Description
Technical field
The present invention relates to a kind of water pump, specifically a kind of self-priming pump of speedup, belong to pump technology field.
Background technique
At present, for driven the spraying implement 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, namely startup diesel engine moves water pump by belt driving band and carries out sprinkling work.Although this structure can both complete spraying operation, in actual use, there is the problem that efficiency is low, cost is high, specific as follows:
On the one hand, because the vibrations of diesel engine are large, axis, radial pull are large, and the words that belt is not strained easily are skidded, and belt too tightly will speed up the wearing and tearing of belt, and general work several hours belts will be rubbed, and need frequently to change belt, cost is high;
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, easily skidding occurs when adopting belt to connect, consider the impact that belt slippage brings, the rotating speed of water pump will not reach appointment rotating speed, and efficiency, lift all can be affected, and sprinkling falls flat, and range shortens.Meanwhile, As time goes on, belt wearing and tearing are more and more serious, and pressure is also thereupon more and more less, range, penetrate wide 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 widely 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 direct-connected, realized work and the stopping of water pump by the start and stop of diesel engine; This direct-connected efficiency is high, but the maximum speed of current domestic single cylinder diesel is 1900-2200, and the rotating speed that water pump requires is more than 2980 revs/min, therefore its turn up is less than requiring, cannot direct-connectedly mate.The rotating speed of multi-cylinder diesel engine is high, can meet rotation speed requirements, but powerful diesel engine drives little pump working also can cause the waste of resource.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of self-priming pump of speedup, can with diesel engine straight-connection, can guarantee that its spray effect is consistently, spray effect is little by the impact of time history, raises the efficiency, reduces costs simultaneously.

Preferably, described speedup box comprises housing, input shaft, output shaft, driving gear, driven gear, upper cover and capping, described output shaft is the input shaft of water pump, input shaft is parallel with output shaft to be placed in the speedup box shell that surrounds primarily of housing, upper cover and capping, and the gear transmission both being realized by driving gear and driven gear.
Preferably, described capping comprises capping B, capping C and capping D, and described capping C is fixedly mounted on the left side of housing, and described capping B and capping D is fixedly mounted on the right side of housing, and described upper cover is arranged on the top of housing; The right-hand member of described input shaft is successively through capping C and driving gear; On input shaft, the left and right sides of driving gear is separately installed with deep groove ball bearing I and deep groove ball bearing II; The left end of described output shaft is successively through capping D and driven gear, and on output shaft, the left and right sides of driven gear is separately installed with deep groove ball bearing III and deep groove ball bearing IV.
Preferably, also comprise coupling, described coupling is fixed on input shaft by interior hexagonal end Cock screw.
Preferably, described housing is connected with water pump by outer-hexagonal bolt III.
Preferably, described output shaft is also provided with water seal.
Compared with prior art, the present invention by by speedup box and water pump direct-connected, and by the axle Integral design of water pump spindle and speedup box, then diesel engine is connected to the end of input end, thus it is direct-connected to realize with diesel engine, the transmission of power is realized by gear-driven mode, rotation speed requirements can be met, its efficiency is high simultaneously, and guarantee that its spray effect consistently, spray effect is little by the impact of time history, raise the efficiency, there will not be because belt slippage weares and teares the many impacts brought, without the need to regularly replacing driving mechanism, cost is low.In addition, the blade wheel chamber of water pump can carry out water-cooled cooling to speedup box, lowers the temperature without the need to other equipment, guarantees to work long hours, reduces user cost further.
