DAS Series Submersible Waste Water and Sewage Pumps

Transcription

1 art DAS Series Submersible Waste Water and Sewage s ALICATIONS: ing of domestic and industrial sewage At sewage treatment plants ing of chemical and industrial waste water. ing of rain water All kinds of drainage and dewatering work. ing of difficult liquids of industrial processes. FLUID TYS: Unscreened sewage and other waste water types with high solids concentration. Water with sand content. Maximum grain size ( ). Liquid, sand ratio can be maximum %. For higher sand concentration preventive provisions must be taken against wear. Maximum allowed fluid temperature is C Maximum allowed medium density is 1, gr/cm, maximum allowed medium viscosity is 1, x - m /s. Measures must be taken to lower these values. DAS series pumps can not be used for pumping flaable and explosive fluids. TCHNICAL DTAILS: SUBMRSIBL LCTRIC MOTOR Turbosan DM type submersible electric motor operates with phase V AC (+/- % ) power supply. Insulation class of motors is F, protection class is I. H class insulation availble upon request. Motor Cooling : DM type submersible motors cooled externally by surrounding medium. In order to have sufficient cooling motor must be submerged up to the top. BARINGS : Rotor is supported by means of two heavy duty ball bearings. Bearings are grease lubricated, no need for maintenance for years of operation time. SHAFT SALING: Between motor and pumped fluid high quality (Silicon carbide Silicon carbide) mechanical seal is used, seals operate in oil chamber. ( DIN / N 17) Materials : component Material Motor casing volute casing Cast iron GG- (N-JL ) Shaft AISI impeller Cast iron GG- (N-JL ) Bolts Nuts Stainless steel Mechanical seal SIC/SIC NBR Cable H7RN-f Coating Coal tar epoxy paint over poxy primer 1 - V DAS / - V (Vortex) STR-1 ROTCTION RLAY: Special relay manufactured by Turbosan is very important part of submersible pumps and has to be fitted to the control system. MOTOR OVR HAT ROTCTION SYSTM : Stator windings protected against over heat by 1ºC termistors. Over heat usually caused by dry operation of the pump, excessive start stop frequency, or faulty electrical connections in case of over heat, pump tripped by relay and will not operate. WATR LAKAG WARNING SYSTM: Motor does not operate in case water leaks in to the motor. UM IMLLR: Single vane double angled non clogging impeller: These impellers have large solid passages, high efficiencies and they do not strain motor power at low discharge head values. Double vane impeller : For the discharge head values that can not attained with single vane impellers. They have smaller solid passages than single vane impellers. In some cases water must be screened. Vortex type impeller : This type of impellers do not have closed channels. Impeller located deep inside the volute casing. ing action is generated by vortex created within the fluid by rotation of the impeller. With this geometry they can tolerate large solids than other impeller types more specifically they tolerate fibrous materials in the pumped liquid. Disadvantage of this impeller type is lower efficiencies Ø Ø Ø Ø Ø Ø Ø Ø 9L C-L C- C ()

6 DAS Series s Installation Forms 1) AUTOMATIC COULING ( DUCK FOOT BND) Z: Reference axis ( guide rail center) It is economic and practical installation for stationary systems. Automatic coupling system consists of duck foot bend fixed on sump floor, guide rail (consists of two galvanized pipes connected in parallel) and fixing flange which is fitted to the pump. Automatic coupling set components and discharge piping have to be installed before sump get filled with medium. Fixing flange which is fitted to to the pump slides through the guide rails and pump lowered to the sump by means of chain. To take pump out of the sump by pulling pump by chain is enough, no dismantling or bolt removal required. Sealing is done by special gasket. Gate valve Non return valve Sump depth Front anchor bolts has to be inserted to grouting firmly. Note: D1 and D are minimum well diameters.
