Pump industry suppliers - The types of titanium centrifugal pump mechanical seal

titanium centrifugal pump mechanical seal type:

1, end face can be divided into: single, double mechanical seal.

single mechanical seal: titanium centrifugal pump consists of a pair of the seals of the mechanical seal. Simple structure, easy manufacture, installation, commonly used in the medium itself good lubricity and allow trace leak condition.

titanium centrifugal pump double mechanical seal: there are two of the seals of the mechanical seal. When the medium itself poor lubricity, toxic, flammable, explosive, easy to play, and have strict request for leakage. Two introduced between higher than that of medium pressure seal cooling liquid, sealing and cooling.

2, according to decorate a form of spring: spring built-in external type mechanical seal mechanical seal and spring.

spring built-in titanium centrifugal pump mechanical seal: spring for the medium in contact with the media. Susceptibility to corrosion, easy to be medium sundry jam, if the spring with the axis of rotation, should not be used in high viscosity medium.

titanium spring external type centrifugal pump mechanical seal: spring is not as far as the medium is not in contact with the media. Used in high corrosion, the equipment of medium to high viscosity and crystallization.

3, Ann balance way points: balanced and unbalanced type mechanical seal.

titanium centrifugal pump balance type mechanical seal: make medium effect on the seal face pressure unloading. It can reduce the friction and wear on the face, reduce the friction heat, carrying capacity is big, but the structure is complex, generally need to be in the shaft and shaft sleeve on a step, the cost is higher.

titanium centrifugal pump the balance type mechanical seal: cannot make medium pressure unloading on the seals.

4, according to the seal face contact points: contact and non-contact mechanical seal.

titanium centrifugal pump contacting mechanical seal, seal face in the border or half fluid lubrication state. Simple structure, less leakage, but wear, power, calorific value is bigger, use limited by certain in high speed under high pressure.

titanium centrifugal pump non-contact mechanical seal, seal face in full liquid lubrication state. Calorific value, low consumption, normal not wear at work, can work in harsh conditions such as high speed, but leakage is larger.

5, according to the form of elastic element points: rotary mechanical seal and stationary type mechanical seal.

titanium centrifugal pump rotary mechanical seal: elastic element with the axis of spin pack. , which is used widely because of spin pack as vulnerable to the role of centrifugal force on the spring will affect the seals of the pressure. Not suitable for high speed.

titanium stationary type centrifugal water pump mechanical seal: elastic element with the axis rotation. Suitable for high speed. Suitable for high speed.
