torque screwdriver main features

Our company has introduced a precision torque screwdriver, having earlier set torque screwdriver preset function, its main features are:
1. The force value is displayed: the scale and the sub scale of the ring on the upper sleeves comprehensive instruction torque value reading aspect, accurate, high-precision
2. The right and left reversed, clockwise and counterclockwise twist
3. Reasonable design, hand-held operation, prolonged use
4. Simple operation, set the desired value, the same way anyone can operate using
5. Enclosed Phillips and flathead screwdriver

The Use notes of hydraulic jack

Hydraulic jacks Caution:
1: hydraulic jack at the lifting operation, to select the appropriate tonnage hydraulic jacks: the carrying capacity can not overload the carrying capacity of hydraulic jacks choose must be greater than 1.2 times the weight of gravity; hydraulic jack minimum height appropriate, in order to facilitate removal, use The minimum height of the hydraulic jacks should headroom weights at the bottom urging adapt the process when landing pad support heavy sleeper, hydraulic jack lifting height greater than the thickness of the sleeper of sleepers and deformation.
2: If you use multiple Pancake Lock Nut jacks lifting the same equipment, the same model should be used hydraulic jacks and hydraulic jacks each rated lifting capacity of the device and not less than the assumed 1.5 times gravity.
3: hydraulic jacks should be wiped clean prior to use, and should check the parts are flexible, without injury, when there is a load should not remove the quick connector, to avoid accidents and damage to components.
4: Before using hydraulic jacks should be placed flat, not tilted to pad the bottom level, to prevent ground sinking or partial load shift tilt or tip over leaving the hydraulic jack, the jack at the bottom of the pad can be tough in the hydraulic pillow surgery or steel to expand pressure area to prevent slip and fall or accident; do not use wood or steel with oil as a liner, when the force to prevent slipping accidents; weight is lifting position must be safe, solid site to preventing damage to the device.

Mechanical properties synchro flange separator

Flange separator is the separation of large industrial machinery equipment, divided into one hydraulic flange separator and the split flange separator. Mainly used for pipeline maintenance, replacement pipeline construction, testing and flanges, maintenance pads, pressure vessel, cylinder head open, power plants, bearing removal, electricity and oil drilling, rotor removal, offshore platforms, lifting work, shipbuilding, industrial equipment, horizontal movement of the workpiece and other industry sectors. Mechanical synchro flange separator characteristics are as follows:
1. Suitable for repair, overhaul, testing and valve replacement applications.
2. The overall concept of separation: no friction, smooth motion parallel to eliminate the risk of damage and separation wedge flange damaged.
3. Unique interlocking wedge design of the first stage without bending without slipping hazard.
4. Insert opening required size only 6mm.
5. The level design so that each row cantilever frame steps Jieke bear full load.
6. fewer moving parts, durable, easy maintenance.

Electric hydraulic pump station features

Electric hydraulic pump station features:
1.spray painted surface, anti-corrosion, strong tolerance ability.
2.Compact and lightweight design, weight light to shift transport.
3.The two-stage pump design, low pressure high flow, fast motion when the actuator load, high and low voltage automatic switching.
4.The high-pressure flow, for supporting the use of large tonnage hydraulic jack.
5.The standard adjustable pressure valve, easy to re-calibrate the work pressure and prevent pressure overload.
6.Standard motor starters, overload and leakage protection.
7.durable valve for single-acting and double-acting jack, the choice of solenoid valve can be remote operation; PLC control options.

How electric hydraulic pump works

Electric hydraulic pumps are relying on the principle of sealed volume changes to the work, it is generally referred to as displacement pump plunger mounted in the cylinder block forming a sealed volume under the action of the spring plunger is always pressed against the eccentric wheel. Prime mover driven eccentric rotation of the plunger reciprocates, so that the size of the sealed volume occurs periodically alternating. When the plunger from small to large, a partial vacuum is formed, so that the oil tank at atmospheric pressure effect, the suction tube to open the top one-way valve into the oil chamber and achieve suction; conversely, when the plunger from big-hour, suction chamber full of oil will top one-way valve opening pressure of the oil flowing into the system implementation. Such pump on the prime mover input mechanical energy into fluid pressure energy, the prime mover driven eccentric constant rotation, the hydraulic pump on the suction and pressure oil continuously.
