产品概述:
KCB系列齿轮泵KCB SERIES GEAR PUMP
一、产品介绍:
KCB齿轮泵适用于输送各种油类、如重油、柴油、润滑油,配用铜齿轮可输送内点低液体,如气油、笨等所以称为齿轮油泵,不锈钢齿轮泵可输送饮料和腐蚀性的液体。不适用于含硬质颗粒或纤维的,适用粘度为5×10-5~1.5×103m2/s。温度不高为70℃,如需输送高温液体,单级单吸油泵请使用耐高温齿轮油泵,可输送300℃以下液体。
二、KCB齿轮油泵特点:
1、 该电动抽油泵结构简单紧凑,使用和保养方便。
2、 具良好的自吸性,故每次开泵前不须灌入液体。
3、 润滑是靠输送的液体而自动达到的,故日常工作时无须另加润滑液。
4、利用弹性联轴器传递动力可以补偿因安装时所引起的微小偏差。在油泵工作中受到不可避免的液压冲击时,能起到良好的缓冲作用。
三、结构说明:
KCB齿轮油泵泵体、齿轮、前后泵盖、安全阀、轴承及密封装置等零、部件组成.
1、泵体、前后盖等零件为灰铸铁件,齿轮用优质碳素钢制作;亦可根据用户需要用铜材或不锈钢制作。
2、安全阀。KCB系列油泵在后泵盖或泵体上方装有安全阀,齿轮油泵 当泵或排出管道发生故障或将排出阀门关闭而产生高压和高压沖击时安全阀就会自动打开,卸除部分或全部的高压液体回到吸入腔,从而对泵及管道起到安全保护作用。
3、轴承。2CY系列油泵采用DU轴承;可根据用户要求采用锡青铜轴承。&0818.3-83.3、2CY1.1齿轮油泵采用DU轴承;可根据用户要求采用锡青铜轴承。
4、轴封。本系列齿轮油泵产品的轴端密封有骨架油封、机械密封及填料密封三种结构。
a. 骨架油封:骨架油封的特点是维护、更换方便,成本低,但寿命较短。丁晴胶骨架油封适用于1001:以下工作环境;氟橡胶骨架油封适用于200℃以下工作环境。
b. 1机械密封:机械密封的特点是密封可靠、寿命长,成本高。机械密封的基体用不锈钢制造, 动、静环视介质不同分别由YG8硬质合金或YG8-石墨制造,使用温度在200℃以下。
c. 填料密封:填料密封仅用于高温油泵,其特点是耐高温,有少量泄漏。使用过程中需根据泄漏情况经常进行调整,使用温度在250℃:以下。
用户需何种型式的密封结构需在订货时注明。凡订货时未注明者均按丁晴胶骨架油封或填料结构供货。
5、进、出油口型式:
2CY系列齿轮油泵进、出油口为与口径对应的英制管螺纹(G),直接制作在泵体上。
KCB18.3-200、2CY1.1-12齿轮式输油泵配带管螺紋口的腰形法兰;其余泵不配带法兰,当用户需要配带法兰时,应在订货中注明。
6、泵与电机用弹性联轴器连接,并安装在公共底盘上。
Product Introduction:
The KCB gear pump is suitable for conveying various oils, such as heavy oil, diesel, and lubricating oil. Copper gears can be used to transport low-viscosity liquids such as gas and benzene, which is why it is called a gear oil pump. Stainless steel gear pumps can transport beverages and corrosive liquids. It is not suitable for liquids containing hard particles or fibers and is suitable for viscosities ranging from 5×10-5 to 1.5×103m2/s. The temperature should not exceed 70℃. For high-temperature liquids, a high-temperature-resistant gear pump should be used, which can transport liquids below 300℃.
Features of KCB Gear Pump:
The electric oil pump has a simple and compact structure, making it easy to use and maintain.
It has good self-priming ability, so there is no need to fill liquid before each pump start.
Lubrication is automatically achieved by the conveyed liquid, so there is no need to add lubricating oil during daily operation.
Power transmission through an elastic coupling can compensate for small deviations caused by installation. It can provide a good cushioning effect when subjected to unavoidable hydraulic shocks during oil pump operation.
Structure Description:
The KCB gear pump consists of a pump body, gears, front and rear pump covers, safety valve, bearings, and sealing device. The pump body, front and rear covers, and other parts are made of gray cast iron, and the gears are made of high-quality carbon steel. Copper or stainless steel can also be used according to user needs. The safety valve is installed on the rear pump cover or above the pump body to provide safety protection for the pump and pipeline. The bearings use DU bearings or tin bronze bearings, and the shaft end seal has three structures to choose from: skeleton oil seal, mechanical seal, and packing seal. The inlet and outlet ports are made with British pipe threads (G) directly on the pump body. The pump is connected to the motor with an elastic coupling and installed on a common base.
