Multi-level submerged pump should be how to choose

multi-level submerged pump transporting medium temperature and everybody attaches great importance to the problem, this is related to the transport medium and used in the industry. Then the pump is generally can transport medium containing a small amount of solid particles or impurities, water pump transporting temperature of 0 ~ 105 ℃, the temperature in the 20 ~ 10 ℃ and 105 ~ 180 ℃ can choose insulation jacket and cooling jacket, choose low or high temperature resistant guide bearing, so that users need to clarify to the manufacturer.

how to choose the suitable for multi-level submerged pump?

1, medium can be tentatively identified types, such as slurry pump or water pump, whether the presence of corrosive medium, choose the suitable materials.

2, the depth of the pool and operating conditions, confirm the length and structure of multistage fluid way, or appropriate for bottom pump suction.

3, flow to confirm delivery of pipe diameter, spacing and height difference reconfirm lift.

multi-level submerged pump selection basis should be based on technological process, water supply and drainage requirements, shipping quantity from liquid head, liquid properties, pipeline settlement, equipment and operating conditions five aspects into consideration.

1, the traffic is to choose one of the most important function of multi-level submerged pump data, it is directly related to the ability of production and delivery of the equipment. Optional water pump, based on large flow, normal flow, give attention to two or morethings without large flow, usually desirable to normal flow rate of 1. 1 times as a larger flow.

2, fluid properties, including liquid medium title, physical properties, chemical properties and other properties of the solid particles in the medium diameter and gas content, etc. , which involves the system of the head, a gas corrosion allowance calculation and appropriate pump type: chemical properties, mainly refers to the chemical corrosion resistance and toxicity of liquid medium, is made of multistage liquid pump data and choose the kind of shaft seal type of important basis.

3, multistage pipeline settlement conditions of submerged pump equipment system refers to the liquid height conveying liquid from liquid to, head of accounting for system and NPSH of checking.

4, the required lift equipment system is another important function of submerged pump, general to use increase 5%, Head to selection after 10% allowance.

5, many multi-level submerged pump operating conditions, such as operating T full steam power, discharge side of the liquid container pressure, elevation, environment temperature operation is the gap is still in succession, the orientation of the pump is fixed is still can be moved.
