Three screw pump assembly considerations.

3G three screw pump selection, as much as possible to understand the conditions of the pump in detail, in addition to operating parameters, such as flow, pressure to be clear, the characteristics of the medium transported, such as media corrosive, gas content and solid particle size, Medium temperature, viscosity, weight, etc. should understand. Three screw pump in China's oil, chemical, metallurgy, shipbuilding and other industries are widely used, the pump in many areas instead of centrifugal pump and gear pump. 3G triple screw pump has a long service life, high efficiency, low energy consumption, low noise, and so on. The insulation screw pump standard by GB10887-89 design. Three screw pump itself consists of only three screws, but there are a variety of structures, the general small flow, 0.2-6.5m3 / h pump body and bushing into a horizontal installation, shaft seal for the mechanical seal. Pump bushing above medium flow is fixed to the pump body as a separate part. Large flow pump made of double suction structure. Shaft according to the different media have a mechanical seal and packing seal two. The prime mover for marine pumps is AC marine motor. Three screw pump assembly considerations: 1, the assembly screw pump parts should be carefully cleaned, check, damaged parts should be replaced; 2, the drive shaft twenty thousand joint assembly, you should check the ring is damaged, in the air Cavity filled with grease; 3, the correct installation of bearings so that the shaft rotation flexibility, no jamming phenomenon. 4, shaft seal installation: packing box installed, the packing gland should be tight bolt position in the housing installation window, easy Wrench adjustment bolts; 5, the body pressed tight, the nut tightening should be uniform; 6, mechanical seal installation should be careful, friction deputy face should be clean and coated with grease; 7, Stator cavity surface, is conducive to stator installation; 8, installation and assembly, the coupling installation deviation △ Y ≤ 0.2mm, △ α ≤ 30 '.

Single Point Load Cells

analog single point load cells, also called platform load cells, are extremely versatile: With nominal load ranges from a few grams to a ton, high accuracies, and good dynamic weighing characteristics

What is a single point load cell?

Single Point load cells are a type of load cell, they are a very popular choice and account for the greatest percentage of load cells world-wide.

Single point load cells will offer high accuracy and high reliability, they are also known as [platform load cells" as this is their most common application. They are typically used in low capacity compact weighing systems.

Single point load cells are unique in that they can accept an off-centre load, this means that they will accurately measure weight if it is placed anywhere on the scale, therefore, allowing them to be highly precise in industrial applications.

Features of a single point load cell

Features of single point load cells will differ from cell to cell and will depend on the manufacturer but some of the most common features include;

  • High accuracy
  • High reliability
  • Protection rated (usually IP67, IP66 or IP65)
  • Usually constructed of alloy steel, stainless steel or aluminium

Features of the single point load cells we can offer;

  • Platform sizes from 200X200mm up to 1200X1200mm
  • Capacities from 300g to 2000kg
  • Many of our Single Point Load Cells also have OIML certification.

What is a single point load cell used for?

Most commonly, single point load cells are used in small to medium-sized scale applications. For example;

  • Counting scales
  • Balances
  • Pricing scales
  • Food scales
  • Industrial weighing
  • Packaging
  • On-board weighing
  • Medical weighing
  • Bag fillers
  • Retail
