Fluorine plastic submerged pump failure reasons of sealing gasket

in fluorine plastic submerged pump, due to transport corrosive medium, once the sealing gasket failure, hazard. So, should attach great importance to fluorine plastic submerged pump sealing, to ensure that the fluorine plastic submerged water pump, and normal work.

if fluorine plastic submerged pump sealing gasket failure, the main factors are as follows:

1. Fluorine plastic submerged water pump pressure on the sealing gasket. Because of the sealing surface is always present small uneven phenomenon, sometimes some annular groove in the sealing surface processing. Be if seal to ensure that it is necessary to exert enough pressure sealing gasket, make its elastic or plastic deformation, to fill the gap.

a variety of gasket materials tightening force is usually given in plant samples or specifications sealing gasket, can also be confirmed through the test. Due to sealing gasket in the assembly process cannot meet the required tightening force, or due to due to vibration in the process of work make tightening bolt looseness and reduces the tightening force, due to the aging deformation of gasket materials lost its original elasticity, thus gasket failure and leakage will occur.

2。 pad internal structure or uneven thickness, choose with crack or crease the cardboard make gasket itself form a gap. When the gasket produce elastic deformation is not enough to fill the void, the leakage of the pump is not prevent.

3。 Fluorine plastic submerged pump gasket materials shall not apply to transport medium. Because of fluorine plastic submerged pump delivery of chemical products and chemical nature of diversity, in order to improve the combustion of the fuel value or change its combustion product, add a few in fuel additives, could change some features of the fuel. Therefore, it is not easy to pick and deliver the right gasket materials, and therefore is often due to incompatible, fluorine plastic submerged pump gasket caused by wear and leakage phenomenon.

in pump gasket selection, installation, protection and protection in the process, it is necessary to strengthen the consciousness of produce and prevent water pump gasket failure.

it is a kind of corrosion resistance of vertical pump, its flow components submerged in the transport medium, the shaft through the bearing parts and bearing parts remain stable, the weight of the pump and axial force through the bearing to the foundation, according to the requirement of processing device, fluorine plastic should be submerged pump must be in depth. The structure design of the pump is mainly consider the following two elements:

the temperature of the pumped medium resolution the types of stents, cooling structure, insulation sleeve and so on. Accordance with the requirements of the use of the pump, can rationally recognize into the depth of the pump body, to the fluorine plastic submerged pump can start at any time, into the depth of the pump body is necessary is long enough, the liquid level in the pump body, to ensure that the fluorine plastic submerged pump can be launched at any time, such as sulfuric acid from pump and fluorine plastic submerged pump for the hydrogenation of exercise; Described are the requirements for the use of fluorine plastic submerged pump launch a fluorine plastic submerged pump, and stop after absorbing water.
