In the work of sand mining pump and sand ships, sand mining pump pipelines are indispensable. For example, rubber pipes required for import and export, PE pipes for long-distance transportation and rubber short pipes connecting PE pipes, etc. So how to choose various dredging pipelines? This article will introduce you to how to select and configure the appropriate sand dredge pump pipeline.
1. How to choose the sand delivery pipe of the sand mining pump?
A. Sand mining pumps generally use steel pipes or HDPE pipes.
Steel Pipes:
Steel pipes are commonly utilized in scenarios involving close range or high pressure applications. These pipes endure significant pressure, whether from external or internal sources, making them more resilient compared to other plastic materials. They can be conveniently cut and welded on site, facilitating ease of use. Steel pipes boast a high recycling rate, retaining value even after project completion, and can be resold at competitive prices. Additionally, they can be repurposed for various other applications.
HDPE Pipes:
HDPE pipes find predominant use in situations requiring long-distance sediment transportation. Featuring a smooth inner surface with a Manning coefficient of 0.009, HDPE pipes offer superior performance. Their non-adhesive properties result in heightened conveying capacity compared to conventional pipes, thereby reducing pressure loss and energy consumption during water conveyance. Furthermore, pipes constructed from new PE material exhibit exceptional wear resistance.
In mud transportation applications, HDPE pipes outshine steel pipes in wear resistance, promising extended service life and enhanced cost-effectiveness. These pipes exhibit remarkable aging resistance, ensuring a prolonged lifespan. Polyethylene pipes containing evenly dispersed carbon black (2-2.5%) can withstand outdoor storage or use for up to 50 years without succumbing to damage from ultraviolet radiation. Their lightweight nature makes them easy to transport and disassemble. Given these advantages, HDPE sand discharge pipes are typically recommended for optimal performance.
B.Small sand mining pumps (pumps with specifications below 11kW) generally use hoses with steel wire linings for drainage
Therefore, when the pump of this specification leaves the factory, the water outlet is equipped with a hose joint, and the user only needs to put the hose on the hose joint, and then fasten it with a pipe hoop or iron wire. If the user chooses the steel pipe, he can directly weld the steel pipe to the hose joint, or remove the hose joint and match the flange separately. If the user chooses a hose, be sure to match the hose that meets the pressure requirements, otherwise it will burst open. For high-pressure hoses, both ends of the hose are provided with steel flanges, and the flanges connected to them must match the flange standards of high-pressure hoses.
2. How to choose the sand suction rubber hose for the sand mining pump?
In the actual application of the project, the general sand suction pipe is used in conjunction with a steel pipe and a rubber hose. Special attention should be paid to the rubber hose. Be sure to use a hose lined with steel wire or steel ring to withstand negative pressure and prevent it from being sucked when it absorbs water.
At present, there are only a handful of China manufacturers that can produce high-quality large-diameter sand suction hoses, so be careful when purchasing. It is recommended to purchase together with the sand mining pump. When configuring the sand suction pipe, the diameter of the pipe should be the same as or larger than the diameter of the sand outlet pipe (not too large). The length of the suction pipe should be as short as possible. Too long straws can lead to reduced efficiency and cavitation of the sand mining pump.
3. The soft joint of the sand mining pump
Soft joints are also called rubber hose soft joints, rubber joints, rubber soft joints, flexible joints, high pressure rubber joints, rubber shock absorbers, etc. Soft joint is a hollow rubber product used for flexible connection between hard pipes. This product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes. It is widely used in various pipeline systems. The soft joint also facilitates the disassembly and assembly of the sand pump. A soft joint must be installed at the inlet and outlet of the sediment pump. On longer pipelines, they should also be installed at intervals.
The diameters of the sand discharge pipe, sand suction pipe and rubber hose soft joint should be selected according to the design parameters of the sand pump. When the sand pump leaves the factory, we generally recommend the matching diameter, and do not change it any more. The pressure of the pipeline must also be able to withstand the maximum pressure of the sediment pump.
4.The Flange of the sand mining pump
Flange connection is to fix two pipes, pipe fittings or equipment on a flange first, add flange pads (usually rubber) between the two flanges, and fasten them together with bolts to complete connected. Some pipe fittings and equipment already have their own flanges, which are also flanged connections. Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand greater pressure. The pipeline flange of the sand mining pump is generally made of plate-type flat-welded steel flange, the national standard (GB/T9119-2010), which is suitable for pipeline connection with a nominal pressure not exceeding 2.5MPa. The selection of flanges should also be considered consistent with the national standards for pipelines.
