OPG-G1/2-100X40MPa-GR15日本ASK充油压力表压铸机用，在压铸机的运行与控制中，压力表的选择需结合其核心工作环节（如锁模、压射、保压、液压系统）的压力特性、精度需求及工况环境，不存在单一通用型压力表，而是需根据具体功能模块匹配专用类型。压铸机在工作时会产生强烈的振动和压力脉动，因此需要使用耐震压力表来准确测量压力。


以下是关于压铸机用耐震压力表的相关介绍：

工作原理

耐震压力表在普通压力表的基础上，内部填充阻尼液（一般为硅油或甘油）并加装缓冲机构。阻尼液能够吸收机械振动能量，减少介质压力的脉动影响，使指针的摆动得到缓冲，从而实现稳定清晰的读数。

特点

  • 抗震动耐冲击：通过填充阻尼液和加固结构设计，如采用防震材料制作表壳、机芯等，可有效减少振动对仪表的影响，避免指针抖动、读数不准甚至机芯损坏等问题，适用于压铸机这种高振动环境。

  • 读数稳定精准：阻尼液的缓冲作用使指针缓慢移动，能避免瞬时压力波动导致的误判，可准确测量压铸机工作时的压力平均值，保证读数的准确性。

  • 使用寿命长：由于减少了振动对齿轮、游丝等部件的磨损，耐震压力表的使用寿命相比普通压力表可提升 2 至 3 倍，降低了维护成本和更换频率。

  • 防护性能好：部分耐震压力表采用优质不锈钢加厚外壳，防护等级可达 IP65，能有效防止灰尘、水等进入表内，保护内部机件。

选型要点

  • 阻尼液选择：甘油为通用型，适用于 - 10℃至 60℃的温度范围，成本较低，但低温易凝固；硅油的耐温范围广，为 - 40℃至 200℃，适合高温或极寒环境的压铸机使用。

  • 量程与精度：量程一般建议覆盖工作压力的 1.5 倍，例如压铸机的工作压力为 10MPa，则应选择量程为 0 至 16MPa 的压力表。精度方面，普通工况可选择 1.6 级精度的压力表，对于精度要求较高的压铸工艺，可选择 0.4 级精度的产品，但通常需要定制。

  • 接口与材质：接口要与压铸机的压力测量点相匹配，常见的有 G1/2、M20×1.5 等。壳体材质方面，普通环境可选用碳钢材质，若压铸机工作环境存在腐蚀性介质，则应选择 304 或 316 不锈钢材质。

常见型号

市场上常见的耐震压力表型号有 YN 系列，如 YN-40、YN-50、YN-63、YN-100、YN-150 等。精度等级为 ±1.6% F.S，压力表面径分别为 40mm、50mm、63mm、100mm、150mm，可根据实际需求选择不同的型号。

ASK Oil-Filled Pressure Gauge (Made in Japan) for Die-Casting Machines

In the operation and control of die-casting machines, the selection of pressure gauges must be based on the pressure characteristics, accuracy requirements and working conditions of core processes such as mold clamping, injection, pressure holding and the hydraulic system. There is no single universal pressure gauge; instead, a dedicated type must be matched to specific functional modules. Die-casting machines generate strong vibration and pressure pulsation during operation, so vibration-resistant pressure gauges are required for accurate pressure measurement.

Introduction to Vibration-Resistant Pressure Gauges for Die-Casting Machines

Working Principle

Based on a standard pressure gauge, the vibration-resistant type is filled with damping fluid (usually silicone oil or glycerin) and equipped with a buffer mechanism. The damping fluid absorbs mechanical vibration energy, reduces the influence of medium pressure pulsation, and dampens pointer oscillation, ensuring stable and clear readings.

Features

  • Anti-vibration & shock resistance: With damping fluid filling and reinforced structural design (including shock-resistant case and movement), it effectively reduces the impact of vibration, preventing pointer fluttering, inaccurate readings and movement damage, making it ideal for high-vibration environments such as die-casting machines.

  • Stable & accurate readings: The damping effect of the fluid ensures smooth pointer movement, avoiding misjudgment caused by instantaneous pressure fluctuations. It accurately measures the average working pressure of die-casting machines for reliable readings.

  • Long service life: By reducing wear on gears, hairsprings and other components, the service life is 2 to 3 times longer than that of standard pressure gauges, lowering maintenance costs and replacement frequency.

  • Excellent protection: Some models feature a heavy-duty high-quality stainless steel case with protection class up to IP65, effectively blocking dust and water ingress to protect internal parts.

Selection Criteria

  • Damping fluid selection:

    Glycerin is a general-purpose option, suitable for temperatures from -10℃ to 60℃ with low cost, but tends to solidify at low temperatures.

    Silicone oil offers a wide temperature range of -40℃ to 200℃, ideal for die-casting machines operating in high-temperature or extremely cold environments.

  • Range & accuracy:

    The measuring range is recommended to be 1.5 times the working pressure. For example, if the working pressure is 10 MPa, a gauge with a range of 0 to 16 MPa should be selected.

    For general working conditions, Class 1.6 accuracy is sufficient; for high-precision die-casting processes, Class 0.4 accuracy is available, usually on a custom basis.

  • Connection & material:

    Connections must match the pressure measurement ports of the die-casting machine; common types include G1/2, M20×1.5, etc.

    Carbon steel is suitable for general environments; for corrosive working conditions, 304 or 316 stainless steel is recommended.

Common Models

Common vibration-resistant pressure gauges on the market include the YN series: YN-40, YN-50, YN-63, YN-100, YN-150, etc. They feature an accuracy class of ±1.6% F.S. and dial diameters of 40mm, 50mm, 63mm, 100mm and 150mm, allowing selection based on actual requirements.
