What Is The Reason For The Weakness Of The Hydraulic Oil Pump Of The Mucking Machine,mucking Loader?
The hydraulic oil pump is the power transmission device of the mucking loader, and it is the power source of the mucking machine. In the application of machinery and equipment, it is inevitable to encounter some common failure problems, including fatigue in the work of the machinery and equipment. What is the reason for this?The problem of wear of the distribution plate of the tunnel mucking loader is known from the principle of this cycloid hydraulic oil pump. The planetary reducer gear distribution plate and the cycloid motor rotor are connected by a small linkage shaft to rotate together, and at the same time the distribution plate is on the valve plate. The factors that cause the excessive wear of the friction pair due to rolling rotation are as follows: When a new hydraulic oil pump is just installed, because the gear oil is not filled in the casing of the cycloid hydraulic oil pump, the friction surface of the friction pair is not sufficiently lubricated.In particular, the mucking machine has a relatively large load in the early stage of operation, which aggravates the wear of the distribution plate and the valve plate, and the friction surface roughness decreases, which increases the storage space of the friction residue, and the fine particles entering the surface and the alloy particles that are cut out. It rotates with the valve plate, which increases the wear and tear. The filter element of the hydraulic transmission system is ineffective, so that fine particle residues penetrate into the oil, and the small fine particles enter the friction surface during the whole process of the valve plate rotation, which causes the wear-resistant material to wear on the friction surface. Due to the wear between the valve plate and the valve plate, the gear oil is entering, and the pump oil channel is connected by a gap.
