In the era of traditional farmers, the easiest and cheapest way of transportation is manpower. Those from well-off families will use camels, cows and donkeys to assist in consignment. Due to limited energy, we cannot handle more cargo in a short time. Over time, various inventions came into being. Although the handling efficiency has been greatly improved, high-altitude operations have not been effectively solved.
Vacuum spreader came into being…
Simply speaking, vacuum spreader stores vacuum energy in the vacuum accumulator, which can be transferred to the suction cup within one second so as to be absorbed instantly. Vacuum spreader mainly relies on the vacuum source to vacuum the air inside the suction cup to generate vacuum. Generally, the suction cup is made of silica gel, natural rubber, nitrile butadiene rubber, etc. Nowadays, vacuum spreader is widely used in the construction industry. By changing the material of suction cup, different materials can be absorbed, and materials such as plate and glass can be handled or loaded without damage.
Vacuum is created by vacuuming the air in the suction cup and draining away the atmospheric pressure of 1kg/cm2 (950~ 1050mbars). We can get 10,000 kilograms of pressure on a 1m2 suction cup. This physical fact leads to a very efficient transport system.
So what are the advantages of using a vacuum spreader? There are at least the following four main advantages:
1. Fast operation
The vacuum energy is stored in the vacuum accumulator, and it can be transferred to the suction cup within one second and absorbed instantly
2. Safe adsorption, no damage to the surface of the material
The vacuum spreader mainly relies on the vacuum source to evacuate the air inside the suction cup to generate a vacuum. Generally, the suction cup is made of silica gel, natural rubber, nitrile rubber, etc., which can realize the non-damaging handling or loading of materials such as plates and glass.
3. Safe to use
The vacuum of the spreader usually comes from an accumulator. In the event of a vacuum pump power failure, the energy reserve can maintain the load for several hours. The degree of vacuum is controllable. The sensor can show the system in case of leakage and load release. As long as there is a proper vacuum in the suction cup, the load will not fall. It’s just a physical law.
4. Save time, effort and cost
The use of vacuum spreaders can reduce the number of employees in the storage area. The absorption and release can be done by only one person: the driving operator. In any case, it is necessary to reduce the number of workers engaged in hard and dangerous work.
Since the handling of the vacuum device is very fast, cost savings exist in the speed. The vacuum handling system does not leave marks on the product, so it can handle materials that need to be handled carefully.
5. Easy to operate
Since the operation of the vacuum spreader is on the top, it becomes easier to grab, put down and release. This is also one of the main advantages of using vacuum spreaders to carry things.
The components of the vacuum spreader include: vacuum suction cup, vacuum pump, pressure gauge, etc. Pay attention to maintaining the suction cup and choosing an efficient vacuum pump to extend the service life of the spreader. Among them, vacuum pump as the core component of the vacuum spreader, how to choose?
The vacuum pump provided by Shanghai Kanter Vacuum Technology Co., Ltd. can meet the needs of vacuum packaging machines of different models/different sizes. Common vacuum pumps are:
The vacuum pump provided by Shanghai EVP Vacuum Technology Co., Ltd. can meet the needs of different models/different sizes of vacuum spreader, Common vacuum pumps is:
SV Rotary vane vacuum pump, the ultimate vacuum is 50-200pa, and the capacity is 8m3/h-300m3/h.
The selection of rotary vane pump model is also based on the size of the vacuum spreader. EVP Vacuum has extensive experience in vacuum spreader, please feel free to communicate any questions.
