Excavation powerlessness is one of the typical failures of excavators. For small excavators or medium and large excavators, digging powerlessness can be divided into two cases: one is digging powerlessness, the engine does not hold the car, feeling the load is very light; the second is digging powerlessness, when the moving arm or bucket bar reaches the bottom, the engine seriously holds the car, or even stalls.

Crawler mini excavator

①The digging force is weak but the engine does not hold the car. The size of the digging force is determined by the output pressure of the main pump, and whether the engine holds back depends on the relationship between the absorbed torque of the oil pump and the output torque of the engine. The engine does not hold the car means that the oil pump absorbs less torque and the engine load is light. If there is no obvious abnormality in the working speed of the excavator, the focus should be on checking the maximum output pressure of the main pump, that is, the system overflow pressure. If the relief pressure measurement value is lower than the specified value, it indicates that the overload relief valve setting value of the hydraulic circuit of the mechanism is incorrect, resulting in premature overflow of the mechanism and weak work. Then the machine can be adjusted by turning the adjusting screw.

② Excavation powerlessness and engine holding. Engine holding indicates that the absorbed torque of the oil pump is greater than the engine output torque, resulting in engine overload. This fault should first check whether the engine speed sensing system is normal, the inspection method is similar to the engine inspection method described in the previous section. After the above detailed inspection and troubleshooting, the engine speed sensing system to restore normal function, the engine holding phenomenon disappears, the excavator will return to normal.

As excavator drivers, in order to make their excavators less likely to fail, we should pay attention to the maintenance of the excavator in ordinary use.

Agricultural crawler mini excavator

  1. Engine.

Oil, oil filter absolutely must be used genuine factory parts, according to the specified maintenance cycle replacement. Older machines need more careful care, oil filter replacement time can be shortened as appropriate, in order to make the engine life longer.

Diesel fuel as far as possible to use the regular gas station to provide, even if the regular gas station to add diesel fuel, do not directly into the tank, join before filtering (more commonly used method is in the refueling mouth socks). Put water at the bottom of the diesel tank and oil-water separator before starting work every day. Diesel filter buy genuine parts, according to the specified maintenance cycle to replace the diesel filter. (To clarify, the genuine plant filter paper is fine, the impurity interception amount is large, so it is easier to block, than the secondary plant filter replacement cycle is shorter, so not a long-term non-clogging filter is a good filter)

The air filter element should be checked frequently, and the outer filter element should be blown from inside to outside with compressed air, and the air pressure should not be too high to prevent the filter element from being blown out. The inner filter should not be cleaned. After cleaning the outer filter 2 or 3 times, replace it with a new one at the same time as the inner filter.

Do not use the idle speed for a long time in order to save fuel and prevent the accumulation of carbon.

  1. Hydraulic.

Replace the hydraulic oil, return oil filter element and pilot element according to the prescribed maintenance cycle, and pay attention to whether the filter element has adsorbed iron chips and copper chips.

When using the crusher, the hydraulic oil deterioration and deterioration accelerated, the replacement cycle should be shortened.

Do not work without oil for a long time.

After replacing the hydraulic oil or hydraulic parts, pay attention to expel the air.

  1. Electrical.

Pay attention to waterproof, do not wade into deep water operation, do not use water to flush electrical parts directly when doing cleaning.

Do not pile up debris in the battery box, especially metal tools, etc., easy to start a fire.

Do not use wire and copper wire instead of insurance, and do not replace the insurance with non-standard.

Excavator long-term parking to dismantle the battery line to prevent power feed.

  1. Machinery.

Rotation reducer, walking reducer replace gear oil according to cycle.

The pin part pay attention to clean up the mud and debris, filling grease.

Water operation, water over the rotary gear ring, pay attention to the replacement of the rotary gear ring grease.

Pay attention to the cylinder rod to prevent rust.

When the excavator is parked for a long time, apply grease to the exposed metal part to prevent rust.

  1. Structure.

Check daily whether the pin bolt is loose, off or missing, and tighten it in time.

Check the structure every day for cracks and deformation.

Pay attention to the surrounding environment when parking the excavator, park it on solid and stable hard ground, not on the river, cliff side, under the slope to prevent accidental danger.

When parked, the bucket cylinder is completely retracted and the bucket falls to the ground to prevent the cylinder from being hit.

Excavator with fuel oil is diesel, not gasoline. Hydraulic oil is high viscosity (more than 120ls) anti-wear hydraulic oil, used for pin lubrication general general lithium grease can be, that is, Kunlun of a barrel of butter. Excavator is fully hydraulic transmission, no transmission reducer this thing, the lubricant can be exempt, pumps and valves and motors, rotary reducer, etc. are directly lubricated with hydraulic oil.

Agricultural small excavator

For excavators such as heavy-duty and long-term work of construction machinery, the use of diesel engines is necessary. Because of the low cost of diesel engines, fuel-efficient, high power, low-speed torque, torque adaptability (power curve than gasoline engine stable). First of all, fuel saving is the first, huh seen how some engineering teams with excavators, right? When the work is busy to change people do not change the machine, people stop non-stop, if the use of low calorific value of gasoline, then buy oil must buy poor. Excavator as the harsh conditions of the use of construction machinery, to be reliable, to be stable. To put it bluntly is to “operate”, oh, I guess you know from common sense, diesel engines than gasoline engines more than operation.

Diesel engine speed is low, less wear, low heat load, and basically cast iron body, quite solid, large volume of space, cooling water channels lube oil channels are easy to arrange, unlike the gasoline engine is so small, but also cast aluminum and even magnesium-aluminum alloy what to come, even if the process is good, the process is poor is not resistant to burning; diesel oil pipeline injection nozzle diameter of what are relatively large, not easy to plug, and no gasoline engine what easy to Erosion of the spark plug, easy to break the distributor and a large number of ECU electronic control system, electronic systems with more, stability is not.

At the same time there is another reason is that the gasoline engine as a high-speed heat engine, not quite meet the needs of the excavator conventional constant power control system. Medium and large excavators in the “standard” (S) and “fast (F)” mode of work, the use of variable control system, so that the diesel engine fixed speed in the rated power speed (lower speed) stable work, this speed to save fuel, and this working condition has a certain This speed is fuel-efficient and has some advantages similar to stepper motor, that is, the output torque changes without much change in speed. It makes the excavator work steadily, and the digging force is determined by the load (digging to soft soil and minus digging force increase speed, digging to cement stone and plus digging force decrease speed), while the engine works at constant rated power and speed. Gasoline engine response to the load is more sensitive than diesel engines, high speed, but heavy-duty is not good, resistance to a slight increase in speed drop a lot, in addition to fuel consumption this shortcoming, but also make the control complex, working conditions change more, with the pump swash plate to adjust the output at the same time, but also constantly refueling and fuel reduction to maintain a constant speed, too complicated but fuel-saving effect is not good. And let the gasoline engine in the “heavy-duty” (H) mode of work, obviously is not wise, it provides limited torque, and fuel consumption increased sharply.

Carbon deposits are dense carbon oil compounds. The oil accumulates on the surfaces of engine cylinder heads, cylinder liners, pistons, valves, combustion chambers, fuel injectors, etc. due to inadequate combustion of diesel fuel and oil seeping into the cylinders. Solid layer carbon deposits. The poor thermal conductivity of carbon deposits, long-term accumulation may lead to localized overheating of components, severe nozzle, valve ablation, piston ring blockage and pulling cylinder may lead to serious failure. In addition, if carbon deposits accumulate on the surface of the combustion chamber, it will also lead to an increase in compression ratio, premature ignition, detonation, etc., which seriously affects the engine’s power performance and fuel consumption. Therefore, agricultural excavators must be regularly inspected for carbon deposits and repaired by thoroughly cleaning them in a timely manner.

Method 1: Mechanical grinding method

The easiest and most straightforward method for carbon deposits is to mechanically polish them using tools. You can use a wire brush, bamboo or emery cloth to wipe the carbon deposits. For carbon deposition on specially shaped parts, special tools can be used. For example, carbon deposits around injector nozzles can be cleaned with a fine wire brush, and pressure chambers are made of special scraping needles. Valve guide bearing and valve seat carbon can be removed by cylindrical wire brushes.

Mechanical grinding method is difficult but inefficient, poor cleaning effect, and cleaning process leaves many small scratches, which destroy the smoothness of the parts and easily become new carbon accumulation points. So it is not recommended

Method 2: Spraying nucleus method

The nucleus spraying method is similar to the principle of sandblasting, but the particles sprayed are not sand grains, but crushed particles of walnuts, peaches and apricots with a softer texture. Nucleus spraying the use of high-speed airflow will be sprayed walnut sand to the surface of the parts to remove carbon and oil, in addition to carbon high efficiency, thorough and clean. However, this method requires special equipment and is difficult to adopt widely.

Method 3: Carbon removal additive

In addition to carbon deposit additives, carbon additives usually consist of four components: carbon solvent, diluent, retarder and active agent. When in contact with the carbon deposit, it can be softened and lose its ability to bind to the metal without damaging the metal parts.

This method is the most common method of carbon removal because it is efficient, effective and does not cause damage to the parts.

According to statistics, only about 20% of the engine output becomes the effective work of the excavator. In addition to the effective work, about 40% of the hydraulic components are lost, about 20% of the movement of the body and work unit is lost, and about 20% of the throttle speed control is lost.

Crawler mini excavator price list

Through simulation, Carter obtained the energy loss distribution of each excavator component during the loading process. The energy loss of pump and control valve is about 2/3, and the energy loss of control valve is larger because many functions of control valve are integrated in it. The internal complexity of the oil circuit makes it difficult to reduce the pressure loss. Three-dimensional modeling analysis was required, and the passages were enlarged as much as possible to ensure strength and efforts were made to reduce narrow sections. In addition, the primary overload characteristics of the safety valve need to be improved and leakage should be reduced as the pressure of the safety valve approaches.

Energy saving measures for the general hydraulic system

  1. This variable pump uses pressure-sensing constant power control to effectively utilize engine power and change throttling speed to volumetric speed to reduce energy loss.
  2. Reduce the intermediate unloading loss and speed loss in the micro-operation process. Open center oil circuit using negative flow control or positive flow control, closed center using load-sensitive pressure compensation control, so that the middle time oil pump work in low pressure and small flow rate, only supply oil system. Cool and lubricate and flush a small amount of oil. Keeps the system in standby and responds quickly during operation. When operating micro-operation speed control, the oil pump can automatically change the displacement and oil supply according to the required flow rate.
  3. When the high pressure overload cuts off the overload overflow, the oil pump can automatically reduce the flow rate to a small value. In actual operation, the overflow operation is rare and the energy saving effect is not significant.

This kind of bearing has a larger bring capacity of axial tons contrast with the deep-groove round bearings. The structure of the bearing shows that it runs really well under high rotational rate.

Cylindrical roller bearings primarily consist of 3 main sections: The internal bearing race fits well on the turning shaft, or can in fact be the shaft itself if the shaft steel is hard enough. The outer race is a uniform and solidified collar that fits inside the bearing owner birthed. roller bearing manufacturer There must be an enough number of consistent straight rollers to completely load the space between the 2 races without binding with each other. These bearings will certainly last virtually forever if secured, kept very clean, as well as oiled with high film strength-bearing oil.

This kind of birthing item has numerous applications. They are suitable for electric motors, automobiles, transmission shafts, gear shafts and more. On lorries, they are optimal axle bearings for dump vehicles, cement mixers, bulldozers, tons haulers, as well as lifts. They can additionally be applied in very big commercial devices such as presses, builds, conveyors, equipment boxes and rolling mills, and so on. Double row cylindrical roller bearings are proficient at the spindles of maker devices.

Are you trying to identify exactly how to create, organize, and offer a 2nd or brand-new office? Maybe you’re renovating, re-facing, or recreating.
