The difference between power tools and pneumatic tools power tools power tools power tools is a low-power electric motor or electromagnet as power, through the transmission mechanism to drive the operation of the working head of the tool.

PK difference in which pneumatic tools pneumatic tools are mainly the use of compressed air to drive the pneumatic motor and the external output of kinetic energy work of a tool.

PK results 1, working capacity: both provide a variety of different ways of working, but the pneumatic tool speed adjustment and output power adjustment is simple, in the same output power, more small and lightweight. In addition pneumatic tools in the speed range can provide more levels of choice, there is no heat and overload failure, overload when starting the tool only stops rotating, once the overload phenomenon is lifted is back to normal operation.

2, the ability to adapt to the environment: in terms of environmental applications, pneumatic tools are more resistant to water. Although soaking water is harmful to the tool, but not like hardware power tools may produce electric sparks, triggering harm. And because pneumatic tools can use internal combustion engine air pump, can be adapted to a variety of bad or harsh environment.

3, economic: from the economic performance, power tools, the initial investment is less, but long-term energy consumption is higher, and tool maintenance, replacement costs are also higher. Pneumatic tools need to establish the initial investment in pneumatic piping equipment, but the long-term use of energy consumption and tool maintenance costs are lower.

Power tools to buy 1, use: according to the need to distinguish between family or professional use, because most power tools are designed for professionals, in the purchase should distinguish between professional and general family tools. Usually the difference between professional and general household tools in the power, professional tools with more power, general household input power does not need to be very large.

2, appearance: the outer packaging pattern is clear and unbroken, the plastic box is strong, buckle solid and durable. Tool appearance of uniform color, plastic parts surface without obvious shadow wire and dent, no scratches or bumps, assembly misalignment between the shell parts ≤ 0.5mm, aluminum casting paint smooth without defects, no oil on the surface of the machine. The handle of the switch is flat when held by hand, and the length of the cable is generally not less than 2 meters.

3, nameplate parameters: should choose to have "3C" certification of qualified products, power tools, nameplate parameters should be consistent with the CCC certificate. Tool instructions should be the manufacturer and production plant's detailed address and contact information. Nameplates or certificates of conformity should be traceable to the batch number of the product.

4, convenience: compact size, highly integrated power tools will undoubtedly be higher in the ease of use than the volume of large, single-function products. Recommended in the purchase of home power tools more on related products for side-by-side comparison, try to choose feature-rich, compact size, simple structure, easy to store the power tools to buy.

5, safety: hold the tool by hand, turn on the power, frequent manipulation of the switch, so that the tool starts frequently, observe the tool switch on and off function is reliable. At the same time to observe the site of the television, fluorescent lamps whether there are abnormal phenomena. In order to confirm whether the tool is equipped with an effective radio interference suppressor.

6, vibration and sparks: the tool is energized to run for one minute, running with a hand grip, the hand should not be obvious to feel any abnormal tremor, observe the commutation spark, its commutation spark should not be more than 3/2 level, generally from the tool's inlet to the inward, in the surface of the commutator should not be obvious arc light.

7, noise: most household power tools in use will produce a certain amount of noise, however, the use of noise there are high and low points. Suggestions (especially families with children and the elderly) to buy home power tools when the tool for a trial, to see whether the use of the noise of the power tools in the acceptable range.

Power tools use precautions food 1, general occasions should be used Ⅱ class products, in wet places or metal frames and other conductive places should be used Ⅱ or Ⅲ class products. In metal containers, pipelines, boilers and other narrow places should be used Ⅲ products. If the use of Class I products, should be in accordance with the safety requirements of other necessary safety measures.

2, before use should be carefully inspected, the appearance of no damage, the switch action is flexible and no jams, power leads and power tools should be intact shell. With 500V megohm meter to measure the insulation resistance between the winding and shell shall not be less than 0.5 megohm. Metal casing of hand-held power tools should have a reliable protective ground wire.

3, the power outlet must be kissed power tools power plug, the equipment away from rain and humid environment. In the outdoor use of power tools when the use of outdoor use is allowed to extend the power cord, and the power cord away from heat, oil, sharp edges or parts of the tool in motion. The operating switch should be placed within reach of the operator.

4, according to the form and characteristics of power tools with good personal protective equipment, wearing appropriate clothing. Open the power tool before the adjustment screwdriver or wrench removed and removed, the use of the relevant safety regulations should be strictly adhered to the correct connection and use, do not overload, stay awake, focused and sensible operation of power tools.
