"Hydraulic oil pump suction air noise change causes

1. Check the hydraulic oil pump suction tube and joint [whether the diameter is too small, whether the curved dead angle is too much: Inlet pipe recommendation flow rate o. 6-

1. 2 m / min should minimize the bend and the inner bore suddenly increased and suddenly narrowed, the inhalation vacuum should be at least 200 mmHg (mmHg = 133. 322Pa).

2, check the tank filter, whether it is blocked or specifications to choose too small to make too much traffic: the human oil filter network, replace more absorbed oil filter network, generally when the hydraulic oil pump flow is 2QL / min The oil filter, filtration accuracy should be selected from 100 purpose (oil oil oil).
