But so far, pumps,
valves, hydraulic parts and other accessories needed by small thermal oil pumps are basically all dependent on imports. In addition, lift and shrink arm forklift, sliding steering loader, two busy small thermal oil pump market are also in the process of cultivation, will have greater development. Not only delivery time can not be guaranteed, at the same time, the price of the full set of hydraulic system purchased from abroad is generally not negotiable; In addition, pre-sale and after-sales service is not in place, which greatly restricts the development of domestic thermal oil pump enterprises. At present, most of the hydraulic parts needed for the small thermal oil pump such as small wheel loader, excavator loader (busy at both ends), sliding steering loader, telescopic arm fork loading and small tonnage forklift isostatic transmission are dependent on imports.
A: select a breakthrough: in view of the overall development level of thermal oil circulation pump and the current specific situation, Ma Chuanwei suggested that small digging and other small thermal oil pump accessories as a breakthrough, to contribute to the overall development of China's thermal oil pump accessories industry. There are also problems with heat treatment. This year, China's thermal oil pump enterprises, there are foreign fittings enterprises paid for a year and a half, still can not take the goods, such as Hefei Zhenyu; Everything is installed, just waiting for a valve, but The Japanese enterprise can not supply, such as yuchai machinery; Last year's Xu digging machinery, at the beginning of the year to Japanese enterprises to order, the result was still not to the end of the goods, resulting in zero output of excavators. Product reliability is related to management, process equipment and process route. It is reliable to produce ten or eight pieces in small batches, but not in large quantities. Internationally, most of the loaders with less than 3.0 tonnage in advanced countries have realized hydrostatic transmission, while almost all of the loaders with an annual output of more than 100,000 units in China are hydraulic transmission. For example, the thermal conductivity oil pump products produced by foreign enterprises are generally the first failure in 1000 hours, while our products are only 400 and 500 hours. If the reliability problem is not solved, users will not buy it, even if it is sold at a lower price. In addition to the key technology constraints, Ma Chuanwei believes that another important aspect of the gap between Chinese thermal oil pump fittings and foreign products lies in their reliability. Domestic thermal oil pump enterprises are generally not large, to the steel mill for special purchase, others ignore. There are also gaps in technology and equipment with foreign countries. There are flexible production lines in foreign countries, and each procedure is strictly controlled.
Two: accessories constraints: at present, China's thermal oil pump, especially small thermal oil pump, has broad market prospects, small digging market is very clear, it is expected to the end of the "11th Five-Year plan", small digging market demand may reach 50,000 units. In order to realize the comprehensive development of small heat conduction oil pump accessories including small digging, the realization of its hydrostatic transmission is an important link. At present, shandong Longtai is the only private enterprise that can produce hydrostatic drive accessories in China. This private enterprise can produce hydrostatic drive loaders of less than 3.0 tons, but it is only the beginning of production, which is not mature, and the production is still complete machine. In the Annual meeting of The Chinese thermal oil pump accessories industry, Ma Chuanwei and the relevant person in charge of the accessories branch suggested that manufacturers will pay attention to the other small thermal oil pump accessories from only small digging guide to take into account other small thermal oil pump accessories, to small digging accessories as a breakthrough, drive the comprehensive development of other small thermal oil pump accessories.
At present, China's thermal oil pump industry is in a high stage of operation, thermal oil pump enterprises show a thriving situation, however, the accessories are like a rope around the neck of the enterprise, so that it can not sleep easily. This bureau will play a more and more important role in China's thermal oil pump production enterprises. The components produced in this way are not reliable, which leads to the failure to improve the quality of the mainframe. Foreign accessory enterprises, first to meet the needs of their domestic enterprises, second to meet the needs of foreign enterprises in China, and third to consider the needs of our local enterprises. Generally speaking, the main factors affecting the reliability of Chinese accessories are the quality of raw materials, especially steel. Recently visited the China Thermal oil pump Industry Association thermal oil pump fittings branch secretary Li Hongwei, asked him to talk about China RY thermal oil pump fittings industry problems and analyze the development prospects.
