IMO screw pump It is a kind of pump used to transport high temperature, high pressure and high viscosity media. It has the characteristics of strong conveying capacity, good corrosion resistance, high stability, etc. In order to ensure the normal operation of the pump and extend the service life of the pump, it is very important to select a suitable sealing method. Here are some choices for IMO Screw pump Common sealing methods of.

Simple packing seal: simple packing seal is one of the most common sealing methods, which is composed of packing ring and packing chamber. The sealing is realized by the close contact between the packing ring and the shaft sleeve. The selection of filler shall be determined according to the characteristics of the medium and working conditions. For high temperature, high pressure and high viscosity media, high temperature, corrosion resistant and abrasion resistant fillers are usually selected.

Mechanical seal: mechanical seal has the advantages of good sealing effect and long service life. It is composed of a fixed ring, a movable ring and a packing chamber, and is sealed by the friction between two ring surfaces. When selecting the mechanical seal, the seal material and model shall be determined according to the characteristics of the medium and working conditions. For high temperature and high pressure media, mechanical seals that are resistant to high temperature, high pressure and corrosion are usually selected.

Magnetic seal: magnetic seal is a non-contact sealing method, which isolates the rotor and stator through the magnetic field to achieve a leak free sealing effect. Magnetic seal is applicable to the transportation of high temperature, high pressure, toxic and harmful media. It has the advantages of good sealing effect, long service life, simple maintenance, etc. IMO agent

Diaphragm seal: Diaphragm seal is a common sealing method, which separates the pump from the outside through the diaphragm to prevent medium leakage. Diaphragm seal is suitable for media with high viscosity and easy crystallization, and has the advantages of simple installation and convenient maintenance.

Piston ring seal: piston ring seal is a common sealing method, which is composed of piston ring and packing chamber, and is sealed by the close contact between piston ring and shaft sleeve. The piston ring seal is suitable for the transportation of high temperature, high pressure and high viscosity media, with good sealing performance and long service life.

When selecting the sealing method suitable for IMO screw pump, the following factors need to be considered:

Characteristics of conveying medium: including temperature, pressure, viscosity, corrosivity, etc. Different media have different requirements for sealing materials and structures, and the sealing method needs to be selected according to the actual situation.

Working conditions: including the working temperature, pressure, speed, etc. of the pump. Different working conditions have different requirements for sealing materials and structures, so it is necessary to select suitable sealing methods.

Maintenance and replacement costs: different sealing methods have different maintenance and replacement costs, and the convenience and cost of maintenance and replacement need to be considered.

Service life: different sealing methods have different service life, so it is necessary to consider the impact of service life on the whole operation cycle.

In a word, the selection of sealing method suitable for IMO screw pump requires comprehensive consideration of factors such as medium characteristics, working conditions, maintenance and replacement costs, and service life. Choosing a suitable sealing method can improve the working efficiency of the pump, extend the service life of the pump, and ensure the normal operation of the pump. ALLWEILER screw pump
