Mobile museum strong shelving, also known as compact cabinets, is a high-density storage device designed for museums to store and manage a large number of cultural relics, artworks, и архивы. Mobile museum compact shelving is a rack with axle wheels installed on the base of a double-sided fixed rack. It can move in a straight line along a small guide rail laid on the ground. Multiple racks can be moved close to or apart from each other as needed, thereby achieving the purpose of efficient use of storage space. Однако, the maintenance of mobile museum compact shelving is a process involving multiple steps and precautions.

Mobile Museum Strong Shelves Repair

1. Maintenance steps

Troubleshooting

Observe whether the compact rack has obvious damage, such as scratches, износ подставки для ног и износ спинки сиденья, и поломка.

Check whether the operation is flexible and whether the components work well together.

Develop a corresponding maintenance plan by diagnosing the nature and location of the problem.

Разборка

Disassemble in the order of columns first and then racks. First remove the side panels of each column, then loosen the screws fixed to the column body and remove the column body from the track.

Be careful to stay safe during the disassembly process to avoid injury.

Уборка

Clean the disassembled parts to remove dust and dirt.

Be careful to protect the lines and equipment to avoid damage.

When cleaning, use a soft rag and avoid using rough cloth or detergent to avoid scratching the surface of the compact rack.

Repair or replace parts

Repair or replace damaged parts according to the problems found.

If the problem is caused by improper operation, such as the locking device under the crank is not open, it needs to be adjusted to the open state.

If it is a transmission device failure, such as a loose sprocket or a deformed hook, it is necessary to re-tighten the sprocket or contact the manufacturer to replace new parts.

Сборка

Reassemble the compact shelving in the reverse order of disassembly.

Ensure that the screws are tight, the transmission part is flexible, and the obstacles on the track have been cleared.

После сборки, check whether the components are well matched and whether the operation is flexible.

Acceptance

Acceptance is the last step of maintenance work and an important part of ensuring the quality of maintenance.

Check whether the overall appearance of the compact shelving is intact, whether the operation is flexible and reliable, and ensure that the compact shelving reaches the best storage state.

2. Precautions

Safe operation

Be sure to cut off the power supply of the compact shelving before maintenance to prevent electric shock accidents.

During the disassembly and assembly process, pay attention to personal safety and avoid injury.

Keep clean

Avoid using highly corrosive detergents when cleaning to avoid damaging the surface of the compact shelving.

Flange screw bearings, commonly referred to as flange bearings or flange mounted bearings, are used to support shafts and offer a secure mounting surface with a flange. There are several types, each suited to different applications.

Flange screw bearing type

1. 2-Bolt Flange Bearings

Описание: These have a circular flange with two mounting holes.

Common Use: Used in light-duty applications where space is limited.

2. 3-Bolt Flange Bearings

Описание: These have a triangular flange with three mounting holes.

Common Use: Provide a more stable mounting than 2-bolt versions, often used in agricultural and industrial machinery.

3. 4-Bolt Flange Bearings

Описание: These have a square or rectangular flange with four mounting holes.

Common Use: Used in heavy-duty applications due to their secure and stable mounting.

4. Piloted Flange Bearings

Описание: These have a central pilot that fits into a corresponding hole in the mounting surface for added alignment.

Common Use: Provide precise alignment and are often used in high-precision machinery.

5. Pressed Steel Flange Bearings

Описание: Made from pressed steel, these are lightweight and economical.

Common Use: Suitable for light-duty applications where cost is a concern.

6. Cast Iron Flange Bearings

Описание: Made from cast iron, these are more robust and durable.

Common Use: Used in heavy-duty applications where strength and durability are essential.

Spindle bearings are bearings installed on the spindle of a machine tool to support the spindle and bear the loads on it, including radial loads and axial loads. Its performance directly affects the machining accuracy, rigidity and service life of the machine tool. The assembly method of the spindle bearing varies depending on the bearing type, size and application scenario. The following is a detailed explanation of the assembly method of the spindle bearing. Let’s learn about it together!

Spindle bearing assembly method

1. Подготовка

Уборка: Перед установкой, use a special cleaning solvent to thoroughly clean the shaft, bearing seat and the bearing itself to ensure that there are no impurities, dirt and oil on the surface. This is to prevent impurities from entering the bearing and affecting the bearing performance.

Check the size and accuracy: Check the size and accuracy of the shaft and bearing seat to ensure that they meet the use requirements of the bearing. If the size or accuracy does not meet the requirements, it will cause the bearing to run unstably or even break prematurely.

Prepare tools and lubricants: Prepare the required installation tools (such as presses, pullers, special sleeves, п.) and lubricants (select grease lubrication or oil lubrication according to actual needs).

2. Installation steps

Place the bearing: Gently place the bearing on the shaft or bearing seat, ensuring that the bearing is fully aligned with the shaft or bearing seat. Avoid using heavy tools such as hammers to directly hit the bearing to avoid damaging the bearing.

Отрегулируйте клиренс: According to the type and size of the bearing, adjust the clearance of the bearing by adjusting the position of the bearing seat, adding or removing shims, п. Make sure the clearance is adjusted appropriately to ensure the normal operation of the bearing.

Fix the bearing: Use appropriate nuts, bolts or other fixings to fix the bearing on the shaft and bearing seat. When tightening the fixings, pay attention to the torque to be appropriate, neither too tight nor too loose.

А single-layer banana screen, also known as a multi-slope screen, is a type of vibrating screen that is widely used in mining, совокупность, and mineral processing industries. It is named for its banana-like shape, with multiple deck slopes that increase progressively from feed end to discharge end. This design helps to achieve higher throughput and more efficient separation.

Working Principle of Single Layer Banana Screen

Кормление

Material Introduction: The material is fed onto the screen at the feed end. The feed rate and material distribution are critical for efficient screening.

Initial Screening: The initial section of the screen deck is typically inclined at a steeper angle, which helps to rapidly stratify the material and initiate the screening process.

Вибрация

Vibratory Motion: The screen deck is vibrated using an eccentric drive mechanism. The vibration helps to move the material along the screen surface and separate particles based on size.

Амплитуда и частота: The amplitude and frequency of vibration are crucial parameters that influence the screening efficiency. They can be adjusted based on the material characteristics and desired separation size.

Процесс отбора

Multi-Slope Design: The banana screen features a series of decks with progressively decreasing angles. The top deck has the steepest angle, and the angle decreases towards the discharge end. This design helps to maintain a higher material velocity at the feed end and slower velocity at the discharge end.

Material Stratification: As the material moves along the screen, it stratifies, with finer particles moving towards the bottom and coarser particles remaining on the top. This stratification enhances the separation efficiency.

Разделение: The material is separated into different size fractions as it moves across the screen. The undersized particles pass through the screen apertures, while the oversized particles are discharged at the end.

Увольнять

Негабаритный материал: The oversized material that does not pass through the screen apertures is discharged at the end of the screen.

Undersized Material: The undersized material that passes through the screen is collected and can be further processed or sent to the next stage of the production process.
