The main components of high-temperature heat transfer oil pump and parts quality standards and overhaul High-temperature heat transfer oil pump is a more special form of positive displacement pump. It relies on a diaphragm to move back and forth to change the studio volume to inhale and discharge liquid. (A) high-temperature heat transfer oil pump mainly by the transmission part and the diaphragm head two major components Driven part is driven diaphragm driven back and forth, its transmission in the form of mechanical transmission, hydraulic transmission and pneumatic transmission. Po Taibang where the more widely used is hydraulic drive. The working part of the high-temperature heat-conducting oil pump is mainly composed of a crank connecting rod mechanism, a plunger, a hydraulic cylinder, a diaphragm, a pump body, a suction valve and a discharge valve, and the driving mechanism formed by the crank shaft, the connecting rod, Reciprocating piston pump is very similar. When the high-temperature heat-conducting oil pump is working, the crank and rod mechanism drives the plunger to reciprocate driven by the motor. The motion of the plunger is transmitted to the diaphragm through the working fluid (usually oil) in the cylinder so that the diaphragm moves back and forth. High-temperature heat transfer oil pump cylinder head part of the diaphragm will be mainly by the liquid to be separated from the working fluid, when the diaphragm moves to the side of the transmission mechanism, the pump cylinder negative pressure suction chamber and inhalation of liquid; when the diaphragm to the other side When the liquid is discharged. The liquid being delivered is separated from the working fluid by the diaphragm in the pump cylinder and comes in contact with only the pump inner side of the pump cylinder, the suction valve, the discharge valve and the diaphragm without contacting the plunger and the sealing device, Plunger and other important parts completely work in the oil medium, in good working condition. Diaphragm should have good flexibility, but also have good corrosion resistance, usually made of PTFE, rubber and other materials. Diaphragm on both sides of the mesh pot with the bottom of the parts is to prevent excessive local deformation of the membrane set, - commonly known as the diaphragm limiter. High-temperature heat-conducting oil pump seal performance is better, can easily achieve leak-free operation, can be used to transport acid, alkali, salt and other corrosive liquids and high viscosity liquid. (B) parts quality standards and overhaul Import and export valves Valve seat and the valve head should have a good anastomosis, anastomosis width of 0.25 ~ 2.00mm, and the above can not have rust, pitting and other defects. If it fails to meet the requirements, it can be combined with machining and centering percussion. Serious corrosion, the seat should be replaced. Diaphragm Diaphragm should be smooth, no scratches, flexibility to meet the requirements. 2.

6. Central Fume Extraction System
1) Cantilever type fume extraction system
Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the Suction Hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.

3) Room tupe fume extraction system
Room-type dust removal is suitable for the purification of fumes and smoke generated during the production of automated equipment, such as welding robots, welding machines, grinding, grinding and polishing of metal and plastic parts, drilling, thermal processing, cutting and crushing, stone processing, powder packaging, solid particles and various dusts and fumes produced by mixing and processing.
For working conditions such as robot automatic welding, circular seam and longitudinal seam welding, the smoke and dust purifier is installed with the robot workstation, so that the workstation has its own dust removal function. The fume and smoke are effectively collected through equipment components such as pipes and dust hoods. The room-type design prevents the volatilization and diffusion of smoke to keep the air in the workshop clean.
The working conditions with moderate welding workpieces and large amounts of dust and smoke are suitable for room-type treatment solutions. The room type centralized dust dedusting solution is divided into side suction and top suction method dust collecting ways. The appropriate solution can be designed according to the site conditions and treatment goals.
4) Blow suction type fume extraction system
Blow-suction type dust removal solution is a ventilation air flow composed of blown air and inhaled air flow. Therefore, it is a dust removal method that can effectively control the spread of pollution sources. This dust removal method is installing exhaust inlets on two-span center column or single-span side column (wall) and air outlets on the opposite wall column to form a circulating air flow to drive the smoke and dust into the purification machine, consequently performing overall dust removal and purification in the workshop. This system occupies a small area and has obvious purification effect, which is suitable for the purification of smoke and smoke in more complex production workshops.
