Description

Technical Field

[0001] The utility model relates to the technical field of plunger pumps, in particular to a hydraulic end assembly pump head capable of reducing wear on an inner cavity sealing surface. Background Art

[0002] The plunger pump is an important device in the hydraulic system, and can also be called the hydraulic end assembly pump head. It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. The plunger pump is widely used in high pressure, large flow and flow adjustment occasions, such as oil and gas extraction. It has high strength requirements during use and is mostly made of stainless steel. During use, due to long-term reciprocating motion, the inner cavity will wear and fall off, which seriously affects the sealing problem under high pressure, and may even cause leakage. It is not convenient to replace individual components, and the plunger pump needs to be scrapped and replaced with a new one, which seriously increases the cost of the operation.

[0003] After searching, the Chinese patent application No. 200920000106.6 discloses a reciprocating pump hydraulic end, including inlet and outlet valves inside the hydraulic end body, and the inlet and outlet valves are placed in a straight line in the vertical direction. The reciprocating pump hydraulic end in the above patent has the following shortcomings: when the device is in use, the long-term reciprocating motion of the packing box and the piston will cause wear or block loss in its inner cavity, and the sealing ring is prone to movement during liquid suction, and is prone to friction with the inside of the cavity to cause block loss. The device is not convenient for disassembly and replacement of individual components. Once block loss or high wear occurs, the entire device needs to be replaced, which greatly increases the cost of use, causing waste and unnecessary expenses. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Example 1

[0026] A hydraulic end assembly pump head for reducing wear on the inner cavity sealing surface, such as Figure 1 As shown, it includes a conveying assembly, which includes a cavity 4, a mounting frame 8 is detachably mounted on one side of the cavity 4, a packing box 17 is connected to one side of the mounting frame 8, a mounting groove is provided on one side of the cavity 4, and the packing box 17 is adapted to the mounting groove, a driving chamber 9 is detachably mounted on one side of the mounting frame 8, a piston 18 is connected to one side of the driving chamber 9, the piston 18 is slidably arranged in the packing box 17, the piston 18 is adapted to the packing box 17, and a valve seat 19 is provided on the inner wall of the cavity 4, and the valve seat 19 is provided with two sets of A slot is provided on one side of the valve seat 19, a valve plate 20 is provided through the slot, a spring 21 is provided on one side of the valve seat 19, the other end of the spring 21 is connected to the valve plate 20, a plurality of groups of blocks 22 are provided on the inner wall of the cavity 4, the blocks 22 are arranged in a step-like manner, two groups of sealing gaskets 5 are installed through the blocks 22, which are respectively arranged at the top and bottom of the cavity 4, the sealing gasket 5 is provided with a groove adapted to the blocks 22, a connector 6 is connected to one side of the sealing gasket 5, and an adjustment component for the adjustment device is provided on one side of the cavity 4;

[0027] When in use, the two groups of connectors 6 located at the top and bottom of the cavity 4 are respectively connected to the liquid inlet pipe and the liquid infusion pipe. A motor and a crankshaft are arranged in the driving chamber 9. The crankshaft is connected to the piston 18. The crankshaft is driven to rotate by starting the motor in the driving chamber 9, thereby driving the piston 18 to reciprocate in the packing box 17. When the piston rod 18 moves horizontally, suction is generated, so that a group of valve plates 20 located at the bottom of the cavity 4 can overcome the resistance of the spring 21 and move out of the groove of the valve seat 19, thereby controlling the liquid to enter the device. The pressure generated when the piston 18 is reset drives the valve plate 2 at the bottom of the cavity 4 0 reset, close the liquid inlet, and at the same time, the valve plate 20 located at the top of the cavity 4 is opened by pressure to overcome the resistance of the spring 21, so that the liquid is pressurized and discharged for transportation. When the piston 18 reciprocates in the packing box 17 and is severely worn or loses blocks, the mounting frame 8 can be removed and the fixed packing box 17 can be disassembled and replaced, thereby avoiding the replacement of the entire device. The sealing gasket 5 can be clamped by the stepped block 22, and the position of the sealing gasket 5 can be limited while sealing, so as to avoid the situation that the sealing ring moves and the friction inside the cavity causes the block to fall off;

[0028] The adjustment assembly includes a base 1, a hydraulic lifting rod 3 is fixedly provided on the top outer wall of the base 1 by bolts, two groups of hydraulic lifting rods 3 are provided, a fixing frame 10 is installed on the top of the hydraulic lifting rod 3, and the top of the fixing frame 10 is fixed to the outer wall of one side of the cavity 4, and a universal wheel 2 is installed on the bottom outer wall of the base 1, and multiple groups of universal wheels 2 are provided;

[0029] When the device needs to be adjusted during use, the device is pushed or pulled, and the position of the device can be quickly adjusted by rotating the universal wheel 2 in contact with the ground. When connecting the pipeline, the height of the device can be adjusted by the hydraulic lifting rod 3, so as to facilitate the connection with the pipeline and avoid the situation that the pipeline is not long enough and the device cannot be adjusted, resulting in failure to connect;

[0030] To facilitate infusion, Figure 2 , 3 As shown, the inner wall of the connector 6 is evenly provided with spiral patterns;

[0031] When in use, the spiral lines formed on the inner wall of the connector 6 can increase the flow rate of the liquid when it enters and flows out, thereby increasing the liquid delivery efficiency;

[0032] To support the device, such as Figure 1 , 2 As shown, the outer wall of the base 1 is fixed with a support frame 15 by bolts, and the support frame 15 is provided with multiple groups, which are respectively installed on the outer walls of both sides of the base 1, and a hydraulic push rod 13 is fixed with bolts on the top outer wall of the support frame 15, and the output end of the bottom of the hydraulic push rod 13 can slide through the support frame 15, and a foot pad 14 is installed at the bottom end of the hydraulic push rod 13;

[0033] When in use, after the device is moved to a determined installation position, the hydraulic push rod 13 drives the foot pad 14 to fall, and the foot pad 14 contacts the ground to lift the device up for support, thereby maintaining the stability of the device and making the universal wheel 2 leave the ground to avoid unnecessary displacement of the device caused by the universal wheel 2;

[0034] To reduce the bumps during movement, Figure 1 As shown, the roller of the universal wheel 2 is made of rubber material;

[0035] When in use, the rubber roller can act as a buffer when the mobile device passes through bumpy roads, which can prevent the device from being impacted and affecting the internal components. At the same time, the rubber material can increase the friction when in contact with the ground to avoid slipping.

[0036] In order to provide emergency energy, such as Figure 1 As shown, a power supply compartment 11 is fixed to the top outer wall of the base 1 by bolts, and a power display 12 is connected to one side of the power supply compartment 11;

[0037] When in use, multiple groups of batteries are arranged in the power supply compartment 11. After the power supply compartment 11 is connected to the device, it can provide emergency power to maintain the normal operation of the device during the process of repairing the power supply during an accidental power outage, so as to avoid affecting the use of the device;

[0038] To replenish the battery, Figure 1 As shown, a charging port 16 is connected to one side of the power supply compartment 11;

[0039] When in use, the battery in the power compartment 11 is replenished with electric energy by connecting the charger through the charging port 16. The charger is connected by magnetic attraction. Connecting the charger by magnetic attraction can avoid the situation where foreign objects such as stones or water stains are easily splashed into the jack of the traditional jack-type charging port and affect the use, and reduce the situation where foreign objects enter and cause short circuits.
