A kind of special vehicle widely used in the construction of fully automatic mixer truck. Its main components are the chassis and upper tank. During the driving process of the vehicle, the tank rotates at a constant speed, and the rotation of the tank is realized by the hydraulic system. The hydraulic motor is an important component of the hydraulic system. Because of its high frequency of use and poor use environment, some failures occasionally occur, What are the common faults of hydraulic motor?
Fault 1: Low output speed and torque due to insufficient fuel supply
Analysis of causes and solutions: the filter at the oil suction port of the oil supply hydraulic pump is blocked, and the oil filter can be cleaned at this time; If the oil drill is too large, the proper oil can be replaced; If the axial or radial clearance is too large, grind the stator or other relevant parts to make the axial clearance meet the requirements.
Fault 2: Improper power or speed of prime mover of hydraulic motor leads to low output speed and torque
Analysis of causes and solutions: the power of the prime mover does not match. At this time, the prime mover needs to be replaced to match the power of the hydraulic pump; If the speed of prime mover is lower than the rated speed, prime mover meeting the requirements can be selected.
Fault 3: All connections are not tightly sealed and air is mixed
Solution: Check and tighten the joints to improve the sealing performance.
Fault 4: The working medium is polluted and the internal channel of the hydraulic motor is blocked
Solution: Disassemble, carefully clean and replace the clean working medium.
Fault 5: The valve plate and blade are worn and the internal leakage is large
Solution: repair or replace relevant parts.
Fault 6: The one-way valve in the hydraulic system is poorly sealed
Solution: Repair the check valve seat or replace the relevant parts to make the valve seat closely fit with the steel ball.
Fault 7: overflow valve in hydraulic system fails
Solution: repair or replace the relief valve.
The above are the common failures and causes of the hydraulic motor of the fully automatic mixer, but these are only part of the failures. You must master some repair skills in the process of using the vehicle, so that you will not "lose the chain" at the critical moment. Follow us http://www.zkzdsljbc.com , learn more!
