10 The tank shall be mounted on a auxiliary frame of ISMC 150 section and shall be adequately strength need to render it torque resistant. The auxiliary frame shall be manufactured to the size of the vehicle’s chassis and shall be of an all electrically welded construction. 1.3 THE HIGH PRESSURE JETTING PUMP The high pressure Triplex Plunger Pump shall be a fully variable unit with a heavy duty, positive displacement, reciprocating triplex plunger and having a discharge capacity of 226 LPM @ 130 bar pressure to perform the jetting function with a high degree of efficiency and reliability. The pump should be of Myers USA or Pratisolli Italy make with proven performance. The pump shall be suitably located on the chassis with provision for stopping the jetting pump without stopping the prime mover. The pump shall be equipped with pressure relief valve for protection and life extension of jetting pump. High pressure jetting system works on the principle of Hydro dynamic cleaning by water pressure suitable for cleaning, sewer lines of diameter ranging from 350 mm to 800 mm. The high pressure jetting system will be adequately protected by incorporating suction filter, relief valve and un-loader valves. Mounting of jetting pump shall be on the side of the auxiliary frame with the pump head facing upwards. 1.4 JETTING HOSE AND HOSE REAL. The hose reel drum should be of sturdy design and should be design to take a minimum 120 Mtrs. of 25 mm. internal diameter high pressure jetting hose. The hose reel drum should be given through a hydraulic motor. The rotation of the hose reel about its axis should be through a rotation of 180 Deg. The hose reel should be of the pivoted type inner core of hose should be constructed of special water grease resistance material. Thermoplastic Electrometric material core tube fiber braided reinforcement & should have abrasion resistant. Urethanes core the inner are should be water grease resistant material. Minimum Bend radius of hose should be 150 mm working pressure should be 172 bar and minimum burst pressure should be of 425 bar. The Jetting Hose should be Parker Only. 1.5 VACUUM PUMP The Equipment shall be fitted with a rotary sliding vanes type, positive displacement type Exhauster/Compressor known for its unmatched performance and for its trouble free and cost effective service through out the life of the equipment. The pump shall be fitted with high temperature resistant, asbestos free vanes, shall have a minimum free airflow displacement capacity of 13850 LPM The exhauster/blower shall be of an imported origin preferable of Jurop, Italy or MASPORT (USA) or MANNESMANN-DEMAG (GERMANY)
The exhauster / compressor will be provided with: 11 a. Convection air-cooling system b. Forced Oil Lubrication system c. Incorporated Check valve d. Incorporated 4 – way valve TECHNICAL DATA Delivery : Min. 13850 LPM free air flow Max Rated Vacuum : 90% Operating Vacuum : 200 bar (80% Vacuum) Operating Pressure : 1.0 bar gauge (absolute) The 4 – way change – over valve shall enable the unit to change quickly from the pressure to the suction mode and vice – versa. A pump inlet Filter of adequate capacity shall be incorporated in the system for the protection of the pump against any ingress of foreign particles, in both the suction and the overpressure modes of operation. Pressure relief and vacuum relief valves shall be line mounted to protect the equipment and system from over pressure and excessive vacuum respectively. The valves shall be factory set to control the operating pressure and vacuum parameters of the system. 1.6 SUCTION HOSE 5 sections of 100 mm dia. and 3 Mtrs. Long, heavy duty, lightweight, PVC hose along with quick connect hose-end fittings, shall be provided for the suction application. One, light weight hose-end suction nozzle with a suitable quick connect coupling shall be supplied with the equipment as a standard accessory. Two lockable hose racks for the stowage of hoses shall be provided on either side of the equipment. 1.7 PIPING System piping subject to high pressure should be of steel and forged steel fittings. These rubber connection hoses should not deform or get damaged due to compressed air heat generated when the equipment is used in the pressure mode. The pipes should be clamped sufficiently to absorb vibrations and should be easily accessible for maintenance. 1.8 CONTROLS All indicators and control elements required for control and monitoring will be located at a convenient operating position on the equipment and on the left-hand side of the vehicle.
