How to use cable hydraulic tongs, how to use hydraulic tongs How to use hydraulic tongs

The correct use of hydraulic pliers is as follows:

The first step is to determine whether the diameter of the hydraulic tong is the same as the outer diameter of the acoustic tube. Only by choosing the right size, the hydraulic clamp can be just aligned with the pipe body, so as to ensure the use strength of the hydraulic clamp, and it must be checked.

2.The second step is to install, and after confirming the specifications of the hydraulic clamp and the acoustic tube body, what needs to be done is to loosen the pressure relief valve first. Then, remove the jaw bolts and loosen the jaws of the hydraulic pliers, clamping the ends of the acoustic tube.

3.The third step is the clamping, using the long handle of the hydraulic pliers to crimp until the crimping jaws touch. Then crimp again near the crimp until the connections at both ends are fully compressed, then release the pressure relief valve.

4.The fourth step is to check, for the tightness of the connection, after the completion of the connection, you can use the method of filling water into the pipe body to check whether the pipe body is seeping. If there is a water leak, you can continue to tighten it.

First, select the matching crimping die according to the wire diameter of the cable, and loosen the pressure relief valve, which is generally on the right side;

2. After stripping the insulation layer of the cable according to the length of the copper (aluminum) pipe, the copper (aluminum) pipe is sleeved on the core wire with the insulation layer removed.

3. Put the hydraulic pliers of the selected crimping die on the end without a wiring nose on the copper (aluminum) pipe, tighten the pressure relief switch, put the crimping die outward and then start crimping, crimp until the two crimping dies collide, and then relieve the pressure. Continue to crimp in the place next to the crimp, generally crimp 4 5 places, this depends on the quality of your copper (aluminum) pipe.

Fourth, after the crimping is completed, use pliers or flat files to remove the burrs generated by the crimping, polish them smoothly, and do a good job of insulation!

The crimping plier is composed of an oil tank, a power mechanism, a reversing valve, a pressure relief valve, and an oil pump mechanism, and the oil pump mechanism is composed of an oil pump body, a high and low pressure oil outlet hole, an eccentric shaft, an eccentric bearing, a driven gear and a pair of high-pressure oil pumps and a low-pressure oil pump, the oil pump body is suspended on the oil tank cover, and the high and low pressure oil outlet holes are set up on the oil pump body, and the pressure relief valve oil circuit is connected, the eccentric shaft is longitudinally arranged, the upper end pivot is placed in the oil pump body, and the lower end is fixed with an eccentric bearing.

The principle of omission in the model: copper is the main conductor material used in wire and cable products, so the copper core code T is omitted, except for bare wires and bare conductor products. Bare wires and bare conductor system categories, power cables, magnet wire products do not indicate the category code, electrical equipment wires and cables and communication cables are not listed, but the sub-category or series code is listed.

The manufacturing delay of wires and cables is completely different from the production method of most mechanical and electrical products. Mechanical and electrical products are usually assembled into parts from another part, and multiple parts are then assembled into a single product, and the product is measured in units or pieces. Wires and cables are measured in terms of length.

All wires and cables are made from conductor processing, and insulation, shielding, cable, and sheath are added layer by layer on the periphery of the conductor to make wire and cable products.

1. First of all, select the matching crimping die according to the diameter of the cable, and loosen the valve for pressure relief, generally on the right side.

2. Strip the cable according to the length of the copper (aluminum) pipe to remove the ear of the sun-edge layer, and put the copper (aluminum) tube on the core wire that has been stripped of the insulation layer.

3. Put the hydraulic pliers of the selected crimping die on the end without a wiring nose on the copper (aluminum) tube, tighten the pressure relief switch, put the crimping die outward, and then the Xunzu chain starts crimping, and crimps until the two crimping dies collide.

4. After the crimping is completed, use pliers or flat files to remove the burrs generated by the crimping, polish them smoothly, and do a good job of insulation.

Rechargeable hydraulic pliers are currently the most lightweight design of cordless hydraulic tools, can be operated with one hand, used in power distribution terminal crimping, lightweight, high durability, maintenance probability is the lowest for all hydraulic tools, reach the set pressure automatic pressure relief, the head can be rotated for different workplaces, mechanical hydraulic head to ensure the quality of crimping.

10.Large-tonnage hydraulic tongs are called split hydraulic tongs, which are commonly known as hydraulic compression tools in the world, and are used with pumps (hand pumps, foot pumps, and electric hydraulic pumps).

Hydraulic pliers are professional hydraulic tools specially used for crimping cables and terminals in power engineering.

According to its structural form, hydraulic tongs can be divided into integral hydraulic tongs and split hydraulic tongs. The integrated design of the integral hydraulic tong function module and power module is small in size, light in weight, easy to carry, and suitable for temporary small operations such as out-of-office repairs. The function module of the split hydraulic clamp is separated from the power, and it is connected to the power through accessories such as oil pipes, which can be manual or electric, which is very flexible.

According to the function, it can be divided into hydraulic crimping pliers and hydraulic cutting pliers, hydraulic crimping pliers are used for various crimping operations, such as copper and aluminum terminal crimping, willow nail riveting, etc.; Hydraulic cut-off pliers are used for cutting off various materials, such as rebar, cables, etc.

Precautions for use.

1. Before starting the hydraulic clamp, first check whether the high-pressure pipe joint and nut connected to the oil cylinder and the pump station are tightened, so as not to fall off and hurt people. When suspending construction, do not disassemble the connecting hose, and clean each joint before maintenance and construction. In order to prevent dust from entering the hydraulic oil circuit, damaging the hydraulic oil circuit, damaging the hydraulic components in the hydraulic system, such as pumps, valves and cylinders.

2. Before the oil pump starts, check whether the oil level is above the center line of the oil standard, and if there is a shortage of oil, it should be replenished in place first to prevent the oil pump from being emptied. When refueling, the 120 filter screen should be used to filter out the impurities in the oil, and the oil filter should be cleaned once every month, and the oil tank should be cleaned once every three months, and the oil should be replaced with new oil at the same time.

3. Before the motor starts, the manual reversing valve (three-position four-way rotary valve) should be placed in the middle position (the oil does not enter the oil cylinder but directly enters the oil tank), so as to avoid the oil pump starting with load. First jog the motor several times, and then turn the reversing valve to supply oil to the system when the pump suction is normal.

4. The commonly used hydraulic oil for the pumping station is YB-N32, which can be changed to YB-N22 when the ambient temperature is lower than 10, and YB-N46 can be changed when the ambient temperature is higher than 40.

5. The normal working temperature of the hydraulic system is 20-50, when the temperature is too high, cooling is required, and when the oil temperature is too low, heating measures or an idle oil pump without load are required to increase the oil temperature.

6. The high-pressure tubing will age after long-term use, and the user should check it frequently. In high-pressure experiments, leaks, bulges, or blasts must be replaced. In addition, when using the high-pressure oil pipe, avoid discounting or sharp bends, and do not get too close to the hose to prevent blasting and throwing off people.

7. The pump should be overhauled once every six months, all the accessories on the pump should be cleaned with kerosene, and attention should be paid to protecting the surface of each match, not arbitrarily bumping, and the moving parts should move flexibly after assembly, without local jamming.

8. Before handling the equipment, it is necessary to check whether the handle is moving, whether the ring connection is reliable, and there must be sufficient working space during construction to prevent injury or damage to the equipment.

Hydraulic pliers can cut a very thick diameter of more than 20mm steel bar, by hydraulic push piston rod front section of the shear blade to achieve shear force, the use of a liquid flow channel through the plunger to the hydraulic cylinder body pressure oil, when the steel bar is sheared, there is an oil return valve to open the piston rod automatically return.

Hydraulic pliers are used to cut down rebar or something. You watch what the TV says about firefighters who rescue who with hydraulic tongs. Watch more of the news haha.
