First, the grouting machine grouting preparation before 1, check the grouting machine power is normal.
2, check the motor and gear oil pump, and perform a few revolutions.
3. Turn on the pressure gauge switch and release the relief valve to adjust the pressure handwheel.
4. Put the suction pipe into clean water for testing.
5, check the motor and gear pump steering direction is correct.
6. Check whether the hydraulic reversing valve block can control the reciprocating motion of the cylinder.
7, start the motor, the system pressure is adjusted to 1 ~ 2Mpa, commissioning for about 5 minutes (at this time the mixer filling valve is fully open), if it is operating normally, the valve on the mixer is closed, the oil pressure is adjusted to the need The maximum pressure then stops the grouting machine and prepares for formal work.
Second, the official grouting machine grouting process 1, open the mixer grouting valve, the first injection of water for 1 minute.
2. If everything is normal, the two suction pipes should be put into the slurry tank quickly to implement normal grouting operation.
3. Each time grouting is completed, if the grouting is not continued, the two suction pipes should be immediately transferred to the clear water tank to clean the remaining slurry in the grouting machine to prevent the slurry from solidifying over time and increase unnecessary troubles.
4. After the working cylinder and inlet and exhaust valve body are cleaned, the suction pipe shall be taken out from the water, and the grouting machine shall be further started to drain the remaining slurry in the working cylinder and the intake and exhaust valve body, and then cut off the power.
Third, note the operation of the grouting machine 1, reciprocating grouting machine should be placed as far as possible in a horizontal position, to avoid distortion of the tubing, suction pipe, discount, suction pipe as possible to shorten the vertical distance of not more than one meter .
2. Regularly check the fuel tank network and the oil filter, clean it, and regularly replace the hydraulic oil. It is recommended to replace the hydraulic oil once a month or so. Use hydraulic oil No.46 in summer and No.32 hydraulic oil in winter, about 45 kg per hydraulic oil change.
3, the work site should have sufficient water to facilitate work.
4, the hydraulic joints should be checked regularly and shall not be loosened.
5, the construction operator must have a certain grouting experience in order to ensure smooth construction operations.
6, the electric control box, motor and electrical appliances should be kept clean and dry, and often check the above parts of the conductor shall not be damaged to prevent leakage.
7. When carrying the grouting machine, do not have large bumps, and do not arbitrarily beat the components of the grouting machine.
Fourth, the maintenance of Glue grouting machine 1. If the grouting machine is no longer used in the near future, the intake and exhaust valve body and the working cylinder should be disassembled, cleaned, brushed with anti-rust liquid or grease, and then assembled for use.
2. Removal method: Remove the inlet and exhaust valve body. Remove the two nuts on the end screw of the working cylinder and remove the cylinder head and the cylinder barrel. Do not damage the seals when disassembling.
Elevator modernization (or lift modernisation) is the process of upgrading the critical parts of the elevator in order for it to be able to handle new technology, have better performance, improve safety, and even give the aesthetics an up-to-date appeal
Most elevators are built to provide about 20 years of service, as long as service intervals specified and periodic maintenance/inspections by the manufacturer are followed. As the elevator ages and equipment become increasingly difficult to find or replace, along with code changes and deteriorating ride performance, a complete overhaul of the elevator may be suggested to the building owners.
A typical modernization consists of controller equipment, electrical wiring and buttons, position indicators and direction arrows, hoist machines and motors (including door operators), and sometimes door hanger tracks. Rarely are car slings, rails, or other heavy structures changed. The cost of an elevator modernization can range greatly depending on which type of equipment is to be installed.
Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment to conform to current codes.

Benefits of elevator modernization
Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment (such as double brake system, unintended car movement protection device on the brake system etc.) to conform to current codes.
