Problems solved by technology

[0004] The purpose of the present invention is to provide a hydraulically balanced screw pump assembly, which solves the non-abrasion and durability of the existing screw pump assembly due to the excessive axial force and radial centrifugal force of the driven screw after the screw pump is boosted. , high vibration, high noise, high power, high energy consumption, and short service life

Embodiment Construction

[0016] Examples such as figure 1 , figure 2 The hydraulically balanced screw pump assembly shown includes a driving screw 1 and a driven screw 2 that is engaged with the driving screw 2. The driven screw 2 is axially provided with a liquid hole 10 that runs through the entire rod, that is, it runs through the entire rod. Root follower screw 2. The diameter of the liquid hole 10 is 0.3-6mm. The liquid hole 10 is used to introduce the high pressure in the high pressure area to counteract the axial force of the driven screw 2 during operation through hydraulic balance.

[0017] The driving screw 1 includes a driving end 5 and a driving helical segment 6 extending axially downward from the lower end surface of the driving end 5, and the driving helical segment 6 is provided with a driving helical groove 3; the driven screw 1 includes a driven end 7 and a The driven helical section 8 extending axially upward on the upper end surface of the driven terminal 7 is provided with a d...

Abstract

The invention discloses a hydraulic-balance screw pump assembly. The hydraulic-balance screw pump assembly comprises a drive screw and a driven screw which is engaged with and adaptive to the drive screw; and a liquid flowing hole which penetrates through the whole rod is axially formed in the driven screw. The hydraulic-balance screw pump assembly can effectively solve the problems that a current screw pump assembly is not wear-resisting and durable, is relatively high in power, is great in energy consumption and is short in service life due to the fact that axial force and radial centrifugal force of the driven screw are too great after a screw pump works and boots.

Description

technical field [0001] The present invention relates to a hydraulically balanced screw pump assembly. Background technique [0002] Screw pumps are used as fuel injection, fuel supply and delivery pumps in heating equipment. It is used as a loading, conveying and liquid supply pump in the chemical petrochemical and food industries. It is used on ships as delivery, pressurization, fuel injection and lubricating oil pumps and marine hydraulic pumps. Screw pumps are widely used in petroleum, chemical fiber, metallurgy, machinery, electric power, machine tools, ships, glass, roads and other industries. Screw pumps are suitable for conveying lubricating liquids such as fuel oil, lubricating oil, hydraulic oil, crude oil, asphalt and other similar oils. The screw pump is used as a lubrication pump in the industrial field, as a hydraulic pump in the hydraulic system, as a delivery and booster pump in the fuel system, and as a delivery and refueling pump in the oil delivery syste...
