How much is the two-floor small household elevator?
There are many factors affecting the price of domestic elevators, such as brand, configuration, etc.
1) Brand. First-line brands must be more expensive, no doubt.
2) Configuration. Such as host, control system, door operator, speed limiter, safety gear, car, car door, landing door, etc., these components will also directly affect the price of the elevator.
3) Shaft. The elevator shaft is mostly made of steel structure, and the cost is generally about 25000; Of course, there are also aluminum alloy sightseeing shafts, which are more expensive, and the price is about 50000 yuan.
1. The phase sequence of the input power supply is wrong or the phase loss causes the phase sequence relay to act.
2. The elevator is overloaded or blocked for a long time, causing the thermal relay to act.
3. The foot rope break switch acts. The governor rope can be protruded or lengthened.
4. Limit switch action caused by elevator punching or sedimentation.
5. The overspeed of the governor will cause the governor switch to act.
6. Safety clamp action. Find out the cause. The overspeed action of the governor, the misoperation of the governor oil loss, the oil loss of the ruler and rope pulley, the involvement of foreign matters in the ruler and rope pulley, and the safety check block interval may be too small.
7. When each switch is normal, check whether the contact is in good condition and whether the wiring is loose.
8. The safety window support causes the safety window switch action.
9. Some emergency stop switches may be pressed.
10. At present, many elevator safety circuits are normal, but the safety relay is also absorbed, but the frequent contact is usually taken out of the safety relay and sent to the computer for detection. Poor contact of the safety relay itself will also cause safety circuit failure.
