Nowadays, the application range of the hydraulic power unit is more and more widely, in practical applications, the working performance of hydraulic power units often directly affect the running state of the whole system. So during the period of using, we need to take action to ensure it is flexible in operation.
As a user, for various abnormal problem encountered during use, should be timely find out the problem reason is analyzed, and find out solutions. If it is found that the hydraulic power unit motor does not turn, for example, or the reverse, so need to check the line problem. If it is reversed, you will need to take transposition wire can solve.
Still have a kind of situation is more common, that is in the work of hydraulic power unit, the motor can be normal boot, but oil cylinder rose is not in place or not stop walking instability. Why is this case? Investigate its reason, can from six aspects to consider: 1, the hydraulic oil tank didn't add in place, according to the requirement to add oil to 30 to 50 mm position of oil outlet; 2, a gas cylinder or oil pipeline, the tubing will be removed after the mount; 3, reversing valve wire connection errors, caused by the reversing valve application does not meet function, oil returning from reversing valve, tank need to view the reversing valve connection is correct; 4, the pressure regulating valve regulating is too small, at this time should be adjustable, and then adjusted to a suitable pressure size; 5, reversing valve, or manual valve closed, remove the clean or replace. 6, gear pump oil outlet seal is damaged, remove the replacement of seals.
Also may encounter when unloading in hydraulic power unit, the oil cylinder no descent or instability. Don't answer at this time may be due to the electromagnetic valve is not normal, electricity or jump or voltage falls below, circuit shall be checked. Also may be due to the current time is too long or voltage is too high, cause overheating, electromagnet burn, should replace the solenoid valve.
In addition during the use of hydraulic power unit, also may have some other problems, such as electrical components or line break, damaged, replace the electrical components in a timely manner. Or a hydraulic power unit to work long hours, the oil temperature is high, noise big, oil cylinder does not work properly or out of control and package should be in time to stop work.
