液下渣浆泵在使用的时候应该注意什么

作者:小编 时间:2021-05-27 16:24:59 点击:

液下渣浆泵为单级、单吸悬臂式结构,用轴承座,支承板,联接管连接泵的水力部件,液体由出液管部件排出,泵的叶轮为半开式叶轮,在叶轮叶片进口延伸处设有搅拌叶片,该泵主要特点是在液下部位的泵轴,有足够的刚度,叶轮,泵壳之间不设轴承,不采用轴封,可以输送含有较大浓度固定颗粒的介质。

The submerged slurry pump is a single-stage, single suction cantilever structure. The hydraulic components of the pump are connected by bearing seat, support plate and connecting pipe. The liquid is discharged from the liquid outlet pipe. The impeller of the pump is a semi open impeller, and the mixing blade is set at the inlet extension of the impeller blade. The main characteristics of the pump are that the pump shaft in the submerged part has enough rigidity, and there is no bearing between the impeller and the pump shell, Without shaft seal, it can transport media with large concentration of fixed particles.

    泵插入液下的长度在800-3000之间,如果需要可以配带吸入管。传动由立式电动机安装在电机座和支承座上,用联轴器与泵相连。液下渣浆泵也是离心泵中的一种,为了满足生产上的需求,将它设计成为单级单吸悬臂式的结构。它工作效率高,输送效果好。下面淄博孝昌机械制造有限公司就为大家介绍一下液下渣浆泵使用过程中的注意事项。首先,在液下渣浆泵启动和停止时,要注意观察泵的安装基础是否稳固,比如螺栓等。要检查泵轴向间隙是否已经调整好,以及电机的选择方向是否正确。

The length of the pump inserted into the liquid is between 800-3000. If necessary, it can be equipped with a suction pipe. The drive is installed on the motor base and support base by vertical motor, and connected with the pump by coupling. Submerged slurry pump is also a kind of centrifugal pump. In order to meet the needs of production, it is designed as a single-stage single suction cantilever structure. It has high working efficiency and good conveying effect. The following Zibo Xiaochang Machinery Manufacturing Co., Ltd. will introduce the matters needing attention in the use of submerged slurry pump. First of all, when starting and stopping the submerged slurry pump, pay attention to observe whether the installation foundation of the pump is stable, such as bolts, etc. Check whether the axial clearance of the pump has been adjusted, and whether the selection direction of the motor is correct.

    在启动电机时,要打开压力表旋塞,当泵以全转数工作时,调节闸阀开度到需要范围。泵停止工作时,应先停止电动机,然后闭上压力表旋塞。如果泵长期停止运行时,应将泵拆开,擦拭干净,涂上防锈油妥善保存。在液下渣浆泵运转的时候,注意泵轴承温度,不应超过外界温度35度但最高不应大于75度。油杯内应注满钙基黄油,保证轴承能正常润滑。泵在工作第一个月内,或运转100小时后,应更换电机支承油杯内的黄油,以后每工作2000小时后更换一次。定期检查弹性联轴器,注意电机轴承温升。

When starting the motor, open the cock of the pressure gauge. When the pump is working at full speed, adjust the opening of the gate valve to the required range. When the pump stops working, stop the motor first, and then close the pressure gauge cock. If the pump stops running for a long time, the pump should be disassembled, wiped clean, coated with anti rust oil and properly stored. When the submerged slurry pump is running, pay attention to the temperature of the pump bearing, which should not exceed the external temperature of 35 degrees, but the maximum temperature should not exceed 75 degrees. The oil cup shall be filled with calcium base grease to ensure normal lubrication of the bearing. The grease in the motor support oil cup should be replaced within the first month of operation or after 100 hours of operation, and then every 2000 hours of operation. Check the elastic coupling regularly and pay attention to the temperature rise of motor bearing.
