OPG-G1/2-100X40MPa-GR15日本ASK充油壓力表壓鑄機用，在壓鑄機的運行與控制中，壓力表的選擇需結合其核心工作環節（如鎖模、壓射、保壓、液壓系統）的壓力特性、精度需求及工況環境，不存在單一通用型壓力表，而是需根據具體功能模塊匹配專用類型。壓鑄機在工作時會產生強烈的振動和壓力脈動，因此需要使用耐震壓力表來準確測量壓力。

以下是關于壓鑄機用耐震壓力表的相關介紹：

工作原理

耐震壓力表在普通壓力表的基礎上，內部填充阻尼液（一般為硅油或甘油）并加裝緩沖機構。阻尼液能夠吸收機械振動能量，減少介質壓力的脈動影響，使指針的擺動得到緩沖，從而實現穩定清晰的讀數。

特點

抗震動耐沖擊：通過填充阻尼液和加固結構設計，如采用防震材料制作表殼、機芯等，可有效減少振動對儀表的影響，避免指針抖動、讀數不準甚至機芯損壞等問題，適用于壓鑄機這種高振動環境。
讀數穩定精準：阻尼液的緩沖作用使指針緩慢移動，能避免瞬時壓力波動導致的誤判，可準確測量壓鑄機工作時的壓力平均值，保證讀數的準確性。
使用壽命長：由于減少了振動對齒輪、游絲等部件的磨損，耐震壓力表的使用壽命相比普通壓力表可提升 2 至 3 倍，降低了維護成本和更換頻率。
防護性能好：部分耐震壓力表采用優質不銹鋼加厚外殼，防護等級可達 IP65，能有效防止灰塵、水等進入表內，保護內部機件。

選型要點

阻尼液選擇：甘油為通用型，適用于 - 10℃至 60℃的溫度范圍，成本較低，但低溫易凝固；硅油的耐溫范圍廣，為 - 40℃至 200℃，適合高溫或極寒環境的壓鑄機使用。
量程與精度：量程一般建議覆蓋工作壓力的 1.5 倍，例如壓鑄機的工作壓力為 10MPa，則應選擇量程為 0 至 16MPa 的壓力表。精度方面，普通工況可選擇 1.6 級精度的壓力表，對于精度要求較高的壓鑄工藝，可選擇 0.4 級精度的產品，但通常需要定制。
接口與材質：接口要與壓鑄機的壓力測量點相匹配，常見的有 G1/2、M20×1.5 等。殼體材質方面，普通環境可選用碳鋼材質，若壓鑄機工作環境存在腐蝕性介質，則應選擇 304 或 316 不銹鋼材質。

常見型號

市場上常見的耐震壓力表型號有 YN 系列，如 YN-40、YN-50、YN-63、YN-100、YN-150 等。精度等級為 ±1.6% F.S，壓力表面徑分別為 40mm、50mm、63mm、100mm、150mm，可根據實際需求選擇不同的型號。

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.
