Part Name:Proper Displacement Injection Molding Five Star Motor
Especially used in petroleum and coal mining, plastic machinery
Can also be used in Hydraulic transmission of mining, construction,
engineering machinery, lifting and transportation equipment,
metallurgy, marine machinery, geological drilling and other machinery.
NIM series low-speed and high-torque hydraulic motors adopt
star-shaped arrangement of plunger and crank connecting rod
mechanism to convert hydraulic energy into rotating mechanical energy with the help of oil distribution
machinery. They have various advantages such as low noise, large
starting torque, low speed stability, high efficiency, long life, variable speed range, compacted
structure and other characteristics. Can be applied in sol motor of
injection molding machine, 5-star oil motor of mine, marine hydraulic motor.
Main features:
1. This series of hydraulic motors is designed as a static pressure
balance structure between connecting rod and crankshaft motion, can
get good lubrication during friction.
2. As the decrease of heat and friction loss, mechanical and
starting efficiency of the motor are improved, which increases the
working pressure.
3. The crankshaft of this series adopts split structure, which
improves the service life of the crankshaft.
4. The key components of this series are made of special materials
and heat treatment process, which effectively improves the service
life of the motors.
We can design, manufacture and transform various standard,
non-standard hydraulic system, production standard, non-standard
cylinder, integrated circuit board and so on.
