随着近年来国家对装备制造业的大力扶持，各地建立装备制造业基地的积极性都很高。辽宁省葫芦岛市从2009年开始筹划将 油泵 产业作为该市的一个重点发展产业，最近他们进一步以首届中国葫芦岛打渔山泵阀产品博览会为平台广揽国内外企业。10月14日，辽宁省葫芦

从 齿轮油泵 的工作原理和特点，可以看出齿轮油泵有以下优点: (1)压力和排量的范围宽广，压力范围为0.3-4兆帕，排量可高达500米3/时， (2)输送液体的种类广，可泵送蜜糖、含颗粒性液体、汽油及合成液体等各种粘度的液体; (3)从动齿轮不受负载作用，和主动齿

FIG. 39 shows the characteristic curve of a typical gear oil pump. It can be seen from the figure that the pump power increases with the increase of pressure. It can also be seen from the figure that even under high pressure, the pump stil

In order to explain the working principle of the diesel pump, a bolt can be used as a metaphor. When the bolt turns and the nut turns, the nut will produce axial movement. Screw pump and bolt to pay back when similar at work, as the thread

The main task of gear oil pump maintenance is to check whether the working face of gear, meshing gap, pump body, end cover, side plate, pump shaft and bearing and shaft seal have scratches and cracks. Scratches or cracks should be repaired

As a turbine management personnel, in order to use and manage all kinds of pumps well, we should understand the structure, working principle and characteristics of all kinds of pumps, according to the requirements of the work, select the r

Internal meshing pump referred to as internal gear pump , its structure is more compact than the external gear oil pump, the shape size is smaller, the pressure and displacement of the general internal gear oil pump is smaller, often used

Gear oil pump according to the structure of the pump shell is divided into two pieces and three pieces. Two chip due to the processing and the axis of the more difficult, so use few, according to the structure of the gear, a set of teeth a

(I) Preparation before startup 1) Check whether the lubricating oil level of the heat conduction oil pump is in the middle line of the calibrated oil standard to avoid being too high or too low; 2) Check whether the fixed connecting screw

It has long been known that liquids such as water and oil obey Newtons law of viscosity, which states that shear stress is proportional to sliding speed. In the past, oil pumps were used to transport these fluids, but with the rapid develo
