Abstract
The invention discloses a pump pipe production and machining process, which comprises the following steps of: 1, wear-resistant ring pretreatment: carrying out pretreatment such as quenching and polishing on a wear-resistant ring for later use; 2, flange welding: welding a flange and a pump pipe body together; 3, pipe body quenching: carrying out quenching treatment on the pump pipe body welded with the flange in the step 2; 4, wear-resistant ring installation: installing the wear-resistant ring treated for later use in the step 1 into the pump pipe body provided with the flange and subjected to quenching treatment in the step 3; and 5, anti-corrosion layer coating: spraying an anti-corrosion layer on the periphery of the pump pipe body provided with the wear-resistant ring in the step 4. After many experiments, a pump pipe prepared through carrying out quenching 11 minutes under the quenching conditions that the oscillation frequency is 500 Hz and the voltage is 520V is the highest in mechanical strength and thorough in quenching.
Description
Technical field
The present invention relates to the production and processing field, specifically a kind of pump line production and processing technology.
Background technology
In building field, often can use concrete, carry these concrete, except a small amount of barreled etc., in heavy construction, often use pump truck, pump truck claims again concrete mixer, the machinery that utilizes pressure that concrete is carried continuously along pipeline.Formed by the pump housing and carrier pipe.Be divided into piston type, squash type, hydraulic diaphragm formula by version.The pump housing is contained on the automobile chassis, remilitarizes scalable or tortuous boom, just forms pump truck.
Important component part on the pump truck is pump line, and the abbreviation in concrete delivery pump pipe road is because concrete is called for short concrete (t ó ng), so often be called the concrete pump line.Be readily appreciated that, pump line is a kind of novel architectural engineering accessory product that occurs simultaneously along with the appearance of concrete pump, its appearance has improved the efficient of construction greatly, fast concrete conveyance is arrived the place that needs cast need to change into operating type artificial or one barrel of bucket of crane or a pipeful of bucket in the past, efficiency of construction has been improved nearly a hundred times.Pump line generally is divided into 125 and 150 two kind, and these two kinds respectively have high pressure and low pressure minute.The low pressure model of 125 type pump lines is that external diameter is the pipeline of Φ 133, and high pressure is that external diameter is the pipeline of Φ 140; The low pressure model of the pump line of 150 types is that external diameter is the pipeline of Φ 159, and high pressure is that external diameter is the pipeline of Φ 168.The tube head of pump line is the pipe joint through special processing, is connected with body by welding, and the connection of every pipeline then is to connect by the pipe clamp that precision casting technology processes.
In order to increase the mechanical strength of pump line, tend to pump line is carried out Quenching Treatment.At present each step of Quenching Treatment generally is rule of thumb or conventional processing, mechanical strength after the quenching can have very large difference along with the physical condition difference in each step in quenching, in addition, wear-resisting ring in the pump line generally all is to pass through first Quenching Treatment, when pump line is processed, wear-resisting ring is easy to the annealing phenomenon occurs in secondary quenching, thereby reduces mechanical strength, increases potential safety hazard.
Summary of the invention
The present invention is above technical problem just, provides the stable and wear-resisting ring can butt joint place of a kind of rear mechanical strength of quenching to carry out Qa pump line production and processing technology.
The present invention is achieved through the following technical solutions:
A kind of pump line production and processing technology comprises following a few step:
Step 1, wear-resisting ring preliminary treatment, with wear-resisting ring quench, stand-by after the preliminary treatment such as polishing;
Step 2, flange welding, with flange and pump line pipe welding together;
Step 3, body quench, and will carry out Quenching Treatment through the pump line body that is welded with flange that step 2 is processed;
Step 4, wear-resisting ring are installed, and will pack into through the pump line body that flange is installed after the quenching of step 3 processing through the stand-by wear-resisting ring that step 1 is processed;
Step 5, corrosion-resistant coating spraying will have been installed through step 4 the upper anticorrosive coat of the peripheral spraying of pump line body of wear-resisting ring.
Through test of many times, draw at last quenching condition adopts 500Hz under 520V voltage frequency of oscillation, the pump line mechanical strength after quenching through 11 minutes ground is the highest, and quenches thoroughly.
The specific embodiment
The present invention will be further described below in conjunction with the specific embodiment.
It is rear for subsequent use at first wear-resisting ring to be carried out in batches preliminary treatment (such as quenching, polishing, polishing etc.), then with flange welding on body, then will be welded with the electronic quenching that the body of flange adopts the frequency of oscillation of 500Hz to carry out 11 minutes under 520V voltage, after the body cooling, wear-resisting ring is installed in the flange on the pump line, carries out at last the spraying of corrosion-resistant coating.
Claims (2)
1. pump line production and processing technology comprises following a few step: step 1, wear-resisting ring preliminary treatment, with wear-resisting ring quench, stand-by after the preliminary treatment such as polishing; Step 2, flange welding, with flange and pump line pipe welding together; Step 3, body quench, and will carry out Quenching Treatment through the pump line body that is welded with flange that step 2 is processed; Step 4, wear-resisting ring are installed, and will pack into through the pump line body that flange is installed after the quenching of step 3 processing through the stand-by wear-resisting ring that step 1 is processed; Step 5, corrosion-resistant coating spraying will have been installed through step 4 the upper anticorrosive coat of the peripheral spraying of pump line body of wear-resisting ring.
2. described a kind of pump line production and processing technology according to claim 1 is characterized in that described quenching condition for adopt the frequency of oscillation of 500Hz under 520V voltage, and the cool time is 11 minutes.
