Yu Rui bulk canvas stretching machine bulk machine retractable canvas with ventilation, fire, smoke, noise, vibration isolation, and other functions, can be applied in soft and adjustable interface connected to the building exhaust system, is ideal for building smoke materials. It is characterized by good performance in high work pressure, gas flow rate of up to 20 m / s, long life, acid, alkali, oil, anti-corrosion, resistant to moisture, volume light, easy to install. First quality bulk canvas stretching machine inside smooth, beautiful appearance, breathable uniform, transport capacity, speed, stroke, dimensional stability, facilitate ventilation wear and long life, energy saving and environmental protection, installation, small footprint, work When no noise easy construction and other advantages, widely used: for directing gases, mechanical ventilation, chemical industry and industrial ventilation. Hot air soft connection to A-grade quality with a red silicone fiberglass fabric for the fabric, the inner circle of support to the wire, the suture (hot bonding) bead, lower, to enhance the adhesion and tensile connection: flange connection (angle , A3 steel, stainless steel), ferrule connection, so it has a high temperature resistance, can be used in a safe, thermal power plant: boiler, gas turbine exhaust systems, dust removal system. 2, petrochemical enterprises: boiler, industrial furnace flue gas desulfurization equipment. The factory produced canvas stretching machine for cement bulk bag (soft link) using cotton canvas 10 * 10 main material, bring φ5-8mm steel skeleton selection, wall thickness up to 1.5-3mm, specifications generally φ300, 320,350,400,650,720,840,1000,1240mm length is generally 1500,2000,2500,3000,3500mm I plant a professional circle sewing equipment, and its work; look beautiful, smooth interior workmanship, life can use millions of times back and forth.
