Claims

[Scope of utility model registration request]

(1) A diaphragm defines a pump chamber and a pressure displacement chamber to prevent gas from remaining in the pump chamber□
The reciprocating pump has a volumetric structure capable of increasing the internal flow velocity, and is connected to a suction pipe and a discharge pipe through a through hole, and a plunger is inserted into the pressure displacement chamber. A check valve is installed in a part of the discharge line connected to the pipe, a part of the discharge line leading to this check valve is branched off, and this branch line is opened for a fixed period of time when the reciprocating pump is restarted. 1. A reciprocating pump device, characterized in that it is connected in communication with a evacuable part that communicates with a handling liquid supply system through an automatically operated on-off valve.

(2) Utility Model Registration Scope of Claims In the reciprocating pump device according to claim 1, a part of the through hole communicating with the discharge pipe of the pump chamber is branched and connected to a gas vent pipe, so that the gas A reciprocating pump device, wherein a vent pipe is provided with a gas vent valve that momentarily opens to a fluid discharge side in conjunction with the reciprocating movement of a plunger of the reciprocating pump, and the gas vent pipe is connected to the branch line.

(3) Scope of Utility Model Registration In the reciprocating pump device according to claim 1 or 2, the degassable portion that communicates with the handling liquid supply system is connected to the handling liquid storage tank or the auxiliary tank for degassing. A reciprocating pump device.
