1. Adjustment: The working clearance between stirring Blade and stirring pot has been adjusted to 3±1mm before leaving the factory. Adjust the working gap between stirring blade and stirring pot, loosen the adjustment nut (15), rotate the stirring blade to move up and down, and then use the detection rod to detect the correct clearance, then tighten the adjustment nut (15).
JJ-5 cement mortar mixer maintenance:
(1) The work site should be kept clean. After each use of the JJ-5 cement mortar mixer, the residual mortar inside and outside the mixing blade and the stirring pot should be completely removed, and the mortar and dirt on the scattered and splashed machines should be cleaned and dried. Afterwards, put on the shield to prevent dust.
(2) The machine has no external filler hole. The worm gears, gears, bearings, and other moving parts of the transmission box are greased once every quarter. When refueling, open the upper cover, and then open the transmission case cover. Between the support and the column guide rails, the lifting mechanism should often drop Into the oil lubrication, maintenance once a year, all the JJ-5 cement mortar mixer to clean and add lubricants and grease.
(3) If metal impact noise is encountered during operation of the machine, first check that the clearance between the stirring blade and the stirring pot is correct.
(4) When using a stirring pot, gently handle it and do not arbitrarily collide so as to avoid deformation of the stirring pot.
(5) Electrical insulation should be checked frequently. Cold insulation resistance ≥ 5MΩ at a temperature of 20°C ± 5°C relative humidity of 50% ~ 70%. Cement mortar mixer operation and use Plug the machine's power plug into the power socket and turn on the power. The red indicator light is on to indicate that the power is on. Insert the plug of the programmer into the socket of the program controller. The digital display of the program controller is 0, and the sand tank ( 4) Load 1350g standard sand, mix 225g of water and 450g of cement in the stirring pot (17). Place the stirring pot (17) into the positioning hole of the holder (18). Turn the pot clockwise until it locks, and then pull the handle ( 22) Move the stirring pot (17) upwards in the stirring work positioning position. JJ-5 cement mortar mixer electrical operation manual and automatic two kinds 1, automatic: turn the rotary switch 1K to the automatic position, press the programmable controller start button, which automatically completes a low speed for 30 seconds - then low speed for 30 seconds, at the same time Automatic sanding - high speed 30 seconds - stop 90 seconds - high speed 60 seconds - stop the rotation of the work process. The entire process 240 seconds ± 1 second. Then, pull the handle (20) to move the stirring pot (17) downward, turn the stirring pot (17) counterclockwise to the release position, and remove the stirring pot.
JJ-5 cement mortar mixer structure: Manual: Turn the knob switch to the manual position, the machine is rotating, according to the test needs, can be arbitrarily controlled low speed and high speed rotation time, slow turn control sand time early and late ,length. Toggle switch 2K controls low speed and high speed, 3K controls sanding and stops sanding. Note: The socket three-phase power supply wiring must ensure that the direction of the blade revolution is the same as the direction marked on the machine body, otherwise, the stirring mechanism may be easily damaged. If the direction is opposite, any two-wire three-phase power line can be reversed.

The screw driver is a common tool used to turn the screw to make it in place. It usually has a thin wedge head, which can be inserted into the slot or notch of the screw head.
There are mainly one character (minus sign) and cross (plus sign). There are also common hexagon screw drivers, including two kinds of hexagon and hexagon. Each screw driver has different specifications and can be customized.
According to different head types, screwdrivers can be divided into one character, cross, meter character, star (computer), square head, hexagon head, Y-shaped head and so on. One character and cross are the most commonly used in our life, such as installation and maintenance. It can be said that as long as there are screws, screwdrivers will be used.
Hexagonal head is not used much, commonly used in the hexagonal wrench, such as some machines a lot of screws are with hexagonal hole, convenient for multi angle force. We don't see many big ones. Small ones are often used to repair mobile phones, hard disks, notebooks and so on. We call small screwdrivers clock batch. We often use star T6, T8, cross pH0, ph00 and so on.
