L6V107HD1DFZ20700 used in Xugong (heavy) truck crane special instructions before 1 product operation, must ensure that each pipeline filled with oil pumps, motors and systems, otherwise it will cause damage to the product due to poor lubrication; 2. Host hydraulic system fluid cleanliness is not below the ISO4406 19/16 level, otherwise it will cause product failure manipulation, or even damage; 3. tank must be properly set up and the system cooler pump maintenance, ensure that the system is not up to the oil temperature exceed 80 ℃. Letter user: To extend the life of the pump, please user to: (1) shall be kept for any occasion cleanliness of hydraulic oil; (2) periodic replacement of the hydraulic oil (working 1000-3000 hours, or six) hydraulic pump are rely on the principle of changes to the volume of the sealing work, it is commonly referred to as a positive displacement pump plunger mounted in the cylinder block 2 to form a sealed volume 3 a, the plunger under the action of the spring 4 is always pressed against the eccentric 1 on. A prime mover driven eccentric rotation of the plunger 2 reciprocates, so that the size of a sealed volume generation cycle [2] of alternates. When a small to large, from the partial vacuum is formed, so that the oil tank at atmospheric pressure pump repair action, the suction tube to open the top one-way valve 6 into the oil chamber a suction is achieved; on the contrary, when a hour from big, a suction chamber full of oil will top the one-way valve 5 into open systems achieve oil pressure. Such pump to the prime mover input mechanical energy into fluid pressure energy, the prime mover driven eccentric continues to rotate, the pump will continue to suction and pressure oil.
