In many self-priming or impeller type oil pump signs are marked with a cavitation words, the user can not help but ask what is cavitation phenomenon? The following: the performance of the pump because of its pumping special liquid type, na

(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

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

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

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

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

The axial force of the stainless steel gear pump will make the gear move along the axial direction to the suction chamber, increasing the wear of the gear meshing part, so try to balance the axial force. The methods are as follows: (1) Ins

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

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

A centrifugal pump is made up of many parts. According to the working state of each part, it can be roughly divided into three types: rotating parts, fixed parts and handover parts. Take the single stage single suction horizontal centrifug
