american hydraulic adapter Brammer UK principle applied Pascal

the hydraulic machine Brief History 1795, J. Brammer UK principle applied Pascal invented the hydraulic machine for packaging, virgin vegetable oil. To the mid-19th century, the British began american hydraulic adapter to hydraulic press for forging, hydraulic press then gradually replaced the large steam hammer. To the 19th century, the United States made 126,000 kN free forging hydraulic press. Since then, the world has manufactured thousands of cattle more than 20 Taiwan 10 levels free forging hydraulic press, which made in China have two sets (see pictures). With the emergence of electric high-pressure pump and improvement of forging hydraulic machine is also to a smaller tonnage of direction. After the 1950s, there have been small, fast forging hydraulic press, can be equivalent to 30 to 50 kN hammer work. 1940s, hydraulic adapters  the German giant made of 180,000 kN forging hydraulic press, then the world has made more than 180,000 kN forging hydraulic machine 18 units, of which one is made in China 300 000 kN.

npt threads adapter wire rope ferrule the more highly integrated

MCM multi-chip module
To address the low single-chip integration and functional problems is not perfect, the more highly integrated, high performance, high reliability chip, high-density multilayer wire rope ferrule interconnect substrate using SMD technology composed of a variety of electronic module system, which appears MCM (Multi Chip Model) multi-chip module system.
MCM has the following characteristics:
1 package delay time narrow, easy to implement module speed.
(2) reduce machine / module package size and weight.
3 greatly improves system reliability.

parher hydraulic hose assembly omnipresent hose crimping machine

omnipresent hose crimping machine Hose crimping machine is all metal connector supporting force exerted by hose crimping machine shut mold firmly withhold its support on the rubber hose. Hydraulic rubber hose assembly has been a lot of other industries have widely adopted almost everywhere. Use face increasingly wide hose crimping machines , demand is also increasing . So now not only requires hose crimping machine with high precision, high  parher hydraulic hose assembly  , and can withhold a variety of forms , wire diameter and various layers of the elbow, flange, high pressure, large diameter hose assembly. So the hose crimping machine made ​​more stringent requirements. Hose crimping machine is a tube assemblies for hydraulic crimping device , it will by supporting the contractile force exerted by the metal connector hose crimping machine mold , the metal connector  parher reusable hydraulic fittings  withheld in the supporting construction machinery with high-pressure tubing or car on the brake pipe , oil pipe , air conditioning tubes, power tubes . Hose crimping machine is suitable for all types of machinery high and low pressure tubing, pipe , plumbing , cable connectors, automotive air conditioning pipes, power steering pipe , oil pipe , gasoline for tubing, and construction accessories , household hot water pipe withhold , widely used in vehicles, engineering machinery , hydraulic machinery , welding equipment and other industries. Category hose crimping machine , such as by using the function can be divided into high-pressure hydraulic hose crimping machine pipe , brake pipe hose crimping machine , air-conditioning duct hose crimping machine, power tube hose crimping machine, such as by mechanical structure can be divided into straight -type hose crimping machines, double column hose crimping machine, open type hose crimping machine, C- type hose crimping machine, such as by control can be divided into electromechanical hose crimping machine , PLC -type hose crimping machine, CNC -type hose crimping machine Hose crimping machine Technical guidance : 1 , the operating principle of dual hydraulic circuit , i.e., mouth and contraction of the piston forward and backward movement of the mold and the motive power of the hydraulic power source is generated . Not only does it move smoothly , return quickly , like a spring return , not open and lock the mold  parher reusable hose fittings  does not occur. And all around the cylinder locking system design through easy to withhold various shaped elbow. 2 , the hydraulic system by the motor , pump , solenoid valve , relief valve and the hydraulic valve would move back and forth with a double hydraulic circuit , but also in a double hydraulic circuit of a rapid increase in drain oil from the valve passage , in order to achieve more Quick return purposes, and the speed is adjustable , noise and system pressure is reduced. 3 , the electrical control system, the control circuit applies PLC circuit , it is easy to repair circuits , easy maintenance and replacement simple. 4 , mold and die holder withhold cumulative error -free machining process to ensure that the withholding of withholding product evenly spaced lines , no size head phenomenon . 5 , hose crimping machine for permanent mechanical precision and life on the locking mechanism assembly , not only chose the high-quality steel materials, and the use of a unique heat treatment process. So hose crimping machine long life : the selection, heat treatment, machining process and the reasonableness of the structure are inextricably linked.
