详细介绍

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:

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.

四、使用时应注意事项:

1、安装齿轮油泵:

a. 安装前应检查泵在运输中是否受到损坏,如电机是否受潮、泵进出口的防尘盖是否损坏而使污物进入泵腔内部等。

b. 安装管道前应先对管道内壁用清水或蒸气清洗干净。安装时应避免使管道的重量由泵来承担,以免影响泵的精度及寿命。

c. 齿轮油泵应尽量靠近油池;管道各联接部位不得漏气、漏液,否则会发生吸不上液体的现象。

d. 为防止颗粒杂盾等污物进入泵内,应在吸入口安装金属过滤网,过滤精度为30目/in,过滤面积应大于进油管横截面积三倍以上。

e. 进出口管路建议安装真空表及压力表,以便监视泵的工作状态。

f. 当油池较深、吸油管路较长或介质粘度较高而造成真空度过高时,可将进油管加粗一挡。吸油管路较长时还应安装底阀。

2、齿轮油泵工作前的检查:

a. 泵的各紧固件是否牢固。

b. 主动轴转动是否轻重均匀一致。

c. 进出管道的阀门是否打开。

d. 泵的旋转方向是否符合要求。

e. 初次使用前应向泵内注入适量介质。

3、齿轮油泵工作时的维护:

a. 注意齿轮油泵的压力表及真空表的读数应符合该泵所规定的技术规范以内。

b. 当齿轮油泵在运转中有不正常的噪音或温升过高时,应立即停泵检查。

c. 一般情况下,不得任意调整安全阀,如需调整时,要用仪器校正。

d. 额定压力的1.5-2倍。4、泵的停止

a. 切断电源。

b. 关闭进出管道阀门。

    KCB133-960、2CY8-60齿轮式输油泵有采用DU轴承,锡青铜轴承和滚动轴承三种结构,需在订货时注明。订货时未注明者均按DU轴承结构供货。

    轴承为内置型式,依靠被输送介质进行润滑;011轴承和锡青铜轴承能在非润滑性介质中工作。


4. Precautions for installing gear oil pump:


a. Before installation, check whether the pump has been damaged during transportation, such as whether the motor is damp, whether the dust cover of the inlet and outlet of the pump is damaged and the dirt enters the pump cavity, etc.


b. Before installing the pipeline, clean the inner wall of the pipeline with clean water or steam. During installation, avoid letting the weight of the pipeline be borne by the pump to avoid affecting the accuracy and service life of the pump.


c. The gear oil pump should be placed as close to the oil tank as possible; all joints of the pipeline should not leak air or liquid, otherwise, the phenomenon of unable to suck liquid will occur.


d. In order to prevent impurities such as particles and debris from entering the pump, a metal filter screen with a filtration accuracy of 30 mesh/in should be installed at the suction port, and the filtration area should be more than three times the cross-sectional area of the inlet pipe.


e. It is recommended to install a vacuum gauge and a pressure gauge on the inlet and outlet pipelines to monitor the working status of the pump.


f. When the oil tank is deep, the suction pipe is long, or the viscosity of the medium is high, causing the vacuum degree to be too high, the inlet pipe can be thickened by one level. When the suction pipe is long, a bottom valve should also be installed.


5. Inspection before gear oil pump operation:


a. Whether all fasteners of the pump are firm.


b. Whether the rotation of the drive shaft is light and uniform.


c. Whether the valves of the inlet and outlet pipelines are open.


d. Whether the rotation direction of the pump meets the requirements.


e. Before first use, inject an appropriate amount of medium into the pump.


6. Maintenance during gear oil pump operation:


a. Pay attention to whether the pressure gauge and vacuum gauge of the gear oil pump meet the technical specifications specified by the pump.


b. When abnormal noise or excessive temperature rise occurs during the operation of the gear oil pump, stop the pump immediately for inspection.


c. In general, do not adjust the safety valve arbitrarily. If adjustment is necessary, use an instrument for calibration.


d. 1.5-2 times of rated pressure.

7. Pump stop:


a. Cut off power supply.


b. Close inlet and outlet pipeline valves.


KCB133-960 and 2CY8-60 gear oil pumps have three types of structures: DU bearings, tin bronze bearings, and rolling bearings. Please specify when ordering. If not specified when ordering, DU bearing structure will be supplied by default.


The bearing is an embedded type, relying on the conveyed medium for lubrication; 011 bearings and tin bronze bearings can work in non-lubricating media
