The semi-trailer oil tanker is divided into two parts, the oil tank part and the frame supporting the tank body or the driving part. The rear part of the semi-trailer oil tanker is generally the same, with rear double axles (two axles) and rear triple axles (three axles). The traction head is selected according to the needs. Semi-trailer oil tankers are usually called by the brand of the traction head.
The tank body is made of 4mm or 6mm high-quality carbon steel produced by the steel company according to national
standards. The shape is divided into elliptical or square round tank bodies, which can hold 1-4 kinds of oil products. Heating and insulation series tank bodies can also be produced. Alcohol and chemical tankers are made of imported stainless steel with a thickness of 4mm-5mm. Various types of hydrochloric acid, sulfuric acid, and alkali liquid tankers are made of plastic with a thickness of 12mm-22mm. There are multiple wave-proof partitions in the tank body. High-pressure gas leak detection is used.
Oil transport semi-trailers are mainly used for large-scale oil transportation, and the tonnage is generally around 40~60 cubic meters. Oil transport semi-trailers usually include: two-axle semi-trailers and three-axle semi-trailers. The square tank body of the oil tanker semi-trailer is made of q235a steel plate. The tank body is built with multiple reinforced wave-proof baffles. There are through holes at the bottom of the baffles to reduce the impact of the oil in the tank body during driving and improve the strength of the tank body. The combined tank mouth is located at the top of the tank body. There is a self-locking small cover on the large cover. A breathing valve is installed on the upper side of the large cover to ensure that the atmospheric pressure inside and outside the tank is consistent; with an electrostatic grounding wire. ? Install an oil pump system, which takes power from the gearbox side through a power take-off, and can be self-priming and self-draining; with two oil extraction pipes, equipped with quick-release connectors, and a suction range of 6 meters. Two fire extinguishers and special A. The oil tanker semi-trailer is divided into two parts, the oil tank body and the frame or bracket that supports the tank body.
Faults and repair methods:
1. Braking is not effective, braking is slow? Reason: The gap between the brake shoe friction plate and the brake drum is too large, adjust the gap. The brake shoe friction plate is excessively worn, replace the brake shoe friction plate. The air chamber is damaged, replace the air chamber. The air brake system leaks and the pressure drops. Check the leaking part, repair or replace the parts. The emergency relay valve is not working properly, replace it.
2. Tank semi-trailer Export tank truck Structure details The brake cannot be released, and the brake is released slowly. Reason: The system pressure is too low, increase the air brake system pressure to the specified value. The brake return spring is damaged, replace the spring. The pipeline is blocked, check and clear the emergency relay valve or quick release valve. Check and replace the brake air chamber push rod stroke is incorrect, readjust it.
3. Reasons for tire swing: loose wheel nuts, tighten axle bearings, sintering, damage, replace bearings. Axle bending, correct, replace axle bearing clearance is too large, properly tighten bearing locking nuts, replace bearing lubricating grease on time, replace axle bearings; tires are excessively worn, the verticality between the axle axis and the center line of the frame is seriously marked, adjust the distance between the two ends of the axle and the traction pin as much as possible.
4. Reasons for too much resistance to the crank: poor lubrication, add lubricating grease. Bearings are damaged, replace bearings. Gears are eccentric or severely worn. Disassemble and check to replace parts. Screw thread is damaged, replace the screw.
