Avoid brute operations during installation. 6.3 Leakage prevention requirements: The entire greenhouse component parts are not allowed to leak, if the leakage exceeds 5, each leakage penalty is 50 yuan, and there is no condition to repair until there is no leakage, if there is no leakage in a greenhouse inspection, a shed incentive 200 yuan. 6.4 In the process of component installation, the front glass and back plate of the module shall not be scratched, and the scratched components shall be prohibited from being installed and shall be stored in isolation. There shall be no damage rate of the entire project components, and any damage to the components caused by all construction parties shall be compensated according to the price. Intentionally damaged, there will be additional fines. 6.5 Flatness of component installation: The height difference between adjacent components does not exceed 2mm, and the height difference between the east-west axis of the entire greenhouse area does not exceed 5mm. 6.6 Component edge height difference, height difference between adjacent components does not exceed 1mm. The entire plane angle of the assembly is 20° with a deviation of ≤1°. 6.7 Check whether the outer packing box is damaged before unpacking the components. In case of any damage, promptly notify the manufacturer, supervisor, material member, and site management technician to confirm on site. If there is no on-site confirmation, the damage of the components will be borne by the constructor. 7, pressure block installation: 7.1 At the same time as assembly installation or component installation, press the block to the size of the drawing. After the clamp nut is tightened, it must be “crossed†into the gutter. It is not allowed that the clamp nut has a “vertical†orientation. The block nut is divided into two sides, with the indentation surface above. 7.2 The installation of the pressure block must use the installation tools, the current installation tools for the wood, the installation personnel must have protective measures when installing the pressure block. The safety ropes must be secure and must be tied to the installers. They must remove the planks and safety ropes at any time with the installers. The safety measures are not in place, the planks and safety ropes are not removed, and a fine of 1,000 yuan is found. 7.3 The briquetting shall be installed in a timely manner. With the installation of the shed, if the briquetting of the construction teams is not installed in time, the components will fall down. In addition to the compensation for the loss of materials, the construction will be subject to additional fines. 7.4 It is not allowed to step on any part of the assembly during the entire briquetting installation and a fine of RMB 1,000 is found. Put people and heavy objects away. Bolt tightening force should be moderate when installing the clamp. 7.5 The pressure block should be installed in full according to the required quantity. No leakage pressure phenomenon is allowed. 8, leak-proof requirements: The entire greenhouse components do not allow leakage of the phenomenon, if more than 5 leakage points, fined 50 yuan for each leak, and no conditions to repair until no leakage. If there is no leak in one shed, the reward is 200 yuan. 9. Inspection and acceptance: The installation of the whole power station adopts the form of inspection and acceptance of the side of the installation. Each workman in the work needs to ensure that the self-test is qualified. After the installation is completed, a comprehensive inspection and acceptance is required. Fourth, quality requirements 1.

D-rings can typically be retrofitted into existing O-ring grooves with the size often based around the original O-ring size. The flat geometry on the base of the D-ring stops the seal from twisting and rolling, preventing spiral failure often seen when O-rings are used in reciprocating applications. D-rings can be manufactured to standard O-ring sizes, as well as custom sizes for specific applications.
