Machine selection and use skills

Operating instructions. Operation skills of shot blasting machine. Common faults and treatment methods of drum shot blasting machine, etc
(1) How to distinguish the quality of shot blasting machine?
1. Whether the appearance is exquisite and whether the paint spraying is meticulous.
2. Whether the processing of guard plate, blade, impeller, directional sleeve and shot dividing wheel is meticulous.
3. Whether the shot blasting effect and efficiency can achieve the expected effect.
4. Whether the service life of damaged parts can meet the industry requirements.
(2) Installation skills of shot blasting machine
All shot blasting machines shall comply with the following rules during installation:
1. Host in place: when the host is in place, its levelness and weight must meet the requirements of the drawing.
2. The installation of parts shall be carried out from bottom to top.
3. Rail type, catenary type and roller type shall be from the inside to the outside of the equipment.
4. During commissioning, partial pre commissioning shall be carried out first, and then full operation shall be carried out after normal operation.
(3) Operation instructions for shot blasting machine
The operator must pay attention to whether the instrument display of the electric cabinet is normal during the operation of the equipment.
1. All personnel entering the shot blasting room must wear goggles and safety helmet.
2. The operator must inspect the equipment every day. Including: lubrication part and mechanical part.
Lubrication parts such as reducer, hydraulic, oil mist and bearing chain.
Mechanical parts, such as the wear of rotating parts and wearing parts. The wear condition shall be registered every day, and the vulnerable parts shall be replaced in time.
For example, if the shot blasting device vibrates, it must be shut down immediately to replace the blade.
3. The lubricating part shall be lubricated in time.
4. The orientation sleeve must be adjusted and replaced in time.
5. Check whether the steel shot quantity is sufficient every day.
(4) . usage skills of shot blasting machine
1. In the process of shot blasting, more workpieces should be placed in the blasting area as much as possible, which can not only improve the cleaning efficiency, but also reduce the wear of the guard plate and increase its service life.
2. When the workpiece cannot be increased, the orientation sleeve shall be adjusted to make the shot steel shot on the workpiece as much as possible, which can also increase the service life of the guard plate and reduce its wear.
3. ① the dust removal system shall adjust the gates at each branch pipe to make the wind distribution reasonable and enhance the dust removal effect. ② The dust collector shall ensure regular ash cleaning.
(5) The common faults and treatment methods of drum shot blasting machine are as follows:
Problem 1: insufficient steel shot
Performance: long cleaning time, poor effect, low efficiency and serious damage to the guard board.
Treatment method: add an appropriate amount of steel shot (measure the current of shot blasting motor with clamp ammeter to reach the rated current).
Problem 2: the shot blasting gate is incorrect (the position of the directional sleeve window is incorrect).
Performance: long cleaning time, poor effect, low efficiency and serious damage to the guard board.
Treatment method: adjust the position of the directional sleeve and window to throw it under the door cover, about one-third of the door cover (Trial throwing with wood board or paper shell).
Problem 3: the drum does not rotate
Performance: the cylinder does not rotate, the supporting wheel is still running, the supporting wheel is seriously worn, and the cylinder track is worn out.
Treatment method: check the loading amount of the workpiece and do not exceed the required weight. Check whether there are foreign matters or workpieces in the frame that block the drum.
Problem 4: drum deviation
Performance: there is gnawing on the inner ring of track and supporting wheel, and the track is damaged.
Solution: adjust the top screw of supporting roller bearing seat to make the drum run under normal conditions.
Problem 5: poor dust removal effect
Performance: the equipment has dust leakage.
Treatment method: check whether the dust discharge cover at the lower part of the dust collector is closed and whether the wind wheel has been seriously worn.
