It is mainly composed of screen box, screen frame, screen, vibration motor, motor pedestal, damping spring, bracket, etc.
1. structural components
It is mainly composed of screen box, screen frame, screen, vibration motor, motor pedestal, damping spring, bracket, etc.
1. Screen box: It is welded by several steel plates with different thicknesses. It has certain strength and rigidity and is the main component of the screen machine.
2. Sieve frame: made of pine wood or wood with small deformation, it is mainly used to keep the screen flat and achieve normal screening.
3. Screen: there are several kinds of screens such as low carbon steel, brass, bronze and stainless steel wire.
4, vibration motor: (use and maintenance methods see vibration motor instructions).
5. Motor pedestal: When installing the vibration motor, the connecting screws must be tightened before use, especially three days before the trial of the new screen machine, it must be tightened repeatedly to avoid loosening and causing accidents.
6. Damping spring: prevent vibration from being transmitted to the ground, while supporting the full weight of the screen box. When installing, the spring must be perpendicular to the ground.
7. Bracket: It is composed of four pillars and two channel steel, which supports the screen box. When installing, the pillars must be perpendicular to the ground, and the channel steel under the two pillars should be parallel to each other.
2. instructions for use
Features
1, sieve machine design, exquisite and easy to assemble, one person can operate the sieve machine.
2, alone and other related brand manufacturers, with a larger screening area and high-efficiency processing capacity..
3, unique screen structure design, convenient and quick replacement screen (only 3 to 5 minutes), in addition to this design allows the use of a variety of screens (nylon, special dragon, PP net).
4. Its mother net completely supports the fine net, so the fine net can have a long life, while reducing the use of fine net consumables and the production process of silting for a long time can reduce many costs.
Role
The basic principle is to use the heavy hammer (uneven heavy hammer) installed at the upper and lower ends of the motor shaft to convert the rotary motion of the motor into horizontal, vertical and inclined three-dimensional motion, and then convey this motion to the screen surface. If you change the upper and lower weight of the phase angle can change the direction of raw materials.
Instructions for use of motor:
When the motor meets the following conditions, it can continuously output the rated exciting force.
1. Vibration acceleration: no more than 7g(g: gravity acceleration)
2. Ambient temperature: no more than 40 ℃
3. Altitude: not more than 1000m
4. Power frequency: 50Hz
5. Altitude: not more than 1000m
6. Temperature rise: less than 80K (resistance method)
Installation maintenance
Preparation before installation
1. Check whether the motor sign conforms to the requirements.
2. Check whether the motor surface is damaged or deformed.
3, check the motor fasteners, beware of loose.
4, check the power supply, whether the lack of phase, and no-load operation for 5 minutes.
5. Check whether the rotation is flexible. If there is any abnormality, it should be excluded.
6. Measure the insulation resistance with a 500V megohmmeter. The value should be dried on the stator winding, and the drying temperature should not exceed 120 ℃.
Installation and adjustment
1, the motor should be fastened on the installation surface, the installation surface must be smooth and flat.
2. The motor can be installed horizontally.
3. Adjustment of exciting force.
4, the motor should be reliable grounding, the motor has a grounding device, the lead end has a mark, can also use the foot solid bolt grounding.
5. The motor lead wire is YZ-500V of four-core rubber cable. When connecting the power supply, the lead wire cable is not allowed to be folded sharply and is reliably fixed with the vibrating body.
Use and maintenance
1. The machine shall be equipped with electrical protection device.
2. At the beginning of the operation of the machine, check the anchor bolts at least once a day to prevent loosening.
3. When the rotation direction of the motor does not meet the requirements, adjust the power phase sequence.
4. When the machine is stopped for a long time and used again, the insulation resistance should be measured for 500 volt megohmmeter measurement, which should be greater than 0.5 megohms.
5. After the machine has been running for 1500 hours, the bearing should be checked and replaced immediately if there is serious damage.
6, the motor should ensure good lubrication, every two weeks or so to add lithium grease (ZL-3) once, refueling, through the oil cup to add the right amount of lithium grease. When sealed bearings are used, the motor is not equipped with an oil cup.
Daily maintenance
1. Before startup:
1. Check whether the coarse net and fine net are damaged
(2) Check whether the transportation support is removed
2. When starting:
(1), pay attention to whether there is any abnormal noise
Whether the current is stable
⑶, whether the vibration is abnormal
3. After use: clean up after each use
Regular maintenance
Regularly check the coarse net, fine net and spring for fatigue and damage, and whether each part of the fuselage is damaged due to vibration. The parts that need to be added with lubricating oil must be lubricated.
Installation, commissioning and commissioning
(I) installation:
Before installing the machine, first check whether the parts are complete and damaged according to the packing list.
The equipment shall be installed according to the installation drawing, and the foundation shall have sufficient rigidity and strength to support all dynamic and static loads of the vibrating screen.
3. Ensure that the screen box and hopper, chute and other non-moving parts should maintain a minimum gap of 75mm.
When installing, the four corners of the screen box should be horizontal.
(II) adjustment and commissioning:
The spring must be in a vertical state, and the contact surface between the spring upper support and the spring must be in a horizontal state. After adjustment, fix the spring upper support on the trunnion of the screen box with bolts, and then weld it into a whole.
2. The no-load test run time shall not be less than 2 hours. After the no-load test run is qualified, the load test run can be put into operation. The load test run can be carried out according to the requirements of the process test run.
