Description

Technical Field

[0001] The utility model belongs to the technical field of plunger pumps, in particular to a vertical plunger pump. Background Art

[0002] The plunger hydraulic pump relies on the reciprocating motion of the plunger in the plunger cavity to change the volume of the plunger cavity to achieve oil suction and discharge. It is a type of positive displacement hydraulic pump. The plunger hydraulic pump is widely used because its main parts, the plunger and the cylinder, are both cylindrical, easy to process, high matching accuracy, good sealing performance, and high working pressure.

[0003] In a vertical plunger pump with announcement number CN203783884U, the utility model discloses a vertical plunger pump, the structure of which includes a pump body and a plunger, a plunger channel is provided in the middle piece of the pump body, a plunger is movably provided in the plunger channel, a guide sleeve is sleeved on the outer surface of the plunger, a spring is provided between the bottom of the plunger and the pump body, an oil outlet valve is provided on the left side of the pump body, and an oil inlet is provided on the right side;

[0004] When the above-mentioned vertical plunger pump is used and fixed, it is directly installed through the fixing hole at the bottom of the pump body, resulting in that the upper vertical plunger pump can only be installed and used vertically, resulting in that the installation position of the device is relatively limited.

The noise will still be transmitted upward, resulting in poor noise reduction effect (adding a transverse mounting plate and an entire noise reduction shell). Therefore, a vertical plunger pump is proposed to address the above problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Specific examples are given below.

[0038] See also Figure 1-Figure 5 The utility model provides a vertical plunger pump, comprising a fixing seat 1, a mounting assembly 5 located at the lower part of the fixing seat 1, and a noise reduction assembly 6 located at the upper part of the fixing seat 1;

[0039] A pump body 2 is fixedly connected to the upper end of the fixing seat 1, a liquid inlet valve is fixedly connected to one side of the pump body 2, and a liquid outlet valve is fixedly connected to the other side of the pump body 2. A cylinder sleeve 3 is arranged on the upper end of the pump body 2, and a crankshaft 4 is arranged on the upper end of the cylinder sleeve 3.

[0040] Further, such as Figure 1-Figure 4As shown, the mounting assembly 5 includes a mounting plate 51, a connecting hole 511 is provided in the middle of the front end of the mounting plate 51, a receiving groove 512 is provided in the middle of the rear end of the mounting plate 51, and a sliding groove 513 is provided at the left and right ends of the mounting plate 51. A screw rod 52 is movably connected to the inner surface of the connecting hole 511 through a shaft sleeve, and an adjusting button 521 is fixedly connected to the front end of the screw rod 52. A connecting plate 53 is slidably connected inside the receiving groove 512, a threaded hole 531 is provided in the middle of the front end of the connecting plate 53, and a fixed button 521 is fixedly connected to the rear end of the connecting plate 53. The fixed plate 54 has three fixing holes 541 on the left side and the right side of the front end of the fixed plate 54. The lower left end and the lower right end of the fixed plate 54 are fixedly connected with reinforcement plates 55. The lower ends of the two reinforcement plates 55 close to the fixed plate 54 are fixedly connected with slide rails 56. The mounting plate 51 is located at the lower part of the fixed seat 1 and is fixedly connected to the fixed seat 1 by bolts. The screw rod 52 is threadedly connected to the threaded hole 531. The two slide rails 56 are respectively located in the two slide grooves 513 and are slidably connected to the two slide grooves 513.

[0041] Through the above scheme: when the device does not have the conditions for vertical fixed installation during use, the installation component 5 can be connected to the fixing seat 1 in the device, and then the position of the fixing plate 54 in the installation component 5 can be adjusted according to the installation space, and the device can be fixedly installed through the fixing plate 54, so that the application range of the device is wider.

[0042] Further, such as Figure 1 , Figure 2 and Figure 5 As shown, the noise reduction component 6 includes a first protective shell 61 and a second protective shell 62, and a vacuum chamber 63 is opened inside the first protective shell 61 and the second protective shell 62. The first protective shell 61 and the second protective shell 62 are fixedly connected with a sealing gasket 64 at one end close to each other, and the left front and right front ends of the first protective shell 61 and the left rear and right rear ends of the second protective shell 62 are fixedly connected with fixing ears 65.

[0043] Through the above scheme: the two protective shells in the noise reduction component 6 completely cover the pump body 2 and the cylinder sleeve 3 in the device. When the device is in use, the noise generated by the operation of the device can be reduced through the vacuum chamber 63 inside the protective shell, thereby further reducing the noise when the device is in use.

[0044] Working principle: When operating the device, the first step is to install it firmly, and then connect the inlet valve and the outlet valve of the pump body 2 so that it can be put into use immediately. If in the actual application environment, the conditions for vertical installation of the device cannot be ensured, we can flexibly adopt the strategy of connecting the installation component 5 with the built-in fixing seat 1 of the device, and adjust the position of the fixing plate 54 in the installation component 5 to adapt to different installation space layouts, thereby ensuring that the device is firmly installed. This design greatly broadens the adaptability of the device and enables it to function in different environments.

[0045] In addition, in order to further enhance the user experience, a noise reduction component 6 is integrated in the device. This component cleverly uses two protective shells to completely wrap core components such as the pump body 2 and the cylinder liner 3. The vacuum chamber 63 constructed inside the protective shell is like a natural sound barrier, which can effectively absorb and isolate the noise generated during the operation of the device, significantly reduce the noise impact of the equipment on the surrounding environment during operation, and create a quieter and more comfortable use environment for users.
