Rotary joint test

At present, China's rotary joint manufacturers are mixed and do not form a unified standard, so we always hear a word: how to buy a rotary joint there yesterday, it will not take long to leak, or I just bought it and put it to use There is a leakage problem, which can only explain one reason. In the process of shipment and production, QC inspections have not passed. In order to ensure the good use of customers without worrying about these basic problems, Hindley Corporation has set a high level of self-help. Standard and high-quality testing methods, first of all, let's discuss why leakage occurs. The first-use material does not conform to the standard, the second seal does not meet the dimensional requirements, the third design is backward, the fourth does not have the inspection standard and inspection method, and the so-called material does not conform to the standard because it depends on the rotating seal, and the selected The seals are based on the design structure, so any error in one of the links will lead to leakage of the rotary joints, and the service life will be short. From the raw materials entering the factory to the finished products, Hindley has passed strict inspections. Components, the content of each element, in accordance with the national steel standard comparison, the design part through the designer to the design engineer and then to the design director, layer approval, making a set of rotary joints, through the design department to provide drawings and requirements to The technical department and the technical department also use the design principles of the drawings and the related materials. During the distribution to the production and production process, each workpiece must achieve an accuracy of 0.01 mm. The purpose of this is to maintain good quality for the later assembly. Sealing, through a track test, the final inspection before shipment is very heavy With the latest electronic detection means, first through the hydraulic pump air pipe rotary joints, driven by the motor, the joint rotation as a whole, in the adoption of equipped with temperature sensors, speed sensors, pressure sensors, the data display records, each finished product test ten For group data, each group of data has a speed measurement time of two hours. Therefore, the test time of a single product is nearly one day. The average value of these ten groups of data is obtained, and the technical parameters of the rotary joint are obtained. This is simply the detection of the ventilating rotary joint. The overall test, while the gas-liquid rotary joint test, time, and stepping are more complex, will carry acid and alkaline liquids, and at the same time pass the test swivel, each joint outlet is affixed with a ph test paper, and the corresponding test ten Group data, if the rotary joint does not leak, then the corresponding outlet ph test paper will change to the corresponding color according to the outlet medium, and if the rotary joint leaks, the ph test paper attached to the outlet hole will have the color and the standard color. Difference, the average value of each set of data, and how to detect the internal seal? Hindley Corporation adopts imported seals. From the seals to the factory, we must first measure the overall balance of the seals. The testing device is a horizontal strategy instrument, measures its overall balance, and again measures its circularity and measures again. Gas wear resistance, through the rotating grinding machine, testing its grinding time and wear pressure, high temperature equipment to detect whether it is resistant to high temperature, acid and alkali infiltration detection of pH value, only through the detection of the seal Can be used, the internal use of imported high-precision bearings, after the bearing into the factory, first of all its material and fit analysis, the main use of photoelectric sensors with digital display, the bearing is assembled in place for analysis, and then using high-speed machine with The test sensor measures the bearing rotation speed, tests the temperature resistance of the bearing through a high-temperature instrument, and at the same time detects the degree of fit of the bearing on the rotary joint. The instrument used is a photoelectric magnifier. Only the bearings that meet the standard can be used, and the detection means are subtle to every one. Screw, what type of connector fits what type of screw, only the quality Only by high-level to each component can we win the customer's confidence and good reputation. Only through layer-by-layer inspection and review can we improve the quality to a certain level, and then we can use the products in every corner of the world in order to allow customers to use it with confidence. The purpose of Hindley's company is "The greatest confidence of customers is that
