Lubrication Pressure Gauge

The Liquid-Filled Shockproof Lubrication System Pressure Gauge provides operators with a direct, visual confirmation of system performance. While electronic switches provide digital alerts, a physical gauge allows maintenance personnel to diagnose pressure fluctuations, observe pressure-relief cycles, and verify pump health at a glance. Filled with vibration-dampening glycerin or silicone oil, the needle remains stable even on the most aggressively vibrating heavy machinery.

Key Advantages & Benefits:

  • Vibration Resistance: The liquid fill absorbs machine vibrations and pulsations, preventing needle flutter and extending gauge life.
  • Clear Visibility: High-contrast dials and anti-fogging glass ensure easy reading in all industrial conditions.
  • Corrosion Protection: Stainless steel casing and brass internals resist rust and degradation.
  • Precise Diagnostics: Allows technicians to spot slow pressure drops indicating minor leaks before they become major failures.

Versatile Applications:

  • Pump output verification
  • Dual-line distributor monitoring
  • Hydraulic pressing machines
  • Stamping and forging equipment

Frequently Asked Questions (FAQ):

  • Q: Why is there an air bubble inside the gauge? A: A small air bubble at the top of a liquid-filled gauge is completely normal and necessary. It allows the liquid to expand and contract with temperature changes without breaking the glass.
  • Q: What pressure range should I choose? A: You should select a gauge where your normal operating pressure falls roughly in the middle of the dial (e.g., use a 0-200 bar gauge for a 100 bar system).

FAQ

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation


Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.


Process Validation Before Mass Manufacturing


Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.


Integrated Heating and Degassing Process


The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
