In preparation for well drilling rig before the start. Our company is a professional manufacturer producing well drilling rig, location, perfect production equipment, strong technical force, detection means perfect, reliable product quality, service warm and thoughtful, trustworthy, won the majority of customers praise, Here I will introduce water well drilling rig under examination and preparation before starting. 1. Check all rig components, the installation is stable and reliable, rope and coupling is in good condition, and remove dust from the rig, mud, etc. thereof. 2. Check the operation of the rig is flexible and easy to use accessories, positioning Elastic, each V-belt tension is appropriate (especially for main and auxiliary hoist brake friction clutches and two handles), the need to add and adjust if necessary. 3. Check the power machine and mud pump. Steering should be correct. 4. In accordance with the lubrication specification and illustrated lubricate all parts rig. 5. Press provisions to the gearbox, wheel, turbo tank oiling main hoist. 6. diesel engine clutch is disengaged, mud clutch, empty plate moving sheave feed handwheel observe gearbox, main hoist universal shaft, if there is touch dead killed turntable place and, if it should be adjusted. 7. stirring mud. To ensure the quality of drilling, drilling efficiency, front opening to prepare a certain quality and a certain amount of mud, usually in the Quaternary stratigraphy hole using 600mm wellhead protection tube mud hole need not less than 4m3, viscosity at 10 ~ 20Pa .s between. 8. rig commissioning. Drill rig ministries examination is completed, it should be load test run. Ministries observed in normal operation, before the official start of drilling. Rig Hydraulic System Troubleshooting performance rig hydraulic system for the implementation of components ------ hydraulic cylinders, hydraulic motors power shortage; if rigs all hydraulic actuators are not strong enough, the main consideration systemic problems, first hydraulic pump pressure or flow whether the requirements of well drilling, more direct way is to use a pressure gauge to test the system; furthermore consider checking system relief valve leaks. Relief valve seal replacement lax relief, so the simplest operation, the lowest price; hydraulic pressure is insufficient to replace the pump, relief valve and pump are generally non-serviceable parts, should be replaced as a whole; if it is one action strong enough rig, it is a problem with the actuator, hydraulic cylinder ----- consider unloading the fuel tank seal is broken or damaged hydraulic lock; in this case replace the hydraulic lock or replace cylinder seals.
