Another to portray the special effects or patterns on the leather so that the finished product even more fine and creative

Hydraulic roller Fault
Roller is composed mainly by walking system, vibration and steering systems, and its design according to the layout of different products from different manufacturers design concept will be different, but the same principle. Here some trouble walking and vibration often appear to give analysis and judgment in order for the exchange.
First, the walking system is divided into two, a single drive type, a dual-drive type. But the two walking systems in the course of the main failure of weakness (or after working long hours to walk along with the temperature rise, weakness), or a sudden lack of walking, only the slow no fast and other reasons for walking in here We analyzed separately.
One, suddenly no walking required in the following aspects to judge
First, check the hydraulic fitting tank oil bit is normal, as normal, measuring walking pump up the oil pressure, depending on the use of the hydraulic pump, set up the oil pressure values ??will be different to its normal pressure is 18-24KG . Up the oil can be classified according to the system design, remote fill oil and oil pump comes with fill pump up the oil. Up the oil pressure relief valve is normal under the premise, such as remote up the oil pressure value is zero or fill low oil pressure value, then the remote fill pump damage; such as comes to fill the pump to fill the oil pressure value is zero or very low, To consider the pump power input damage or charge pump damage.
If the normal pressure value of more than make up the oil the need to pump high pressure oil port output side closed die, while the output termination 600KG of high voltage meter to measure the walking state of high pressure reading, the pressure range between 350-420KG, such as pressure value zero, then the oil pump control mechanism damage; So when the pressure is normal, it is damage to the drive motor.
2 unable to walk unable to walk or prolonged temperature rise, and its judgment in the method similar to the same as above.
First up the oil pressure measurement, such as normal put the oil pump high-pressure port side close to death, while increasing the throttle in a walking state measurement of high pressure oil port and fill the oil pressure, the high-pressure measurement values ??should be between 350-420KG, and up the oil pressure is 18-24KG within. Such as pressure values ??is not normal then pump damage; So when the pressure is normal, one by one according to the number of walking motor connected to the motor oil, the system pressure drop, the motor is normal, on the contrary, the motor damage.
Walking speed change speed change mechanism of its roller divided into two types, a variable speed by a variable motor, the other is to rely on quantitative motor and gearbox to achieve variable speed.
(1) variable motor agencies can not be variable-speed variable motor displacement control mechanism can not be normally open or failure, we must first check the travel speed control switch is good, variable-speed solenoid valve is normal, and the measuring circuit in the solenoid valve parts is smooth to ensure that the solenoid valve can be smoothly opened and connected to variable speed control circuit to ensure its normal pressure (the pressure to make up the oil pressure). If the above is good, the motor is damaged.
(2) quantitative motor gearbox institutions can not be variable speed, its judgment is relatively simple, such as normal quantitative motor working pressure, gearbox damaged, recovery can be achieved variable speed.
Second, the vibration system failure analysis of its failures mainly to vibration or vibration of weakness (often enough, the vehicle resonance), its system in the form of the pump motor is divided into: a system composed of columns of the gear pump / gear motor  start valve piston pump  piston motor system.

Gear pump, first check the tank oil level is normal, then check start valve, start-up valve in two ways, a mechanical PULL control overflow stop valve, another electromagnetic control overflow stop valve. PULL control overflow check the mechanical stop valve, depending on the control PULL is connected properly, relief valve and the valve body whether there are impurities, the formation of the cassette phenomenon. For the control should be checked by the electromagnetic vibration switch and the circuit is normal, the electromagnet is working properly, the valve body spool with relief valve is normal. Above check from the vibration valve, the motor inlet pipe closed die, closed die before the pipeline, the installation of the pressure measurement device, the gauge measuring range is 0-400KG, open the vibration, then measured have the pressure peak (according to the rated working pressure of the pump) does not exceed the pump rated pressure. Pressure is normal, connect the motor to open the vibration, such as the motor is normal, the pressure of open vibration peak pressure should be measured before, and with the increase of vibration wheel speed, the pressure drop (pressure according to the job site will be different but remained stable), the vehicle no resonance. So when the measured pressure reach the peak, and the wheel vibration frequency less than the vehicle resonance motor damage, so when the wheel vibration does not work, compared to motor and wheel vibration eccentric shaft with sleeve damage; in the measured when the peak does not drop, vibration wheel to skiving machine, compared with vibratory drum eccentric shaft killed.

Piston pump / motor vibration system, and its judgment that the system failure is similar to walking with the judge. First, you should check whether it is normal oil tank, pump oil into the system, the filter is clogged, above normal, installed in vibration pump up the oil pressure taps range of 0-40KG gauge, measure up the oil pressure, the pressure at this time The value should be between 18-24KG, such as pressure is low or no pressure, compared to the charge pump is damaged or vibration pump power input. Pressure is normal, check the vibration pump solenoid valve is intact, while the vibration pump two high-pressure port closed die, and install a pressure gauge 0-600KG, turn on the vibration, measured by high-pressure peak pressure of 350-420KG, and up the oil pressure dropped to normal. Connected motor oil, and then repeat the measurement of peak pressure in the vibration is turned on and up the oil pressure, the peak pressure transient peak, and decline with the vibration of the wheel speed increase pressure and maintain stability, make up the oil pressure is not reduced to normal. So, the measured vibration pressure of less than peak, and up the oil pressure drops, vehicle resonance is motor damage, such vibration wheel does not move, compared to motor and wheel vibration eccentric shaft with sleeve damage. So, the measured vibration pressure peak, and the pressure did not fall, the vibration of the whe
