Product Description
Excavator spare parts Pc-800 Hydraulic Pump 708-2l-00760
The main pump for the wheel excavator with the pilot pump will also have a pilot oil filter, and the pilot filter must be replaced. This is because the pilot pumps are generally in the form of gear pumps. Although the gear meshes are lubricated by hydraulic oil, they are also worn out, and some of the iron scraps fall off and enter the hydraulic system. If the pilot pump filter element is not replaced in time and the pilot filter element is clogged, the hydraulic oil will continue to provide the pilot oil flow through the bypass oil circuit. At this time, the pilot operation valve may be stuck.We can also supply the wheel excavator ,crawler excavator ,construction machinery attachment , pipelayer .
The whole car is slow and weak.
1. The hydraulic pump output is insufficient, and the service diagnostic system can be tested for relevant pressure; 2. The insufficient pilot pressure causes insufficient pressure to open the spool, resulting in insufficient flow and slow operation; 3. Hydraulic return filter and oil filter are blocked phenomenon.
Walking weakness
1. The hydraulic pump and its control system are faulty. It is necessary to test whether the P1 and P2 pump pressures are within the normal range; 2. The pilot oil circuit pressure is abnormal; 3. The travel system control valve spool and valve seat wear; 4. The travel motor The pressure is abnormal; 5. The spool of the travel port overflow valve is blocked, and the spool is issued.
Rotational weakness
1. Circuit reason: Check whether the relevant circuit such as the rotation sensor is loose, and the voltage resistance value of each joint. 2. Hydraulic reasons: the internal components of the rotary pump of the excavator are worn, the wearer of the excavator is worn, the control valve of the hydraulic pump is broken, the pressure value of the left and right rotation of the excavator is high or low, the internal pressure of the rotary pump is released, and the rotary motor of the excavator is sealed. The failure seal is not well drained, the overflow is not properly adjusted, and the swing motor is overloaded. Lifting big / small arm weakness 1. Large / small arm arm oil circuit is blocked, oil supply is not smooth; hydraulic pump suction port filter is blocked, oil pump can not suck oil; 2. large / small arm cylinder internal leakage; 3. large / Small arm valve core is issued, resulting in poor oil path; 4. The overflow valve has a blockage.
Bulldozer spare parts ,loader spare parts , excavator spare parts we are also have the good price advantage .
1. Multi-way valve upper arm oil valve spool wear; 2. Bucket cylinder assembly wear/damage; 3. Bucket spool valve core stuck/wear; 4. Bucket regenerative circuit valve, Check Valve back The spring force of the spring is too weak.
