Gregory teacher saying laboratory) : 17 scales using and maintenance
2014/9/11 Viewers:
Hello, welcome to ge the teacher saying laboratory.
Has simple structure, convenient and practical, electronic balance, weighing speed and other characteristics, is currently widely used in enterprises and laboratory, is used to determine the mass of the body.
At present domestic use a wide range of electronic balance, whether domestic, and imported;Regardless of whether they are big weighing, or small weighing;Regardless of whether they are of high precision, or low accuracy, its basic structure principle is the same.How to properly install, use and maintenance of electronic balance, and get the right weigh as a result, is one of the effective methods to guarantee product quality.
Verification work at the scene found that the balance of many enterprises have no installation, use and maintenance according to the requirement, and the measurement data deviation is large, more than the maximum permissible error verification regulation requirements.To make the enterprises engaged in personnel obtain accurate weighing results using the scales, prolong the use fixed number of year of the scale, will now correct installation, use and maintenance of electronic balance need to pay attention to the problem of this article is as follows:
1, the installation of electronic balance room environmental requirements
1) room should avoid direct sunlight, had better choose just room or use shading;
2) should be far away from the source, such as railway, highway, vibration machine, such as mechanical vibration, cannot be avoided when the anti-shock measures should be taken;
3) should be far away from the heat source and high electromagnetic fields such as environment;
4) should be a constant indoor temperature, and is better to 20 ℃ or so;
5) work indoor relative humidity between 45% and 75% win is the best;
6) work inside should be clean, avoid the influence of the air;
7) the influence of the indoor work should be no corrosive gas;
8) workbench should be solid and reliable.
2, install electronic balance before cleaning requirements
1) first of all, with brush and remove the aggradation, etc;
2) weighing room or near the magnet steel should use wet dust removal and so on silk, don't let the dust falls to the magnet steel and stolen goods, to cause the balance failure;
3) use damp flannel, etc will scales and parts to wipe clean (unfavorable use solvent);
4) with a clean will balance and its components, such as silk cloth to wipe clean, ensure the balance of clean.
3, electronic balance considerations before operation
1) choose the voltage profile, electronic balance, should be consistent with use of external power supply voltage;
2) electronic balance should be in the level of state;
3) electronic balance should be preheated according to the requirement of the specifications;
4) to weigh the volatile and corrosive goods, to flourish in an airtight container, in order to prevent corrosion and damage the electronic balance;
5) balance should be a constant indoor temperature and humidity, temperature should be at 20 ℃, humidity is around 50%;
6) the balance correction, to the best state.
4, the correct maintenance of electronic balance should be paid attention to the problem
1) often keep indoor environmental health scale, more to keep the balance weighing room clean, once scattered items should be carefully removed in time;
2) often self-calibration electronic balance or foreign teachets regularly, ensure the balance sensitivity and so on in the groove;
3) long-term need not day at ordinary times, should collect good;
4) if the electronic balance failure, should be timely maintenance, not to work in spite of;
5) balance cannot be used overload operation, to avoid damage to the balance.
Engaged in the staff to use the scales, as long as the consideration and accomplish the above several aspects, can effectively increase the weighing accuracy, prolong the use fixed number of year of the scale, guarantee the quality of the product.
Above is the current and the entire contents of the ge teacher words lab, we will push for you all kinds of wonderful assess and articles, hoping to bring some help to your lab life
