Problems solved by technology

[0003] However, the existing air-driven screw pumps cannot reduce the vibration generated when the air-driven screw pump is in use. The noise generated by the air-driven screw pump is relatively large, and the air pipeline connected to the air motor cannot be tightened. If it falls off, it is inconvenient to adjust the flow rate of the liquid inlet pipe, and it is inconvenient to choose a suitable liquid inlet speed for liquid inlet

Embodiment 1

[0030] Such as Figure 1-5 As shown, the present invention relates to a pneumatically safe pneumatic screw pump, including a support base 1, an air motor 2 is fixedly installed on the upper surface of the support base 1 close to one side, and the upper surface of the support base 1 is fixed close to the other side The pump body casing 3 is installed, the base 4 is arranged under the support base 1, the shock absorbing mechanism 5 is connected between the base 4 and the support base 1, the output end of the air motor 2 is connected to a transmission shaft 6, and the pump body casing 3 One end is connected with the second transmission shaft 7, and the other end of the pump casing 3 is connected with a liquid outlet pipe 8, and the top of the pump casing 3 is connected with a liquid inlet pipe 9, between the first transmission shaft 6 and the second transmission shaft 7 A coupling 10 is connected, and the top of the air motor 2 is fixedly installed with an air connection seat 11,...

Embodiment 2

[0039] On the basis of Embodiment 1, a method for using a pneumatically safe pneumatic screw pump comprises the following steps:

[0040] S1: Connect the air pipe joint 12 to the air pipe, and connect the liquid inlet pipe 9 and the liquid outlet pipe 8 to the infusion pipe respectively;

[0041] S2: Pass the air pipe through the No. 1 tightening block 1301 and the No. 2 tightening block 1302 to connect with the air seat 11. The No. 2 tightening block 1302 is relatively movable through the connecting column 1303, the anti-drop joint 1304 and the return spring 1305. The air pipe is clamped;

[0042] S3: The air motor 2 starts to work, the air motor 2 drives the No. 1 transmission shaft 6 to rotate, the No. 1 transmission shaft 6 rotates through the coupling 10 to drive the No. 2 transmission shaft 7 to rotate, and the No. 2 transmission shaft 7 rotates through the universal joint 16 The feeding screw 17 is driven to rotate, and the feed liquid is delivered to the feeding chamb...

Abstract

The invention discloses a pneumatic safety type pneumatic screw pump and a using method thereof. The pneumatic safety type pneumatic screw pump comprises a supporting seat, a pneumatic motor is fixedly installed at the position, close to one side, of the upper surface of the supporting seat, a pump body shell is fixedly installed at the position, close to the other side, of the upper surface of the supporting seat, and a base is arranged below the supporting seat. A damping mechanism is connected between the base and the supporting seat, the output end of the pneumatic motor is connected with a first transmission shaft, one end of the pump body shell is connected with a second transmission shaft, the other end of the pump body shell is connected with a liquid outlet pipe, and the top of the pump body shell is connected with a liquid inlet pipe. A coupler is connected between the first transmission shaft and the second transmission shaft. The pneumatic safety type pneumatic screw pump and the using method thereof belongs to the field of delivery pumps, vibration generated during working of the pneumatic screw pump can be reduced, a gas delivery pipe connected with the pneumatic motor can be tightened, and the flow of the liquid inlet pipe can be conveniently adjusted.

Description

technical field [0001] The invention relates to the field of conveying pumps, in particular to a pneumatically safe pneumatic screw pump and its usage method. Background technique [0002] A pump is a machine that transports fluid or pressurizes the fluid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali, emulsion, suspoemulsion and Liquids such as liquid metals can also transport liquids, gas mixtures and liquids containing suspended solids. Pumps can usually be divided into three types according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps. This scheme specifically involves a pneumatic safety pump. Type pneumatic screw pump and its use method; [0003] However, the existing air-driven screw pumps cannot reduce the vibration generated when the air-driven screw pump is in use. T...
