Fault Analysis of Hydraulic Stretcher
Fault analysis of hydraulic stretcher 1. Oil leakage of hydraulic tensioner Main causes: wear or aging of the upper and lower sealing rings; The bleed screw is not tightened or damaged; During operation, the lift of the hydraulic stretcher exceeds the maximum lifting height. Measures: replace the sealing ring; Tighten or replace the bleed screw; [...]
Hydraulic Oil Determines the Performance of Hydraulic Jack
Hydraulic oil determines the performance of hydraulic jack Hydraulic oil plays a very important role in hydraulic jack. Good hydraulic oil can greatly improve the performance of hydraulic jack and prolong the service life of hydraulic jack. So, what good characteristics should a good hydraulic oil have? 1. Good demulsibility and hydrolysis stability. During the [...]
Hydraulic Jack Self Locking Device
What is the performance and special use of hydraulic jack self locking device? Under what working condition is hydraulic jack self-locking device used? The self-locking jack is used for the place where the heavy object needs to be maintained for a long time. It can still support the heavy object on the ground after the [...]
How to Control the Excessive Oil Temperature of Hydraulic Pump
The Oil Temperature of Hydraulic Pump in the hydraulic system is controlled within a certain range. If it exceeds this standard range, it will bring many bad effects to the hydraulic system. The reason for the increase of oil temperature is as follows: When the viscosity of oil is reduced, the solvent efficiency of the [...]
Classification of Hydraulic Jacks
Classification of Hydraulic Jacks Hydraulic jacks are divided into: general hydraulic jacks and special hydraulic jacks. The universal hydraulic jack is suitable for all kinds of lifting operations with low lifting height. It consists of oil chamber, oil pump, oil storage chamber, piston, rocker, oil valve and other major parts. When working, as long as [...]
Precautions for Hydraulic Jack
Precautions for Hydraulic Jack If there is a gap in the use, you can loosen the oil drain screw on the pump body, and then open the pump body vertically down a few times, then tighten the oil drain screw to continue using. When using hydraulic jacks, no eccentric load or overload shall be added [...]
Engineering Hydraulic Jack
In engineering operation, engineering hydraulic jack is a kind of lifting equipment, unlike electric hoist, which lifts all kinds of materials by tension, while electric hoist lifts all kinds of materials. Take hydraulic jack as an example, before using, we must check whether the reserved hole is unblocked, whether the steel strand is rusted or [...]
Advantages of Hydraulic Torque Wrench
Conventional hydraulic torque wrench gloves are generally composed of hydraulic torque wrench body, special pump station for hydraulic torque wrench, double high pressure hose and high strength heavy sleeve. Hydraulic torque wrench has two series: driving hydraulic wrench and hollow hydraulic wrench. The advantages are as follows: Drive hydraulic torque wrench: Using high-tech aerospace materials [...]
Hydraulic Oil Viscosity of Hydraulic Wrench Pump
Hydraulic oil viscosity of hydraulic wrench pump is an important index of hydraulic oil. Small viscosity will increase leakage and reduce volumetric efficiency. Viscosity will cause loss of viscosity and cause cavitation or seizure. Generally, the kinematic viscosity of hydraulic oil used in hydraulic system is 106m/s. The detailed indexes required for viscosity of hydraulic [...]
Features of Hydraulic Torque Wrenches
There are two series of hydraulic torque wrenches: driving hydraulic torque wrench and hollow hydraulic wrench. The driving hydraulic torque wrench is used in conjunction with the standard sleeve. It is a universal hydraulic wrench with a wide range of applications. The hollow hydraulic wrench is thinner in thickness, especially suitable for narrow space. It [...]
