型 Old style spring + copper cake + rubber type
The rubber core I-shaped seat on the left is the piston air pump on the right.
1) I-shaped seat is external ribbed 2-inch interface: the bottom is connected to the bottom of the sand cylinder, and the bottom is connected to the 45-degree sand tee.
Built-in wear-resistant rubber core height 110 mm * diameter 45 mm * inner hole diameter 13MM / 18MM silicone material, wear-resistant.
2) Rubber pump
The original use of rubber pads and springs to control the displacement of the thimble is easy to break. If used for a long time, the rubber pads are easy to break.
灵敏度更高,关键是增加了使用寿命,更换容易,成本大大节约. The new air pump uses 2 piston rubber rings to make the ejector pin shift more smoothly. The sensitivity is higher, the key is to increase the service life, easy replacement, and significant cost savings.
3) Thickening sand tee:
Cast iron, thickened casting, the upper part is 2 inches of internal teeth (general water pipe teeth), the front is 1.2 inches of external teeth (connected to the sand cylinder connector or adapter), and the rear is 1.2 inches of internal teeth connected to the air supply pipe.
Many companies' sand tees are integrally connected to the sand valve. Once damaged, they must be replaced in their entirety. In order to save costs for customers to replace, the tees are now separated and improved.
Increase the wall thickness at the bottom and increase the wear time.At the same time, the sand drop in the tee was changed from the original 90 degrees to a 45-degree oblique angle.
减少砂粒在砂阀底部的反弹和回旋,减少少对三通和砂缸接头的磨损, Increase the effective power of the particles in the sand valve, reduce the rebound and rotation of the sand particles at the bottom of the sand valve, and reduce the wear on the tee and sand cylinder joints.
解决 喷砂过程中经常不出砂的现象,您知道么???? The most important thing is to use our inner 45 degree sand tee, which can effectively reduce or try to solve the phenomenon that sand is often not produced during the blasting process, do you know ????
Sand regulating valve sand regulating steps:
During the blasting operation, according to the blasting state, the handle on the manual control abrasive valve can be adjusted to adjust the flow of the abrasive outlet. The flow of the abrasive should not be too large.
When viewed under the sun or other bright light sources, the flow of air containing abrasives is not much different from the flow of pure air.
■ Adopting air control sand control valve to adjust sand:
If a pneumatically controlled sand control valve is used, the valve core in the I-shaped seat is closed during normal shutdown.
1) Adjust the left screw to the middle of the rubber core of the sand valve
2) Adjust the nut under the handle of the right sand control valve, and adjust it into the right beam in the I-shaped seat, so that the right beam in the I-shaped seat squeezes the rubber core to the left to the middle, and squeezes with the left beam top of the left screw. The rubber core is closed, forming a closure.
In other words, the left screw and the right nut are tightened to the valve core at the same time. When the manual control switch is pressed, the compressed air entering the sand control valve will squeeze the rubber pad of the sand control valve, causing the spring in the sand valve to contract. The thimble is retracted to the right, so that the right beam in the I-shaped seat is returned, the inner channel of the rubber core is opened, and the abrasive passes through the sand valve to form a sand blasting job.
Check the best normal state in the second and second steps above: a slight airflow from the muzzle (not a large amount of rushing out) without the grit spraying is the best effect.
3) After the above 2 steps are adjusted, the test machine works. If the spray gun still does not produce sand or the amount of sand is too large, you need to adjust the handle switch on the right side of the sand valve (behind the nut) to reduce the amount of sand clockwise. Counterclockwise is to increase the amount of sand.
When adjusting, you must make fine adjustments, one touch at a time, adjust it, and spray the sand until it is suitable.
