Well drilling rig has good mobility due to performance, compact structure, integrity, and other characteristics, production and operation of its complexity is evident. We already know how to prolong the life of the well drilling rig? But in everyday use well drilling rig in the process will inevitably be some fault cheaper drilling rigs, engineers Dragon Industry Machinery Co., Ltd. Shandong to find out more drilling rig seven common faults and solutions! Troubleshooting a well drilling rig, rig clutch slipping, mainly because of excessive wear or friction disc rupture or compression spring aging or broken, should overhaul rig friction plate; Troubleshooting two well drilling rig, drilling rig couplings fever, excessive wear elastic ring; The reason is that when the rig power machine with the clutch assembly, coaxial poor, the need to improve the assembly concentricity; Troubleshooting III drilling rig, rig skidding winch brake, mainly due to the inner surface of the brake band have cheap oil wells drilling rig, need to be cleared hold the inner brake surface; if no oil rig holding the barriers, to check the brake band and brake wheel gap, such as tightening too loose to be appropriate; Troubleshooting four well drilling rig, no oil or insufficient oil rig after pump start, first Noi check fuel tank is low or no oil, gas to oil well drilling rig bit lines such as common fault persists, To troubleshoot the filter is clogged, another rig, but also about the fuel tank vent is blocked, or suction fittings Loose intake and other factors; Troubleshooting five well drilling rig, rig pumps heat and wear, the pump should be repaired or replaced, the oil viscosity is too high or too low, we must strictly follow the instructions provided with oil; also check the rig pump gear, raise assembly precision; Troubleshooting six well drilling rig, hydraulic oil temperature is too high, or too little oil in the tank pump damage, to refuel or repair the pump; pump to a reasonable choice of work, according to the instructions recommended operating pressure; drilling rig seven common faults, rig hydraulic system pressure less expensive solar rigs, pressure regulators fatigue limit nut to adjust or replace the spring; if the control valve seat cone damaged or stuck, to remove the pressure regulator set of simple maintenance; what is rig? Rig is a mechanical device surface drill holes, can be used to a large field of wells, oil wells, gas well drilling equipment, or a single person can move small devices. Underground mines can be sampled, or production equipment for underground installations. Can therefore means trucks, trailers, mobile device on the track, or the device is fixed in the ground.
