Gasket spacer

Grips, buttons, bumpers, seals, feet, gaskets, spacers for electrical machines. .. 

Two membranes and two gasket spacers form a single cell pair. Holes in the gasket spacers are aligned with holes in the membrane sheet to form the manifold... 

FIGURE 4.22 A schematic diagram of a sealed liquid cell. The gasket/spacer seals the liquid between the infrared transparent windows and holds the windows a fixed distance apart, giving a known pathlength. 

Electrochemical cells are assembled in the glove-box. The cell is a 2320-type coin cell (23 mm OD and 2.0 mm thickness) as schematically shown in Fig. 5. The cell includes the electrolyte, the cell cap and can which are stainless steel, a polypropylene gasket used to seal the cell, the two electrodes, the separator between the electrodes, as well as a stainless spacer and a mild steel disc spring which are used to increase the pressure on the electrodes. Once the cell is assembled in the right order, the cell is sealed by a pressure crimper inside the glove-box.

All three cells utilize neoprene gaskets to cushion the fragile salt crystals from the metal frame. In the case of the sealed and sealed demountable cells, the top neoprene gasket and window have holes drilled in them to coincide with the inlet and outlet ports to facilitate filling the space, created by the spacer,...

The spacer material does not need to be PVC, I used it because it was transparent. You could use rubber gasket material. Just make sure it s soft so that the stack doesn t leak. Transparent silicone rubber would probably be better than PVC, but it s also a lot more expensive. Just make sure you go with 1/8" or 3mm spacing. 

The spacers initially used to separate the electrodes were epoxy resin-gasketed glass cloth about 2 mils thick. The spacers were successively replaced by filter paper disks fitted to polyethylene rings 0.02 inch thick and then by Dacron felt Vie inch thick. With the latter spacers, the gasketing material enclosing the periphery of the l1/4-inch-diameter Dacron separator was polyethylene rings 0.10 inch thick.

The membranes in an electrodialysis cell are separated by spacer gaskets as indicated in Figure 5.3, which shows schematically the design of a so-called sheet flow electrodialysis stack. The spacer gasket consists of a screen that supports the membranes and controls the flow distribution in the cell and a gasket that seals the cell to the outside and also contains the manifolds to distribute the process fluids in... 

Figure 5.3 Exploded view of a sheet-flow-type electrodialysis stack arrangement indicating the individual cells and the spacer gaskets containing the manifold for the distribution of the different flow streams.

The sample is poured into a cavity in a single or double sector centerpiece, made of an aluminum alloy or an epoxy resin material [Fig. 13.9(h)]. The centerpiece is fitted with transparent windows made of quartz, or sapphire if high g forces are required. A cell housing (with related parts including spacers, gaskets and screw rings) that holds the cell assembly fits into the ultracentrifuge rotor. A simplified... 

Plate modules are mainly used for dehydration applications, with stainless steel used as construction material for support plates for the membranes and for spacers. Gaskets are normally graphite based and...

Usually, die supply ducts for the various solutions are formed by matching holes in the spacer frames, membranes, gaskets, and end frames. Each spacer frame is provided with solution channels (at point E in Erg. 21.2-3) that connect the solution-supply ducts with the solution compartments- Hie spacer frames have mesh spacers or other devices in the compartment spaces to support die ion-exchange membranes and se to prevent collapse whea these is a differential pressure between two compartments. These mesh spacers are selected or designed to aid in lateral mixing, which decreases die thickness of boundaiy layers.
