The characteristics of mechanical seals are that they can be used for various equipment, especially equipment such as reactors and pumps. Because such equipment has high sealing requirements and cannot enter impurities, it is used more. The problem of water leakage is really worrying. Water leakage causes the sealing effect of the seal to deteriorate. This is something that many people shy away from. The following five tricks can help you easily solve the problem of leaking seals: mechanical seal Reasons for water leakage of mechanical seals: 1. The equipment is too tight. Check the dynamic ring plane of the mechanical seal. If there is a seriously burnt appearance, black plane, and deep marks, the mechanical seal rubber of the pump becomes hard and loses elasticity. This appearance is caused by the over-tightening of the equipment. 2. The equipment is too loose. Check the plane of the dynamic and static rings of the mechanical seal. There is a thin layer of scale on the surface, which can be wiped off, and the surface is basically free of wear. This is caused by the loss of elasticity of the spring and the poor equipment or the axial movement of the motor. 3. Poor water quality. Due to poor water quality, the cartridge-type mechanical seal is rich in small particles and the content of hydrochloride in the medium is high, and the plane or strained surface of the abrasive-wearing mechanical seal has the appearance of grooves and ring grooves. 4. Water shortage operation constitutes dry grinding damage. This phenomenon is more common in the negative pressure at the inlet of the bottom valve type equipment, there is air in the water inlet pipe, and there is air in the pump cavity. After the pump is turned on, the friction of the mechanical seal produces a high temperature during high-speed operation, and cannot be cooled. Check the mechanical seal and the spring tension is normal. , the contact surface is scorched and blackened, and the rubber hardens and cracks. 5. Cavitation. Cavitation mainly occurs in hot water pumps. Since the medium is hot water, the water temperature is too high to generate steam, and the steam in the pipeline enters the high part of the pump cavity. This part of the steam cannot be cleaned, and then constitutes a water shortage operation, the dry grinding of the mechanical seal fails, and the cavitation device automatically discharges. Air valve, switch. The solution to the leakage of mechanical seals: 1. Disposal method: Adjust the height of the equipment. After the impeller is installed, pull the spring with a screwdriver. The spring has a strong tension. 2. Adjust the height of the mechanical seal and the return spring. 3. Improve water pressure or medium, switch the seal. 4. Drain the air in the duct and the pump cavity, and exchange the mechanical seal. 5. Do not use hot water as much as possible. Leakage of mechanical seals is not a trivial matter, and it will lead to failure if you do it wrong, so you must find the cause in time when you encounter this problem. Don't litter. There is also the use of seals under the right conditions. And keep the water clean. Akman Seals is a company specializing in the research, development, and production of mechanical seals. It has a complete range of product models, operates in good faith, and the product quality is guaranteed and trustworthy.

Now that camping chairs have become the standard for professional camping, a suitable camping chair will make your camping life a lot more comfortable, so for beginners, how to choose a camping chair? What parameters should I look for when buying? Let's talk about it today. The selection of outdoor chairs generally mainly depends on two aspects, material, and folding method. Camping Chair Material There are three main places for camping chairs to choose from different materials, brackets, cushions, footpads, and link points. The most common materials for the bracket are iron, steel pipe, aluminum alloy, etc. No matter which material is selected, it is generally treated with anti-corrosion. Perhaps you may have heard that aluminum alloys are relatively light. In fact, this depends on the size of the camping chair and the amount of bracket material used. If the aluminum alloy camping chair is relatively large, the weight is not light. The material selection of the bracket has a certain influence on the load-bearing. The load-bearing of the iron bracket is slightly worse, the steel tube is medium, and the aluminum alloy is the best. When you choose, you must decide which kind of bracket to choose according to your own weight. At present, the cushions of outdoor camping chairs are generally oxford cloth, mesh cloth, oxford cloth + mesh cloth. Generally speaking, the mesh is more breathable in summer, but in any case, the mainstream material in oxford. The materials for the footpads and link points are generally rubber, plastic, etc. Folding method At present, there are two ways of folding camping chairs, one is simple and the other is more troublesome. Let’s talk about the simple first. In fact, it is straightforward to open and fold. It can be completed in 1 second. When storing, squeeze the four feet in the middle, immediately fold it together, and then put it in the storage bag and pack it away. The second one is more cumbersome, a bit like the design style of a tent. It is a bracket spliced together by the bracket rods of the short sections, and then the seat cushion is hung on the bracket. Although it is spliced, it is not a scattered part. There is an elastic cord inside the bracket rod, so whether it is stored or opened, it is quite simple. The good thing is that these camping chairs are generally very portable and miniature when folded. In addition to the folding method and material selection, there are two very important purchase factors, one is the appearance design, and the other is the comfort of use. Generally speaking, the more comfortable the camping chair is, the larger it is. The nicer-looking camping chairs tend to be slightly more expensive. If it is self-driving camping, then when choosing a camping chair, comfort must be the priority. If you are a backpacker enthusiast, when buying a camping chair, the priority is to be lightweight, and the lighter the better, so that it will not be too heavy in the backpack. This type of camping chair is generally foldable, made of aluminum alloy, and the carrying volume is very small. As a reliable and professional supplier of camping chairs, Friday Camp sells high-quality camping chairs at reasonable prices. If you are interested in camping chairs, welcome to consult.

What is a high performance clarifier High-performance clarifier (filter) is an indispensable device on the pipeline of conveying medium. It is usually installed on the inlet side of the pressure reducing valve, pressure relief valve, fixed water level valve, and other equipment of Fanggong's high performance clarifier. The high performance clarifier is composed of a cylinder, a stainless steel filter screen, a sewage part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the high performance clarifier filter, its impurities are blocked. When it is necessary to clean, just take out the detachable filter cartridge and reload it after treatment. Therefore, it is extremely convenient to use and maintain. High-performance clarifier development history Filtration technology has been used in production in ancient China, and paper made of plant fibers was available in 200 BC. In 105 AD, Cai Lun improved the papermaking method. During the papermaking process, he dipped plant fiber pulp on dense thin bamboo curtains. The water is filtered through the gaps of the bamboo curtain, and a thin layer of wet paper pulp is left on the surface of the bamboo curtain, and it becomes paper when it dries. Most of the earliest filtration was gravity filtration. Later, pressure filtration was used to increase the filtration speed, and then vacuum filtration appeared. The high-performance rotary drum vacuum clarifier invented at the beginning of the 20th century realized the continuous filtration operation. Since then, various types of continuous high performance clarifiers have appeared one after another. Intermittently operated high performance clarifiers (such as plate and frame filter presses, etc.) have been developed due to their automatic operation, and the filtration area is getting larger and larger. In order to obtain a filter residue with low moisture content, a mechanically pressed high performance clarifier has been developed. Working principle of high performance clarifier When the high performance clarifier is working, the water to be filtered enters from the nozzle, flows through the filter screen, and enters the pipeline required by the user through the outlet for process circulation. The particulate impurities in the water are trapped inside the filter screen. With such a continuous cycle, more and more particles are intercepted, and the filtering speed becomes slower and slower, while the imported sewage is still continuously entering, and the filter holes will become smaller and smaller, thereby creating pressure between the inlet and the outlet When the large difference reaches the set value, the differential pressure transmitter transmits the electrical signal to the controller, and the control system starts the drive motor to drive the shaft to rotate through the transmission assembly. At the same time, the sewage outlet is opened and discharged from the sewage outlet. After cleaning, the pressure difference drops to the minimum value, the system returns to the initial filtering state, and the system operates normally. The high performance clarifier is composed of a shell, a multi-element filter element, a backwash mechanism, and a differential pressure controller. The transverse partition in the shell divides its inner cavity into upper and lower cavities, and the upper cavity is equipped with multiple filter elements, which has sufficient filtering space and significantly reduced the volume of the high performance clarifier. The lower cavity is equipped with Backwash the suction cup. When working, the turbid liquid enters the lower cavity of the high performance clarifier through the inlet, and then enters the inner cavity of the filter element through the partition holes. The impurities larger than the gap of the filter element are intercepted, and the clean liquid passes through the gap to the upper cavity, and is finally sent out from the outlet. The high performance clarifier uses a high-strength wedge-shaped filter screen to automatically clean the filter element through pressure difference control and timing control. When impurities in the high performance clarifier accumulate on the surface of the filter element and cause the inlet and outlet pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends a signal to drive the backwash mechanism. When the backwash suction cup port is directly opposite to the filter element inlet, the drain valve is opened, and the system discharges pressure at this time. A negative pressure zone appears on the inside of the suction cup and the filter element whose relative pressure is lower than the water pressure outside the filter element, forcing part of the net circulating water from the outside of the filter element Flowing into the inner side of the filter element, the impurity particles adsorbed on the inner wall of the filter element flow into the drum with water and are discharged from the drain valve. The specially designed filter screen produces a spray effect inside the filter element, and any impurities will be washed away from the smooth inner wall. When the pressure difference between the inlet and outlet of the high performance clarifier returns to normal or the timer setting time is over, the material flows continuously during the whole process, and the backwash consumes less water, realizing continuous and automated production. high performance clarifiers are widely used in the fields of metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, and urban water supply. Such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration treatment, continuous casting water system in the metallurgical industry, blast furnace water system, high-pressure water descaling system for hot rolling. It is an advanced, efficient and easy-to-operate automatic filter device. The water to be treated in the high performance clarifier enters the body through the water inlet, and the impurities in the water are deposited on the stainless steel filter screen, resulting in a pressure difference. The pressure difference between the inlet and outlet is monitored by the pressure difference switch. When the pressure difference reaches the set value, the electronic controller feeds the hydraulic control valve and drives the motor signal. After the equipment is installed, the technicians will debug and set the filtration time and the cleaning conversion time. The water to be treated enters the body from the water inlet, and the high performance clarifier starts to work normally. When the preset cleaning time is reached, the electric controller will provide hydraulic power. The control valve and drive motor signal trigger the following actions: the motor drives the brush to rotate to clean the filter element, while the control valve opens to discharge the sewage. The entire cleaning process only lasts for tens of seconds. When the cleaning is over, the control valve is closed and the motor stops. Turning, the system returns to its initial state and begins to enter the next filtration process. The shell of the high performance clarifier is mainly composed of coarse strainer, fine strainer, suction pipe, stainless steel brush or stainless steel suction nozzle, sealing ring, anti-corrosion coating, rotating shaft, etc. Separating the container into upper and lower chambers with filter media constitutes a simple high performance clarifier. Suspension is added to the upper cavity, and enters the lower cavity through the filter medium under pressure to become filtrate. The solid particles are trapped on the surface of the filter medium to form filter residue (or filter cake). During the filtration process, the filter residue layer on the surface of the filter medium gradually thickens, the resistance of the liquid through the filter residue layer increases, and the filtration speed decreases. When the filter chamber is full of filter residue or the filtering speed is too low, stop filtering, remove the filter residue, and regenerate the filter medium to complete a filtration cycle. The liquid must overcome the resistance to pass through the filter residue layer and the filter medium, so there must be a pressure difference on both sides of the filter medium, which is the driving force for filtering. Increasing the pressure difference can speed up the filtration, but the deformed particles under pressure will easily block the pores of the filter medium when the pressure difference is large, and the filtration will slow down instead. Suspension filtration has three methods: filter residue layer filtration, deep layer filtration and sieving filtration. ① Filtration of the filter residue layer: the filter medium can only retain large solid particles at the initial stage of filtration, and the small particles pass through the filter medium with the filtrate. After the initial filter residue layer is formed, the filter residue layer plays a major role in filtering. At this time, both large and small particles are retained, such as the filtration of a plate and frame filter. ②Deep filtration: the filter medium is thicker, the suspension contains less solid particles, and the particles are smaller than the pores of the filter medium. When filtering, the particles are adsorbed in the pores after entering, such as the filtration of porous plastic pipe high performance clarifiers and sand filters. ③Screening: The solid particles retained by the filter are larger than the pores of the filter medium, and the inside of the filter medium does not absorb solid particles. For example, a rotating drum filter screen filters out coarse impurities in the sewage. In the actual filtration process, the three methods often appear simultaneously or one after another.
