Description
Technical field
The utility model relates to a kind of diesel engine oil-way exhaust apparatus, particularly a kind of practice-training teaching diesel engine oil-way exhaust apparatus.
Background technology
The modal fault of diesel engine is exactly that oil circuit enters air.Carrying out, in diesel engine oil-way exhaust practice-training teaching, needing the exhaust bolt often turned on injection pump, to be discharged by the air in oil circuit.But operation can cause the exhaust bolt matching thread pair on injection pump to be damaged frequently, and once damage, very burden can be brought, the lighter causes poorly sealed and gas leak of the oil leakage, difficulty may be repaired because the screw hole on fuel injection pump housing damages time serious, even injection pump precision pair can be caused to damage because iron filings enter in injection pump.Even if repaired by strengthening threaded hole, but operate frequently and it can be made again to damage very soon, cause the damage of fuel injection pump housing the most at last, bring very large economic loss.This device is developed for head it off just.
Utility model content
The purpose of this utility model is to solve the defect being vented operation frequently and the exhaust bolt matching thread pair on injection pump can be caused to damage, and provides a kind of easy to operate, durable oil-way exhaust apparatus.
For solving the problem, the utility model adopts following technical scheme:
A kind of practice-training teaching diesel engine oil-way exhaust apparatus, it is characterized in that: the exhaust bolt seat be connected with injection pump, one end of exhaust bolt seat arranges the stud be connected with injection pump, the other end arranges screw, and between bottom the stud end face on exhaust bolt seat and screw, the air hole run through is set, exhaust bolt seat is arranged and is communicated with its screw and extraneous vent port.
In exhaust bolt seat, screw assembling cone screw, arranges the threaded post be connected with screw in exhaust bolt seat in the middle of cone screw, and its one end arranges the sealing cone be sealed and matched with one end of air hole, and the other end arranges knurling handle.
The root suit O-ring seal of stud in above-mentioned exhaust bolt seat.
The beneficial effects of the utility model are: after 1. having installed gib screw seat, dismounting exhaust bolt seat is not needed during bleeding, make the screw thread on fuel injection pump housing achieve reliable protection like this, also indirect protection injection pump, avoids because the pump housing damages the economic loss brought; 2. exhaust bolt seat and cone screw adopt copper material and taper fit, improve sealing, substantially prolongs serviceable life; 3. this device is easy for installation, simple to operate, and cone screw one end outer rim designs according to annular knurl, by instrument manual operation, can not substantially increase the convenience of practice-training teaching; 4. dependable performance, is easy to realize, promote.
Accompanying drawing explanation
Fig. 1 the utility model structural drawing;
Fig. 2 the utility model installation site schematic diagram.
Embodiment
A kind of practice-training teaching diesel engine oil-way exhaust apparatus, as shown in Figure 1, comprise the exhaust bolt seat 1 be connected with injection pump, exhaust bolt seat 1 one end arranges the stud be connected with injection pump, the other end arranges screw, and in exhaust bolt seat 1 stud end face with bottom screw between air hole 1a be set be communicated with.On the side of exhaust bolt seat 1, and bottom the screw of exhaust bolt seat 1, arrange and be communicated with this screw and extraneous vent port 1b.
Assemble cone screw 2 in the screw of exhaust bolt seat 1, arrange the threaded post coordinated with the screw in exhaust bolt seat 1 in the middle of cone screw 2, and its one end arranges the sealing cone be sealed and matched with air hole 1a one end, the other end arranges knurling handle.
The stud root cover of exhaust bolt seat 1 has O-ring seal 3.
As shown in Figure 2, installation method of the present utility model is as follows:
The first step: the former exhaust bolt (any one in 2) on diesel injection pump is pulled down, removes the greasy dirt around clean injection pump screw hole;
Second step: the stud of the exhaust bolt seat 1 in this device surface is coated with a little fluid sealant, and applies moment and be screwed in injection pump screw hole;
3rd step: with the tight cone screw 2 of hand-screw.
As shown in Figure 2, using method of the present utility model is as follows:
When carrying out oil circuit bleeding real training, below this device, place an oil tray, with hand-screw pine cone screw 2, press transfer pump, the air in oil circuit and gas-oil mixture are discharged.After draining gas, screw cone screw 2.
As shown in Figure 2, replacing options of the present utility model is as follows:
If this device damages, exhaust bolt seat 1 can be backed out, integral replacing, any impact can not be produced on fuel injection pump housing.
Claims (2)
1. a practice-training teaching diesel engine oil-way exhaust apparatus, it is characterized in that: the exhaust bolt seat (1) be connected with injection pump, one end of exhaust bolt seat (1) arranges the stud be connected with injection pump, the other end arranges screw, and between bottom the stud end face on exhaust bolt seat (1) and screw, the air hole (1a) run through is set, exhaust bolt seat (1) is arranged and is communicated with its screw and extraneous vent port (1b);
Screw assembling cone screw (2) in exhaust bolt seat (1), the threaded post be connected with screw in exhaust bolt seat (1) is set in the middle of cone screw (2), and its one end arranges the sealing cone be sealed and matched with one end of air hole (1a), and the other end arranges knurling handle.
