2-inch high-pressure fire pump gasoline Guiyang offer 2-inch high-pressure fire pump gasoline into the following categories according to the role of principle: 1. liquid mixing formula (including mixed-type and outer recirculation); 2 water ring wheel; 3 jets. type (including liquid jet and gas jet). Working gas-liquid mixing process is self-priming pump: As the special structure of the pump priming pump, after the pump stops, pump memory a certain amount of water, the pump starts again due to the rotation of the impeller, suction line of air and mixed and is discharged to the gas-water separation chamber, the upper chamber of the gas-water separator gas spill, the lower the water is returned to the impeller, suction line again and more than air mixing, until the gas pump and the suction tube completely discharged, complete self-absorption, and normal pumping. Self-priming pump is a water ring wheel ring and the water pump impeller combined in one housing, with the water ring round the gas discharges, to achieve self-absorption. When the pump is working properly, it can cut off the water wheel and pump impeller passage through the valve and release the liquid water inside the ring wheel. Jet pump, the 2-inch high-pressure fire pump gasoline and jet pumps (or jet) into, relying injection device, creating a vacuum to achieve suction at the nozzle. 2-inch high-pressure fire pump gasoline Guiyang offer 2-inch high-pressure fire pump gasoline parameters: KZ20HP 2-inch high-pressure fire pump gasoline unit type KZ20HP Importers diameter mm (inch) 50 (2 ") Rated flow (m3 / h) 30 maximum head ( m) 60 self-absorption time (s / 4m) 80 Maximum suction lift (m) 8 speed (rpm) 3600 fuel consumption (g / KW × h) ≤395 Dimensions (mm) 530 × 420 × 470 Weight (kg) 26 Engine Model KZ168F maximum engine power KW 4.8 (6.5) Fuel tank capacity (L) 3.6 Displacement (cc) 196 2-inch high-pressure fire pump gasoline Keywords: 2-inch high-pressure fire pump gasoline Guiyang offer 2-inch high-pressure fire pump gasoline | 2 inch Gasoline high-pressure fire pump manufacturers in the 2-inch high-pressure fire pump gasoline prices | 2-inch high-pressure fire pump gasoline Quote | 2-inch high-pressure fire pump gasoline lowest | 2-inch high-pressure fire pump gasoline | Diesel high-pressure fire pump | diesel water pumps | Gasoline water pumps | Diesel priming pump | 2-inch high-pressure fire pump gasoline Description: The first 2-inch high-pressure fire pump gasoline start, the right amount of liquid poured into the pump body, when the impeller rotates, the suction chamber and the impeller in the liquid through the impeller transported to the extrusion chamber go, the impeller inlet to form a negative suction valve open, suction gas pipe line through the suction chamber into the impeller and the impeller exit with the impeller rotating at high speed liquid phase mixing, on the role of the impeller, the gas-liquid mixture was pressed the chamber to the volume of the gas-liquid separation chamber big enough to go, because the flow rate decreases by the proportion of different liquids and gases and are separated by the pressure of the gas exhaust pipe, the liquid through the outflow channel back wheel rim. sequentially cycle, until the suction line gas is drained, whereupon the pump to complete the self-absorption process to work to achieve what .2 inch high-pressure fire pump gasoline work? ordinary centrifugal impeller if inhaled under the surface, Irrigation should be started in advance inconvenient memory in order to pump water, suction pipe imports need to install a bottom valve, when pump, hydraulic bottom valve caused great losses. The so-called pump, that is, before the start without irrigation (after installation The first time you start still require irrigation), after a short run, by the action of the pump itself, you can suck up the water, put into normal operation. 2-inch high-pressure fire pump gasoline Guiyang offer
