Service

In order to ensure that the products have been debugged to an optimal state, our company has prepared the relevant operational specifications and quality management documents for on-site commissioning. All of the process standards, materials and processes in the commissioning process are in a controlled state, so that all links of debugging are strictly in accordance with the drawings. , process requirements.

Main debugging project

1. The user is responsible for organizing the water, electricity, gas installation and other engineering facilities and sites required by the equipment. Our engineers check whether the user site has met the equipment installation requirements and whether the site and installation facilities are available, especially the air compressor and the dryer. Good ventilation in your location.

2. Check with the user whether the contents of the arriving user's equipment are complete or not, and whether the equipment has been damaged due to transportation or loading and unloading.

3. Check the installation quality of the equipment, including the electrical control system, air pretreatment system, air separation system, alarm system and its end detail quality.

4. Test equipment gas pressure, flow, purity and other performance indicators.

5. Test equipment adaptability to various variable conditions or other external adverse conditions to ensure that the unit can operate normally.

6. Adjust the equipment to the state of the user's requirements to make the equipment as low-load and low-energy operation as possible.

7. Perform a thorough inspection and on-site maintenance of the equipment.

8. Product acceptance. With reference to the contract, the product and the function acceptance are jointly performed with the user, and the acceptance certificate is signed as the device acceptance certificate.

In order to enable users to more accurately grasp the operation specifications and maintenance methods of the air-gauge equipment, ensure the long-term stable operation of the system, and increase the service life of the equipment, Qihong has always attached great importance to user training and has formed an effective training method.

Clear equipment owner

Qihong air separation equipment has the characteristics of simple and easy to use, simple daily maintenance, but air separation equipment as part of the company's production, but also has a long service life, can not easily downtime in the production process, according to product characteristics Requires professional responsibility, and we recommend that the use of the organization's technically responsible engineers should be responsible for the use of the product (part-time can also be).

Scientifically develop training content

After the installation and commissioning process of the equipment is completed, the engineers of Haihong will provide professional training for the staff according to the situation of the users. The training content mainly includes “Introduction to Equipment Principles”, “Introduction to Equipment Structure and Function”, “Operation Guide”, “Maintenance Guide for Equipment”, “Maintenance of Equipment Site”, “Analysis and Solution of Equipment Usage Problems”, etc. Independently skilled equipment operation, maintenance and simple troubleshooting, to achieve the "three understand three sessions" standard, that is, "understand the principle, understand the structure, understand the use, will operate, will maintain, will rule out the general failure."

Good customer service support is an important guarantee for protecting user investment, system efficiency, and system efficiency. Qihong Company has a professional engineering and technical team with experience in equipment maintenance and system integration. They will provide you with the most professional technical and service support at any time.

  • Pre-sale user research
  • Before the signing of the contract, the sales engineer of our company will communicate and research with the user's engineers. According to the user's needs and the actual situation of the site, we design the best solution that meets the multi-faceted demands of customers. 
  • Professional Training
  • Our professional engineers complete the installation, commissioning and related application training of the entire equipment. 
  • Fast service
  • After receiving the customer's repair, our engineers responded within 2 working hours and arrived at the customer's site within 48 hours. 
  • Warranty period
  • Our company provides a one-year warranty on the equipment provided by Qihong Company. The warranty period starts from the acceptance date. During the warranty period, the replacement of spare parts shall be approved by the air-engineering engineers. The replacement of machine parts is free and the quantity is free. Replaced parts are handled by Qihong. During the warranty period, Qihong provided a free upgrade of the system software of the device. After the warranty period, Qihong will continue to provide quality after-sales services.
  • Create a computer file
  • Each device has a unique number. Both the user and the company have a computer profile. At the same time, the user is reminded to record the operating conditions of the equipment at regular intervals as required, update the equipment's file information, and improve the equipment's information management.
  • Regular call reminder
  • Periodically remind users to carry out maintenance, replacement of wearing parts, and related precautions; irregularly conduct product use tracking service surveys and after-sales service consultation. 
  • Customer tracking visits
  • In addition to daily repair services, Qihong will provide a free system maintenance service. This service time is determined by the engineers and customers. Regular maintenance services include machine inspections, performance tests, and necessary mechanical or electrical adjustments. The return visit service helps Qihong to understand the usage of the equipment, conduct consultation, diagnosis and failure prevention and prevention of the equipment's operating condition, and put forward a reasonable maintenance plan to help users better maintain and use the equipment.
  • Part Discounts and Inventory
  • Qihong Company maintains a sufficient inventory of system components for this type of equipment, while providing users with preferential supply of equipment parts and free equipment technical consulting services.

Establish a correct concept of maintenance, and pay enough attention to maintenance. Good operating practices and regular maintenance can extend the normal service life of equipment, reduce energy consumption, and reduce maintenance costs. It can also effectively prevent sudden failures and significantly reduce the negative impact of failures on production.

Daily use precautions

  • 1. Normal supply and normal opening and closing of the power supply, water supply, air supply and temperature conditions required by the machine; especially the stability of the power supply voltage, if necessary, a voltage regulator can be installed to reduce the power supply problems to the controller and the electromagnetic system. Damage to the valve.
  • 2. Pay attention to the inlet air volume, temperature and pressure of the dryer at any time, and keep the evaporation pressure of the dryer between 0.4 and 0.5 MPa and do not exceed the rating.
  • 3. Inspect the automatic drain valve of the filter and the automatic drainer of the cold dryer every day to avoid clogging and loss of drainage and sewerage.
  • 4. Check whether the heat sink of the dryer is clean on a weekly basis so as not to adversely affect the effectiveness and life of the dryer.
  • 5、According to the requirements of the instrument use code for operation and routine maintenance, irregularly check the sensitivity of solenoid valve/pneumatic valve, pressure range of pressure regulator, accuracy of gas analyzer, compression of adsorption tower, exhaust condition of muffler, Flow meter inner tube cleanliness and so on.
  • 6. Check the heating components of the purification equipment, the electrical control system, the amount of hydrogen, the flow rate of the regeneration gas in the drying tower, and the temperature and time of regeneration.
