Pressure balanced subsea valve for multi-tank tank truck

August 13, 2021

Together with the electrostatic grounding device can not be put on, the tanker must strictly follow the standard, the device is indeed, on schedule inspection. Assuming that the oil leakage can't be eliminated, the damping rod should be pulled out. If there is a difference in the card issuing or severity, check whether the gap between the piston and the cylinder is too large, and whether the shock absorber piston rod has any zigzag. Are there any scratches or scratches on the outside of the connecting rod and the cylinder bore? Hairline hoses are prohibited from using non-conductive polyethylene hoses as oil pipelines, and plastic containers are prohibited when handling oil products. For the current use of clamps and magnetic joints grounded, should not be randomly caught or adsorbed in the tank parts, or even the appearance of the paint. These are the basic safety knowledge. This is a helium gas for the antistatic electrode, and it is a big danger.
It is necessary to use equipment that meets technical standards and safety requirements.
First, check whether the shock absorber of the oil tanker is leaking oil; make the car park on the road with poor road conditions for 10 km, park it, touch the housing of the shock absorber by hand, assume that no heat is applied, and clarify that there is no resistance inside the shock absorber. The resonator does not operate.
The oil seal gasket and the seal washer broke, and the storage cylinder cover nut was loose. The auto control, remote control, metering instruments, valves and other equipment of the oil delivery station must be overhauled and calibrated as scheduled, and an associated management system should be formulated, especially for the raw materials of the oil distribution equipment. At this moment, can participate in the appropriate lubricants, and then experiment, if the shell fever, the tanker is the lack of oil within the shock absorber, should add enough oil, if found to leak, first tighten the nut of the cylinder head, if the shock absorber is still If the oil leaks, the oil seal and the gasket may be damaged and the new seal should be replaced.
When the truck moves slowly and brakes in an emergency, if the car vibrates more violently, clarified that the shock absorber has a title, remove the damper and erect it, and clamp the lower end joint ring on the vise, and then pull and dampen the vibration. The rod should be blocked several times. At this moment, there should be unrestrained resistance. The resistance of the tanker to pull up should also be greater than the resistance to downward pressure. If the resistance is not disorderly or non-resistance, it may be the lack of oil inside the shock absorber. Or if the valve parts are damaged, the parts should be corrected or replaced. After determining that the shock absorber has a title or has failed, it should first check whether the shock absorber is leaking oil or there are traces of old oil leakage.
