Installation of storage tank equipmentInstructions

gatePreparation before installation

1. Carefully read the drawings and deeply understand the design intent.

2. Develop equipment installation and commissioning plans based on the civil construction plan.

3. According to the actual construction period, a schedule for the arrival of equipment (including equipment ordered by the employer) shall be prepared. After consultation with the manufacturer, the specific arrival date of the equipment shall be reviewed and approved by the supervisor. The manufacturer shall strictly follow the schedule to ensure that the arrival date and order of the equipment and its components are in line with the construction plan, avoid confusion, reduce equipment inventory time and damage caused by storage, reduce warehouse capacity, do not affect installation, ensure smooth construction, and shorten the construction period.

Installation steps

Step: Safely lift the gate and weir into the well.

Step 2: Align the center of the gate opening with the center of the wellbore pipe opening and secure it with expansion screws.

Step 3: Install the hydraulic cylinder on the gate and place one end of the oil pipe on the hydraulic cylinder; Fix the protective tube of the liquid level sensor with expansion screws underground and place the liquid level sensor in it. Thread it out of the conduit along with the oil pipe to the well, and the installation is completed underground.

Step 4: Align the center of the opening of the hydraulic rotary barrier with the center of the reserved opening, and fix it with expansion screws. After fixing it, install the hydraulic cylinder on the gate, and at the same time, place one end of the oil pipe on the hydraulic cylinder. Along with the oil pipe, thread it out of the threading pipe to the well, and the underground installation is completed.

Step 5: Place the electrical control cabinet in the designated location and have professionals sequentially connect the electric hydraulic station, oil pipe, ultrasonic level gauge, and other components for control.

Installation process of barrier gate：

Align the center of the weir plate and frame with the center of the reserved hole, and fix the weir door to the wall.

Installation steps of barrier gate:

（1) Check the size of the foundation and clean up any debris in the grooves.

（2) Fix the base with expansion bolts at the bottom of the foundation pit and level it with a flatness control of ± 2mm

（3) Hang the barrier gate inside the well and use a lifting device to suspend the barrier gate, preventing the barrier gate frame from bearing any load.

（4) Adjust the adjustment screws on both sides of the barrier gate to make it vertical, with the verticality controlled within ± 5mm.

hydraulicsystemInstallation of

（1) Installation technical requirements

1) HydraulicsystemoffromCylinder assembly, hydraulic station and fluidpressThe control system, electrical system, pipelines, and foundation embedded parts should be installed, debugged, and tested according to the construction drawings and manufacturer's technical specifications.

2) The installation deviation of the hydraulic hoist cylinder support frame should comply with the provisions of the construction drawings. When the construction drawings do not specify, the coordinate deviation of the center point of the oil cylinder support should not exceed ±2mmThe elevation deviation shall not exceed±5mmThe horizontal deviation of the thrust seat ring of the floating supported oil cylinder shall not exceed0.2/1000The relative height difference between the two support surfaces or support center points of the dual suspension hydraulic hoist shall not exceed±0.5mm.

3) Before installation, a visual inspection of the oil cylinder assembly should be conducted, and the manufacturer's technical specifications should be compared to determine whether disassembly and cleaning should be carried out within the specified time limit. If it needs to be disassembled and cleaned due to overdue storage, the disassembly and cleaning plan shall be submitted to the supervisor for approval before implementation. On site disassembly and cleaning must be carried out under the comprehensive guidance of technical service personnel from the manufacturing plant.

4) Strictly follow the following steps and requirements for pipeline configuration and installation:

a. Before piping, the oil cylinder assembly, hydraulic station, and hydraulic control system equipment have been correctly positioned, and all pipe clamp foundation embedded parts are intact.

b. According to the construction drawings, piping and bending should be carried out, and the length of the pipeline joint section should be determined based on the actual situation on site. The pipeline layout should minimize resistance as much as possible, and the layout should be clear, reasonable, and arranged neatly.

installConstruction safety measures

（1）Establish a sound safety supervision mechanism, assign dedicated quality inspectors, and strengthen education on safety awareness and knowledge for employees. Adhere to relevant safety operating procedures, promptly address any issues discovered, and take preventive measures.

（2）Strengthen construction safety education for employees, provide job training for workers, and only those who pass the operation assessment can take up their posts.

（3）Strengthen the inspection, maintenance, and upkeep of construction machinery and equipment to ensure efficient and safe operation, and ensure that operators are certified to work.

（3）The installation and use of temporary power lines and facilities on the construction site must be carried out in accordance with the requirementsThe requirements of JGJ46-88 "Technical Code for Safety of Temporary Electrical Use on Construction Sites".

（4）The power lines must comply with the requirements of three-level distribution and two-level protection.

（5）Distribution boxes and switch boxes should be installed in dry, ventilated, and room temperature areas, with sufficient space and passage for two people to work simultaneously in the surrounding area. All distribution boxes and switch boxes are subject to exclusive responsibility, with doors equipped with locks, labeled with names and purposes, and marked with branch markings. The switchgear inside the distribution box and switch box must be intact and undamaged, with correct grounding, sensitive and reliable contact devices, and good insulation.

（6）High altitude operations must be equipped with protection and safety nets, and construction personnel must wear safety belts, helmets, and non slip shoes.The seat belt must be hung high and used low, and the hanging point must be safe and reliable.Isolation measures must be taken when performing cross operations.

Inspection and testing

Overview:Before shipment from the factory, the owner has the right to inspect and test all equipment and materials specified in this specification.

Before shipment, the owner should be promptly notified in writing to arrange for inspection.

The bidder shall provide the owner with the necessary facilities for inspection and testing, including labor, and shall allow sufficient time for inspection and testing.

All materials and equipment should be inspected and tested according to the owner's requirements. Bidders should anticipate potential delays in the inspection and testing of materials and equipment.

The manufacturer's representative should provide on-site service for installation inspection and equipment trial operation.

The on-site testing can only begin after the installation work and test preparation are completed.
