Hydraulic universal testing machine is generally
hydraulic universal testing machine classification
Hydraulic universal testing machine is generally 100KN, 300KN, 600KN, 1000KN four categories, as opposed to a wide variety of electronic universal testing machine is relatively simple; [2]
Jinan Smartech hydraulic universal testing overband magnetic separator machine in this technically refined into three categories of 12 kinds of conventional type:
Digital Display (LCD) hydraulic universal testing machine: 100KN, 300KN, 600KN, 1000KN
Screen display (computer display) hydraulic universal testing  machine: 100KN, 300KN, 600KN, 1000KN
Computer control (automatic) hydraulic universal testing machine: 100KN, 300KN, 600KN, 1000KN
According to intensify its way to distinguish generally two kinds: manual and hydraulic
Screw adjustment under Neodymium Magnet way into (the most common): chain-and worm-type
Depending on the device is divided into grade: B type, C-type and D-type machine and dryer 1990s A-type machine (have been eliminated)
Note: In addition to the outside type A, B, C, D are the fuel tank mounted under the host

the general composition of the hydraulic system
A complete hydraulic system consists of five parts, namely, stainless steel hydraulic fittings hydraulic power units, actuators, control components, auxiliary components (accessories) and hydraulic oil.
Power Components
The role of the hydraulic power unit is the original motivation mechanical energy into pressure energy of the liquid, pump means in the hydraulic system, which provides power to the entire hydraulic system. Hydraulic pump structure generally have gear pumps, vane pumps and piston pumps.
Implementation of components (such as hydraulic cylinders and hydraulic motors) the role of the fluid pressure energy is converted to mechanical energy to drive the load for linear reciprocating or rotary motion.
Control element (i.e. various hydraulic valves) in the hydraulic system to control hydraulic adapter fittings and regulate fluid pressure, flow and direction. According to the different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valve is divided into benefits flow valve (safety valve), reducing valves, sequence valves, pressure relays, etc.; flow control valve includes a throttle valve, regulating valve, flow diversion valve; directional control valve includes a check valve, check valve, shuttle valve, valve and so on. According to the control in different ways, hydraulic valves can be divided into switching control valves, control valves and constant proportional control valve.
Auxiliary components including fuel tanks, filters, tubing and fittings, seals, hydraulic manifold, quick coupler, high pressure ball valves, hose assemblies, pressure joints, pressure gauge, oil level, oil temperature meter, etc..
Hydraulic oil is the hydraulic energy transfer system working medium, hydraulic testing machine a variety of mineral oil, emulsion oil hydraulic molding Hop categories.
hydraulic parts of the advantages of efficient and durable
With the economic development and civil aviation Wuhan Flights to increase oil supply, refueling apron pipeline has become the main mode of refueling aircraft. To ensure proper lubrication, hydraulic manifold normal use and quick maintenance depot device management has become a top priority task.
The use of pipeline pump points:
1) test work: Check for loose connections; hand plate number of revolutions of the rotor dynamic coupling ring, watch crew rotation is flexible, whether there was a noise, and the severity of uneven feeling, to determine whether there is any foreign matter or the pump shaft is bending,hydraulic valve manifold  seals installation is not correct, etc.; inspection seal cavity clean the 20th lubricants are filling 1/2 cavity space; pump unit surface is clean; steering unit load tests.
2) Manually start: irrigation pump (first time), slightly open the outlet valve, start the motor, pump pressure rises and recognized as smooth involute when the outlet valve to working conditions.
3) Run tests: the pump frequency (frequency) during normal operation, you should regularly check and record the pump ammeter, voltmeter, import vacuum gauge, pressure gauges and flow meters, such as hydraulic valve block instrument readings. Unit vibration, noise, temperature, etc. are normal. Shaft seal should not have significant fuel leak.
4) Normal Parking: close the discharge valve, the pump light load, stalling the motor.
5) Emergency stop status:
⑴ pump motor operates ammeter indicates abnormal (too large or become scarce); pump system is making an unusual sound.
⑵ pump inlet vacuum gauge, outlet pressure gauge anomaly, and issued a larger pump threaded adaptors different sound vibrations, severe performance degradation.
⑶ pump motor odors, aviation fuel leaking shaft seal and bearing temperature exceeds 75 degrees and so on.
Pipeline pump quick maintenance points:
1) every 500 hours of operation, loosen the seal seat plug, use a syringe hydraulic circuit block oil residues; qualified to seal cavity filling machine oil to the 20th volume of the cavity half (plus the right amount of oil inspection methods: Run pump, oil can not emerge out); plug tightened to prevent leakage phenomenon.
2) that the motor mechanical noise increased and abnormal temperature rise of the bearings, check motor bearing lubrication. Such as grease discoloration, dirty should be replaced.
3) When they find there is leakage sealing seat, you can release the seal seat plug, run the pump with oil smoke outside and have a taste of aviation fuel when you can determine: mechanical seal failure. Stop using the pipeline pump mechanical seal for quick replacement manifold.
4) Replace the mechanical seal failure approach:
(1) Place pump parts ready workbench (ground) and disassembly tool, do not mess with any of misplacing avoid damage the pump components.
(2) Confirm the motor is removed overhaul state; unscrew the oil drain plug, use a straw to suck oil seal seat cavity out.
(3) remove the split couplings: first fixed coupling Unscrew the socket head cap screws, then gently push the coupling half from the shaft slowly down (be careful not to fall off). Unscrew the shaft with a wrench fasten bolt and block, so slowly sink to the pump impeller, remove the other half of the coupling, scored shaft rings.
(4) split seal seat: Unscrew the sealing seat clamp nut, gently remove the manifold sealing seat (Note: Do not break the seat rubber seal) and clean.
(5) Remove and clean the bearing: to gently loosen the bearing bolts after removal from the top with a bearing, and put up along the shaft and remove; using jet fuel, cleaning bearings and pedestal, dried and mounted ago Lightly No. 20 machine oil lubrication protection.
(6) Remove the mechanical seal: Seize the seal spring put up along the shaft, teflon hose can be demolished.
(7) Mechanical seal assembly: In the dynamic and static ring mirror coated with clean oil, No. 20; guide bearing cast lubricants, first locate the stationary ring gently into the guide bearing; longer on the pump shaft cast lubricants, the part of the mechanical seal ring gently into the shaft by hand should be able to push the seal ring retractable (Note that static and dynamic part of the anti-rotation ring parts to be fitted in place).
(8) mounted seal seat: seal seat into the rubber seal first, then seal seat into the pump cover and the pressure in the bearing housing, tighten the nut.
(9) fitted couplings: first head mounted on the motor shaft ring, and put on half of the coupling, and then in the end and the coupling shaft stopper fitted tank and tighten the bolts with a wrench (lift shaft 3 ~ 5 mm and provides mechanical seal prestressed); then fitted screw on the other half of the coupling socket head cap screws must be tightened. Install the coupling proper inspection requirements: the split coupling gap down evenly; hand inspection plate moving rotating flexible couplings few laps.
(10) by the use of point commissioning check and replace the mechanical seal is correct pump is operating correctly.
Practice has proved that we are on the proper use of the above methods, rapid maintenance pipeline pumps, pipelines to guarantee that the airfield refueling system as the core equipment in normal operating state; through frequency control, you can try to play it smooth, energy efficient, long-term durability advantages for Miles voyage continuous supply high-quality aviation fuel.
