Outbreak of war production, excavator parts small make up teach you fast locking point of failure!

Now policy power enterprises at all levels and production, the resulting excavator also want to busy, holiday park for so long, hard to avoid can produce all kinds of fault, so, how to get rid of the excavators of slow? small make up teach you fast locking point of failure! Excavator slow mainly displays in three aspects: single action is slow, the whole car slow, slow heat engine movements. We would make a concrete analysis these three questions:

a. Single action is slow, slow single action implemented including walking, lift arm, turned and scoop the rotation operation. If walking is operating, inversion, carry large forearm, recover the scoop, such as when a single homework, speed is slow. May be the following reasons: excavator attachments related components of the overflow valve pressure too low ( Need to test) ; Pump, low pressure sensor, multi-channel valve fault; Related electromagnetic valve failure, valve core hairpin. 1. Component failures. : action widget itself to accept bad information or poor contact in the process of implementation, overflow valve pressure too low (or related components itself The pressure of the relief valve can control the overall, more than the overflow valve can withstand the pressure, the hydraulic system will overflow) , tractor driver can tap parts to see whether there is a screw loose or the pressure test, and maintenance of processing. 2. The conduction process of failure. The command fails, in the process of conduction block command signal transmission, key so you can check the pump, low pressure sensor and multi-way valve to see if a failure. ( Timely repair or replacement excavator attachments) 3. Operation center of failure. The excavator instructions issued center is broken, leaving no signal, this kind of situation is more complex, generally also need professional maintenance instruction, you dig a machinist can examine related electromagnetic valve failure, whether the valve core hairpin.

2. The whole vehicle slow 1. The hydraulic system. Hydraulic system is one of the power system of excavator, if excavator vehicle slowly, should check the hydraulic system for maintenance on time, and whether the hydraulic oil change regularly, expired hydraulic oil will not only affect the effect of the excavator performance, more corrosion wall of hydraulic excavator. At the same time should also check the hydraulic oil and oil return filter blocking phenomenon, if there is congestion, you should clean up the oil, serious when excavator parts should be changed. 2. Engine power is too low. As well as the hydraulic system, the engine is also one of the dynamic system of excavator, low engine power will lead to low output power, resulting in excavator suppress car, slow excavator vehicle moves. The engine output power is too low, underpowered please combined with the data analysis of the output of the engine condition, all cylinder is able to work at the same time; Check the presence of black smoke appeared, if worn nozzle, can also cause engine power down. 3. Hydraulic pump, hydraulic pump output is insufficient, this belongs to the conduction of the hydraulic system failure, one of the tractor driver can access to the service diagnosis system for related pressure test, whether because of hydraulic pump in excavator slow conduction. Pilot pressure is insufficient cause open valve core, causing traffic is insufficient, lead to drivers slow. 4. Circuit related issues. Excavator CPU, high and low pressure sensors, solenoid valve and line fault.

3. Cold machine is normal, heat engine slow 1. Check the oil. Check whether the use of fuel is accord with the requirement of the excavator, if fuel for too long there is no change in oil is too dirty, should be replaced immediately; Check the oil filter for copper scrap, causing the main pump wear and tear, if wear be disassembled to view. 2. Filter clogging. Oil and filter blocking causes so check to see the guide filter, oil filter, oil suction filter is blocked filter blockage, need to clean up blocking material, serious when need to change filter ( ) 。 3. Main pump control unit. Main pump control device on the piston of get muddy, excavator daily work is dealing with soil, most of the time so the piston become muddy also unavoidable, but the pistons jams can reduce main pump of pump pressure and power output decreases, the excavator slow. Therefore excavator parts daily maintenance, also should pay attention to clean up all parts of the mud. 【 Excavator accessories manufacturers] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent the views or responsibility for their authenticity.
