The hydraulic nut working system is mainly composed of three parts: ① ultra high pressure oil pump (manual, electric or pneumatic) (optional) ② ultra high pressure hose assembly (including quick-change joints) (optional) ③ hydraulic nut (or Hydraulic bolt tensioner) Wide application of hydraulic nuts The structural speciality and superiority of fastening of hydraulic nuts have been widely used in various fields of strong anti-loosening fastening and strong jacking and strong connection locking, especially suitable for Strong compression, strong ...
Due to the many restrictions of the place of use, when choosing a wrench, you must pay attention to the specific location of the space used by the wrench! For the problems that may be encountered at the scene, we have summarized them into the following five types in the form of pictures and texts, please refer to them.
Bayer hydraulic pump station pressure setting: a) Bayer company sets the pump station pressure according to the required torque value and the type of wrench used by querying the Bayer hydraulic wrench wrench book "pressure-torque comparison table". For example: set torque = 4620N.M, select Bayer hydraulic wrench, query the torque comparison table RTA series in BAIER series hydraulic wrench operation and maintenance manual, torque 4620N.M corresponds to the pump station set pressure is 30MPa. b) When set ...
Reasons for failure of hydraulic cylinders: In recent years, the maintenance mode of hydraulic cylinders in most enterprises has remained in the category of simple replacement, that is, only replacing seals and performing simple grinding and cleaning, even for severely damaged parts. However, after simple maintenance, the hydraulic cylinder has a short service life, a high failure rate and high maintenance costs. It can be seen that replacement is not a core measure of maintenance management. Enterprises should first analyze the failure reasons of the hydraulic system in essence to ensure the effective operation of the equipment to the greatest extent. ...
The difference between a hydraulic motor and a hydraulic pump: 1. A hydraulic pump is a conversion device that converts the mechanical energy of a motor into hydraulic energy, and outputs a flow rate and pressure, hoping for high volumetric efficiency; a hydraulic motor is a device that converts the pressure energy of a liquid into mechanical energy Output torque and speed are expected to have high mechanical efficiency. Therefore, the hydraulic pump is an energy device, and the hydraulic motor is an actuator. 2. The steering of the output shaft of the hydraulic motor must be able to rotate forward and reverse, so its structure is symmetrical; and some hydraulic pumps (such as gear pumps, vanes ...
1. Power part-converts the mechanical energy of the prime mover into pressure energy (hydraulic energy) of the oil. For example: hydraulic pump. 2. Execution part-convert the oil pressure energy input by the hydraulic pump into mechanical energy that drives the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3. Control section-used to control and adjust the pressure, flow and flow direction of the oil. For example: pressure control valve, flow control valve and directional control valve. 4. Auxiliary parts-connect the first three parts together to form a system, starting to store oil ...
