7。 Add enough plastic in the hopper. According to the requirements of different plastics, some raw materials are dried first. 8。 To cover the heat shield on the cylinder, so as to save electric energy and prolong the life of electric heating coil and contactor. 1。 Do not be greedy for convenience, wind shower room to cancel the role of the safety door. 2。 Pay attention to observe the temperature of the pressure oil. The oil temperature should not exceed the specified range. The ideal working temperature of hydraulic oil should be kept between 45-50 ℃, generally 35-60 ℃. 3。 Pay attention to adjust the travel switch to avoid collision when the machine moves. 1。 After the operation of the injection molding machine, the plastic in the barrel should be cleaned to prevent the oxidation of the remaining material or long-term thermal decomposition. 2。 The mold should be opened and the air shower room should make the elbow bar mechanism time in the locking state. 3。 The workshop must be equipped with lifting equipment. Great care should be taken when assembling and disassembling dies to ensure production safety. Five hazards of high temperature rise of injection molding machine! Thermal deformation of machinery.
Most of the others are to shorten the molding cycle and increase the output per unit time, so as to reduce the production cost and improve the competitiveness. Speed up, usually, to achieve the goal! Increase the motor and pump, speed up feeding! The motor and pump will be increased, or the feeding oil pressure motor will be smaller, multi loop system! The double loop or three loop design is adopted to synchronously carry out compound actions and increase mold waterways. However, there is no free lunch in the world. The improvement and transformation of machine performance can increase the production efficiency, but also increase the investment cost and operation cost. Therefore, the benefit evaluation before investment needs to be carefully measured, so as to produce the benefit of appropriate machine type. Injection molding machine is a kind of common plastic machinery. For the operators who use and purchase the injection molding machine, they should first understand what kind of performance a good injection molding machine has and what aspects need to be evaluated before they can choose a satisfactory injection molding machine. Power equipment: recovery of various power equipment and facilities, such as generators, transformers, power distribution cabinets, cables, shower room wires, tower and so on.
Scrap metal: industrial scrap iron, copper, titanium, tin, zinc, aluminum, nickel, aluminum alloy, stainless steel and other metals.?? Factory warehouse: recycle the overstocked products, semi-finished materials, electronic components, waste electronics, all kinds of plastics, hardware, cloth and other materials. Recovery of the whole plant equipment: recovery of closed factories, shower room door-to-door contact information, relocation of factories, building demolition, and equipped with a variety of large-scale demolition equipment. High altitude demolition of various difficult buildings, high price purchase of the whole plant equipment, as well as semi-finished products and waste materials.
We are a big waste collection station. The company has set up a recycling platform for waste materials and equipment (enterprises, electric power communication, office supplies and equipment, schools, hospitals, hotels and restaurants) all year round. We take enthusiasm and patience as the service tenet, and provide you with thoughtful recycling services at a fair and reasonable price. Guangming New District recycling air shower room door-to-door contact information, can greatly extend the service life of the equipment. Case description: Atlas Copco air compressor model is ga315w-8. 5. The recovered air shaft power is 315KW, the rotating speed is 1492r / min, and the air displacement is 864l / s. before cleaning, the head temperature of the compressor is about 97 ℃ and the oil temperature is about 86 ℃. When the temperature of the compressor head exceeds 100 ℃, the equipment alarms and the equipment stops when the temperature exceeds 110 ℃. Before cleaning, the operating temperature is close to the alarm temperature of the equipment, so it is urgent to clean the heat exchange system. After four hours of cleaning, the equipment was immediately operated. After cleaning, the temperature of the machine head was about 83 ℃ and the oil temperature was about 72 ℃. The temperature drop was obvious, which met the requirements of the enterprise. The control of air compressor noise pollution is a kind of sound that people don't need. It is a kind of public hazard, which has been raised to the agenda and needs to be solved. The noise pollution is various, but the classification of air compressor noise pollution is as follows.
