Work Wear: Hydraulic pump working principle and type of introduction

Hydraulic pump is a hydraulic system of power components, is driven by the engine or motor, sucked from the hydraulic tank, forming a pressure oil discharge, sent to the implementation of components of a component. Hydraulic pump according to the structure is divided into gear pump, piston pump, vane pump and screw pump. The following small series for everyone to introduce the type of hydraulic pump and hydraulic pump working principle. The working principle and type of hydraulic pump Hydraulic pump type 1, gear pump: smaller size, simple structure, less stringent requirements on the cleanliness of oil, the price is cheaper; but the pump shaft by unbalanced force, serious wear and tear, leakage Larger. 2, vane pump: divided into double-acting vane pump and single-action vane pump. This pump flow uniform, smooth operation, low noise, pressure and volumetric efficiency than the gear pump, the structure is more complex than the gear pump. 3, the plunger pump: high volumetric efficiency, small leak, can work under high pressure, mostly for high-power hydraulic system; but the structure is complex, high precision materials and processing requirements, the price is expensive, high oil cleanliness requirements. The working principle of the hydraulic pump Pump is an energy conversion device, the motor rotating mechanical energy can be converted to hydraulic output. Hydraulic pump is to rely on the principle of sealed volume changes to work, it is generally referred to as a positive displacement hydraulic pump, Figure 2-l is shown in the working principle of a single-plunger hydraulic pump plunger 2 installed A sealing volume a is formed in the cylinder body 3 and the plunger is always pressed against the eccentric 1 under the action of a spring 4. When the prime mover drives the eccentric wheel 1 to rotate, the plunger 2 reciprocates, so that the size of the sealed volume a periodically alternates. When a small from the small to form a part of the vacuum, so that the fuel tank under atmospheric pressure, through the suction tube top open check valve 6 into the oil chamber a and achieve oil absorption; the other hand, when a from large to small, a cavity Full of oil will open the check valve 5 into the system to achieve pressure. In this way, the hydraulic pump converts the mechanical energy input by the prime mover into liquid pressure energy, and the prime mover drives the eccentric wheel to continuously rotate, and the hydraulic pump constantly sucks and presses oil.

PCD Step Reamers

PCD Step Reamers has high processing efficiency, can be hinged together with several concentric holes, the hinged hole has high concentricity, high precision and long service life, which saves the tool change time of the machine tool and is easy to guarantee the product. Quality; can be used for precision reaming of non-ferrous metals such as aluminum alloy, titanium alloy and copper alloy;
Product Scope: Mobile 3C IT Industry Telecom 3G industry, automotive, aerospace and other aluminum products processing Hardware industry, cutting speed can reach more than 500M, the hinged hole can achieve mirror effect, greatly improve the quality of the product!

PCD Step Reamer is a multi-diameter tool allowing for excellent hole size and concentricity between diameters. Nowadays, more and more automotive gearboxes are made of die-cast aluminum alloys with complex shapes. There are many stepped shaped holes on the gearboxes, in order to meet high efficiency and high precision processing, it is especially suit for machining with PCD step reamers.

Choosing PCD step reamer is very often the best way to reduce the total cost, using highly advanced PCD Reamer can reduce the number of tools needed and increasing productivity, thus lowering your production unit costs considerably.

Advantages:

Unique guidepad geometry allows for excellent roundness and straightness, even in an interrupted cut condition.

Surface roughness is reduced obviously.
