FAQ

How many kinds of elevator safety tongs?
Types of safety tongs:The elevator safety gear according to the braking element structure can be divided into different wedge type, eccentric wheel and roller type three, according to the braking deceleration (braking distance) can be divided into different instantaneous and incremental two.
What do you mean by sub-pixel mapping and blocking output in the VR panel?
However, if it's a general TGA or JPG format, it doesn't matter if you don't tick it. Sub-pixel mapping, when it comes to sub-pixel mapping, refers to sub-pixel sampling, which is done during sub-pixel sampling, which avoids aliasing when color mapping occurs, such as black pixels.
Lift progressive safety pliers concept
Progressive anti falling safetydevice action to the final stop for a short distance, the braking force increased gradually (to eventually stop action finally stopped falling a distance not greater than 1.4 meters). Progressive; anti falling safetydevice buffering performance, impact load generated by braking is small, less adverse effects on the structure and the transmission system, the crew produced small physiological and psychological effects, so as to be manned the construction elevator equipment must be installed progressive anti falling safetydevice.Personal recommendations: the use of progressive anti falling safety device, I remember a name: Kim Erhui brand is good, the price is also possible!
How can the elevator speed limiter and the safety tongs be linked together?
Elevator speed limiter, safety gear test is an important test of elevator acceptance inspection and regular inspection shall be required, the car uniform layout of the corresponding load in the engine room human action speed limiter, control elevator to flat layer or the maintenance of speed running down, the speed limiter of electric switch action. Then, short speed limiter and safety clamp, electrical switch, brake the speed limiter steel rope, then lift the safety tongs device, clamp the guide rail, and stop the car.
What is the output current of the inverter to be measured? Why not use the current clamp meter?
Personal recommend the use of AnyWay variable frequency power test system, its wide frequency, wide width value, phase measurement, suitable for arbitrary waveform modulation mode, voltage current bandwidth of 30KHz, bandwidth of 20KHz, the highest sampling frequency of 250kHz, fully meet the requirements of measurement of variable frequency power, full range accuracy, is currently the only one high precision frequency measurement equipment. In particular, the introduction of the ATITAN frequency conversion power standard source, but also to fill the gap at home and abroad, you can also look at the relevant news online, a lot of reports in this regard.
What's the use of car calipers?
A disc brake on a car consists of a brake pump, a brake disc attached to the wheel, and a brake caliper on the disc. When braking, the high pressure brake oil pushes the piston in the caliper and presses the brake shoe to the brake disc to produce braking effect. Disc brake, it is divided into ordinary disc brake and ventilated disc brake two kinds. Ventilated disc brake is set aside a gap between two pieces of brake disc, the gas flow passes through in the space, some ventilated disc also drill out many circular vent on disk, or the disk is in the cut out of the tank ventilation or precast rectangle hole. The ventilated disc brake uses the airflow function, its cold heat effect is better than the ordinary disc brake. The main advantage of disc brakes is that they can be braked quickly at high speeds. The heat dissipation is better than the drum brakes. The braking performance is constant, and it is easy to install advanced electronic equipment such as the ABS.
How to use a measurement of three phase current
1. First, select the voltage level of the clamp type ammeter correctly, check whether the insulation is good, whether it is damaged or not, whether the pointer is flexible, whether the jaw is rusted or not. The rated current is estimated according to the motor power to select the range of the meter.2, in the use of clamp ammeters should carefully read the instructions, it is AC or AC / DC clamp meter.
How do I do the elevator speed limiter safety test?
Because the elevator speed limiter and safety clamp belong to a complete set of linkage, it is often called safety linkage test. The speed limiting device belongs to an action triggering mechanism, and the safety clamp belongs to an actuating mechanism.
