How to repair or replace a damaged component of the hydraulic anchor drilling truck used in coal mines（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will introduce how to repair or replace a damaged component of the hydraulic anchor drilling truck used in coal mines. If a component of the hydraulic anchor drilling truck used in coal mines is damaged, the repair or replacement methods are as follows:

1、 Repair method

1. Maintenance of hydraulic system faults:
2. Unstable or low pressure: Check whether the control valve is faulty, and repair or replace it if there is a problem; Clean the blockages in the pipeline to ensure that there is no leakage of hydraulic oil and that the oil level is sufficient. If necessary, add or replace hydraulic oil.
3. Motor malfunction: If the pressure regulating valve is not adjusted properly, it needs to be readjusted; Insufficient pressure in the hydraulic pump station, the pump station needs to be inspected and repaired; The hydraulic motor is severely worn and should be replaced; If the oil filter is clogged, clean or replace the oil filter.
4. Oil cylinder malfunction: The sealing ring is damaged and needs to be replaced; The oil inlet pipe is blocked and needs to be cleaned; The hydraulic system pressure is insufficient, and the solution to the pressure problem mentioned above should be followed.
5. Maintenance of electrical system faults:
6. Difficulty starting the motor: Check the power supply voltage. If there is excessive fluctuation, stabilize the voltage; Control circuit short circuit, check the short circuit point and repair it; Replace the switch if it is damaged.
7. Control system failure: Also check the control circuit and switches, repair or replace the faulty components.
8. Maintenance of power system malfunction: Engine overheating: Check the cooling system and repair the faulty components.
9. Other fault repairs:
10. The drilling rig does not spray water or intermittently sprays water: if the water valve is blocked or the sealing ring is damaged, the water valve and sealing ring need to be cleaned or replaced; Adjust the water pressure and air pressure if the water pressure is too high or the air pressure is too low; The control gas cannot reach the water valve. Check the gas circuit and repair it.
11. Unable to turn off the water: The water valve is stuck in the open position. Remove the water valve for inspection and repair; The water switch valve is stuck, clean or replace the switch valve; Control the continuous action of the gas to water valve and check the gas path; Sleeve and journal wear, replace worn parts.

2、 Replacement method

1. Determine the parts that need to be replaced: Haoyun Heavy Industry determines the damaged parts based on the fault symptoms and inspection results.
2. Prepare to replace parts: Purchase new parts with the same specifications and models as the original parts.
3. Component replacement:
4. Replacement of hydraulic system components: If replacing hydraulic oil pipes, first close the relevant valves, release pressure, disassemble the old oil pipes, install new oil pipes, and ensure that the connections are firm and leak free.
5. Replacement of electrical system components: When Haoyun Heavy Industry replaces switches and other components, first cut off the power, remove old components, install new components, and ensure correct wiring.
6. Replacement of power system components: To replace large components such as the engine, professional personnel are required to follow the steps in the maintenance manual.
7. Replacement of other components: such as replacing drill bits, drill rods, etc., simply disassemble the old components and install the new ones.
8. Test Run: After replacing the components, conduct a test run to check if the equipment has returned to normal. If there are still issues, further inspection and repair are required.
