In the seventies&commaHilead manufactured the initial CY14-1B serise piston pump&periodAfter thousand instances demo production experiments&commawe broke via the CY massive specification pump’s accelerating question for the very first time in domestic&commathe rotational pace enhanced from one thousand rpm to 1500 rpm&commaand attain to 2200 rpm&time period
In 1998&commaHilead produced the initial Q series low sounds axial piston pump in the domestic&commacompared with the regular piston pump&commathe sound decreased 4 Db&commathe radial direction size decreased 60mm&commathe heigh has been shortened 47mm&commathe solitary set bodyweight reduced 10kg&commaespecially&commaQ100 and Q125 pump loaded the domestic hole&periodEven nowdays&commaHilead is a chief of CY series piston pump&time period

Advantages&colon
one&period Decide on the higher-precision needle bearing with holder to change the previous brief cylindrical roller bearing&time period So lower down the sound of the pump and reduce the external proportions and fat&period
two&time period The oil absorption channel spot of Q&astCY14-1Bk is elevated by forty&percnt&interval So the self-absorption capacity and peak speed of the pump are lifted as well&period of time And the sounds of the pump is reduced&interval
three&interval Boost the framework of the valve plate&period of time So elevate the oil absorption capability and minimize the noise&time period
four&period Enhance the framework of the central spring&period of time Lower down the spring pressure&period of time
5&time period Boost the framework of piston&time period Elevate the pressure of pulling or dragging by twenty&percnt&period of time
6&interval Use the precision casting housing which seems much better&time period Make the interior wall of the channel fantastic and specific&period of time
