The hook type shot blasting machine is disassembled and disassembled into several parts after installation and debugging in the production plant and transported to the user’s site for installation. After the second pouring, the nuts of the anchor bolts can be fastened after solidification. After the chamber body is fixed, the work of each part can be installed. The following introduces the precautions for the installation and debugging of the relevant components.
1. Shot blasting machine:
The shot blasting machine of the hook type shot blasting machine has been installed on the chamber body before leaving the factory. Before using it, pay attention to the problems to be debugged. Check whether the fixed position of the blade, the pellet wheel, the directional sleeve and the guard plate is accurate and firm, and jog the power on to check whether the rotation direction is correct. Then adjust the position of the opening of the directional sleeve. In theory, the angle between the front edge of the directional opening and the front edge of the blade throwing position is about 90. After fixing the position of the directional sleeve, the position of the ejection belt can be detected. The method is to hang the Place a steel plate or wooden board on the position of the workpiece facing the outlet of the hook type shot blasting machine, start the shot blasting machine, put a small amount (2-5kg) of projectiles into the shot pipe, and then stop the machine to check whether the hit position on the steel plate is suitable. If necessary, such as closing the window of the partial adjustable directional sleeve downward, and vice versa, until it is suitable, and note down the position of the directional sleeve as a basis for changing the directional sleeve in the future.
2. Hoist and screw conveyor:
First carry out the no-load test of the hook type shot blasting machine to check whether the running direction of the lifting bucket and the screw blade is correct, then tighten the belt of the hoist to an appropriate degree of tightness to avoid deviation, and then carry out a load test to check the hook type Check the operation and conveying capacity of the shot blasting machine, whether there is any strange noise and vibration, and check and remove obstacles.
3. Pill sand separator:
First check whether the shutter of the hook type shot blasting machine is flexible, then check that the position of the cooking plate is moderate, and then when the hoist is debugged under load, steel shot continuously flows in, and when the hopper is unloaded, check whether the steel shot flows out in a flow curtain. fall.
Five points for the test run of the hook shot blasting machine:
The hook type shot blasting machine should pay attention to five points during the test run, which are as follows:
1. Carefully check whether the various parts of the machine are firmly connected;
2. Lubricate in accordance with the requirements of Part VI of this manual;
3. No-load test run for 2 to 3 hours;
4. If no problem is found in the above steps, open the elevator and screw conveyor, and add about 600Kg of new projectiles into the equipment from the door of the cleaning room. These projectiles are transported by the screw conveyor and lifted by the elevator, and finally stored in the hopper at the lower part of the separator. After driving, these projectiles will flow into the shot blasting machine through the electric shot supply gate valve at the lower part of the hopper, and blast the workpieces to be cleaned in the cleaning room.
5. When adjusting the shot blasting wheel, attention should be paid to the position of the directional sleeve of the shot blasting wheel so that the projectiles are all covered on the workpiece to be cleaned, otherwise the cleaning efficiency will be affected. The position of the directional sleeve window. When installing, a piece of wood can be painted with black ink or a piece of thick paper can be placed, placed at the position of the workpiece to be cleaned, the shot blasting machine is started, and the shot blasting machine is manually added to the feeding tube of the shot blasting machine. For a small amount of projectiles, check the position of the ejection belt. If the position of the ejection zone is incorrect, adjust the directional sleeve to obtain the ideal position. After the directional sleeve is adjusted, the load test can be carried out. After 30 minutes of shot blasting, the 400Kg projectile is added.
