How to use QDLF stainless steel light vertical multistage pump
QDLF stainless steel light vertical multistage pump has been designed and manufactured by non-self-priming vertical multistage centrifugal pumps with advanced technology at home and abroad. It is easy to replace with standard vertical motor and quick-loading mechanical seal. A good instrument, but also to use, reasonable use of the instrument can effectively extend the service life of the instrument, to avoid failure, let Xiaobian share with you about how to use reasonable QDLF stainless steel light vertical multi-stage pump . How to Use QDLF Stainless Steel Light Vertical Multistage Pumps Before starting work on the pump, make sure that no power is supplied to the pump and that the pump can not start abruptly. Pump bearings and shaft seals are maintenance free. If the pump does not have to be drained for a long time, you can remove one of the coupling guard, inject a few drops of silicone oil between the pump head and the shaft of the coupling. This will prevent shaft sealing surfaces from sticking. When attaching the coupling guard, note that they are centered vertically in the recess of the pump head. Before the pump starts working, make sure that no power is supplied to the pump and that it is impossible for the pump to start abruptly. Vertical stainless steel multistage centrifugal pump bearings and shaft seal is not required for maintenance. If the pump does not have to be drained for a long time, you can remove one of the coupling guard, inject a few drops of silicone oil between the pump head and the shaft of the coupling. This will prevent shaft sealing surfaces from sticking. When attaching the coupling guard, note that they are centered vertically in the recess of the pump head. Motor bearings: Motors that do not have a lubrication nipple are not required for maintenance. The motor with a lubrication nipple should be lubricated with high-temperature lithium-based grease. If the motor is used on a season-by-year basis (motors not used for more than six months in a year), it is recommended that the pump and motor be cleaned and lubricated once they have been left unused. During the frost protection frost pump shelved do not, it should be drained to prevent damage and cracking. Loosen the exhaust screw on the pump head and remove the drain plug on the base to drain the pump. After the water has been drained off, the removed parts should be refitted in place or properly stored. Note that the fluid that is discharged will not cause injury to persons or cause damage to the motor or to other components. In hot water installations, special attention is given to the risk of scalding caused by hot water. Do not tighten the vent screw and replace the drain plug until the pump is not used again. Swing the by-pass valve against the stop before returning the drain plug to the base. Install the drain plug by tightening the large coupling nut attached to the bypass valve. The repacking procedure is still disassembled. Further reading: Canton Fair IFAT China building water pump manufacturers ranking ptc Show article belongs to Internet industry (Xiamen) Co., Ltd.
