Regularly maintain the sealing strip of automatic feeding mixer truck:
The automatic loading and welding of the small mixer door are actually stuck to the sealing strip, which is also the operation to ensure the sealing. Otherwise, these gaps are simply filled with wind blown sand particles outside, causing corrosion, etc. Check the seal of the small mixer for large cracks. Today, I want to share with you the daily maintenance of the sealing strip.
1. Check whether the seals of the automatic feeding mixer have large cracks. If the seal is broken, it can be corrected with adhesive. In particular, the use of adhesives on seals can easily fill large crack areas. Of course, if the seal is seriously damaged or greatly aged, please replace it with a new one.
2. After the driver cleans the door and window sealing strip with concrete mixed detergent, a layer of penetration protective agent shall be applied to avoid the aging of the sealing strip and significantly improve the sealing effect of the sealing strip. In addition, the gap between the sealing strips is easily filled with dust and rust. To do this, you need to use a brush to remove the dust.
3. When replacing the whole fuselage, it is necessary to apply a layer of sealant on the stacked part of the welding part. The thickness of the adhesive layer is about 1mm, and the adhesive layer is free from improper adhesion, bubbles and other defects. The whole bottom surface of the floor and the bottom surface of the front wheel cover shall be coated with 3mm-4mm elastic coating and anti-corrosion coating. These measures not only significantly improve the sealing function of the body, slow down the corrosion rate of the body, but also greatly improve the ride comfort.
4. Sealing door and body is a relatively difficult part. The sealing requirements are relatively strict. The part to be sealed is relatively long, the cross section shape of the part to be sealed is different, and the door is often opened and closed. Install the three-way and four-way sealing gasket on the concrete mixer truck, and install the four-way sealing structure of the front pillar and the top beam side beam. This type of multi-channel seal is generally placed in the gap between the front doors. In addition to its sealing function, it also has the effect of reducing vehicle noise.
5. After the window glass is damaged, the driver should check whether the sealing strip is damaged when replacing the glass. In addition to being able to easily pull up and lift up the window glass, attention should also be paid to the sealing around the window glass, because the window will not generally return to its original shape after maintenance. If the gap between glass and glass groove is uneven, the rubber strip has poor contact between glass and glass groove, so the driver can easily pull the seal ring by hand.
6. When replacing the roof, the driver shall press fit and apply a layer of conductive sealant around the roof. After welding, apply curling adhesive on the launder and joint. This is not only good for the body. Seals can avoid premature corrosion caused by water accumulation in flange welds.
7. The skylight of automatic feeding mixer is the basic configuration of most family cars. When you open the sunroof of the car, the rubber sealing guide rail will be exposed to the air, which will inevitably accumulate dust, even into small gravel. After long-term use, the sunroof may be deformed due to wear, and the water drain may be blocked.
Although the sealing strip is only a small part of the body, it can ensure the stability and weight of the door, protect the interior from the impact of wind, rain, dust, heat and noise, and can decorate the edges of the door and windows. When the body is vibrating or distorted, the sealing strip can also be used as a shock absorber and shock absorber to protect the glass. Therefore, the maintenance of concrete mixer is not a simple matter, and the connection can not be ignored.
