Negative pressure pump "," Positive pressure pump "mainly from the main functions and uses to distinguish between people." Negative pressure pump "is mainly used in the vacuum (negative pressure) requirements of the occasion, such as: extraction, gas analysis, gas Circulation, gas sampling, vacuum adsorption, indirect water absorption, etc .; and "positive pressure pump" is mainly used for pumps need as a driving force for gas transfer, closed container pressurization, inflatable cheer, indirect pressure water, Research, environmental protection, equipment, control and so on. "Negative pressure pump" exhaust end is also positive pressure, but only slightly positive pressure, than the "positive pressure pump" output pressure is much smaller, such as micro-vacuum pump VM, VAA, PC and other series is "negative pressure pump "," Aspirator ", and their discharge end pressure is often only a few kPa;" positive pressure pump "suction end is also a slight negative pressure in order to complete the pumping effect. Gas booster pump series for the two booster pump, you can very low pressure gas to high pressure, driving pressure ≤ 7bar, gas inlet pressure range of 0.5-10bar, the maximum can be increased to 90Mpa. The series of pumps and N series of commutation exactly the same way, the entire pump all made of aluminum and stainless steel. In the air-driven part of the pump, this series requires lubrication of the gas, so that seals and other internal parts to be lubricated, the series pump drive piston diameter of 160mm. Gas booster pump series for the single-stage booster pump, in order to achieve the required The input air pressure at the pressure gas inlet requires some degree of precompression and the pre-boost pressure will vary depending on the maximum pressure of the gas booster pump image. The maximum pressure to 80Mpa. Gas booster pump H series uses single gas-controlled unbalanced gas distribution valve to achieve the pump reciprocating motion, all made of aluminum alloy and stainless steel. All seals are imported quality products, the maximum design-driven pressure is 10bar, in order to ensure the life of the pump drive pressure <8bar. This series of pump piston diameter of 160mm, a single-acting pump, all single-acting pump with exhaust cooling. Gas booster pump N series is a two-stage booster pump, which can increase very low pressure gas to very high pressure. The driving pressure is less than or equal to 7bar. The pressure range of gas inlet is 0.5-10bar and the maximum can be increased to 90Mpa. The series of pumps and B series of commutation in exactly the same way, compared with the B-type flow rate doubled Booster pump mechanical installation Tap water booster pump must be installed according to the "installation" display in the horizontal or vertical installation, the direction of flow should be consistent with the direction of the arrow on the pump body, and installed as far as possible from the water level lowest position. For ease of use and service, a valve should be installed on the pump inlet line. When the suction level is lower than the pump impeller or the pump shaft around the pump when the check valve should be installed, the outlet connected to a tee for water diversion, in the first use should be filled with water pump and Tighten the plug. Pipeline connections should be tight, especially the inlet pipe can not leak otherwise it will reduce the pump lift or pumping on the water. Pump cavity is not water, do not even a long time even turn, so as not to damage the seal. The motor coil is equipped with a safety protector. When the pump fails or does not pump water, the motor can automatically open when the temperature rises more than the specified value. After the motor temperature rises, the motor can resume operation automatically. The booster pump motor is a capacitor-operated motor. When the pump is shipped, the direction of rotation has been adjusted. If it is necessary to replace the capacitor or re-connect the motor, please press the arrow mark on the pump body. To ensure safe operation, you must use a three-pin safety socket with a grounding wire. Pump leakage found immediately shut down to prevent internal leakage, if the connection with the motor leakage should be replaced mechanical seal. Check if the power is on. Use the power supply voltage is consistent with the working voltage of the pump. As above a, b normal; please remove the pump, open the pump cover, remove the foreign body in the pump, and then install the pump cover, tighten up to normal. When the pump can not pump water, the pump is installed on the water pipe. If the water level is below the plane (horizontal installation) or the center line (vertical installation) of the pump impeller, the power should be turned off at this time. When the tap water level rises more than Impeller plane or centerline, then turn on the power, so as not to damage the mechanical parts (automatic type without electricity). When the pump is used to pump well water, please check if the water inlet pipe leaks; if there is not enough water in the pump chamber, it should be filled with water; if the suction stroke is too high, adjust it properly. Check the import and export pipe diameter is too small or blocked. Automatic use of a period of time, may appear automatic failure phenomenon, mainly in the water pipe rust and other metal products from long-term precipitation, turn off the power after removing the switch, unscrew the screw above, remove the plastic sheet to be cleaned, and then , According to the original reset, debugging normal, you can re-use.
