Abstract
The utility model relates to an air blower, in particular to a diesel engine drive combination high speed air blower, comprising a centrifugal air blower, a gear speed increase box and a diesel engine, which is characterized in that a high elasticity friction clutch is connected between the output of the diesel engine and the input of the gear speed increase box, and the gear speed increase box is connected with the main shaft of the air blower via a shaft coupling. The utility model adopts a diesel engine to drive a multi-stage high speed centrifugal air blower, to prevent the production from interruption caused by power failure, and adopts a high elasticity friction clutch to replace the prior gear shaft coupling, to resolve the vibration damping problem of the diesel engine. The diesel engine drive combination high speed air blower has the advantages of simple structure, stable operation and reliable property, with wide application in areas lacking electricity power supply.
Description
Technical field
The utility model relates to a kind of blower, particularly a kind of Diesel Driven combined high-speed blower.It is mainly used in carries air, coal gas or other non-corrosiveness gas, is widely used in the gas delivery of industries such as metallurgy, chemical industry.
Background technique
Blower is a kind of gas transportation facilities commonly used, and it is widely used in the gas delivery of various industries.Large blower generally adopts the multistage high-speed blower now, and its structure generally by motoring, drives speedup box by gear coupling and realizes running up of blower fan as shown in Figure 1.The type blower fan requires coupling, speedup box and fan bearing all to need circulating oil lubrication, and when operation vibration and temperature requirement are higher, assemble and sealed precision stricter.The blower fan of this structure in a single day runs into sudden power or electric power resource shortage area all can't be used.And in some special industry, the blower of conveying gas is can not be out-of-work suddenly, big security incident will occur in case this situation occurs.Therefore inventing a kind of novel blower is highly profitable.
Summary of the invention
The purpose of this utility model is exactly the defective at existing blower, and a kind of Diesel Driven combined high-speed blower is provided, and it has solved the problem that equipment uses producer can't produce because of power failure.
The technical solution of the utility model is achieved in that it comprises centrifugal blower, gear speedup case and diesel engine, it is characterized in that: be connected with high-elastic friction clutch between the input end of diesel engine output terminal and gear speedup case, gear speedup case is connected with the main shaft of blower by coupling.
Belong to state's inner blower industry the first with the Diesel Driven high-speed blower, because of diesel engine speed is up to 1500r/min, the earthquake intensity of vibration equivalent is 14.2mm/s, and motor spindle nose vibration velocity is 2.80mm/s, and adopting vibration isolation measure is the key of key.The measure that the utility model adopts is: except that diesel engine itself band silicone oil damping shock absorption device (damping constant is 500Nm.g/rad), be vibration isolation measure to adopt the high-elastic friction clutch of LT100 between the input end of diesel engine output terminal and high speed speedup box, (the nominal moment of torsion is 11200Nm, maximum permissible speed is 2300r/min), substituted original gear coupling.
High-elastic friction clutch working principle: when being full of pressurized air in the cylinder (0.7～0.8MPa), cylinder and piston produce to the left and right separately and relatively move, meanwhile rubber assembly foreign steamer and internal cones also produce with respect to wheel in the rubber assembly and move axially, make friction plate be fitted on the external cone tightly, because the effect of frictional force, make driving and driven part bonding transmitting torque, otherwise when discharging pressurized air, friction plate is separated with external cone, be clutch separation, pressurized air provides (Q=0.42m by air compressor
3/ min Pc=1.25MPa), is used in combination with supporting QJ type pneumatic control system.This clutch is extensive use of during for prime mover at diesel engine, has following characteristics:
A. have reliable clutch function, guarantee the power transmission system starting under no load, reduce the starting-impact load, protection diesel engine and axle are transmission device.
B. have stronger momentary overload ability, guaranteeing can trouble free service under bad working environments.
C. have the torsional vibration of shafting frequency of adjustment and amplitude ability, the vibrational energy that all right absorption axes is reduces the amplitude and the stress that vibrate.
D. have certain compensation axis excursion capability, can compensate the error that centering is installed.
E. the joint of clutch or lock out operation are simple, rapidly, accurately, do not have " band row " phenomenon, and operation has remote control, collection control, the other control of machine and emergency maneuver function.
F. need not lubricate and cool off, maintenance easily.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 2, comprise centrifugal blower 1, gear speedup case 2 and diesel engine 4, be connected with high-elastic friction clutch 3 between the input end of diesel engine 4 output terminals and gear speedup case 2, gear speedup case 2 is connected by the main shaft of coupling with blower 1.The high-elastic friction clutch 3 that the utility model adopted is prior art products, and its model is LT100, and concrete structure as shown in Figure 3.
The utility model adopts high-elastic friction clutch to substitute original gear coupling, has thoroughly solved the damping problem of diesel engine.It has advantage simple in structure, stable, reliable performance, is highly suitable for electric power and lacks area production use.
