Description
Technical field
The present invention discloses a kind of auxiliary products of condenser/evaporator, a kind of four kinds of functions (four unification) novel double-flow water-cooled handpiece Water Chilling Units shell-and-tube cooler/evaporimeter end socket bobbin carriage that integrates particularly, particularly be used in the water-cooled handpiece Water Chilling Units shell-and-tube cooler of double-flow, also be applicable to simultaneously the full liquid evaporimeter of shell-and-tube of its double-flow, and cooling water is walked tube side and temperature is no more than 80 ℃ double-flow water cooling tube shell heat exchanger.
Background technology
Existing cooling water water-cooled handpiece Water Chilling Units condenser glueballs automatic on-line cleaning device has following three classes, one class is an independently purging system device, couple together by pipeline with the condenser water inlet pipe and water outlet pipe, service robot sends glueballs the water inlet pipe of cooling water, glueballs flows into condenser with cooling water, clean and flow out from cooling water outlet after complete, enter and catch the ball device, enter in the service robot again.There is following drawback in this type of cleaning device: 1, need on-the-spot installation, workload is large, and can't dispatch from the factory with handpiece Water Chilling Units is supporting; 2, owing to require serve speed fast, so service power power configuration is larger, enter the current of water pump, air compressor machine or the larger pressure reduction of needs.Another kind of is that import and export at condenser arranges the four-way reversing arrangement, and the in-built cleaning element of condenser heat-exchange pipes to cleaning element is being moved reciprocatingly, cleans the heat exchanger tube inwall by the four-way change of current.Please see Chinese invention patent: publication number CN104151297A.This type of by the change of current to automatic flushing device have two drawbacks: 1, high-temperature water enters condenser during commutation, handpiece Water Chilling Units condenser inner refrigerant condensation temperature instantaneous variation is larger, the fluctuation of handpiece Water Chilling Units moment efficient is larger, operation brings greater impact to handpiece Water Chilling Units, causes the side effects such as handpiece Water Chilling Units surge when serious; 2, owing to the distribution reason of water flow field at the condenser card, the every flow velocity difference that heat exchanger tube is interior, so operation a period of time, the part cleaning element can't be made reciprocal washing motion, blocks in barrier element.Last class is a kind of front-end end enclosure channel box of shell and tube condenser of water-cooling water chilling unit with rubber ball online cleaning function, please referring to Chinese invention patent: publication number CN101691980A.There are following two drawbacks in this kind equipment: 1, only can implement rubber ball online cleaning function and can't satisfy handpiece Water Chilling Units Chemical treatment demand; 2, can't filter the impurity foreign matter that contains in the handpiece Water Chilling Units water inlet, service life of equipment is given a discount; 3, do not contain remote data monitoring transfer function, equipment vendor and applying unit need to arrive the scene and can receive and recognize equipment operation condition, be not easy to equipment about and the corrective maintenance maintenance; 4, can't observe online the transmitting-receiving situation of glueballs by visor; 5, need setting independently to add ball and put the ball device, need discharge large water gaging etc. when putting ball.
Summary of the invention
Need on-the-spot the installation for the above-mentioned of the prior art split type cleaning device of mentioning, and be equipped with high-power ball serving device, and the side effect that the four-way change of current causes to device, the invention provides a kind of compact conformation simple and reliable integrate the four kinds of novel double-flow water-cooled of function handpiece Water Chilling Units shell-and-tube cooler/evaporimeter end socket bobbin carriages, address the above problem.
