浮体

A float body is a buoyant component in float assemblies that regulates fluid levels through displacement.

技术定义与适配语境
典型 浮体 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The float body is a precisely engineered buoyant element within float assemblies, designed to displace fluid and actuate mechanical or electrical switches based on liquid level changes. It operates on Archimedes' principle, where buoyant force equals the weight of displaced fluid, enabling accurate level detection and control in tanks, reservoirs, and processing vessels.

定义
The float body is a precisely engineered buoyant element within float assemblies, designed to displace fluid and actuate mechanical or electrical switches based on liquid level changes. It operates on Archimedes' principle, where buoyant force equals the weight of displaced fluid, enabling accurate level detection and control in tanks, reservoirs, and processing vessels.
工作原理
Operates on buoyancy and displacement principles. As fluid level rises, the float body displaces more fluid, generating upward buoyant force that moves the assembly to trigger level sensors, switches, or valves. The specific gravity and volume determine its sensitivity and response characteristics.
材料
Typically made from corrosion-resistant materials: stainless steel (AISI 304/316)polypropylenePVCor fluoropolymers like PTFE for chemical resistance. Hollow construction with sealed welds or molded seams to prevent fluid ingress.
Diameter
50-300 mm
Buoyancy Force
0.5-10 N
Pressure Rating
Up to 10 bar
Specific Gravity
0.3-0.9
Operating Temperature
-20°C to 120°C
标准
ISO 2852DIN 11851

常见问题

How does material selection affect float body performance?

Material determines corrosion resistance, buoyancy, and temperature tolerance. Stainless steel offers durability in harsh environments, while polymers provide chemical resistance and lighter weight.

What maintenance does a float body require?

Regular inspection for cracks, corrosion, or seal degradation. Cleaning to prevent fouling that alters buoyancy. Calibration checks if used with precision level sensors.
