Through these procedures, the designer's qualification business ability can be controlled, and the design can be designed. The deceleration top is designed, and the design work is carried out through the 18, 9001 quality certification personnel.
The control process of the design process is electronically controlled during the design process. The element requirements of 13, 9, 01 are always under control. The composition of the task book design plan and the division of labor must have written materials. And it must be reviewed and approved by the relevant personnel; design input review. The review process is the same as the design input review. Completed design documents and paper. After rigorous review and approval, each document must have the approval personnel of the auditor's auditing personnel, and the proofreading audit shall be completed by the team, and the approval shall be completed by the department head or the chief engineer, and the approval shall be carried out by the center leader. therefore. In the design process, the layers are monitored and the information is eliminated on the paper surface, so that the design is creative and practical, and meets the requirements of the technical requirements of the quality requirements. Really become an excellent design.
The control of the trial production process is not only a new product new program, but also an old product old system improvement. After the design is completed, there must always be a prototype test and test. Taking the new product as an example, it must be strictly controlled during the processing of the prototype, and the process flow should be prepared according to the paper, and the material processing heat treatment should be carried out according to the technical requirements. These links must be reviewed and signed, and finally approved. The principle of the prototype test performance test life test application test is carried out under the supervision of multiple parties. Some of the judges have reported that they will sign conclusions, especially during the test, and the questions will be analyzed. The team will analyze and propose improvements to the revised design documents and report them to the supervisor for approval. After repeated iterations, until the product meets the requirements of the design task book, it can be mass-produced and officially promoted and applied.
The quality of the design can be guaranteed by the above control process.
3.2 Control of the production process The quality control of the production process is an important part of controlling the quality of the deceleration top, which is the responsibility of the production quality inspection department.
The production control plan for the production plan is issued by the production quality inspection department, and it is arranged and supervised. The quality of the production plan is directly affected by the production order. The production plan is not well executed, resulting in production chaos, which cannot make the production orderly, thus affecting the processing quality of the parts and the assembly quality of the finished products. After the production quality inspection department releases the plan on a monthly or quarterly basis, it regularly checks the production plan. The change plan must be signed by the relevant department and approved by the leader. At the same time, a written report on the previous production situation is made, so that the follow-up work interface is smooth and the production is carried out in an orderly manner. .
Controlling production quality from the source of production is the first step in ensuring product quality.
The material of the control part of the material is to ensure the control of the product quality, and the production quality inspection department controls the materials purchased by the production department according to the requirements of 1509001.
The first sub-contractor reviews, selects and evaluates the sub-contractors, determines the qualified sub-contractors, and requires the procurement department to order the various materials only in the qualified sub-contractors, and periodically reviews the qualified sub-contractors. Ensure that the materials purchased in the first purchase of the materials are subject to random inspection. Batch inspection of general materials, inspection of packing lists and test sheets.
Review the specification and performance of the material, etc.; review the certificate and product specification for the standard parts. Through the above sampling, the purpose is to control the material to meet the design requirements to control the processing technology to ensure product quality, to a large extent, the processing technology is a prerequisite. According to the requirements of 18,9,01, the production quality inspection department will conduct a comprehensive audit and check on the heat treatment technology of the process document processing process in the production department, and at the same time conduct regular review and write out the evaluation. The production department changes the process design, and the quality is required by the design department. The inspection department will sign and report to the center for approval, and the paper and document changes will be strictly in accordance with the change procedure. In addition, the production quality inspection department supervises and reviews production equipment such as machine tool heat treatment equipment assembly equipment inspection equipment, writes the conclusion of the review, and reports to the center for record.

If the unqualified person has the right, he has the right to propose replacement.
Inspection of the production process The inspection personnel of the production department conduct a comprehensive inspection of the processing of the parts. The production quality inspection department is responsible for sampling. According to the provisions of 1509001, the finished parts of each batch of parts and the production process, such as the machining of dimensional and dimensional tolerance heat treatment of a certain process, are sampled and sampled in proportion; the assembly process of the deceleration top and the finished product are also sampled in proportion. The found non-conforming products shall be recorded in strict accordance with the procedures prescribed in 9.1, and the production department shall be properly placed and properly marked. Then the production quality inspection department shall take the lead and organize relevant departments to conduct technical appraisal of the non-conforming products and make Handling of meaning. If the unqualified batches are sampled, the whole batch shall be inspected one by one, and the unqualified products shall be submitted for rework or concession to receive the scrapped processing intention. The handling intention shall be reported to the non-conforming product trial committee. After the discussion, after reporting to the center leader for approval, do The processing decision is made, and the production department is required to propose corrective and preventive measures and report to the non-conforming product review committee for approval.
Similarly, the non-conforming product returned by the user should also be controlled according to the above procedures, and the responsibility of the responsible person should be investigated.
The control of the factory inspection of the deceleration top product is subject to inspection of the processing quality and performance quality before leaving the factory. The quality of the processing is sampled by the production quality inspection department at the factory. After the batch is qualified, the quality inspection department will draw out several national inspection stations of the Jiaoha Center for performance testing.
According to the requirements of 150900, the inspection station regularly sends various detectors and testing tools to the national designated department for verification and calibration. Report the verification to the Science and Technology Management Section.
During the performance test of the deceleration top, the design department and the quality inspection department sent personnel to participate. Co-supervise the reliability of testing. The deceleration top mainly detects the critical speed of the braking work resistance of each parameter, and hundreds of data are measured for each top. All use computer automatic control, automatic measurement data automatically draw curves automatically test results. The whole process of detection is completed by the secondary instrument and computer software. For the detected unsatisfactory deceleration top. The relevant personnel shall perform the disassembly adjustment and carry out the sub-test. If it is still unqualified after the sub-test, return to the factory, the design department of the quality inspection department of the production department analyzes the reason, and reassembles all the deceleration tops of the batch, and writes a written report at the same time. The unqualified trial committee presented the reasons and processed the results.
The test station is correct, and the test results of the deceleration top are reported in detail and fed back to the production quality inspection department.
Quality Control of Construction Installation and Engineering Inspection 3.4.1 Installation of Quality Control Deceleration Top for Deceleration Top Installation It seems a simple process. but. According to the requirements of the 9 series. It is an important quality control link. Because the installation works well. Directly affecting the performance and quality of the deceleration top, such as the error in the mounting height can produce a deviation in critical speed. Therefore, the normal operation of the deceleration top is affected, so the installation quality is also strictly controlled.
30 D0 deceleration top passed the 809001 quality certification before each construction, the engineering construction department presses, 9, 1 program to do all kinds of technical preparations familiar with the design paper, master the installation standards. Understand the specific situation of the site to provide technical disclosure to the workers, and prepare materials and tools before departure. After arriving at the scene, first check the type and type of the deceleration top according to the paper requirements and the top mark. If it matches the paper, if it does not match, immediately contact the center dispatcher and make a record and wait for processing. Then check the power supply line and rails and prepare for construction.
During the construction process. Drilling the height of the installation height installation position, etc., strictly check the measurement according to the paper and installation standards. After the completion of each pass, a special person will be inspected and commissioned to meet the design requirements, and each top number will be recorded.
During the construction process. Every job must be documented, that is, traces are left in order to track the quality and achieve quality control.
3.4.2 Quality Control Engineering inspection and acceptance The final inspection of the quality of the deceleration top system is also the control of the quality system. The person in charge of the center of the user and the head of the engineering and construction department of the Department of Management and Development of the System Technology Department will participate in the inspection and acceptance of the project.
After the completion of the construction, the engineering and construction department of the System Technology Department will carry out the inspection and test. First of all, according to the technical requirements, check the installation situation of the deceleration roof one by one, and make detailed records, the user will sign after the consent of the user. then. Carry out the rolling test, push the peak at the speed specified by the design, and measure the speed of each point by using the combination of vehicles of different weights through the deceleration top. Check whether the safety connection rate of the connection rate meets the design requirements and the channel that does not meet the design requirements. To debug. Adjust the top critical speed and so on until the design requirements are met. Finally, the two parties signed the acceptance report, and the project was handed over to the user for formal investment, thus completing a high-quality customer satisfaction project.
3.5 Control of service quality After-sales service is the continuation of product quality. It is also the key to a good reputation for products. Therefore, according to the provisions of 18,9,1 according to the regulations of 18,9,1, the service personnel are strictly trained and certified, and the quality responsibility system is decomposed into people according to the quality policy of the center. Also. Reformed or supplemented the rules and regulations. For example, the telephone registration system users call carefully to make a good record, report to the user in a timely manner, and answer the user but the week; the user visits the system technical service personnel to be responsible for the division of labor, each package. Regular visits were made and found to be promptly processed, and the user intended to register. Report step by step. And tracking the processing results; on-site after-sales service system is on call, the user needs the timely delivery, the user needs help free and fast. In addition, there is also a training system for personnel in the warehouse maintenance system. Through the above various systems and regular review of service quality, we can achieve quality service and ensure the control of service quality. Not finished. To be continued on page 3, let's talk about it again, when converting 1 into actual circuit. A few questions to be aware of.
The relay output relays are isolated from each other; to avoid mixed line faults, the parking power supply is isolated. Because the 0 end of 1 is connected to the positive end of the power supply of the Ding 2 parking device, the terminal cannot be grounded to allow ungrounding; according to the method given in the manual, the slow-acting relay of 1 is connected to the slow-release relay in the middle; Relay response time D10, in order to prevent signal power conversion 0. This relay is powered down, the voltage holding device should be set at the power input terminal to meet the technical requirements.
