Recirculated Rinses 1 and 2 can be designed to the same specifications. The body should reach rinse 1 within one minute of exiting the paint bath.? Rinse volumes of 50 GPM per 100 ft.2?(9.3M2) per minute have proven quite adequate. Spray nozzles should be adjusted to flood all surfaces of the body, both interior and exterior. Exterior surfaces are easily cleaned and require approximately 50% of the spray nozzles. Interior surfaces require flooding and direct spray to rinse those areas prone to runouts (see Figure 14). 第一道和第二道循環(huán)沖洗可設(shè)計(jì)成相同規(guī)格，每分鐘50GPM(加侖/分)/100平方英尺（9.3 M2）的沖洗量已相當(dāng)充分。噴嘴要調(diào)整到能噴到車身內(nèi)部和外部的所有表面。外表面很容易清理，直接噴洗那些朝下的表面（見圖14），這些沖洗要分四個(gè)區(qū)段并帶專用控制閥。
FlatJet nozzles made by Spraying Systems are recommended for exterior body rinsing and are helpful in controlling foam.? VeeJet nozzles are

acceptable but tend to atomize the permeate and cause foam.? Spray headers on 18 inch (45cm) centers and nozzles 18" from the body permit good rinsing and prevent spray pattern interaction, which can result in excessive foaming.? Floor headers must be equipped with individual control valves to prevent spraying into the sanitary pan. Nozzles for interior areas will vary depending upon requirements, but 30-40%, zero-degree nozzles are required for spraying across the body and for roof-rail rinsing.? Piping should be of stainless steel or a combination of stainless steel and PVC. 對(duì)外表面的沖洗建議使用有利于控制泡沫的Spraying Systems 生產(chǎn)的V型噴嘴。平嘴型噴嘴（VeeJet）也可以使用但容易使超濾液形成水物而引起泡沫。噴嘴集中在18英寸時(shí)（45cm）平管上沖洗效果好，且可避免噴射圖形相互干擾而導(dǎo)致嚴(yán)重起泡，建議設(shè)底板噴管以噴洗車身底板，底部噴管必須配單獨(dú)的控制閥以泳噴到接灰盤。內(nèi)表面噴嘴視各種要求而定，需要30-40%的零度噴嘴或扁管噴嘴作為車身橫截面噴洗及車頂裙沖洗用。輸送管道應(yīng)為不銹鋼或不銹鋼和PVC的化合物。 The systems with the least amount of foam are designed so that the car bodies are close to the floor and provide for a small "lake" below the rinse headers. These "lakes" constitute an integral part of the rinse reservoir and form the pump well when vertical pumps are used. The lakes should notextend beyond the zone risers. The reservoir should have a capacity of 3-to-4 times the pumped volume. The system design should include provision for agitation on the floor of the tank, and the agitation should be continuous, even during non-production periods.

系統(tǒng)要設(shè)計(jì)成使產(chǎn)生的泡沫減至最少，這樣車身靠近底部并在噴管下面提供一個(gè)“小池”這些“池”構(gòu)成了整個(gè)沖洗槽，在使用立式泵時(shí)也成為泵井，池外堰不能超過沖洗段的瀝水堰。槽子的容積應(yīng)為泵流量的3-4倍，系統(tǒng)設(shè)計(jì)包括提供槽底的攪拌，要求攪拌即使在不生產(chǎn)期間也要連續(xù)進(jìn)行。 Long shaft or vertical turbine pumps are in common use and should be employed for the recirculated rinses to eliminate the problems associated with seals? required for horizontal pumps. When vertical pumps are used, a foam baffle (note Figure 14.)? should be constructed to extend within 12 inches (30 cm.) of the bottom of the pump well to minimize foam migration outside the rinse. Rinse pressure should be 5-10 psi at the nozzle.? Circulation should be provided 24 hrs/day for agitation and filtration. 一般使用長(zhǎng)軸或立式泵，使用是用于循環(huán)沖洗可以消除使用臥式泵需要的密封問題，使用立式泵時(shí)要考慮一個(gè)一直伸到泵池的部12英寸（30cm ）之內(nèi)的泡沫隔板（見圖14），以盡量減少?zèng)_洗室外的泡沫形成，沖洗的壓力應(yīng)為5-10 psi（磅/平方英寸）。 Rinse tanks can be made of steel coated with Flakeline 600L or equivilent or of 305 or 304 stainless steel.? Rinses should be filtered to 25 microns (maximum) with the filter located between the pump and the spray headers.? The simplest, most nearly fail-safe rinses overflow by gravity from the ultrafiltrate storage tank to the rinse stages until the paint rich ultrafiltrate returns to the dip tank. Counterflowing should be maintained during non-production periods to reduce the paint solids in the rinses. 沖洗槽用涂上Flakeline 600L的鋼或等同的304 或305不銹鋼制成。沖洗液要經(jīng)裝在泵和噴管之間的25um（最大）的過濾器過濾?？贾亓某瑸V液儲(chǔ)槽自流到?jīng)_洗工序，在將含漆濃度高的超濾液返回到電泳槽是最簡(jiǎn)單的，也是最安全的沖洗溢流方式。在不生產(chǎn)期間仍要維持逆流以減少?zèng)_洗液中的涂料固體份。 The fresh ultrafiltrate rinse can be positioned immediately after the last header in the second recirculated rinse. Only 10-20 seconds of drain time is required before the application of fresh ultrafiltrate. 在第二次循環(huán)沖洗之后，可緊接著配置新鮮超濾液沖洗，在新鮮超濾液沖洗之前，要瀝水10-20秒。
