Tanker trailers are mainly used for large oil transportation, and the tonnage is generally around 40~60 cubic meters. Tanker trailers usually have two axle semi-trailers and three axle semi-trailers. The tanker material of the tanker trailer is made of q235a steel plate. The tank body has built-in multi-channel reinforced anti-wave baffle plate. The lower end of the baffle has through holes to reduce the impact of the oil in the tank and improve the strength of the tank. The combined tank mouth is located at the top of the tank body. There is a self-locking small cover on the large cover, and a breathing valve is installed on the upper side of the large cover to ensure uniform atmospheric pressure inside and outside the tank; with an electrostatic grounding wire. ? Install the pump oil system, take the force from the gearbox side through the power take-off, self-priming and self-discharging; with two pumping oil pipes, equipped with quick-connect fittings, suction stroke of 6 meters. Two fire extinguishers and dedicated A.
The tanker trailer is divided into two parts, the tank body and the skeleton or bracket that supports the tank. Faults and maintenance methods: 1. The brake is not working and the brake is slow. Cause: The brake shoe friction plate and the brake drum have too much clearance. The gap between the brake shoes and the friction plate is excessively worn, and the brake shoe is replaced. Replace the gas leakage of the gas chamber brake system to reduce the pressure, check the leaking part, repair or replace the parts. The emergency relay valve works poorly. Replace
2, the brake cannot be released, and the brake is released slowly. Cause: The system pressure is too low. Increase the pressure of the air brake system to the specified value. The brake return spring is damaged, the replacement spring pipe is blocked, the emergency relay valve or the quick release valve is inspected and cleared. The check and replacement of the brake chamber push rod stroke is incorrect, and the adjustment is made again. Reasons for tire swing: Loose wheel nuts, tighten the axle bearing sintered and damaged, replace the bearing axle bending, correct and replace the axle bearing clearance too large, properly tighten the bearing lock nut, and replace the bearing grease on time. Replace the axle bearing; the tire is excessively eccentric, the axle axis and the centerline of the frame exceed the standard seriously, adjust the distance between the two ends of the axle and the traction pin as much as possible. 4. The shaking resistance of the rocker is too large. Reason: poor lubrication, relubrication The grease bearing is damaged, the replacement bearing gear is eccentric or the wear is serious, and the screw of the screw of the replacement part is broken and checked, and the screw is replaced.
