Introduction

The Wall mounted penstock is a rectangular stainless steel frame structure. The driving device is installed on the beam of the gate frame, and the door frame is installed on both sides of the pool wall. Door panels, door frames, guide rails, screws and driving devices should have sufficient strength and rigidity, and their tensile, compression and shear strength safety factors should be greater than 5 to ensure the normal operation of the equipment.

Product details

Material of main parts

Door panel, door frame, guide rail, gate screw: stainless steel

Sealing strip: Nitrile rubber

Electric device: Changzhou

Product Advantage

1. The Wall penstock has sufficient strength, rigidity and tightness

The Stainless steel Wall penstock is provided with a well-shaped rib on one side to increase the strength, and the water facing surface is a flat plate, and the seal of the gate is sealed with rubber. The manual opening and closing device is driven by screw and nut, and the screw is made of stainless steel, which can automatically adjust the swing of the screw during transmission without damaging the seal of the gate.

2. The Wall penstock has anti-corrosion characteristics

Non-metal and non-ferrous metals are not coated with anti-corrosion paint. Before painting, the remaining parts should be cleaned of burrs, oxide scales, rust spots, sticky sand, scars, and oil stains. The gates, risers, fleshy and sharp edges, etc. should be shoveled and sandblasted. The level of surface treatment It is Sa21/2 level.

3. The Wall penstock is light, strong, beautiful in appearance and easy to operate 

The Wall penstock  structure is made as light, strong, beautiful in appearance and easy to operate as far as possible while meeting the rigidity requirements. If manufacturers have better suggestions and newer products, they can provide options, but they must be confirmed by the owner and engineer. The opening and closing device must be directly installed on the upper part of the mast, and the height should satisfy the manual operation handwheel.
