Hydraulic pump caused the main reason for the boom can not raise the load 1. pump heavy wear. At low speed pump leak serious; high-speed operation, the pump pressure is slightly increased, but due to wear and internal leakage of the pump, volumetric efficiency significantly decreased, it is difficult to reach the rated pressure. Long working hours and increased pump wear, mountains blasting rigs, temperature rise, the resulting wear of hydraulic components and seals of aging, damage, loss of sealing ability, hydraulic oil deterioration, leading to failure. 2. The selection of hydraulic components unreasonable. The boom cylinder specifications for the 70/40 non-standard series, seals also non-standard parts, high manufacturing cost and inconvenience of replacing the seal. Boom cylinder bore small, is bound to make the system set pressure is high. 3. The hydraulic pump system design is unreasonable. Figure 1 shows, control valves and hydraulic steering gear as a single pump series, the safety valve set pressure points 16MPa, while the rated working pressure of the hydraulic pump is 16MPa. Pumps often work at full load or overload conditions for a long time, and the system has a hydraulic impact, long-term oil changes, hydraulic oil contamination, increased pump wear and tear, so that the pump casing burst. Failures and maintenance of well drilling rig in the face of us know well drilling rig is a lightweight, efficient, multi-purpose tire type full hydraulic drilling rigs for drilling in urban architecture GSHP hole. However, due to a long time in a relatively harsh environment, the sale of rigs blasting mountains, often failed unexpectedly, in order to avoid faults, routine maintenance is necessary, there often for routine maintenance Symptoms and Solutions, blasting mountains rig, small series to summarize a bit: 1. Failure: especially in the working conditions, the drill bit prone to tail broken, shards into the cylinder stuck hammer, rock dust vent is blocked, When more water down hole drilling, blasting rig Shandong mountains, the exhaust resistance is not easy to start a big impact failure. 2. Treatment: The way to deal with failure is to discover the impact does not ring, the first period of the impactor upgrade reduce exhaust resistance, blowing a portion of the water, and then slowly into the hole at the end, when if this law is not working, then Remove outer hole impactor proposed Clean or replace parts. Except in the case of complex strata make normal drilling machine sticking outside. Mountains blasting rigs, Long industry machinery (online consultation), mountains blasting rig by Dragon Machinery Co., Ltd. Shandong. Machinery Co., Ltd.
