(1) electric lock function: a layer of call box equipped with electric locks, for the temporary start and close the elevator control system; (2) delay protection: when the normal running time, the elevator automatically stop running (3) fault self-display function: when the elevator is faulty, the fault will be diagnosed after the code in the form of digital display in the control cabinet; (4) fault self-diagnostic function: when the elevator (5) self-recovery insurance function: control signal loop if the short-circuit insurance automatically disconnect, when the failure to eliminate the insurance automatically connected; (6) contactor stickers to keep regular light (such as the existence of a fault, can diagnose the phenomenon and cause of failure; (7) call response function: press the call button, the call layer button to be activated (if the contact button is not broken, Digital indicator light, after the station to cancel the memory indicator off; (8) beep prompt function: with a station beep prompt function;

Q:My model: hippocampus Fumei to transmission: manual Displacement: 1.6 l Driving range: 2200 km Time of purchase: September 2017 Problem Description: Ask the experts advise on the three generations of the first solution of the United States to the oil 4S there are two kinds of oil, one is mineral Oil 10W-30 The other is semi-synthetic 5W forged teeth forged forging feathers Quan Chuan Huowen these two are SL level. Compare the favorite Castrol's EDGE5W-304 lift. Other do not know. In fact, they also know that economic cars do not need to use a good oil, but still want to own the first car a little better ~ by the way here we winter temperature is generally not lower than minus 25 degrees. Road more urban areas, and occasionally run suburban road. Seek expert advice ~! More

Semi-synthetic 5W-30 to meet your needs, semi-synthetic 5000 a security has been very extravagant

Q:You brother ah, sister who can give me a complete waterproof construction program, the basement roof with polyurethane, kitchen and toilet with JS, thank you friends

Can be downloaded from Google, these two materials approach is very simple and very common.

Q:This is a question, who can give a full answer

The elevator was broken for the first time to repair, each time to do maintenance must check to confirm the elevator is safe, and finally signed a good maintenance

Q:Hitachi Elevator out of the 61 with the door of the lock after the opening of the arrow outside the instructions to flash how to repair

May be caused by the connection of the motherboard. May be caused by damage to the internal parts of the machine. It is recommended to contact the maintenance staff can be repaired. An elevator is a motor-powered vertical lift with box-like pods for multi-storey construction or cargo. There are steps, stepping board mounted on the track for continuous operation, commonly known as escalators or automatic sidewalks. Serving the floor of the fixed lifting equipment. The vertical lift elevator has a car running between at least two rows of rigid or inclined rails with an inclination angle less than 15 °. Car size and structure to facilitate the passengers access to or loading and unloading of goods. It is customary to use the elevator as a general term for vertical traffic in a building, regardless of the way it is driven. According to the speed can be divided into low-speed elevators (1 m / s below), fast elevators (1 ~ 2 m / s) and high-speed elevators (2 m / s or more). The mid-19th century began to appear hydraulic elevator, is still in the low-rise buildings on the application. In 1852, the United States E.G. Otis developed a wire rope lift safety lift. 80 years, the drive device to further improve, such as the motor drive through the worm drive winding reel, the use of balance weight and so on. At the end of the 19th century, the use of friction wheel drive, greatly enhance the lift height of the elevator.

Q:What are the electrical parts of the elevator and what are their roles?

The control system (including the main board, car plate, instruction board, layer display board) is responsible for the elevator start, run and stop. Flat sensor: elevator leveling detection switch; door machine system (including door and door machine frequency converter): responsible for the elevator door. 2, safety touch panel and light curtain: car door entrance security protection; 3, limit switch: forced elevator stop of the terminal switch (in the bottom and the top of the set), the safety of the system, 4, the buffer: the roof of the elevator and the end of the end of a protection switch. Drag the system: traction machine, inverter, etc. to provide elevator running power;

Q:Grocery elevator is always automatically anti-leveling what is the reason

There are two reasons: 1, the master set the problem, the general control of the general options, when the stop after the automatic return to the base station, this time can be set. 2, the normal operation, the elevator automatically back to the base station to correct the pulse. It is not good to be your flat board, or it is not vertical. Resulting in pulse is not allowed, so the need for correction pulse. Elevator has automatic correction of the pulse function, for security reasons, the correct floor are generally in the bottom, that is, the base station.

Q:Our factory production of gears running noise, want to solve through the grinding method, seeking expert guidance. Question added: We used this method, because we buy grinding machine financial capacity is not realistic, and occasionally heard the gear grinding the processing method, they have tried, is to match the two gears to exert a certain pressure on the grinding sand bite A few minutes, after the experiment found to be able to improve some, but now our process is not good to control the angle of the helical gear, seeking expert detailed instructions, or what better way to solve our helical gear noise problem? More

This mainly depends on the gears used in what machinery and the hardness of the gear itself. If the accuracy of the gear itself is 7 or more and grinding is the finishing method, it is necessary to consider the small letter tolerance group, usually base section or tooth profile and other problems, first measure base section, such as base section need to pass through the improvement Tooth surface roughness to noise reduction; if the hobbing for the finishing method, the best plus grinding can be resolved. In addition, the parallelism of the two bearing holes can also cause tooth contact to produce noise.
