美国Gates GT齿型同步带保力强碳纤维皮带
U.S. Gates Synchronization Belt Preserving Strength Carbon Fiber Belt
Gates同步带的耐油性：
—Oil Resistance of Gates Powerful Belt
在传动过程中的油脂飞溅到皮带表面并不影响皮带的正常运转和使用。然而，当碰到适量的油时，耐***带不会很快失效。反而大量的油脂会导致同步带齿面与带轮齿面打滑的情况，可能会造成同步带跳齿。如果较为广泛的接触成品油可能会导致橡胶材质膨胀，皮带粘结部分裂开。
——The splashing of grease on the surface of the belt during tran***ission does not affect the normal operation and use of the belt. However, when a suitable amount of oil is encountered, the oil-resistant belt will not quickly fail. On the contrary, a large amount of grease will lead to the slippage of synchronous belt tooth surface and pulley tooth surface, which may cause synchronous belt skipping. Extensive contact with the finished oil may cause the rubber material to expand and the adhesive part of the belt to crack.
Gates同步带的耐臭氧：
—Ozone Resistance of Gates Powerful Belt
当Gates皮带暴露在臭氧环境中，臭氧会导致化学键分开，皮带***是其典型的失效模式。降解程度是由臭氧浓度和接触频率决定。皮带弯曲应力同样增加了臭氧降解。因此，当绕在直径相同的带轮上，横截面大的皮带理论上降解程度大于横截面小的皮带。
——When Gates belt is exposed to ozone, ozone will lead to the separation of chemical bonds, and belt rupture is a typical failure mode. Degradation is determined by ozone concentration and contact frequency. The bending stress of belt also increases ozone degradation. Therefore, when the belt is wound around the same diameter pulley, the degradation degree of the belt with large cross-section is theoretically greater than that of the belt with ***all cross-section.
Gates同步带的阻燃性：
—Flame Retardant of Gates Powerful Belt
美国盖茨皮带在一定程度上附有可以压制或者不传播火焰的能力，当直接暴露在火焰中。有许多矿业标准以及***实验室水平和垂直燃烧测试程序准则。联系产品应用工程师获取更多信息。
——The Gates Belt in the United States has the ability to suppress or not propagate flame to a certain extent when exposed directly to the flame. There are many mining standa*** and insurance laboratory standa*** for horizontal and vertical combustion testing procedures. Contact the Product Application Engineer for more information
日本KITZ北泽调节阀门
KITZ Kitazawa Regulating Valve in Japan
北泽kitz调节阀的组成结构：
—Kitazawa Kitz control valve structure:
1、主要是油电动执行机构或气动执行机构和调节阀两部分组成。
2、调节并通常分为直通单座式和直通双座式两种，后者具有流通能力大、不平衡办小和操作稳定的特点，所以通常特别适用于大流量、高压降和泄漏少的场合。
—— Regulation is usually divided into two types: through single seat type and through double seat type. The latter has the characteristics of large circulation capacity, ***all unbalanced operation and stable operation, so it is usually especially suitable for large flow, high pressure drop and less leakage occasi***.
3、流通能力Cv是选择调节阀的主要参数之一，调节阀的流通能力的定义为：当调节阀全开时，阀两端压差为0.1MPa，流体密度为1g/cm3时，每小时流径调节阀的流量数，称为流通能力，也称流量系数，以Cv表示，单位为t/h
——Flow capacity Cv is one of the main parameters for choosing control valve. Flow capacity of control valve is defined as: when the control valve is fully open, the pressure difference at both ends of the valve is 0.1 MPa, and the fluid density is 1 g/cm3, the flow number of flow rate per hour of flow regulating valve is called flow capacity, also known as flow coefficient, expressed in Cv and expressed in t/h units.
