on January 16, 2019, the official of Taizhou Municipal market supervision administration announced the results of special supervision and spot check on product quality of Taizhou Municipal manufacturing industry in the fourth quarter of 2018, and two batches of submersible pump products were unqualified

on January 16, 2019, the official of Taizhou Municipal market supervision administration announced the special quality supervision and spot check results of Taizhou Municipal manufacturing products in the fourth quarter of 2018. If they tilt to the right, the angle between the vertical line of the toothed rod and the push rod will increase. Two batches of submersible pump products are unqualified

recently, according to the product quality law of the people's Republic of China and the regulations of Zhejiang Province on product quality supervision, the former Taizhou Municipal Bureau of quality and technical supervision organized a special supervision and spot check on the product quality of municipal manufacturing industry in the fourth quarter of 2018, and conducted a spot check on 58 batches of products from 58 enterprises in Taizhou, 56 of which were qualified, with a batch qualification rate of 96.6%

how to select these parts? The results show that the "safety mark" items of 2 batches of submersible pump products are found not to meet the requirements, and the production enterprises involve Zhejiang sulang electromechanical Co., Ltd. and Zhejiang Zhongde Weier Electric Co., Ltd

consumer guide for submersible pumps:

when purchasing pump products, consumers should grasp the following points:

one choice, choose regular supermarkets or specialty stores, and choose brand products; The corresponding (matching) products shall be selected according to the flow, head and service conditions. Generally, the pump head = vertical height difference from the water surface to the water outlet + pipeline loss + outlet pressure + safety margin (10%), which shall be reasonably selected according to the submersible pump's suitability for underwater work

second, check whether the appearance is intact and whether the product logo is complete. The product label is the first-hand information for users to select water pumps and understand the performance of water pumps. It is the necessary information to guide consumers to correctly purchase, use, maintain and maintain products. Signs are necessary information to guide users how to use the product correctly. If the label is not complete, it may cause the user's misoperation. The standard stipulates that in addition to indicating the product model and specification, the water pump should also be marked with the technical parameters, production date and factory number of the supporting water pump. In particular, the enterprise does not indicate the factory number, which brings certain difficulties to the after-sales traceability of the electric pump

three checks: check the inspection report issued by the relevant inspection institution when purchasing

four tests: simple plug-in no-load test should not be carried out for too long to check whether it can operate normally and whether the situation is not optimistic about whether the noise and vibration are severe; Before the water pump is used, the megohmmeter shall be used to check the notch projector of the motor insulation resistance impact sample, and the minimum value shall not be less than 50m Ω (cold state)

five functions: correctly install and use the water pump. If the cable should be overhead, the power line should not be too long; Try to avoid running at low voltage; Do not overload for a long time; Pay attention to regular inspection and maintenance
