Q:Modern 335-7 excavator hydraulic oil temperature at how many degrees normal?
6 、 adjust the system pressure according to the requirements, avoid the pressure is too high, make sure the safety valve, overload valve and so on in normal condition work7, regular maintenance, avoid other parts wear too much to cause leakage. Timely replacement of volumetric efficiency of the hydraulic pump, because of its internal leakage will make the pump shell temperature rise, accelerate the system heating up8, regular inspection of engine speed and fan belt tension degree, so that fans keep enough speed, adequate heat dissipation, so that the equipment in good running condition
Q:What should we pay attention to when purchasing excavators?
Excavators should pay attention to the chassis, hydraulic systems, walking systems, walking systems of steel (especially rail training and bucket teeth) is normal.Open the engine cover and check the exhaust pipe for signs of smoke. You can pull out the dipstick and check whether there is smoke. Too many usually illustrate the need to replace the piston rings of smoke, and may soon have to overhaul the engine also includes basic inspection and check the radiator and engine oil liquid, the corrosion degree of the engine and check the battery, check around there is no obvious leakage.Excavator, also called excavating machinery, is a kind of earthmoving machine that uses bucket to excavate material that is higher than or lower than the machine surface and is loaded into transportation vehicle or unloaded to the stacker. Excavators are mainly made of soil, coal, sediment, and soil and rocks that have been pre - loosened. From the development of engineering machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are operation weight (quality), engine power and bucket bucket capacity.
Q:The reason why the excavator holds down the engine is 150
[cause of trouble]1 hydraulic large pump failure2 excavator two valve problems3 hydraulic pump regulator variable chaos will also choke machine flameout failureFourIs the confluence valve of the solenoid valve blocked?5 hydraulic oil will also be more excavators hold machine flameout failureSixIf the fuel supply is poor, check whether the oil pipe is blocked or leaking[corresponding cause of failure]1 there is a problem with the circuitTwoCheck the wood and see if it's blocked. If you don't see it, get into the system3 there's something wrong with the engine4 there is water in the fuel lineFiveIf the air enters the fuel pipe, the excavator will stop and stall6, the gas supply is poor, causing the engine to stall7, the power of the engine is insufficient to achieve the power required by the hydraulic pumpEightThe hydraulic part has the stem to clamp, also can the excavator hold down the engine to extinguish the faultNineValve stem movement is not smooth, resulting in hydraulic power is greater than the output power of the engine, so the engine will stall[supplement]Corresponding troubleshooting:1., although you said that the inspection is no problem, but still suggested from the most basic fuel road cleaning, replace all filter elements, began to check. The diesel pump is removed from the oil line to see if the injection length can reach about 6~7cm.2. small arm and walk, mainly pump 2 oil supply, check the main pump cleaning 2 of the regulator.3. choke 90% is fuel road failure, it is best to carefully check the oil circuit to confirm that there is no leakage of space, such as pipe joint seal damage, filter is not in place, oil-water separator, water supply cover is not tightened, etc.. Direct connection with fuel tank test can be used.
Q:Explanation of tail slewing and tailless rotation of excavators
Moving arm side shift deviceThe front part of the body equipment boom side shift device, so as to realize the direct mining work similar to wall area, without frequent driving. With the small tail structure, narrow areas should be handled freely.Tailless slalomThe Kubota small excavator uses a small, tailless, rotating structure that does not exceed the width of the vehicle when the upper part is turned, so it is free to operate in narrow areas.The latest hydraulic systemThe system is not affected by the load size, but the hydraulic fluid flow is fully allocated according to the amplitude of the joystick. Therefore, the operation can be done easily according to the intention of the operator. At the same time, because of the small load of the engine and the unnecessary loss of the flow rate, various micro operations and compound operations can be realized.Original engineKubota is one of the few independent manufacturers of engines. Equipped with a small excavator engine, condensed for nearly a century of experience and technology, power surging, can meet all kinds of harsh occasions of operation.Clean engineEmissions of compounds that cause environmental pollution are minimized, a low fuel consumption clean engine that meets the next generation of needs.
Q:What can an excavator do?
Excavators can not only dig earth, sand and gravel, but also can be used as small lifting equipment, flexible and flexible, and rarely affected by the geographical environment, not only can rescue, but also self-help.
Q:Excavator standard
(7) GB, 25684.5-2010, safety of earth moving machinery, fifth parts: requirements for hydraulic excavatorsAmong them, GB/T 7586-2008 and GB/T 9139-2008 are the main specifications of excavator performance, and GB 25684.1 and GB 25684.5 are mandatory standards for excavator safety.
Q:Komatsu excavator GPS positioning system, how to go inside to see?
Komatsu with "Kang Chashi" global positioning system, can accurately locate the position of the machine (track), fuel consumption, work status, work quantity, the amount of fuel (to prevent without permission to put the oil, water temperature, oil temperature).
Q:How do you drive the forehand and backhand drive of an excavator?
As we all know, the hydraulic excavator operation is accomplished through two handles, two handle before and after, left and right four directions, respectively control the excavator and the moving body part arm, bucket rod, and the rotating bucket. But according to the corresponding way, the operation mode of excavator is divided into two kinds, "left and right spin" and "front and back rotation". Then, I will talk about some differences between them.Two modes of operationThe first kind is the Japanese second-hand import machine and senior veteran driver as the representative, the left hand handle of the front, back, left and right corresponding control is the excavator's right rotation, left rotation, bucket extension and bucket recovery. We used to be referred to as "front and back spin"".The second type is the domestic new machine and the new generation of young drivers as representatives, left hand handle of the front, back, left, right, respectively, corresponding to the control of the excavator's bucket stick, bucket recovery, left rotation and right rotation. We used to be referred to as "left and right spin"".There are people who have called these two modes, "mobile phone" and "mobile phone", but due to the lack of a unified nomenclature, caused the differences on the way, before and after rotation is called mobile phone, the mobile phone is called reverse rotation, but also to rotate around the mobile phone is called, before and after the rotation is called reverse mobile phone. So to avoid confusion, said only this, before and after the rotation and rotation, to note here is "mobile phone" is refers to the rotation, and rotation or rotation before and after the "anti mobile phone", two kinds of the different mode of operation is only the left hand excavator operating handle, right invariant handle mode.
Q:The difference between backhoe and hydraulic bucket excavator
Its structure is mainly composed of engine, hydraulic system, working device, driving device and electrical control part, the excavator working conditions required to achieve the action is very complicated, so it puts forward higher requirements for the design of the hydraulic system, the hydraulic system of engineering machinery hydraulic system is the most complex. Therefore, the analysis and design of hydraulic system of excavator has become an important part of excavator.
Q:How big is the digging bucket of Komatsu 200 excavator, what is its length, width and depth?
1, Komatsu 200 excavators digging bucket is generally 2.8 meters wide, bucket capacity in 0.8 to 0.91 parties.2, excavators, also known as mining machinery (excavating machinery), is dug with bucket above or below the machine surface material, and loaded into the transport vehicle or dump to the stacker of earthmoving machinery. Excavators are mainly made of soil, coal, sediment, and soil and rocks that have been pre - loosened. From the development of engineering machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are operation weight (quality), engine power and bucket bucket capacity.
