Hydraulic Manual Hand Pump For Double Packer Hole Sealing

Hydraulic Manual Hand pump for packer, manual pump for packer inflation

Working Principles:

The hole packer is connected to the grout injection pump, so that the hole sealing materials can enter the front and rear hole packer. Due to the effect of the check valve, grout can flow through the front and rear hole packers, and driven by the pressure (4Mpa) at the explosion relief valve, the expansion runner hose at both ends of the hole packer expands and fix the hole packer securely to the hole walls by the frictional force produced by the rubber materials. Then the hole packer can seal both ends of the hole. The explosion relief valve ruptures, so that grout flows through the explosion relief valve and fills the space between two hole packers, to realize hole sealing under pressure (1-3Mpa). A gas drainage hose is then connected to the gas drainage pipeline to drain the gas.
