German SAF-FRO tools SAF-FRO models SAF-FRO prices

SAF-FRO tools are made of copper alloy. Due to the good thermal conductivity of copper and its characteristic of being almost carbon-free, the heat generated in a short time when the tool rubs against or impacts an object is absorbed and conducted. Another reason is that copper itself is relatively soft, providing good compliance during friction and impact, making it difficult to produce tiny metal particles. As a result, we hardly see any sparks, so explosion-proof tools are also called non-sparking tools. The materials for explosion-proof tools are beryllium bronze and aluminum bronze. Beryllium bronze alloys and aluminum bronze alloys do not spark upon impact or friction, making them very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic, and corrosive environments. BeA-20C alloy withstands an impact energy of 561IJ in hydrogen containing 30% or in methane-air-oxygen mixture containing 6.5-10%, without sparking or ignition after 20 impacts.

SAF-FRO tool applications and usage

The electric hydraulic oil pump can serve as the hydraulic pump for various hydraulic devices. When equipped with other hydraulic tools, the electric hydraulic oil pump can perform tasks such as lifting, pressing, pipe bending, bar bending, straightening, shearing, assembly, and disassembly, reducing labor intensity and improving work efficiency. During use, open the air release nut, turn on the switch on the oil collection block, plug in the power supply, and connect the quick coupler to the quick connector on the corresponding hydraulic device. Press the power switch; after the motor runs for 1-2 minutes, turn off the switch to set it to the pressure-boosting state. At this point, the output hydraulic oil will perform various tasks, self-pressurizing as the load increases until reaching 63MPA. After work is completed, open the switch to relieve pressure. Once the hydraulic oil has returned, remove the quick coupler, tighten the air release nut, unplug the power cord, and close the switch.

SAF-FRO tool purchasing guide

1) Distinguish between household and professional use based on needs. Most power tools are designed for professionals. When purchasing, differentiate between professional and general household tools. The difference usually lies in power; professional tools have higher power to help professionals reduce workload, while household tools require less input power as the projects and workload are smaller. 2) The outer packaging of the tool should have clear patterns, no damage, a sturdy plastic box, and durable latches. 3) The appearance of the tool should have uniform color. The surface of plastic parts should have no visible flow marks or dents, and there should be no scratches or collision marks. The assembly misalignment between housing parts should be ≤ 0.5mm. Aluminum casting coatings should be smooth, aesthetically pleasing, and undamaged. The entire machine surface should be free of oil and stains. When held by hand, the switch handle should be flat. The length of the power cable should generally be no less than 2 meters. 4) The nameplate parameters of the tool should match those on the CCC certificate. The manual should include the detailed address and contact information of the manufacturer and production factory. The nameplate or certificate of conformity should include a traceable batch number. 5) Hold the tool, connect to power, and frequently operate the switch to start the tool repeatedly. Observe whether the on/off function of the tool switch is reliable. Simultaneously observe whether there are any abnormalities in nearby televisions or fluorescent lights to confirm if the tool is equipped with an effective radio interference suppressor. 6) Run the tool for one minute. While running, hold it by hand; you should not feel any abnormal vibration. Observe the commutation sparks; the commutation spark level should not exceed 3/2. Generally, looking inward from the air inlet of the tool, there should be no obvious arcing on the commutator surface. There should be no abnormal noise during operation.

SAF-FRO tool types and features

Hydraulic tools include: hydraulic wrenches, electric pumps for hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, hydraulic pullers, etc. Hydraulic tools offer the advantages of high efficiency and convenience. 1) They generally use mineral oil as the working medium, allowing self-lubrication of relative moving surfaces and resulting in a long service life. 2) Lightweight, compact, low motion inertia, and fast response speed. 3) Various hydraulic transmission components can be arranged conveniently and flexibly according to needs. 4) Overload protection can be automatically achieved. 5) Operation and control are convenient, enabling wide-range stepless speed regulation (speed regulation range up to 2000: 1). 6) Linear motion is easily achieved. 7) Machine automation is easily realized. When using electro-hydraulic combined control, not only can a higher degree of automatic control be achieved, but remote control is also possible.
