  As we all know, the main purpose of the design and development of rollover  road blockers  is to guard and manage the entrance gates of sensitive and key units and prohibit unauthorized vehicles from forcing their way in. The hydraulic rollover roadblock machine is like a solid wall. Besides being practical, it is also very reliable and safe.  ZASP  presents you a guide to the use of road blockers. Advantages 1.Fast and calm Lifting time up to 3 seconds, far more than the same size pneumatic lifting road blocker, very valuable. Its hydraulic drive unit moves softly, no more traditional pneumatic lift road block due to the noise of air pump. 2. Control agility The control unit adopts multi-function logic controller, which can modulate many different function modes to meet the different function needs of different users, and the movement stroke can be timed to save energy. 3. Safety and reliability In case of emergency, such as power failure, it can be manually ...

    Whether you work in construction, government or entertainment,  purchasing barricades  requires some familiarity with barricade features and variations. While barricades seem standard, certain features make more or less sense depending on your specific crowd control experience. Do you need barricades that will survive outdoor weather and hard rain? Will they need to be sturdy on uneven ground? Will the crowd need an access point through the barricades? Will these barricades be permanently fixed, or will they have to be moved and stored? These are key considerations when comparing the different  barricades for sale . Here are some things to keep in mind ahead of buying steel barricades: Barricade Types: Metal barricades are categorized by the exterior coating and feet design. Barricade Compatibility: Barricades are built to last. When you need to buy more barricades, you must consider features for compatibility. Variati...

  Choosing the right  pump  for your slurry application can be a daunting task due to the balance of many factors including pressure, flow rate, abrasiveness, viscosity, particle size and particle type. There are several  types of pumps  suitable for  pumping slurries , but there are some important factors to consider before deciding which technology to use. You can follow these four simple steps to determine which type of slurry pump is best for your particular application. 1. Determine the Nature of the Material Being Pumped Consider the following. Size, shape and hardness of the particles (which affect the potential for wear and corrosion of the pump components), corrosiveness of the slurry. 2. Consider the pump components If it is a  centrifugal pump , is the design and material used to manufacture the impeller adequate to pump the slurry? What types of materials are used to manufacture the pump? Are the pump discharge components suitable for the s...

  High-activity dry yeast for feed is the use of modern biotechnology and advanced equipment to dry the yeast cells produced on an industrial scale into a product with more than 95% dry matter and less than 5% moisture, and vacuum packaging. When it sees water, it instantly becomes a physiologically active cell, so it is also called instant  active dry yeast . High-activity dry yeast for feed is a dormant state of plasmolysis made by low-temperature drying through a special process. It can be quickly resurrected when it encounters water and O2 in the outside world; its resurrection time is very short. High active dry yeast for feed has the advantages of low water content, quick rejuvenation, long storage time and convenient use. Numerous studies have shown that feeding highly active dry yeast has a positive effect on the activity of ruminant microorganisms in ruminants, as well as the ability to stabilize rumen pH, prevent rumen acidosis, stimulate the growth of fibrous degrad...

  Some indoor home gyms rely on carpeting or vinyl for the flooring, which could temporarily suffice if you’re on a budget and must use what’s already there. However, carpet and vinyl aren’t shock-absorbent (for your joints or the weight plates) or super durable. Soft carpet can be a safety issue, too, as it lacks stability and support. And carpet can collect sweat, dust, mold, and (worst of all) the ungodly residue of a knocked-over shaker bottle of protein pow-pow. Spill one of those on your carpet and you may as well just put your house up for sale. OK, so maybe ixnay on the arpetcay. That’s why many people choose to lay special flooring in their home gyms. Most gym flooring is made from rubber, because it can absorb impact, doesn’t dent or scratch like wood, and is more resilient than foam. An example is the  custom gym floor mats , made from a high-quality rubber that doesn’t absorb moisture, making it resistant to bacteria growth (and whatever nightma...

  Globe valves  are linear motion closing-down valves in which the closure member is moved squarely on and off the seat. Usually the closure member is referred as a disc, irrespective of its shape. The seat opening varies in direct proportion to the travel of the disc. This proportional relationship between valve opening and disc travel is ideally suited for duties involving regulation of flow rate. Globe valves are most suitable for throttling and controlling fluid flow and are generally employed in small size piping.   Globe valve design necessitates two changes in the direction of flow and this causes resistance in liquid lines and objectionable pressure drop. The installation of globe valves is made so that the flow is up through the seat ring and against the bottom of the disc. This prevents accumulation of dirt and debris above the disc.     Globe valves may be used for most duties encountered in fluid handling process piping systems. Although the globe va...
