Positive displacement pump specialist ROBBINS & MYERS has introduced a non-intrusive pressure sensor that protects the pump under dry operating conditions and under high pressure conditions.
Designed to fit at the pump outlet, the RM pressure sensor is considered to be the most effective way to prevent the pump from interfering with operation, as opposed to other conventional 'presence / disappearance' detectors, stator temperature probes and other jamming devices.
At the same time, positive displacement pumps are considered as one of the most versatile pump designs with the following advantages: They handle abrasive fluids with minimal wear; accurately measure viscous liquids; and deliver extremely sensitive products with major limitations (Just like most pump products) are run dry. However, using RM pressure sensors is one of the most effective ways for users to protect their positive displacement pumps or other processing equipment during dry operating conditions or high / low pressure conditions.
The device consists of sensors, pressure switches and control box composed of three basic components. The sensor is mounted between two standard ANSI flanges to allow fluid flow to be unobstructed. Pressure detection throughout the piping system ensures that the enclosure, fixture, or jumper does not affect the pressure reading. A further feature is the presence of a liquid-filled manometer that visualizes the pressure throughout the pump system.
What is a windshield Wiper Transmission Linkage and where is it located?
The windshield wiper transmission is an integral component of your vehicle`s windshield wiper system. It is a mechanical device made up of multiple linkages that connect the Wiper Motor to the two wiper arms, transferring the power generated from the rotational movement of the motor when it is activated by the wiper controls into the sweeping back and forth motion of the windshield wiper arms which the blades that clean the windshield are attached to. The wiper transmission helps the wiper motor and arms work together without having to hit each other. The multiple sections of linkage are joined and held together by rivets, while bushings are mounted to the Wiper Linkage arms and act similarly to bearings. Together, they make it possible for the different sections of the wiper linkage assembly to rotate and pivot.
On most vehicles, the wiper linkage assembly is located under the cowl at the base of the windshield and hidden out of view. This protects the mechanism from being exposed to outside elements and allows for it to operate quietly when being used.
How do I know if my windshield wiper transmission needs to be replaced?
Windshield wiper transmissions are the most common failed parts of the wiper system and can require replacement for multiple reasons. A Windshield Wiper Linkage assembly will make an annoying clunking or squeaking sound when they wear out from prolonged use over time. Turning on frozen wiper blades without properly loosening them from an icy windshield during the cold winter season is a notorious and common cause of damage to wiper systems; this forces the wiper motor to put excess stress on the wiper linkages and arms. This stress can cause plastic connectors to break, pivot points to elongate, and knurled wiper studs to round off. Heavy snow and ice can also force the wiper motor to put excess stress on the linkages and wiper arms, as can large amounts of dirt, causing a similar outcome.
A broken or damaged windshield wiper linkage assembly can cause the wipers to not work or work incompletely, which can be quite hazardous for you and other drivers around you. Therefore, if your wiper transmission has failed, obtaining a replacement and installing it quickly is highly recommended.
