Q:How do you determine the assembly direction of the cylinder seals?: The lip of the cylinder seal is generally facing the direction of the oil pressure, so that it can play a sealing role in the work process.

Q:What tools are needed to replace the water seal for the air conditioning pump? What's the name?: Four. Inspection of mechanical seal before installationBefore assembling the mechanical seal, the moving ring, the stationary ring, the shaft sleeve and other parts should be thoroughly cleaned. Key examination:1. whether there is any scratch, crack and other defects on the surface of the dynamic ring, these defects will cause serious leakage of the mechanical seal.2. check whether the static ring seat affects the sealing defects. Such as static and dynamic ring seat and dynamic ring seal apron, with the presence of defects such as scars.3. check whether the mechanical seal spring is damaged or deformed and whether the coefficient of rigidity changes.4. check the sealing sleeve whether there is burr, groove mark and other defects.5. sweep check all seal aprons whether there are cracks, holes and other defects, measuring whether the rubber ring diameter in the range of work.6. pump mechanism of mechanical seal, but also to check whether the spiral of the spiral pump cracks, broken wires and other defects.

Q:The function and principle of cooling water for mechanical seal of water pump?: Mechanical seals, in order to protect the sealing surfaces of the moving and stationary rings, require cooling to cool them,There are two forms of cooling, a pump fluid leaking into the mechanical seal, which is relatively dead water,

Q:Does the PTFE seal contain plasticizer? Does the silicone seal require temperature during use?: At the same time, PTFE has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used as lubrication, but also become an ideal coating to clean the inner layer of the water pipe.Most of the PTFE material contains plasticizers.

Q:About the service life of hydraulic cylinder sealing ring: 24 hours, non-stop use, in addition to the temperature, there are friction, so generally 3 to 5 months, personally, there is no specific definition, depending on the environment, the use of frequency, temperature. Medium. Etc..

Q:What's the difference between the oil seal and the seal?: Skeleton oil seal, TC import oil seal and domestic oil seal, the main difference has the following key places, materials, imported oil seal material and formula used to produce the product quality is better than the current domestic oil seal

Q:What is the sealing principle of O type sealing ring?: Type O sealing ring is a sealing extrusion type, the basic working principle of extrusion type seal is the seal on elastic deformation caused by contact pressure in the sealing contact surface, the contact pressure is greater than the sealed medium pressure, no leakage, and leakage.

Q:Silicone seals should pay attention to what storage?: 4. Seals should not be placed near heat sources, motors, or ozone.5, do not use wire, rope hanging seals, so that storage will make the seal deformation, damage to the lip.The above is the silicone rubber seal storage should pay attention to several aspects, want to know more about silicon rubber tube knowledge

Q:What are the requirements of bearings for sealing?: Bearing seal:Sealing: to prevent dust, water, and other debris from entering the bearings and to prevent lubricant loss.The seals of rolling bearings are generally divided into contact seals, non contact seals and combined seals

Q:Why can't polyurethane seal be used as hydraulic oil with water glycol?: Water glycol lubrication performance is poor, high pressure, sealing components and cylinder block of friction, fever is very serious, so require sealing material to withstand high temperature, usually use fluorine rubber material. Polyurethane is not high temperature, more than 80 degrees when the deformation under pressure, the intensity is low, simply can not use.
