Wood pulling excavator refitting hydraulic winch 3T hydraulic winch Yuansheng manufacturer direct selling

  Wood pulling excavator refitting hydraulic winch 3T hydraulic winch Yuansheng factory direct selling main features: 1 The fixed geometric position relationship between driving components determines the design layout of the system, and the layout changes little; 2
the size of the transmission system is large and the total weight is heavy; 3
the installation layout is complex, and the plane and precise component positioning often need finishing; 4
it is difficult to realize large-scale stepless speed regulation; 5
it is difficult to realize smooth reverse rotation under load; 6
the maximum torque can be generated under locked rotor operation by using hydraulic coupling; The electric drive winch uses the motor as the source power to drive the drum to rotate through various transmission mechanisms
Main features: 1 The specified speed motor drive method is adopted on small or low-end winch products, which can realize single speed (or double speed) and two-way rotation functions
The system is simple, but it can not start at low speed and change speed smoothly; 2
AC variable frequency speed regulation mode is adopted to realize stepless speed regulation from zero to maximum speed, which can provide 100% rated torque under low-speed and locked rotor conditions, and the speed regulation is stable

the equipment is complex, and the technical level of maintenance personnel is required to be high
In the hydraulic system, some hard dust and metal debris are often left in the machining process of the hydraulic components, and the external dust, dirt and particles are often immersed in the hydraulic system
The hydraulic components are worn out to precipitate iron dust, and the oxygenates of the hydraulic oil will produce impurities
When the impurity particles in the hydraulic oil reach a certain size, the steam hole will be blocked, and the moving parts will vibrate violently and get stuck, which will affect the normal work of the hydraulic system and shorten the service life of the hydraulic workpiece
Therefore, unclean hydraulic oil is often the main cause of hydraulic machinery failure
In order to ensure the normal operation of the hydraulic system and improve the service life of the hydraulic components, the oil entering the hydraulic system must be filtered through the oil filter
The oil filter shall meet the following requirements: high filtration capacity and low pressure loss; Sufficient oil passing capacity; The filter material has sufficient strength to prevent damage due to hydraulic pressure; It can resist oil erosion and has enough durability at a certain temperature; It is easy to clean and replace filter materials
When installing and using the oil filter, keep it clean
The filter screen shall not be damaged, and the filter element with holes shall not be used
During installation, it shall be noted that the oil inlet and outlet shall not be interchanged
Generally, the oil enters from the outside of the filter element and exits from the middle
The filter element shall be replaced after the running in test run of the hydraulic drawworks
In the future, the filter element shall be replaced every 1000 ~ 2000 hours of operation
