The air jack manufacturers in china have high requirements for the performance of jack products.
The air jack overcomes the inclination of a single jack when lifting heavy objects, resulting in damage and danger to the lifting objects. Multi-top synchronization diverter valve should be used when in use, and the load lifted by each top should be balanced to keep the lifting and lowering speeds synchronized. It should also be considered that the ground may sink due to the uneven weight of the lifting object, causing the lifting object to tilt and causing man-made damage.
Jack is equipped with pressure holding and overflow devices to prevent overload, and is equipped with a safety valve to protect the synchronous jacks to achieve safe operation and protect the lifting objects. The pressure holding device is more suitable for falling beams in construction with high pressure holding requirements.
There are several types of mechanical jacks and air jacks, with different principles. In principle, the basic principle based on hydraulic transmission is the Pascal principle, that is, the pressure of the liquid is the same everywhere.
In this way, in a balanced system, the pressure exerted on the smaller piston is smaller, and the pressure exerted on the larger piston is also larger, which can keep the liquid still. Therefore, through the transfer of liquid, different pressures on different ends can be obtained, so that a transformation can be achieved. The hydraulic jack that we commonly see uses this principle to achieve force transmission.
Air jack, its internal thread has self-locking characteristics, no matter how much force is applied in the axial direction, the jack will not move in the axial direction. Only by reciprocating the handle (Hand Shank), pulling the pawl pushes the ratchet to rotate in the gap, the small bevel gear drives the big bevel gear and the lifting screw rotates, so that the lifting sleeve can be raised or lowered to achieve the lifting Heavy pull function. But it is not as simple as a hydraulic jack.
Jacks application scope and performance details analysis (analysis; in-depth analysis) Although jacks are relatively common, it is not so easy to understand all their application fields. In order to let everyone better apply this jack, below Mainly explain its main application range and related performance.The air jack manufacturers in china of jacks have high quality and good performance .
Jacks are currently extensively used in various pipeline construction, construction, road and railway construction, power station construction, equipment upgrades, and mechanical disassembly. They have a tensioning function. The center hole can be used for cables, steel bars (English: steel bar), etc. Through, the center hole can be processed according to user needs, and oil cylinders of different specifications and different strokes can be made according to user requirements, and hydraulic pump stations and manual oil pumps can be optional.
This type of equipment has small volume, light weight, compact structure, simple operation, ultra-high pressure, small flow, and can be equipped with low-pressure pumps to increase the rate. On the basis of the road, various hydraulic components can be added. Such as electromagnetic valve (electromagnetic valve), pressure relay, remote control switch, hydraulic lock, etc. It can be used under any pressure within the rated pressure.
