Q: What is a surprise?: A group of enemy, along both sides to end point encircled fast maneuver and attack the enemy with pincers reached encirclement. A pincer attack is our army's main encirclement style, is conducive to quickly before exposure, to highlight the enemy wings isolated, behind the closed encirclement ring.Two, with a positive blocking force, main attack from the enemy's flank to the rear side roll, is your enemy encirclement. You are usually on the main side of the assault assault behind enemy lines, pointing to his weakness, cut off the attack the enemy's retreat, is a kind of method, weak key focus of the operation, can move the enemy situation, rapidly changing battlefield situation.Three, from more than one direction with centripetal attack, the enemy encircled an attack from various directions method. Attack from various directions is a useful method but is rare in the encirclement, our army, because it requires the onslaught of troops in the appropriate position, can from different directions pre raid target fighters. This is usually the enemy in a battle or war on the inside, the strategy has been surrounded, fragmented the encirclement method.

Q: What is the output current of the inverter to be measured? Why not use the current clamp meter?: There may be sinusoidal PWM modulation, PWM modulation or non sinusoidal waveform, harmonic content of output is high, the fundamental frequency is not necessarily 50Hz waveform, so if the clamp current meter measurement, bandwidth is not enough, in addition, a table cannot be used to measure the frequency of electric quantity.

Q: What's the difference between the brake caliper and the brake disc? What's the usage?: The brake caliper and the brake disc are arranged on the disc brake. When the automobile is in motion, the brake disc rotates with the wheel, and the brake caliper is fixed. When braking, the brake clamps the brake disc to perform the braking action

Q: What kind of material does the Tong Tong do well?: Inclined pliers are generally made of cast iron. A general term for an alloy consisting mainly of iron, carbon, and silicon. In these alloys, the carbon content exceeds the amount retained in the austenite solid solution at the eutectic temperature.Diagonal pliers mainly used for cutting wire, wire components redundant, is often used instead of ordinary scissors shearing insulating sleeve, nylon wire etc..

Q: How are the external clamps defined in the drilling?: Internal fitter1) responsible for the operation of liquid gas tongs, do the next single preparation, drilling wellhead inspection tools and observation, put on the single number.2) inspection and control of turntable, winch, transmission equipment, brake system and safety protection facilities, equipment maintenance, lubrication for the floor, fill in equipment operation record.3) responsible for the liquid gas tongs, roller kelly bushing, mousehole pliers, wellhead tools inspection, management and use, achieve complete, clean, location display.

Q: How about the use of hemostatic forceps?: With the use of basic surgical scissors forceps, but let go when the thumb and forefinger holding forceps is a ring, the middle finger and ring finger in a ring, the thumb and ring finger gently on the top.

Q: The function and notice of sharp pliers and oblique mouth pliers: After each use of pliers, because there will be grinding marks on the blade, it is recommended to clean up after use dirty, and oil maintenance, can prevent the blade aging oxidation. Cutting edge does not suggest grinding, because blade hardness and caliper hardness is not the same. The blade is quenched and tempered. So some pliers wear harder and harder.Some pliers is lifetime warranty, such as Star.

Q: So many varieties of pliers, where to buy the most complete?: The cutting edge of a pliers can be used to cut rubber or plastic insulation on soft wires. The jaw of the pliers can also be used for fastening or loosening the nut. The insulated plastic pipe of pliers is over 500V. With it, it can cut wires with live electricity. After hardening, the strength, wear resistance, fatigue strength and toughness of the pliers have been enhanced, so that the service life of the pliers is very high.

Q: Can the clamp type ground clamp clamp the flat iron directly in front?: A resistance table ring which is a special electromagnetic converter into the cable through the front end card is AC constant voltage 1.7kHz, the current detection circuit, after filtering, amplification, A / D conversion, only the current generated by the 1.7kHz voltage is detected. Because of this, a ground resistance meter out of small current grounding commercial AC and high frequency noise caused by the device itself, in order to obtain accurate measurements, but also because of this, a ground resistance meter has the advantages of online measurement. In fact, the meter measures the impedance of the whole loop, not the resistance, but, in general, they are very small. A ground resistance meter immediately will be displayed in the LCD display, when no bayonet card, it can display the "open jaw" or similar sign on LCD.

Q: What are the requirements for safety tongs and speed limiters?: Overspeed governor speed setting, the adjustment part should be sealed down. For a speed limiter with a record shift or verification period up to 5 years, it shall be checked again. (7) the speed limiter shall have a nameplate, and the nameplate shall have an electric protective switch, working speed, speed of action, manufacturing unit and so on
