Excavator engine preheating benefits. 1, the diesel engine is warmed up after the engine starts can make the price of second-hand tick machines, diesel combustion more fully, reducing the emission of pollutants, thereby extending engine life. 2 Komagari machine, diesel engine lubricating oil preheating can make timely pumped to various parts of the operation, allowing the machine to give the film an effective protection, thereby extending engine life. 3 Komagari machine factory direct, diesel engine warm-up can make the thermal expansion of the components of the engine to reach consensus, thus extending engine life. After 泰安嘉 and Heavy Machinery Co., Ltd. Hydraulic Pump severe wear us find the cause of the fault (1) Check the boom cylinder leakage case based on the following three points. The easiest way is to raise the boom to see if there is a significant decline in freedom. If the fuel tank drop significantly the disassembly inspection, such as worn seals should be replaced. (2) Check the control valve. First clean the safety valve, check valve body wear, such as wear and tear should be replaced. If after the safety valve remains unchanged, and then check the control valve spool wear, the gap is generally limits the use of 0.06mm, severe wear and tear should be replaced. (3) Hydraulic Pump pressure measurement. If the pressure is low, then make adjustments, plus the pressure is still not tune up, then pump heavy wear. Generally Komagari machine prices, resulting tape can not raise the boom was mainly due to:. A hydraulic excavator 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. Pump wear and tear aggravated by long working hours, temperature rise, the resulting wear of hydraulic components and seals of aging, damaged, loss of sealing ability, hydraulic oil deterioration, leading to failure. b. 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. c. Hydraulic system design is unreasonable. Control valves and hydraulic steering gear as a single pump series, the safety valve set pressure points 16MPa, while the rated working pressure of hydraulic excavators for 16MPa. Pumps often work at full load or prolonged overload (high pressure) situation, and the system has hydraulic shock, long-term oil changes, hydraulic oil contamination, increased pump wear and tear, so that the pump casing burst (after have been found Such failure).
