Hydraulic fittings material

Hydraulic fittings material:
Stainless steel is a versatile stainless steel material, anti-rust performance than the 200 series stainless steel stronger. Also relatively good high temperature, the general temperature limit is less than 650 ℃. 304 stainless steel with excellent corrosion resistance between energy and good resistance to intergranular corrosion. On the oxidizing acid, obtained in the experiment: ≤65% nitric acid concentration below the boiling temperature of 304 stainless steel with strong corrosion resistance. Most of the alkali solution and organic acids and inorganic acids also have good corrosion resistance.

swivel fitting's precautions

Users in swivel fitting's store and use should note the following:
(1)to prevent damage and intense vibration. because the sealing element within the female swivel fitting use of non-metallic materials, by the impact is likely to cause the seal
parts damage, while, when the damage mounted externally threaded connection lead to the installation
(2)should be kept inside the drum and pipe cleaning, should pay particular attention to the new equipment, if necessary, is the need to add filters to avoid foreign body metric adapters cause abnormal wear.
(3) When the rotary joint leak was found, the cause of the shutdown should promptly check the sink drain, the sick do not work, in order to avoid parts of isobutyl often damaged. Because the machine is not used for a long time can lead to internal scaling and rotating joint from rust, and note that cards such as re-use die or drip the occurrence situation.
(4) with oiling device periodically oiling, swivel fitting through the heating medium medium should gradually warming up, avoid abrupt changes in temperature.

Installation of the swivel fittings

Installation of the swivel fittings
Swivel fittings is installed correctly, not only the performance of the swivel fittings into full play, at the same time prolong life, improve work efficiency,
Non-standard installation often use swivel fittings seal can not play the role, while the internal parts wear out quickly scrapped. So Mastering Regular Correct swivel fittings installation method is that each user must have.
(1) swivel fittings must be adjusted with the device at low speeds when connected, the device is adjusted to the rotor rotation of the swivel orfs fittings Heart maintaining concentricity, then the tight positioning.
(2) the housing swivel fittings are generally required to stop rotation (large size of the connector shell guide support required), this stop mechanism must be flexible nature, rather than rigid, in addition to limiting the rotation, the degree of freedom in other directions must be guaranteed, it is correct to use the right swivel fittings an important factor.
(3) generally metal hose connected to the rotary joint, the choice of length of the metal hose must be taken into account so that (2) in the above freedom is guaranteed. Some users implement a rotation stopper (2) in the taut metal hose with a method, which is far from the norm.

Note the following parameters when the rotary joint design

Note the following parameters when the rotary joint design
① Structures equipment and bsp swivel fittings and related dimensions.
② equipment transfers and direction
③ Media Name and temperature, pressure
④ provide an interface in the form of swivel fittings and metal hoses connected and dimensions

Selection of the rotary joint

(1) First, the structure of the connected device and use the female swivel fitting to determine the type: if the structure of the device determines the input media and the output medium for device along one side, you must choose the road type rotary joint complex. If the decision by the structure of the device input and output media and output medium on each side of the device to achieve, you must choose a single channel swivel fittings
(2) If requested to simultaneously deliver a variety of media or the media output to multiple locations should be considered in the choice of multi-channel type rotary joint.
(3) According to the desired input and output medium flow path selection swivel fittings
(5) Determine buried, flanged or threaded connections and inner tube rotary or fixed connection, but bear in mind in the form of equipment and rotary joint connecting structure: If you select swivel fittings threaded connections, must be clear of the rotational orientation of the device .(4) Select the rotary joint performance with the appropriate speed according to media pressure and equipment.
(6) Note that their relevant parameters selection.

Double-loop swivel fittings

Such swivel fittings can be divided into fixed double loop and double loop rotary swivel fittings. Sealing surface and seals made of special material, abrasion resistance, long life, corrosion resistance, not leak. Internal seal wear condition by visual appearance of the product that can prevent mechanical stop or mechanical damage, came preventive effect and reduce losses. Which has a separate line, can be used to choose different work needs to maximize the benefits. Housing and the shaft consists of precision bearings, so that rotation of the swivel flexible, lightweight, low friction, the liquid medium may include water, oil, air, etc., the use of industry wide. The replacement of worn seals easy maintenance without re-purchase of new products, cost savings.

Single-loop swivel fittings

Single-loop swivel fittings to follow the work of the case to select the connection method. Transmission medium inlet to follow the work of the freedom to choose sides or rear to enter. Sealing surface and seals made of special material, abrasion resistance, long life, corrosion resistance, not leak. There are two internal rotary joint precision bearings, smooth operation, durable, strong and flexible, friction coefficient is small, it can be high speed. The condition can be worn inside the visual appearance of the product that can prevent mechanical stop or mechanical damage to achieve preventive effect and reduce losses. The replacement of seal metric fitting easy maintenance without re-purchase of new products, cost savings. Circuit series rotary joint: to meet domestic demand in various industries, fluid medium water (water), vapor (steam), oil (oil), air (Air), vacuum (vacuum) cutting fluid (coolant), toluene and other chemical agents.

swivel fittings effect on the whole machine equipment

swivel fittings are non-functional parts of the machine, but its effect on the whole machine equipment, and even affect the entire plant are great. Especially with the rapid development of various industries, swivel fittings will be more widely used. swivel fittings is the role of the rotating fluid medium pipelines, reciprocating motion or swing (turn) the angle of movement of a device is connected, both to ensure the continuous transfer fluid to operate equipment,pipe fittings, but also to prevent collusion between the fluid medium, leakage and external debris into the working medium.
