Quality problems and reason analysis of submersible electric pump industry

Pump industry generally exists in the following aspects of the main problems:

First, there are some problems in the main performance indicators. Pump flow head can not reach the labeled parameters, low efficiency, there is still a high standard, the phenomenon of chaos. Label not in the manner specified by the standard.

Two pump efficiency is low, the hydraulic model of the pump is flawed.

Three is the safety of the project problems. In the security category, the grounding measures are not in conformity with the specification of the specification, and the safety mark does not conform to the regulations.

Four is the appearance of rough, poor quality castings.

Five is the structure of a single, single function, low technology content.

Causes the above product quality flaw question mainly has the following several aspects the reason:

One is the technical condition of incomplete, outdated equipment, not enough processing equipment and testing equipment, process method does not correct, design documents deviation, testing method is not accurate, can not discover the problems and not take timely and effective measures.

Two is not enough understanding, can not accurately understand the standard terms, can not be strictly implement the requirements of the standard. For example, cable length, safety warning signs, the use of instruction safety content etc., these projects is often some small business out of the problem of multiple, seemingly simple, but if the standard is not enough to grasp, it is easy to appear unqualified, and of a very serious nature, belonging to an entire project failed. Therefore, once again, we should strengthen the study, we must seriously grasp the contents of the standard, in particular, should pay attention to the provisions of the safety standards. Avoid because of the negligence of the security project is not qualified.

Three is the quality management method is backward, the quality consciousness is weak, the management measure is not in place, the method is not accurate, appears the management aspect the loophole. Such as incoming inspection link, it should be to suppliers of any request, qualified supplier should determine how etc., you may only pay attention to the price of the product, largely ignoring the quality and technical requirements, always think, everyone in use will not have any problems. Because we test checks the adverse, in this part of the implied a lot of quality problems, if you really do not understand, can to some relatively large supporting the production of business consulting, let them help establish incoming verification, inspection method.

Four there is a man-made counterfeit. In order to meet the market demand, to increase competitiveness and man-made false targets. Main performance indicators are mainly refers to the flow head and pump efficiency, these parameters are the most concerned about the parameters of users, the general is also more attention, but why there are still many problems?

They think the main reason is that enterprises do not according to regulations were marked by tagging, also is to say, if realistic annotation, it will not appear a large number of the unqualified phenomenon, some enterprises in order to meet the needs of a normal competition, artificially exaggerated annotation, deliberately flow and head index of high standard, resulting in these projects failed. These phenomena can be avoided completely, therefore, we must resolutely put an end to the occurrence of this kind of phenomenon in the future business activities.

Five is the enterprise design ability is poor, the innovation consciousness is not strong. Many of the existing products, we can say that there is no technical content, is based on surveying and mapping, imitation, to sample processing, such as production, sameness of the product structure, low level of parts, single function, there is no guarantee of reliability, enterprises lack technical research and development capabilities.
