Washing scheme of mechanical seal manufacturer Washing of mechanical seal is an effective measure to control the temperature of mechanical seal and extend the service life of mechanical seal. The purpose of flushing is to take away heat, maintain and improve lubrication, prevent liquid film gasification, prevent impurity accumulation, prevent the formation of air bags, etc. According to the flushing form, it can be divided into internal flushing and external flushing, in which the internal flushing is carried out by using the transmission medium, while

Why should auxiliary facilities be used for kettle mechanical seal? In fluid machinery (such as pumps, compressors, agitators, centrifuges, etc.), the most demanding parts of mechanical seals for pumps under working conditions are mechanical seals. Bearing axial force like thrust bearing; Export the heat generated like a heat exchanger. It is difficult to achieve static sealing in high temperature, high pressure, corrosion prone and other parts, and the requirements are high

Common damage phenomenon of mechanical seal manufacturer's model and treatment method 1. Damage environment of mechanical seal model 1. Mechanical seal model equipment will present collision or deformation phenomenon of dynamic ring end face during use. 2. If the end face specific pressure of the mechanical seal type equipment is too large, the mechanical seal type parts for kettle will conflict and burn

Mechanical seal refers to a device composed of at least one pair of end faces perpendicular to the rotation axis, under the action of fluid pressure and the elastic force (or magnetic force) of the compensation organization, and with the cooperation of the auxiliary seal, to maintain sticking and relative sliding to prevent fluid leakage. Tell everyone about the leakage of mechanical seal

Technical requirements for kettle mechanical seal during installation Mechanical seal is a high precision mechanical part, which has a great impact on its correct device and operation and its service life. We generally follow the standards of the Ministry of Petrochemical Industry. The skill requirements for the pump and mechanical seal cooperation part of the mechanical seal device are as follows: 1. Shaft bending: Large not more than 0.05 mm; 2、

The effect conflict pairs of the fundamental components of the mechanical seal manufacturer shall ensure a tight fit and form a sealing surface to avoid medium leakage. This requires that the pump mechanical seal should have outstanding wear resistance; The moving ring can move axially to actively compensate for the wear of the sealing surface, making it fit the stationary ring well; Static ring has floating and buffering effect. 2) Elastic elements (tension spring, bellows, barrier, etc.)

The operating pressure of the seal should be the pressure of the sealing medium in the seal chamber. Since the medium pressure in the seal chamber and the mechanical seals are not equal to the operating pressure of the pump, and sometimes the operating pressure of the seal is higher, equal to or lower than the operating pressure of the pump, the operating pressure of the seal should be determined according to the detailed pump structure and conditions. For example,

Misuse of mechanical seal manufacturer's installation steps 1. The greater the spring compression, the better the sealing effect is. In fact, too much spring compression can lead to rapid wear and instant burning of friction pairs; Excessive compression makes the spring lose the ability to adjust the end face of the moving ring, leading to seal failure. 2. The tighter the dynamic ring seal diagram is, the better. In fact, too tight the dynamic ring seal is harmful and useless. First, intensify the seal ring and shaft sleeve
