In the course of using the 300kw Cummins diesel generator set, we sometimes have a slow reaction or unstable voltage in a start-up unit, which causes the unit to fail to start and has to delay work, which indirectly affects the working efficiency of the diesel generator set. . At present, Hua Quan Power mainly describes the failure analysis during the start-up process of the 300 kW Cummins diesel generator set.
First, the 300kw Cummins diesel generator set when the voltage instability causes and solutions
1. The looseness of the wire connection solution: check the connection parts of the diesel generator set and repair it.
2. Control screen voltage-current selector switch failure solution: Replace the switch with the diesel generator.
3, the control screen voltage adjustment resistor failure solution: replace the voltage regulator resistor.
4, voltmeter failure solution: exchange voltmeter.
5, poor pressure regulator or regulator is not adjusted Solution: Check the regulator.
6. Excessive vibration of the diesel generator set Solution: Check the diesel generator set shock absorber equipment.
7, the engine speed is not stable Solution: Adjust or replace the engine fuel system parts to make it stable.
Second, when the unit is turned on, there is no response or rotation is slow and the solution
Possible Causes:
1, battery power shortage solution: check the battery charge
2. Solution for battery cable and pile head looseness: check and fasten the battery cable and pile head
3, the middle relay failure solution: check the middle relay action is normal
4, starter fault solution: repair starter
5, control box fault solution: check the control box inside the fuse and board line port fastening
The two problems mentioned above may be encountered by the user during the start of the 300kw Cummins diesel generator set. The most important solution is to carefully inspect the generator before use. It is better to find problems and solve problems before using the generator set. problem. Hope that the above introduction can bring users reference.
Slewing Drive
The slewing drive is a gearbox that can safely hold radial and axial
loads, as well as
transmit a torque for rotating. The rotation can be in a single
axis, or in multiple
axes together.
Slewing drives are made by manufacturing gearing, bearings, seals, housing, motor and other auxiliary components and assembling them into
a finished gearbox.
Slewing drives function with standard worm
technology, in which the worm on the horizontal shaft acts as the driver for
the gear. The rotation of the horizontal screw turns a gear about an axis
perpendicular to the screw axis. This combination reduces the speed of the
driven member and also multiplies its torque; increasing it proportionally as
the speed decreases.[2] The
speed ratio of shafts depends upon the relation of the number of threads on the worm to the number of
teeth in the worm wheel or gear.[3]
As technology has improved, more slewing drives are using
hourglass worm technology, in which the worm is shaped to engage more teeth in
the gear.[4] This
increased tooth engagement results in greater strength, efficiency and
durability.
