"Negative pressure pump", "positive pressure pump" mainly from the function and the main purpose to make a human difference. "Negative pressure pump" is mainly used in vacuum (negative pressure) requirements of the occasion, such as: gas extraction, gas analysis, gas circulation, gas sampling, vacuum adsorption, indirect water absorption; and "positive pressure pump" is mainly used for the needs Pump as a motive force, the gas transfer, the pressure on the closed container, inflatable cheer, indirect pressure of water, both commonly used in medical, scientific 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 picture. 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

Expansion joints reduce vibration, dampen sound, and accommodate movement in piping systems.
There are two primary types of expansion joints-metal and non-metallic or elastomeric. Metal expansion joints are constructed in a bellows configuration from thin-gauge material designed to absorb mechanical and thermal movement. Elastomeric expansion joints, by contrast, are fabricated from natural or synthetic rubber and fabric. Consisting of an inner elastomeric tube fused to a metal-reinforced fabric body and an elastomeric cover, these types of expansion joints accommodate greater pipe movement and provide more abrasion resistance than metal joints.
