Gear oil pump is mainly used in oil, chemical, metallurgy, mining, power station and other industries, such as oil medium transfer, supercharged, fuel injection, etc., as well as thin oil circulation in large machinery and equipment. Lubrication pumps can be used in all kinds of machinery and equipment. use. Motor overheating is a common problem in the working process of gear oil pumps. The specific analysis and detection are as follows: 1. Does the scope of use (flow, head) exceed the design...
Firstly calculate the electronic gear ratio and pulse equivalent when the rated motor speed is based on the rated motor speed. 1) Position loop upper limit frequency = weekly command pulse × motor speed; 2) Week command pulse = position loop upper limit frequency / motor speed 3) Electronic gear ratio = encoder resolution / weekly command pulse = encoder resolution / (position loop upper limit frequency / motor speed) = (encoder resolution × motor speed) / position loop upper limit frequency 4)...
The reducer generally achieves the purpose of deceleration by meshing a motor, an internal combustion engine or other high-speed power through a large gear with a small number of teeth on the input shaft of the reducer to reduce the large gear on the output shaft. The reducer is used for low speed and large speed. Torque transmission equipment, this is a common-sense problem, not to mention more, the ordinary reducer will also have several pairs of identical principle gears to achieve the...
Gear reducer motor introduction: What is a gear motor? In front of the output shaft of a vertical ordinary motor (single-phase or three-phase asynchronous motor), a gear reducer is mounted to form a gear motor. What kind of gear reducer? 1. Vertical type (with direct type and single-phase three-phase type) 2. Horizontal (Direct and Biaxial) 3 planetary gear reducer 4. Cylindrical gear reducer Cylindrical involute gear reducer models are suitable for building materials, lifting, transportation,...
Classification of fan-shaped valve electro-hydraulic fan-shaped valve Brief description of fan-shaped valve | Classification of electro-hydraulic fan-shaped valve Brief description of the fan-shaped valve as a discharge valve, installed under the ash bucket, its classification is mainly in two aspects: 1. Driven Installation 2. Sector valve housing Angle. There are two options for the drive position of the fan valve. The first is to mount the drive on the housing of the fan valve. The type has...

The hydraulic valve is an automation component operated with pressure oil. It is controlled by the pressure oil of the pressure distribution valve and is usually used in combination with an electromagnetic pressure distribution valve. It can be used to remotely control the on-off of oil, gas and water piping systems in hydropower stations. Commonly used for clamping, control, lubrication and other oil. There are direct-acting and pilot-type points, and many use pilot type. The function is used...
Due to the structure of the displacement limit, it is generally considered gear pump can only be used as a constant flow hydraulic source. However, the attachment-threaded coupling valve scheme is effective in increasing its functionality, reducing system costs and increasing system reliability. As a result, gear pump performance can approach the costly and complex piston pump. For example, the direct installation of the control valve on the pump eliminates the need for piping between the pump...
