Integrated Pump Station Technology Introduction

An integrated pump station consists of a top cover, a glass fiber reinforced plastic (GRP/HMPP) cylinder, a base, submersible pumps, a service platform, and pipelines, designed to meet the requirements for pressure boosting and water drainage.

One. Roof Cover

The integrated pump station cover consists of a fiberglass side cover and an openable pump station lid.

2. Cylinder

Integrated pump station's well section.

1. The top cover should consist of a fiberglass edge cover and an openable pump station lid. The lid material can be made from lightweight materials such as fiberglass or aluminum alloy.

2. The inner and outer surfaces of the lid should be smooth, free of cracks deeper than 2mm, and should not have any delamination, exposed fibers, resin nodules, foreign matter, or明显 uneven coloration.

3. The GRP/HMPP cylinder material should consist of a corrosion-resistant layer, a permeation-resistant layer, a structural layer, and an outer protective layer. The outer protective layer must be added with UV-resistant materials to prevent aging when exposed to sunlight.

4. The overall roof should have anti-slip measures. An anti-slip roof can be made of glass fiber.

5. The aluminum alloy material for the cover should be a non-slip patterned board, with a tensile strength of 120MPa or higher. The board thickness should be 5mm or more (excluding the pattern). The flange of the cover should be at least 20mm.

6. The glass steel pipes are made by using unidirectional glass fiber roving and its products as reinforcement materials, with thermosetting resin as the matrix, and are uniformly thick due to the computer-winding process. The Brinell hardness should reach 40HBa or more, the compressive strength should reach 120MPa or more, the circumferential tensile strength should be 150MPa, and the axial tensile strength should be 60MPa.

7. The lining layer includes the intermediate layer and the innermost layer, with a total thickness of not less than 2mm, where the thickness of the innermost layer is not less than 0.3mm. The thinness of the pipe wall should not be less than the nominal thickness specified in the approved drawings and technical documents according to the prescribed procedures.

8. The external cylinder of the integrated pump station should be equipped with at least two external lifting lugs.

Section 3: Base

Connected to the concrete slab to secure the parts of the precast pump.

1. The base should be a concave arc-shaped structure, with the inner side of the base pre-set or equipped with a mixer or粉碎 screen as needed by the design.

2. The base should have a tensile strength of 120MPa or higher and a Brinell hardness of 40HBa or higher.

3. The skirt edge of the base should have at least 2 casting holes, with the diameter of the casting holes reaching DN100 or more.

4. The base should have a concrete slab to resist buoyancy at the bottom, with the design dimensions of the concrete slab determined based on buoyancy calculations. For multi-well pump stations and structures at the front and rear ends of pump stations, it is advisable to use the same base. The concrete slab should have a cement strength grade of no less than C40, with rebar diameter not less than 10mm and thickness not less than 250mm. The concrete slab should be pre-bolted with anchor bolts for securing the prefabricated pump station after it is hoisted into the pit. The concrete slab can be prefabricated or cast directly in the foundation pit.

5. The base weight of the pump station should be ≥ 1.5 times the total weight of the pump to prevent vibration and resonance at the fixed connection points of the pump. For dry pump stations, select vibration-proof components based on the pump type.

Section 4: Mechanical and Electrical Equipment

Integrated pump station electromechanical equipment mainly includes pumps and their auxiliary equipment, debris removal equipment, pressure pipelines, valve equipment, and control systems.

1. Submersible pumps should be equipped with relevant production licenses and product quality certificates. The average failure-free operation time of submersible pumps should not be less than 2500 hours.

2. Submersible pumps should be securely connected to pipelines.

3. Pipe materials should be made of stainless steel. The material should comply with the current national standard "Welded Steel Pipes for Fluid Transportation" GB/T12771.

4. Pipeline accessories should be made of stainless steel.

5. The selection and connection methods of pipes, pipe fittings, and valves should comply with the provisions of the "Outdoor Drainage Design Code" GB50014 and the "Construction Quality Acceptance Code for Building Water Supply, Drainage, and Heating" (GB50242).

6. The material of the drainage pipe for the pipeline system should comply with the requirements of Code for Design of Outdoor Drainage System (GB50014) and Code for Construction and Acceptance of Water Supply and Drainage Pipeline Works (GB50268).

7. Drainage facilities should be installed at the lower sections of the piping.

8. A check valve should be installed after the pump in the piping.

V. Control System

1. The dimensions of the control cabinet should comply with the requirements of GB/T3047.1, which stipulates the basic dimensions of panels, racks, and cabinets with a height increment of 20mm.

2. The control cabinet surface should be flat and even, the welding joints should be uniform and firm, and there should be no obvious warping, bending, deformation, or burn-through defects.

3. Electrical and electronic components within the control cabinet must comply with the specifications of relevant product standards.

4. The internal wiring points in the control cabinet should be secure, and the wiring should comply with the design drawings and relevant standards.

5. The color of the conductors and busbars used in the control cabinet shall comply with the specifications of relevant standards.

6. The color of the indicator lights and buttons should comply with the specifications of the relevant standards.

7. The control cabinet's base should have mounting holes for securing to the foundation.

8. The top of the control cabinet should have lifting rings or similar for easy hoisting.

9. The protection grade of the control cabinet should comply with the provisions of the current national standard "Shell Protection Grades" GB4208.

10. The control cabinet should be equipped with various intelligent sensors, enabling unattended operation, programmable control, and remote control.
