Sewage pump series: GW type pipeline sewage pump, sewage pump GWP stainless steel pipes

GW type no pipeline sewage pump is on the basis of the introduction of foreign advanced technology, combining with the characteristics of the use of domestic water pump and the successful development of a new generation of pump products, energy saving effect is remarkable, winding, no jam, automatic installation and automatic control, etc. Solid particles in the lining and long fiber waste, has a unique effect. This series of pump adopts unique impeller structure and new pattern in sealing, can effectively deliver a solid medium and long fibers. Compared with the traditional impeller, the impeller of the pump impeller with single port or shuangliu form, it is similar to a cross section of bending tube with the same size, has the very good flow, with reasonable volute chamber, make the water pump with high efficiency, the impeller through static balance test, for no vibration in the operation of pump. The pump hydraulic performance advanced, mature, the product tested various performance indicators are up to relevant standards, products put on the market with its unique efficacy, reliable performance, stable quality was welcomed by the masses of users and praise. A: no pipeline sewage pump product characteristics 1 GW type. for vertical single suction single-stage centrifugal pump, the centerline at the same level of imports and exports, import and export of flange is the same, so the disassembly is very convenient installation, cover an area of an area small, like the valve can be installed in any position on line. 2. and motor straight league coaxial, belongs to the electromechanical integration products, compact structure, stable performance. 3. 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. 4. Electric machine design is reasonable, reasonable, high efficiency and energy saving effect is remarkable. 5. Mechanical seal USES hard wear-resistant tungsten carbide, has many characteristics, such as durable, wear-resisting, can make the safe running more than 8000 hours continuously. 6. Hydraulic performance is advanced, the whole machine with high efficiency, low noise operation. 7. In motor wind leaf apex and protective cover, the machine can be placed in the outdoor work, without machine room, can save a lot of infrastructure costs. 8. In the use of head within the scope of use, with no overload of motor. 2: no pipeline sewage pump product use 1 GW type, factory business seriously polluted waste water discharge. 2, the urban sewage treatment plant drainage systems. 3, residential sewage drainage station. 4 drainage station, civil air defense system. 5, hospital, hotel wastewater discharge. June, municipal engineering and construction site. 7, exploration, mining machine. 8, rural biogas digester farmland irrigation. 9, waterworks water supply device. 3: no pipeline sewage pump using conditions 1 GW type, medium temperature shall not exceed + 40 ℃, intermittent use ( The longest do not exceed 5 minutes) To + 70 ℃, severe to 1. 0 to 1. 3 kg/dm3, PH value in the range of 5 ~ 9. 2, in their circulation cooling system pump, motor parts above liquid level less than 1/2. 3, under normal circumstances, the pump must be used within the scope of use head, ensure the motor load, however, if you need in total head within the scope of application, to be marked separately, with orders to manufacturers. 4, the motor current during operation shall not exceed the rated current of the machine. Four: GW type without pipeline sewage pump before starting to run 1. First of all check whether external fasteners loose in transit. 2. Check whether the power supply voltage is conform to the requirements of the motor nameplate. 3. Try to turn the power supply is connected to see if the impeller according to the instruction meaning in the direction of the turn on the pump, such as reverse direction, to any two phase of the cable line for can, try to turn the time cannot too long, so as not to burn the seals. 4. The pump is installed, the boot operation. Best can foot screws on the pump. Five: GW type pipeline sewage pump failure and ruled out 1. before use should check the motor winding insulation resistance of casing, such as less than 0. 5 ohms, just the stator must be drying, can be used only for insulation resistance increases. 2. body inlet of the clearance between impeller and oil seal, such as more than 2 mm abrasion resistant oil seal should be changed. 3. When there is leaking pump seal, should replace the seal in time, change when the first static seal flush solid loaded, then dynamic seal is installed on the shaft. 4. Replacement impeller, pull cable machine, can't use a hammer blow, so as not to damage shaft. Common fault reason 1. No water, by pumping liquid severely with the granularity is too high; Fluid flow blockage; Impeller to wrong; Bar stock draw in impeller are stuck; Pipeline export height than rated head height. 2. Insufficient flow rate, low head. Voltage on the low side, impeller to wrong or abrasion and sealing; Liquid severe granularity is too high. 3. Insulation resistance is low, ambient humidity, mechanical seal leaking badly.
