Abstract
The utility model discloses a water pressure testing device of a diesel engine cylinder cover, which relates to an inspecting device of a diesel locomotive, in particular to a pressure testing device used in the water cylinder of the 240/275 series D type diesel engine cylinder cover. The utility model is characterized in that the water pressure testing device of the diesel engine cylinder cover structurally comprises a worktable, an 8V240ZJ diesel engine cylinder water jacket pressure testing seat fixed on the worktable, a blockage, a sealing ring and fastening bolts distributed at one end of the outer side of the pressure testing seat and vertically passing through the table top of the worktable, wherein the blockage and the sealing ring are tightly matched with an 8V240ZJ diesel engine cylinder jacket hole arranged on the pressure testing seat. The water pressure testing device of the diesel engine cylinder cover has the advantages that the abandoned cylinder water jacket can be utilized, the original cylinder head conduit is changed into the blockage for making a diesel engine cylinder cover water pressure testing board, and the testing board is matched with a pressure testing pump for finishing the test to the water pressure of the cylinder cover, thereby the operation is convenient, the functions are practical, the investment is less, and the device is especially suitable to the use in enterprises in which a few locomotives are equipped.
Description
Technical field
A kind of cylinder cover for diesel engine water test unit relates to a kind of diesel locomotive upkeep operation device, particularly the pressure testing device of 240/275 serial D diesel engine cylinder head water cavity.
Background technology
Diesel engine of diesel locomotive cylinder head and cylinder jacket and piston are formed the firing chamber, diesel oil provides power for locomotive herein after overcompression, outburst, burning, the temperature at this place can reach 2000 ℃, in order to guarantee the operate as normal of cylinder head, its indoor design has recirculated cooling water chamber and path, and the sealing property of water cavity is one of important technology index that can diesel engine operate as normal.
Each big locomotive depot of the Ministry of Railways or locomotive factory often purchase the cylinder cover for diesel engine water pressure testing board that specialized factory produces, this testing table automaticity is higher relatively, generally can finish 2-4/time experiment work, acquisition price is generally ten thousand yuan of 5-7, it is lower to provide the diesel locomotive cost performance for oneself for the few enterprise of locomotive stock, often cause the idleness of equipment, the wasting of resources.Because it is less or simply oneself do not repair in not doing that these enterprises oneself carry out the number of times repaiied in the diesel locomotive, have only the cylinder head of processing to face when repairing and just use.By the technical regulation requirement: the cylinder head water cavity must carry out the hydraulic testing, otherwise, the cylinder head burning chamber of diesel engine that in a single day leaks, the phenomenon of the failure of white cigarette appears emitting in the lighter's diesel engine, and weight person can cause diesel engine " water hammer " accident.Therefore, cylinder head being carried out the hydraulic testing is very important.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, and a kind of easy, practical, small investment again is provided, and is particularly suitable for the cylinder cover for diesel engine water test unit that some enterprises that are equipped with a small amount of locomotive use.
The purpose of this utility model is achieved through the following technical solutions.
A kind of cylinder cover for diesel engine water test unit is characterized in that its structure comprises:
The level table of worktable-this worktable for being welded into support and steel plate;
Pressure testing seat-this pressure testing seat is a 8V240ZJ cylinder jacket of diesel engine water jacket, is fixed on the table top;
8V240ZJ cylinder of diesel engine trepanning on obstruction-this obstruction and the pressure testing seat closely cooperates, the inlet opening on the sealing cylinder cap;
O-ring seal-sealing circle is that rubber seal is sleeved in the obstruction, guarantees the sealing of cylinder head and pressure testing seat;
Set bolt-this bolt has four, the uniform pressure testing seat outside that is positioned at, and an end vertically passes table surface, and the termination is connected with nut.
A kind of cylinder cover for diesel engine water test unit of the present utility model, can utilize discarded cylinder jacket water jacket, change original cylinder head aqueduct into obstruction and be made into the cylinder head water pressure testing board, being equipped with a bench teat press pump finishes cylinder head hydraulic testing work, so both easy, practical again, investment seldom is well suited for some enterprises that are equipped with a small amount of locomotive and uses.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
A kind of cylinder cover for diesel engine water test unit, its structure comprises:
The level table of worktable 1-this worktable for being welded into support and steel plate;
Pressure testing seat 2-this pressure testing seat is a 8V240ZJ cylinder jacket of diesel engine water jacket, is fixed on the table top;
The 8V240ZJ cylinder of diesel engine trepanning that stops up on 3-this obstruction and the pressure testing seat closely cooperates, the inlet opening on the sealing cylinder cap;
O-ring seal 4-sealing circle is that rubber seal is sleeved in the obstruction, guarantees the sealing of cylinder head and pressure testing seat;
Set bolt 5-this bolt has four, the uniform pressure testing seat outside that is positioned at, and an end vertically passes table surface, and the termination is connected with nut.
During practical operation, worktable adopts the level table that is welded into support and steel plate; The pressure testing seat adopts 240ZJ cylinder jacket of diesel engine water jacket, is fixed on the platform, and top is connected with cylinder head with O-ring seal by obstruction, and the hole on obstruction and the pressure testing seat closely cooperates, the inlet opening on the sealing cylinder cap; O-ring seal adopts the locomotive spare part,
Rubber seal be sleeved in the obstruction, guarantee the sealing of cylinder head and pressure testing seat; To treat that with set bolt the cylinder head of pressure testing and pressure testing seat carry out fastening; The cylinder cap water delivering orifice is connected with the motor test pump of 4DY-74/6.3 type, water is cooked medium and is checked cylinder head water cavity sealing property, at the trial motor test pump is connected with cylinder head rising pipe triangle flange with connecting tube, simultaneously that testing table and cylinder head is fastening, and require moment to be not less than 300NM, occur leaking to guarantee when suppressing 0.5MPa, to be unlikely.In suppressing process, note observing the manometric indicated value of motor test pump, when pressure is elevated to 0.5MPa, stop to suppress.At this moment with check utensil to cylinder head cross water jacket, fuel injector sheath and respectively all water cavity places check, and keep 5min not have leakage.
