Vacuum pump exhaust valve is not working properly, will naturally greatly affect the degree of vacuum, vacuum pump exhaust valve repair is crucial. Today Xiaobian sorted out vacuum pump exhaust valve repair steps. 1, when dismantling, first pump oil let go part of the oil surface down to below the oil window. 2, open the oil windows, remove the valve (or valve bowl, ball), check whether they are intact, smooth, flexible No, the assembly is solid, suitable, pin hole no. 3, usually the valve should be able to cover the vent very smooth. 4, the large pump valve plate is mostly steel, is compressed by the spring, the valve should be checked for damage, the spring is hard to cause the valve is difficult to beat. 5, oil-resistant rubber valve type is to check whether they are deformed. Single Containment LNG Storage Tank
A single containment LNG tank
design is defined as a tank comprising an inner tank and an outer container
designed and constructed so that only the inner tank is required to meet the
low temperature ductility requirements for the storage of the product. The
outer container of a single containment storage tank is primarily for the
retention and the protection of the insulation and to constrain the vapour
purge gas pressure, but is not designed to contain the refrigerated liquid in
the event of a leakage from the inner tank, i.e. it will collapse due to
brittle fracture when getting in contact with large quantities of cryogenic
liquid leaking from the inner tank. Therefore a single containment LNG tank
needs to be surrounded by a bund wall or dike in order to prevent uncontrolled
liquid spillage. It is also referred to as a double integrity LNG container
since the bund wall is considered a second barrier.
Doer's single containment
storage tanks have a capacity of 200-50,000 m3 and pressure of 10-50 kPa.
