How to repair the dynamometer:
I believe that many users in the use of the dynamometer process will inevitably encounter some glitches, these glitches will affect the efficiency of our work. In order not to affect user productivity, small series to put together this method of data maintenance dynamometer, hope can help to you.
method one,
1, first check your dynamometer connecting line sensor is connected,
2 , short circuit or open circuit, as well as welding whether there is a phenomenon of welding.
3, and then check your meter is fully charged, if the charge is not enough, then it is easy to cause, can not normally use the boot, the value of instability, on-line beat. When using logic pens and oscilloscopes to detect signals, be careful not to make the probe contact two at the same time
4. Measure the pin, because the essence of this situation is to form a short circuit under power.
Method Two,
1. When using the multimeter's ohmic block, remember not to measure with electricity. A power detection filter capacitor in the dynamometer should first electrolytic.
2. The positive and negative electrodes of the container should be short-circuited, and do not use a lead line instead of a wire to discharge the capacitor because it is easy to blow the core wire. A 220V, 50W bulb with a cap lead can be taken and connected to both ends of the capacitor. The bulb will flash at the moment of discharge.
Method three
1, each of the measured parameter can be an ordinary point welding hand stitches on the multimeter test leads to the direct measurement points piercing paint, paint peeling without large area, this causes the oxidation of the copper foil.
2. In the case of a maintenance failure in a wet environment, it is necessary for the circuit board's circuit multimeter to measure whether each point is smooth or not . Because the major fault in this case to the circuit board is a copper foil etching corrosion we can use the content of 95% industrial alcohol and wipe cleaning, in order to avoid corrosion of larger masks.
3, the internal circuit is detected the load cell, and if the contact element is mounted on a circuit board coated with insulating varnish.
Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat Stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent "coking" during processing. It is an effective thermal stabilizer added in the processing of PVC films, and can prevent finished films caused by excessive exposure to sulfides.
Mainly used to produce stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.
Widely used to make cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and others Organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a wax paper polish, and an emulsifier for glyceryl stearate.
The product is used as a lubricant, defoamer and food additives in the food industry as a raw material for glyceryl stearate, sorbitan stearate, and sucrose esters. Used as the raw material of additives and the raw material of daily chemical products.
