Features of Manual Pumps

Manual pumps are the power source of thread fastener and fastening device. Accurate control of bolt pre-tightening force can be achieved, and the working pressure of hydraulic oil can reach 300 Mpa. At present, coal, electric power, chemical industry and other industries are using high-strength hydraulic nuts or hydraulic stretchers. Ultra-high pressure manual night wish [...]

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 [...]

Maintenance of Hydraulic Cylinders

Maintenance of Hydraulic Cylinders When the hydraulic jack is used, the bottom should be flat and tough. Oil-free wood panels to expand the pressure surface for safety. It is not possible to replace the board with iron plates to prevent slipping. It is required to be stable when lifting, and it is necessary to check [...]

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 [...]

Using Method of Hydraulic Jacks

Before use, it is necessary to check whether the parts are normal. Check whether the piston, joint, high-pressure hose, etc. are leaking oil. When using, the provisions of the main parameters should be strictly observed. Avoid excessive overload. Otherwise, when the lifting height or lifting tonnage exceeds the specified level, serious oil leakage will occur [...]

Hydraulic Tools

Hydraulic tools are the organic combination of hydraulic system and common tools as a whole. The powerful hydraulic power will be converted into reciprocating linear motion, rotary motion, cycloid motion and other mechanical movements. A complete hydraulic tool system consists of five parts, namely, power element, actuator element, control element, auxiliary element and hydraulic oil. [...]

Working Principle of Hydraulic Jack

The working principle of hydraulic jack is that the wrench moves upward to drive the small piston upward. The oil in the tank is sucked into the lower part of the small piston through the tubing and one-way valve. When the wrench presses down, the small piston is driven downward. The oil in the lower [...]

Advantages of Pneumatic Wrench

Pneumatic wrench, also known as ratchet hand and electric tool assembly, is mainly a tool to provide high torque output with minimum consumption. It accelerates the rotation of an object with a certain mass through a continuous power source, and then collides with the output axis instantaneously, so that a relatively large output of torque [...]
