摘要： The invention relates to a gas separation pump and to a process for separating gas from a liquid when pumping the same. The pump (10) has a hollow shell, forming a separation part (26) with a large separation surface and a smoothly connected pump chamber (30), and a rotor with vanes (14) closely following the separation surface. The liquid-gas mixture flows along the large gas separation surface of the shell (12), whereby the gas essentially totally separates from the liquid and is discharged from the center of the pump chamber. The invention is particularly advantageous for air free recycling of paper machine backwater and for handling the products of flotation processes.

摘要： The invention relates to a pressurized screen for the screening of fibre suspensions, having a screen plate cylinder (16) surrounded by a housing (12) and containing a rotor (14). In said rotor there are dilution water pipes (22) directly connected to dilution water nozzles (20) discharging close to the screening surface of said screen plate cylinder (16) and rotating with said rotor (14). The invention also relates to a process for cleaning a fibre suspension in a pressurized screen, where the fibre suspension is diluted during the screening process with dilution water being fed directly from outside said housing (12) to said screening surface. The screen according to the invention is particularly favorable for use in the short circulation of a papermaking machine.
摘要翻译：本发明涉及一种用于筛选纤维悬浮液的加压筛，其具有由壳体（12）围绕并包含转子（14）的筛板圆筒（16）。在所述转子中，存在直接与稀释水喷嘴（20）连接的稀释水管（22），所述稀释水喷嘴靠近所述丝网印版滚筒（16）的筛网表面排放并与所述转子（14）一起旋转。本发明还涉及一种用于清洁加压筛中的纤维悬浮液的方法，其中纤维悬浮液在筛选过程中被稀释，稀释水直接从所述壳体（12）的外部进料到筛选表面。根据本发明的筛网特别适用于造纸机的短循环。

摘要： The invention relates to a centrifugal separator and a process for sorting a fibre suspension. Said centrifugal separator (10) comprises a rotor (24) coaxially inside a housing (12). The mantle of said rotor (24) has slots (26, 30) through which part of said suspension can be caused to pass from a space (25) inside of said rotor to a space (28) outside said rotor and from said space (28) outside said rotor to said space (25) inside said rotor. Said housing (12) comprises means (32) for introducing dilution water into the suspension. The separator according to the invention is particularly preferred for the use as a cleaner in the short circulation of a papermaking machine.

摘要： The invention relates to a process and an apparatus for recycling backwater in a papermaking machine. According to the invention backwater draining through a forming fabric is collected into several collecting means (51, 52, 53, 54) and pumped by separate pumps (20) in at least two and preferably numerous separate flows (81 to 85) directly as substantially air free separate flows to the fibre process (12, 30, 40) of the short circulation in order to implement a fast, air free and split recycling of backwater from said forming fabric to said fibre process.
