Showing spiral plate heat exchanger
|
|
Spiral plate heat exchanger spiral plate on the heat exchanger in 1930 by Sweden Rosenblad company research and development, our country in the 1950 s and was the first in the field of chemical industry, the introduction of application, 60 s batch generic, then by the ministry of machinery industry hefei general machinery research institute has been about the spiral plate heat exchanger design, fabrication, inspection and approval of the customer, the product quality inspection by also
The general management practices.
Spiral plate heat exchanger has good performance, from clean ability, small heat loss, heat transfer temperature difference is small, temperature stress, the compact structure, small advantages, its deficiency is affected by pressure
Ability and the diameter of the constraints and difficulty of maintenance.
The basic structure of the product has not detachable type and the demountable type two kinds, among them the demountable type in the long-term of the production practice and cooperate with the needs of the customers produced many structural changes,
Mainly in both ends and block on how to block passage is required to change, in order to adapt to the needs of the service, the clean.
Spiral plate heat exchanger in special need to roll trigger rolled on, in the process of production problems, most easily the most overlooked is used to separate, fixed between channel round steel plate, select material
Or former processes improper, in after welding can produce a lot crack, pores, cause large area leakage, and very difficult to repair.
Spiral plate heat exchanger in use should avoid the side channels of instantaneous generation big differential pressure and pressure fluctuations, such spiral plate cracking extremely easily, cause leakage. Not detachable type spiral
Plate heat exchanger is difficult to repair, many clients in equipment leakage occurred when the only scrap, actually to leak detection, repair is not difficult, only one end in cut part of the round steel, in the side
Word fill it with water, another side channel into the compressed air, through gaps in the distant observation bubbles can be spent to gradually find leakage point, which then dig holes of repair.
My company in design, manufacturing, maintenance spiral plate heat exchanger has accumulated a wealth of experience, hope to communicate with the customer, provide consulting service and offer the best price and high quality products.
