Hydraulic Hose Fittings Three valves used correctly

Three valve is composed of three consisting of three valves communicate with each other. Each valve in the

system according to the role can be divided into: the left side of the high pressure valve, parher reusable hydraulic hose fittings the right for

the low-pressure valve, balance valve middle. The difference between the three valve Transmitter, a positive

effect, negative pressure measuring chamber and the lead point on or off; positive or negative pressure

measuring chamber is disconnected or turned on.
The main role: It is in the installation and removal of the need to use balancing valve Otherwise,

differential pressure range is generally small, if the manufacturers of overload is not strong, it is easy

to damage.
Here is a simple example: If the differential pressure is 60KPa, pipeline pressure 1MPa time, if there is no

balance valve, parher metric hydraulic hose fittings both first take positive or negative pressure chamber room, both sides would immediately lead

to a differential pressure far parher hydraulic couplers exceeds the set value because the first take that party will have a direct

and open to the atmosphere, the equivalent of 0.1MPa, this operation is fatal.

Hydraulic Hose Fittings engineering machinery electro-hydraulic proportional

engineering machinery electro-hydraulic proportional valve pilot control and the remote control
Electro-hydraulic proportional valve and other special construction vehicle device technology advances gear, parher metric hydraulic hose fittings steering, braking and other work equipment electrical control systems become a reality. Institutions generally require displacement output similar to Figure 1 can be used to manually scale multi-valve servo control drive is complete. Electrical operation with fast response, flexible wiring, control and integration can be achieved easily with the computer interface, etc., modern engineering machinery hydraulic valve has been an increasing use of electronically controlled electro-hydraulic proportional pilot control valve (or electro-hydraulic switching valve) instead of manually direct hydraulic pilot control operation or multi-way valve. Electro-hydraulic proportional valve (or electro-hydraulic switching valve) Another significant advantage is that construction vehicles can greatly reduce the number of operating handle, which makes the cab simply furnished, can effectively reduce operational complexity, to improve the quality and efficiency of operations have important practical significance. Figure 2 is a TECNORD company JMF type control joystick (joystick), you can use a joystick on Figure 2 multi-chip electro-hydraulic proportional valve and shut-off valve for effective control. The rocker X-axis and Y-axis directions can achieve parher reusable hydraulic hose fittings proportional control or switch control, the application is very convenient.
Digital wireless technology rapid development, the emergence of stable, reliable, suitable for engineering machinery wireless remote control system, remote control layout on mobile machinery receiver receives radio signals can be converted to electro-hydraulic proportional valve control signal and control electro-hydraulic proportional off valve switching signal, and a control signal corresponding to other devices, so that the original manual operation of each component can accept remote commands and the corresponding electrical signal action, this time engineering machinery has actually become a remote control type of construction machinery.
Wireless remote control transmitter and receiver system has been successfully applied to a variety of engineering machinery remote control transformation. From a security point of view, it launched the digital data for each instruction has a set of special system address code, address code that manufacturers used only once. Each receiver only to have the same response address code transmitted signal, the other radio signal is the same parher hydraulic couplers frequency signal receiving apparatus be affected. Plus other security measures adopted to make the system fully guaranteed reliability. Loaders, drilling machines, concrete pumps, truck and bridge maintenance vehicles and other mobile machinery remote control transformation success. Industrial remote control device with electro-hydraulic proportional valve with synergetic, electro-hydraulic proportional valve for construction machinery has provided a workable interface, remote control, remote control also allows electro-hydraulic proportional valve in order to play a greater role.

Hydraulic hose strip actual width, as already mentioned, the theory must be less than the width of the specific value depends on the hydraulic hose nets coverage ratio size.
       Braid angle generally take 30 to 45 in the other parameters is determined, in order to ensure a certain carrying capacity hydraulic hose, braid angle can also be appropriately parher hydraulic hose assemblies reduced. In recent years the introduction of equipment for hydraulic hose seems foreign to the parher flange fitting braiding angle values, the smallest only 15. Value of the size of the braid angle, directly affects the performance of hydraulic hose. If we take the upper limit, is conducive to play it soft features, but can not withstand high loads; if off limits, hydraulic hose can withstand high loads, but not conducive to play its softness properties.
       Nets for hydraulic hose coverage ratio is generally controlled at 75 to 95 percent range, if the value is too large, the repressed hydraulic hose soft characteristics; if the value is too small, will serve to protect the hydraulic hose from knock , touch, grind, hit other parher hydraulic hose assembly mechanical injury. Its value has a direct impact on the size of the performance of hydraulic hose, meaning just the opposite angle weave, if we take the upper limit, hydraulic hose can withstand higher loads, but not conducive to play it soft characteristics; if we take the lower limit value, is conducive to play it soft features, but can not withstand high loads.
      Hydraulic hose steel spindles is generally an even number greater than or equal to 4, the hand-woven, as long as this range are feasible; but mechanical knitting is concerned, on the difficult. Domestic knitting machine setting a fixed number of spindles, and is not adjustable. Therefore, the number of hydraulic hose steel ingot is best knitting machines based on the existing number of spindles to determine.
      At present, the domestic knitting machine with 24, 36, 48, and 64 have been introduced along with the. However, they are designed to weave wire mesh sleeve, weaving out of the "double flower" pattern; while steel braided preferably in the form "single flower" pattern. For this type parher hydraulic quick couplers of weaving machines with slight modifications, can be used to weave steel nets.

hydraulic universal testing machine Precautions

A. Switch sequence:
Since testing machine in Jinan Branch controlled microcomputer control software, should ensure that the testing machine is turned on, the software is not closed.
1 Power on: Open the computer (PC) is flanged fittings turned to open the control software tester power.
(2) Off: Turn off test machine control software shut power off computer (PC) power supply.
Two. Software environment:

III. Showing the value is not displayed:
Please prosecutors testing double hose connector machine and the host computer cable is plugged in, you should ensure that no virtual connection.
Four Note:
1 testing machine key parts (eg: jaw, gearbox, etc.) should always raise grease.
2 computer should be stored in a dry and ventilated room.
3 If you do not use long, once a month should be powered operation.
