How to maintain corrosion-resistant plastic chemical pumps in winter?

　　With the lowering of the temperature in winter, many occasions of sewage chemical transfer pumps due to the temperature stop using, this time the chemical pump overhaul and maintenance has become particularly important, the following will share with you the repair and maintenance methods of chemical transfer pumps in winter.

　　First, corrosion-resistant plastic chemical pumps in winter if out of service, we have to plastic chemical pumps and pipelines in all the water discharge, to avoid cooling period, water or ice to the pump body freeze cracked, and will be the pump body shell of the dust and soil wipe clean.

　　Second, corrosion-resistant plastic chemical pump parts maintenance is also key Oh! Such as impellers, mechanical seals, bearings, seals, check valves and other wear parts also need to be checked regularly, try to spare some, can be replaced in the event of failure, such as found to have serious wear and surface rust spots, should be replaced in a timely manner, and then coated with wheel-slip oil, under normal circumstances, corrosion-resistant chemical pump fittings are precision abrasive injection molding, the life of the pump is still quite long.

　　Third, due to the low temperature, may seriously affect the motor internal lubrication, lubrication is not enough words will appear bearing wear and so on, is the use of the motor itself the principle of heat, in its vents out of the paste the appropriate size of the film, this can effectively control the entry of cold air, at the same time, the motor produces enough heat to make its internal lubricating grease normal work.

　　Fourth, the disassembled screws with diesel fuel to clean, coated with oil, and then reinstalled, can be placed on the rust or corrosion.

　　Corrosion-resistant plastic chemical pump maintenance tips

　　First, after the corrosion-resistant self-priming pump stops running, make sure that the internal liquid is emptied, check whether the pipeline is sinking, if there is water stored in the place to be drained, to ensure that there is no accumulation of water in the pump body, in order to prevent the pipeline from icing.

　　Second, corrosion-resistant self-priming pumps such as in outdoor environments, can be covered with used towels, clothing outside the pump trade, to achieve the effect of heat preservation, after all, our pump baby is also to temperature.

　　Third, for already frozen pumps, water pipes, do not wait for the ice to melt to open the pump, which is likely to cause damage to the corrosion-resistant self-priming pump or mechanical failure.

　　Fourth, on the Guobao pump corrosion-resistant plastic self-priming chemical pump thawed, it is recommended to use a hot towel on the water pipe, and then use warm water to sprinkle thawing, do not bake with fire or with high temperature boiling water, when high temperature hot water and very low temperature ice combination, inevitably cause the pipeline or the pump body cracking!
