The lamp cap refers to the interface that is connected to the end of the lamp line for mounting the lamp, and should be used with caution. So, what should you pay attention to when buying a lamp holder? Let's take a look at it with the Ko Jiaju.com.
Pay attention to the following points when buying a lamp holder:
The first point: the rated current value of each lamp head is different, so choose the appropriate lamp head according to the actual situation. Avoid the use of the lamp cap because the bearing capacity is too small, causing the lamp cap to burn or be damaged.
The second point: pay attention to the maximum voltage that the lamp cap can bear. The maximum voltage of the selected lamp cap is greater than the voltage of the actual circuit, so as to ensure normal use. Avoid problems such as short circuit and burnout during use.
The third point: pay attention to the insulation resistance when buying the lamp holder, so it is best to choose the insulation material when buying the lamp holder, do not buy metal material.
The fourth point: the quality of the contacts in the lamp head will directly affect the use, so it is best to choose a lamp cap with a small contact resistance, so that it can be used normally and can guarantee the service life.
Fifth point: In order to protect the service life of the lamp holder, different types of lamp holders should be selected according to the occasion of use. If the power is small, consider the mechanical life of the lamp when purchasing. In the case of high power, the life of the lamp head should be considered when purchasing.
The most important thing to buy a lamp is the safety issue. If the lamp is not guaranteed, it will be dangerous at the time. The price of the lamp holder is not high, so don't bring a big hidden danger because it is cheap and cheap. For more information, please stay tuned for the tracking report of Xiaojiaju.com.
Zhejaing Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Meter, Mass Flowmeter, Mass Meter, Flow Meter, Flowmeter, ATEX, IECEx & CE approved. The product range covers different size from DN03 to DN150, and bigger sizes are being developed.
Sealand mass flow meter is designed and produced according to world`s latest Coriolis technology with exelent appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
