Why block machine hydraulic system not work, how to solve?

Fast Answer: Hydraulic valve blockage; oil pump broken; coupling problem (motor and oil pump not connection; motor rotation direction not correct, hydraulic oil problem.

Detail reason explains and solution:

1.     Check motor connection with oil pump rotation direction is correct or not. Oil pump has confirmed rotation direction, diesel engine block machine (WhatsApp: +86 15269722300) usually has no this problem, but electrical block machine often has this problem, because motor cables connection not correct location, motor rotation direction not same, so when block machine hydraulic system not work, check motor rotation first.

2.     Hydraulic oil problem: usually add 46# Anti-wear hydraulic oil, if you use very thick hydraulic oil, hydraulic system may also not work; if you add not enough hydraulic oil, hydraulic system still not work, usually add 70-80% full of block machine hydraulic station vol. (WhatsApp: +86 15269722300)

3.     Hydraulic valve blockage: Valve include proportional valve and directional valve. Automatic hydraulic block machine has proportional valve, if automatic work model, hydraulic system not work, but semi-automatic or manual work model, hydraulic system work, that means proportional valve blockage; If only directional valve blockage, only one block machine movements not work, other movements still work,

4.     Coupling problem: if oil pump rotation direction corrects, valves not blockage, check connection area of diesel engine/motor with oil pump. (WhatsApp: +86 15269722300) Maybe coupling broken or not connection well. Diesel engine connection with oil pump by loose pins (Loose pins are usually used in diesel engines to connect the oil pump. The loose pins are also designed to reduce the vibrations of the diesel engine and minimize damage to the oil pump.)

5.     Oil pump problem: if you use machine some time, suddenly hydraulic system not work, maybe oil pump broken, when it broken, you may hear not normal oil pump working noisy. (WhatsApp: +86 15269722300) Open oil pump, pumping blades inside the oil pump broken. It usually because of dust in hydraulic system. Maybe because long time not change oil or not clear hydraulic system when you get block machine.
