How to maintain water well drilling rig?

No matter which model of water well drilling rig is used for a long time, it will produce natural wear and looseness. Poor working environment is an important factor to aggravate wear. In order to maintain the good performance of the well drilling rig, reduce the wear of parts and prolong the service life, Sinovogroup reminds you that you must do a good job in the maintenance of the well drilling rig.

1. The main contents of water well drilling rig maintenance are: cleaning, inspection, fastening, adjustment, lubrication, anti-corrosion and replacement.

(1) Cleaning of water well drilling rig

Remove the oil and dust on the machine and keep the appearance clean; At the same time, clean or replace the engine oil filter and hydraulic oil filter regularly.

(2) Inspection of water well drilling rig

Conduct routine viewing, listening, touching and trial operation before, during and after the operation of water well drilling rig (main engine) to judge whether each part works normally.

(3) Fastening of water well drilling rig

Vibration occurs during the operation of water well drilling rig. Make the connecting bolts and pins loose, or even twist and break. Once the connection is loose, it must be tightened in time.

(4) Adjustment of water well drilling rig

The relevant fitting clearance of various parts of the water well drilling rig shall be adjusted and repaired in time to ensure its flexibility and reliability, such as the tension of the crawler, the tension of the feed chain, etc.

(5) Lubrication

According to the requirements of each lubrication point of the water well drilling rig, the lubricating oil shall be filled and replaced on time to reduce the running friction of the parts.

(6) Anticorrosion

The water well drilling rig shall be waterproof, acid proof, moisture-proof and fireproof to prevent corrosion of all parts of the machine.

(7) Replace

The vulnerable parts of the water well drilling rig, such as the friction block of the power head trolley, the paper filter element of the air filter, O-ring, rubber hose and other vulnerable parts, shall be replaced in case of loss of effect.

2. Types of water well drilling rig maintenance

The maintenance of water well drilling machine is divided into routine maintenance, regular maintenance and specific maintenance:

(1) Routine maintenance refers to the maintenance before, during and after work, which is mainly used for external cleaning, inspection and fastening;

(2) Regular maintenance is divided into one, two and three levels of maintenance to adjust, lubricate, prevent corrosion or local restorative repair;

(3) Specific maintenance – it is non recurrent maintenance, which is jointly completed by the water well drilling machine driver and professional maintenance personnel, such as running in period maintenance, seasonal maintenance, sealing maintenance, maintenance as appropriate and replacement of vulnerable parts.

3. Contents of daily inspection for water well drilling rig maintenance

1). Daily cleaning

The operator shall always keep the appearance of the water well drilling rig clean, and timely clean the rock or geotechnical fragments, dirty oil, cement or mud. After each shift, the operator must clean the outside of the well drilling rig. Pay special attention to timely clean the rock and soil fragments, dirty oil, cement or mud on the following parts: power head base, power head, propulsion system, transmission chain, fixture, drill frame hinge joint, drill pipe, drill bit, auger, walking frame, etc.

2). Troubleshooting of oil leakage

(1) Check whether there is leakage at the joints of pump, motor, multi-way valve, valve body, rubber hose and flange;

(2) Check whether the engine oil leaks;

(3) Check the pipeline for leakage;

(4) Check the oil, gas and water pipelines of the engine for leakage.

3). Electrical circuit inspection

(1) Regularly check whether there is water and oil in the connector connected with the harness, and keep it clean;

(2) Check whether the connectors and nuts at lights, sensors, horns, switches, etc. are fastened and reliable;

(3) Check the harness for short circuit, disconnection and damage, and keep the harness intact;

(4) Check whether the wiring in the electric control cabinet is loose and keep the wiring firm.

4). Oil level and water level inspection

(1) Check the lubricating oil, fuel oil and hydraulic oil of the whole machine, and add new oil to the specified oil scale according to the regulations;

(2) Check the water level of the combined radiator and add it to the use requirements as required.
