- Q: What power tools are used in the slot on the wall?
- Percussive drills work by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force. Used of natural stones or concrete. When the impact drill works, the drill chuck is provided with an adjusting knob, which can be adjusted in two ways: an ordinary hand drill and an impact drill. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, but the impact is far less than the hammer. It is not suitable for drilling reinforced concrete.
- Q: What's the function of the capacitor in the power tools?
- It acts as a phase shifter, because power tools are generally single-phase alternating current. Motor single-phase can not start operation, if you add a capacitor, you can play the role of starting and running. The capacitor turns a single-phase alternating current into a two phase alternating current
- Q: Why use helical gears for power tools?
- Good meshing performance. In the line of contact of helical gear teeth for line tilt and the axis of gear, gear engagement and disengagement began to be gradual, and stable transmission, low noise, and the meshing method also reduces the influence of manufacturing errors on transmission.
- Q: What's the capacitor on the power tools?
- Start the motor. Hand to turn and start, then you can judge the capacitance is not enough or invalid.
- Q: What is the difference between mobile electrical equipment and hand-held power tools?
- Hand electric tools include electric drill, hand wheel, impact drill, electric hammer, electric saws and other tools. Mobile equipment includes frog rammer, vibrator, terrazzo polishing machine, electric welding machine and other electrical equipment.
- Q: The insulation resistance of two kinds of hand-held power tools is not less than
- Low voltage electrical equipment and its connecting cables and two circuit insulation resistance should not be less than 1M ohms; in a relatively humid environment should not be less than 0.5M; the two circuit of the small bus insulation resistance should not be less than 10M. The insulation resistance of class I hand held electric tools should not be less than 2M.
- Q: What are the inspection and use of power tools?
- General electric tools need the current vertical special device, no private access Luanla power line, and even some conductive power line wire are exposed, only use insulation tape laps were used, the insulating layer has been aging corrosion but the power line, the reason caused by the accident too much practice. It can be easily found in related news reports.In the power tools wiring design, as far as possible to achieve a line after a control box, a control box only control a mechanical equipment, and a special person responsible for special maintenance, regular inspection. This is the primary prerequisite for safety in production.
- Q: How do you change 110 volt power tools to 220 volts?
- Or the old honest practical transformer, with imported electrical tools of the United States Lake transformer is not very good use.
- Q: Are the metal housings of the two types of power tools grounded?
- Class II tools, that is, insulated structures, all double insulated power tools. Its specified voltage is more than 50VClass II tools are not allowed to set ground devices. Generally insulated enclosures.
- Q: Can we use electric tools to do seal cutting?
- Most of the stone carving in Qingtian, including Shoushan, Bahrain, Changhua, Dandong stone, India stone and the recent hot Laos stone hardness is not high, whether it is white steel or alloy steel or tungsten steel cutter can meet your seal needs, there is no need for electric tools. A seal killer sensation is better, can be a very good expression and present your ideas and technology, electric tools because of the slow rotation speed, and can not express very well.
