Portable Fire Fighting Pump Manufacturer:What are the advantages of pumps?

Diesel pump is a pump powered by diesel engine, which completely reduces the labor intensity of workers, and it is convenient to use, move, install, less maintenance and stable performance.

The advantages of diesel pump compared with ordinary centrifugal pump are as follows:Portable Fire Fighting Pump Manufacturer

(1) to the production of diesel engine pump can meet the need of diesel engine technology, not only to transport liquid materials and provide the necessary pressure process requirement, also must ensure that the amount of material conveying, in a diesel engine unit operation, the requirement of pump flow (unit: cubic meters per second) and head to stability, keep the pump efficiency and reliable operation.Portable Fire Fighting Pump Manufacturer

(2) Corrosion resistant diesel engine pump delivery medium, including raw materials, reaction intermediates are often corrosive medium. Electric pump is a kind of mechanical and electrical integration equipment which is directly driven by diesel engine and can start and realize water supply in a short time. This requires that the material selection of the pump is appropriate and reasonable to ensure the safety, stability and long life of the pump.

(3) High temperature resistant, low temperature diesel engine pump delivery of high Portable Fire Fighting Pump Manufacturer temperature medium, there are flow liquid materials, but also the reaction process needed and produced heat liquid. For example, condensate pump, boiler feed pump, and thermal oil pump. Diesel engine pump delivery of low temperature medium types are also many, such as: liquid oxygen, liquid nitrogen, methane, etc., the low temperature pump operating temperature is mostly in a 20~ 10℃. Regardless of the transmission of high temperature or low temperature diesel pump, material selection and structure must be appropriate, must have enough strength, design, manufacture of pump parts can heat shock, thermal expansion and low temperature cold deformation, cold brittleness and other effects.

(4) Wear resistance, erosion resistance because the logistics of diesel pump contains suspended solid particles, at the same time, the impeller and cavity of the pump also work under high pressure and high velocity, the protective layer of the pump parts is destroyed, and its life is short, so it is necessary to improve the wear resistance and erosion resistance of the diesel pump. This requires the material of the pump to choose wear-resistant manganese steel, ceramic (raw materials: non-metallic minerals), cast iron, etc., the selection of scour resistant titanium, manganese steel, etc.

(5) Reliable operation of diesel pump operation reliability includes two meanings: one is a long period of operation without failure; Second, various parameters are stable in operation. The reliability of operation is very important for diesel engine production. If the pump often failure, not only will cause often stop production, affect output and economic benefits, and sometimes also may cause the diesel engine system accident. The fluctuation of diesel pump speed will cause the fluctuation of flow and pump outlet pressure, so that the diesel engine production can not be carried out normally or the reaction in the system is affected, the material can not be balanced, not only cause waste, even cause the Product quality decline or make the Product scrap.

(6) without leakage or leakage of the diesel engine pump medium mostly less flammable, explosive, toxic and harmful liquid, once the leak will seriously pollute the environment, endanger personal safety and health of body and mind of the worker, the more don’t accord with the requirement of no leak factory clean and civilized factory, it must ensure that the diesel engine pump run time does not leak, on the sealing of pump adopts new technology, new material, Operate according to procedures and maintain with high quality.

(7) can transport the critical state of liquid critical state of liquid, when the temperature increases or the pressure decreases, tends to vaporize. Electric pump is a kind of mechanical and electrical integration equipment which is directly driven by diesel engine and can start and realize water supply in a short time. Diesel pump sometimes delivers critical liquid, once the liquid vaporizes in the pump, it is easy to produce cavitation damage, which requires the pump to have high cavitation resistance performance. At the same time, the vaporization of the liquid, may cause the friction of the dynamic and static parts of the pump, which requires the clearance to be larger. In order to avoid the destruction of mechanical seal, packing seal, labyrinth seal due to dry friction due to the vaporization of liquid, this kind of diesel engine pump must have the gas in the pump to fully exclude the structure.
