A sewer suction machine—also referre to as a vacuum truck or sewer cleaning truck—is a highly specialize vehicle designed specifically for the cleaning and maintenance of sewers. It is equipped with an exceptionally efficient and powerful vacuum system. Its primary function is to extract debris, sludge, and liquids from sewer lines, catch basins, septic tanks, industrial effluent pipelines, drains, and other drainage systems.
The Suction Unit mounted on vehicle comprises of the following:
The engine of the truck chassis is utilize to drive the vacuum pump through. A suitable drive arrangement through the side PTO of the truck gear box. Make: Bezares Alpha Drives
The cylindrical tank and dish ends are fabricated out of 5 MM MS Plates conforming to IS:2062 grade. The tank has a capacity of 4000 Ltrs. The tank is installed in an inclined position to facilitate flow of material towards the discharge end and is mounted on an appropriate sub-frame. Which in turn is bolted to the truck chassis.
Tank has blow – back arrangement for discharge of material from the sludge tank using the same vacuum-cum-compressor pump. The blow-back arrangement is more hygienic and cleaner way of evacuating. The sludge from the tank by pressurizing the tank when the pump is run in compressor mode.
The tank has arrangement for hydraulic tipping or blow – back arrangement for discharge of material from the sludge tank. The rear door of the sludge tank is fitted with hydraulic cylinders for opening and closing of the door. Adequate sealing and locking arrangement is provided to render the door leak proof.
The level indicator made of thick transparent acrylic tubing is provided on sludge tank in positions convenient for the operator to view. The tank exterior is spray painte with a coat of superior quality. Anti-corrosive primer and two coats of enamel paint of reputed make. The tank interior is coate with two coats of anti-corrosive epoxy paint.
The Exhauster / Compressor is of proven design with capacity of 6500 Lpm of airflow and is capable of generating vacuum of 90% Vacuum and alternatively pressure of 1.5 Bar. The unit is utilize for operating under vacuum for suctioning sludge through. A minimum 80 mm dia suction hose and alternatively in pressure mode for discharging by Blow back the sludge / silt from the tank without tipping /opening of the doors through a 4 way valve for change over from suction operation to pressure mode. Under the pressure mode, compressed air can be also injected into the sewer suction cum jetting machineAMP manhole, septic tank, etc for blow-back and agitate the sludge / slurry before suction.
Lockable type hose storage boxes are provided on either side of the tank to facilitate storage and transportation of suction hoses, tools, etc. 2 Nos. x 80 feet. Long heavy duty, PVC flexible suction hoses of minimum 80 mm internal diameter and fitted with quick action couplings are provided along with the equipment.
The entire unit is suitable for mounting on twin axle 9-ton GVW Truck Chassis with driver’s cabin and PTO Provision.
