The transmission device comprises a power output shaft, a clutch block assembly, a clutch disk assembly, a transmission sleeve, a fire pump shaft, a secondary impeller and a primary impeller, and is characterized in that the power output shaft is fixedly connected with one end of the clutch block assembly through a semicircular key; the clutch disk assembly is arranged on the outer side of the other end of the clutch block assembly; the clutch disk assembly is fixedly connected with the transmission sleeve; one end of the fire pump shaft is fixedly connected with the transmission sleeve after being inserted into the transmission sleeve, and the other end of the fire pump shaft is connected with the secondary impeller through a spline; the secondary impeller is connected with the primary impeller through a spline. The fire pump assembled with the transmission device has the advantages of simple structure, rapidness and convenience in assembly, quick start and the like.
Description
Technical field
The utility model relates to a kind of fire water pump parts, relates in particular to a kind of transmission device of fire water pump.
Background technique
Fire water pump is requisite equipment in suppression system, is mainly used in city and industrial and mineral fire-fighting, but fire water pump flow of the prior art is large, and lift is not high, quality and bulky, assembling difficulty, during startup, needs the regular hour.Tracing it to its cause is because the transmission device complexity of fire water pump causes in prior art, therefore, needs a kind of fire water pump with simple drive mechanism, and the utility model is based on this proposition.
Model utility content
In order to solve the above problem existing in background technique, the utility model provides a kind of transmission device of fire water pump, and the fire water pump being comprised of this transmission device has simple in structure, assembles efficient and conveniently, and the advantage such as can start fast.
For achieving the above object, the utility model adopts following technological scheme:
A kind of transmission device of fire water pump, comprise pto＝power take-off, clutch block assembly, clutch disk assembly, drive socket, fire-fighting pump shaft, sencond stage impeller and one-level impeller, it is characterized in that, pto＝power take-off is fixedly linked by one end of woodruff key and clutch block assembly, the other end outside of clutch block assembly is provided with clutch disk assembly, clutch disk assembly is fixedly connected with drive socket, one end of fire-fighting pump shaft is fixedly connected with drive socket after inserting drive socket, the other end of fire-fighting pump shaft is connected with sencond stage impeller by spline, sencond stage impeller is connected with one-level impeller by spline.
The mode that is fixedly connected with of fire-fighting pump shaft and drive socket is: one end of fire-fighting pump shaft is fixed with spline, and spline is inserted in the inner core of drive socket and passes through locked with bolts.
Pto＝power take-off is the pto＝power take-off of motor.
The outside of described sencond stage impeller is fixed with locking bolt.
The beneficial effects of the utility model are:
1, both stage impellers is fixed on pump shaft by spline, and pump shaft is still first assembled in the pump housing, then sencond stage impeller and one-level impeller are installed respectively, is not subject to the restriction in space, easy to assembly quick.
2, pto＝power take-off and fire water pump pump shaft are not run-in synchronism, there is no load during machine hand pull starting-up, so start, are easy to.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the utility model embodiment 1 structural representation.
Embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the utility model is further described:
Embodiment 1
As shown in Figure 1, a kind of transmission device of fire water pump, comprise pto＝power take-off 1, clutch block assembly 3, clutch disk assembly 4, drive socket 5, fire-fighting pump shaft 6, sencond stage impeller 7 and one-level impeller 8, pto＝power take-off 1 is fixedly linked by woodruff key 2 and one end of clutch block assembly 2, the other end outside of clutch block assembly 2 is provided with clutch disk assembly 4, clutch disk assembly 4 is fixedly connected with drive socket 5, one end of fire-fighting pump shaft 6 is fixedly connected with drive socket 5 after inserting drive socket 5, the other end of fire-fighting pump shaft 6 is connected with sencond stage impeller 7 by spline, sencond stage impeller 7 is connected with one-level impeller 8 by spline, one-level impeller 8 outsides are fixedly installed locking bolt 9, the Placement of fire-fighting pump shaft and drive socket is: one end of fire-fighting pump shaft is fixed with spline, spline is inserted in drive socket and is bolted to connection, pto＝power take-off is the pto＝power take-off of motor.
Working procedure:
By engine output shaft, drive clutch block assembly to rotate, now pump shaft does not turn; When engine speed reaches the rotating speed that clutch throws away, the clutch block that is arranged on motor output terminal is thrown away under the effect of centrifugal force, contact with the clutch disk being fixed on pump shaft, drive clutch disk rotates, clutch disk drives fire-fighting pump shaft to rotate by drive socket, and then impeller rotation, thereby drive pump working.
