Proper use of hammer should pay attention to what matters it? Prepare broken before (1) When the tubing was found loose, one immediately cease operations. When the hammer high or low pressure hose excessive loosening, stop work immediately and immediate inspection and repair. At the same time as a precaution, should also check whether there is leakage happens elsewhere, domestic small excavator, the operator should pay attention to the stringent requirements of the situation hit points. (2) Avoid hammer situation in the absence of the target air strike. When a rock or object has been shattered, stop hammer blow action, sustained aimless impact will only result in the precursor and main screw loose and damaged, or worse still loss and construction machinery body. Combat situation occurs aimlessly, unless they are improperly inserted, but the hammer will affect the use of shaking. Do not forget the guards pushing heavy objects as tools, so will only result in (3) Do not push to hammer heavy or large stones work fender screws, drill rod rupture and damage hammer, boom would break even the main reason. (4) Do not forget the drill rod to shake when using a broken job, such as an attempt to shake the drill rod using screw and drill rods are subject to possible rupture. (5) Do not use the strike action over a minute of continuous operation. When the same point pummeled more than a minute and failed to break the target, change the selected point attempt hit again. Trying to continue to crack down on the same point will only cause excessive wear drill rod. (6) When the object of the stone is large or hard to select for the job from the broken edges. Whether another big and hard stones again, select from the edge began to crack usually easier to break way. (7) Operation select appropriate engine speed breaker. An appropriate engine speed crushing operations. Usually not local to upgrade the engine speed exceeds the speed needed for the work, and failed to strengthen efforts to combat the strength of the time; on the contrary; will make the rapid increase in temperature of the hydraulic oil, lubricating ability and cause decreased ability to work to the detriment of and the risk of piston and valve.泰安嘉 and Heavy Machinery Co., Ltd. Construction Machinery Vibration engine vibration isolation 1, rubber isolation conventional engine with flexible support to reduce vibration isolation device structure is simple, homemade mini excavators prices, low cost, reliable performance. Rubber bearings are generally mounted on the frame, mini-excavators, according to the forces into compression type, shear and compressive shear complex type. Simple and compact structure, easy to manufacture a wide range of applications due to high natural frequency, is generally limited to the use of the vertical direction. Shear vibration at lower frequencies, but the intensity is not high. Compression shear complex combines the advantages of the first two structures to meet the durability and reliability, which is currently the most widely used at home and abroad. In order to anti-vibration rubber support system has good damping properties, the spring constant parameter form requires the same direction, which would also allow some form reduced in size. 2, spiral wire rope isolator rope as damping element, with variable damping parameter performance low frequency and large high frequency low stiffness, which can effectively reduce the body vibration. Compared with the traditional rubber vibration source, with anti-oil, anti-corrosion, anti-temperature, high temperature, anti-aging and advantages of small size, mini-excavators much money, isolation effect depends on its nonlinear hysteresis characteristics. 3, the hydraulic isolation hydraulic support system is a support structure of a conventional rubber composition integral with hydraulic damping, in the low frequency range to provide greater damping of the engine vibration value plays a significant role in the rapid decay, high frequency having a lower The dynamic stiffness can effectively get reduce cab vibration and dry sound.泰安嘉 and Heavy Machinery Co., mini-excavators, mini-excavators price list, Kerry and Heavy Industries (quality businessmen) are provided by 泰安嘉 and Heavy Machinery Co., Ltd ..泰安嘉 and Heavy Machinery Co., Ltd.
