The normal operation of the hydraulic system will be affected immediately if the hydraulic oil pump fails. Noise is often a fault of hydraulic oil pump, but how to detect and solve it?
Abnormal sound of hydraulic oil pump in boom pump truck is usually caused by the following reasons:
1, the filter device or suction pipe parts are blocked or according to the area is small this time we have to do is to clean up the day pump filter element or suction pipe, replace the suitable filter device or suction pipe.
1, the filter device or suction pipe parts are blocked or according to the area is small this time we have to do is to clean up the day pump filter element or suction pipe, replace the suitable filter device or suction pipe.
2. The fuel tank exhaust port of the concrete pump truck is blocked, which requires us to clean the vent.
3. When the oil suction part is too high or the fuel tank oil level is too low, we need to reduce the assembly aspect ratio of the hydraulic pump or refuel to the oil level line.
4. The sealing of hydraulic oil pump or suction tubing is not tight at this time, we should check the sealing of the joint and the joint surface, and tighten.
5, suction bubbles in the newly installed oil pump is more common, we should do a good job of no-load operation, solve the air; The suction pipe and the return pipe are separated from a certain distance, so that the return pipe mouth is inserted into a certain depth under the oil surface, and the return pipe can not be placed on the oil surface.
6. The viscosity of oil is too high. We check the oil quality and choose the viscosity of oil according to the requirements.
7. The suction cavity channel of the hydraulic oil pump of the concrete pump truck is not free. At this time, we should remove the pump and do a good job of cleaning and checking.
8, the bearing or internal parts of the hydraulic oil pump wear obviously. At this point we have to disassemble the pump to repair or replace it.
Above is some about the boom pump truck hydraulic oil pump several abnormal phenomena and emergency solutions, hope to have certain help to the application of concrete friends pump truck.
Zhejiang Xinrui Heavy Industry independent design and development of concrete pump truck, boom pump truck, cloth machine, stable and reliable, flexible mobile, environmental protection and energy saving, chassis, power, electronic control, hydraulic, pumping system scientific standard collocation, boom telescopic and convenient, leg covers an area of small space, the vehicle is convenient to move, according to the strong. Applicable to new rural planning, urbanization development, beam making field, bridge construction site construction. Using boom buffer technology, timeliness under the condition of high output, the rod vibration is small, microtubule stability; It has the function of remote engine flameout, which can start or stop the engine operation according to the requirement of working condition. The remote control has the function of speed ratio adjustment, can adjust the engine speed in real time according to the actual working condition; The displacement adjustment function of the remote control can adjust the concrete pumping volume according to the actual working condition.
