Français- Hydraulic Gear Pumps
Hydraulic gear pumps are mainly include high pressure single gear pump, multi gear pump,compound gear pump,bidirectional aluminum alloy gear motor,cast iron gear motor and other special customized products.The max pressure of HCHC gear oil pump can reach 31.5 MPa, the service speed of high speed gear pump can reach 15000rpm and the displacement range of the pump is from 0.25mL/r to 200mL/r. According to the market demand,HCHC also developed low noise gear pump,high speed gear pump,large displacement pump etc. pump widely used in construction machinery,industrial vehicles(forklifts),special purpose vehicles,modern agricultural machinery,ships,wind power lubrication systems,aerospace and traditional machine tool industries,etc.
HCHC hydraulic gear motors mainly include high speed(over 800rpm) external gearing motor and can be divided into two kinds,such as aluminum alloy motor and cast iron motor.The nominal displacement of aluminum alloy gear motor ranges from 1.6mL/r to 100mL/r,and that of cast iron gear motor ranges from 2.5mL/r to 200mLlr.The max pressure can reach 28Mpa and the max rotation can be 7000rpm.Small and medium nominal displacement motor could be combined with valve parts such as safety valve,check valve and magnetic valve,etc.Two way motor can realize internal leakage and external leakage scheme to meet the specific needs of various users.
HCHC hydraulic gear pumps and motors are mainly classified two kinds: aluminum alloy and cast iron materials by material classification.Aluminum alloy products have 8 series,including1.25、1.75、2、3、4、5、5.5、6module,hundreds of varieties,thousands of specifications for choosing;Cast iron gear pumps have 6 series from DP4 to DP10 and dozens of varieties and can realize the combination of different varieties to form two sections,three sections,four sections and more sections gear pump;The inlet and outlet flange,shaft extension and seam allowance installing form comply with national standard and SAE standard.Special installation forms can be customized.
With professional,automatic modern gear pump and motor production workshop,the annual output of all kinds of products can reach more than 800,000 pieces.HCHC has nearly 200 skilled workers with more than 10 years working experience,many processing centers and a large number of special equipment's,CNC equipment to meet the needs of the market diversification of flexible production lines. High precision measuring instruments,experienced professional quality inspection team ensure the reliability of product quality.The core components of gear pump products,gear processing basically realizes the CNC production of roiling,shaving,inserting,quilting and grinding processes ensure the processing capacity and quality level of the core components of gear pump products.
A professional design team with rich working experience and profound technical skills insures the continuous upgrading of products and the emergence of new products in an endless stream.Numerous invention patents,such as low noise gear pump,large oil cavity gear pump,anti-offset positioning pin gear pump,multi-external gear pump,fully balanced hydraulic floating side plate,high strength aluminum alloy material,high performance wear resistant powder metallurgy material and many other invention patents make our gear pump and motor products have very high performance.
Clean and tidy assembly site,advanced performance test bench,high cleanliness(nass level 9+)cleaning bench, low noise testing room and other professional performance testing equipment ensure that the market with high quality hydraulic components.
