German ebara pumps tools, ebara pumps models, ebara pumps prices

ebara pumps tools refer to electrical safety tools, which are various specialized tools and devices designed to prevent accidents such as electric shock, burns, falls, and slips, thereby ensuring the personal safety of workers. In power systems, operators must carry and use various safety tools to complete tasks smoothly without causing personal injury. For example, electrical safety tools are required when inspecting operating electrical equipment, changing operating modes, or performing maintenance and tests; climbing safety tools are needed during line construction; when working on live electrical equipment or in areas near live equipment, insulated safety tools must be used to prevent electric shock or arc burns. Electrical safety tools can be divided into four categories: personal protective equipment, insulated safety tools, climbing tools, and warning signs.

ebara pumps tool classification

1) Tools: Magnetic properties of materials are often utilized in production to facilitate operations, such as using magnetic screwdrivers during electronic product assembly. In machining, a large amount of fine iron chips is generated. These chips flow back with the cooling medium into the recovery container, often causing circuit blockages and making cleaning inconvenient. A magnetic oil trough can be installed on the machine tool. During metal cutting, the cooling medium containing iron chips flows from the worktable drain into the oil trough. As it passes through the filter screen, the iron chips are blocked and accumulate on one side due to the action of ring magnets, while the cooling medium flows into the oil tank through the oil channel. Cleaning is very convenient: simply lift the oil trough and dump the chips. 2) Molds: When bending and forming workpieces with complex shapes, eccentricity of the center of gravity may occur. If the mold is too small, it may create a cantilever effect, causing unstable placement of the workpiece and leading to flipping or warping. For example, a positioning magnet can be added to the die cavity to assist in workpiece positioning, which reduces the mold volume and increases positioning reliability. 3) Auxiliary tools: In stamping production, steel plates stacked for processing have no gaps between them and stick together due to atmospheric pressure and other factors, making material handling extremely inconvenient. This problem can be solved by installing a magnetic auxiliary workbench close to the press. The working principle is as follows: a baffle is fixed on the workbench, with a magnet installed on one side. The plates to be processed are placed against the other side of the baffle. During operation, the up-and-down movement of the press slider and vibrations caused by the punching force cause the plates to vibrate vertically. The top plate, unable to overcome the magnetic force due to insufficient gravity, leans against the baffle, naturally creating a gap for easy material handling. The magnetic force can be adjusted by changing the thickness of the baffle. Magnetic force acts like an invisible hand to hold the workpiece. By cleverly utilizing magnet technology, we simplify the structure of various tools, improve the process performance of workpieces, and make production easier. Thus, magnetic tools can help achieve unexpected results.

ebara pumps tool structure and composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces, while transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed on the chuck surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces with the same contact area; the point of application of magnetic force is limited to the contact surface between the workpiece and the chuck and cannot be freely changed. Therefore, machining with standard electromagnetic chucks has disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

ebara pumps tool features

Electrically controlled powerful chucks offer superior holding force, reaching up to 16kg/cm², with uniform and adjustable magnetic distribution, making them suitable for various heavy-duty machining, roughing, and finishing operations. Standard powerful chucks have weaker and uneven holding force, unable to meet the requirements of heavy-duty machining. The holding force of electrically controlled powerful chucks does not require a continuous power supply to maintain, generating no heat during continuous operation, thus avoiding thermal deformation of workpieces. Meanwhile, the strong and uniform surface suction ensures the highest machining precision even if the workpiece overhangs the table. In contrast, standard electromagnetic chucks require a continuous current supply, generating heat after a period of operation. This not only causes thermal deformation of the workpiece but also reduces the chuck's magnetic force, failing to guarantee machining precision. Electrically controlled powerful chucks can be used continuously; even with daily continuous operation for more than 20 hours, no faults will occur, and no maintenance is required. Standard permanent magnet chucks typically experience a decline in holding force after about half a year of use, while electromagnetic chucks can only operate for a few hours each day and are prone to failures, requiring frequent replacement and repair of internal components. Using standard powerful chucks requires significant time for workpiece adjustment, accounting for 40%-50% of the entire machining process, and clamping positioning is prone to obvious errors, resulting in high scrap rates and very low efficiency. Electrically controlled powerful chucks feature automatic auxiliary positioning; simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.
