Tank Weighing | Collection of Common Problems
Date: 2024-12-03Read: 9
Whether it is raw material storage or proportioning, automated production or manual production, material tank weighing has become an indispensable part of modern industrial production.
Are you also struggling to configure the material tank weighing system?Do installation kits need to be equipped with horizontal tie rods? Is it necessary to have an upper and lower transition plate? How should the material tank pipeline be designed?
Xiaoyin has collected some common questions raised by customers in the actual configuration of material tank weighing. Let's take a look together~
Question one
What situations require horizontal and vertical pull rods?
Longitudinal pull rodIt is an anti overturning design that ensures the safety of the material tank under extreme conditions (such as earthquakes). Conventional material tank sensor installation kits should be equipped with longitudinal pull rods.
Horizontal pull rodMainly used to reduce the impact of lateral displacement on sensor accuracy. When the material tank is equipped with a stirring device, especially when mixing viscous and granular materials, a transverse pull rod design should be added. For environments with high vibration, lateral pull rod design can also be considered. There is no need to add a horizontal tie rod design when there is no mixing and the material tank is relatively stable.

Question Two
When do I need to configure the upper and lower transition plates?
When the support legs or ears of the material tankWhen installation holes are not reserved according to the installation kitNeed to add upper and lower transition plates. The upper transition plate is directly welded to the tank leg or support ear, and the lower transition plate is welded to the on-site foundation embedded plate to prevent displacement during use.
Do notWelding the installation kit to the on-site support ears or foundation embedded plates in the absence of bolt fixation and upper and lower transition plates can pose difficulties for later maintenance and adjustment.

Problem Three
What should be noted in the structure and pipeline design of the material tank?
The position of the material tank should be as far away from the vibration source and frequency converter as possible; The foundation requires a flat surface, a tilt angle of less than 0.5 °, and sufficient strength to not bend under load. The material tank should be placed on an independent bracket to avoid the readings being affected by another material tank.
The pipeline design follows the principles of small quantity, small diameter, priority for horizontal direction, and symmetrical distribution. The fewer connections, the better the degree of freedom of the material tank. Each pipeline must contain a flexible insert with a horizontal section, and the length of the flexible insert depends on the elasticity of the material. Try to reserve 20-30 times the diameter of the pipeline for the length of the hose.
Question Four
Common problems and solutions in practical applications
More than 90% of the problems on site are caused by the limit bolts not being adjusted properly, resulting in stress and causing errors.Timely check the limit boltIs it stuck,Ensure that the horizontal tie rod is in an active state.
Foundation issues are also one of the reasons for inaccurate weighing, especially when sensors are installed on steel plates or frames in large material tanks for weighing. After loading materials, the foundation deforms, which affects the accuracy. At this time, the weighing sensor needs toIncrease vertical support strength.
For high-temperature materials, the thermal expansion and contraction of pipelines (especially for hoses wrapped in steel mesh) can easily generate stress, affecting system accuracy and leading to irregular and unstable readings on site. at this momentShould be adoptedA hose design that is not affected by thermal expansion and contraction,Increase the length of the hoseTry as much as possibleIncrease the horizontal arc length.
