The vacuum suction pump R300 is used in a variety of laboratories and is suitable for use with a variety of sand core filter bottles, Buchner funnels, various filter bottle sets, multi-filters and other products. If the vacuum pumping pump is inadvertently operated during use, it will easily cause the liquid to suck back into the pump body and damage the vacuum pump. The vacuum pumping pump R300 has already considered such problems in the design of gas. Therefore, the air inlet is equipped with a buffer cup and a filter element as standard. The filter element can effectively prevent water vapor, dust and impurities from being sucked into the pump, while the buffer cup can be very Good collection of sucked liquid. The customer must have a liquid suction, only need to take the buffer cup and pour out the filtrate, and then put it back after cleaning. In addition to the use of a buffer cup as standard with the vacuum pump R300 , there are several ways to prevent liquid from sucking up: 1. Buffer bottle: Install a buffer bottle between the vacuum filter bottle and the vacuum pump R300. The buffer bottle capacity is recommended to be above 1000ml. The two interfaces inside the buffer bottle should be distinguished by height, the interface connecting the filter bottles is lower, and the interface connecting the vacuum pump is higher. This design can avoid the problem of secondary suction. 2. Water-blocking filter: A water-blocking filter is arranged between the suction pump and the vacuum filter bottle connecting hose. The water-blocking filter is also called a vent filter. The air can pass through the filter, but the liquid cannot pass, and the liquid is poured. The sucked liquid will be absorbed by the internal filter element, and it is the only water-blocking component that can achieve 100% anti-backup. 3. Check valve: The FU-P1 vacuum filter bottle under the St. Stephen brand has an anti-waste check valve inside. When the liquid level inside the filter bottle rises close to the bottle mouth, the rising liquid level will push the back. The valve rises and closes the suction port, which can effectively avoid the liquid that should be forgotten to pour out the filter bottle and cause a large amount of liquid to be sucked into the suction pump. Solving the problem of sucking back allows the customer to use the instrument with peace of mind and avoid the trouble of returning to the factory for repair. Once the liquid is sucked into the pump, the customer is not likely to panic, and some emergency measures can be taken to reduce the loss. Mainly divided into two kinds of cases: if it is a small amount of liquid inhalation, stop working immediately, pull out the pump tube, let the vacuum pump pump air for 20 minutes, you can discharge the liquid by yourself; if a large amount of liquid is poured in, stop working immediately, turn off the vacuum pump Contact the manufacturer for repair and continue to use the motor which may cause further damage.
