Welded pipe joints Features

Welded pipe joints Features: Welded pipe joints are fluid power and general use piping system necessary connections. In a hydraulic system, energy from the hydraulic oil through the hydraulic connections and that the tube hose system for delivery. If you put a hydraulic pump compared to a person's heart, then that is hydraulically connected vessels; modern industry requires increasingly higher hydraulic system operating pressure. Hydraulic adapters operation of the hydraulic system of hydraulic equipment requirements to withstand high voltage pulse, requires Welded pipe joints in the system must withstand higher peak pressure and vibration energy to guarantee the normal transport. Its failure will cause the pipeline leak, a serious cause of pipeline rupture. The first oil pipeline environmental laws and regulations is not allowed. More importantly, the modern large-scale mechanized production equipment shall continue to operate in order to ensure production efficiency, basically does not allow non-normal downtime; General hydraulic oil for Welded pipe joints is not corrosive, so the hydraulic system commonly used carbon steel welded pipe joints, drinking water or purified water should not be used to connect pipes carbon steel welded pipe joints.

Coupling coupler work to achieve

Coupling coupler is a use of liquid transfer torque to the continuously variable coupling in the new major power plants, the electric feed pump speed fluid couplings mostly used to adjust the pump speed to meet boiler load requirements, through to the pump variable speed Hydraulic pipe fittings  coupling regulate water flow and pressure to change to accommodate the unit start-stop, load changes, sliding pressure operation and grid FM peaking on the unit needs to improve unit operation variable condition the safety and reliability and economy, reduce throttling losses, while saving a lot of auxiliary power, to achieve the full adjustment automatic boiler feedwater

heat treatment process fluid coupling impeller

Fluid coupling impeller heat treatment process , characterized by the following steps:First step. Large diameter cast aluminum impeller hydraulic coupling before heat treatment to prepare a. Casting before the heat treatment must be clean, free of oil and non-corrosive substances , does not allow distortion, cracks, blisters , sand and other macro defects ; b. Heating with automatic temperature control with fan cycling solid melting furnace, temperature control at 350 ℃ or less , solid melting furnace should wind circle , to ensure unobstructed air path, so that a substantially uniform  Hydraulic ferrules heating conditions ;The second step. Solution treatment a. The large diameter cast aluminum impeller into the fluid coupling of solid melting below 350 ℃ solution treatment furnace and the furnace heating step , the heat treatment temperature of 530 ℃ -540 ℃, heat 4-9 hours ; b . Then 60 ~ 100 ℃ water cooling ;The third step. Large diameter cast aluminum impeller thermal hydraulic couplingaging treatment on large diameter cast aluminum impeller hydraulic coupling solution heat treatment after quenching stand at room temperature 96 hours -110 hours natural aging process ;The fourth step . Visual inspection : Casting allowed to have cracks , bubbles, corrosion and deformation obvious defects such as furnace into the same hardness test blocks and tensile test bars for mechanical performance test ;The fifth step . If you re- heat treatment of aluminum alloy castings large diameter cast aluminum impeller due to fluid coupling hardness, tensile strength , elongation unqualified, or deformed super- Chake repeated heat treatment, repeated re-submitted after the heat treatment , heat treatment is generally not more than two repeated , third after the heat treatment , is still unsatisfactory , casting scrap

hydraulic coupling failure analysis

Hydraulic coupling PTO shaft itself is cantilevered and radial thrust bearing , this support structure in the installation , the response bearing clearance and bevel gear gap to be adjusted to ensure correct meshing . Bearing wear , it must be timely adjustment and replacement. Otherwise, once the gap becomes large , so damage to the normal meshing bevel gears , causing additional load , resulting in deterioration of working conditions Hydraulic adapters bearings , gear teeth , the bend axis limp . If you belong to the working machine load sudden overload situation , you can install the output shaft torque limiter or safety couplings. Conveyor shaft bevel gear reducer and hydraulic coupler is fitted together , the structure is irrational, weight, and easy installation and removal process caused by the collision axis bending deformation ; factory fluid coupling is for only for static balance test , at high speed , because the added unbalanced loads and shaft vibration , deterioration of the operating state of the shaft .

Composition of fluid coupling

Main components : the pump wheel , turbine , turning housing , an input shaft , an output shaft and a spoon pipe . Normally, turning the shell and the pump wheel rim flange is bolted connection.Pump wheel and turbine called the working wheel, two in both blades, two to input , output shaft connection, there is a gap between them , the radial impeller and turbine are the same size as the cavity shape, so , together form the working oilHydraulic tube fittings chamber , the working oil from the pump into the inside wheel and rotates together with the following power machine , the oil in the centrifugal force , left to the outside of the pump wheel , the formation of high-speed turbine oil flow toward the opposite leaves , gradually slow down the flow of the turbine inner flow back into the pump wheel and the inside , forming a circulation of oil . The working fluid in the working chamber the absolute flow is a three-dimensional motion . Turn the pump wheel casing surrounds the turbine after connection , the energy stored in the working fluid into the pump wheel . Associated with the input shaft power machine ( such as motors ) , the output shaft and the driven machine associated ( such as pumps ) .
