I. BrandAt present, there are hundreds of factories producing small excavators in the market, and if there are brands that can be called up, there are 34 brands according to my personal statistics; But among these brands, how can we choose the brand we like? Each brand has its own production philosophy and target customer groups. The brand also represents the owner's taste, cultivation and style of doing things, etc.

White smoke, blue smoke, and black smoke are common malfunctions of excavators.

The chemical energy of the diesel oil is converted into mechanical energy by the diesel engine, the mechanical energy is converted into hydraulic energy by the hydraulic plunger pump, and the hydraulic energy is distributed to each actuator (hydraulic cylinder, rotary motor + reducer, walking motor + reducer) through the hydraulic system, and then the hydraulic energy is converted into mechanical energy by each actuator. Realize the movement of the working device, the rotation of the rotating platform and the walking movement of the whole machine.1.

1. Ensure smooth discharge of hot air(1) Do not open the radiator compartment partition or period as the heat transfer process of the vortex assembly at random. It is not always easy to do so because of the influence of high temperature air removal.(2) A number of exhaust ports in each cabin are well known, so insist that the protections and exhaust port pumps at the bottom of the engine will prevent objects from appearing and placing or blocking exhaust heat. Is. Reducing the intake star will increase the enginetemperatures in the cabin and increase intake air temperatures.

Technical parameters:- Weight of the whole machine: about 2 tons- Power system: diesel engine, power 12-15 kilo watts- Maximum digging depth: 2.5-3 meters- Maximum digging radius: 3.5-4 meters- Maximum digging height: 3.2-3.5 meters- Travel speed: 1.5-2.5 kilometers/hour- Climbing capacity: 30°.- Bucket capacity: 0.05-0.10 cubic meters- Hydraulic system pressure: 16-20Mpa- Fuel tank capacity: 30-50 liters- Track width: 200-250mmApplicable scenes:- Municipal engineering: sewer trench excavation, road repair and other operations.- Landscaping: tree transplanting, flower bed leveling, soil excava

Small mini excavator bypass valve failure today to analyze the small excavator central bypass valve failure.1. Boom lift, bucket low-speed digging and unloading, the central bypass valve is stuck in the open position, the oil output of the main pump to return to the hydraulic oil tank, the boom rise and bucket work circuit is not accessible, remove the central bypass line shaft for cleaning.2.

Small excavators are mainly used in agriculture, road construction, urban construction and other industries, the specific uses are as follows: 1, agricultural industry: small mining function efficient to help farmers crop planting, farmland land leveling; Digging trenches and fertilizing orchards; Deep digging of greenhouses and drainage ditches; The renovation of dry latrines, the construction of houses, the digging of foundations and even the use of small excavators for livestock farms to help them raise pigs and become rich. 2, road construction industry: In addition to the popula

The working scenarios of mini excavators can always change, but we have different precautions for different working scenarios.First, we have a small hydraulic excavator specialized in tunnel work. Since this kind of small excavator is more suitable for tunnels, because its overall structure is simple and it can relatively carry out tunnel conditions in layers, the safety performance of this small excavator is also very high.Therefore, our small excavator can be applied to the working raft of tunnels, but it should be noted that the overall device of this small excavator is like.

The original excavator is manual, from the invention to the present has been more than 130 years, during which it has experienced the gradual development process from steam driven bucket rotary excavator to electric drive and internal combustion engine driven rotary excavator, the application of electromechanical hydraulic integration technology fully automatic hydraulic excavator. In 1951, the first fully hydraulic backhoe was introduced at the Poclain plant in France by Case, a pioneer in crawler and wheeled excavators.

Operating weight: One of the three main parameters of the excavator refers to the total weight of the excavator with standard working equipment, driver and full fuel. The operating weight determines the level of the excavator and also determines the upper limit of the excavator's digging force.  2.
