King Air LS-507 Overload Protector Pump is a specialized hydraulic pump used in the overload protection system of King Air mechanical stamping machines. The device is responsible for generating and maintaining oil pressure in the overload protection assembly, helping to detect overload conditions and cut off force transmission promptly, thereby protecting dies, crankshafts, connecting rods, and important machine parts from damage caused by pressing forces exceeding allowable limits.
King Air LS-507 Overload Protector Pump Specifications
- Model: LS-507
- Type: Overload Protector Pump
- Brand: King Air
- Application: Mechanical stamping machine overload protection systems
- Working Pressure: 315–400 kg/cm² (depending on version)
- Recommended Hydraulic Oil: ISO VG32 or equivalent
- Operating Noise Level: <76 dB
Product Highlights
- Ultra-fast trip response speed: When an overload occurs (e.g., jammed workpiece, out-of-spec workpiece thickness), the pump triggers the release of oil pressure in the stamping machine cylinder chamber within milliseconds, instantly stopping the slide stroke.
- High accuracy and reliability: The relief valve and pressure switch integrated into the LS-507 pump are made of special alloy steel, capable of withstanding high pressure and featuring extremely low activation error, ensuring the machine always stops at the exact hazardous moment.
- Integrated electronic limit switch: After hydraulic pressure release, the electronic system on the pump sends an emergency shutdown signal to the central control cabinet (PLC) of the stamping machine to completely lock machine operation, ensuring absolute safety for the operator.
- Automatic operation and easy recovery: After resolving the workpiece jam or overload issue, the operator simply activates the reset button on the electrical cabinet, and the pump automatically reloads oil pressure into the protection chamber so the machine is ready to operate again without mechanical disassembly.
Applications
The King Air LS-507 overload protector pump is used in:
- King Air mechanical stamping machines.
- Sheet metal stamping lines.
- Automotive and motorcycle component manufacturing industries.
- Electrical - electronics and metal processing industries.
- Household and industrial appliance manufacturing plants.
Usage Notes
- Precise pressure setting: The pump's load-release activation pressure must be adjusted to suit the technical specifications of each die set and the maximum stamping capacity of the machine. Do not set the pressure too high as it will negate the protective effect of the pump.
- Check hydraulic oil quality: The pump uses specialized hydraulic oil for transmission. Periodic checks are required for replacement if the oil is contaminated, contains metal sediment, or has degraded, preventing the internal pressure relief valve from jamming.
- Ensure pipeline system tightness: The oil pipelines from the pump to the protective cylinders must be securely fastened and leak-free. If the system experiences air ingress or oil pressure drop, the pump will issue an error signal and prevent the stamping machine from starting.
