进口液下泵/Submerged pump/德国品质
德国KAYSEN凯森进口液下泵概述
液下泵是一种正压输送立式泵，可有效解决气阻、气蚀问题。输送物料的防爆等级决定了液下泵产品具有不同的结构、工作原理、分类、适用范围、产品优缺点和操作方式，可简单分为传统液下泵（罐外1区防爆、罐内0区不防爆）和新型液下泵（罐外1区防爆、罐内0区防爆）两大类。
主要特点：
●能够与 CPT ANSI B73.1 化工泵互换外壳和叶轮
●球墨铸铁或双相不锈钢外壳配合双相不锈钢叶轮，使用寿命长
●多种材料的重载荷轴承，可提升耐腐蚀性和高扭矩能力
●提供各种液位开关、液位传感器和其他仪器
主要应用：
广泛应用于油田、炼油、石油化工、化学制品、化肥、***、冶金、食品、纺织、医药和制冷等领域工业系统中,输送不含固体颗粒的******、******、腐蚀性介质及不允许密封污染的介质，不适宜输送含有铁磁性物质的介质。
液下泵故障处理及防范措施：
液下泵在使用过程中，往往会遇到一些故障，下面介绍几种常见故障，并提供处理方法及防范措施：
故障现象：
(1)液下泵运行正常不打水。

Germany KAYSEN imported submerged pump overview
The submerged pump is a positive pressure conveying vertical pump, which can effectively solve the problem of air resistance and c***itation. The explosion-proof grade of the transported material determines that the submerged pump product has different structure, working principle, classification, scope of application, product advantages and disadvantages, and operation mode. It can be easily divided into traditional submerged pump (explosion-proof zone 1 outside the tank, zone 0 in the tank) There is two categories of non-explosion-proof pumps and new submerged pumps (explosion-proof in Zone 1 outside the tank and explosion-proof in Zone 0 in tanks).
main feature:
● Ability to interchange housing and impeller with CPT ANSI B73.1 chemical pump
● Ductile iron or duplex stainless steel shell with duplex stainless steel impeller, long service life
● He***y-duty bearings of various materials for improved corrosion resistance and high torque capacity
●Provide various liquid level switches, liquid level sensors and other instruments
main application:
Widely used in industrial systems such as oilfield, oil refining, petrochemical, chemical, fertilizer, nuclear power, metallurgy, food, textile, medicine and refrigeration, conveying flammable, explosive, toxic, harmful and corrosive media without solid particles. It is not allowed to seal contaminated media, and it is not suitable to transport media containing ferromagnetic substances.
Submerged pump troubleshooting and precauti***:
When the submerged pump is in use, it often encounters some faults. The following describes several common faults, and provides treatment methods and preventive measures:
Fault phenomenon:
(1) The submerged pump operates normally without water.
(2) The submerged pump operates with abnormal sound.
Cause Analysis:
(1) There is debris in the suction port of the pump to block the normal operation of the submerged pump.
(2) After the pump is overhauled, the motor wiring is reversed.
(3) The pump bearing and bushing are seriously worn, causing displacement of the submerged pump impeller and friction with the pump casing.
Approach:
(1) Clean up the inlet debris of the submerged pump.
(2) Reconnect the power line phase by contacting the electric heater.
(3) Disassemble the submerged pump, replace the bearing and the bushing to ensure sufficient clearance between the pump impeller and the housing.
Precauti***:
(1) Strengthen the inspection and deal with problems in a timely manner.
(2) Improve the maintenance process training of employees and strictly control the quality.
