Device for realizing opposed two-stroke cylinder sleeve flow test

Abstract

The invention relates to a device for realizing an opposed two-stroke cylinder sleeve flow test. The device comprises a cylinder sleeve (1), a supporting plate (2) with a threaded hole, a rubber ring (3) with the diameter of 3mm, a bolt (4), a lock washer (5), a handle (6), a single-head stud (7), a piston plunger (8), a double-head stud (9), a bolt (10), a gasket (11), a pressing plate (12) with a threaded hole, a supporting block (13), and a test bench surface (14). The cylinder sleeve (1) is internally provided with the piston plunger (8) with matched inner diameter. The threaded hole of the supporting plate (2) is matched with the stud part of the single-head stud (7) and is in contact with and connected with the cylinder sleeve (1). A device used for fixing the cylinder sleeve (1) is respectively arranged at the symmetrical positions of two sides of the cylinder sleeve (1). The device has the advantages of simple structure, convenient use and quick installation, the test precision and tightness can be ensured, and flow tests in different flow cross section of a channel can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of diesel engine cylinder head air passage performance testing, and in particular relates to a device for realizing air flow testing of opposed two-stroke cylinder liners. Background technique [0002] The steady flow test bench for measuring the air passage performance of the diesel engine cylinder head is designed according to the traditional cylinder head structure. When measuring, install the cylinder head under test with valves, valve springs and other accessories on the test bench for positioning and pressing, input the parameters of the cylinder head under test and the lift of the airway, turn on the equipment, and automatically measure different lifts under different lifts. A performance indicator of the airflow into the airway. The opposed two-stroke cylinder liner is completely different from the traditional cylinder head, and the existing gas steady flow measurement test bench cannot achieve the ...
