Abstract
The utility model relates to a diesel engine oil injector test bed high-pressure pump, which belongs to the detection and maintenance equipment, and is characterized in that: the part on a plunger sleeve which is matched with a high-pressure pump casing is provided with a sealing ring, and the wall thickness of the plunger sleeve with the outer surface being integrally in three staircase cylindrical shapes is respectively 7mm to 8mm, 5mm to 6mm and 3.5mm to 4.5mm. Due to the adoption of the high-pressure pump, the sealing property between the plunger sleeve and the high-pressure pump casing can be improved, the integral strength of the plunger sleeve can be improved, and the characteristics such as simple structure, strong oil supply capacity, wide application range and good detection quality can be realized.
Description
Technical field
The utility model belongs to the detection maintenance of equipment, relates generally to a kind of diesel injector and detects the fuel pressure pump that maintenance is used.
Background technique
In order to improve the oil atomizing performance of diesel injector, reach the abundant burning of diesel oil, improve the diesel oil utilization ratio, at present, the cracking pressure of diesel injector is brought up to 24-28Mpa by 22Mpa traditionally, and wherein the highest cracking pressure has reached 31.4Mpa.High cracking pressure requires the fuel oil high-pressure service pump on the diesel injector test stand should have higher supply capability.But because the defective on the structural design, sealing is poor between used fuel oil high-pressure service pump ubiquity plunger bushing and the high-pressure service pump housing, and the problem of plunger bushing bulk strength deficiency has reduced the detection quality of diesel injector.
Summary of the invention
The purpose of the utility model is exactly the problem that exists to above-mentioned existing technology; Actual demand in conjunction with the diesel injector detection; Design provides a kind of diesel injector test stand high-pressure service pump of new structure, reaches to satisfy and adapt to various high cracking pressure diesel injectors to detect the purpose of using, improving supply capability and detect quality.
The basic design of the utility model is that diesel injector test stand high-pressure service pump comprises the high-pressure service pump housing and is fitted in plunger bushing and the plunger in the high-pressure service pump housing, on plunger bushing, is positioned at the equipped seal ring in the position that cooperatively interacts with the high-pressure service pump housing; Described outer surface integral body is the columned plunger bushing wall thickness of three ladders and is respectively δ
1=7-8 millimeter, δ
2=5-6 millimeter, δ
3=3.5-4.5 millimeter.
The utility model has improved sealability and the plunger bushing bulk strength between plunger bushing and the high-pressure service pump housing, have simple in structure, supply capability is strong, applied widely, detect the measured characteristics of matter.
