According to high standards and strict requirements, Southern Lianchuang provides efficient and high-quality services. A unit provides key sensor components for aero engines, and the leak detection accuracy requirements are very high, requiring 1.33x10-11mbar.l/s; Because each step in the production process must undergo harsh leak testing, each qualified product needs to be tested 100 times, so each test time must be completed within 4 minutes; Test accuracy and test time represent the highest level in today's industry. The maintenance of the equipment is the responsibility of the original engineer, but since the equipment purchase has been difficult to meet the requirements of test progress and test time for a long time, seriously delaying the customer's production progress, and having to purchase similar products from abroad at a high price every year; After the customer found Southern Lianchuang, Mr. Shen quickly found the problem: micro-leakage and instability under high precision caused by the ballistic flutter of the molecular pump. After careful debugging by Southern Lianchuang experts, the equipment meets the testing needs.

Southern Lianchuang leak detector maintenance advantages

1. High factory standards: high quality, strict requirements

Nanfang Lianchuang has veteran experts who contact helium mass spectrometry leak detector imported equipment in China, and our factory acceptance indicators can provide efficient and high-quality services according to customer requirements.

For example, the core components of the engine produced by a aerospace department, the component requirements test leakage rate is required to reach 1E-10mbar.l/s, and the test time is required to be 4 minutes; If the test local value does not reach 1E-5mbar.l/s within 11 and a half minutes, it cannot meet the requirements. The manufacturer's original maintenance set qualification index is 5E-10mbar.l/s, and the time is not limited. According to the customer's requirements, Nanfang Lianchuang Company has processed the key that affects local accuracy, such as air tightness, molecular pump, mass spectrometry chamber potential parameters, etc., to meet the customer's requirements for test accuracy and time, and solve the problems that have long plagued customers.

2. Short maintenance cycle: 7~10 days for non-critical failures.

Southern Lianchuang has a complete spare parts warehouse, general leak detector fault can be repaired within 7~10 days, greatly shorten the customer's waiting time, improve the customer's production efficiency.

3. Circuit component level maintenance,

Southern Lianchuang experts have in-depth understanding and research on the working principle, circuit, process, and vacuum leak detection of various helium mass spectrometry leak detectors, and have won praise from customers with their exquisite skills. For the failure of the mass spectrometry chamber, the engineers of the original factory are generally unable to do anything, and the general treatment method is to return to foreign maintenance standard replacement, the cost is high (close to 3,2 yuan), and the cycle is long (more than <> months, or even half a year).

Southern Lianchuang maintenance can achieve component-level maintenance of mass spectrometry room and circuit board. The original factory generally adopts the method of replacing second-hand spare parts as a whole, the price is high, and the customer does not know which parts have been replaced or replaced unnecessarily. Southern Lianchuang only handles the parts that need to be replaced or repaired, which effectively reduces the cost of customers.

4. Free testing, no testing fee, clear charges

In response to customer requirements, Southern Lianchuang provides free equipment testing, does not charge any fee, and then gives accurate quotations. The maintenance cycle is generally 5~10 days except for major faults such as mass spectrometry room damage, which is much shorter than the maintenance cycle of more than 2 months of original factory maintenance, so as to minimize the production loss caused by the customer's shutdown. In the case of a very urgent customer, Southern Lianchuang can provide production backup and only charge an appropriate fee.

5. After-sales value-added services

a) Remote technical support:

Southern Lianchuang provides 5*8 remote telephone technical support and remote technology output services free of charge; Assist customers to request to the original factory to speed up the after-sales service response speed and shorten the maintenance cycle.

b) On-site service:

I. Equipment inspection on-site service, provide equipment operation status, provide diagnosis and testing report and technical advice, and provide regular equipment maintenance services.

II. Provide accurate calibration services. Southern Lianchuang provides a variety of professional leakage bottles with leakage rates, and provides accurate calibration services for customer-specific leakage rates (10-3~10-12 ATM-cc/sec or mbar.l/s).

c) Factory maintenance:

Southern Lianchuang provides customers with factory-level maintenance quality, repaired and replaced parts provide a 6-month warranty, and provide faster response speed and competitive price.

(i) Professional maintenance technicians, skilled engineers with more than 10 years of maintenance experience;

(II) REPLACE ONLY DAMAGED PARTS, AND CHARGE ONLY APPROPRIATE LABOR COSTS FOR FAULTY PARTS THAT CAN BE SOLVED BY TECHNICAL MEANS SUCH AS CLEANING;

(III) THE MAINTENANCE CYCLE OF SOUTHERN LIANCHUANG FACTORY IS SHORT, GENERALLY LESS THAN 10 WORKING DAYS.

(IV) PROVIDE FAST EQUIPMENT STATUS ANALYSIS AND DETAILED QUOTATION FOR THE EQUIPMENT SENT BY CUSTOMERS TO SOUTHERN LIANCHUANG FOR MAINTENANCE, AND DO NOT CHARGE ANY FEES IN ADVANCE, SO AS TO FACILITATE CUSTOMER EVALUATION.
