9907-1200  WOODWARD 电流压力转换器 提高负载空制

型号：9907-1200

品牌：WOODWARD

WOODWARD 9907-1200需要安装在适配器块(或板)上。适配器块将CPC-上的三个液压端口与外部供油、液压排放和阀伺服控制装置连接。

WOODWARD 9907-1200通过四个M10x1.5螺钉连接(夹紧）在适配器块上。螺钉应与CPC-lII的螺纹啮合至少16 mm，以实现可靠和牢固的安装。接口应设计有沉孔，以接受面密封O型圈。该板可以使用两个M12或更大的螺钉连接到支撑结构，或者歧管可以焊接到位。

WOODWARD 9907-1200可以安装在任何姿态。然而，对于涉及油污染或夹带水的应用，建议的方向是流体端口朝下。留出空间，以便卸下顶盖、接近接线板以及查看印刷电路板上的状态指示灯。将CPC-II靠着适配器板放置。确保O型环就位，并用M10x1.5螺钉将CPC-lI固定到歧管上，并将其扭转至适合紧固件拉伸载荷的水平(拉伸区域屈服强度为667MPa的合金钢内六角螺钉的典型60-80 N-m)。

确保液压端口正确连接到系统:S连接到液压供应，C连接到伺服控制压力，T连接到液压排放。

Model: 9907-1200

Brand: WOODWARD

The WOODWARD 9907-1200 needs to be mounted on an adapter block (or board). The adapter block connects three hydraulic ports on the CPC- to the external oil supply, hydraulic discharge, and valve servo controls.

The WOODWARD 9907-1200 is attached (clamped) to the adapter block via four M10x1.5 screws. The screw should be engaged with the threads of the CPC-lII at least 16 mm for a reliable and firm installation. The interface shall be designed with countersunk holes to seal the O-ring at the receiving surface. The plate can be attached to the support structure using two M12 or larger screws, or the manifold can be soldered in place.

The WOODWARD 9907-1200 can be mounted in any position. However, for applications involving oil contamination or entrainment of water, the recommended direction is fluid port down. Leave room to remove the top cover, access the patch board, and view the status indicator on the printed circuit board. Place the CPC-II against the adapter board. Make sure the O-ring is in place and secure the CPC-lI to the manifold with M10x1.5 screws and twist it to a level suitable for the tensile load of the fastener (typical 60-80 N-m for alloy steel hex head screws with a yield strength of 667MPa in the tensile area).

Make sure the hydraulic ports are properly connected to the system :S is connected to the hydraulic supply, C is connected to the servo control pressure, and T is connected to the hydraulic discharge.

WOODWARD 9907-1200 Features and functions

Woodward's second generation Current Pressure Converter (CPCI) 10 bar, 2-zone, simplex version with enhanced dynamic performance is an electro-hydraulic pressure regulation control valve for positioning the f actuator of a single acting steam turbine valve server. CPClI addresses one of the industry's number one reliability issues affecting equipment uptime and performance.

The CPC-I accepts pressure demand signals from 4 to 20 mA and precisely controls the oil pressure to precisely position the single-acting turbine speed-regulating valve. Accurate and stable steam valve control is directly related to the improvement of steam turbine speed and load air conditioning, and the reduction of mechanical wear of the system.
