Technical instructions and steps

Technical Inspection Description: Debugging is the quality of the installation of the installation, the system’s work performance and the operational essentials, guaranteeing important work in normal operation, should have managers, technicians, operators together Participate, in the operation after the device is initiated, the equipment should be measured and recorded to ensure normal operation in the system in the future. 1. Debugging purposes: Check whether each unit device is operating normally or not. Checking the system running normally under cold conditions. Check the operation work is familiar with and master the operational essentials. 2. Debugging requirements: All motor turns correctly, the equipment load is normal, and the action is properly running for more than 2 hours. The circulating oil pump should be reflective before the water pressure test. Do a good job in debugging, timely exclude possible failures. Do everything preparation before debugging. Debugging Work is carried out in two steps of hot state. I. Cold debugging: After the boiler installation is completed, the cold debugging of each part is required, and the cold debugging must electric space heaters be operated by the company. II. Organic hot carrier furnace installation check acceptance: After all of the organic heat carrier furnace is installed, carefully inspector and acceptance of the host and subsidiary equipment, so that it meets the requirements of the ignition operation. 3. Pressure test: 1. Test: All heating systems are all tested after the standard is installed, the liquid phase heat carrier furnace is charged with 1.5 times the working pressure, use test The medium can not be used in water (using a special cleaning liquid YDJ to add in the furnace to add in the furnace. After the test is passed, the pressure is rinsed, and then use the compressed air to dry the water in the pot in the pot), because water The pressure test is not easy to clean the water to form a safe operation hazard. At the time of the test pressure, the temperature should be greater than 5 ° C, maintained at the test pressure for 20 minutes, and inspect the phenomenon of whether each coupling portion is leaked when it is reduced to the working pressure. 2. Qualified standard: The pressure test meets the following provisions as qualified: (1). There is no leakage trace on the metal wall and welds of the pressing element. (2). There is no visible residual deformation after hydraulic test. 3. Safety measures and precautions: (1) When the pressure test, the test site should have a particularly obvious isolation mark, and the idlers should not enter the test area. (2). During the pressure test, the pressure test operator should not stand in the flange and the front. (3). Personnel who have nothing to do with the test should not stand in the test area to stop watching.
