The high pressure hoses of the hydraulic system of the tractor often break during use. In operation, corresponding measures should be taken for prevention according to different reasons:
1. Due to the erroneous use of the "neutral" position for the arable land, the oil hole from the distributor to the upper and lower chambers of the fuel tank is closed. Because the farmland is affected by the unevenness of the ground, the agricultural implements undulate and force the pistons of the oil cylinders to move up and down. The pressure in the oil tubes rises sharply, and breaks when the pressure exceeds the pressure of the hose. Therefore, it is necessary to use the "floating" position for arable land, and the ploughing depth of the ploughs should be controlled and adjusted by the positioning clamps of the supporting wheels or cylinders.
2. When the ploughs are hung, the pressure of the plows increases due to the high speed driving on the uneven ground, which increases the pressure in the fuel tanks and the oil pipes. If the safety valve does not open, the high pressure hoses are forcibly broken. Therefore, it is advisable to use medium and low speeds when transferring the ploughs in the field. When walking long distances, you should close the positioning valve and close the lower chamber of the oil tank or use a special hook to suspend the plough. On the tractor.
3, dispenser automatic return mechanism disorders. After the lifting of the plow, it cannot automatically return to the “neutral†position. The safety valve cannot be opened and the high-pressure hose can be subjected to a large load for a long period of time. Therefore, it must be promptly eliminated and repaired. In operation, it must be done: When the plough is lifted, it should be promptly returned to the "neutral" position.
4. The pressure of the safety valve is improperly adjusted, and the pressure of the opening is too high to cause the oil pressure to increase and break the hose. Therefore, check and adjust the safety valve pressure in time.
5. Improper installation of high-pressure hoses, distortion, and severe bending, as well as wear or rust on the braid of the steel wire, reducing the pressure bearing capacity of the hose. So install the high pressure hose properly.
6, due to the use of high-pressure hose is too long and aging, cracking, reduced pressure capacity, should be promptly replaced.
7. Use the hydraulic output to control the dump truck. When the cylinder is raised to the highest point, the extended time is too long, resulting in the rupture of the high pressure hose.
