Description

Известны способы гидравлических и стендовых испытаний насосов, гидромашин, гидроарматуры и другого гидравлического оборудовани , по которым испытани  провод т на жидкости,  вл ющейс  рабочей дл  данного вида оборудовани  (например, на воде).Methods are known for the hydraulic and bench tests of pumps, hydraulic machines, hydraulic fittings and other hydraulic equipment for which tests are carried out on a fluid that is working for this type of equipment (for example, on water).

Общим недостатком всех известных способов  вл етс  то, что после проведени  испытаний изделие подлежит полной разборке дл  удалени  образовавщейс  при испытани х коррозии, консервации жировым солидолом внутренних поверхностей деталей машин и последующей сборке. При этом, учитыва  сложную конфигурацию деталей, недоступные поверхности остаютс  непротертыми и несмазанными. Кроме того, недостаточно качественное удаление с поверхностей воды способствует распространению корроаии даже и под слоем смазки.A common disadvantage of all known methods is that, after testing, the product must be completely disassembled to remove the corrosion of the surfaces, the preservation of the internal surfaces of the machine parts with fatty grease and the subsequent assembly. At the same time, taking into account the complex configuration of parts, inaccessible surfaces remain non-rubbed and non-lubricated. In addition, insufficient quality removal from the surface of the water contributes to the spread of corrosion even under a layer of lubricant.

Предложенный способ испытаний гидрооборудовани  отличаетс  тем, что в качестве испытательной жидкости :используют раствор ингибитора , например водный раствор нитрата натри  и кальцинированной соды.The proposed method of testing hydraulic equipment is different in that as the test fluid: an inhibitor solution is used, for example an aqueous solution of sodium nitrate and soda ash.

Предложенный способ позвол ет повысить надежность защиты гидрооборудовани  от коррозии, сократить количество ручных трудоемких работ и врем  на операци х По переборке гидрооборудовани , повысить качество изделий, что  вл етс  полезным.The proposed method makes it possible to increase the reliability of protection of hydraulic equipment against corrosion, reduce the amount of manual labor-intensive work and time for operations. By re-assembling hydraulic equipment, improve the quality of products, which is useful.

При использовании предложенного способа отпадают все указанные выше операции по разборке, удалению образовавшейс  коррозии, консервации и последующей сборке, так как изделие после испытаний не требует специальной консервации, а следовательно, и не подлеж.ит разборке. В случае применени  ингибированной жидкости все поверхности деталей сложной конфигураци1И оказываютс  смазанными ингибитором , образующи.м нр.и высыхании пленку, прекращающую коррозионный процесс. Оставшийс  в каналах издели  ингибиторный раствор не вли ет на коррозионный рост, а наоборот, при медленном испаре№ 151850- 2 НИИ создает благопри тную среду; котора  совершевно приостанавливает коррозию, в том числе даже мелкой чугунной стружки и металлическг;н пыли, осевших на стенках издели .When using the proposed method, all the above operations for disassembly, removal of the resulting corrosion, preservation and subsequent assembly, are eliminated, since the product after testing does not require special preservation and, therefore, is not subject to disassembly. In the case of the use of inhibited fluid, all surfaces of parts of a complex configuration, And turn out to be oiled with an inhibitor, forming a liquid and drying film, stopping the corrosion process. The inhibitor solution remaining in the channels of the product does not affect corrosion growth, but on the contrary, with a slow evaporator No. 151850-2, the Scientific Research Institute creates a favorable environment; which completely stops the corrosion, including even small pig-iron chips and metal dust that are deposited on the walls of the product.
