We want to measure the head of a gear oil pump. The liquid is 20℃ oil.. When the measured flow is 590m/h... Pump inlet vacuum gauge reading is -0.03MPa.. The outlet pressure gauge reads 0.48 MPa (gauge pressure).. It is known that the ver

1. The single-acting gear is embedded in the groove.. Free to slide... When rotation is generated.. The gear is thrown to the pump housing under the centrifugal action.. Gear pump is positive displacement pump.. The two adjacent gears move

First, introduce the shaft seal device The function is to prevent the liquid in the gear oil pump from leaking along the shaft or the outside air from leaking into the pump body. The commonly used shaft seal device has two kinds of packing

The working principle of KCB gear pump Structure and working principle of gear oil pump Main components: pump body, gear... Gear rod and suction valve, discharge valve. How it works: When the gear moves from left to right... Negative pressu

The structure of the gear shaft Gear shaft is located in the lower part of the gear oil pump on pump body, made up of two tapered roller bearing, its front end connected to the device in advance, after the end connected to the governor, for

Here are some technical requirements for cold processing and heat treatment of oil pumps: Main technical requirements for cold working 1. Because the shaft depends on the friction force of the two cones to transfer the torque, in order to e

The size of the market China currently has a total of 95,000 onshore production Wells, which are owned by CNPC and Sinopec. Among them, Sinopec has 21,600 and PetroChina has 73,400, which are mainly distributed in 21 onshore oil and gas fie

Research and analysis of the marketing theory of KCB gear oil pump, and the correct use of these theories is a key link for an enterprise to formulate development strategy, the main engine plant in the development of less detours, must be g

A senior Australian government official said Australia will continue to curb gear pump exports. This contradicts earlier media reports that the country may ease the ban to boost the economy. Australia banned the export of unprocessed metal

Working principle of gear oil pump 1. Driving gear; 2 a driven gear; 3 pump body; 4 meshing line The root cause of drainage work. (2) the suction and drainage cavity of the hydraulic pump must be separated. This is the fundamental guarantee

Be limited to; Large flow pulsation leads to large pressure pulsation and high noise in the system. Internal meshing gear oil pump has the advantages of compact structure, small size and light weight. Because the gear rotates in the same di

The instantaneous flow of ordinary KCB gear oil pump is described by the movement law of meshing points, while the flow characteristics of compound gear oil pump are described by the movement law of meshing points and their mutual relations

Radial fluid pressure analysis of compound gear oil pump system This chapter takes standard gear as an example to analyze the radial fluid pressure of each gear in a compound gear pump. In the normal working process of the gear oil pump, th

Optimal design is a new technology developed on the basis of the extensive application of modern computers. It is based on the optimization principle and method of comprehensive aspects of the factors, with man-machine cooperation or automa

The type of unloading groove can be divided into three kinds: 1. Double unloading groove is symmetrically arranged relative to the center line of YCB gear oil pump gear 1. Symmetrically arranged double rectangular unloading groove; 2. Symme
