Brush Seal

What Are Brush Seals?

Brush seals are devices used to seal the gap between the rotating shaft of a machine and its bearing.

They adhere and seal the gap between the brush and the bearing under pressure applied between them, ensuring a tight seal between the shaft and the bearing. The operating principle is simple: pressure is applied from the outside between the brush and the bearing, causing the brush to adhere to the bearing and seal the gap between the rotating shaft and the bearing. This prevents external foreign matter such as dust from entering the machine’s interior and effectively retains lubricating oil.

The structure mainly consists of brushes and bearings, characterized by high sealing performance and durability. This design makes them suitable for various fields, including industrial machinery, automotive, and household appliances. Brushes can withstand wear and damage, and regular inspection and replacement are easy.

Bonded Seal

What Are Bonded Seals?

Bonded seals are seals made by bonding metal and rubber.

Utilizing the characteristics of both metal and rubber, they offer high sealing performance and durability. The operating principle involves pouring rubber onto the surface of the metal, adhering it, and sealing through the pressure difference between the metal and rubber. Through this process, the rubber adheres to the metal, deforms under pressure, eliminating gaps, and seals.

Bonded seals are used in various applications such as hydraulic equipment, plumbing, piping, automotive parts, and machinery components. Their features include high sealing performance, durability, heat resistance, chemical resistance, lightweight, and compactness. However, it’s important to note that inadequate bonding between the metal and rubber can lead to decreased sealing performance, and there is a risk of adhesive failure under high temperatures or pressures, requiring caution during use.

Bin Container

What Is a Bin Container?

A bin container is a type of container equipped with multiple storage compartments.

It is designed for the transportation of heavy materials such as steel, cement, and wood, and typically comprises two main components: an outer box and internal storage compartments. Key features include the efficient transportation of multiple items simultaneously and the ability to withstand heavy loads. Moreover, the independent nature of the storage compartments makes loading and unloading straightforward.

Primarily used for the transportation of heavy materials, its operational principle aligns with that of conventional containers, requiring forklifts or cranes for loading and unloading. There are payload and size limitations associated with the storage compartments, which need to be verified. Additionally, safety precautions should be followed during the loading and unloading processes.

ACME Screw

What Is an ACME Screw?

An ACME screw is a type of trapezoidal screw that adheres to standardized specifications in the United States and the United Kingdom.

Key characteristics of ACME screws include a trapezoidal thread profile with a thread angle of 29 degrees and the use of inch measurements (fractions) to denote the screw’s outer diameter. The pitch of the screw is determined by the number of threads per inch. ACME screws come in two main variations: external threads (male threads) with helical threads on their outer cylindrical surface and internal threads (female threads) with helical threads on the inner surface of a hole.

One notable advantage of ACME screws is their cost-effectiveness, as they do not require balls, making production relatively inexpensive. Additionally, they are resistant to self-loosening due to their trapezoidal profile. ACME screws with low leads are particularly suited for applications such as valve control.

Wireless Gateway

What Is a Wireless Gateway?

A wireless gateway is a device designed to bridge wired and wireless networks.

Its primary purpose is to facilitate connections between devices that require either wired or wireless access to a network. These gateways are commonly used in corporate, residential, and public settings. Key components of a wireless gateway include wireless LAN modules, wired LAN modules, and a processing unit responsible for mediating and managing network communications.

The wireless gateway operates in two key roles: mediating communication between wireless and wired networks, enabling data transfer, and managing network connections. It performs protocol conversion and handles authentication processes to ensure secure and reliable connections between the two types of networks.

Turbine Flow Meter

What Is a Turbine Flow Meter?

A turbine flow meter is an instrument used to measure the flow rate of a fluid by detecting the rotation of a turbine rotor within the flow.

This device’s operating principle is based on the rotation of the turbine rotor, which is directly proportional to the fluid’s flow rate, enabling precise measurements. Turbine flow meters are extensively used in various industrial settings, including the measurement of water, gas, and steam flows. They are also crucial in energy sectors for monitoring the flow of crude oil and natural gas, and in environmental contexts for measuring sewage and wastewater flow rates.

Notable features of a turbine flow meter include high-precision measurement capabilities and the ability to measure instantaneous flow rates by responding quickly to changes in fluid flow. They are adaptable to a broad range of measurement needs, with adjustments in turbine rotor size and speed. Proper usage requires ensuring the fluid is free of solid particles and maintaining stable temperature and pressure conditions, as well as ensuring an adequate length of straight piping for accurate measurement.

Tube Expander

What Is a Tube Expander?

A tube expander is a tool used in various mechanical applications to increase the diameter of a tube.

This device operates mainly on two principles: expansion using a die and expansion using an expander. It is essential in fields such as piping, mechanical component fabrication, and construction, where it allows for the precise and efficient expansion of different types of tubes.

Typical applications include creating pipe connections, manufacturing mechanical parts, and reinforcing joints in building structures. Tube expanders come in three primary types: die-based, expander-based, and hybrid. Die-based expanders, known for their precision, are suitable for specific applications but can risk tube damage depending on the tube’s material and thickness. Expander-based expanders are safer and less labor-intensive, suitable for a wider range of applications. Hybrid expanders combine the advantages of both die and expander methods, offering versatility and efficiency.
