Formerly known as Ningbo Hydraulic Motor Plant,
our company is one of the specially appointed 220 national ¡°Revival
Basic Machinery and basic parts¡± manufacturers approved by the
State Planning Commission and Mechanical Ministry and one of
the specially appointed manufacturers of the state for producing
low-speed big torsion hydraulic motors. In 1987, we were appraised
as the provincial advanced enterprise. In 1997, we were appraised
as national high and new technology enterprise and listed as
the national demonstrative enterprise for CAD project application.
In 1999, we passed ISO9002 quality system certification. The
radial ball plug type low-speed big torsion hydraulic motors
developed by ourselves have won the 2nd prize of scientific
research fruits at Zhengjiang Science Congress. In 1996, we
actively carried out trail-produce of ZJM series hydraulic motors
on the basis of the world up-to-date technology from which we
benefited. And this was listed as one of projects of Torch Plan
by the State Science Commission of the year 1998. We have set
up city-level hydraulic technology center, which can undertake
design and trail-produce for hydraulic system and complete set
of hydraulic equipment. The products listed in this catalog
are all put into production. Should clients have additional
requirements regarding the installation size and technical parameter,
we can redesign to meet their demands under general circumstances.
QJM hydraulic motors are applied to various kinds of oil pumps,
valves and hydraulic accessories to form a complete set of hydraulic
transmission device. As many solutions are taken into consideration
in the design, it may fit for various operation modes of machine.
This kinds of motor features such advantages as light, compact,
large range of speed, stepped variable, automatic shut-off of
mechanical brake, fine low-speed stability, reliable performance,
shock0resistance, high efficiency, and long service life etc.
Presently, the motors are widely applied in construction engineering,
hoisting & transportation, metallurgic and heavy industry,
oil, coal mine, vessel, machine tool, light industry and injection
molding, geologic prospecting and other departments for directly
driving crawler belts, rail wheels, various turning and hoisting
mechanisms, prospecting drills, belt conveyance, material agitating,
road cutting vessel propulsion, plastic premolding institutions.
