby pump. The water supply capacity of the standby pump shall be greater than the water supply capacity of the largest one. The pumps shall be switched automatically and operated alternately.

Fire pump selection method 7. The voltage of the motor equipped with the centrifugal pump should be the same, and the power supply system should be the same as the national grid power supply system.

High-definition monitoring For the switch selection, it is simple and simple. It is complicated and complex. Many people think that they need strong professional knowledge. Actually, they still need rich experience. Feng Runda, a provider of transmission products & services, combined with different monitoring scales, provided the choice of switches and related experience.

First, the factors that affect switch selection
1, Resolution The common resolution of the camera is 720P, 960P, 1080P... 4K, the large resolution means a large amount of data, which means that the larger the code stream, the greater the required network bandwidth.

2. Coding Protocols In this paper, the H.264 compression encoding protocol has been released based on H.264. However, the mainstream H.264-based devices currently use H.264 as the main reference.

3, bandwidth needs to know is that even if the resolution and coding protocol of the two cameras are the same, but due to the different manufacturers, the code stream of the two videos may be several times different.

    The die casting process involves the use of a furnace, metal, die casting machine, and die. 

    The metal, typically a non-ferrous alloy such as aluminium or zinc, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting parts. 

    The castings that are created in this process can vary greatly in size and weight, ranging from a couple of ounces to 100 pounds. One common application of die-cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior. 

    Metal housings for a variety of appliances and equipment are often die cast. 

Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Most home appliances also need lightweight and firm aluminum die casting parts, like bracket, heat dissipation module or structural support. Other common die cast parts include propellers, gears, bushings, pumps, and valves.
