2 ton smalll hydraulic digger-manufacture,factory,supplier from China

The excavator consists of a main engine and a working device... The main engine provides power and basic movements (walking and turning), and the working device completes different operating movements... The main engine includes a walking device, a rotating mechanism, a hydraulic system, a pneumatic system, an electrical system and a power plant.1. The excavator device is the support part of the whole machine, which bears the total weight and the reaction force of the working device, while realizing the excavator with a short distance.

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.

The hydraulic system where the output flow of the main pump is a fixed value is a quantitative hydraulic system; On the contrary, the flow of the main pump can be changed by adjusting the system is called a variable system. In the quantitative system, each actuator works according to the fixed flow provided by the oil pump without overflow, and the power of the oil pump is determined according to the fixed flow and the maximum working pressure.

The 2 ton mini excavator is a flexible and efficient construction equipment designed for narrow construction sites and small projects, suitable for municipal engineering, garden construction, agriculture, road maintenance and other application scenarios.

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.

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

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.

The original excavator was manual, and it has been about 140 years from its invention to 2018, during which it has experienced the gradual development process from steam-driven bucket rotary excavators to electric and internal combustion engine driven rotary excavators, and fully automatic hydraulic excavators with mechatronic hydraulic integration technology. The first hydraulic excavator was successfully invented by the Poclin factory in France. Due to the application of hydraulic technology, in the 1940s, there was a hydraulic backhoe mounted on the tractor.

The working principle of excavators can be divided into two aspects, namely mechanical drive and hydraulic control. Mechanical drive is driven by the engine to drive the transmission chain, drive the mechanical arm, bucket rod and bucket to complete the excavation and loading operations; Hydraulic control is to drive the oil circuit through the hydraulic pump to control the movement mode and action of the mechanical arm and bucket, making the operation of the excavator more accurate and efficient. In terms of mechanical drive, the core component of excavator work is hydraulic engine.
