What kinds of chainsaws are there?

Chain saws generally refer to chain saws, which are divided into gasoline saws, chainsaws, pneumatic saws and hydraulic saws according to different sources. The advantages and disadvantages of these four kinds of power chain saws are obvious:

1, gasoline saw: highly mobile, suitable for field mobile operation. However, it is noisy, troublesome to maintain and generates more heat.

2, chain saw: stable power, fast start, heavier than other saws. But if the line is too long, it will be inconvenient to move.

3, pneumatic chain saw: safe and pollution-free, low noise, light weight. However, it must be equipped with an air compressor, which increases the area and is limited by conditions.

4. Hydraulic chain saw: it has enough power, but it starts slowly and works smoothly. The volume of hydraulic pump station is smaller than that of air compressor. The cost is higher.

Extended data:

The basic structure of chain saw is generally composed of engine, sawing mechanism and transmission mechanism. When working, the power drives the saw chain through the transmission mechanism, so that the saw chain moves continuously along the guide plate to cut wood.

1. Engine: The engine is generally a single-cylinder air-cooled two-stroke high-speed gasoline engine. In order to adapt to the work of chain saw in different cutting directions and different positions, a diaphragm carburetor with an oil pump is adopted, which drives the diaphragm to pump oil through the pressure pulsation in the crankcase, so that the engine can supply oil normally at any position.

In addition, new structures such as transistor contactless magneto ignition system and one-way valve intake system are also widely used, thus improving the performance of the engine.

2. Sawing mechanism: Sawing wood structure is the working part of chain saw, including driving sprocket, saw chain, guide plate, saw chain tensioner and wood inserting teeth. The driving sprocket rotates under the power of the engine, and then drives the saw chain to move along the guide plate for cutting operation.

3. Transmission mechanism: The transmission structure includes centrifugal friction clutch and reducer. Bevel gear reducer (only used for high-handle chain saw) is generally used as the reducer, which is convenient for the horizontal and vertical adjustment of the sawing mechanism relative to the machine body to meet the needs of different sawing directions during logging and timber making.

Chain saws are widely used in world landscaping, and the development trend of chain saws is to adopt new materials, new processes and new structures to further reduce the weight of chain saws. Reduce noise and vibration, reduce air pollution and improve operating conditions; Adding safety protection devices to improve the reliability and safety of use; At the same time, we will continue to improve the new chain saw and remote control chain saw driven by rotating engine.
