Fixed tube heat exchanger consists of tube bundle, tube plate, shell, head, folded plate, etc. Tube bundle ends fixed in the tube plate, the tube can be expanded (the inner hole of the tube with mechanical expansion, so that the tube wall from the inward to outward extrusion and fixed in the tube plate) or welded to the tube plate. The tube bundle is placed within the tube shell, with headers and flanges fixed at both ends. In this way, one fluid flows from the inside of the tube and the other from the outside. The space between the two heads and the tube plate is used to distribute or collect the fluids inside the tube. The two fluids do not mix with each other, but only exchange heat through the tube wall.
Advantages: simple and compact structure, high pressure resistance, low cost and easy to clean the tube side.
Disadvantages: Risk of blockage when the tube is damaged or needs to be replaced.
When the difference between the wall temperature of the tube bundle and the shell or the coefficient of linear expansion of the material is large, a large thermal stress will be generated in the shell and the tube bundle. A flexible compensation ring (also called expansion joint) should be installed on the shell to reduce the thermal stress.

1. The reliability of the hydraulic system mainly depends on the cleanliness of the hydraulic system, in addition to the performance of the hydraulic components. The main factor affecting the cleanliness is that the rust layer of the steel pipe cannot be removed. To this end the company is equipped with a shot blasting machine and uses the only special process in the country to handle: internal surface blasting - pickling - rinsing - passivation - sealing - electrophoresis, tubing also needs to pass before Internal surface cleaning - blow drying - oil rust prevention and other processes to ensure the stability of the entire hydraulic system.
2. All hydraulic components undergo hydraulic bench inspection before purchase into storage to fully ensure that the hydraulic components meet the calibration performance requirements.
1.Our company has 1000,600,500,100 and other series tonnage hydraulic presses, which can meet the bending forming of all arm plates, only the middle two welds, and all use carbon dioxide protection welding, the length of the weld is more than 500mm Automatic welding is used, which not only has a small weld seam, but also has a beautiful appearance, low stress, and high strength.
2, all components in the welding are used fixtures, fixtures to ensure the production accuracy.
3. All components are tested by ultrasonic weld after welding, which has high safety.
4, all the plates are used underwater plasma CNC cutting machine, CNC wire cutting machine, cutting machine cutting, so the production of high precision.
Third, paint:
1. The company is the sole manufacturer of wrecker manufacturers in the country, which is equipped with an electrophoresis production line. All metal structural parts are degreased, cleaned, rust-proofed, cleaned, surface-modulated, phosphatized, and electrophoretically treated before being assembled. More than 800 hours of sex, strong rust resistance.
2. Our company owns the original paint booth imported from Italy. After the electrophoresis primer, the surface is sprayed with imported ici paint and then baked by the paint booth. The appearance is beautiful, the strength is high, and the anti-rust ability is extremely strong; The customer asked for spraying, the appearance is more personalized.
Fourth, the vehicle:
1. The entire vehicle production process is strictly inspected according to the standard after blanking, bending, welding, assembly, rig testing, assembly, commissioning, and general inspection. The uploading rack test is a unique process of our company. Completely guarantee quality requirements, so that customers can rest assured that use.
2. Press the "wrecker standards" in the requirements, the number of new products in the approval test the reliability of the test was set at 500, and the standard, the number of tests required for the company's 2,000, much higher than the "wrecker "Car standards" requirements, so as to ensure the performance requirements of the vehicle.
Content introduction: First, the hydraulic system: 1, the reliability of the hydraulic system in addition to the performance of the hydraulic components itself, mainly depends on the cleanliness of the hydraulic system, and the main factor affecting cleanliness is the rust layer of steel pipe can not be removed. To this end, the company is equipped with a shot blasting machine and uses the only special process in the country.
