What kind of pump is used for long-distance pumping, what kind of self-priming pump is used for long-distance pumping, what kind of water pump is used for long-distance pumping
First, long-distance pumping pump product overview
Long-distance pumping in the pump suction pipe beyond 20 meters are long-distance, because the conventional self-priming pump due to the limited self-priming capacity of the case, self-priming pump suction pipe can not be more than 20 meters because the pipeline is too long after the pipeline will be a lot of air, due to the self-priming pump pumping its own air exhaust capacity is slow, the pump runs for a long time after the pump temperature of the liquid inside the pump will rise after the temperature is high after the self-priming pump self-priming performance will fall, so it is difficult to suck the liquid over, then long-distance pumping, what kind of pump is used for long-distance pumping? Decrease, so it is difficult to suck the liquid over, so what is a good pump for long-distance pumping? On this issue, we will share with you what pumps are good for long-distance pumping according to various working conditions.
Second, what is a good pump for long-distance pumping
1, if you need the flow in 3-800m3 / h recommended the use of ZW self-priming sewage pump on the basis of adding a set of vacuum auxiliary system of long-distance pumping products, the horizontal distance can be sucked to about 150 meters (according to the required flow rate and inlet pipe material and caliber, you can calculate the loss), a single self-priming height of 8 meters, if you need to reach 9 meters can be specially customized. My company's all ZW self-priming sewage pump products can be made into 5 blades of open impeller structure, open impeller long-distance pumping anti-clogging effect than the ordinary self-priming sewage pump anti-clogging effect of a lot of excellent, choose a few low-speed pumps can be used as a pumping thick slurry, slurry, suction manure and other purposes.
Need to understand the relevant performance parameters can refer to: self-priming sewage pumps
2, if you need a larger flow rate of 100m3 / h to 2600m3 / h, and the requirements of the self-priming pump itself suction is greater, the transport of the liquid inside the diameter of solid particles, such as the requirements of the 6-inch self-priming pump through the diameter of the solid particles can be passed through the 75mm or so, it is recommended to use the new vacuum-assisted high suction self-priming sewage pumps, the impeller using a 3-bladed impeller, 3-blade impeller than the 5-blade impeller. Impeller than the 5-piece impeller self-priming sewage pump through the solid particles stronger.
Especially used in the flood control and rescue industry using the series of self-priming pumps such as the selection of the flow rate of 1000m3 / h can be inlet pipe from a 300 to 2 250mm suction port, the outlet from a 300mm to 4 150mm, if in the event of flood control and rescue operations, the special trucks to go to the place can be used in the multiple intake pipe connected together for pumping distance Distant water, and can also be the pump inlet pipe with a boring plug off a suction port, the outlet pipe with a boring plug off 2, so that you can use all the pipeline to a suction port to achieve the purpose of long-distance pumping, DN250 pipeline 100 meters long, we calculate in accordance with the flow rate of 500m3 / h, corresponding to the plastic pipe fluid flow rate in 2.82m / s, the pipeline loss of 2m along the way, the 100 m of the DN250 pipeline volume formula for 0.125 * 0.125 * 3.14 * 100 = 4.90625m3, normal 1000m3 / h vacuum-assisted self-priming pump is configured with a vacuum pump pumping capacity of 63m3 / h, according to this rate we can calculate that it takes about 4-5 minutes to 100 meters of pipeline air pumping clean so that the liquid is sucked into the self-priming pump Inside, if the self-priming pump pre-added part of the liquid and the vacuum pump at the same time together to start so that the self-priming time will be shortened by 100 meters distance in about 2 minutes can be pumped over the water.
