Works hydraulic cylinder honing machine Hone Tube sizing there are two ways: (1) constant pressure feed, two quantitative feed. Constant pressure hydraulic feed generally have achieved, but also useful for the spring. Quantitative feed is usually achieved by a servo motor, stepper motor or some other intermittent mechanism, manual feed mode can also be regarded as a quantitative feed. You may belong to put constant pressure hydraulic feed, honing head can not shrink probably sizing cylinder does not move, try to improve the hydraulic system pressure. Or honing head stuck, remove the check. In addition, you are honing machine used in the transformation, the structure may be different, the leaflet, the principle and structure analysis. Vector frequency characteristics of the application in the honing machine series is a new generation of high-performance vector inverter, has the following features: Using the latest high-speed motor control ASIC DSP, ensuring rapid response vector control hardware circuit modular design to ensure stable and efficient operation of the circuit design European car design concept combines smooth lines, beautiful appearance.

When the machine fails we do not panic, first look at what the  Hone Tube   reason for this failure is that ? Then check the reason it should start from what place? Following on from honing tube manufacturers about the reason for us to sort out this aspect Symptoms and Causes
Find the cause of the fault from the following three points in the maintenance and improvement of the system :
( 1 ) Check the boom cylinder leakage situation . The easiest way is to move the arm rises , to see if there is significant free fall . If you disassemble the fuel tank to check the whereabouts of obvious , such as the ring is worn and should be replaced. ( 2 ) Check the control valve . First cleaning valve, check the valve for wear , such as wear and tear should be replaced. If there is still no change in the safety valve is installed , and then check the control valve spool wear, the gap is generally limits the use of 0.06mm, badly worn should be replaced. ( 3 ) measuring the pressure of the hydraulic pump . If the pressure is low , then make adjustments , plus the pressure is still not tune up , then pump heavy wear . In general , the main reason causing the boom can not raise the load as :. A pump heavy wear . At low speed pump leak serious ; during high-speed operation , the pump pressure increased slightly , but the wear and the vent pump volumetric efficiency decreased significantly , it is difficult to reach the rated pressure. Long working hours and increased pump wear , temperature rise , resulting hydraulic components and seals wear aging , damage , loss of sealing ability , hydraulic oil deterioration, leading to failure. b. hydraulic component selection unreasonable. Specifications for the boom cylinder 70/ 40 non-standard series , the seal member is also non-standard , high manufacturing cost, and replacement of seals
Inconvenience. Boom cylinder bore small , is bound to make the system set pressure is high. c. Hydraulic system design is unreasonable . Control valves and hydraulic steering gear is a single pump series , the safety valve set pressure of 16MPa, while the rated working pressure of the hydraulic pump
Li also 16MPa. Pump often work at full load or prolonged overload ( high pressure ) conditions , and the system has a hydraulic shocks, oil changes for long periods , hydraulic oil contamination , increased pump wear, so the pump casing burst ( after have been found such failure ) . Everyone can be repaired in accordance with the above guidelines encountered hydraulic pump failure .
