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.

wire braided hose analytical deduction of the machine works when using the valve manifold

Installation and commissioning
1 Handling: The machine should move the bar using a forklift or handling, the body is not allowed to tilt. Non- moving parts of the lift lock and scale .
2 Installation: The machine required level fixed on a solid foundation , and for ground handling .
3 oiling : open the case , parher wire rope ferrule adding 60 liters fuel tank 46 hydraulic oils .
4 Electrical connection : Connect the power cord to the machine specified power supply , observe the rotation jog motor , the motor rotation direction should be consistent with the pump requires .
5 Check Ruler : Ruler located cylinder front cover, is used to adjust the amount withheld shrink the size of the socket . Turn the adjusting the amount of shrinkage is reduced ; counterclockwise to adjust the amount of shrinkage increases. Ruler seat by spring force three screws on the pressure in the cylinder cover , hand pulling the ruler ( the direction perpendicular to the end face of the cylinder ) , the ruler should be flexible and leave the cylinder seat cover, after the release, by the spring force in the cylinder compression automatically on . Before you begin withholding , you should carefully check whether the scale stretching flexible . The ruler can not be fastened with screws on the fuel tank , otherwise it will damage the ruler.
6 pressure adjustment : machine parher hydraulic valve system pressure is 20Mpa, relying on relief valve adjustment . Clockwise adjustment pressure, counterclockwise to adjust the pressure decreases.
7 speed adjustment mold : mold the pace , controlled by the shunt valve clockwise to adjust , mold speed, counter-clockwise to adjust , slow down the speed of the mold , but the mold too fast will make noise increases .

universal testing machine selection should hydraulic hose

1, the choice of models: first determine the required test material vigorously tested the most value. parher hydraulic blocks Maximum force in 2KN below, generally used in single column electronic tensile testing machine can be; For 2KN to 50KN force value in the interval, we generally use two-column desktop electronic universal testing machine; at 50KN or more, should be used and ground electronic universal testing machine up.
2, universal testing machine test speed and height options: Depending on the product's performance to be measured, roughly determine the testing machine test speed, (best buy can set the speed test models). Experimental tests needed to understand space test requirements beam displacement and vertical test space (generally, beam displacement 898mm, vertical test space 1067mm). If the elastomer test beam displacement and vertical test space will require a little higher. Specific circumstances need to follow the experimental requirements to be.
3, the load sensor selection: According to the requirements of the experiment he has done select the appropriate 60 Cone seal hose fitting sensors, sensor selection principle is doing experiments is not less than the minimum force sensor maximum range of 10%, otherwise you will need to select a different range sensors.
Note: Generally, the sensor maximum range of 10% or less accuracy is unstable, the measured data is not accurate.
4, the choice of compliance testing machine: Any mechanical system are deformed by the force, no matter how slight deformation, the deformation is called flexibility. The test results and can lead to serious errors. Particularly in small stroke required in the high load test. Therefore, when selecting the test machine should be selected beams, load cell and fixtures relatively high stiffness testing machine to ensure that the results are correct.
5, the fixture of choice: the choice of fixtures should follow: The specimen will not slip and will not cause breakage clip, and ensure that the force of the axial symmetry principle. In some 74 jic female fitting cases, the clamping requires very special, would require special fixtures or tooling designed to meet specific test criteria.
