How To Correctly Use Shotcrete Machine

1) Before class jet, to check the pressing force applied to the rubber combined board. Clamping force is too small, it will create pressure air from the joint surface to escape. It carries the fine particles into the closed surface, combined with increasing rubber liner plate and rotor wear. Clamping force is too large, it will cause increased wear rubber combination plates and motor power consumption increases.
2) The class work is completed, the cleaning of the machine at the same time, especially to rubber liner combination plate and rotor surfaces clean. And check for wear rubber liner combination plate and rotor
(1) the degree of wear plate rubber combine to whether confined to achieve effective measure. In case of gas high and low range can not be isolated and sealed surface has deep grooves, rubber combined board must be replaced.
(2) rotor liner surface may not have deep scratches. Scratch deeper than 1mm need to re-grinding. Rotor liner over the edge of the orifice must be kept sharp edges. Fine particles can penetrate the rubber combined with the rotor combine panel lining, causing increased wear rubber combination plate, thereby shortening its life if the edges are bevelled at work. Therefore, it is timely grinding rotor liner.
2. rubber material of the rotor body cavity and the discharge port drogue maintenance
Rubber material of the rotor body cavity and the sleeve material with anti-adhesive materials, without bond under normal circumstances, but should be opened after the end of each class and the material of the rotor body sleeve, check whether there is material to be deposited and cleaned.
3. The main drive gearbox maintenance
1) class should be cleared up after work surface adhesion of mixing materials and other debris.
2) class before starting the deceleration observed inside the oil level should be insufficient to replenish.
3) When the gearbox working temperature shall not exceed 60 ℃, should not have abnormal vibration or noise. Otherwise, inspection and maintenance should be carried out.
4) the cumulative work 250 hours change the oil.
