Bearing: SKF chooses import bearings or NTN bearing. The reasonable bearing configuration, to prolong the service life of the pump. Cooling: Built-in cooling system, no matter in liquid surface or motor is in liquid surface, all can make pump working normally. Pumping the liquid from the body part of pump cycle to cooling tube and cabinet take the heat generated between motor. Need external cooling, cooling set can be separated, and with the pump body and individual cooling system connected. Motor: Motor for class F insulation, the highest working temperature of 155 ℃, effective sealing make motor protection grade for IPX8. Mechanical seal: Choose burgmann Germany mechanical seal, two way mechanical seal series independent work. Make motor and pump seal to space, for motor provides double protection. Pump side for tungsten carbide/tungsten carbide materials, motor side for graphite/silicon carbide. Oil room: Oil lubrication and cooling mechanical seal can be, and can prevent liquid penetrant to motor of the additional security function. A certain amount of air inside can reduce indoor pressure in the accumulation of oil rise.
WQ series submersible sewage is mainly used for municipal engineering, industrial building, hotel, hospital, civil air defence, mining and other industries, can be used to send row with solid particles and all kinds of long fiber sewage and waste water, rain and city life in the water.
Flow is 10 to 6000 m3 / h
Head is 6-62 m
For 0 ℃ temperature of the liquid-60 ℃
The maximum pressure 16 bar
1, with big port anti-clogging hydraulic parts design, greatly improving sewage capacity, can effectively through the pump fibre material 5 times of pump diameter and about 50% of the solid particles.
2, design reasonable, reasonable motor, high efficiency and energy saving effect.
3, the pump shaft by the corrosion resistance of chromium plating processing greatly improve axis, abrasion resistance, to the service life of the pump has a significant business.
4, cables and electrical connection with rubber overall vulcanization technology its long-term reliable waterproof effect.
5, mechanical seals and tandem seal is material for rigid corrosion tungsten carbide, has many characteristics, such as durable, wear-resisting, can make the safe running more than 8000 hours continuously.
6, compact structure, small size, mobile convenience, easy installation, without having to build pump room. Working while being submerged into water, and greatly reduce the project cost.
7, pump oil chamber equipped with oil-water probe, after the water pump mechanical seal side damage, water into the oil chamber, the probe signal, for pump protection.
8, according to user needs, equipped with automatic security control cabinet, the pump water embellish, double electric monitor, overload and over temperature, guarantee the pump running and reliable safety.
9, the double guide rail automatic FGC installation system, to pump installation, maintenance has brought great convenience, people can not for in and out of the sump.
10, float switch changes according to the required level, the automatic control of pump rev. Stop, do not need specialist care.
11, within the scope of use head run of motor load.
12, according to the use of the motor can be used outside the water jacket type circulating cooling system, can guarantee the electric pump in the condition of no water (thousand) safe operation.
13, installation with fixed automatic stick together and traveling free installation two kinds, can satisfy the use of different occasions.
