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.

Food-grade 85 phosphoric ACID has a clear appearance and no odor. The liquid has a thick consistency and can be easily dissolved in water. The density of this chemical is about 1.67 kg/l. Phosphoric acid food-grade 85 is highly acidic with a pH level less than 1.
Properties:
colorless and transparent viscous liquid. It is odorless, sour, melting point 42.35 ℃, easily soluble in water, soluble in ethanol, can irritate the skin and cause inflammation, destroy body tissues, and have hygroscopicity.
Uses:
Used as sour agent and yeast nutrient, can be used as seasoning, canned, refreshing drink sour agent, used as yeast nutrition source when brewing, to prevent multiplication of bacteria.
Phosphoric acid is mainly used in the manufacture of various phosphate, such as ammonium phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, etc and condensation phosphate class.
It should be stored in a cool, ventilated warehouse. In high-concentration phosphoric acid, it is necessary to pay attention to heat preservation in cold regions in winter to prevent freezing and leakage of containers. Do not store and transport together with alkalis, toxic materials and other corrosive materials. Protect from rain and direct sunlight during transportation. Handle with care during loading and unloading. Violent impact is strictly prohibited to prevent the packaging container from rupturing. In case of fire, dry sand or dry powder fire extinguisher can be used for fighting.
