Abstract
The invention relates to an on-board hydrostatic test water inlet joint tool for a cylinder sleeve and cylinder head assembly of an internal-combustion engine of a locomotive. A method comprises the following steps of: outwards forming an inlet in the side wall of a water jacket in closed space formed by the cylinder sleeve of the internal-combustion engine and the water jacket, and leading cooling water into the inlet during working; unfastening seals at the different positions of the closed space formed by the cylinder sleeve of the internal-combustion engine and the water jacket, mounting a water inlet joint for a test on the inlet, and connecting a high-pressure-resistant rubber tube to the water inlet joint; filling water into the closed space formed by the cylinder sleeve of the internal-combustion engine and the water jacket from the high-pressure-resistant rubber tube; closing a water outlet after the closed space formed by the cylinder sleeve of the internal-combustion engine and the water jacket is filled with the water, refastening the seals at the different positions of the closed space formed by the cylinder sleeve of the internal-combustion engine and the water jacket, and pressurizing by using a manual pressure pump; and judging whether the closed space formed by the cylinder sleeve of the internal-combustion engine and the water jacket leaks or not. A phenomenon that a large number of components are detached is avoided, most of fault treatment time is saved, the consumption of materials and equipment is reduced, the cost is also reduced, and the operation efficiency of the locomotive is improved.

B, unclamp internal combustion engine cylinder jacket and water jacket composition enclosure space sealing everywhere, access port is installed into water swivel, and connects high pressure resistant rubber tube at the rubber tube interface of water supply connector;
C, from high pressure resistant rubber tube internal combustion engine cylinder sleeve and water jacket composition enclosure space in pour water;
D, after water fills in the enclosure space of internal combustion engine cylinder jacket and water jacket composition, close water delivering orifice, by again fastening for the enclosure space sealing everywhere of internal combustion engine cylinder jacket and water jacket composition;
E, to pressurize with portable force (forcing) pump;
Whether the enclosure space of F, observation internal combustion engine cylinder jacket and water jacket composition has Seepage.
The sealing of described step (B) refers to the flange gasket sealing connected with bolted.
Described water supply connector comprises joint, pipe shaft, pipe tail and rubber tube interface, the access port of described joint and cylinder sleeve sidewall matches, the described joint other end connects pipe shaft, obtuse angle angle is become between described pipe shaft and the axis of joint, the pipe tail of the described pipe shaft other end is sealed, the sidewall that described pipe shaft is positioned at pipe tail place has rubber tube interface, and described rubber tube interface and high pressure resistant rubber tube match.
Described water supply connector is made up of copper product.
Described joint, pipe shaft, pipe tail and rubber tube interface link together with welding manner.
Beneficial effect
The invention has the advantages that, solve that frock is fixed, adjustable length, to connect with water pressure engine and the problem such as good seal; Do not need to dismantle in a large number parts, process diesel locomotive water consumption major break down efficiency can be improved, significantly reduce fault handling time; Save goods, materials and equipments, reduce spare part and the consumption of auxiliary village, reduce costs; Improve locomotive efficiency.
