Description
Technical field
The utility model relates to a kind of water pump, the specifically vacuum primingpump of a kind of speedup, belongs to pump technology field.
Background technology
At present, for drive the spray appliance of pump working by diesel engine for, mainly diesel engine is fixed on support, then utilize belt sleeve on the belt pulley of diesel engine and the belt pulley of water pump, realized the connection of diesel engine and water pump by belt, start diesel engine and namely undertaken spraying work by the dynamic water pump of belt driving band. Although this kind of structure can both complete spraying operation, but in actual use, there is the problem that efficiency is low, cost is high, specific as follows:
On the one hand, owing to the vibrations of diesel engine are big, axially, radial pulling force big, the words that belt is not strained easily are skidded, and belt too tightly will accelerate the abrasion of belt, and general work several hour belts will be disconnected by mill, it is necessary to frequently changes belt, cost height;
On the other hand, because the appointment rotating speed of country's setting water pump is more than 2980 revs/min, when not reaching this rotating speed, its efficiency can decline, and pressure, flow, lift will not reach required value yet. If the diameter of diesel engine middle belt pulley is 165, the diameter of water pump middle belt pulley is 110, and in theory when the rotating speed of diesel engine is 2000 turns, the rotating speed of water pump is about 3000 turns, can reach appointment rotating speed; But in actual mechanical process, when adopting belt to connect, skidding easily occurring, it is contemplated that to the impact that slipping of belt brings, the rotating speed of water pump will not reach appointment rotating speed, and efficiency, lift all can be affected, spray and do not reach desired result, range shortens. Meanwhile, As time goes on, belt abrasion is more and more serious, and pressure is also thereupon more and more less, and range, to penetrate width more and more lower, as: the range originally adjusted is 35m, penetrates the wide new loom for 70m, and As time goes on, it is penetrated and wide will not reach 50m.
But, can also be connected by direct-connected mode between diesel engine and water pump, namely the output shaft of diesel engine and the input shaft of water pump are direct-connected, are realized work and the stopping of water pump by the start and stop of diesel engine; This kind of direct-connected efficiency height, but the highest rotating speed of current domestic one-cylinder diesel machine is 1900-2200, and the rotating speed that water pump requires is more than 2980 revs/min, therefore its rotating speed does not reach requirement, cannot direct-connected mate. The rotating speed height of multi-cylinder diesel engine, it is possible to meet rotation speed requirements, but high-power diesel engine drives little pump working also can cause the waste of resource.
