What are the characteristics of the HYDRAULIC GEAR PUMP

HYDRAULIC GEAR PUMP has a simple structure, easy processing, small size, lightweight, and has the characteristics of strong self-priming ability, insensitive to oil pollution, etc., and thus is more widely used. China's HYDRAULIC GEAR PUMP industry has two major competitive advantages: on the one hand, it has the competitive advantage of low cost; on the other hand, the domestic construction, petroleum, petrochemical, environmental protection market's rapid growth, and major water transfer projects also provide important support for the development of China's HYDRAULIC GEAR PUMP industry. China's sustained growth in market space is a prerequisite for the domestic HYDRAULIC GEAR PUMP industry to maintain its advantages.

Good self-priming performance

The self-priming capability of HYDRAULIC GEAR PUMP refers to the ability of HYDRAULIC GEAR PUMP to suck oil from the open tank below the lower end of HYDRAULIC GEAR PUMP at the rated speed. The size of the suction capacity is often expressed in terms of the suction height (or vacuum). the essence of the self-suction capacity of HYDRAULIC GEAR PUMP is that the hydraulic oil in the tank flows into the suction chamber under the action of atmospheric pressure because of the formation of a local vacuum in the suction chamber of HYDRAULIC GEAR PUMP. So the greater the vacuum in the suction chamber of the hydraulic HYDRAULIC GEAR PUMP, the higher the suction height. However, the value of the vacuum degree is limited by the cavitation condition. No matter the suction height, the flow rate of the suction port, or the hydraulic loss of the suction pipe. If they increase, it will affect the pressure drop of the hydraulic HYDRAULIC GEAR PUMP. When the drop to lower than the air separation pressure of the fluid at the prevailing temperature, it will produce cavitation and cavitation, which will cause a significant increase in vibration and noise, a significant reduction in flow and efficiency, and may even destroy the parts of the hydraulic HYDRAULIC GEAR PUMP. Therefore, the suction height of a hydraulic HYDRAULIC GEAR PUMP cannot be too high, and the general suction height allowed by a HYDRAULIC GEAR PUMP does not exceed 500mm.

Simple structure and easy processing

The most basic form of HYDRAULIC GEAR PUMP is two gears of the same size meshing and rotating inside a closely matched housing, which is similar to an "8" shape inside the housing, with the outer diameter and sides of the gears closely matched with the housing. The material from the extruder enters the middle of the two gears at the suction port and fills this space, moving along the shell with the rotation of the teeth, and finally discharging when the two teeth mesh. And the herringbone gear is smaller than the helical gear unevenness, the fewer the number of teeth the greater the pulsation rate. The theoretical flow rate is determined by the size and speed of the working parts, and is not related to the discharge pressure; the discharge pressure is related to the pressure of the load.
