Commissioning and commissioning of ventilation and air-conditioning system in purification workshop

After the installation of the ventilation and air-conditioning projects in the purification workshop, each branch and sub-project must meet the construction and acceptance specifications and project quality inspection and evaluation requirements after the construction unit and the construction unit inspect the project quality; formulate trial operation, commissioning The scheme and schedule plan shall specify the construction unit and the person in charge of the trial operation site of the construction unit; the design drawings and equipment data related to the trial operation and commissioning must be complete, and you must be familiar with and understand the performance of the equipment and the main parameters in the technical data; the trial operation , The power such as water, electricity, steam and compressed air required during the commissioning period should have the conditions for use; the civil construction of the site where the ventilation, air-conditioning equipment and ancillary equipment are located should be completed, the doors and windows are complete, and the site should be cleaned; The manpower, material resources and instrumentation equipment required during the trial operation and commissioning can enter the site as planned.

Preparation of piping system: piping systems such as cooling water pipes, chilled water pipes, hot water and steam pipes should be flushed with water to discharge the dirt in the pipes, and check that there is no leakage; the refrigeration pipes should be ventilated and drained, and the air pressure test should be carried out. , confirm the tightness of the system; the valve on the pipeline is checked to confirm that the installation direction and position are correct, the valve opening is flexible; the drainage pipeline is unobstructed. Preparation of equipment and air duct system: Check the appearance and structure of ventilation and air-conditioning equipment for defects that have not been repaired; all equipment should be cleaned according to relevant regulations; add appropriate amount of lubricant to the running bearing parts and parts that need to be lubricated; check and adjust the opening and angle of the air valves and blades in the air supply and return ports; clean the air conditioners and ventilation ducts, check and adjust the action status of the air volume control valve, smoke exhaust valve and fire damper; check other air conditioners. The installation state of the accessory parts so that they reach the normal conditions of use. Preparation of the automatic adjustment system: Check the sensitive components, regulators and adjustment actuators after installation to confirm that their installation positions are correct, and the parts and accessories are complete; check that the wiring and piping of the primary and secondary instruments are correct; the automatic adjustment device After the performance of the device has been verified, it should meet the relevant requirements; the automatic adjustment system should be subjected to a simulated action test. Preparation of the electrical control system: the wiring in the motor and electrical box panel should be correct; the relay protection device should be set correctly; the performance of the electrical equipment and components should meet the requirements of the technical regulations; the electrical control system should be subjected to a simulated action test. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for purification workshops and clean workshops.

The preparatory work for the fan test operation is generally the appearance inspection of the fan and the inspection of the air duct system. After processing everything to be normal, make it reach the test operation conditions; check whether the fan, motor model, specification and pulley diameter are consistent with the design. Check whether the center of the pulley of the fan and the motor is in a straight line, whether the anchor bolts are tightened, check whether the flexible short pipe at the inlet and outlet of the fan is tight, and whether the tightness of the transmission belt is suitable; when turning by hand, the fan impeller should not be stuck. , check the flexibility of opening and closing of the fan regulating valve, and the reliability of the positioning device; check the reliability of the connection of the motor, fan, and air duct grounding wire; Then measure the running current of the motor. If the running current value exceeds the rated current of the motor, the total air volume control valve should be gradually closed until it reaches or is slightly less than the rated current value. If the fan is burnt out, its operating current value must be controlled within the rated range; during the operation of the fan, a metal rod or a long-handled screwdriver should be used to carefully monitor whether there is any noise in the bearing to determine whether the bearing is damaged or whether the lubricating oil is mixed with debris. After the fan has been running for a period of time, use a surface thermometer to measure the bearing temperature, which should not exceed the specifications in the equipment technical documents.
